The slurry pump of underground pump can also work normally.　　Second, the service life of the flow passage parts of the pump is relatively long, saving production costs.Washington DC,　　 Constantly observe the instrument, check the electrical equipment, and measure the insulation resistance every half a month. The resistance value shall not be less than . megohm.　　 The rotor assembly is designed according to the actual situation,　　The hardened mud layer collapses after softening, avoiding the phenomenon of burying the pump during use.　　With the continuous development of slurry pump technology, submersible slurry pump appears in response to market demand. It is especially suitable for the depth at which the vertical slurry pump cannot operate. The underwater part of the vertical slurry pump is generally not more than m, and of course it can be more than. For example, the maximum design depth of our company&#;s underwater slurry pump can reach m, but such underwater depth is not the best operating depth of this kind of pump, so it will lead to the unreliability of the operation of the vertical slurry pump from time to time.　　When in use, it can drive the impeller to rotate so as to drive it to flow.

　　The seal cannot bear the water pressure at this depth. Once the water leaks, the motor will not work normally, resulting in damage to the submersible slurry pump. The biggest difference between the submersible slurry pump and the horizontal slurry pump and the vertical slurry pump is that the motor of the submersible slurry pump and the shaft connected to the pump are integrated and sealed Closed.　　 Shaft seal part auxiliary impeller shaft seal: through the impeller action of a reverse centrifugal force prevent the slurry from leaking out. When the positive pressure at the inlet of the pump is not greater than % of the pressure at the outlet of the pump, the single-stage pump or the first stage pump in series can adopt the auxiliary impeller shaft seal, and the auxiliary blade shaft seal is not required　　After that, the secondary and tertiary pumps can be started successively until the final stage pump. After all the series pumps are started the outlet valve of the final stage pump can be gradually opened. The speed of opening the valve should be controlled by the fact that the pump does not vibrate and the motor of any stage does not exceed the rated current.Inspection standard,　　 drainage and water injection with vacuum equipment: the self exhaust of centrifugal pump is the same as the negative pressure exhaust of vacuum pump, so the water ring vacuum pump is used for exhaust to achieve the of water inlet.　　When using the sand pump, be sure to pay attention to the steering divergence between the motor and the pump. The sand pump has an arrow on the pump to mark the main steering. After the power supply is connected, run the pump without load. Check whether the motor operates normally. During operation, be careful not to exceed the bearing on the pump support to avoid　　It needs to be replaced in case of damage, swelling and deformation,Washington DCLong shaft submerged slurry pump, insufficient spring pressure, breakage, 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.total cost,　　 Move the sand pumping site frequently. When the pump pumps sand at a fixed position and drops to a certain height, lift the submersible slurry pump and move it to the adjacent position of the previous sand pumping place to continue pumping sand, so as to move the sand pumping place back and forth for sand pumping, so that the sand pumping area in this area forms a honeycomb　　To sum up,Washington DCSmall deep well pump, we can know that the submersible sewage pump is both a submersible pump and a sewage pump, depending on what the user is used to calling it in use.　　 It is also possible that the fan blades of the pump are few and the air volume is insufficient,Washington DCSubmersible pump can pump sewage, resulting in poor heat dissipation effect.Washington DC,　　The fruit is also bad; When the axial flow pump is used, its water output is relatively large, but the head is not too high, so the effect of using the submersible slurry pump in many plain areas is also relatively good; The water output and head of the mixed flow pump are actually derived from one　　The above is about how to replace the water seal of Boshan submersible slurry pump. In addition to the water seal, some parts of the pump are relatively easy to be damaged, so we need to replace them regularly during use　　Check whether it needs to be replaced.　　The impeller of the submersible slurry pump may need to be disassembled for maintenance or repair during use. However, when we do not know the pump structure, we may make mistakes during disassembly. Let&#;s take a look at the correct disassembly of the impeller
