Hey there! As a supplier of Mechanical Booster Pumps, I often get asked about how these pumps work in conjunction with a pre - pump. So, let's dive right into it and break down the process.
First off, let's understand what a Mechanical Booster Pump is. A mechanical booster pump is a positive - displacement pump. It's designed to increase the pumping speed and reduce the ultimate pressure in a vacuum system. But it can't work on its own. That's where the pre - pump comes in.
The pre - pump is like the foundation of the whole vacuum system. It's responsible for creating an initial vacuum in the system. Without a pre - pump, the mechanical booster pump wouldn't be able to function properly. The pre - pump brings the pressure in the system down to a certain level where the mechanical booster pump can take over and further reduce the pressure.
There are different types of pre - pumps that can be used with a mechanical booster pump. One common type is the Auxiliary Vacuum Pump. The auxiliary vacuum pump is used to provide the initial vacuum for the mechanical booster pump. It starts the process by removing a large amount of gas from the system. Once the pressure is reduced to a suitable level, the mechanical booster pump can start working.
Another type of pre - pump is the Seal Oil Vacuum Pump. This type of pump is often used in systems where there's a need to seal the pump and prevent leakage. It helps to create a stable vacuum environment for the mechanical booster pump to operate.
Now, let's talk about how they work together. When the system is first started, the pre - pump begins to remove gas from the chamber. It keeps pumping until the pressure in the chamber reaches a point where the mechanical booster pump can start. This is usually around a pressure of 1 to 10 millibars.
Once the pre - pump has achieved this pressure, the mechanical booster pump kicks in. The mechanical booster pump has two or more rotors that rotate in opposite directions. These rotors trap the gas and move it from the inlet to the outlet of the pump. As the rotors rotate, they create a series of chambers that expand and contract. This movement of the chambers helps to increase the pumping speed and reduce the pressure further.
The combination of the pre - pump and the mechanical booster pump allows for a much more efficient vacuum system. The pre - pump takes care of the initial heavy lifting of removing a large volume of gas, while the mechanical booster pump focuses on achieving a higher level of vacuum.
One of the advantages of using a mechanical booster pump with a pre - pump is the increased pumping speed. The mechanical booster pump can pump a large volume of gas in a short period of time, which is great for applications that require a quick evacuation of the chamber.
Another advantage is the ability to achieve a lower ultimate pressure. By working together, the pre - pump and the mechanical booster pump can reach pressures that are much lower than what a single pump could achieve on its own.
However, there are also some things to keep in mind when using a mechanical booster pump with a pre - pump. For example, the pre - pump needs to be properly sized for the mechanical booster pump. If the pre - pump is too small, it won't be able to create the necessary initial vacuum, and the mechanical booster pump won't work effectively.
Also, the operating conditions of the pre - pump and the mechanical booster pump need to be carefully monitored. The temperature, pressure, and flow rate of the gas need to be within the acceptable range for both pumps.
In terms of maintenance, both the pre - pump and the mechanical booster pump require regular upkeep. The pre - pump may need to have its oil changed regularly, and the mechanical booster pump may need to have its rotors inspected and cleaned.
