Screw screw-GS Series SURVEY:

    Hao Star GS series single screw pump, also known as screw: Stainless steel screw, eccentric screw pump, pump, pump thick, volumetric pumps, slurry pumps, rotary gear together is based on the principle of a new type of positive displacement pump types, the main work member is eccentric screw (rotor) and a fixed bush (stator). Because of the special geometry of the part, respectively, form a single seal cavity, the medium uniformly implemented by an axial flow, the internal flow is low, the volume remains constant, the pressure is stable, and thus will not produce eddy currents and agitation. Each level of the pump output pressure 0.3 ~ 0.6Mpa lift 20 ~ 60m (Shimizu), self-priming height is generally 1 ~ 3m or more. Because the stator choose a variety of flexible material, so this pump for high viscosity fluids containing hard floating transport of particulate media or contain fiber transmission medium, a general kind of pump characteristics can not do. Proportional to the speed of its flow. Turn generally use direct drive coupling, or by motor, or belt, and devices such as variable speed gearbox. This pump Advantages: 1, flow, pressure stability, no pulse. 2, variable speed can change the output flows, can be used as metering dosing. 3, the suction ability, work noise, no leakage, no temperature rise. Suction performance, pressure, flow stability.

GS Series Screw it works:

  Hao Star GS-type single-screw pump is an internal gear eccentric rotary positive displacement pump, the pump main components: a single-head screw rotor and an elastic material is usually made with a pun helix stator when the rotor is scheduled for type wound stator cavity axis as the planet rotates, formed between the rotor and stator enclosed wrists produce displacement along a helical rotor; therefore it will be a continuous medium, the average rate, the volume and constant pressure from the inlet to the end based on this characteristic, single screw pump is particularly suitable for the work of the following conditions. Requires delivery pressure is stable, the inherent structure of the media does not love destroyed, the selection of a single screw conveyor is ideal. Single screw has been widely used in foreign countries, most countries said single screw as "MONOPUMPS Mono Pump", the German also known as "eccentric rotor pump." Because of its excellent performance in recent years in the country is rapidly expanding range of applications. It works by a special helical surface elastic stator cavity has a large lead large teeth meshing high rotor in the stator cavity sealing lines will constitute a continuous suction chamber and the pressure of the chamber separated from the rotor turns cavity contiguous to the discharge direction, so that the material is sucked and discharged continuously. Its greatest feature is the adaptability of the medium, smooth flow, pressure pulsation, self-absorption capacity, which is any other kind of pump can not replace. Our domestic and foreign production of single-screw products, made a comprehensive investigation, to win public long, for their continuous product innovation. Currently our factory's products have an independent system, the pressure is 0.3 ~ 0.6MPa, also based on the majority of users of different single screw special needs and customization.

Compared with other types of pumps:

And centrifugal pumps compared to single screw not need to install the valve, and flow is stable linear flow.
And piston, single screw pump has better self-absorption capacity, suction height up to 8.5 m water column.
And diaphragm pumps, single screw pump can transport all kinds of mixed impurities containing medium of gas and solid particles or fibers, transport all kinds of corrosive substances.
Compared with gear pump, single screw pump can transport high-viscosity material.
Piston pump, diaphragm pump and gear pump, single screw pump can be used in pharmaceutical filling and measurement.
