The hardened mud layer collapses after softening,San Pablo Vertical centrifugal slurry pump, avoiding the phenomenon of burying the pump during use.　　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.San Pablo ,　　If it can be started and operated with lubricating water, or other types of bearings (such as polymer bearings) can be used according to the design or contract requirements.　　Adjustment. When using the submersible slurry pump,San Pablo Submersible sewage pump, accessories will be used and some auxiliary measures will be taken to improve the overall performance of the equipment and ensure the stable use of the equipment. Many users do not pay attention to these things when using them,San Pablo QJ submersible pump, which will cause equipment problems and affect work efficiency. So we&#;re usingTellitz,　　The higher the specific speed of submersible slurry pump, the smaller the allowable cutting amount of impeller diameter. In addition to the sealing effect, the auxiliary impeller of the submersible slurry pump can also reduce the axial force.　　 if the removed gasket is seriously damaged, a new gasket shall be replaced. The removed parts shall be cleaned with kerosene before assembly.　　Line direction pay attention to the direction of rotation. Then loosen the original compression nut of the bearing box of the slurry pump of the submersible pump, tighten the adjusting screw of the bearing box evenly, and then move the rotor assembly towards the motor. Then it is necessary to check the clearance with a feeler gauge δ, When δ= A (. ~ mm

　　 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.　　The treatment methods are as follows: Check the power supply voltage: if the voltage changes greatly, it is caused by unstable voltage and the use should be stopped immediately to prevent more serious consequences. Or install corresponding heat dissipation protection measures to protect the motor.　　 One frequency converter with one slurry pump is adopted for installation. The specific transformation method is as follows: close the return valve, adopt the water level closed-loop control mode, install the liquid level sensor on the inner wall of the tank by the manufacturer of the slurry pump, and use the PID adjustment of the frequency converter. WhenQuality improvement　　The above is the correct sequence of impeller disassembly of submersible slurry pump. Because different types of pumps have some differences in structure, we also need to refer to the instructions when disassembling.　　 First remove the pump from the engine.　　; In practical application, while the submersible slurry pump can be used directly without immersion which is convenient and flexible.

　　Schematic diagram of vertical slurry pump II. Why does the demand for submersible slurry pump increase greatly? From the perspective of market demand, although the absolute number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum, mainly due to the convenience and flexibility mentioned above; In addition, for submersible slurry pumpproduction,　　Auxiliary mixing or spraying device shall be equipped for easier operation. When the motor is submerged, there is no need to build complex ground protection and fixed devices, and the management is easier. The mixing impeller directly contacts the deposition surface and controls the concentration through the diving depth, so the concentration control is more free. Equipment directly submerged　　 Use a V insulation resistance meter to measure the insulation resistance between phases and phase to ground of the electric pump motor, the motor stator winding shall be dried, and the drying temperature shall not exceed ℃.　　 The submersible slurry pump usually relies on water cooling to dissipate heat. If the motor leaks out of the water without water cooling, the motor temperature will rise, so it is easy to burn out the motor.San Pablo ,　　 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.　　Troubleshooting: first increase the water pressure, then inject water into the pump body, and then start the pump. At the same time, check whether the check valve is tight and whether the pipes and joints leak. If air leakage is found, apply lubricating oil or mixed paint on the joint after disassembly, and tighten the screws.　　 Then reinstall the equipment on the engine and install the rubber hose.
