Winter maintenance is crucial for excavators as the cold temperatures and harsh weather conditions can have a negative impact on the machine. This article will provide some key winter maintenance measures to ensure that excavators operate efficiently during the cold season. Fluid Protection: In winter, condensation of fluids can damage critical components of the excavator. It is important to ensure that the engine coolant and hydraulic oil maintain the appropriate temperature and viscosity. Use antifreeze to protect the coolant and ensure that the hydraulic oil has the proper viscosity to ensure the normal functioning of the machine. Battery Maintenance: Low temperatures can adversely affect battery performance. Regularly check the battery's charge level and electrolyte levels, and ensure that the battery connections are secure. If possible, use a heater to maintain the battery at an optimal temperature. Fuel Management: In winter, fuel can freeze, affecting the fuel supply of the excavator. Use fuel additives with anti-freeze properties to prevent fuel from freezing, and ensure that the fuel filter is functioning properly. Additionally, regularly drain off waste oil and water to ensure the proper operation of the fuel system. Tire and Track Maintenance: Low temperatures and snow in winter can have a negative impact on the tires and tracks of the excavator. Inspect and adjust tire pressure to the manufacturer's recommendations, and consider using winter-specific tires if necessary. For excavators with tracks, ensure that the tracks are free from ice and snow buildup and check for any signs of wear or damage. The operator's comfort and safety are essential during winter operations. Ensure that the cabin is properly insulated and equipped with heating to keep the operator warm. Pay attention to visibility by clearing snow and ice from the windows and mirrors. Also, check the effectiveness of the defrosting system.

Agricultural excavator walking without strength is the most common fault in the walking process, sometimes it is a unilateral fault sometimes both sides of the walking are faulty, resulting in this fault is generally due to the following reasons: 1, the central rotary joint internal leakage, oil leakage. Agricultural excavator central rotary joint is the upper body hydraulic circuit connecting the important hub of the chassis, when the central rotary joint sealing effect is poor will produce internal leakage or oil leakage phenomenon, drive the hydraulic motor of the hydraulic oil can not fully reach the hydraulic motor, part of the hydraulic oil through other circuits to return to the tank, resulting in a loss of pressure in the hydraulic circuit, resulting in hydraulic motors are not strong. 2、Walking motor internal leakage, failure. Walking system by walking balance valve, walking safety valve, walking speed switching valve, walking speed switching cylinder, walking brake cylinder, throttle valve and walking motor composition, when a valve group produce internal leakage will cause the walking system hydraulic circuit pressure loss, resulting in walking no power. 3, hydraulic pump pressure is insufficient, pump control circuit failure. Hydraulic pump pressure is also an important cause of walking without power, leading to hydraulic pump pressure is mainly due to pump leakage, pump control system failure, resulting in pressure loss. 4, the main control valve internal leakage. The main control valve is a multi-spool valve group, when the working time is long or when the hydraulic oil contains impurities will lead to wear and tear of the spool, when the control of the hydraulic circuit of the walking system spool wear and tear is too large, there will be an internal leakage, resulting in a loss of pressure in the hydraulic circuit, resulting in the walking of the lack of strength. 5, the pilot system secondary pressure oil pressure is insufficient. Pilot system secondary pressure oil is output by the proportional control valve, when the agricultural excavator cab walking valve leakage, jamming will lead to the pilot secondary pressure oil pressure is insufficient to push the main control valve spool in place, resulting in a reduction in the walking system hydraulic circuit flow. The above points are the main reasons for the agricultural excavator walking without strength, understand these, when encountering similar failures in the future, the constructor can be resolved by himself.

Wheeled excavators are excavators that can be driven on the ground, and they typically use a hydraulic system to control the movement of the arm and bucket. Wheeled excavators are generally better suited to working on flatter ground than crawler excavators because they can move faster, which increases productivity. wheeled excavator  Most foreign wheel excavators travel at a speed of 25-40km/h The wheel excavator is a construction type wheel and tire walking excavator with fast walking speed, long-distance self-transition and quick replacement of various operating devices. The advantages of mobility, flexibility and efficiency have won over customers. At present, the driving speed of foreign wheel excavation is mostly 25-40km/h, and most of the domestic excavation speed is 20-35km/h, and some can even reach 54km/h. It can be said that although wheel excavators do not occupy a mainstream position in China, their technical level is not behind. However, it is important to note that a wheeled excavator is not a vehicle specifically designed to travel, but rather a tool for digging and moving earthmoving materials. Therefore, when using a wheeled excavator, extra care is required to avoid collision or damage to other facilities or personnel during driving. In summary, the top speed of a wheeled excavator depends on many factors, including the size and power of the machine, ground conditions, and the skill level of the operator. If you have specific questions about a particular machine or excavation project, it is recommended that you consult a professional contractor or equipment dealer for more detailed information.

Small excavators have the advantages of small size and flexible steering, and can be used in a variety of narrow working spaces. Many limited working spaces can choose small excavators. Various problems are unavoidable in the use of small excavators, such as speed drop problems, so let’s analyze the causes of speed drop of small excavators. 1.Cause excavator speed to be too slow, because the clearance of solenoid valve is too large, which causes insufficient oil supply, thus causing engine to slow down. 2.It is suggested to check whether the oil is deteriorated and check whether there are impurities in the oil collection product and whether the oil pipeline is blocked. 3.The poor quality of fuel or the high content of fuel water in the engine will result in insufficient power and speed drop of small agricultural excavator engine. 4.In addition, incorrect valve clearance of excavator, wrong injection timing, damaged turbocharger, etc., will cause speed drop. To solve the problem of small excavator speed drop, we can investigate from the following aspects, find out the root cause of the problem, apply medicine to the case and solve the problem. Today’s content is shared with you, and you are welcome to make valuable suggestions.

In 2021, despite the more complicated international situation, with the spillover of China's manufacturing capabilities and comprehensive national strength, the scale of my country's cross-border e-commerce will reach 1.98 trillion yuan, out of a high growth rate of 15%, and usher in a historical dividend period. Among them, the foreign trade of the machinery industry performed well, with the total import and export volume of the year reaching 1.04 trillion US dollars, breaking the 1 trillion US dollar mark for the first time. Jiang Chaoxiang from Jining, Shandong has nearly 10 years of experience in selling machinery on the international station. For the rapid growth of cross-border e-commerce and machinery industry in recent years, Jiang Chaoxiang is fortunate to be a witness and participant. Beginning in 2020, their monthly inquiries on the international site exceeded 10,000, and the turnover increased by 300% for two consecutive years. Last year's sales exceeded 100 million directly. He set up his own factory and registered his own brand. Quit a high-paying job and start at 0 At the beginning of 2017, Jiang Chaoxiang quit his job for nearly 4 years because of different customer service concepts. He devoted himself to Shandong Hightop Group Co., Ltd. (hereinafter referred to as Hightop Machinery). At that time, his idea was to do it himself instead of spending energy to persuade the former company to transform. "At that time, my three partners had been working at Hightop Machinery for two years. One person, one computer, one desk, and they talked about their own business. Rather than a company, it was better to pool money to open a business. An international station. The company has no concept of management, no business strategy, or even division of labor." Jiang Chaoxiang recalled the situation when he just returned to the company.  300,000 loss in the first year In order to quickly turn the situation around, Jiang Chaoxiang put a large number of industrial products and machinery into the store at the international station. Because the store is too cluttered, he doesn't know much about the products. The buyer asks him a few more questions, and he gets stuck. He asks more and buys less. At the former company, the factories were their own, and production was customized and scheduled around their needs. Today, a screw has to be purchased. The factory saw that he had just entered the business, and the order volume was not large, so he did not want to chat with him at all. Jiang Chaoxiang still vividly remembers the scene of being hanged in the factory for several hours. In 2017, they lost more than 300,000 yuan. Jiang Chaoxiang brought the three partners together to discuss whether to continue. The four of them borrowed 100,000 yuan to start over. They are aware of their own problems: the store has no main products, the products are too messy, and the operators do not know enough about the products; the upstream supply chain cannot keep up with the needs of customers, and they do not understand the rules of the international station. To use the most popular words these days, they do not have an advantage in the field of people and goods.  Five ways to turn losses into profits At the meeting, Jiang Chao decided to set spraying machines as his main product, and introduced excavators and other high-unit price and profitable products, focusing on following up with customers in Europe and the United States. Jiang Chaoxiang and everyone in the team said that the payment for goods is recovered through credit guarantees, which reduces buyers' distrust of trading companies, and accumulates data on stores in the international station to increase the weight of stores. In order to liberate employees from inefficient work, Jiang Chaoxiang asked employees to ship goods through the cross-border supply chain of the international station. Jiang Chaoxiang, who had been in contact with Yidatong in the last company, still remembers the convenience of Yidatong for making customs declaration materials and the service of paying tax refunds in the fastest 3 days. At the same time, everyone in the team is required to study the platform's ranking rules and gameplay, and they are required to have a full understanding of their peers. At that time, they pulled out and studied the popular mechanical products on the international station one by one. Team OUTING Do the best you can. In February 2018, Jiang Chaoxiang signed up for the New Trade Festival at the International Station, and was elected as the captain of Jining by local friends. The performance of their legion became the champion of the northern region. Looking at the revenue of the month, he and the team felt the joy of victory for the first time. Today, the winner's certificate is still hanging in Jiang Chaoxiang's office. At the end of 2018, Jiang Chaoxiang took a loan of 100,000 yuan from Ali Finance and opened his first gold shop. With the blessing of the two stores, their sales exceeded 6 million yuan that year.  Roll yourself out of the industry In 2021, Jiang Chao related a crazy thing. When the whole company was busy with product selection and delivery, he registered his own factory and announced that he would develop his own brand of excavators. mini excavator In recent years, although excavators have become the main product of their store, they know nothing about the technology and production of excavators, and several partners have zero factory experience. After I finally made some money, I rashly started a factory, can I do it? "I have already figured out the foreign demand in this industry, the capabilities and prices of domestic factories." Jiang Chaoxiang shared his original intention to set up a factory, "When communicating with buyers, those big dealers often Looking at my photos, I know that we didn't make it, and I don't want to talk to me any more, and I lost the opportunity for cooperation in vain." After the factory was registered, Jiang Chaoxiang paid a lot of money to invite a master to help. In order to hurry up, he spent the whole night with the master to read the drawings and assemble the production line. In less than half a year, he abruptly turned himself from a layman to a technical master. The company has 20 excavator patents. Excavator patent From assembling the production line to developing new products, it took others half a year, but he sent the first batch of goods, more than 200 excavators, on a cargo ship to the United States in two months. In the past two years, in order to get more orders, some peers have continued to cut prices and sell themselves. In order to control costs, the configuration can only be reduced. This foreign trade person who has his own perseverance in his heart does not agree with this method of taking orders by reducing configuration and affecting customer experience and industry reputation. On the one hand, he purchased steel plates as accessories to reduce the cost of existing models and benefit customers. At the same time, he is full of firepower to develop new brands and models, and the configuration of new models is constantly improving. He hopes to retain customers with word of mouth.  Logistics services help foreign trade dreams Jiang Chaoxiang delivered most of the accessories and spraying machines through the international station, especially under the trend of epidemic situation and industry inversion, he could choose cost-effective shifts in the background of the store in real time to reduce shipping costs. At the same time, the backstage of the international station can check the logistics track at any time, which greatly increases the certainty of arrival. On March 17 this year, the international station released a new international station logistics service. Seeing the service guarantee and price of the international station shipping service, Jiang Chaoxiang began to try to use the international station shipping FCL service again. Jiang Chaoxiang was deeply impressed by the shipping service guarantee at the international station. On April 18, Xinhua announced that in the first quarter of this year, China's total import and export of goods increased by 13.3% year-on-year. In the past first quarter, he and the team basically completed their goals. For this year's goal of 280 million, Jiang Chao is full of confidence.  Hightop Machinery Factory latecomers When asked about the secret of going from an annual loss of more than 300,000 yuan to an annual sales of over 100 million yuan, Jiang Chaoxiang summed it up as long-termism, in-depth research on people, goods, and patterns. 1. Long-termism: Open a store offline, and you can see customers coming in when you open the door. If you don’t make a deal, or leave immediately, it will be effective in the short term. Novices come in and are easy to fall into. If you don’t see benefits in 3-5 months, you will lose confidence. To do foreign trade, customers, data, and products all need to be precipitated, which is a long-term and systematic process. 2. Thoroughly research the people and goods market: Take the international station as a traffic channel, one person with one computer, waiting for customers to inquire, which is the current situation of many foreign trade people. What is the demand for your product? How to get the goods and the price? Is your people management keeping up? Have you figured out the platform's scene and traffic play? If you don't know this, how can you push yourself abroad? 3. Entrepreneur pattern, do you want to be big or small: our salary is quite high now, the employee said I want 3000, I may give 5000, I will tell him clearly, I will train him to that point . But you have to think about it, work for money or work for life. Talking about social contribution is a bit false, you have to do it, and you have to bring your employees to do it. Let everyone make money together, and let employees have a higher social status and higher family value. No one wants to be with you.

In the summer when the weather is hotter, it can be said that it is difficult for people to go out. Why are mechanical equipment not a living body also afraid of heat? Yes, the small roller equipment is also afraid of high temperature, and the high temperature will make the small roller equipment difficult to use. Appropriate temperature, whether it is work or rest, people's mood is good, it is not difficult to understand, small road rollers also need a suitable temperature environment when working, if the equipment is used in an environment that exceeds the working temperature, it will give the equipment itself. cause great damage. Due to the hot weather in summer, the engine temperature is high, and it is easy to cause failure, resulting in the engine not being able to dissipate heat normally and reducing power. Irregular maintenance of the engine will lead to the drop of high temperature operation and the lack of oxygen in the lubricating oil, resulting in carbon deposition. Experiments show that the engine power will drop by about 3% when the working temperature rises by 20°C when the engine exceeds 30°C. Small rollers often work in an environment of 50°C, which means that the engine power is reduced by about 4%. The high temperature causes the viscosity of the lubricating oil to decrease, and it is not easy to form a lubricating oil film, which reduces the lubrication effect. Under high temperature conditions, the anti-oxidative stability of lubricating oil drops sharply, which directly causes the deterioration of lubricating oil, so that the colloid and sediment of lubricating oil adhere to the surface of piston, cylinder wall and other parts, and the thermal conductivity declines, aggravating the deterioration of lubricating oil. Wear on components. The reduction of the working oil quality of the road roller at high temperature is easy to cause extravasation and internal leakage, which reduces the rate of the hydraulic drive shaft system and makes the hydraulic drive shaft weak. Everyone has learned about the hazards of small road rollers at high temperatures and how to prevent them. I hope it can help everyone. When purchasing, you can choose some well-known vibratory roller manufacturers to buy. Because manufacturers with a certain reputation have certain advantages in the technical team, and have a good reputation. Our company specializes in the production and manufacture of presses, providing you with high-quality small roller machinery and equipment. At the same time, we also have a relatively complete after-sales service, so that you can be completely assured of the quality when using the equipment.

For the problem of high water temperature, it is generally very common in summer, but in winter, this situation sometimes occurs. If this problem occurs, the small excavator is faulty. So what should I do for this kind of problem? Solve it?  First of all, let's analyze the reasons for the failure of small excavators 1. When the temperature is too high and the air conditioner is turned on, the idling speed is unstable and the rotation speed fluctuates too much, the acceleration is weak, and the engine has abnormal noise. When the small excavator is repaired, check the temperature difference between the upper and lower water pipes of the water tank. If the temperature difference is too large, it is necessary to check the opening of the thermostat and whether the water pump has a fault that the speed is lost. The temperature difference between the upper and lower water pipes of the water tank should not be too large. 2. After the hot car is turned off for ten minutes, it is not easy to start the car when it is started; sometimes it will automatically turn off when the hot car is running. Solution: After the car is warmed up, check the water return of the return pipe at the upper end of the antifreeze water tank. If the return water is not smooth or blocked, the water temperature will be too high. Warm reminder: Do not blindly disassemble and replace parts in the maintenance of small excavators. 3. When the car is cold, the cooling temperature of the air conditioner is very cold, and the cooling effect of the air conditioner is not obvious when the car is warm; and there is a large resonance buzzing sound in the air conditioning system. Due to the irregular addition and replacement of antifreeze during the maintenance of small excavators, the engine water channel and water tank will be blocked in advance, and the water temperature will be high. Antifreeze is replaced every two years, and original parts must be used when replacing and adding. 4. When the small excavator is idling, the engine water temperature gauge shows too high, the working time of the electronic fan high-speed gear is too long, the engine noise increases, and the fault is most obvious when the temperature is too high and the air conditioner is turned on. When the small excavator is repaired: Check whether there is too much dust between the condenser and the water tank, and thoroughly clean it with high-pressure air to ensure that the water tank and the condenser have good heat dissipation performance. Usually pay attention to wipe the dust between the condenser and the water tank. 5. When the hot car is idling, the air conditioner compressor clutch is frequently sucked and disconnected, or even disconnected, causing the hot car air conditioner not to cool. The high pressure at the high-pressure end of the air-conditioning system is too high; the air-conditioning refrigerant or air-conditioning refrigeration lubricating oil is overfilled; the self-adjusting function of the internal self-adjusting air-conditioning compressor fails, causing the high pressure to be too high; and the air-conditioning condenser Blockage, the above faults will increase the load of the engine, consume the heat dissipation performance of the cooling system, and lead to the occurrence of faults with excessive water temperature. Warm reminder: Too little or too much refrigerant in the air conditioner will reduce the cooling effect.
