The introduction of vacuum system and system structure composition

The vacuum system is actually a similar name for the vacuum unit, and the vacuum unit is a set of closed-loop vacuum equipment composed of several vacuum pumps. There are many kinds of vacuum application equipment, but no matter what kind of vacuum application equipment has a set of pumping system to remove the gas in the pumped container, so as to obtain the required vacuum conditions in the vacuum container. For example: a vacuum treatment of the container, with pipes and valves to connect it to the vacuum pump, when the vacuum pump to evacuate the container, the container to have a vacuum measuring device, which constitutes a most simple vacuum pumping system.

Any vacuum system composed of more than two vacuum pumps in series, usually the pump pumping low vacuum is called its upper high vacuum pump before the pump (or pre-pump), and the highest level of the vacuum pump is called the main pump of the vacuum system, that is, the most important pump, the limit vacuum degree in the pumped container and the working vacuum degree are determined by the main pump. The pipe between the outlet of the pumped container and the entrance of the main pump is called the high vacuum pipe, and the valve at the entrance of the main pump is called the main valve.

Usually the front pump also doubles as a pre-vacuum pump. The pipeline between the pumped container and the 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 pipe is called the front pipe valve, and the soft connection pipe is set to isolate the vibration of the front pump.

In summary, a better vacuum system consists of the following components:

1, Pumping equipment: such as various vacuum pumps

2. Vacuum valve

3. Connect the pipes

4, Vacuum measuring device: such as vacuum pressure gauge, various regulations

5, Other components: such as collector, dust collector, vacuum relay gauge head, gas storage tank, etc.

The vacuum system can be summarized in one sentence: an extraction system used to obtain a specific required vacuum degree.

The basic content of vacuum system design: according to the requirements of the vacuum degree of the pumped container, choose the appropriate vacuum system design scheme, select and match the pump calculation; Determine the pipe, valve, trap, vacuum measuring components, etc., reasonable configuration, and finally draw the vacuum system assembly drawing and parts drawing.
