What is a vacuum system
What are the components of a complete vacuum system?
There are many kinds of vacuum system equipment, but any vacuum application equipment has a set of exhaust system to remove the gas in the vacuum container, so as to obtain the necessary vacuum conditions in the vacuum container. For example, containers for vacuum treatment are connected to vacuum pumps through pipes and valves. When the vacuum pump empties the container, there is a vacuum measuring device on the container. This constitutes the simplest vacuum pump system.
The simplest vacuum system can only obtain vacuum in the low vacuum range of the pump container. When a vacuum with a high vacuum range is needed, the vacuum system of the high vacuum pump is usually connected in series. When high vacuum pumps are connected in series, valves are usually added at the inlet and outlet of the valve. High vacuum pump to maintain vacuum. If the series high vacuum pump is an oil diffusion pump, in order to prevent a large amount of oil vapor flow back to the pump container, usually add a trap at the entrance of the oil diffusion pump, water-cooled baffle. According to the requirements, dust collector, vacuum relay head, vacuum soft connection pipeline, vacuum pump inlet exhaust valve and so on can be added to the pipeline to form a more perfect high vacuum system.
A vacuum system consisting of two or more series vacuum pumps is usually called a low vacuum pump, which is used as the front pump (or front pump) of a high vacuum pump, and the highest vacuum pump is called the main pump. Vacuum system, that is to say, it is the most important pump, the limit vacuum and working vacuum in the pump container are the main ones. The pump is fixed. The pipeline between the outlet of the pump container and the inlet of the main pump is called the high vacuum pipeline, and the valve at the inlet of the main pump is called the main valve.
Usually, the front pump is also used as a vacuum pump. The pipeline between the pump container and the pre-pump is called the pre-vacuum pipeline, and the valve on the pipeline is called the pre-vacuum pipeline valve. The pipe between the main pump outlet and the front pump inlet is called the front pipe. The valve on the pipeline is called the front pipeline valve, and the soft connection pipeline is set to isolate the vibration of the front pump.
In summary, a more complete vacuum system consists of the following components:
1. Pumping equipment: for example, various vacuum pumps;
2. vacuum valve;
3. Connecting pipes;
4. Vacuum measuring devices, such as vacuum gauges and various regulators.
5. Other components, such as traps, dust collectors, vacuum relays, tanks, etc.
What is a vacuum system? To sum up, it is a pumping system used to obtain a certain degree of vacuum.
The basic content of the vacuum system design is: according to the vacuum requirements of the pumping vessel, choose the appropriate vacuum system design scheme, select and calculate the pump; determine the conduit, valve, trap, vacuum measuring elements, and make a reasonable configuration, and finally draw the vacuum system component diagram and components.
