ZF Series Vacuum Negative Pressure Station (Vacuum Generator) is a complete system with one or two water ring vacuum pumps as vacuum acquisition equipment and vacuum tanks as vacuum storage equipment. For the occasion of frequent use of vacuum source and small amount of pumping required, the system saves much energy than direct use of vacuum pump, and effectively improves the service life of vacuum pump.
This equipment can provide vacuum source for medical gas center station for all kinds of large and medium-sized hospitals in China. It is widely used in vacuum station of chemical and pharmaceutical industries, tank filling system of light industry, negative pressure forming of rubber and plastic engineering parts in automobile industry, impregnation of flame retardant conveyor belt in coal mine and vacuum source of foundry industry (V method, VRH, V-EPC).
Water Ring Vacuum Negative Pressure Station Working Principle:
Firstly, the upper and lower limits of the vacuum system are set (for example, the upper limit is set to -0.08MPa and the lower limit is set to -0.06MPa). After starting the system, one of the vacuum pumps starts to work until the vacuum in the vacuum tank is higher than the upper limit - 0.08MPa. At this time, the vacuum pump stops running automatically and the vacuum in the vacuum tank is automatically cut off by the automatic backstop valve, such as the vacuum in the vacuum tank is reduced to a low level due to the working demand. When the lower limit value is - 0.06MPa, another vacuum pump starts automatically until the vacuum degree in the vacuum tank reaches the upper limit value - 0.08MPa, so that the vacuum degree in the vacuum tank keeps between the upper limit and the lower limit.
water ring vacuum negative pressure station Performance characteristics:
After the first start-up of the device, the whole operation process can be fully automatic controlled. During the working process, the vacuum degree in every part of the vacuum system fluctuates up and down in its allowable range, and its fluctuation range can be adjusted according to the user's requirements. If the vacuum is below the set value, the alarm will give a warning.
The device can automatically control the system without human operation and automatically close the vacuum system when power failure occurs.
The device is equipped with a steam-water separator, which can save water and reduce environmental pollution.
