ZF series.pdf

Summary:

ZF series vacuum pump station(also known as a vacuum generating device, vacuum station) is in one or two water ring ZF package unit is a kind of whole sets for storing vacuum, which is composed of one or two water ring vacuum pumps as the device for obtaining vacuum and the vacuum container device for storing vacuum. When the vacuum resource is required constantly and the suction capacity is not required a lot, to use the ZF package unit can save more energy than to use the vacuum pump directly and this can improve the vacuum pump lifetime efficiently.

The ZF series package units are used as the vacuum resource in the large or middle domestic hospitals. They are used extensively as the vacuum station in the chemical and pharmacy, or the canning system in the light industry, or the negative molding of the rubber object in automobile area, or the vacuum sorking of the flammable resistant transmission in mine coal, or the vacuum resource for the molding area etc.

Work principle:

1,Two vacuum pumps
Set the highest and the lowest vacuum limit of the vacuum system（For example: the highest vacuum is set at-0.08MPa and the lowest vacuum is set at -0.06MPa). When the ZF unit starts, one pump begins to work. Till the vacuum in the container reaches -0.08MPa，the vacuum pump stops automatically and the vacuum status of the container is stored temporary by the non-return valve stopping automatically. If the vacuum in the container is lower than -0.06MPa，another pump works automatically till the vacuum in the container increases to -0.08MPa. By repeating this process, the vacuum in the container always maintains between the highest and the lowest value. If the suction capacity is required stronger, or the vacuum in the container becomes lower than the lowest limited for a period, so the single vacuum pump is not able to reach the lowest limit and the other pump will start automatically till the vacuum in the container becoming even higher than the highest limit. These two pumps can also be switched to manual control for on and off.

2,One vacuum pump
At first, to set the highest and the lowest vacuum limit of the vacuum system (for example: the highest vacuum is set at -0.08MPa and the lowest vacuum is set at -0.06MPa. When the ZF unit starts , the vacuum pump works till the vacuum in the container reaching the highest vacuum. And when the vacuum in the container is lower than the lowest vacuum, the vacuum pump works again automatically. The vacuum pump can also be switched to manual control for on and off.

Performance characteristics:

·  The device after the first start, all run process can realize the automatic control. In the process of working, everywhere in the vacuum system of the vacuum degree always within the allowable range fluctuations, and the fluctuation of range can be adjusted according to the requirements of users. If the vacuum is lower than the setting value, the alarm will be issued a warning.

·  The device can automatically control the system when the power is cut off, and the vacuum system can be automatically closed during power failure.

·  The device is equipped with a gas water separator, which can save water and reduce environmental pollution.

·  The vacuum tank of the device can be designed for horizontal and vertical structure according to the site, and the installation is more flexible.

 ·  Note:

·  The above model pump vacuum is the recommended products, but also according to the actual situation to choose the appropriate pumping speed of the pump vacuum model.

·  Optional pump vacuum, recommended priority selection of efficient and energy-efficient series 2BV water ring type pump vacuum, the technical parameters, please refer to:

·  2BV series water ring vacuum pump　　　　SK series water ring vacuum pump

Above models for our standard series products, but also according to the user for custom-made special-shaped vacuum tank, equipped with a vacuum pump, customized interface flange size.

Vacuum tank can be designed as a horizontal or vertical structure according to the user requirements, please specify when ordering.
