1. Product overview:

Three screw pumps include 3G 3GR three screw pump general type, 3GC marine three screw pump type and 3GS three screw pump 3GCL three screw pump 3GCLS three screw pump and other special types. The three-screw pump is a rotor-type positive displacement pump. Due to the mutual engagement of the spiral grooves on the driving screw and the driven screw and their cooperation with the inner surface of the three holes of the bushing, several stages of dynamic sealing chambers can be formed between the inlet and outlet of the pump. The dynamic sealing chamber will continuously move the liquid axially from the pump inlet to the pump outlet, and increase the pressure of the pumped liquid step by step, thereby forming a continuous, stable and axially moving pressure liquid.

 

2. Product use function:

3 The liquids delivered by GR series three-screw pumps are all kinds of lubricating liquids that do not contain solid particles, non-corrosive oils and similar oils. It can be transported by heating to reduce viscosity. The flow range is 0.2~590m3/h, the maximum working pressure is 100bar, and the maximum temperature is 150℃.

 

3. the scope of application :

1. Hydraulic lubrication equipment

2. Military aerospace

3. Water conservancy and hydropower

4. Compression refrigeration machinery

5. Blower paper making

6. Metal smelting steel

7. Manufacturing of mechanical machine tools

8. Ship port terminal

9. Refining spends money on biochemical

7. Advantages:

1. Modular design scheme → strong general interchangeability and low maintenance cost

2. Light radial wear - resistant sliding bearing → long service life

3. High efficiency → low operating cost

4. The axial force of the screw rotor is balanced → the bearing does not bear the axial force

5. Lower axial flow velocity → excellent starting ability

6. Only one shaft seal → easy maintenance and low cost

7. Resistance to cavitation and gas explosion → low noise and vibration

8. Wide applicability of magnetic drive version with no seal and no leakage design

9. Availability of semi-submersible suspended and long-arm designs → customized diving depths to solve the working conditions where the self-priming capacity of the pump exceeds the atmospheric pressure

10. The design of jacket insulation → solves the problem of high temperature conveying medium

11. A variety of oil inlet and outlet arrangements → meet various on-site installation conditions

12. The most diverse installation methods are available

13. Integrated design version of pump lining → higher cost-effective experience
