With the development of science and technology, the development of precision instruments has become more and more rapid, and the application of precision compressed air filters has become more and more extensive. The compressed air precision filter is an indispensable device on the pipeline of the conveying medium. It is usually installed at the inlet end of a pressure reducing valve, a pressure relief valve, a fixed water level valve or other equipment to eliminate impurities in the medium to protect the valve and Normal use of equipment. However, the installation position of the precision compressed air filter has certain requirements, let's talk about it in detail below.
The installation position of the precision compressed air filter:
(1) In general low-pressure devices with pressures below 140kg/cm2, only suction filters are usually installed, but return filters and air filters should also be installed.
(2) In general medium and high pressure liquid installations with a pressure above 140kg/cm2, a return filter is generally used to control the pollution concentration. But when there are special requirements for reliability, a high-pressure pipeline filter should be used together.
(3) In order to increase the reliability of electromagnetic proportional control valve or small flow regulating valve, a terminal filter should be installed.
(4) When using servo valves, efforts should be made to reduce the pollution concentration of the system. Therefore, high pressure and return filters should be used together; for large capacity, a circulation filter should be installed, and a terminal filter should be installed on the auxiliary pipeline.
The above is the installation position of the precision compressed air filter, I hope it will be helpful to everyone.
