It needs to be replaced in case of damage, insufficient spring pressure, breakage, etc.　　Do a good job of fixing to avoid the motor falling into the water and directly scrapping.Compastra asuya,　　The liquid level of slurry shall be higher than the inlet of pump.　　The direction of the differential pressure force is opposite, which can offset part of the axial force and prolong the service life of the bearing.Surigao City,　　If there is a standby pump it is recommended that the two pumps be used in turn. When the equipment is in use, it can pretend that a filter screen plays the role of filtration, so as to avoid a lot of impurities entering the equipment and causing pump jamming.　　 First, screw down the bolts on the side bearing pressure cap, and then remove the nuts used for the connection between the three parts: discharge section, stuffing box body and bearing body; Then screw off the round nut on the shaft, and successively install the bearing inner race, bearing gland and retaining sleeve　　The submersible slurry pump is a kind of submersible pump which is connected with the motor and works underwater at the same time. In addition, compared with horizontal slurry pump and vertical slurry pump, if the installation is correct, the smooth oil is appropriate, the repair is timely, and the delivery life will be long, the repair personnel should regularly repair the bearing components, check the condition of the bearings and the smooth oil, and regularly add or replace the smooth oil during the work, and the interval and write　　 Store in a well ventilated and dry place. If it is stored during idle period, the pump shall be slowly lifted from the water source and drained (especially in cold winter).　　Submersible slurry pump shaft seal type: packing, packing and auxiliary impeller seal, mechanical seal, etc.How many?,　　 When adding lubricating oil to the pump at ordinary times, the metering must be controlled, and the excess lubricating oil in the pump must be discharged and replaced regularly.　　The utility and durability of the utility model, so the polymer composite materials are generally used in production.　　 The rotor assembly is designed according to the actual situation, and the operation is more stable!

　　 Protective packing of shaft seal the shaft seal pump shall regularly check the sealing water pressure and water volume,Compastra asuyaFire deep well pump,Compastra asuyaSingle suction slurry pump, keep a small amount of cleaning water flowing along the shaft, regularly adjust the packing gland, check the packing and regularly replace the packing. The shaft seal water pressure and water volume shall meet the above (shaft seal inspection) requirements.Statistics,　　Therefore, the stator winding will be burnt out due to excessive temperature rise.　　Several common specifications and models.　　When in use it can drive the impeller to rotate so as to drive it to flow.Compastra asuya,　　 When stopping the operation of the submersible slurry pump, close the cock of the vacuum gauge and pressure gauge and the gate valve on the water outlet pipeline, and After that, cut off the power supply of the motor. If the temperature of the environment is low open the square plug at the lower part of the pump body to remove the remaining water to avoid frost cracking. During operation, the maximum temperature of the bearing shall not exceed ℃, and the quantity of calcium base grease used for lubricating oil bearing shall be the same as that of the bearing body　　At present, mechanical seals occupy an increasing share in the slurry pump seal market.　　Its main features are as follows: the whole machine is a dry-type motor pump structure. The motor is protected by mechanical seal,Compastra asuyaCarbon steel explosion-proof pipeline pump, which can effectively prevent high-pressure water and impurities from entering the motor cavity. In addition to the main impeller, it is also equipped with a mixing impeller, which can pump out the slag settled at the bottom after stirring into turbulence. impeller
