Single screw pump technical parameters
Single-Screw pump is a rotor type positive displacement pump, this pump has a very good intake performance, but also has good self-priming capabilities and other advantages, so the use of such pump equipment by the user's favorite. For those who want to understand single screw pump users, single screw pump parameters and other information is to understand the single screw pump is very important content, so this is to master the content. Single screw pump technical parameters Screw pump technical parameters usually refers to the flow, excluding pressure, suction pressure, speed, pump input power (shaft power), media characteristics, medium temperature and medium viscosity. Flow rate and medium viscosity by the impact of medium viscosity also affects the pump input power, the choice of speed and medium viscosity has a great relationship, but also affect the suction pump performance. The design of the pump must consider the relationship between these parameters. 1, the flow rate of flow refers to the pump in the unit of time to send the media or the pump per revolution excluded by the media. Volume flow Q, Qz mass flow said that when the rotor rotates a week, the media along the axial movement of the stator a lead T, so the rotor rotates a week, the volume of the pump transport medium 4eDT. 2, speed screw pump to work reliably must limit the speed. The main factors affecting the selection speed are as follows: Suction performance. The higher the pump speed, the greater the flow, the speed not only affects the pumping into the cavity of the loss, and when the speed increased to a certain extent, it will happen in the suction under pressure medium too late to enter or too full Open the sealed chamber, suction into the geometric height, the medium in the suction pipe frictional resistance and the characteristics of the medium and temperature are limited to the pump speed agreed. 3, the wear of the medium The abrasion of the medium has a direct impact on the wear resistance of the rotor and the stator, which affects the service life, the more "bad" media (here only refers to the magazine, lubrication and activity, etc.) The rotor and stator must wear more easily, and the higher the speed of the pump, the faster the wear. Therefore, the speed of the pump is also limited by the abrasion of the transport medium and the like. Through the above simple introduction of the relevant technical parameters of single screw pump, single screw pump technical parameters we have a more preliminary concept, from historical experience we can find the single screw pump technical parameters for the use of single screw pump, with the single There is still a lot of places where the use of screw pumps is expanding. There are still many places that need to work hard on the research and application of single-screw pumps. This not only requires the wisdom of experts and scholars, but also requires the user's suggestions and opinions. This article is copyrighted industry interconnect (Xiamen) Co., Ltd.
