Basic Functioning And Benefits Of A Dry Claw Vacuum Pump
Posted in Uncategorised, on April 22, 2022 By Admin
When it comes to industrial pumps, there are plenty of options to choose from. Two of the most popular ones are rotary vane vacuum pumps and liquid ring pumps. However, for some specialized purposes, a dry claw vacuum pump might be the best choice in terms of performance and maintenance. To understand this type of pump better, the brief operating mechanism of a dry claw vacuum pump will be discussed down below.
How does a dry claw vacuum pump work?
In a basic claw vacuum pump, there are two rotors within a cylinder that are shaped like a claw, hence the name. These two rotors move in opposite directions to one another, thereby creating a vacuum. The air or gas that is meant to be pumped gets sucked into this vacuum and is eventually compressed and discharged effectively. The two rotors and the cylinder don’t come in contact with one another, however, they do come very close.
This extremely tight clearance further helps in maintaining a high pump speed, consequently improving the efficiency of the claw pump. It also prevents the gas from flowing back, creating a dry seal in the process. Overall these pumps can be more efficient than a rotary vane pump by almost 30 percent, if not more.
Here are a few additional benefits of using a dry claw vacuum pump:
- Since they pump gas that might be flammable, they are made to be robust yet compact.
- As the rotors don’t touch one another, the probability of friction and consequent wear and tear is avoided.
- Since the mechanism is completely dry, there is no need for lubrication in the pumping chamber. Although it does increase the temperature of the rotors significantly.
