What Problems Will Be Caused By Improper Use Of The Slurry Pump?

At present, 80% of slurry pumps are widely used in factory selection to transport slurry. Whether the flow rate, rotation speed and other parameters of the slurry pump are reasonable directly affects the life of the slurry.Choosing the appropriate working parameters can not only give full play to the performance of the slurry pump, but also improve the service life. If the choice is improper, the slurry pump will not work properly, and may even cause the factory to be selected and production will be suspended.In order to fully utilize the performance of the slurry pump, it is necessary to fully understand the relationship between the slurry flow rate, rotation speed, etc. and the life of the slurry pump in actual work.Due to the flow of the ore slurry in the slurry pump, the ore slurry will cause impact and wear on the inner lining of the pump body. Obviously, with the same slurry flow rate, the slower the slurry flow rate, the lighter the wear of the pump body, and the longer the service life of the slurry pump.Therefore, the design flow rate should be as small as possible while ensuring the efficiency of the slurry pump.Furthermore, the lower the pump speed, the lower the relative speed of the impeller and the slurry will be, and the slower the wear speed of the impeller will be.In addition, at the same flow rate, the larger the diameter of the impeller, the lower the rotation speed, the fewer ore particles per unit area, and the wear of the impeller is lighter.Therefore, the correct choice should be a large pump with low speed, which can extend its service life and reduce costs due to its light wear.In addition to flow rate and speed, the head also has a certain impact on the life of the pump. The actual head of the pump must be controlled within the withstandable range. Otherwise, too high head will lead to excessive flow of the pump. On the one hand, it will cause evacuation and damage to the pump. On the other hand, too large flow will increase wear and reduce service life.Slurry pumps are commonly used in ore dressing processes and are mainly used for ore slurry transportation.Improper use of slurry pumps may affect the normal operation of slurry pumps and affect their production capacity.What problems can easily cause improper use of slurry pumps, and how to solve them to make the slurry pump run normally?1. The long-term use of the slurry pump causes scaling on the surface of the cooler pipe wall, resulting in poor heat transfer; the cooling water volume is small or no cooling water is added.Therefore, it is necessary to check whether the bearing cooling water pressure and flow rate are suitable. Generally, the cooling water pressure of the slurry pump is 0.05~0.2MPa, and the cooling water flow rate is 1~3m3/h. Change the scaling cooler in time, turn on the cooling water before the pump starts to adjust the pressure to the specified value, and check the bearing temperature rise (35℃) regularly. The high temperature must not be greater than 75℃.2. During the use of the slurry pump, the seal failed due to packing wear, and the slurry leaked along the shaft seal. The slurry instantly filled the semicircular positioning hole curved surface of the bracket and the rear pump shell. The slurry discharged from the discharge port could not be sealed into the oil pool through the water barrier plate, causing bearing damage.During daily maintenance, attention should be paid to regularly detecting the leakage of shaft seal water. When the leakage amount increases, the bolts of the filler gland should be adjusted, and the packing and failed O-rings should be replaced in time to prevent leakage slurry from leaking from the waterproofing plate sealing into the bracket oil tank along the shaft.3. The lubricant oil is not clean, resulting in problems such as bearing friction, wear, heating, vibration, etc. You can lubricate various parts of the bearing to reduce friction and wear. The quality of the lubricant should be checked regularly to allow dust or oil to age and deteriorate.The lubricating oil should be adjusted strictly in accordance with the pump instruction manual. It should not be too much or too little. If there is too much oil, most of the friction heat inside the bearing cannot be taken away, which will not play an effective role in heat dissipation, and will also increase the temperature rise of the bearing; if there is less oil, it will cause the bearing oil film to rupture and dry friction, burn the bearing.These small problems with slurry pumps will have a great impact over time and should be checked in time and repaired in time to ensure the normal use of slurry pumps.
