    Why do DC motors need water treatment

    Rehydration is generally a physiological requirement of living things, but when it comes to the use of machinery and equipment, we also need to replenish. When we use DC motors, we must also replenish it appropriately. The benefits are also obvious.

    In order to make the energy from the make-up water to the DC motor work on the gas effectively and improve the efficiency, the make-up water should be entered at the end of the work of the liquid on the gas, that is, the highest point of the compression chamber, so that the unit obtains sufficient energy. Work can be resumed at the next cycle. The purpose of this work is to:

    (1) The loss of the supplementary liquid ring with the gas flowing out of the exhaust hole.

    (2) Seal the end surface gap between the motor body and the impeller.

    (3) The heat of compression generated by the exhaust of compressed gas.

    (4) Cooling and lubricating packing, packing gland and other parts.

    If there is a large amount of supplementary water, too much water occupies a part of the gas space (it can also be considered that the thickness of the water ring increases), which reduces the gas volume and exhaust pressure. Too much water will also increase power consumption, reduce efficiency, and generate noise and vibration. Makes the operation of the DC motor very unstable, and periodically, a large amount of water is ejected from the exhaust hole in a pulsating manner.

    If the amount of make-up water is small, the compression heat in the DC motor cannot be exhausted sufficiently, so that the temperature of the water ring and the upper gas will rise, and the gas volume and vacuum will decrease. If the amount of water is too small, the loss of the water ring cannot be replenished, which not only further reduces performance, but also stops working because the water ring cannot form. From the above, we have concluded that, in order to improve the working efficiency of DC motors, it is necessary to replenish water appropriately, not too much or too little.

    Therefore, there are certain standards for how much, how, and when to replenish DC motors. It is not just like this. The amount of water will affect the use of DC motors, so we must pay special attention.
