Hydraulic transmission system fault diagnosis method
regular checking
The hydraulic transmission system should be inspected regularly by relevant personnel, which not only reduces the possibility of failure, but also saves substantial economic costs. In the process of checking the work, the relevant staff need to have a comprehensive understanding of the hydraulic transmission system, and master the perfect professional technology, if the system is found in the inspection problems, it is necessary to deal with and solve the problem in time.
diagnostic observation
So-called observation of diagnosis is to carefully observe the faults of hydraulic transmission system, so, common failure problems mainly for leaks, fever, abnormal noise and manipulation, etc., can find the problem after observation point to try to manipulate, and then use methods of short circuit and open circuit on the depth of problem diagnosis, and steps, the diagnosis results are detailed records, After a series of comparison and analysis, can accurately judge the hydraulic transmission system failure parts and causes.
Instrument diagnosis
FFor instrument diagnosis, is to use universal hydraulic detector (PFM) to monitor the temperature, speed and flow of the construction machinery hydraulic transmission system, if the transmission system hydraulic oil inflow, outflow direction without any problems, you can put the detection instrument installed in a certain position. Using this instrument, the position and nature of hydraulic transmission system faults can be diagnosed. When diagnosing faults, you need to set the fault detection steps in advance to check and diagnose possible fault locations. In addition, in fault diagnosis, we should pay special attention to the two aspects of temperature and hydraulic oil. The temperature must reach 50 degrees Celsius, otherwise, it will directly affect the test of hydraulic oil clarity. Hydraulic oil must meet the requirements of hydraulic transmission system, because different specifications of hydraulic oil have different clarity, and the clarity will directly affect the flow measurement.
duplicate
In the diagnosis of hydraulic transmission system failure, for small, easy to disassemble components will be used in the method of component interchange, such as check valve, balance valve and relief valve. Therefore, in the specific work, the hydraulic transmission system needs to be carefully observed, and then find abnormal components, and confirm the status of components, if normal, you can carry out component exchange work.
