Performance requirements, the top cover of the hair filter must be equipped with an exhaust valve. An observation hole should be provided on the top cover of the hair filter. ), the design pressure is not less than .times of the working pressure, and the test pressure is not less than .times of the design pressure.
), the total hole area should be no less than . times the cross-sectional area of the connecting pipe.
), the structure of the hair filter should be simple, reliable, flexible in assembly and disassembly, convenient for disassembly and washing, and good sealing.
), the size of the inlet and outlet of the hair filter should be consistent.
Key points for selection: Preferably use finished hair filters.
) The shell of the hair filter should be made of corrosion-resistant materials such as plastic, fiberglass, stainless steel or copper. If it is made of cast iron or carbon steel, it should be anti-corrosion treated and lined with anti-corrosion materials that must meet hygienic requirements. The working pressure of the shell should not be less than...
) The material of the hair filter should also be made of corrosion-resistant materials.
Important points for installation: It should be installed on the suction pipe of the circulating water pump and must be installed strictly in accordance with the flow direction of the hair filter. It must not be installed in the opposite direction.
), the hair filter must be installed on the foundation or the ground and must not rely on pipes to bear its weight.
), after installation, the tightness and pressure resistance test should be carried out together with the water suction pipe.

Product advantages: A filter is an object that can transmit requests or modify responses. It can pre-process the request before it arrives at r/ and can post-process the response after it leaves r/. So if you have several r/s that need to perform the same data conversion or page processing, you can write a filter class and associate the filter with the corresponding r/ in the deployment descriptor file (.). You can have a filter that operates on one or a group of r and zero or more filters that can filter one or more r .
A filter implements the .r .r interface and defines its three methods:
. (r): Called before the filter executes r to set the filter's configuration object.
． Called after the filter has executed r.
． (r).
