Vacuum negative pressure station ZF series |
| Description: |
Vacuum negative pressure station ZF series Summary: ZF series vacuum pump station(ie vacuum-producing device or vacuum negative pressure station ) 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, using the ZF package unit can save more energy than using the vacuum pump directly and it can improve the vacuum pump lifetime efficiently. The ZF series package units are used as the vacuum resource in large and middle demostic 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 resource of the flammable resistant transmittion 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 constainer reaches -0.08MPa,the vacuum pump stops automatically and the vacuum status of the container is stored temporary by the non-return valve stoping 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 becomeing even higher than the highest limit. These two pumps can also be switched to manul control for on and off. 2.One vacuum pump: 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  |
