Stainless Steel Johnson Wedge Wire Screens , Johnson Water Pump Screen Filter Pipe
Johnson screen is manufactured by a "V" or wedge shaped wire around an internal array of longitudinal support rods. Each intersecting point of these wires is fusion welded. The "V" or wedge shaped profile wire wraps around support rods over the full length of the screen creating a continuous slot opening, hence the screen allows water (oil) to enter your well freely in ample quantities, while at the same time keeps the majority of sand and gravel out of the well
Advantages of stainless steel johnson screen for filtration
Continuous slot: opening significantly increases the available open area, providing greater access to the water-bearing zone.
Non-clogging: "V" shaped or wedge shaped profile wire, avoids clogging, is self-cleaning and ensures an uninterrupted flow. Sand grains make only two point contact and don't wedge in the screen's inwardly enlarging slot.
Large open area: this allows more water to enter at much lesser frictional head loss and the efficiency of well is improved appreciably.
Application of stainless steel johnson screen for filtration
The strainer is a kind of filtered water tubing with the perforation .it can use with the deep well pump, dive the water pump, also may use in the water-treating equipment, the environmental protection, the sea water transforms into the industrial water and life use water desalination treatment, running water treatment, water softening treatment, the petroleum industry: The petroleum production.
