First,The common reasons for the large pressure difference in the operation of the security filter are as follows:
1. There are a lot of impurities in the filter cartridge of the security filter, which may be due to the accumulation of excessive impurities on the surface of the filter element, which will block the filter element or damage it, resulting in a large operating pressure difference of the security filter.
2.The working pressure of the security filter exceeds the specified value, and each device can only work within a reasonable range. Once the working pressure exceeds the bearing range of the equipment itself, the pressure difference will be too large.
3.The security filter element or the surface of the tank is fouled. If the water quality environment is poor and the organic compounds such as calcium carbonate in the sewage are high, long-term filtration but no cleaning will directly lead to scaling on the surface of the tank, which will also cause the pressure difference of the filter to increase.
4.The pressure gauge of the security filter is damaged. The pressure gauge is generally installed on the top of the upper cover of the filter tank. If the pressure gauge is seriously damaged, some deviations will occur. An excessive filter differential pressure has occurred.
Second,the solution to the large difference in the operation of the security filter
1.Check the pollution degree of the filter, take out the filter element in time, and clean it. Choose an appropriate cleaning method, light pollution can be physical cleaning method, if it is heavy pollution, you need to add chemicals, and use chemical cleaning method to soak and clean.
2.Check the working pressure of the equipment and adjust the working pressure to a reasonable range. If the user has a high demand for permeate water, a security filter with a higher permeate water volume is required.
3.Use the measuring equipment to test the pressure gauge, if any damage is found, replace the pressure gauge with a new one immediately.
