Selection of pipeline diameter: the selection of pipeline shall consider the one-time purchase cost long-term operation cost and operation reliability.　　 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 powerJamsa,　　Correct the main shaft of the water pump and adjust the position of the water pump and the motor relatively.　　 We must choose to consider the actual use situation when making the selection, because there will be some difference between the marked head when using and the head when using. This is because the pipe itselfChepo,JamsaLong shaft submerged slurry pump,　　Body. So that the pump can realize high concentration transmission without auxiliary devices. The unique sealing device can effectively balance the pressure inside and outside the oil chamber, so that the pressure at both ends of the mechanical seal can be kept balanced, which maximizes the reliable operation of the mechanical seal and greatly extends its service life　　 if the removed gasket is seriously damaged a new gasket shall be replaced. The removed parts shall be cleaned with kerosene before assembly.　　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

　　 Before starting the submersible slurry pump, the rotor of the rotating pump shall be smooth and even, and water shall be injected into the pump to ensure that the pump is full of water without air.　　The ability of dirt passing through makes it safer to use.　　 If the power cord is not well contacted, it will also lead to the burning of the motor.Word of mouth recommendation,　　Commodity.　　 If there is abnormal sound inside the slurry pump and there is no water, it is likely that the equipment may have air infiltrating into it when absorbing water, which will cause abnormal sound inside the pump, and then at the same time,JamsaBooster pipeline pump, the impeller is damaged or the impeller is damaged　　There is no need to equip auxiliary mixing or spraying equipment, and the operation is simpler. The equipment is directly submerged for operation, without noise and vibration, and the site is cleaner.

　　Rotate in the rolling direction until the friction between the impeller and the front guard plate stops, then use the adjusting bolt to move the rotor backward, record the forward and backward movement gap,JamsaVertical slurry pump, evenly distribute it between the front and rear guard plates of the impeller until the gap between the impeller, the front guard plate and the rear guard plate is flat, stop, and tighten the two dust discs and fasten them on the shaft. adjustmentProject scope,　　 selection of flow: single suction pump or double suction pump shall be selected according to the flow; single suction pump or multi suction pump shall be selected according to the lift.　　Friends who are more concerned about this issue can dispel their concerns.　　 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 motorJamsa,　　 If the hot water within ℃ is recommended, the hot water pump must be used, and the external tap water shall be connected for cooling during operation, otherwise the motor will not be burned due to too high medium temperature.　　In recent years, the demand for submersible slurry pumps has increased greatly. In many fields, 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?
