When it comes to proper maintenance, it’s important for owners of liquid ring vacuum pumps to know what signs of trouble to look for and the appropriate action to take. With proper maintenance, not only will your equipment perform optimally but also provide many years of reliable service. Of course, the best scenario is to start by working with a leader among liquid ring vacuum pumps manufacturers. Ultimately, you’ll have fewer problems with superior-quality equipment.
Keep in mind that in addition to purchasing equipment from one of the leading liquid ring vacuum pumps manufacturers, it’s crucial that you become familiar with the operating and maintenance guide provided. You want to use that as a reference, not only for properly maintaining the equipment but also for identifying any potential problems, or ‘Troubleshooting’.
For liquid vacuum pumps, the following represent key steps required for proper maintenance:
Be sure to monitor the temperature of the bearings and grease them at the specified intervals in the specified amounts, as well as monitor vibration and lubricant levels if medium like oil is used. Similar to oil in an automobile, the lubricant in liquid ring vacuum pumps should appear clean, meaning it doesn’t have any signs of frothing, discoloration beyond what is described as normal in the manual. As for vibration, you can expect some of that during normal operation. However, if you notice significant vibrating, you could have an issue and should check if extra vibration pads are needed or baseplate is secures. Excess weight or forces on piping can also cause vibration. If bearings’ temperature becomes too hot, it could indicate that the pump’s failing and can either be because the bearing itself has failed, the couplings are mis-aligned presently, or the pump has been cavitating for too long. IN this case, adjust the anti cavitation valve to allow vacuum relief.
The condition of the shaft seal is another important part of maintenance on liquid vacuum pumps. Normally, you wouldn’t notice any signs of wear or leakage. As with vibration, you can expect to see a small amount of leakage but at no time should it exceed 40 drops per minute. Check the mechanical seal area for leakage and replace if needed. Of check the mechanical seal lubrication if the pump calls for this and the flow to the seals is inadequate.
Another aspect of maintenance has to do with the vibration of the bearings. Often, this occurs because the alignment of the pump changed. This is also caused by a change in the valves situated in the suction or discharge lines. Ultimately, if the bearings fail, you’re going to see an increased vibration level.
One additional thing worth noting as far as maintenance goes has to do with the pressure in the discharge of liquid ring vacuum pumps. If you begin to notice a gradual decrease in the pump’s head pressure, this may be due to a widening of impeller clearance. Usually, making the necessary adjustment to the clearance is all it takes to allow the pump to operate optimally.
