Product introduction
Hopper screw pump is based on G series single screw pump to add hopper, connecting rod shaft to add screw propeller, suitable for liquid or paste material that can not flow by itself, and can be equipped with agitator to prevent material precipitation. When the material concentration is high, adding a large funnel that can be extruded and crushed can prevent clogging. Propeller screw pumps can be equipped with various drives.
Various types of hopper can be customized according to customer requirements to maintain the unobtrusive feeding, so as to achieve no pressure in feeding and discharging. Hopper screw pump has higher efficiency, longer service life, and effectively solves customers' problems. The import and export form can be optional fastener, flange type, internal thread, external thread, loose joint. Pump body material can be divided into: cast iron, stainless steel 304, stainless steel 316, 316L, according to the actual medium requirements.
Product advantage
1, hopper screw pump non-pipe connection, feeding convenient and flexible.
2. Conveying medium with high viscosity.
3, conveying media containing solid particles or fibers.
4, continuous, stable pressure, no cyclical pressure fluctuations.
5, the agitation is required to be small and does not damage the inherent structure of the conveying medium.
6, low noise, easy maintenance, with high pressure conveying capacity.

Product introduction
G-type gearbox reducer screw pump is a new type of pump that works according to the principle of rotary meshing displacement. The main working parts are eccentric screw (rotor) and fixed bushing (stator). Due to the special geometry of the two components, a separate sealed cavity is formed, and the medium flows uniformly from the axial direction, the internal flow rate is low, the noise is low, the volume remains unchanged, and the pressure is stable, so there will be no eddy current and agitation, and the medium will not be destroyed by the inherent structure. Because the stator is made of a variety of elastic materials, the transmission of high-viscosity fluid and the transmission of medium containing hard suspended particles or medium containing fiber has the characteristics that the general pump can not be qualified for. Its flow rate is proportional to the speed.
Product advantage
Continuous low pulsation transmission, not affected by pressure and viscosity fluctuations.
Wide range of applications, can transport flowing or even non-flowing materials.
The medium will not be stirred during the pumping process, and will not be squeezed and cut.
High efficiency, the throughput is proportional to the speed, and the throughput can be adjusted by frequency conversion.
Most liquids can be pumped with small agitation and pulsation.
Easy maintenance, with high pressure conveying capacity.

G type single screw pump
A rotor-type positive displacement pump that relies on screw and bushing to engage with each other to produce volume changes in the suction cavity and the discharge cavity to transport liquid
G type single screw pump belongs to the rotor type positive displacement pump, which relies on the screw and the bushing meshing each other in the suction cavity and the discharge cavity to produce volume changes to transport liquid. It is a kind of internal meshing closed screw pump, the main working parts are composed of a bushing (stator) with a double head spiral cavity and a single head spiral screw (rotor) engaged in the stator cavity.
G type single screw pump belongs to the rotor type positive displacement pump, which relies on the screw and the bushing meshing each other in the suction cavity and the discharge cavity to produce volume changes to transport liquid. It is a kind of internal meshing closed screw pump, the main working parts are composed of a bushing (stator) with a double head spiral cavity and a single head spiral screw (rotor) engaged in the stator cavity. When the input shaft drives the rotor around the center of the stator for planetary rotation through the universal joint, the stator-rotor pair is continuously meshing to form a sealed cavity, and the volume of these sealed cavities is constant and uniform axial movement, the conveying medium is transported from the suction end through the stator-rotor pair to the extrusion end, and the medium in the suction closed cavity flows through the stator without being stirred and destroyed.
The inner surface of the bushing has a double thread, and its arbitrary cross-section is a long circle, both ends are a semi-circle with a radius of R (equal to the radius of the screw section), and the middle is a straight line segment with a length of 4e. Any section of the bushing is the same long circle, but staggered one Angle from each other.
After the screw is loaded into the bushing, a closed chamber is formed between the screw surface and the inner thread surface of the bushing, and any section is also divided into the upper and lower two crescent shaped studios. When the screw rotates, the volume of the first studio near the suction chamber gradually increases, forming a negative pressure, and the liquid is sucked into the studio under the action of the pressure difference. With the continuous rotation of the screw, the volume of the working chamber is increased to the maximum, and the studio is closed and the liquid is pushed axially to the extrusion chamber. At the same time, the upper and lower studios alternately inhale and discharge the liquid, so that the liquid is continuously pushed from the suction chamber to the extrusion chamber along the axial direction.
