How to quickly identify these faults of filter press

When using the filter press, we often encounter some working faults related to the filter press due to careless use or problems of the equipment itself, but how to quickly identify these faults?

Impact phenomenon of filter press

During the operation of the plate and frame filter press, the pressure of the liquid sometimes rises immediately, resulting in a pressure peak, which is much higher than the normal pressure. The pressure indicator exceeds the upper limit of the electric contact pressure gauge. It was initially considered to be a pressure gauge phenomenon. After many times of tracking, it was found that it occurred in the pressure maintaining state, and the pressure value was higher than the high pressure between 4 and 6Mpa, and much higher than the high pressure. Install a common pressure gauge on the connecting pipe between the feed inlet of the filter press and the feed pump, install a valve on the feed pipe, open and close the valve several times to control the flow, and readjust the working pressure of each filter.

Influence of pressure on hydraulic system

Adjust the use pressure of the filter press according to different plate and frame media and the head of the filter press pump. On the premise of ensuring the product quality, appropriately select the pressure of the filter press to protect each hydraulic component. Readjust the working pressure of the system. The working pressure of each filter press exceeds the updated working pressure, which is the main reason for the leakage caused by the damage of hydraulic components during the use of the filter press.

Effect of oil temperature

It is generally believed that the temperature of hydraulic oil is generally maintained at 10 ~ 65 ℃, and too high oil temperature can make the oil vapor evaporate, produce water vapor, and cause corrosion to the components in the machine; After cooling, it becomes some fine particles. After a long time, more particles cause them to converge into sediment, which is easy to block the oil filter in the hydraulic system and the small hole in the hydraulic valve, so that the hydraulic system can not work normally. At the same time, over time, it will cause the damage of some small pipelines.
