　　Pump, sewage submersible pump and seawater submersible pump.　　The submersible slurry pump may be blocked when it is used at ordinary times. In particular, some equipment is frequently used at ordinary times, but the maintenance work is not done well when it is used, so it will be blocked after being used for a period of timeFeldkich,　　Check the three-phase current with an ammeter on the control panel. If the phase power supply is found to be insufficient, the power supply of the submersible pump shall be turned off immediately. Check whether the cable connector connection point and power switch contact are in poor contact and whether they are the main line. Check whether the circuit wiring is broken or loose, or whether the fuse is damaged or burnt out　　During adjustment, firstly loosen the support cover then compress the nut, tighten the compression nut of the bearing seat evenly to make the assembly move towards the pump head. It is necessary to turn the trolley while tightening until the plate does not move. Rotate according to the pump operationDelhi,　　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　　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 leakage　　Second, the power used is not matched, so the motor temperature will be too high after long-term overload operation; In addition, frequent startup during use will also lead to fever, so I

　　For example, in the market, for example, the sweeping pump, some of which have a depth of more than meters, it is not suitable to use a vertical slurry pump under such a working condition, but it is extremely easy to use a submersible slurry pump.　　The self-priming pump is a self-priming centrifugal pump. It has the advantages of compact structure,FeldkichSubmersible non clogging sewage pump, convenient operation, stable operation, easy maintenance, high efficiency, long service life, and strong self-priming capacity. There is no need to install the bottom valve in the pipeline. Before operation, it is only necessary to ensure that a certain amount of liquid is stored in the pump. Different liquids can　　 add water with manual pump. Some pump owners have their own hand pumps. They can also buy or manufacture their own small hand pumps. The gate valve shall be installed at the water inlet. After closing the valve, inject a small amount of water into the water compressor to divert water. When the hand pump discharges water, it means that the pump is fullquality,　　 for screws that are too tight or rusted for a long time, the nut can be lubricated with kerosene prepared in advance, or the nut can be gently knocked with a wooden hammer and then removed. This method can also be used in slurry pumps and other places.　　 If it is found that the impeller is damaged and the liquid supply is insufficient, but also reminds the pump designers and producers that in addition to good working conditions, the pump should also have good corrosion resistance, high reliability and long service life. The pump shall be designed in addition to the conventional design method of fluid mechanics

　　Under the action of auxiliary devices,FeldkichZD slurry pump, it can transport the slurry, and because the sealing device itself is special, it can also ensure the internal and external balance of the submersible slurry pump during transportation, so that the pressure at both ends of the equipment can be balanced during normal usemiddleman　　Compared with the vertical slurry pump, the application market is also larger. In addition to the existing industrial and mining applications of the vertical slurry pump, the submersible slurry pump can also be used as a mobile slurry pump, such as sand pumping on board, prospecting, etc; Submersible slurry pump assembly workshop III. what are the advantages of submersible slurry pump　　For /g-g gravel pump, it is necessary to remove the impeller removal ring and rotate the impeller in the opposite direction.　　It will generate heat, but when it is serious, it is necessary to check whether the fan of the submersible slurry pump is damaged or rotatingFeldkich,　　Troubleshooting: first increase the water pressure, then inject water into the pump body, and then start the pump. At the same time,FeldkichTwo stage slurry pump, 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.　　 Inspection before installation: Check the specification size and quality of thick and thin accessories.　　 The fan speed of the water pump is too low, and the air pressure and air volume are relatively small, so the heat cannot be dissipated.
