it has a great impact on the impeller of the equipment itself. So how to detect whether the equipment has cavitation during use?　　However,CoamoNon clogged pipeline sewage pump, 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 coalCoamo,　　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　　For example, it has a great impact on the impeller of the equipment itself. So how to detect whether the equipment has cavitation during use?Vila Nova de Gaia,　　 When starting the slurry pump, the outlet gate valve shall be (closed or slightly opened by /. Before starting the slurry pump, expand the pump inlet valve and close the pump outlet valve. Then start the pump. After the pump is started, slowly start the pump outlet valve. The size and speed of opening the pump outlet valve should be based on the fact that the pump does not vibrate and the motor　　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.　　About %), and motor power p=i × U indicates that high power and current will increase.

　　The first stage impeller of the pump is disassembled; It is also necessary to screw down the connecting nut between the water absorption section and the bearing body and the bolt on the bearing pressure connection, so that it is convenient for us to disassemble the bearing parts; When the shaft is pulled out from the suction section, the fixing nut on the shaft shall be　　At present, all screw pump manufacturers regard dry operation protection as a necessary unit for equipment procurement.　　What is the order.Analysis project,　　 The difference between the vertical slurry pump and the submersible slurry pump The working position of the vertical slurry pump is different. The vertical slurry pump is partially immersed in the pit and cannot be completely immersed in the liquid level. The submersible slurry pump can be completely immersed (including the motor part) below the liquid level; Use of motor for vertical slurry pump　　It is located in the middle, oil shall be added according to the oil level line of the oil standard before start-up. Add (HL hydraulic oil in winter and (hl hydraulic oil in summer. The bearing lubricating oil of the slurry pump shall be replaced once after continuous operation ( hours.

　　In fact, when the submersible slurry pump is blocked during use, it will not only have a certain impact on the working efficiency of the equipment during operation, but also cause serious damage to the equipment itself, so it is also a reminder that we are using it tooquality,　　The high-pressure water flows to the space occupied by the original bubble at a very high speed,CoamoIrrigation deep well pump, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressure　　There is no suction line. As the water storage tank is not deep enough and the suction pipe of the water pump is not deep enough, the inlet pipe of the water vortex is not deep enough. Water with a lot of gas. Destroy all normal water Self-priming pumps. To ensure sufficient depth of digestion and absorption of low watermark water. At that time, the depth was .~lm, and it was impossible to　　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,　　Therefore when the pump temperature is too high,CoamoCarbon steel explosion-proof pipeline pump, you don&#;t need to panic. You can quickly troubleshoot according to the above-mentioned reasons, so as to find out the root cause of the excessive temperature of the equipment in time, and then take relative measures to effectively solve it.　　 After each use of the equipment, high-pressure water should be used to wash the pump and pipes. The washing can be stopped until the water has no impurities.　　 Then tighten the compression nut on the packing gland evenly to make the liquid leak out in drops and pay attention to the temperature rise outside the packing chamber.
