ZF series vacuum negative pressure station (vacuum generating device)Detailed product description：

The ZF series vacuum negative pressure station (vacuum generating device) is a complete system that uses one or two water ring vacuum pumps as vacuum acquisition equipment and a vacuum tank as vacuum storage equipment. For situations where the vacuum source is frequently used and the required pumping volume is not too large, this system greatly saves energy compared to directly using a vacuum pump and effectively improves the service life of the vacuum pump.

This equipment can provide vacuum sources for medical gas center stations in various large and medium-sized hospitals in China, and is widely used in vacuum stations in the chemical and pharmaceutical industries, canning systems in the light industry, negative pressure forming of rubber and plastic engineering parts in the automotive industry, impregnation of flame-retardant conveyor belts in coal mines, and vacuum sources in the casting industry (V-method, VRH, V-EPC). Our company also undertakes the installation of equipment for centralized oxygen supply, negative pressure, and suction engineering in various hospitals.

Working principle of the ZF series vacuum negative pressure station (vacuum generator):
Firstly, set the upper and lower limits of the vacuum system (for example, set the upper limit to -0.08MPa and the lower limit to -0.06MPa). After starting the system, one of the vacuum pumps starts working until the vacuum degree in the vacuum tank is higher than the upper limit value of -0.08MPa. At this time, the vacuum pump automatically stops running, and the vacuum in the vacuum tank is automatically cut off by the automatic check valve. If the vacuum degree in the vacuum tank drops below the lower limit value of -0.06MPa due to work requirements, the other vacuum pump automatically starts until the vacuum degree in the vacuum tank reaches the upper limit value of -0.08MPa. This cycle is repeated automatically to keep the vacuum degree in the vacuum tank between the upper and lower limits.

Performance characteristics of vacuum negative pressure station:
After the first start-up, the entire operation process of the device can achieve fully automatic control. During its operation, the vacuum degree in various parts of the vacuum system always fluctuates up and down within its allowable range, and the fluctuation range can be adjusted according to user requirements. If the vacuum level falls below the set value, the alarm will sound a warning.
This device automatically controls the system without human operation and can automatically close the vacuum system during power outages.
The device is equipped with a steam water separator, which can save water sources and reduce environmental pollution.
