Basket Strainers/Bucket Strainers

What is a basket strainer?

Basket strainer, also known as barrel strainer, bucket strainer, is mainly composed of connecting pipe, main pipe, strainer basket, flange, flange cover and fasteners. When the liquid enters the strainer basket through the main pipe, the solid impurity particles are blocked in the strainer basket, and the clean fluid is discharged from the strainer outlet through the strainer basket. 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 very convenient to use and maintain.

Basket strainer is a small equipment for removing a small amount of solid particles in liquid, which can protect the normal operation of the equipment. When the fluid enters the strainer cartridge equipped with a certain specification of strainer screen, its impurities are blocked, and the clean filtrate is discharged from the strainer outlet. When it needs to be cleaned, just take out the removable strainer cartridge and reload it after treatment. Therefore, it is very convenient for use and maintenance.

Classification of basket strainers

1. Air strainer
Make the polluted air clean to the state required by production and life, that is, make the air reach a certain cleanliness.
2. Liquid strainer
Make the contaminated liquid clean to the state required by production and life, that is, make the liquid reach a certain cleanliness.
In fact, there are many kinds of strainers, such as laminated strainer, sand strainer, carbon strainer, etc. the main principle is to use the pore diameter of the strainer medium to intercept substances larger than the pore diameter of the medium. Of course, some strainer media also have special effects such as adsorption. Most strainer backwashing is not so troublesome. As long as clean water is introduced into the medium in the backwashing strainer from one end of the strainered water, a good backwashing effect can be achieved. This type of valve shall be installed horizontally in the pipeline.
3. Pipe strainer
It is a small equipment for removing a small amount of solid particles in the liquid, which can protect the normal operation of compressors, pumps, instruments and other equipment. When the medium enters the basket strainer, the strainered medium meets the industrial standard. The specific media are different, and the strainer element specifications are different. The strainer produced by the company has the advantages of compact structure, large strainering capacity, small pressure loss, wide application range, convenient maintenance and low price. Its main applicable materials are:
Weakly corrosive materials in chemical and petrochemical production, such as water, oil products, ammonia, hydrocarbons, etc.
Corrosive materials in chemical production, such as caustic soda, soda ash, concentrated and dilute sulfuric acid, carbonic acid, aldehyde acid, etc.
Low temperature materials in refrigeration, such as liquid methane, liquid ammonia, liquid oxygen and various refrigerants.
Materials with hygienic requirements in food and pharmaceutical production, such as beer, beverage, dairy products, syrup, etc.
Y-type strainer (water strainer) belongs to the pipeline coarse strainer series, which can also be used for the filtration of large particles in gas or other media. When installed on the pipeline, it can remove large solid impurities in the fluid, so that the machinery and equipment (including compressor, pump, etc.) and instruments can work and operate normally, so as to stabilize the process and ensure safe production. The Y-type strainer (water strainer) produced by the company can be customized according to the specific requirements of customers (special pressure and special diameter). Y-type strainer (water strainer) has the advantages of simple manufacture, convenient installation and cleaning, large pollution capacity and so on.
Selection principle of basket strainer
Manufacturing standard of basket strainer for pipeline JB/7538
1. Inlet and outlet diameter
In principle, the inlet and outlet diameter of the strainer shall not be less than the inlet diameter of the matched pump, which is generally consistent with the diameter of the inlet pipeline.
2. Nominal pressure
Determine the pressure level of the strainer according to the maximum pressure that may appear in the strainer pipeline.
3. Selection of hole number
It mainly considers the particle size of impurities to be intercepted, which is determined according to the process requirements of medium process. The particle size that can be intercepted by various specifications of screen can be found in the following table “screen specifications”.

China basket strainer manufacturer supplies basket strainer for industrial use, in kinds of materials such as carbon steel, stainless steel, alloy steel, etc.
