[Basket type filter]——(Basket type filter), mainly composed of connection pipe, main pipe, filter basket, flange, flange cover and fasteners. When the liquid enters the filter basket through the main pipe, the solid impurity particles are blocked in the filter basket, and the clean fluid passes through the filter basket and is discharged from the filter outlet. When cleaning is needed, unscrew the screw plug at the bottom of the main pipe, drain the fluid, remove the flange cover, and reinstall it after cleaning. Therefore, it is extremely convenient to use and maintain.
The basket filter is used on oil or other liquid pipelines to filter debris in the pipeline. The area of the filter hole is greater than 2-3 times the area of the diameter pipe. Far exceeds the filtration area of Y-type and T-type filters. The structure of the filter is different from other filters, because it is shaped like a basket, it is called a basket filter.
Basket filter is mainly composed of connecting pipe, cylinder, filter basket, flange, flange cover and fasteners. Installed on the pipeline can remove the larger solid impurities in the fluid, so that the machinery and equipment (including compressors, pumps, etc.) and instruments can work and run normally, achieve a stable process, and ensure safe production.
The blue filter is a small device that removes a small amount of solid particles in the liquid. It can protect the normal operation of the compressor, pump, instrument and others. When the fluid enters the filter barrel with a certain specification filter screen, its impurities are blocked and clean The filtrate is discharged from the outlet of the filter. When cleaning is needed, just take out the detachable filter barrel and reload it after treatment. Therefore, it is extremely convenient to use and maintain. It has been widely used in petroleum, chemical, pharmaceutical, food, environmental protection and other industries. If it is installed in series at the inlet of the pump or other parts of the system pipeline, the service life of the pump and other equipment can be prolonged, and the safety of the entire system can be guaranteed.
Suitable materials:
a. Weakly corrosive materials in chemical and petrochemical production, such as water, ammonia, oil, hydrocarbons, etc.;
b. Corrosive materials in chemical production, such as caustic soda, soda ash, concentrated sulfuric acid, carbonic acid, acetic acid, ester acid, etc.;
c. Low-temperature materials in refrigeration, such as liquid methane, liquid ammonia, liquid oxygen and various refrigerants;
d. Materials with sanitary requirements in the production of light industrial foods and pharmaceuticals, such as beer, beverages, dairy products, grain slurry medical supplies, etc.
2. Working temperature: -80℃—+450℃
3. Nominal diameter: DN15—DN600
4. Nominal pressure: PN1.0—5.0Mpa
5. Flange standard: HG20592-97 (also can be manufactured according to user requirements)
6. Shell material: A3, 304, 304L, 316, 316L
7. Sealing material: PTFE, nitrile rubber, oil-resistant asbestos rubber
8. Manufacturing inspection standard: HGJ532-91
Selection principle
1. Import and export path:
In principle, the inlet and outlet diameter of the filter should not be smaller than the inlet diameter of the matching pump, and generally the same as the inlet pipe diameter.
2. Nominal pressure:
Determine the pressure level of the filter according to the highest pressure that may appear in the filter line.
3. Selection of the number of holes:
The main consideration is the particle size of impurities to be intercepted, which is determined according to the requirements of the medium process. Check the filter specifications in the table below for the particle size that can be intercepted by various specifications of screens.
