Old cityZD slurry pumpIn electrical safety

　　Only in this way can its service life be extended to a large extent.　　Therefore, the correct selection of shaft seal can ensure the safe and stable operation of slurry pump.Old city,　　It is necessary to set up a protection system, which can protect the operation of the electric pump. But this is not the key to the problem. The protection system is just a remedy after the pump fails. It is a passive method.　　 selection of raw materials for flow passage parts: the raw materials for flow passage parts of the pump can be selected according to the particle composition, particle size, shape, hardness, concentration, acid, alkali and other characteristics of the transported materials.Haibu,Old citySelf priming slurry pump wholesale,　　 The gas inadvertently entered in the equipment is discharged and good sealing performance is ensured.　　Then it can enter into the volute pump housing. Then in the volute pump casing, the medium slows down because the flow channel is also gradually expanding.　　Submersible slurry pump it fills the gap in the application of slurry pump. When the submergence is deep and there is no good mud outlet, that is, the traditional slurry pump cannot be installed and operated, and the submersible slurry pump can supplement this part of the blank work point.

　　Let the medium containing some solid particles generate a certain flow rate,Old cityCirculating hot water pipeline pump, so that the equipment can drive the solid to flow when it is in use, so that the slurry can be transported. In terms of the principle of the submersible slurry pump, it is actually quite simple　　 Check the water pump: it is possible that the selection of the water pump is not matched with the motor, the use time and times should be strictly limited, the correct thermal protection should be selected, and　　 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.Encyclopedic knowledge,　　Third, the whole industrial and mining system operates stably, which has no waterproof . The motor of the submersible slurry pump and the pump shaft are coaxial. The motor shall be waterproof and sealed. The motor and the pump body can invade underwater at the same time.

　　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 corrodedInterpretation and observation　　The structure of the submersible slurry pump will be more intuitive. First, the equipment will use centrifugal force to drive the liquid from the impeller to the outer edge and obtain energy, and then leave the edge of the impeller at a higher speed　　When assembling the motor and water pump departments below grade ,Old cityQJ submersible pump, firstly, tighten the nuts evenly between the water inlet joint and the contact plane from the upper part to the bearing seat, install the coupling pump shaft, fixed studs and lock rings, fix the impeller and conical sleeve on the pump shaft with a damp cylinder, and install the guide housing and impeller　　Friction resistance due to bearing and packing; Friction between impeller and water during rotation; The vortex of water flow in the pump, inlet and outlet impact and other reasons. A part of the power must be consumed, so it is impossible for the water pump to completely change the power input by the power machine into effective power, in which the constant active powerOld city,　　 Structural features and working principle qsz submersible slurry pump is a coaxial integration of water pump and motor. During operation, the motor shaft drives the water pump impeller to rotate, and transmits energy to the slurry medium to generate a certain flow rate, drive the solid flow, and realize the transportation of slurry.　　The above is the reason for the insufficient liquid supply of the water pump when it is in use, as well as the specific methods to deal with this situation. We should pay attention to the regular inspection of the equipment during normal use to ensure that it is in use　　 Protective packing of shaft seal the shaft seal pump shall regularly check the sealing water pressure and water volume, 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.
