Single screw pump structure advantages Single screw pump is a new type of liquid conveying machinery, with simple structure, safe and reliable work, easy maintenance, liquid continuous and uniform, the pressure stability and so on. Single-screw pumps offer the following benefits: They are less sensitive to ingress of gases and contaminants than other rotary pumps; they offer a wide range of fluid types and viscosities; because of the low inertia of rotating parts in single-screw pumps, High speed; inhalation performance, with self-absorption capacity; flow uniform and continuous, small vibration, low noise; wide pressure and flow range. Pressure of about 3.4-340 kgf / cm 2, the flow rate of up to 18,600 cm3 / min; solid structure, easy installation and maintenance. Adapt to a wide range, can transport all mobile media or even non-mobile materials. Flow, pressure stability, no pulse. Variable speed can change the output flow, can be used as measurement dosing. Inhalation, work noise, no leakage, no temperature rise. The disadvantage of a single screw pump is that the screw machining and assembly requirements are higher; the performance of the pump is sensitive to changes in the viscosity of the liquid. Each revolution of the single screw pump, the liquid in the sealed chamber is pushed forward by a pitch. As the screw rotates continuously, the liquid spirally presses from one sealed chamber to the other sealed chamber and finally out of the pump body. Single screw pump is a single screw pump, its main working parts are eccentric screw spiral (referred to as the rotor) and the inner surface of the double helical screw bush (called stator). Single-screw pump its working principle is that when the motor drives the pump shaft rotation, the screw on one hand around its own axis of rotation, on the other hand it rolls along the inner surface of the sleeve, thus forming a sealed pump chamber.
