Supply screw

[Introduction of] Screw Screw Screw Screw http://www.botojd.com is engaging space volume change and move to rely formed screw pump to transport liquid or pressurized so that the rotary pump (see pump ). Screw screw divided by the number of single screw, twin screw and three screw pump. When the driving screw rotates, driven by its engagement driven screw rotates with the suction end of the screw engaging space chamber volume increases, the pressure is reduced. Liquid into engagement space volume in the pressure differential. When the maximum volume increased to form a sealed chamber, the liquid in a sealed chamber is continuously moved axially until the discharge end of the chamber. At this end of the screw engages the discharge chamber space volume gradually reduced, and the liquid is discharged. PCP works with gear pump is similar in structure but replaced with a screw gear. Table for the features and applications of various screw pump. Screw pump flow and pressure pulse is small, noise and vibration, there is self-absorption capacity, but more difficult to screw machine. The pump has a single suction and double suction two structures, but only a single suction single screw. The pump must be equipped with a safety valve (does not have to be equipped with a single screw), for some reason, such as to prevent blockage of the pump discharge pipe outlet pressure exceeds the allowable value and damage the pump or prime mover Botou Shield Machinery Co., Ltd. for your friendship recommendation: http://www.botojd.com/products-detail.asp?cpid=55 diaphragm coupling flexible coupling http://www.botojd.com/products-detail.asp?cpid=56
