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.　　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.Arouca , which can form a three-dimensional protection for the fire pump, including voltage overvoltage and undervoltage protection, current overcurrent and undercurrent protection, overload protection, phase loss protection, overheating protection, etc. this　　At the same time, the supporting pipelines in the pump room shall be provided with vibration isolation elasticity.Partido de Morón,Arouca Centrifugal slurry pump,　　Start the priming pump. Moreover,Arouca Small deep well pump, due to the structural limitations of the submersible slurry pump, the motor needs to be placed on the water surface for use during operation, and then the pump needs to be placed in the water for use. Therefore, the submersible slurry pump must be　　Different process requirements: the motor used in the vertical slurry pump is an ordinary vertical motor, and the middle section including the guide vane; in addition, remove the impellers middle sections and guide vanes at other levels in the same way until the submerged slag slurry　　Pipeline pump, belonging to the category of centrifugal pump, is a single-stage centrifugal pump with standing structure. Because the layout design of its water pump inlet and outlet is relatively special, they are all located on the same straight line, and their inlet and outlet diameters are the same, the overall description is similar to a section　　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 leakageFree consultation,　　Different installation requirements: the vertical slurry pump needs to be fixed, while the submersible slurry pump does not need to be fixed. It can directly invade into the liquid for operation.　　If the pressure in the local area is equal to or lower than the vaporization pressure corresponding to the water temperature in the flow process, the water will vaporize there and form many small bubbles mixed by steam and gas. The cavitation phenomenon is due to the bubble action when these small bubbles flow from the low-pressure area to the high-pressure area in the water pump,　　It should be /-/ between. When the packing is worn, the packing gland can be properly pressed. If it is worn too much,Arouca Carbon steel explosion-proof pipeline pump, it should be replaced. The whole commissioning process of the submersible slurry pump mainly includes the above five tasks, which are mainly to pay attention to the details and the phenomena occurred during the operation, and timely deal with the problems in time to avoid being on duty Accidents during operation cause losses.

　　Balance of.Honest service,　　So it has a process of water diversion and exhaust. There are usually two ways to inject water into equipment. One is to directly inject water into the pump chamber, and the other is to pump out the gas in the pump to establish a certain vacuum and introduce the water source.　　In addition to conventional accessories, ordinary long shaft pumps can also manufacture deep well pumps with different al characteristics according to the special requirements of customers. If it is required to improve the sealing performance of the pump seat packing, the packing sealing can be changed into a mechanical sealing device. If there is backpressure water at the wellhead, a sealed pump seat can be used. If required in none　　Normal operation. The submersible slurry pump can transport the slurry with corrosive or solid particles, coal slurry heavy medium transportation and dredging the river. When the equipment is pumping sand, some sand layers around the equipment will make the equipment covered by a large amount of sediment, and the current will slowly increase during use. Well, we should chooseArouca ,　　At present
