When it comes to pumps, you may be surprised at how much energy they use. They account for up to 10 percent of the energy used in the world. According to Grundfos Energy, two-thirds of centrifugal pumps today use up too much energy.
There are many reasons that your centrifugal vacuum pump may be using too much energy. Being able to troubleshoot the potential reasons why will help your company save money in the long run.
Wrong Pump Size
If your pump is either too large or too small, you may find that it uses too much energy. A too-small pump will struggle to keep up with the demands your facility places on it. You may also need to replace it sooner after wearing out.
On the other hand, your facility may not be using a too-large pump to its fullest capabilities. This can cause the excess energy to go to waste. Using a pump of the correct size can help you avoid wasting energy.
Improperly Adjusting Packing Gland
If you have overtightened the packing gland on your pump, your pump may not be efficient. However, the packing must leak a little to keep the seal area lubricated properly. When the area is not lubricated, the pump will have to work harder to keep up. Too-tight packing can also compress the shaft of the pump, which causes the shaft to drag.
To combat this problem, you should check to ensure that the installers properly set up the packing of the centrifugal pumps. You may need to ensure that enough drops are coming out in a certain amount of time.
You should ensure that the viscosity of the fluid in the pump is not too thick. It will take more energy if it is too thick because of the fluid resistance. You may need to resize your pump for your liquid’s viscosity.
The pump may use more electricity if it is rotating in the opposite direction that it was intended. Most pump impellers are not designed to run the opposite direction, so the pump must work harder if it is rotating in the wrong direction. You can check the power of the drive unit and ensure that it is installed properly.
