How to maintain MINI excavator in high temperature
Posted: Oct 25th, '24, 04:00
First of all, we must judge the hydraulic high temperature fault of the MiNi excavator according to the method from simple to complex, from external to internal, from intuitive to detection. The troubleshooting procedure is as follows:
First check whether the hydraulic oil radiator is dirty, hydraulic oil level, oil quality, check the filter element, if there is a problem, it should be cleaned and replaced in time; Check the hydraulic system for leaks. If there are multiple leaks, replace the seals and damaged parts in time.
Use a multimeter to check for circuit problems and sensor damage. Use a direct temperature tester to test whether the actual hydraulic oil temperature is too high.
The above tests are normal. Check the return check valve of the hydraulic system. They should be removed to check if the spring is damaged or stuck. If you have any problems, you need to clean or replace them.
Check the hydraulic pump of the MiNi excavator for abnormal noise and excessive oil discharge from the drain pipe. If the working pressure is too low, use the pressure gauge to test the working pressure of the system;
The above inspection is a normal standard, should check the supercharger, high pressure pump and fuel injector engine power problems;
