When using a filter press, due to careless use or problems with the equipment itself, we often encounter some working failures related to the filter press, but how to quickly identify these failures?
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 that is much higher than the normal pressure. The pressure indicator exceeds the upper limit of the electric contact pressure gauge. It was originally considered a pressure gauge phenomenon. After many follow-ups, it was found that it occurred in a pressure-holding state, and the pressure value was higher than the high pressure between 4 and 6 MPa, and much higher than the high pressure. Install an ordinary pressure gauge on the connecting pipe between the feed port of the filter press and the feed pump, install a valve on the feed pipe, open and close the valve multiple times to control the flow, and readjust each filter The working pressure is pressed.
Influence of pressure on hydraulic system
Adjust the working pressure of the filter press according to different plate and frame media and the head of the filter press pump. Under the premise of ensuring product quality, appropriately select the pressure of the filter press to protect each hydraulic original. Re-adjust 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 of hydraulic components caused by the damage of the hydraulic components during the use of the filter press.
Influence of oil temperature
It is generally believed that the temperature of hydraulic oil is generally maintained at 10～65℃. Excessive oil temperature can vaporize the oil, produce water vapor, and cause corrosion to the original parts in the machine; it will become some fine particles after cooling, which takes a long time. As a result of a large number of particles, it is easy to block the oil filter and the small holes in the hydraulic valve in the hydraulic system, which will cause the hydraulic system to not work normally. At the same time, it will cause some small pipelines to be damaged over time. damaged.
