1, the import and export Path: import and export of the principle filter diameter should not be less than the the matching pump inlet diameter, general unanimously agreed import pipeline.
2, Nominal pressure: the pressure rating of the f ilter determined in accordance with the highest pressure filter line may appear.bag filtration
3 hole mesh selection: main consideration the impurities particle size to be intercepted, according to media workflow process requirements. The particle size can be blocked by a variety of wire mesh check the following table "filter specifications.
4, the filter material: filter material generally select the connection process piping material for different service conditions may be considered to select the cast iron, carbon steel, low alloy steel or stainless steel backwash filter.
5, the filter resistance loss calculation
Water filter, and the nominal flow rate of the general calculation, the pressure loss is 0.52 ~ 1.2kpa
Suitable materials:
2, the weak corrosive material in the chemical, petrochemical production, such as: water, ammonia, oil, hydrocarbons, etc.;
4, the chemi cal production corrosive materials, such as caustic soda, soda ash, concentrated sulfuric acid, carbonic acid, acetic acid, esters, acids, etc.;
5, cryogenic refrigeration materials, such as: liquid methane, ammonia, liquid oxygen and a variety of refrigerant;
6, light food, pharmaceutical production materials hygiene requirements, such as: beer, beverages, dairy products, grain slurry pharmaceutical supplies.

7, the sealing material: Teflon, nitrile rubber, oil resistant asbestos rubber pipe filter characteristics: pipe filter is a small device to remove a small amount of solid particles in a liquid, the protection of compressors, pumps, instrumentation and other equipment work properly When the fluid enters the the set certain specification strainer cartridge, the impurity is blocked, while the clean filtrate from the filter outlet, when cleaning is required, as long as the removable cartridge is removed after treatment reload can, therefore, extremely easy to use and maintenance.
