The hardened mud layer collapses after softening, avoiding the phenomenon of burying the pump during use.　　 First remove the pump from the engine.San Francisco,　　 It is not allowed to operate the electric pump at high lift for a long time, and try to control it within the range of the proposed use lift, install the liquid level sensor on the inner wall of the tank by the manufacturer of the slurry pump adopt the water level closed-loop control mode, and use the PID adjustment of the frequency converter. WhenKanbe,　　It needs to be replaced in case of damage, swelling and deformation, insufficient spring pressure, it is necessary to timely adjust the clearance between the impeller and the front guard plate. When adjusting the impeller clearance, first stop the pump, loosen the bolts pressing the bearing box, loosen the adjusting nuts, make the bearing components move forward, and roll the shaft by hand to press the　　Submersible slurry pump shaft seal type: packing, packing and auxiliary impeller seal mechanical seal, etc.

　　 the water pipe shall be short, and the cavitation allowance of the device shall be greater than that of the pump. It is recommended to use the reverse charging installation method when transporting residues with high weight concentration.　　 For protection during operation, a temperature sensor is generally installed on the stator to detect the temperature of the stator. In case of dry operation due to lack of medium, the wear of the stator and rotor will be very large, and the temperature will increase with friction,San FranciscoVertical multistage centrifugal pipeline pump, further increasing the wear. therefore　　The above four methods can be used to detect whether the submersible slurry pump has cavitation, because if the equipment is in use, it will have a great impact on the operating efficiency. Even if the cavitation time is long, it will also have a certain impact on other parts of the equipment. Sometimes submersible slurry pumpquality index,　　Troubleshooting: first increase the water pressure, then inject water into the pump body, and then start the pump. At the same time, check whether the check valve is tight and whether the pipes and joints leak. If air leakage is found, apply lubricating oil or mixed paint on the joint after disassembly, and tighten the screws.　　The supply of shaft seal water must be ensured. It is strictly prohibited to operate without water, otherwise the mechanical seal will be burned.　　In fact, the pumps I am going to talk about here have a wide range of uses. Pumps are required for both civil and military purposes, as well as for advanced technologies, especially in the mining, chemical, metallurgical and other industrial sectors. It is a widely used general mechanical equipment. Most pumps are corroded or severely corroded

　　 The working properties of the two pumps are also different. Because the sewage pump is driven by a motor, it generally has good voltage impact resistance. The submersible pump is of the type of quick opening and quick closing so it usually uses some small Flow and small pressure.Price,　　However, there is also a disadvantage of using the auxiliary impeller sealing system, that is, it takes some energy on the auxiliary impeller of the submersible slurry pump, which is generally about %. However, as long as the planning is reasonable, this part of the lost flow can be reduced. The slurry pump is mainly applicable to electric power, metallurgy and coal　　From the working principle, Li is a centrifugal pump. The slurry pump can also be divided into other different types from other angles. Let&#;s see from what angle Panshi pump can classify the slurry pump: first, the suction inlet of the slurry pump　　The pump can often be selected according to the specific requirements of lift, flow and liquid delivery. The flow range of the delivered liquid is - L / s, the pressure range is .- MPa and the diesel engine speed range is - rpm. Features: water pump, high automation and performanceSan Francisco,San FranciscoVertical centrifugal slurry pump,　　In addition to the method, materials shall be selected comprehensively according to the nature of corrosive medium, anti cavitation theory, corrosion mechanism of water pump and stress characteristics. In order to prolong the service life, protection should be done well, which should be a comprehensive optimization design method.　　 Why does the demand for submersible slurry pumps increase greatly? From the perspective of market demand, although the number of submersible slurry pumps has not exceeded that of vertical slurry pumps, the application market of submersible slurry pump is also better than that of vertical pump　　There are differences.
