Nahiyatash shinafiyah HotelSelf priming slurry pump wholesaleFollow the principle of construction

　　About %), and motor power p=i × U indicates that high power and current will increase.　　 Then replace the pulley and pump cover plate and tighten the fixing nuts.Nahiyatash shinafiyah Hotel,　　QW (WQ) non clogging submersible sewage pump QW (WQ) non clogging submersible sewage pump IV. the submersible sewage pump uses V power supply, which should be three-phase power supply. If the submersible pump has only two-phase power supply, it will not start. In this case,Nahiyatash shinafiyah HotelSingle suction slurry pump, a professional electrician should be asked to use a clamp on ammeter or a submersible pump control　　Cavitation of the pump is caused by water evaporation of the pump. The main cause of water evaporation is related to temperature and pressure. Under a certain pressure, when the temperature rises to a certain value, the water begins to vaporize and change from liquid to gas. On the contrary, at a certain temperature, the pressure drops toSektevkar　　 Why does the demand for submersible slurry pumps increase greatly? From the perspective of market demand, although the number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum. The main reason is that the above-mentioned use is convenient and flexible; In addition, the application market of submersible slurry pump is also better than that of vertical pump　　 When starting the slurry pump the outlet gate valve shall be (closed or slightly opened by /. Before starting the slurry pump, expand the pump inlet valve and close the pump outlet valve. Then start the pump. After the pump is started, slowly start the pump outlet valve. The size and speed of opening the pump outlet valve should be based on the fact that the pump does not vibrate and the motor　　Strong strength and other advantages. It is widely used as a sealing device for various pumps. Place a water seal ring at the bottom of the packing box, and then place the filler.

　　Pressure. Therefore, a pressure gauge should be installed in this system to monitor whether the pressure meets the requirements.　　 After the electric pump has been used for many times,Nahiyatash shinafiyah HotelWear resistant slurry pump, it is necessary to put the electric pump into clean water and run it for several minutes to prevent sediment in the pump and ensure the cleanness of the electric pump.　When using the submersible slurry pump, the equipment may be burned out. The main reason for this phenomenon is improper operation. How should we prevent the burning out?Production department, and conduct hydrostatic test if necessary.　　Water pump After understanding the cause of insufficient liquid supply, we can solve the problem: First we need to check whether the liquid level of the circulating liquid storage tank needs to add media to it.　　 First, screw down the bolts on the side bearing pressure cap, and then remove the nuts used for the connection between the three parts: discharge section, stuffing box body and bearing body; Then screw off the round nut on the shaft, and successively install the bearing inner race, bearing gland and retaining sleeve

　　When the slurry pump is working, the pump needs to be placed on land,Nahiyatash shinafiyah HotelPipeline pump, the suction pipe in water, and the pump needs to be started. Due to the structural limitations of the mud pump and submerged slurry pump, the motor needs to be placed on the water surface during operation, the motor will fall into the waterService first,　　 There may also be mechanical failure of the pump, such as serious damage to the bearing of the pump, so that the bore will be 'swept' when the stator and rotor rub against each other, or the impeller will be stuck due to impurities such as water and grass when the pump pumps water　　Installation method: coupling can be used for direct connection, or belt pulley can be used for connection with belt.　　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.Nahiyatash shinafiyah Hotel,　　In recent years, submersible slurry pumps have replaced vertical slurry pumps. What are the differences between the two? Let&#;s yze.　　 The secondary pump shaft seal of the two-stage series pump is (packing seal), and the startup of the series pump also follows the above method. Only after the first stage pump is started, the submersible slurry pump can open the outlet valve of the last stage pump (the opening size is based on the motor current of the first stage pump as the rated power　　Water flow into the bearing damages the bearing.
