Vacuum Pumps: Common Problems and Tips
Vacuum pumps are durable and heavy equipment but may experience problems that need repair. Below are some common problems you may encounter. Knowing what to look for will aid in knowing what needs repair and when to get help.
Leaking
Leaking is a common problem with vacuum pumps. Carefully observe the pump to find the location of the leak. If it is possible to find the exact location and the quantity of the leakage, track it. This will make it easier to get help over the phone and to get a better cost estimate.
Unusual Noises
When a pump is unusually noisy and making sounds you don’t normally hear, a foreign object could be trapped in the pump. An overload of water or high horsepower may also cause noisy pump operation. Unusual noise may also be due to cavitations or bearing failure.
Vibration
System problems can cause vibration problems, but the vibrating may be due to the pump as well. Check the piping and separators to see if they may be the cause of the vibration. Constant carryover and excessive seal water to the pump may also cause vibration. Another common cause of pump vibration is due to the tension and alignment of the coupling or V-belt.
Failure to Start
When the pump fails to start, first check the power supply to make sure it is connected properly. If everything is set up correctly, an electrical failure in the system may be the cause of the failure to start. Failure to start may also be caused when the pump is flooded with oil. Excessive low temperatures may also keep the vacuum pump from starting.
While these are common problems that need repair, other problems may occur. When you encounter a problem with your vacuum pump, there are many things that can be checked and easily fixed. Other problems are more complicated and require the help of a professional who knows and specializes in repairing vacuum pumps.
