Screw pump working principle

[Asia Fluid Network News] Screw pump is a self-priming capability, uniform flow, small vibration, low noise, solid structure, easy installation. As China's industrial areas such as its growing demand, screw pump attracted more and more attention. Understanding and analyzing the working principle of the screw pump has become the first choice for many users to purchase and use the products. Screw pump works Each product has its own unique place, screw pump is a unique structure of the volume pump, which is mainly driven by the motor and reducer, and even the shaft and connecting rod box, stator and rotor and other components . When the screw pump is working, the rotor is driven by a motor to make planets rotate in the stator. The cooperating rotor and the elastic bushing of the stator form several non-communicating sealed cavities. Due to the rotation of the rotor, the sealed cavity is axially moved from the suction end to the discharge end, and the medium is continuously delivered from the suction end to the discharge end within the cavity. A screw pump is a rotary pump that uses screws to engage and discharge liquid. Screw pump rotor by the active screw (which can be one or two or three) and driven screw composition. The driving screw and the driven screw rotate in the opposite direction, and the threads mesh with each other. The fluid enters from the suction inlet and is pushed forward by the screw shaft to pressurize the discharge outlet. This pump is suitable for high pressure, small flow. Screw pump in the use of need to pay attention to many places, the attention of these matters, just like the spring planting, only concerned about more details to wait for the harvest season. Screw pump assembly should be carefully cleaned screw parts, inspection, damaged parts should be replaced, check the seal is damaged, the cavity filled with grease, mechanical seal installation should be careful, the friction end face should be cleaned and coated with lubrication Grease, install the stator, with lubricant smear rotor, stator cavity surface, is conducive to the stator installation.
