Explosion proof screw vacuum pump

Screw Pumps Description

The screws of the pump are interlocked to pressurize the fluid and move it inside the system. These screws are meshed with each other and reciprocate in the cavity of the cylinder.

In this pump, the fluids enter the pump through the inlet valve and flow linearly toward the outlet side of the pump along with the interlocking screws. The small gap between the screw and the cavity increases the fluid pressure when fluid flows through the pump.

The rotary screw pumps are most commonly used in various industries such as power generation, shipping, chemical processing, terminals, refineries, pipelines, and oil and gas production. In the power generation zone, these pumps are utilized for jacking oil, fuel supply, high-pressure fuel injection, gear and bearing lubrication, and water power for applications in the control of hydroelectric plants.

Screw Pumps construction

A screw pump has an easy and reliable construction. It is very easy to design. There are three screw spindles, two of which are driven screws and the other screw is a driver. There is enough clearance between these screws, which is responsible for pumping the water or other fluid. The electric motor supplies the fluid to the screws.

This type of pump has a housing with suction and discharge sides. The suction valve is located at the pump base, while the discharge valve is located at the top of the pump. In addition, it has a check valve at the discharge side that prevents the backward flow of the fluid. All of this can observe in the pump design.

Advantages of Screw Pump

• Screw pumps have many advantages over centrifugal pumps. First, the pumped liquid moves axially without turbulence. This eliminates bubbles created by viscous liquids.
• These pumps have easy maintenance.
• Screw Pumps can use for all fluids
• It can run dry
• It has a compact construction
• These pumps deliver a constant and non-pulsating flow of fluid
• These have a quiet operation
• This pump can produce extended volumetric efficiency
• It needs very low maintenance
• It has high reliability
• Self-priming ability
• High robustness
• It has high tolerance against dust particles and water vapors
• It pumps the fluid at a very high speed
• A screw pump doesn’t pump the contamination of the fluid.
• It has a frictionless rotation
• It has very high efficiency
• Rotary screw pumps have low pulsations
• With screw pumps, you can also pump high viscous fluids without losing the flow
