G - type single screw pump product overview

The G-series single-screw pump is a new type of pump that operates according to the principle of reciprocating meshing. The main working parts are an eccentric screw (rotor) and fixed bushing (stator). Due to the special geometry of the two parts, a separate sealed cavity is formed, the medium has uniformly flowed in the axial direction, the internal flow rate is low, the volume remains constant and the pressure is stable, so that no eddy current and agitation are generated. Each stage of the pump output pressure of 0.6MPa, head 60m (water), for the transmission medium temperature below 80 ℃ (special requirements up to 150 ℃). Because the stator is made of a variety of elastic materials, so the pump for high-viscosity fluid transport and contains a rigid suspension of particulate media or fiber-containing transport, there are general pump can not do the characteristics. Its flow and speed are proportional to. Transmission can be used directly drive coupling, or the use of speed motor, V-belt, gearbox and other devices variable speed. This pump parts less compact, small size, easy maintenance, the rotor and the stator is the pump of wearing parts, simple structure, easy assembly and disassembly.

G single screw pump product features

G series single screw pump with self-priming ability, high suction; screw pump parts less compact, small size, easy maintenance, the rotor and the stator is a single screw pump wearing parts, simple structure, easy assembly and disassembly. It is a new type of pump that works according to the principle of positive displacement. Eccentric single screw pump The main working parts are an eccentric screw (rotor) and fixed bushing (stator). The use of non-toxic and tasteless edible rubber, the working temperature of up to 120 degrees Celsius, if the use of high temperature 120 degrees Celsius -350 degrees Celsius can contact with the unit. Due to the special geometry of the two parts at the beginning of the formation of a separate sealed cavity. The medium flows through the shaft evenly. The internal flow rate on behalf of the low, the volume remains unchanged. The pressure is stable and therefore the product does not swirl and stir. Each stage of the pump output pressure of 0.6MPa-1.2MPa, head 60m-120m (water), self-priming height is generally more than 3m. Can be used when the self-priming sewage pump products.

G single screw pump product advantages

1. compared with the centrifugal pump single screw pump without the need to install the valve, the flow is stable linear flow.
2. compared with the pneumatic diaphragm pump single screw pump can transport a variety of mixed impurities containing gas and solid particles or fiber media, but also transport a variety of corrosive substances.
3. compared with the gear pump, single screw pump can transport high viscosity material.
4. and the piston pump, diaphragm pump and gear pump is different, the screw pump can be used for pharmaceutical filling and measurement.

G-type single screw pump works

G series of single screw pump is a rotor-type positive displacement pump, which is dependent on the screw and the liner intermeshing in the suction chamber and discharge chamber to produce volume changes to transport the liquid. It is an internally closed, closed screw pump consisting of a bushing (stator) with a double-headed spiral cavity and a single-head screw (rotor) engaged with the stator cavity. When the input shaft drives the rotor around the stator center for the planetary rotation through the universal joint, the stator-rotor pair is continuously engaged to form a sealed chamber, and the volume of the sealed chamber is uniformly moved in a uniform direction, and the conveying medium is moved from the suction end - the rotor is conveyed to the extruded end, and the medium inhaled into the closed chamber flows through the stator without being disturbed and destroyed.

G-type single screw pump scope

G-type single screw pump use precautions

1. Single screw pump must be used for determining the direction of operation, shall not be reversed.
2. The single screw pump is strictly prohibited in the absence of medium air operation, so as not to damage the given.
3. Single screw pumps new installation or stop a few days after the single screw pump, can not start immediately, should be the first G-type single screw pump into the amount of oil, and then use the tube clamp after a few turn to start.
4. Single screw pump to send high viscosity or particles and corrosive media, the application of water or dissolved to wash, to prevent blocking, so as to avoid the next start difficult.
5. Single screw pump should be queued in winter to prevent freezing.
6. Single screw pump during the use of the bearing box should be regularly added lubricating oil, found that the shaft end of the seepage, the timely processing or exchange oil seal.
7. Single screw pump in the operation, such as the occurrence of abnormal circumstances, should immediately stop to check the cause, troubleshooting.
