Characteristics of johnson screens:
Easy clearing
The narrowest part of the aperture comes at the top and the steady opening out from that point promotes easy clearing.
Lateral strength
Increases rapidly with the width of the profile and sufficient is needed to avoid the likelihood of the wedge wires being bent sideways and the accuracy of the slot being thereby lost.
Load carrying capacity or vertical strength
Increases rapidly with the depth of the profile and is needed to a greater degree than is lateral strength
Percentage open area
For any given aperture size this depends on the number of apertures per foot width of johnson screen. The wider the profile the fewer the apertures, and the less is open area - likewise the smaller the number of pressed wedge wires per foot, the greater the open area.
Wearing life
With abrasive materials the top surface of the profile becomes worn away and inevitably the aperture must increase. With a small angle of opening the increase is gradual, but with a large angle it is rapid. The apertures quickly reach the oversize limit and the working life is reduced.
The cnc stainless steel wedge wire johnson screen welding machine is special for welding wedge wire screen (mesh), water well screen (mesh), Vee-wire screen (mesh) for any filtering purpose in chemistry, mining industry and enviromental protection industry, etc.
We are a Chinese factory, we can produce new wedge wire wrap screen welding machine, we have patented technology, the machine energy consumption, stable performance, we provide one year warranty and overseas after-sales service.
Place of Origin: Hebei, China (Mainland) Brand Name: RENCHUN Model Number: HWJ1200 Usage: Liquid Filter Type: Filter Cylinder Material: stainless steel or carbon steel Hole Shape: wedge Filter Rating: 99% Thickness: Customize Size Length: 4000mm Width: Customize Size Tube Diameter: 600~1200mm Wire Range: 1.5~5mm Welding Speed: 6~20rpm Clearance of Slot: 6~20mm Precision of Slot: within 0.03mm Application for johnson screen made by johnson screen welding machine: deep well , water well , geothermal well , tube well , oil and gas exploration well , irrigation well , resident and industrial using well. Characteristics for johnson screen made by johnson screen welding machine: The johnson screen is made up of rods and warp. The rod can be round wire, triangular wire or trapezoid wire. The warp is triangular wire (V-shaped wire). Johnson screens have a structure and high open area, as well as accurate slot dimension. At the same time, johnson screen have heat-resisting, anti-corrosive, good machine capability, last long, safety and reliability and so on characteristics. It can be used in many kinds of medium filtering.
The WEDGE WIRE SCREEN welding machine features lower noise, less power consumption, steadiness, dustproof and safety. Mesh welding equipment is of advanced design .It adopts Japanese Mitsubishi E60 CNC control system. The motor for the feeding shaft and spindle are of Mitsubishi servo motor and the drivers are of Mitsubishi, Controlled by the Numeral control system, the servo motor drives the ball screw as well as the drawing disk which is mounted on the straight rail, so the slot clearance can be adjusted by touching the control screen without stopping the machine. features lower noise, less power consumption, steadiness, dustproof and safety.
