Komatsu excavators may encounter the failure of holding the excavator when they are in use. Generally, when the failure of holding the excavator occurs, the excavator maintenance worker needs to determine whether the failure is caused by the mismatch between the pump power and the engine power of the excavator or the failure is caused by the insufficient engine power of the excavator. Our excavator maintenance factory will explain the two failure causes and judgment methods in detail.
Chongqing meiruite construction machinery equipment is one of the professional construction machinery maintenance manufacturers. It has a professional hydraulic system debugging platform and computer diagnosis instrument in China. Since its establishment, the company has always been in line with the enterprise philosophy of quality assurance and people-oriented, and has won the support and trust of customers. At present, the development of a large-scale and professional technical maintenance team and the possession of more professional maintenance equipment are the main driving force for the development of the company. Now it has developed into? It is one of the maintenance manufacturers of construction machinery.
1. Judge whether it is the pump or the engine that causes the failure of the excavator to hold the car according to the environment of the excavator operation.
2. If the power of the hydraulic pump of the excavator is greater than the power of the excavator engine, the excavator engine will emit black smoke, suffocate the vehicle and even shut down the excavator.
3. Check whether the pump power matches the engine power with a pressure gauge? (generally, they are matched. If the pump power and engine power do not match, it needs to be adjusted.)
In general, if the pump is the reason, the displacement of the pump does not decrease when the pressure exceeds the start-up pressure, so the engine will shut down.
Excavator maintenance experience:
In the event of failure, it is first necessary to check whether the pump and engine power match, and then patiently check step by step whether the pump or engine causes the excavator to hold up.
