Introduction Of Screw Pump

Screw pump, also known as "screw pump", "Archimedes screw pump". A pump that utilizes the rotation of spiral blades to cause water to spiral up along the axial direction. Composed of shaft, spiral blade, and shell. When pumping water, place the pump diagonally in the water, so that the inclination angle of the pump spindle is less than the inclination angle of the spiral blade, and the lower end of the spiral blade is in contact with the water. When the prime mover drives the screw pump shaft to rotate through a variable speed device, water enters the blades and rises along the spiral flow channel until it flows out. Simple structure, easy manufacturing, high flow rate, low head loss, high efficiency, easy maintenance and repair, but low lift, low speed, requiring a variable speed device. It is commonly used for irrigation, drainage, and sewage, sludge, and other purposes. China began using it in the 1970s.
