The submersible slurry pump can be completely immersed (including the motor part) below the liquid level; Use of motor for vertical slurry pump

　　Ensure that the service time will be extended when it is used. We all know that the submersible slurry pump needs to optimize its structure to meet the requirements of use because the medium it transports is relatively special. The structure has been optimized toHighly recommended,　　 Next, it is necessary to check the water seal. If the water seal is bakelite and the wear is not too serious, and then grind the water seal of Boshan submersible slurry pump flat or turn it over for use. However, if the thrust rubber water seal is used, when　　 When the slurry pump operates, it rotates at a high speed, and the components of the slurry pump have a heavy weight. Therefore, once it reverses, the force will directly push the impeller to the outside, and the impeller collides with the sheath and guard plate. If the speed is high, the force ratio is low　　In order to ensure the demand for water and electricity for production and living, many units, hotels and residential areas in various provinces and cities in China have purchased it and generators.

Such as ore slurry transportation in metallurgical concentrator, coal slurry and heavy medium transportation in coal washing plant, river dredging,BaodingSmall deep well pump, river dredging, etc. In chemical industry　　When the submersible slurry pump works, the pump needs to be placed on land, the suction pipe needs to be placed in water, and the pump needs to be started. Due to special structural requirements, when the slurry pump motor is submerged in the water, the slurry pump and submerged slurry circulating pump need to be placed above the water surface, otherwise the motor will fall into the waterBaoding,　　Directly immersed in the liquid, most coal washing conditions and power plant conditions are used more. For users who do not know much about the slurry pump, looking at the slurry pump series, they feel very similar in many places, or even no difference. In fact, they are basically the same in essence. The difference is in the details, compared with　　 Why does the demand for submersible slurry pumps increase greatly? From the perspective of market demand, although the number of submersible slurry pumps has not exceeded that of vertical slurry pumps it has a rapid development momentum. The main reason is that the above-mentioned use is convenient and flexible; In addition, the application market of submersible slurry pump is also better than that of vertical pumpTala,　　 If the power cord is not well contacted, it will also lead to the burning of the motor.　　Troubleshooting: first increase the water pressure, then inject water into the pump body, 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.　　The pump should be divided into two aspects: electricity and machinery. As for machinery, you can compare the previous maintenance records. The second is electricity. You should know the power of each pump motor and have a certain understanding of its control system. Slurry pump with mechanical seal

　　The operating environment is different: the key difference between the submersible slurry pump and the vertical slurry pump lies in diving. During the operation of the vertical slurry pump, some parts intrude into the pit and cannot completely invade the slurry; The submersible slurry pump can completely penetrate below the slurry level.　　 other requirements (cable, control box, liquid level control etc.)　　Let the medium containing some solid particles generate a certain flow rate, so that the equipment can drive the solid to flow when it is in use, so that the slurry can be transported. In terms of the principle of the submersible slurry pump, it is actually quite simplemiddleman,　　The hardened mud layer collapses after softening, avoiding the phenomenon of burying the pump during use.　　Is called cavitation phenomenon.　　 Impeller protection in order to ensure the operation of the submersible slurry pump it is necessary to timely adjust the clearance between the impeller and the front guard plate. When adjusting the impeller clearance, loosen the bolts pressing the bearing box, loosen the adjusting nuts, make the bearing components move forward, and roll the shaft by hand to press the

　　Be sure to choose a pump that is more suitable for use.agent　　; In practical application, the submersible slurry pump is developing rapidly with its unique advantages. The vertical slurry pump needs to be fixed and installed in use, while the submersible slurry pump can be used directly without immersion, which is convenient and flexible.　　 Shaft seal part auxiliary impeller shaft seal: through the impeller action of a reverse centrifugal force, prevent the slurry from leaking out. When the positive pressure at the inlet of the pump is not greater than % of the pressure at the outlet of the pump, the single-stage pump or the first stage pump in series can adopt the auxiliary impeller shaft seal, and the auxiliary blade shaft seal is not required　　If there is a standby pump, it is recommended that the two pumps be used in turn. When the equipment is in use,BaodingHH slurry pump, it can pretend that a filter screen plays the role of filtration, so as to avoid a lot of impurities entering the equipment and causing pump jamming.Baoding,　　Generally, the diving depth of the submersible slurry pump is not more than meters, and the operation is reliable. Why not more than meters? This is the crucial technical point of the submersible slurry pump, because the current sealing technology in China is more than meters, not because the slurry pump has a problem, but because　　 the water pipe shall be provided with a gate valve to regulate the pump working point. The valve shall be installed as close to the pump outlet as possible. The pump unit greater than meters shall be provided with a check valve at the pump outlet. In case of sudden shutdown, it is necessary to prevent damage to flow passage components caused by water hammer.　　 The slurry pump mainly aims at conveying flow, so the flow meter (meter) shall be installed in the operation monitoring system as far as possible to monitor whether the flow meets the requirements at any time; In the pipeline system, slag flushing system and pressure filtration dehydration system equipped with hydrocyclone, certain

　　 The fan speed of the water pump is too low, and the air pressure and air volume are relatively small, so the heat cannot be dissipated.　　Through the introduction,AtbasarFire deep well pump, we learned that the submersible slurry pump can be used to transport slurry when it is used at ordinary times. The relationship between its special structure is very close, but in fact, it also needs to be used in a correct way when it is used at ordinary times. Only in this way canAtbasar,　　During normal operation the impeller of the slurry pump becomes tighter and tighter as it turns. The more it is used, the easier it will operate. However, if the slurry pump reverses, it will directly cause the impeller of the slurry pump to fall off. The slurry pump must be disassembled and then re inspected, installed and tested.　　At the same time, the supporting pipelines in the pump room shall be provided with vibration isolation elasticity.Group,　　Normal operation. The submersible slurry pump can transport the slurry with corrosive or solid particles, coal slurry heavy medium transportation and dredging the river. When the equipment is pumping sand, and the current will slowly increase during use. Well we should choose　　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, for submersible slurry pump　　The submersible slurry pump is developed to adapt to the increasingly complex working conditions and facilitate the use of users. Its use mode is more flexible. The equipment has advanced structure, wide flow passage, strong sewage discharge capacity, excellent material selection and strong corrosion resistance. Suitable for conveying liquids containing solid particles, such as sandstone, cinder and tailings. So what are the requirements for its work? Let&#;s understand briefly.

　　The water slurry pump is a widely used equipment. Many people are interested in the water diversion and exhaust method of the slurry pump equipment. Now let&#;s talk about the water diversion and exhaust method of the submersible slurry pump: the submersible slurry pump needs to pump out the water to form a vacuum, and then supply water,　　From the working principle, Li is a centrifugal pump. The slurry pump can also be divided into other different types from other angles. Let&#;s see from what angle Panshi pump can classify the slurry pump: first, the suction inlet of the slurry pump　　Pump sewage submersible pump and seawater submersible pump.where,　　Rotate in the rolling direction until the friction between the impeller and the front guard plate stops,AtbasarSubmersible non clogging slurry pump, then use the adjusting bolt to move the rotor backward, record the forward and backward movement gap, 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, etc., and handle it at any time.Recommendation and consultation,　　 When the power supply voltage is too low, the pump will be overloaded, because the pump is also widely used in many rural watering. In this case, it may be lower than the rated voltage, so the current in the stator winding will also be　　That is, first, check whether the equipment operation noise is reasonable; second, check whether the alarm unit has leakage and overheating alarm signals; third, check whether the vibration of the guide rod is normal; fourth, record the flow and current of the water pump operation. If there is any problem in the above inspection, the cause shall be yzed and reported in time.　　 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,　　 If the head of the submersible slurry pump is too low or the head is higher than the practical condition, the flow will be large and the current will rise. At this time, the outlet valve can be turned down to increase the resistance to control the current.　　In this way, a smooth surface can be formed on the surface.　　For example, concentrate and tailings are treated in the concentrator, ash and slag are removed from the power plant,AtbasarVertical multistage centrifugal pipeline pump, slime and dense medium coal are transported in the coal preparation plant, and slurry is transported in coastal river mining operations. The weight concentration of the treated slurry is: mortar %, ore slurry %; It can be operated in series according to the needs of users.
