These six types of excavator maintenance can not be done

Excavator maintenance of these six can not do, wheel tire pressure is too high, wheel excavator in the use of the process, tire maintenance is very important. Generally speaking, the tire pressure can be used according to the mechanical specification during the time when the temperature is suitable, such as autumn and winter, while the high temperature summer and the low temperature winter are not suitable for the use of the specification pressure, but need a little lower than the standard air pressure, so as not to cause tire damage, affect the service life and work efficiency. Do Not Change Oil for a long time, oil has to protect the engine internal smooth and clean important role, many excavator drivers know the need to add oil in time, so as not to lack of oil. But most people have ignored the easily polluted properties of engine oil, such as carbon deposition and other pollutants easily into the oil, thus affecting the normal use of oil, and then affect the life of the engine. Butter is widely used in excavators. Many excavators often smear butter on the joints of the big and small arms of excavators. It has the function of lubrication, butter doesn't come from anywhere. For example, on the cylinder gasket, some people like to put a layer of butter on the cylinder gasket, think it can enhance the air tightness of the cylinder, but this will actually damage the machinery, because the butter will enter the cylinder at this time, because the use of high temperature mechanical burning, deterioration, but make the cylinder gasket can not seal. The screws are too tight. In the process of disassembly and assembly of excavators, many people tighten the screws as tightly as possible, but in fact it is not so. The screws can not be too tight. If you tighten the screws hard, not only will it not be safer, on the contrary, it will cause the bolt to break, which will lead to the screw slip, and then affect the mechanical firmness, the operation will cause mechanical fall off and other conditions, resulting in unnecessary personal safety problems. When the water tank is boiled, the water is heated. After a long period of high-intensity operation, the excavator sometimes appears the phenomenon that the water in the water tank is boiled because of the difference in heat dissipation or the water shortage in the water tank. When this happens, must not add cold water to the water tank in order to cool down, because this sudden change in heat and cold will cause the water tank cracking, affecting the service life of machinery. Encounter this kind of situation, should stop work immediately, let water tank cool down by itself, return to normal condition gradually. When the Piston is heated by open flame, because the Piston and the Piston Pin are in an interference cooperation, the piston should be expanded by heating first. When heated, the Piston can be heated evenly in hot oil to expand slowly, remember not to heat directly with open flame. Some repairmen will put the Piston on the open flame direct heating, this approach is very wrong, because the piston parts of uneven thickness, the degree of expansion and contraction will be different, the open flame heating will make the piston heating uneven, causing the Piston to deform. At the same time, the piston will be damaged and wear-resistant function will be greatly reduced, the service life will be shortened. Next: What can we do to reduce the faults of the machines and extend the service life of the pick-up machines?
