How To Reduce The Chance Of Pump Jams In Submersible Slurry Pumps?

When the submersible slurry pump is working, the pump needs to be placed on land, the suction pipe needs to be placed in water, and the pump needs to be started.The water pump is placed in the water, so it must be fixed.Otherwise, the motor will fall into the water and be scrapped.Moreover, since the length of the long shaft is generally fixed, the installation and use of the pump is more troublesome, and the application situation is subject to many restrictions.If there is a backup slurry pump, it is best to use two pumps in turn.If the pump is stuck, you can only repair the pump.You can add grids to the water inlet to prevent too many impurities from entering the pump, and the chance of getting stuck will be much smaller!Submersible slurry pumps are divided into two aspects: electricity and machinery.For machinery, the main thing is to get out the previous maintenance records and compare them.We should understand the power of each slurry pump motor and have a certain understanding of its control system.A slurry pump with mechanical seal must ensure the supply of shaft sealed water.It is strictly forbidden to operate without water, otherwise the mechanical seal will be burned.　The correct use of submersible slurry pumps will extend their service life.During use, the medium concentration should not be too high to avoid damage to the overflow area. The whole machine is a dry motor pump structure.The motor adopts mechanical seal protection, which can effectively prevent high-pressure water and impurities from entering the motor cavity.In addition to the main impeller, there is also a stirring impeller.The slurry pump can stir the slag precipitated at the bottom into turbulent flow and extract it.Main channel components such as impellers and stirring impellers are made of high wear-resistant materials, which are wear-resistant, corrosion-resistant, non-blocking, and have strong sewage discharge capabilities, and can effectively pass through large solid particles.Leakage during static testing of slurry pump installation.After the installation and commissioning of the mechanical seal, a static test is generally required to observe the leakage.If the leakage amount is small, it is mostly a moving ring or a static ring, and there is a problem with the sealing ring; when the leakage amount is large, it means there is a problem between the friction pairs of the dynamic and static rings.Based on the preliminary observation of the leakage and the determination of the leakage position, manually turn the observation.If the leakage volume does not change significantly, there will be problems with the sealing of the static and dynamic rings; if the leakage volume changes significantly during rotation, it can be concluded that there will be problems with the friction pairs of the static and dynamic rings; if the leakage medium is sprayed axially, there will be the most problems with the static ring sealing ring.If the leakage medium is sprayed around the water-cooled hole or leaks from the water-cooled hole, the static ring seal is mostly invalid.After the product is used for a period of time, special attention should be paid to whether the electrical insulation meets the requirements.If repair or use is improperly found, the insulation resistance is low, the cable is damaged, or the machine is rusted, difficult to operate, or the starting current is increased, it should be repaired or maintained in time to prepare for emergencies and prevent safety accidents or further damage to the machine.
