What is the V-shape Wire Screen? V wire screen is also called wedge wire screen, Johnson v wire water well screen and stainless steel filter tube, which is widely used in the oil, gas, water well and sand control industry in the worldwide. Its position in the well industry is especially prominent, and it is the most popular type of filter elements in various liquid filtration process. The full-welded v wire screen adopts a full-wound welding production process, and is welded with a special trapezoidal wire winding on a set of support wires arranged in a circumferential arrangement. The whole welding ensures the strict continuous integrity of the product, which makes it form an ideal gap size and has the capability of bearing high pressure in maximum quantity. The material of the v wire screen mainly includes the stainless steel 304, 316 and 316L, Monel copper-nickel alloy, low carbon steel and thermoplastic material, polyvinyl chloride and acrylonitrile-butadiene-styren...

Hydraulic Filter Elements Pleated Stainless Steel Wire Mesh Hydraulic Filter Element Product Introduction: This series of filter elements are installed into the oil process parts of the press filtration, to remove the mental powder and other mechanical impurities in the press system,and that can control the pollution degree of the working medium, and thus to keep the oil process clean, and extend the system working life. Product Code: Metal Filter. Material: Hydraulic filter elements is made of stainless steel woven wire mesh or sintered wire mesh. Features: This kind of filter elements is made from single-layer or multi-layer woven wire mesh or sintered wire mesh. Hydraulic filter elements have different layer numbers of wire mesh and different mesh counts depending on the work and application conditions. The pressure applied is high and the surface has a straight line and no burr. Hydraulic filter elements for replacement have a refined filtration accuracy and long service lif...

Filter accuracy  1.Definition of nominal accuracy: Based on a certain weight removal percentage of all particles greater than or equal to a given size, the controversial micron value specified by the filter manufacturer. It has almost no good details and no reproducibility. Controversial micron accuracy 1). Designated by the manufacturer 2). Remove weight percentage 3). Variable, non-reproducible downstream fluid quality 4). Non-fixed hole structure 2.Absolute accuracy The diameter of the largest rigid spherical particle that is capable of passing through the filter under specified test conditions. It is the hallmark of the largest opening in the filter element.

Filtration Removal of contaminants from fluids (liquids or gases) using porous media Micron 1 micron (um) =10－6 m ＝10－3 mm= 3.9×10 -5 inch Three filtering mechanisms 1.Direct interception Basic filtration mechanism in liquid The essence is a sieving effect, mechanical interception of particles For example: a simple screen can intercept the size, particles larger than their pore size. When the particles are larger than the flow channel aperture, they are removed by the structure. The dirt holding capacity can be improved by the curved structure Screen does not have this effect Particles smaller than the pore size can also be intercepted by bridging Irregularly shaped particles / directionality Multiple particles hit the same filter at the same time 1). Irregular shape bridge 2). Multiple small particles 2.Inertial impact Auxiliary interception method for particles smaller than the pore size of the filter material Fluid-carrying particles ha...
