Rotary Sieve Screens
Rotary Sieve Screens are manufactured by v-wire running radially on the outside surface of the screen cylinder or running axially on the inside of the cylinder. According to the relationship of wedge wire and the supporting rod, there are four flow directions as bellow (see WWSC-2 to WWSC-5). Each connection point of wedge wire to the support rod is welded to increase the strength and durability. Wedge screen cylinders can be used as water well screen, rotary screen and nozzle screens for separating solids from liquids.
Application of the Rotary Sieve Screens
Rotary Sieve Screens is the most popular pipe that uesd in the water well and oil well nowadays.It can be prevent the sand and other granules effective.With the same open area and conditions to other water well pipe,wedge wire pipe can let water entering screen at the slowest speed.And also the longest life then others at the same material.Because the Vee shaped profile wire will not be blocking and have great pressure,wedge wire water well screen becoming the most economical pipe.
Advantages of the Rotary Sieve Screens
•High mechanical strength to withstand greater pressure difference.
•The homogeneous filtration gap forms a relatively homogeneous cake to facilitate backwash regeneration.
•Wedged gap can improve backwash regeneration capacity.
•Pressure, temperature, aging and corrosion—resistant, suitable for all kinds of fluids.
•Metal wedged wire mesh is adopted as filter element and has the advantages, such as, high mechanical strength, high g reater pressure difference, easy cleaning, and regeneration. Al most two—dimensional filter mesh have no par— ticle packing dead space, the wedged gap can gather energy when backwashing, with good resuIt.
