First,WilwardISG single stage vertical pipeline pump, the reason for the motor body: the wrong connection will make the temperature rise rapidly when the equipment is used; In addition, there may be some phase to phase short circuits between stator windings, so when the situation is relatively minor, the motor is only in local places　　 First of all we need to know that submersible pumps generally operate in water. In fact,WilwardZD slurry pump, most of the pumps are suitable for conveying some relatively clean media, and their impellers are generally in a closed state. However, one of the media conveyed by sewage pumps mayWilward,　　It can be done. For example, before the test run, the motor and the main pump are separated from the test in the positive and negative directions, etc.　　 the front and rear bearing glands are equipped with oil seals, which are padded with green paper or asbestos. There is a gap of .- mm between the rear gland and the bearing.Gigg,　　 If the impeller of the pump is damaged after a long time of use, it will also lead to insufficient liquid supply for the pump.　　Do not exceed the rated current.　　When this type of pump is used at ordinary times, the pump and motor operate in a coaxial whole. When it runs, the motor shaft will drive the impeller of the pump to rotate and then at this time, the rotating force can be brought to the medium, so that

　　 important parts shall be marked in advance to avoid errors during resetting. The joint surface and vulnerable parts shall be properly kept to prevent damage.　　Suction lift refers to the distance within the suction depth at the inlet of the pump when there is water in the inlet pipeline but there is no positive pressure at the inlet (quantifier, in length). In fact, but the length is different. In a word, those with higher head have suction head　　 Prepare tools and materials: a set of metric box / open-end wrench, bearing puller (commonly known as triangle puller) magnetic dial indicator, outside micrometer, caliper, copper bar square ruler, screwdriver with handle, hammer, V-shaped irons of the same specification, clean kerosene, oil basin, cotton yarn, etc.Where to sell API,　　The solution to the excessive temperature of the water pump: when selecting the motor, it is necessary to select one that matches its power and speed. In addition, the cooling fan should be installed on the main shaft. It is also possible to appropriately increase the number of fan blades, but pay attention to adjusting the vacuum pump　　 When the power supply voltage is too low, because the pump is also widely used in many rural watering. In this case, it may be lower than the rated voltage, so the current in the stator winding will also be　　When the water level reaches, the frequency of the frequency converter drops, and the slurry pump operates at a low speed. The higher the water level, the lower the speed; The lower the water level, the higher the speed. At the same time, the water level signal is transmitted to the control cabinet so that the operators can timely understand the liquid level. Through this control, the circulation in the slag slurry pool is basically unchanged

　　 selection of raw materials for flow passage parts: the raw materials for flow passage parts of the pump can be selected according to the particle composition, particle size, shape, hardness, concentration, acid,WilwardPipeline pump body, alkali and other characteristics of the transported materials.Trustworthy,　　The purpose is to avoid water leakage of the pump, but the water seal may be damaged due to faults after being used for a period of time. Let&#;s learn how to replace the water seal.　　During daily use, we can observe, listen to and touch the submersible slurry pump according to the above methods, so as to judge whether there is a fault and the fault part of the slurry pump, and deal with it in time if any fault is found.　　 First remove the pump from the engine.Wilward,　　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.　　In the application of pumps, the first thing we think of is water. Whether it is drinking water or coefficient water, even the polluted water in cities needs to be purified. All these require its equipment to provide services for us. Without pumps, our basic survival is a problem.　　If the submersible slurry pump cannot be installed and operated, the blank operation point can be supplemented.
