Single screw pump features working principle and selection parameters
[Asia pump network] screw pump performance characteristics: 1. The maximum suction height of 6 meters water column. 2 can be two-way rotation, two-way delivery (to be equipped with reverse stator). 3. Flexible installation. 4. Smooth, smooth, low noise, no pulse, no cutting. 5. Transmission medium temperature range -20 ℃ ~ +150 ℃. 6. Single screw pump parts, compact structure, small size, easy maintenance, the rotor and the stator is the pump wearing parts, simple structure, easy assembly and disassembly. Transmission can be directly driven by the coupling, or speed motor, V-belt, gearbox and other devices speed. Shanghai Equan Pump Co., Ltd. is manufacturing, design, production of single screw pump professional manufacturers. Different screw pump its specific use of the occasion is also different. How it works: G-type screw pump is an internal mesh closed screw pump, a rotor-type displacement pump. The main working part consists of a stator with a double-headed helical cavity and a single-headed helical screw that engages it in the stator bore, ie the rotor. When the input shaft drives the rotor through the universal joint to revolve around the stator, the stator and the rotor continuously mesh to form a sealed chamber, and the sealed chambers are uniformly and axially moved with constant volume. The input medium flows from the suction end to the stator-rotor The media delivered to the press-out end and fed to the sealed chamber flows through the stator without being agitated and destroyed. Therefore, it is possible to convey mediums and viscous liquids containing hard abrasive impurities and solid particles. G-type single-screw pump is based on the principle of turning to engage the new volume of positive displacement pump. The main working parts are eccentric screw (rotor) and fixed bushings (stator). Due to the special geometrical beginning of the part, separate sealing cavities are formed. Medium by the axial uniform flow. Low internal flow rate, the volume remains unchanged. The pressure is stable and therefore will not vortex and agitate the product. Single screw pump is widely used in various industries to transport various types of media, continuous operation of constant pressure, no pulsation, no damage to the media delivery, by adjusting the speed to change the flow in order to achieve the purpose of measurement.

performance parameters are tested at room temperature water test data; 2, for different media, different speed, performance parameters will change, the flow value and concentration, viscosity is inversely proportional to the speed 3, the user must be based on the requirements of the delivery of media, the selection principle to choose the type of pump, or in consultation with the company's technical department to determine the type of pump. 4, for the form of coal-water pump drive for the gear speed control electromagnetic speed motor or mechanical stepless variable speed motor, the flow rate with variable speed stepless adjustable.
