Used excavator – summer maintenance strategy. Thailand Excavator sprocket
Summer is here, and the high temperature is also a kind of tempering for the excavator, so what should we pay attention to to maintain the performance of the excavator? In addition to the normal maintenance of the excavator, the following aspects should also be noted:
NO.1
▊Check whether the antifreeze fluid has expired and replaced.
When it comes to antifreeze, we may have the wrong idea that antifreeze prevents refrigerant from expanding and cracking radiators and freeze cracking engine blocks or covers after a cold winter shutdown, and thinking it can be replaced in winter. In fact, I can’t recognize that antifreeze is used not only in winter but year round.Thailand Excavator sprocket
Antifreeze has two characteristics of low temperature and high boiling point.
Therefore, it not only ensures the normal operation of the vehicle refrigeration system in winter, but also prevents the cooling circulating water from burning in summer and prevents the “boiling” of the cooling circulating water.
Therefore, in the hot summer, we must pay attention to check whether the antifreeze has expired, and if it expires, we must remember to replace it regularly. General antifreeze can be used for 1000 hours, real antifreeze can be used for 2000 hours, different brands of antifreeze are different, do not mix them.Thailand Excavator sprocket
NO.2
▊ Check whether the water storage tank, gear oil radiator and air conditioner condenser are blocked.
Confirm the excavator in autumn, winter and spring, these places are easy to deposit some dead branches and rotten leaves, or absorb fluff and fluff. In addition, there are some excavator water storage tanks and radiator back covers, the sponge is damaged or peeled off, causing abnormal air intake of the fan, resulting in poor heat removal from the water storage tank, gear oil radiator and car condenser. Always pay attention to the number of water temperature grids. When a certain grid number is reached, effective measures must be taken. You can choose to park in a cool place nearby and wait for the temperature to cool down. Remember not to stop the fire immediately to prevent the engine from overheating and causing safety accidents such as cylinder knocking.Thailand Excavator sprocket
NO.3
▊Appropriate use of lubricating oil.
In summer, the outdoor temperature is high, the working temperature of the excavator is high, and the temperature has a great influence on the circulation of the lubricating oil: the temperature rises, the lubricating oil becomes loose, the adhesion of the lubricating oil is reduced, the outflow is convenient, and the lubrication of the working device and the rotating device is caused. Reduced performance.
In addition, under relatively high temperature conditions, it is easy to expand the evaporative loss of lubricating oil, and the oxidative quality change of air and the separation of oil from nuclear fluid are more serious.Thailand Excavator sprocket
Lubricants with better continuous high temperature performance can also maintain their adhesion at relatively high application temperatures, and the entire process of qualitative ineffectiveness is relatively slow. Note: Do not use lubes that look like wheat flour.
NO.4
▊When the car is wading, it is not necessary to let the water exceed the center of the upper roller.
Finally, the crawler-type tightening cylinder should always be loose and firm (remove the sludge in the hydraulic cylinder, and there is more rain in summer to avoid corrosion of the hydraulic cylinder).
After the excavator works for a day, the small accelerator pedal should run for a few minutes, and then stop after the sleep temperature drops significantly. In summer, when the excavator is placed for a long time, the diesel fuel tank should be filled with diesel engines to prevent the diesel fuel tank from rusting. When placing, remove the battery and place the battery in a dry and waterproof place to keep the appearance clean and dry. When cleaning the excavator, do not spray water directly on the electronic components. If water gets in, the electrical components will be ineffective or common failure.
Summer maintenance is not difficult, understand the above points, that way, even in the hot summer, you can let your machine spend peacefully!Thailand Excavator sprocket
