Before the equipment and trial operation of water ring vacuum pump, it is necessary to study the planning requirements of vacuum pump, especially some precautions in the imitation list. Do not rely on your own experience for equipment and trial work. For example, you should pay attention to the following points before driving:

(L) select the appropriate height of equipment to prevent the occurrence of indignation and erosion;

(2) Before driving, all the sundries on the vacuum pump should be removed;

(3) Before connecting the coupling, carefully check whether the rotation direction of the motor is in common with the planned direction of the vacuum pump.

Attention should be paid to the following points in the same work process:

(1) Strengthen patrol inspection and monitor whether there is obvious abnormal noise such as collision and conflict when the equipment is working;

(2) Check whether the peak value of motor working current exceeds the rated value;

(3) Check whether the inlet and outlet pressure exceeds 5% of the rated value;

(4) Check whether the temperature of lubricating oil is too high;

(5) Note that the oscillation check of water ring vacuum pump is performed according to GB 10889-89. Therefore, the precise equipment and trial work of vacuum pump are very important.

Careful operation is important. Therefore, it is necessary to strengthen the theoretical knowledge learning of vacuum pump for post operators, so that they can master the precise steps of starting, switching and stopping the pump. The precise operation of some auxiliary systems such as preheating and flushing is the same. Of course, the dynamic range of the pressure head and flow of the vacuum pump is relatively wide, but it should also be required to prevent the vacuum pump from working under the condition of long-time evacuation, low flow, pressure holding or overload, which will not only easily form the fatigue fracture of the pump shaft, but also reduce the power of the vacuum pump and add energy consumption.

Maintenance and predictive repair of water ring vacuum pump as scheduled

Any mechanical equipment has a certain life, a good vacuum pump is composed of many parts, therefore, it is extremely certain that the vacuum pump is out of order. Just as our private car needs to be maintained and repaired on schedule every year, in order to advance the working function of vacuum pump and extend the life cycle of vacuum pump, it is necessary to carry out predictive repair on schedule for vacuum pump. If the hidden trouble has not been detected and eliminated, its service life will be greatly improved.

According to the relevant research speech, in the past decade, many large enterprises have arranged vacuum pump repair workers to maintain their equipment on schedule and make predictive repair. On the one hand, predictive repair can determine the location and cause of the problem before the vacuum pump breaks out. It can repair the vacuum pump at the best time, so as to maximize the benefits of the whole equipment. On the other hand, after the prior repair method, can reduce the vacuum pump fault on the normal production and operation of the loss.
