The liquid ring vacuum pump is a reliable and durable solution for challenging process applications. Our liquid ring vacuum pump is the first design and has been the industry leader ever since.
Through continuous research and product development, we continue to deliver high-quality compressors and product upgrades that perform well even under more demanding conditions while reducing our total cost of ownership.
Performance and proven reliability required? Look at the following questions.
How to check the cylinder of liquid ring vacuum pump?
Liquid ring vacuum pump cylinder inspection is necessary behavior, why say so? After the equipment is used for a period of time, we need to carry out a certain overhaul, among which, the overhaul of the cylinder is particularly important, so let’s see how to overhaul.
1. Measure the roundness and cylindricity of the cylinder of the liquid ring vacuum pump, and determine the boring cylinder or replace it according to its wear degree;
2. The roundness and cylindricity of the cylinder shall comply with relevant regulations;
3. The inner surface of the cylinder shall be free of cracks, sand holes, scars, grooves and other defects, and the surface roughness shall be 1.6.
4. No cracks or leakage are allowed in the cylinder jacket;
5. The diameter of the rear cylinder of the hammer liquid ring vacuum pump shall not increase more than 2% of the original size, and the thickness of the cylinder wall shall not exceed 1/12 of the original wall thickness.
Correct maintenance of the liquid ring vacuum pump cylinder will be more conducive to the use of the vacuum pump, but also to extend its life. In this way, the equipment can work better for people!
liquid ring vacuum pumps four common faults
Failure 1. Difficult turning
Turning difficulty is one of the frequent faults of the liquid ring vacuum pump, but the main reason for turning difficulty is that the liquid ring vacuum pump did not enter the working state for a long time after leaving the factory, resulting in the phenomenon of rust on the end face of the liquid ring vacuum pump. Usually in the face of turning difficulties can be in the liquid ring vacuum pump pump chamber into the oxalic acid for immersion. If it is difficult to turn in the use of the state, in addition to the use of oxalic acid immersion, but also need to clean the water temperature and scale ring vacuum pump
2. Abnormal starting sound
Liquid ring vacuum pump in a long time after the use, there will be abnormal start sound fault, in the event of this kind of fault should check the power supply voltage and wire connection is normal, if no abnormal can open the lid of the liquid ring vacuum pump to remove impurities operation. If rust is found in the liquid ring vacuum pump, the rust remover should be added. In addition, if excessive working fluid is found in the sewage outlet, the abnormal starting sound can also be caused. Appropriate amount of working fluid can be discharged to try to repair
3. The temperature of the liquid ring vacuum pump is too high
For the fault of excessive temperature of the liquid ring vacuum pump, if the reason is the inlet temperature of the working fluid is too high or the supply of working fluid is too small, first of all, it is necessary to reduce the temperature of working fluid or increase the supply of working fluid. In addition, too high suction temperature will also cause too high liquid ring vacuum pump temperature, which can be solved by condensing condensable gas at the inlet of the liquid ring vacuum pump
4, motor temperature overheating
Overheating temperature of the liquid ring vacuum pump in motor to motor open phase, the exhaust pipe, the impeller parts inspection, such as insufficient water supply also can lead to motor overload temperature is too high, water supply shall be restored to normal range is usually under normal operation, the possibility of liquid ring vacuum pump failure is low, if appear afore-mentioned fault phenomenon can according to the method for debugging and maintenance, if you can’t solve shall timely inform the manufacturer
