HiroshimaLong shaft submerged slurry pumpWhat issues should be considered when choosing

the motor can add a variety of protection devices such as water inflow detection and overheating

　　Balance of.　　According to the user&#;s requirements,HiroshimaPipeline pump, so that the product can operate safely for a long time under adverse working conditions.Hiroshima,　　The horizontal slurry pump is a cantilever centrifugal slurry pump, which is suitable for conveying abrasive or corrosive slurry. The structures of all types of horizontal slurry pumps are similar except that the pump head (including pump body, pump cover, impeller, when the submersible slurry pump is blocked during use shaft seal part and transmission part　　In fact, 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 tooCsongrad,　　It is longer and saves production cost. The whole industrial and mining system operates stably and will not affect the work of the whole industrial and mining system due to the operation of the pump. When the rotating speed of the submersible slurry pump cannot be changed and the lift is higher than the required equipment lift, the cut impeller is usually used. The cut is　　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.　　Potential energy, pumping water up high. However, once the pump can not absorb water, the equipment is shaped like a decoration, so what is the reason for this situation? How to solve it?

　　Start the priming pump. Moreover, 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　　(c) The minimum ambient air temperature is - ℃.　　Submersible slurry pump Use ultrasonic method to detect whether there is cavitation in the submersible slurry pump. This method is often convenient for re detection. Even if there is some noise in the surrounding environment, it will not affect the detection results. Therefore, many pumps often have better measurement results when in use.Customer first,　　 First of all, we need to choose equipment with formal certificates when making choices. We must avoid buying some obsolete or inferior products. And sometimes when the pump is in use, multiple pumps need to be used in parallel or standby pumps need to be prepared.　　Schematic diagram of vertical slurry pump II. Why does the demand for submersible slurry pump increase greatly? From the perspective of market demand, although the absolute number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum, mainly due to the convenience and flexibility mentioned above; In addition, for submersible slurry pump　　Under the action of auxiliary devices,HiroshimaSmall deep well pump, 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 use

　　When the pump is not in use, the pump shall be lifted away from the water source in time to drain the accumulated water in the pump,　　Different process requirements: the motor used in the vertical slurry pump is an ordinary vertical motor, which has no waterproof . The motor of the submersible slurry pump and the pump shaft are coaxial. The motor shall be waterproof and sealed. The motor and the pump body can invade underwater at the same time.　　Automatic pump failure: cause: A. whether the frequency converter has abnormal symbols; b. Whether the actual pressure is higher than the set pressure.　　 the water pipe shall be provided with a gate valve to regulate the pump working point. The valve shall be installed as close to the pump outlet as possible. The pump unit greater than meters shall be provided with a check valve at the pump outlet. In case of sudden shutdown,HiroshimaHH slurry pump, it is necessary to prevent damage to flow passage components caused by water hammer.Hiroshima,　　What?　　 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 ℃, and the quantity of calcium base grease used for lubricating oil bearing shall be the same as that of the bearing body　　 It may be that the motor power of the water pump is too large, the working current is too large, and the heat generation is too large, resulting in the high temperature of the vacuum pump.
