3GF Three Screw Pump (Bracket Installation)

3GF three screw pump (bracket installation), working principle of 3GF three screw pump (flange type)

The active screw is driven to rotate by the driving motor or motor. Due to the gap between the active screw and the driven screw, an oil film is formed in the gap. The oil film can protect the rotating screw and screw, as well as the wear of the screw spiral groove and the inner hole of the liner when the screw and liner mesh with each other, and seal them, gradually forming a negative pressure zone in the pump chamber. At this time, under the action of atmospheric pressure, the liquid is pressed into the low-pressure zone of the pump chamber for pressure replenishment and balance. The driving motor continues to rotate, continuously forming a vacuum zone in the pump chamber. At the same time, the screw between the low-pressure zone and high-pressure zone of the pump chamber gradually forms higher pressure, and the liquid begins to be continuously transported under the action of atmospheric pressure.

Usage of 3GF Three Screw Pump (Bracket Installation)
The 3GF three screw pump (bracket mounted) is used to transport media with a temperature ≤ 150 ℃, viscosity 3-760cSt, no solid particles, non corrosive, and lubricating properties.
Applicable pressure range: 0.6-2.5Mpa;
Applicable flow range: 0.6-123m3/h.
Mainly used in fuel transportation, hydraulic engineering, ship engineering, petrochemical and other industries.

The main features of the 3GF three screw pump are:
1. Reasonable structure and superior performance: Changing traditional high-pressure balancing technology, adopting axial force low-pressure balancing devices for the main and auxiliary rods, uniform force balance, no deformation of the screw, reliable and stable operation, no pulsation, and low noise;
2. Unique design, reliable sealing: The pump adopts a mechanical seal form, and the sealing chamber pressure is connected to the suction pressure. At the same time, the structural design provides sufficient cooling circulation for the seal, improving the sealing effect and ensuring no leakage;
3. Optimization and improvement, beautiful appearance: Change the traditional position of the inlet and outlet, so that the inlet and outlet are distributed on both sides of the pump and form a straight line, beautiful appearance. At the same time, innovate in design, and achieve interchangeability of inlet and outlet without changing the pipeline at the user's site;
4. Pump core components for easy maintenance and replacement of accessories: The pump structure is simple and compact, and the pump core assembly adopts a modular structure that can be removed as a whole for easy maintenance and repair;

Application scope of 3GF type three screw pump (flange type)
1. The medium is conveyed continuously in a straight line, without stirring or pulsation.
2. Low vibration and noise.
3. High pressure and efficiency.
4. Simple structure and easy disassembly and assembly.
5. Small size and light weight.
6. Slight wear and tear, long lifespan.

Structural form of 3GF three screw pump
3GF three screw pumps generally use mechanical seals. The pump is driven by an electric motor through a claw type coupling. Rotate clockwise from the extended end of the main shaft towards the pump.
