Hato chandreVertical multistage centrifugal pipeline pumpIndustry highlights

　　 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. When　　When using the submersible slurry pump, we should do a good job in all aspects of commissioning and precautions. We also need to do a good job in protecting the equipment parts and some parts of the motor. Only in this way can we avoid the impact of water and other impurities entering the motorHato chandre,　　This series of slurry pumps have wide range, good cavitation and high efficiency. Flow passage parts have good wear resistance. Belt drive can be used to adjust the speed through the main adjusting pulley to adjust the flow and head.　　Friction resistance due to bearing and packing; Friction between impeller and water during rotation; The vortex of water flow in the pump, gap reflux, so it is impossible for the water pump to completely change the power input by the power machine into effective power, in which the constant active powerKibaha,　　 Assembly of rotor parts of submersible slurry pump Before assembly, apply a layer of lubricating oil on the mounting surface to protect the shaft hole from damage.　　Friction resistance due to bearing and packing; Friction between impeller and water during rotation; The vortex of water flow in the pump gap reflux, inlet and outlet impact and other reasons. A part of the power must be consumed, so it is impossible for the water pump to completely change the power input by the power machine into effective power, in which the constant active power　　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.

　　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.　　In order to improve the service life of the submersible sewage pump, that is, in case of leakage, overload, over temperature and other faults of the pump, it can give an automatic alarm and automatically shut down for maintenance. However, we believe that in the submersible sewage pump　　In fact, it can only be opened or closed, and the action time when opening and closing is relatively short.Product survey,　　During adjustment, firstly loosen the support cover, then compress the nut,Hato chandreSmall deep well pump, and then loosen the bearing seat. After adjusting the screw tighten the compression nut of the bearing seat evenly to make the assembly move towards the pump head. It is necessary to turn the trolley while tightening until the plate does not move. Rotate according to the pump operation　　Whether the pump is evacuated or overflowed, etc., and handle it at any time.　　 If the impeller of the pump is damaged after a long time of use, the tape shall be stretched twice, and then the three layers shall be folded in half with PVC tape to ensure that the winding part is not less than mm,Hato chandreCarbon steel explosion-proof pipeline pump, and the positions of the three joints shall be staggered for a certain distance in order to prevent short circuit.Installation materials,　　Friction. Because if the surface of the pump is smooth when it is used the equipment will consume less energy when it is used. Generally, the submersible slurry pump and impeller are sprayed with polymer composite materials for use　　The main and feature of self-priming pump is self-priming capacity. How to improve the performance of the pump and obtain large profits requires the following points: first, the discharge valve must be opened to start the self-priming pump, so that the gas can be discharged from the discharge port. Secondly, there should be enough liquid in the cavity of the self-priming pump, the rotor of the rotating pump shall be smooth and even, the outlet sluice valve shall be closed, and water shall be injected into the pump to ensure that the pump is full of water without air.Hato chandre,　　The development of submersible slurry pump is to adapt to increasingly complex working conditions, facilitate users to use,Hato chandreBaigang deep well pump, and its use mode is more flexible. And it fills a part of the gap in the application of slurry pump. When the submergence depth is deep and there is no better slurry outlet, that is, in the traditional slurry pump　　There are differences.　　Analysis of installation problems of slurry pump For bearings lubricated with thin oil, oil shall be added according to the oil level line of the oil standard before start-up. Add (HL hydraulic oil in winter and (hl hydraulic oil in summer. The bearing lubricating oil of the slurry pump shall be replaced once after continuous operation ( hours.
