Working principle of vacuum negative pressure station system

If you want to use the vacuum negative pressure station system better, you need to understand its working principle. Let me introduce its working principle to you. 1. Vacuum station equipment composition: A single or double vacuum pump is used as the main equipment for vacuum acquisition, a vacuum tank is used as a vacuum storage device, and the electrical control part is connected to form a vacuum negative pressure station. Dual pump operation can enhance the security of the system. For situations where the vacuum source is frequently used but the required air pumping volume is not too large, this vacuum station system saves energy compared to directly using a vacuum pump as the vacuum source, and effectively extends the service life of the vacuum pump and improves the economic benefits of the enterprise.
2. The upper and lower vacuum limits of the vacuum station can be set between to and with the vacuum gauge, and the error value is %.
3. The gas storage tank for the vacuum station is manufactured according to user requirements, generally between . and m. After the vacuum station is started, the vacuum degree in the vacuum tank is always maintained between the set upper and lower limits.
4. Control mode
Single pump automatic and manual control.
, Two pumps are on and one is on standby, or the two pumps are separated and the single pump is automatically cycled at a scheduled time, or the two pumps are automatically controlled for linkage operation at the same time.
5. Each pump of the vacuum negative pressure station is equipped with a set of inflatable electromagnetic check valves to prevent vacuum oil return failure.
