ZF series vacuum pumping station

Overview:

　　ZF series vacuum pumping station (also known as vacuum generating device, vacuum negative pressure station, etc.) is a complete system of vacuum storage equipment with one or two water ring vacuum pumps as vacuum acquisition equipment. For applications where the vacuum source is frequently used and the required pumping volume is not too large, the system saves energy compared to the direct use of the vacuum pump and effectively increases the service life of the vacuum pump.

　　The equipment can provide vacuum source for medical gas central station for various large and medium-sized hospitals in China, and is widely used in vacuum stations in chemical and pharmaceutical industries, canning systems in light industry, and vacuum forming of rubber and plastic engineering parts in automotive industry. The impregnation of the flame retardant conveyor belt for coal mines and the vacuum source of the foundry industry (V method, VRH, V-EPC).

Working principle:

　　1, two vacuum pumps

　　First set the upper and lower limits of the vacuum system (for example, the upper limit is set to -0.08MPa, the lower limit is set to -0.06MPa). After starting the system, one of the vacuum pumps starts working until the vacuum is high. At the upper limit of -0.08MPa, the vacuum pump automatically stops running, and the vacuum in the vacuum tank is automatically cut off by the vacuum check valve. If the vacuum in the vacuum tank falls below the lower limit of -0.06MPa due to the working demand, the other The vacuum pump is automatically started until the vacuum degree in the vacuum tank is drawn to the upper limit of -0.08 MPa. This cycle repeats the automatic operation so that the vacuum inside the vacuum tank is always maintained between the upper and lower limits. If the working volume is large, the vacuum in the vacuum tank is lower than the lower limit for more than a certain period of time, and when a single vacuum pump cannot pump the vacuum inside the tank to the lower limit, the other vacuum pump will automatically start until the upper limit is exceeded.

　　The two vacuum pumps can also be switched to manual start and stop.

　　2, a vacuum pump

　　First set the upper and lower limits of the vacuum system (for example, the upper limit is set to -0.08MPa, the lower limit is set to -0.06MPa). After the system is started, the vacuum pump is automatically stopped when the upper limit is reached, and the system vacuum is lower than the lower limit automatically. Boot up. The vacuum pump can also be manually started and stopped.

　　Animal characteristics:

　　After the device is started for the first time, all running processes can be fully automated. During the working process, the vacuum in the vacuum system always fluctuates within its allowable range, and the fluctuation range can be adjusted according to user requirements.

　　The device automatically controls the system in the absence of operation, and automatically closes the vacuum system during a power outage.

　　The unit is equipped with a soda separator to save water and reduce environmental pollution.

　　The vacuum tank of the device can be designed horizontally and vertically according to the site, and the installation is more flexible.
