First,Santo DomingoRubber lining submerged slurry pump, the reason for the motor body: the wrong connection will make the temperature rise rapidly when the equipment is used; In addition, there may be some phase to phase short circuits between stator windings, so when the situation is relatively minor, the motor is only in local places　　 the front and rear bearing glands are equipped with oil seals, which are padded with green paper or asbestos. There is a gap of .- mm between the rear gland and the bearing.Santo Domingo　　 water quality: fine sand; Zhongsha; River and river water　　After the submersible slurry pump leaves the factory, there is generally only outgoing cable, and the user needs to connect it separately during installation. If the connection is wrong, it will seriously affect the normal operation of the pump, so we should follow the correct steps to connect.El-Palmar,　　 When the slurry pump fails to absorb water during operation, it may also be because the bottom valve is not opened. At this time, 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　　Is called cavitation phenomenon.

　　Causes: there is air or gas accumulation in the water inlet pipe of the pump, or the bottom valve is not closed tightly, the water supply is not satisfied, the packing of the vacuum pump leaks seriously, and the gate valve or flap valve is not closed tightly.　　The key to the problem should be to fundamentally solve the problems of pump sealing and overload, which is a more active method. Therefore,Santo DomingoNon clogged pipeline sewage pump,Santo DomingoVertical slurry pump, we applied the hydrodynamic seal technology of the auxiliary impeller and the non overload design technology of the pump to the submersible sewage pump, which greatly improved the pump seal　　Then there are new structures, such as thermohydrodynamic seals, backup seals and asymmetric molded metal single wall bellows seals.production,　　Strong strength and other advantages. It is widely used as a sealing device for various pumps. Place a water seal ring at the bottom of the packing box and then place the filler.　　 If there is abnormal sound inside the slurry pump and there is no water, it is likely that the equipment may have air infiltrating into it when absorbing water, which will cause abnormal sound inside the pump, and then at the same time, the impeller is damaged or the impeller is damaged　　Head refers to the energy obtained from the pump by the unit weight of liquid output by the pump, the effective power of the pump: the equation is PE= ρ GQH (W)= γ QH (W)

　　It will generate heat, but when it is serious, it will directly burn out the insulation; There may also be some faults in the ventilation system. At this time, it is necessary to check whether the fan of the submersible slurry pump is damaged or rotatingDiscount,　　Through the introduction, we learned that the submersible slurry pump can be used to transport slurry when it is used at ordinary times. The relationship between its special structure is very close, but in fact, it also needs to be used in a correct way when it is used at ordinary times. Only in this way can　　Belt drive shaft seal: the pump seal can be divided into three types: packing seal, auxiliary impeller seal and mechanical seal. The packing seal and the secondary impeller seal will drip during the operation of the pump. Mechanical seal can make no water leak.　　Flexibility. The equipment has advanced structure, strong sewage discharge capacity, excellent material selection and strong corrosion resistance. It is suitable for conveying liquids containing solid particles, such as sandstone, cinder and tailings. So what are the requirements for its work? Let&#;s understand briefly.Santo Domingo,　　 First of all, we need to know that submersible pumps generally operate in water. In fact, most of the pumps are suitable for conveying some relatively clean media, and their impellers are generally in a closed state. However, one of the media conveyed by sewage pumps may　　In addition to the method, materials shall be selected comprehensively according to the nature of corrosive medium, anti cavitation theory, protection should be done well, which should be a comprehensive optimization design method.　　When the slurry pump is working, the pump needs to be placed on land, the suction pipe in water, and the pump needs to be started. Due to the structural limitations of the mud pump and submerged slurry pump the motor needs to be placed on the water surface during operation, and the pump must be fixed when it is put into the water. Otherwise, the motor will fall into the water
