Basket Strainer Ductile Iron Filter Manufacture
Shandong Rinborn Machinery Technology Co.,Ltd, with professional factory, is one of the leading China BS cast iron gate valve manufacturers, we are able to offer you cheap BS cast iron gate valve. Welcome to wholesale products from us.
Basket filter is used for oil or other liquid pipelines, filtering the debris in the pipeline, the filter hole area is 2-3 times larger than the diameter pipe area, far more than the Y, T filter area. Filter accuracy in the filter belongs to a filter with the best accuracy, the filter structure is different from other filters, because the shape is like a basket, so the name basket filter.
The basket filter is mainly composed of nozzle, barrel, filter basket, flange, flange cover and fastener. Installed on the pipeline can remove large solid impurities in the fluid, so that the machine equipment (including compressors, pumps, etc.), instruments can work and operate normally, to stabilize the process and ensure the role of safe production.
Blue filter is a small device to remove a small amount of solid particles in the liquid, which can protect the normal work of compressors, pumps, meters and other, when the fluid enters the filter bucket with a certain specification of the filter screen, its impurities are blocked, and the clean filtrate is discharged by the filter outlet, when it needs to be cleaned, as long as the detachable filter bucket is removed, and the process is re-loaded, so, Easy 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 pump inlet or other parts of the system pipeline, it can extend the service life of the pump and other equipment, and ensure the safety of the entire system.
1. Suitable materials:
a, chemical, petrochemical production of weakly corrosive materials, such as: water, ammonia, oil, hydrocarbons;
b, chemical production of corrosive materials, 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, light industrial food, pharmaceutical production of hygiene requirements of the material, such as: beer, beverages, dairy products, food pulp and medical supplies.
2, working temperature: -80℃ – +450℃
3, nominal diameter: DN15-DN600
4, nominal pressure: PN1.0-5.0mpa
5, flange standard: HG20592-97 (can also be manufactured according to user requirements)
6, shell material: A3, 304, 304L, 316, 316L
7, sealing material: polytetrafluoroethylene, nitrile rubber, oil-resistant asbestos rubber
8. Manufacturing testing standard: HGJ532-91IN AND OUT DIAMETER:
In principle, the inlet and outlet diameter of the filter should not be smaller than the inlet diameter of the matching pump, generally consistent with the inlet pipe caliber.
2, nominal pressure:
Determine the pressure level of the filter according to the highest possible pressure in the filter line.
3, the selection of the number of holes:
The main consideration is the particle size of the impurities to be intercepted, according to the process requirements of the medium process. The particle size of various specifications can be intercepted by the screen check the table “filter specifications.
