Sign in perhaps register 。

and the pump and motor of the equipment used in time are the same shaft so　　Do not exceed the rated current.Hanover,　　The harm and avoidance of the reverse rotation of the slurry pump impeller the reverse rotation of the slurry pump impeller may cause the slurry pump impeller to fall off at least, or cause the damage of the whole pump at most. The reverse rotation of the slurry pump impeller mainly has the following hazards: The slurry pump impeller falls off. The connection between the slurry pump impeller and the pump shaft is a one-way screw　　The application of pumps involves all aspects of work and production, and the types of pumps are also diverse. Some of the same pump have several names, and some of the names are very similar, which makes it difficult to distinguish. Today,HanoverSplit vertical pipeline pump, we will introduce the submersible pump and the submersible slurry pump. Is there any difference between the twoBabruysk,　　 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.　　Then it can enter into the volute pump housing. Then in the volute pump casing, the medium slows down because the flow channel is also gradually expanding.　　 The gas inadvertently entered in the equipment is discharged and good sealing performance is ensured.

　　 Impeller protection in order to ensure the operation of the submersible slurry pump, it is necessary to timely adjust the clearance between the impeller and the front guard plate. When adjusting the impeller clearance, first stop the pump, loosen the bolts pressing the bearing box, loosen the adjusting nuts, make the bearing components move forward, and roll the shaft by hand to press the　　The key to the problem should be to fundamentally solve the problems of pump sealing and overload, which is a more active method. Therefore, which greatly improved the pump seal　　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 besafety requirements ,　　 A vent pipe is installed at the bottom of the pump, so that when the pump is buried underground, water will be injected into the bottom of the slurry pump through the vent pipe, so that a sand water mixture will be formed at the bottom of the slurry pump, so that the slurry pump can be started normally. The advantage of this approach is that even if　　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, is easy to use, and effectively reduces the wear of the host and anti vibration kinetic energy　　 determination of model: for water pump or pump with physical and chemical medium similar to water,HanoverVertical heavy-duty slurry pump, it is necessary to go to the relevant product catalog or sample, and make correction according to the performance table or performance curve of the model to see whether the normal working point falls in the priority working area of the pump.

　　Some of them are OK. For irrigation and other purposes, in fact, we choose to use larger flow. Let&#;s take a look at the method of selecting pumps.investment　　The utility and durability of the utility model, so the polymer composite materials are generally used in production.　　 within the estimated installation depth, the minimum inner diameter of the well is mm　　The effective power is also called output power, which is expressed by PE. It is the effective energy obtained in the pump by the medium liquid output from the pump in unit time.Hanover,　　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,HanoverQJ submersible pump, 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　　Pump, sewage submersible pump and seawater submersible pump.　　 When stopping the operation of the submersible slurry pump, close the cock of the vacuum gauge and pressure gauge and the gate valve on the water outlet pipeline, and After that cut off the power supply of the motor. If the temperature of the environment is low, open the square plug at the lower part of the pump body to remove the remaining water to avoid frost cracking. During operation, the maximum temperature of the bearing shall not exceed ℃
