Different effects of various vacuum pumps
Jun 06, 2019| In addition to the vacuum pump's function, the vacuum pump can be vacuumed. Different vacuum pumps have different functions. Therefore, it is very important to clearly understand the tasks that the pump undertakes in the vacuum system when selecting. The effects of the pump in various different types of work are summarized as follows.
1. Keep the pump Keeping the pump means that when the vacuum system is very low, it is not useful to use the primary foreline pump. For this purpose, an auxiliary pump with a lower pumping speed is additionally provided in the vacuum system to maintain the normal operation of the main pump or to maintain the low pressure vacuum pump required for the pumped container.
2. Rough vacuum pump or low vacuum pump The rough and low vacuum pump refers to a vacuum pump that operates from the beginning of the atmosphere and drops the pressure of the pumped container after working in a low vacuum or rough vacuum pressure.
3. High vacuum pump refers to a vacuum pump that operates on a high vacuum scale.
4. Ultra-high vacuum pump refers to a vacuum pump operating on an ultra-high vacuum scale.
5. Booster pump The booster pump usually refers to a vacuum pump that operates between a low vacuum pump and a high vacuum pump to improve the pumping capacity of the pumping system at the center pressure scale or to reduce the pumping rate of the foreline pump.
6. Main pump in the system The so-called main pump is a vacuum pump that vacuums the vacuum system directly to obtain the vacuum required for satisfactory technical requirements.
7. Rough pump The rough pump refers to the vacuum pump that can reduce the pressure of the vacuum system from the beginning of the atmospheric pressure to the other pumping system.
8. Foreline Pump The foreline pump is a vacuum pump that is used to maintain the pressure of the front stage of another pump below its highest acceptable pre-stage pressure.
