Considering the working principle and performance characteristics of the eddy current pump, the outlet throttle regulation mode consumes the most power in operation. Thus, it can be seen that it is of great significance for users to adopt reasonable adjustments during the service life to save energy in production. However, when the relative flow rate of the swirl pump changes little or the regulation range is small, the energy consumption of the swirl pump changes little no matter which method is adopted. That is to say, the adjustment method has no obvious effect on energy saving. Usually, when the adjustment depth increases, the energy-saving effect will gradually become obvious. Therefore, in this case, we need to carefully select the appropriate adjustment mode, so that in the process of using the eddy current pump, we can achieve the greatest energy-saving benefits. In this case, the variable speed curve is close to the ideal curve.

Therefore, the frequency conversion speed regulation mode is superior, especially the energy-saving scheme of the frequency conversion speed regulation is the best, but the frequency conversion device needs to be added. Especially medium and small capacity variable frequency speed regulation can also be tried. Of course, not only the initial investment cost, but also the reliability and use cost should be considered during the service life. During the working period, swirl pump shutdown operation is also more important. Especially in some emergencies, we need an emergency shutdown. For example, in the process of unit trial operation, if it is found that the equipment suddenly appears violent vibration, and exceeds the tripping value, or there are scratches or abnormal frictional sound inside the body, the machine should be stopped in time. After the completion of production tasks, normal shutdown mode should be adopted. At this time, the operation steps are as follows: slowly open the exhaust valve (or exit bypass valve), gradually close the exhaust valve; slowly close the intake throttle to 20-25 degrees; 3. Press the stop button, pay attention to the abnormal phenomena in the process of swirl pump shutdown; stop oil supply after the swirl pump device stops for a period of time. In addition, there are many turbofan equipment in the structure design. The fan cap is specially designed for heat dissipation, which is equivalent to the heat dissipation device of motorcycle engine, and greatly reduces the working temperature of the fan.

Therefore, the equipment can run stably for a long time, reduce high temperature impact and prolong service life. It is worth noting that as the users of the scroll pump, we should not only master the operation rules of the equipment, but also master some common sense of maintenance equipment. If there are some minor faults in the operation of the equipment, it can be repaired by itself without the need for professional maintenance personnel. Moreover, self-repair can save a lot of maintenance time. So what basic maintenance knowledge do users need to master?
