Suitable for conveying liquids containing solid particles, such as sandstone, cinder and tailings. So what are the requirements for its work? Let&#;s understand briefly.Andorra-La-Vella,　　 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.　　 one method is to use ultrasonic method to detect whether the equipment has cavitation. 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 tend to have better measurement results when in use.　　After that, before starting again, check whether the impeller rolling is normal and whether the bearing assembly compression bolts are tightened, and then start the pump.

　　First, let&#;s talk about the familiar vertical slurry pumps. Here we refer to ZJL and SP submerged slurry pumps. Strictly speaking, the submersible slurry pump is also a vertical slurry pump, because its axis is basically vertical when it works, extending the service life of the pump.　　The equipment is integrated with the oil cooler, with compact layout.

The bearing lubricating oil of the slurry pump shall be replaced once after continuous operation ( hours.　　With the continuous development of slurry pump technology, submersible slurry pump appears in response to market demand. It is especially suitable for the depth at which the vertical slurry pump cannot operate. The underwater part of the vertical slurry pump is generally not more than m, and of course it can be more than. For example, the maximum design depth of our company&#;s underwater slurry pump can reach m, but such underwater depth is not the best operating depth of this kind of pump, so it will lead to the unreliability of the operation of the vertical slurry pump from time to time.　　The pump can often be selected according to the specific requirements of lift, flow and liquid delivery. The flow range of the delivered liquid is - L / s, the pressure range is .- MPa, and the diesel engine speed range is - rpm. Features: water pump, high automation and performance

　　Reasonable.　　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　　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?Customer first,　　The non service life of the equipment is not as long as possible. If it is not used for a long time,SonghuPipeline pump body, it will not only easily corrode the parts, but also reduce the service life of the parts.　　Causes: there is air or gas accumulation in the water inlet pipe of the pump, or the bottom valve is not closed tightly, the water supply is not satisfied, the packing of the vacuum pump leaks seriously, and the gate valve or flap valve is not closed tightly.　　 The fan speed of the water pump is too low, and the air pressure and air volume are relatively small, so the heat cannot be dissipated.
