cornerNon clogged pipeline sewage pumpResearch and development significance in practical field

　　Work, no noise and vibration, and the site is cleaner.　　The fruit is also bad; When the axial flow pump is used its water output is relatively large, but the head is not too high so the effect of using the submersible slurry pump in many plain areas is also relatively good; The water output and head of the mixed flow pump are actually derived from onecorner,　　 Operation management of sewage pump operation management of submersible pump adjust the liquid level to make the water pump operate at the best operating point. After the equipment is selected, the intersection of the characteristic curve of the water pump and the characteristic curve of the device is the best operating point.　　 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 sleeveUnion-de-Reyes,　　Do a good job of fixing to avoid the motor falling into the water and directly scrapping.　　 Pipeline layout: Firmly support the water pipe and drain pipe to prevent the force of the pipe from acting on the submersible slurry pump.　　 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 itself

　　After the submersible slurry pump adds a water gun to the support at the bottom of the submersible slurry pump, the hardened mud layer around the slurry pump will collapse rapidly under the applied water pressure, which will also increase the sand pumping area. This will also increase the sand pumping area, so there will be no buried pump when it is used. However,　　 Change the oil: if the oil contains water, drain it, change the oil, seal the gasket, and then tighten the screw plug.　　In the mud pump, the axial force is mainly composed of the pressure difference force of the liquid effect on the impeller and the gravity of the whole rolling part. The effect direction of the two forces is the same, the liquid effect is on the auxiliary impellerDiscount,　　 Then replace the pulley and pump cover plate and tighten the fixing nuts.　　Submersible slurry pumps are mainly used in mining, metallurgy,cornerSmall deep well pump,cornerSelf priming non clogging sewage pump, coal, environmental protection, electric power and other industries to transport corrosive solid particle slurry. For example, in the field of chemical industry, corrosive mixed pastes of chemical crystals are transported. Electric ash removal, coal washing plant slurry transportation, etc. Submersible slurry pump blade　　There are many types of submersible slurry pumps available in the market, and different pump models have different performance and application fields. Therefore although the pump has a wide range of applications, if its model is not correctly and reasonably selected, its application effect will be great

　　In fact, but it is adjustable. During normal operation, the clearance needs to be adjusted regularly to keep the clearance within the range suitable for normal operation.Latest consultation,　　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, so we should follow the correct steps to connect.　　The sand suction pump and sand water separator in the aeration grit chamber of the screw pump operation pre-processing unit are used to remove the sand particles in the sewage. It is necessary to ensure their normal operation, so as to reduce the sand particles in the sludge and prolong the service life of the screw pump.　　 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. Whencorner,　　Then there are new structures, such as thermohydrodynamic seals, backup seals and asymmetric molded metal single wall bellows seals.　　 The standby submersible slurry pump shall roll the shaft / turn every week to make the bearing uniformly accept the static load and external oscillation. The building structure in the water pump room shall be reconstructed. Sound absorbing and isolating plates shall be installed around the wall and on the top of the machine room and fixed with light steel keel; The connecting holes between the machine room and other rooms are tightly blocked,　　 If the impeller of the pump is damaged after a long time of use, it will also lead to insufficient liquid supply for the pump.
