If the breaker has not been used for a month, put the circuit breaker air cushion on the back of the circuit breaker, then release the nitrogen gas from the rear cylinder, push the piston into the cylinder, and place it in a dry place in the room, so as to prevent the piston from burning. Rust and damage to piston seals.
If the breaker is used for less than two months, its oil seal will be deformed due to long-term changes, so when we use it again, it should be replaced with a new oil seal.
When parking the small excavator, run the air conditioner once a month. After preheating the cab, let the refrigerant circulate in the air conditioner system for a week to ensure that a certain thickness of oil film is maintained at the seal of the air conditioner system to prevent refrigeration. agent leakage.
Start the engine once a month to apply a new oil film to the surface of the moving parts to prevent rust or dry grinding.
In winter, the belt of the small excavator is prone to problems, and we need to check it frequently. If the belt is slippery or too tight, the belt will be worn.
Let's talk about the use strategy of small excavators;
First, the slope leveling operation. When one-sided trimming, we should put the machine on the ground to prevent the body from shaking. In order to better grasp the coordination between the boom and the boom movement, it is necessary to control the speed of the two for plane trimming. indispensable.
2. Running in soft areas or water. When working in soft areas, you must first understand the compactness of the soil, pay attention to the limited excavation range of the bucket, and prevent some accidents such as landslides and deep settlement of the car body. When working in water, Pay special attention to the allowable water depth range of the body. If the water level is too high, the inside of the slewing bearing will be poorly lubricated, and the fan blades of the engine will be folded by water, which may cause the intrusion of water to cause short circuit or damage to circuit components.
Third, the loading operation, the body should be in a horizontal and stable position, otherwise it is difficult to precisely control the rotation and unloading, which prolongs the cycle time, and an appropriate distance between the body and the truck should also be maintained, in order to prevent the rear end of the body from 180 When the truck collides with the truck when turning, the field of vision is wide and the work efficiency is high. The angle of rotation should be correctly grasped to shorten the rotation time. When the position of the truck is lower than the excavator, the time for the boom to rise will also be shortened, and the line of sight will be maintained well. , this time put in sand, gravel and boulders to reduce the impact on the car.
Fourth, hoisting work, when the hydraulic excavator is used for hoisting operations, the environment around the hoisting site should be confirmed first, and high-strength hooks and wire ropes should be used. When hoisting, special lifting equipment should be used as much as possible. The operation mode should be selected in the micro operation mode, the movement should be balanced slowly, and the appropriate length should be selected. If it is too long, the lifted object will swing more, which is difficult to control accurately. The position of the bucket should also be adjusted correctly. To prevent the wire rope from slipping, the construction personnel should not approach the lifting object to avoid danger caused by improper operation.

Introduction to Excavator Hydraulic Breaker
Hydraulic breakers are referred to as "breakers" or "breakers". The power source of hydraulic breakers is the pressure provided by excavators, loaders or pump stations. work efficiency. The principle of choosing a hydraulic breaker is to choose the most suitable hydraulic breaker according to the model of the excavator and the operating environment. According to the analysis of Li Gong, a senior consultant of Hydraulic Talent Network, my country's hydraulic breaker is mainly imported from abroad. Well, Li Gong from Hydraulic Talent Network reminds everyone not to forget to support domestic technology so as to have better development.
