Claw vacuum pump compression
Claw vacuum pump compression
September 28, 2016

A classic rotor pump has several arms caged in a single enclosure through which the fluid being pumped passes through for pressurization. A less talked about type of the rotor pumps is the claw vacuum pump series which comes with two claw-shaped rotors rotating in opposite directions. For more efficiency, the claws are designed not to touch the walls of the casing, but rather create an effectively small margin between the claw ends and the housing. This ensures that the fluid gets adequate pressure as it is propelled towards the exterior port.

 

As the claws rotate, they do not come into contact but create an extremely small clearance. The small clearance creates a small opening through which the fluid oozes at high pressure before being propelled outwards by the rotating claws. With the positioning of the claws being close to the inlet port, air is sucked into the compression chamber where the process is repeated as the claws continue rotating. This reduces the volume of the air within the claws leading to an increase in the pressure of the air within. With the claw vacuum pump being the oil free type, any heat generated during the air compression is effectively dissipated through the metallic casing of the compression chamber.

 

Since a claw vacuum pump operates with a combined sanction and compression principle, they can be suitably used as vacuum pumps or blowers. When used as a blower, the pump excerpts low pressure on a large volume of the fluid in consideration. On the other hand, using it as a vacuum pump allows the claws exert pressure of under 30Psi, hence considered low pressure pumps.

I always thought claw vacuum pumps relied on oil?
