Detailed description of Basket filter
Datetime: Hits:
Basket filter for oil or other liquid pipeline, sundries in the filter tube, filter hole area than size tube area is greater than 2 to 3 times. Far more than Y type, T type filters filter area. Basket Filter in the filter precision belongs to a kind of the best filter, precision filter structure is different from other filters, shaped like a basket, so the basket strainer.
Basket strainer is mainly composed of takeover, barrel, filter basket, flange, flange cover and fasteners, etc. Installed on the pipeline to remove large solid impurity in the fluid, the machinery and equipment (including compressor, pump, etc.), the instrument can work normally and operation, to achieve stable process, the role of guaranteeing production safety.
Basket filter is to remove a small amount of solid particles in the liquid of small devices, can protect the compressor, pump, instruments and other work, when fluid into the has certain specifications of the mesh filter barrels, the impurity is blocked, and clean the filtrate by filter outlet, when need to wash, just remove the removable filter barrels, after processing to reload the can, therefore, is very convenient in operation and maintenance. At present has been widely used in petroleum, chemical, pharmaceutical, food industry, environment protection, etc. If the string of the installed in the entrance of the pump or other parts of the pipeline system, then can prolong the service life of pump and other equipment, and can guarantee the safety of the whole system..
Cleaning methods: when the need to wash, Unscrew the bottom of the head screw, net fluid, remove the flange cover, to reload after cleaning.
Pressure testing and detection: filter pressure of hydrostatic test pressure of 1.5 times for their design, the holding time for 30 minutes, to ensure no seepage and deformation phenomenon.
Basket filter selection principle:
1, import and export size: in principle, the import and export of the filter size should not be less than the import of matching pump size, generally consistent with imported pipe diameter.
2, nominal pressure: termini in accordance with the highest pressure filter line possible filter pressure rating.
3, the number of hole mesh: the main consideration to intercept impurities particle size, according to the medium flow process requirement. All kinds of wire mesh can intercept the particle size of the check table below "mesh specifications".
Important technical parameters:
1, material:
A, weak corrosively medium for chemical, petrochemical production, such as: water, ammonia, oil, hydrocarbon, etc;
B, chemical production of corrosive materials, such as caustic soda, soda ash, thick dilute sculptures acid, carbonic acid, acetic acid, ester, acid, etc.;
C, cooling, the low temperature materials, such as: liquid methane, ammonia, oxygen, and various refrigerants;
D, light industry, food, pharmaceutical materials with health requirements in production, such as: beer, beverage, dairy products, syrup medical supplies, etc.
2, work temperature: 80 ℃ to + 450 ℃.
3, nominal diameter:15 - DN600.
4, nominal pressure: PN1.0-5.0 Mpa.
5, flange standard: HG20592-97 (also can be made according to user requirements)
6, shell material: A3, 304 l, 304 l, 304, 304.
7, sealing materials: Teflon, nitrile rubber rubber, oil resistant rubber asbestos.
8, manufacturing testing standard: HGJ532-9.
