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.　　 Then tighten the compression nut on the packing gland evenly to make the liquid leak out in drops, and pay attention to the temperature rise outside the packing chamber.Dartmouth,　　 Determine the head h. After the flow is determined, determine the inlet and outlet pipe diameters of the pump, and determine the head. In the actual selection, the resistance coefficient of the pipeline is often too large. In addition, when selecting the pump model, a head margin is added, resulting in　　 First of all, let&#;s understand the causes of insufficient liquid supply: If the liquid level stored in the circulating liquid storage tank is lower than %, then insufficient liquid supply will occur when it is in use. Or the pump adds too much lubricating oil, which leads to accumulationMasyaf,　　 A vent pipe is installed at the bottom of the pump, so that when the pump is buried underground,DartmouthWater well pipeline pump, water will be injected into the bottom of the slurry pump through the vent pipe, so that a sand water mixture will be formed at the bottom of the slurry pump, so that the slurry pump can be started normally. The advantage of this approach is that even if　　It is occasionally found that there is insufficient liquid supply when using, so what are the reasons for this situation and how to deal with it.　　After the submersible slurry pump leaves the factory, there is generally only outgoing cable, and the user needs to connect it separately during installation. If the connection is wrong, it will seriously affect the normal operation of the pump, so we should follow the correct steps to connect.

　　Different installation requirements: the vertical slurry pump needs to be fixed, while the submersible slurry pump does not need to be fixed. It can directly invade into the liquid for operation.　　Belt drive bearing assembly: the bearing assembly of this series of pumps adopts cylindrical structure, which is convenient to adjust the clearance between the impeller and the front and rear guard plates, and can be removed as a whole during maintenance. The bearing is lubricated with grease.　　In addition to the main impeller inside the equipment, a set of impeller for mixing will be added at the bottom of the equipment, so that the equipment can be used without itsPrice,　　Potential energy, pumping water up high. However, once the pump can not absorb water, the equipment is shaped like a decoration, the submersible slurry pump has many advantages,DartmouthSubmersible non clogging sewage pump, especially filling the gap in the application conditions of the traditional horizontal and vertical slurry pumps. At present, the application of the submersible slurry pump is gradually becoming more and more widespread, and the market recognition is continuously improving, especially meeting the needs of deep-water sand pumping and dredging. At present, the depth can reach meters.　　 install the front pump shaft first and then the rear bearing for the slurry pump of the filter press of the cylindrical bearing box.

　　Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s.　　The difference between the shaft power P and the effective power PE is the power loss in the pump, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, which is measured by η Indicates.Scheme customization,　　 First of all, let&#;s understand the causes of insufficient liquid supply: If the liquid level stored in the circulating liquid storage tank is lower than %, then insufficient liquid supply will occur when it is in use. Or the pump adds too much lubricating oil, which leads to accumulation　　In order to maintain the original treated water volume without increasing the number of water pumps, the liquid level in the storage tank can be increased by adjusting the floating ball in the liquid tank. After the liquid level in the storage tank is increased, the he QE curve of the device must move to the right. At this time, the head at the intersection of the two curves becomes smaller and the flow remains　　What is the order.Dartmouth,　　What?　　Fourth, model selection parameters: outlet diameter flow,DartmouthWQ submersible pump parameters, dust, motor power, impeller speed, pumping rate, maximum particle and weight.　　 A vent pipe is installed at the bottom of the pump so that when the pump is buried underground, water will be injected into the bottom of the slurry pump through the vent pipe, so that a sand water mixture will be formed at the bottom of the slurry pump so that the slurry pump can be started normally. The advantage of this approach is that even if
