ZF series vacuum pump station (also known as vacuum generating device, vacuum station, negative pressure station, vacuum negative pressure station, etc.) uses one or two water ring vacuum pumps (or other forms of vacuum pumps) as vacuum obtaining equipment, and vacuum tanks as vacuum Complete system of storage equipment. In the case of frequent use of a vacuum source and a small amount of suction is required, the system saves energy greatly and directly improves the service life of the vacuum pump than using a vacuum pump directly.
This equipment can provide vacuum sources for medical gas central stations for 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, and negative pressure molding of rubber and plastic engineering parts in the automotive industry. Flame retardant for coal mine
Vacuum source for impregnation and casting industries (V-method, V-EPC), etc.
1. After the device is started for the first time, the entire operation process can be fully controlled. In the course of its work, the vacuum degree of each place in the vacuum system always fluctuates up and down within its allowable range, and its fluctuation range can be adjusted according to user requirements.
Second, the device can be widely used in various types of systems that require vacuum. At the same time, it can also automatically control the system without any operation; it can automatically close the vacuum system when the power is off. Using this equipment can make your vacuum system more advanced, safe and energy efficient.
3. The device is equipped with a gas-water separator (when the equipment is equipped with a water ring vacuum pump), which can save water resources and reduce environmental pollution.

First set the upper and lower limits of the vacuum system (for example, the upper limit is set to -0.08MPa and the lower limit is set to -0.06MPa). After the system starts, one of the vacuum pumps starts to work until the vacuum in the vacuum tank The vacuum degree is higher than the set upper limit value -0.08MPa. At this time, the vacuum pump stops automatically, and the vacuum in the vacuum tank is automatically cut off by the automatic check valve. If the vacuum degree in the vacuum tank falls below the lower limit value -0.06 due to work requirements At MPa, another vacuum pump is automatically started until the vacuum in the vacuum tank reaches the upper limit of -0.08 MPa. This cycle is repeated and automatically operated to keep the vacuum in the vacuum tank between the upper and lower limits.
Two-pump vacuum pumps can also be made into one-use and one-standby type.

Common malfunctions

Cause and repair

1

System vacuum is low

Check if the vacuum pipeline is leaking, check whether the valve is normal, and the water ring pump is installed incorrectly (according to the water ring pump instruction manual)

2

Water ring pump is not working properly

Close the pipeline and waterway, and repair the vacuum pump. And check whether the water supply is normal, whether water is added and the amount of water.

3

Automatic control failure or control failure

Check the circuit according to the schematic diagram of the electrical appliance, whether the electrical contact vacuum meter wiring is loose or disconnected, whether the power supply is normal, and whether the AC contactor of the control cabinet is damaged.

4

Motor Weng ring, do n’t turn

The three-phase motor is out of phase. Check whether the three-phase power supply in the control cabinet is normal and whether the three-phase wire of the motor is falling off.

5

Noisy vacuum pump

系列真空泵工作在极限时会发出汽蚀声, 如噪音较大须打开汽蚀保护口。 The 2BV series vacuum pump will emit cavitation sound when working at the limit. If the noise is loud, the cavitation protection port must be opened.
