Screw conveying pump

A screw conveyor is a machine that uses a motor to drive a screw to rotate and push materials to achieve the purpose of conveying. It can be transported horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. Screw conveyors are divided into two types: shafted screw conveyors and shaftless screw conveyors in terms of conveying forms, and are divided into U-shaped screw conveyors and tubular screw conveyors in appearance. Shafted screw conveyors are suitable for non-viscous dry powder. Materials and small granular materials. (For example: cement, fly ash, lime, grain, etc.) and the shaftless screw conveyor is suitable for conveying viscous and easily entangled materials. (For example: sludge, biomass, garbage, etc.) The working principle of the screw conveyor is that the rotating screw blade pushes the material for the screw conveyor to transport, so that the material does not rotate with the screw conveyor blade The force is the weight of the material and the The frictional resistance of the screw conveyor casing to the material. The spiral blade welded on the rotating shaft of the screw conveyor, the blade surface type has solid surface type, belt type surface type, blade surface type and other types according to the different conveying materials. The screw shaft of the screw conveyor has a thrust bearing at the end of the material moving direction to give the screw axial reaction force with the material. When the length of the machine is long, an intermediate hanging bearing should be added. 1. The machine adopts thickened steel plate, and the high-quality steel is durable; 2. The purple core all-copper motor is used, and the motor is resistant to high temperature and not easy to burn; 3. The surface is made of baking paint, with good surface finish, easy to scrub, moisture-proof and fire-proof; 4. Long service life, compact structure, small return clearance and high precision
