　　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.　　Although the shaft seal occupies a small position in the pump, the normal operation of the pump is closely related to the shaft seal.Kustandir,　　Steam will produce air bags, which are harmful to water and seriously damage the vacuum suction. In order to immediately empty the pipe, avoid balloon accumulation. The suction pipe shall be a steep slope rising to the direction of water flow, rather than an immediate vertical rise, generally exceeding ., which should be the height of the top water pipe along the pump inlet　　In the mud pump, the axial force is mainly composed of the pressure difference force of the liquid effect on the impeller and the gravity of the whole rolling part. The effect direction of the two forces is the same, the liquid effect is on the auxiliary impellerSangli,KustandirLong shaft submerged slurry pump,　　Friction. Because if the surface of the pump is smooth when it is used, the equipment will consume less energy when it is used. Generally, the submersible slurry pump and impeller are sprayed with polymer composite materials for use　　In the application of pumps, the first thing we think of is water. Whether it is drinking water or coefficient water, even the polluted water in cities needs to be purified. All these require its equipment to provide services for us. Without pumps, our basic survival is a problem.　　Body. So that the pump can realize high concentration transmission without auxiliary devices. The unique sealing device can effectively balance the pressure inside and outside the oil chamber, so that the pressure at both ends of the mechanical seal can be kept balanced, which maximizes the reliable operation of the mechanical seal and greatly extends its service life

　　The purpose is to avoid water leakage of the pump, it will also lead to the burning of the motor.Inspection items,　　 After each use of the equipment, high-pressure water should be used to wash the pump and pipes. The washing can be stopped until the water has no impurities.　　 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.　　Then there are new structures, such as thermohydrodynamic seals, backup seals and asymmetric molded metal single wall bellows seals.

　　The purpose is to inject liquid higher than . MPa from the water seal ring to prevent gas leakage into the pump when the suction inlet of the submersible slurry pump is in a vacuum state. When the water pressure in the pump is higher than . MPa, the sealing fluid .-. MPa higher than the pressure in the pump can be injected to seal and reduce leakageInformation recommendation,　　Submersible slurry pump shaft seal type: packing, packing and auxiliary impeller seal, mechanical seal,　　Schematic diagram of vertical slurry pump II. Why does the demand for submersible slurry pump increase greatly? From the perspective of market demand,KustandirVertical centrifugal slurry pump, although the absolute number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum, mainly due to the convenience and flexibility mentioned above; In addition, for submersible slurry pump　　Its main features are as follows: the whole machine is a dry-type motor pump structure. The motor is protected by mechanical seal,KustandirVertical slurry 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　　It will generate heat, it will directly burn out the insulation; There may also be some faults in the ventilation system. At this time but when it is serious, it is necessary to check whether the fan of the submersible slurry pump is damaged or rotating
