What Are Vacuum Pumps And Their Types?
We all need different types of tools or equipment in our daily lives for sheer convenience and access. These tools are generally designed and provided to consumers for specific purposes. Such is the case with vacuum pumps. It is a kind of equipment used to create a vacuum in a closed container.
There are multiple types of vacuum pumps available. You can check out LeDab vacuum pumps if you need to get started with vacuum pumps. Each type of pump is available with a different set of features. Different kinds of vacuum pumps are separated based on rotary vane, positive displacement, liquid ring, molecular transfer, etc.
What is a vacuum pump?
A vacuum pump is primarily used for reducing liquid pressure in a closed container. The operation is achieved by using a vacuum system frequently to eliminate surplus air and other elements in a container. These pumps are classified into different types and are used in multiple processes for various needs.
A vacuum pump’s efficiency depends on several parameters, such as throughput and pumping speed. The dimensions for each parameter are different. Before getting a vacuum pump, you should also check or calculate its suction capacity and capability to produce in Hg.
Types of vacuum pumps:
- Regenerative pump
Regenerative pumps are constructed to provide high power consumption ranging between 1 kW to 100 kW. The high power consumption results from reversing atmospheric force within a closed container. Such power consumption numbers can be decreased by using small pumps.
- Positive displacement pumps
A positive displacement pump mainly operates on a mechanism that continuously expands or increases the cavity to allow the gases to flow from an outer chamber. The cavities are opened, and gases are discharged into the atmosphere. Such pumps help create low vacuums.
- Momentum transfer pump
Momentum transfer pumps are also known as molecular pumps. Such pumps work with high-speed fluids for transferring gas particles out of the chamber before opening. One can use these pumps to achieve high vacuums and frequently operate in conjunction with different displacement pumps.
- Entrapment pump
An entrapment pump or cryopump uses cold temperature to compress various gases in a complex state. A chemical pump responds with gases to produce a hard residue in an entrapment pump. An entrapment pump can also use an electrical field to push an ion to ionize the gases into a rigid state.
It would help if you started with a vacuum pump by first finalizing your requirements since each pump has a different purpose for serving your needs.
