Claw Vacuum Pump

They turn in opposite directions in a compressor housing without contact observing very tight clearances.

Claw vacuum pump.

The vsd provides the right amount of vacuum at all times. Variable speed drive technology matches motor speed to vacuum demand resulting in maximum efficiency of the vacuum system. Claw vacuum pumps are ideally suited to use with frequency controlled drives. There are also variants for special applications such as dust and gas explosion protection high steam contents gas tightness and increased oxygen contents.

Although commonly used in series with a roots style booster pump fig. A claw vacuum pump is a very low maintenance tool and has integrated cooling air without the need for additional cooling mechanisms. Tight clearances between the claw rotors and the housing optimise the internal seal and guarantee a consistently high pumping speed. Claw vacuum pump characteristic and application.

Medical claw vacuum systems standard with vsd. Mink claw vacuum pumps and compressors are the result of continuous development in claw technology. Claw vacuum pumps are available in a wide range of sizes. In medical facilities the vacuum system must react to continuous demand fluctuations.

In contrast to rotary lobes compression happens internally by volume contraction. A claw pump consists of two rotors. No more no less. This is possible because of the principle of internal compression in the rotary claw design.

Internal compression allows for low pressure and low power motors while the performance curve. Two and three stage claw pump designs are typical which utilize multiple claw rotors in series. The gas is pre compressed within the compressing chamber and is then discharged. The flow capacities range from 43 to 671 cm and the maximum ultimate vacuum capacity is up to 28 44 hgv 32 psig.

In the process of describing the operation principle we have learned that the claw vacuum pump can compress gas in operation and the rotor has the function of self opening and closing valve in the process of rotation which can achieve high compression ratio and volume efficiency and ensure. A synchronization gearbox ensures exact synchronization of the claw rotors. Kcp vacuum pumps are driven by a directly flange mounted asynchronous motor with an efficiency class ie2 ie3. The c series dry claw vacuum pumps of elmo rietschle generate contact free vacuum or compressed air efficiently and economically.

2 a claw pump can be used alone when high vacuum is not required and or slower pumpdown rates are acceptable.
