Product Overview:

1、 Product Overview of G-type Screw Pump:

G-type screw pump is a new type of pump that works according to the principle of rotary meshing displacement. The main working components of G-type screw pump are eccentric screw (rotor) and fixed liner (stator). The G-type screw pump uses non-toxic and odorless edible rubber, with a working temperature of up to 120 ℃. Due to the special geometric opening of these two components, they form separate sealed chambers. The medium flows uniformly in the axial direction. The internal flow rate is reduced while the volume remains unchanged. The pressure is stable, so there will be no product turbulence or agitation.

2、 The purpose of G-type screw pump:

Wide range of applications: environmental protection, shipbuilding industry, petroleum industry, pharmaceuticals, daily chemical products, canned food industry, brewing industry, construction industry, printing, papermaking industry, etc. It is widely used in industrial sectors such as food metallurgy, papermaking, printing and dyeing, chemical industry, fertilizer and pharmaceuticals.

3、 Characteristics of G-type screw pump:

This type of pump has few parts, compact structure, small volume, and easy maintenance. The rotor and stator are the vulnerable parts of this pump, and the structure is simple and easy to assemble and disassemble.

Capable of transporting media with high solid content; Uniform flow and stable pressure, especially at low speeds; The flow rate is directly proportional to the pump speed, thus having good variable adjustability; A pump with multiple uses can transport media of different viscosities; The installation position of the pump can be tilted arbitrarily; Suitable for transporting sensitive items and items that are susceptible to damage such as centrifugal force;

4、 The working principle of G-type screw pump:

G-type screw pump is an internal meshing rotary displacement pump. When the rotor of the single helix rotates around the stator axis in the stator hole of the double helix, the closed chamber formed between the rotor and stator continuously, uniformly, and with a constant volume transports the medium from the suction end to the discharge end. Due to these characteristics, single screw pumps are particularly suitable for the following working conditions:

Transportation of high viscosity media. The viscosity of the medium varies depending on the size of the pump, ranging from 20000 MPa. s to 200000 MPa. s.

Media containing solid particles or fibers. The particle size can reach up to 16mm (not exceeding the rotor eccentricity), the fiber length can reach 100mm (equivalent to 0.4 times the rotor pitch), and the solid content can generally reach 40%. When the solid contained in the medium is fine powder particles, it can reach up to 60% or higher.

Require continuous delivery, stable pressure, and no periodic pressure fluctuations of reciprocating pumps.

Require minimal agitation during transportation, without damaging the inherent structure of the conveyed medium.

Low noise.

6、 Precautions for using G-type screw pump

Before starting the G-type screw pump, the direction of operation must be determined first and must not be reversed.

2. It is strictly prohibited to operate the G-type screw pump without a medium to avoid damaging the stator.

3. For newly installed or shut down pumps that cannot be started immediately, an appropriate amount of engine oil should be injected into the pump body first, and then the pipe clamp should be turned a few times before starting.

After conveying high viscosity or media containing particles and corrosiveness, rinse with water or solvent to prevent blockage and avoid difficulty in starting next time.

5. In winter, liquid accumulation should be eliminated to prevent freezing and cracking.

During the use of G-type screw pumps, lubricating oil should be regularly added to the bearing box. If seepage is found at the shaft end, the oil seal should be promptly treated or replaced.

If any abnormal situation occurs during the operation of the G-type screw pump, it should be stopped immediately to check the cause and eliminate the fault.
