CNSME PUMP's Vertical Froth Pumps

　　This can reduce the wear of the slurry pump and is worth collecting　　It is very necessary to reduce the wear of the slurry pump, which can effectively reduce the cost of mineral washing.From the design and production of pumps to the application of pumps in production, there are issues and requirements that should be paid attention to. In summary, there are roughly the following points: How to reduce the wear of slurry pumps?1. The design method should comply with relevant theories. In water conservancy design, since the pump conveys a solid-liquid mixture, the characteristics of the solid-liquid mixture should be taken into account during design and the two-phase flow theory should be used for design.At the same time, new scientific research and theories should be used to make the shape at the overflow component more similar to the movement trajectory of the slurry, so as to reduce the impact and friction of solid particles on the slurry pump, thereby reducing wear.2. Improve the structure. Taking reasonable parameters to design the structure and selecting the blade import diameter D will have a great impact on wear capacity and efficiency.For parts that are prone to wear in the slurry pump, in addition to improving in theoretical design, the structure should also be improved. The parts should be made into replaceable parts as much as possible. At the same time, during structural design, it should be better considered for the convenience of replacement.3. Do a good job in daily maintenance, such as: (1) Keep the equipment clean, dry, oil-free, and leak-free.(2) Check whether the pump's running sound is normal, whether there is vibration or leakage every day, and deal with problems in a timely manner if they are found.(3) Check whether the oil level in the bracket is suitable every day. The correct oil level is near the oil level line and must not exceed 2mm.(4) It is strictly forbidden to work in the state where the slurry in the pool is evacuated, because the slurry pump operates in the evacuated state not only vibrates violently, but also affects the life of the pump.(5) Each pump is marked with the size of large solid particles that are allowed to pass through. It is strictly forbidden to enter human metal objects and large solid particles that exceed the allowable passage of the pump.In addition, it is strictly forbidden to enter flexible substances such as rubber, cotton yarn, and plastic into the pump to avoid damaging the overflow components and blocking the impeller and runner, causing the pump to not work normally.(6) Check frequently whether the pressure and flow rate of shaft sealing water and cooling water are appropriate.You can use the method of checking the opening degree of the shaft seal valve or detecting the temperature of the packing box. When the temperature is high, it means that the water supply is insufficient.For pumps that use grease to lubricate fillers, oil should be refueled 1-2 times a day to ensure that the slurry pump is in a good lubricating state.

What are the importance of the application field of submersible slurry pumps? Let me briefly analyze it for you: Submersible slurry pumps can be used in mining industries, and transport abrasive solid particles in the power, metallurgy, coal, environmental protection and other industries.Such as the transportation of slurry in metallurgical ore dressing plants, the hydraulic ash removal of thermal power plants, the coal slurry and heavy media transport of coal washing plants, the dredging of river channels, and the siltation of river channels.In chemical industry, some aggressive slurries containing crystals can also be transported.At present, 80% of the control of slurry pumps are used in mineral processing plants in the mining industry.Due to the despicable ore preliminary selection conditions, the slurry pump has a wide and low service life in this stage.Of course, the abrasive properties of different ores are also different.Although the purpose of submersible slurry pumps is ordinary, precise use is very important.Due to the limitations of its title, some people in the industry misunderstand this. In fact, impurity pumps, dredging pumps, dredging pumps, etc. are all at the boundary of the use of slurry pumps.During the use of slurry pumps, we must pay attention to the correct design, accurate calculation, and appropriate selection. These points are very important.How can we solve the problem of blockage during use?Many customers think this is a very complicated problem, but if this blockage problem is not handled well, it will easily cause equipment damage and affect the efficiency of use. Therefore, everyone should pay special attention to it. In fact, if you grasp the following points, you can easily solve the problem.(1) If the hardened sediment in the vortex shell of the horizontal slurry pump is silted, measures can be taken to remove the silt.(2) If the shaft and the material adding box have different axis centers, the main reason is that the processing error is large and the installation is incorrect.Pay attention to check whether the installation is correct after installation.If the sealed water ring is seriously worn, a new water ring needs to be replaced.If the sealed clean water pipe is blocked, the sealed water cannot enter the middle of the pack, causing the pack to wear quickly and lead to material leakage.The blocked water pipes should be unblocked to keep the sealed water clean.(3) If the impeller or the inlet and outlet pipes are blocked, you can clean the impeller or pipeline.If the impeller is worn seriously, replacement should be taken.If the filler outlet leaks, the filler should be tightened.The conveying height is too high, and the resistance loss in the pipe is too large, which reduces the conveying height or reduces the resistance.What are the reasons for noise during operation of the submersible slurry pump? Let’s take a brief look at it: 1. The medium density is uneven, and the medium density is uneven. The pump will vibrate when it starts.2. The vertical slurry pump has cavitation, causing the pump impeller to be uneven.The installation height should be reduced, the water outlet valve should be adjusted to reduce the import resistance.3. If the pump bearing has a large clearance, too large the bearing clearance will cause the pump to vibrate greatly.4. The installation of the vertical slurry pump is not level, and the level of the pump body should be checked during installation and operation.5. If the intake of the suction pipe is uneven, the feeding condition of the pump should be improved to enhance the average stability of the intake.The above is the reason for noise during the operation of the submersible slurry pump. Everyone is welcome to come and consult.
