Excavator walking slowly, how to do? Provide technical support!

The main performance of excavator's slow motion can be roughly divided into three categories: slow single motion, slow whole vehicle motion and slow warm-up machine motion. We will make a concrete analysis of the above three issues.

Analysis of causes (technical support for excavator, excavator walking, and excavator walking delay)

1. Check whether the pressure of relief valve of relevant components of excavator is too low;

2. Check whether the pump, low-pressure sensor and multi-channel valve are in fault;

3. Check whether the relevant solenoid valve and valve element are in fault.

Solutions

1. First, check whether the whole machine is maintained on time, whether the hydraulic oil is replaced on time; whether the hydraulic oil circuit is blocked, please check the system pressure at idle speed, and check whether the return oil filter element is blocked;

2. If the output power of the engine is too low and the power is insufficient, please analyze the output of the engine with DX data, and check whether all cylinders can work at the same time; check whether there is black smoke in the engine, and if the nozzle is seriously worn, the engine power will also be reduced;

3. The output of the hydraulic pump is insufficient, and the relevant pressure can be tested when entering the service diagnosis system;

4. Insufficient pilot pressure causes insufficient opening valve core pressure, resulting in insufficient flow and slow action;

5. If there is circuit problem, check the CPU, high and low pressure sensor, solenoid valve and circuit fault of excavator.

6. Check the oil in time to see if it is clean. If there is dirt, replace it immediately. If the oil is too dirty, replace it. Check if there are copper scraps in the oil inlet filter screen, which causes wear of the main pump. Disassemble it for inspection.
