You can quickly troubleshoot according to the above-mentioned reasons when the pump temperature is too high, 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.　　There are main reasons why the submersible pump is 'sick'. The rotation direction of the motor is wrong: please ensure that the rotation direction of the motor is correct before using the submersible sewage pump. Even if water is produced by reverse rotation, the output of water is small and the current is large. Direction rotation will cause irreversible damage to the motor winding　　How to avoid this situation when the equipment is in use.Focus on Development,　　The slurry pump should be 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 and prospecting on board; What are the advantages of the submersible slurry pump? The advantage of the submersible slurry pump is that it is convenient and flexible,KisaranSubmersible sewage pump, easy to operate and submerged　　What is the order.　　 In addition the noise method directly detects the noise of the equipment in the detection process, but this measurement will also be affected by the surrounding noise, so in fact, this measurement is not very accurate.

　　Many users, including new practitioners of slurry pumps, often fail to distinguish the difference between submerged vertical slurry pumps and submerged slurry pumps. The names of submerged and submerged slurry pumps seem similar,　　Through the introduction, we learned that the submersible slurry pump can be used to transport slurry when it is used at ordinary times. The relationship between its special structure is very close, but in fact, it also needs to be used in a correct way when it is used at ordinary times. Only in this way can　　The main and feature of self-priming pump is self-priming capacity. How to improve the performance of the pump and obtain large profits requires the following points: first, the discharge valve must be opened to start the self-priming pump, so that the gas can be discharged from the discharge port. Secondly, there should be enough liquid in the cavity of the self-priming pump, otherwise it will not　　Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s.　　The difference between the shaft power P and the effective power PE is the power loss in the pump, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, which is measured by η Indicates.Kisaran,　　Avoid airborne sound transmission; Ensure the airtightness of machine room doors and windows. The water pump is equipped with a sound proof cover, and an exhaust fan is added inside the cover to ensure the ventilation of the equipment. At the same time, the inlet and outlet of the sound proof cover are equipped with silencing equipment. A vibration isolation platform is installed at the bottom of the water pump for foundation vibration reduction to isolate the vibration generated during the operation of the water pump　　Many people do not know much about the packing and sealing of equipment because of the equipment of mass and energy. Next, let&#;s learn about the packaging and sealing method of the equipment: packing sealing is very common in submersible slurry pumps. This method has good sealing performance, and effectively reduces the wear of the host and anti vibration kinetic energy　　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 choose

　　Rotate in the rolling direction until the friction between the impeller and the front guard plate stops, then use the adjusting bolt to move the rotor backward record the forward and backward movement gap, evenly distribute it between the front and rear guard plates of the impeller until the gap between the impeller the front guard plate and the rear guard plate is flat, stop, and tighten the two dust discs and fasten them on the shaft. adjustment　　Second, the service life of the flow passage parts of the pump is relatively long, saving production costs.Singapore,　　.　　 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.　　 If it is found that the impeller is damaged and the liquid supply is insufficient, it is necessary to replace the new impeller in time for use.
