The start-up and operation of water ring vacuum pump is inseparable from the configuration of power supply. If the power supply is not stable or directly blocked, the vacuum pump will not be able to run, and the work progress will be delayed. Of course, its power configuration is not only power on, but also can prolong its operation time and improve the efficiency of use. Therefore, some methods and errors of power supply configuration are proposed Area users still need to fully understand.
Water ring vacuum pump power supply configuration method:
1. After the water ring vacuum pump is connected with the power supply, the power supply voltage should be stable under any load and working conditions. With switching power supply is a better solution. If the power supply is not regulated, the voltage may be very high when the vacuum pump is not connected. Once the pump is connected, the power supply voltage will drop sharply. Even if the voltage after connecting the pump is equal to the rated working voltage. At this time, the power supply voltage will fluctuate abnormally, leading to the pump’s work will be completely disordered.
2. It is also not advisable to divide and depressurize by resistance, because the working current of water ring vacuum pump will change when the load of gas (water) circuit changes, which will lead to the change of resistance partial pressure. Therefore, the power supply must have voltage stabilizing function. In actual purchase, with and without voltage stabilizing function, the price difference is very small, it is recommended to buy with voltage stabilizing function.
3. The output current that the power supply can provide must be larger than the working current of the pump, so as to ensure the energy demand of the vacuum pump. And choose power supply, must not choose the price is too cheap switching power supply. In order to attract customers to buy this kind of power supply, the parameters usually have false mark and false report.
Misunderstanding of power supply configuration of water ring vacuum pump:
1. This kind of problem is easy to occur if the electric control element (such as manifold block) is used to directly supply power to the pump.
2. A customer used 12v6a switching power supply to power the claw type high-pressure water pump. As a result, the vacuum pump did not move after it was moved. It was thought that the pump was faulty. After replacing it with 12v14a power supply, the problem was solved.
The power configuration of water ring vacuum pump must be taken seriously, and the user should also consider the actual situation of the machine, otherwise it will lead to mismatched power configuration method, which will cause certain failure to the vacuum pump itself. Therefore, in order to ensure the stable operation of the vacuum pump after power on, its various components can play a corresponding role in its power configuration Methods and misunderstandings should be firmly remembered.
