Single Screw

An overview incremental rotary positive displacement pumps belong. Is a high-precision mechanical products, it is simple and reasonable structure, allow high speed, small pressure pulsation, low noise, balanced and reliable work, self-absorption, and high volumetric efficiency. At home and abroad have very broad application prospects. It takes advantage of the screw is rotated continuously to seal liquid inlet spiral space to move in the axial direction at the outlet. Thus, a ratio gear pumps, piston pumps and centrifugal pumps superior properties. Particularly suitable for transporting liquid oils and high viscosity. Liquids and emulsions, syrups, liquid, polymer and other non-lubricating high viscosity; widely used in the transport of oil and various petroleum products such as crude oil, heavy oil, light oil, lubricating oil, fuel oil, asphalt, grease, vegetable oil . Thus, in refineries, petrochemical plants, oil tanker terminals, asphalt storage, power hydraulic equipment, ships and light industry, food industry and other sectors, has been widely applied. Two pump body, the structure of both horizontal and vertical, with random safety valve, there are two kinds of insulation and without heat. High flow pump, the liner is a separate part fixed to the pump body. Structure is vertical, double suction, with random safety valve. All mechanical seal, to ensure the sealing performance under high temperature conditions.
