Shanghai hydraulic manufacturer supplies water-cooled hydraulic pump station

Shanghai hydraulic manufacturers supply water-cooled hydraulic pump stations/lift hydraulic stations, which have many advantages. However, due to the compact and delicate structure of oil pumps and valves, valve blockage and jamming may occur if not taken seriously during use, resulting in the failure of the entire system and causing unimaginable serious consequences. According to our company's statistics, over 70% of hydraulic station failures are caused by oil contamination. In the hydraulic station, we have designed several filters: coarse filtration at the oil pump suction port, fine filtration at the oil pump outlet, etc. In theory, oil that has undergone multiple filters should be relatively clean, but pollution can occur naturally in the system.

For example, metal particles generated by normal wear and tear of components such as pumps, directional valves, and oil cylinders.

2) Rubber particles generated by seal wear and detachment from oil filters, etc.

3) Inappropriate cleaning of components during production and maintenance processes is the main cause of pollution. This improper cleaning can cause fabric fibers (such as cotton yarn) to appear in the working oil, as well as sand and debris generated during mechanical processing, oxides on welding pipelines, slag, and residual materials after grinding. If these are not cleaned thoroughly, they can contaminate the oil.

4) Dust and particles in the air may also enter the system and cause pollution when the pump or valve is turned on.

5) During maintenance, dirt was mixed in due to careless operation.

The above reasons can cause faults such as clogged throttle holes and stuck valve cores. If these faults are not resolved in a timely manner, serious accidents may occur. Therefore, it is necessary to:

6) When loading and unloading components, they must be cleaned with kerosene or gasoline before replacement, and then dried with compressed air to avoid introducing dirt as much as possible.

7) Regularly check if the filter element is clogged, clean the coarse filter and replace the fine filter element in a timely manner.

8) When replacing the oil pipe, it must be removed and pickled after welding, cleaned thoroughly, and then reinstalled to prevent contamination of the entire hydraulic station oil by internal substances in the oil pipe.

9) The oil used in hydraulic systems should be regularly tested and replaced. Hydraulic oil should be sampled and tested every 3-6 months after the initial 200 hours of operation in hydraulic systems. And regular visual inspection should be conducted through windows or small samples to detect changes in chromaticity, turbidity, sediment, and odor. If the laboratory test fails, it should be replaced immediately. Even if the test is qualified after using for more than three years, the oil must be replaced.
