Emergency treatment of excavators

First, the emergency treatment of the excavator in the water

Excavators are sometimes easily caught in water during construction. In order to minimize the mechanical loss of the excavator spare parts caught in the water and the trouble of cleaning, assembling and repairing afterwards, the following points should be noted:

1. Prevent the hydraulic tank from entering the water. Since the hydraulic oil tank is completely sealed when the excavator is working normally, there is a certain pressure in the tank. If the oil enters the water, the oil in the tank will be cooled after it is cooled. After reaching a certain value, the air will be sucked in, and there is a breath in the upper part of the tank. The mouth, some excavators, the breathing port is led to the middle and lower parts of the hydraulic tank. If the water level reaches the breathing port of the tank, it will absorb water. In this case, the position should be raised first and higher than the water surface.

2. Prevent the engine from entering water or sediment. The engine inlet water is mainly easy to enter the cylinder from the air filter; the second is to enter the crankcase from the engine exhaust pipe. Once in the water or sediment, it needs to be handled by professional technicians.

3. Emergency treatment of excavator electrical parts. Once the excavator is trapped in the water, the fuse should be taken out immediately, the battery cable should be removed, the computer board should be removed, and other generations of professionals should handle it.

4. If the excavator has a rollover, the oil may enter the cylinder from the supercharger, or it may enter the cylinder from the opening of the piston ring. The case should be handled by a professional.

Second, the emergency treatment of hydraulic spare parts cylinder rod

In the construction of the construction site, if the hydraulic cylinder rod is damaged, bruised or inadvertently clicked, the surface of the cylinder rod is damaged, and the project is protruding or sunken. At this time, the work should be stopped immediately. It is strictly forbidden to take the cylinder rod into the cylinder. The oil seal and the guide sleeve will be pulled. After the cylinder rod damage occurs, if the damage is not serious, use gauze, oil stone or temporary honing stone to honour the protruding part, and the water hole or burr should be worn off in the depression, confirm that it is not higher than the plane. It can be used temporarily if it feels smooth by hand. If it is traced, it is normal. After the conditions are met, send it to the repair shop for repair. https://jnjmzm.wixsite.com/sdjygcjx
