Brief Introduction to Common Faults and Solutions of Slurry Pumps in Hualian Mining Pumps

[Pump Network in Asia] Shijiazhuang Hualian Mining Pump Co., Ltd. (hereinafter referred to as Hualian Mining Pump) is a research, design, manufacture in one of the slurry pumps, sewage pumps, water pumps, chemical pumps and other large integrated pump Industry companies, is the domestic slurry pump industry's leading enterprises. Today, Hualian mining pump and everyone to interpret the slurry pump. Hualian mining pump slurry pump on the common failures and solutions Slurry pump from the working principle is a centrifugal pump, conceptually refers to by means of centrifugal force (pump impeller rotation) of the role of solid and liquid mixed media A machine that adds energy, a device that converts electrical energy into kinetic and potential energy of the medium. Nowadays, the applications of slurry pumps are becoming more and more widely used in production and daily life. Therefore, it is especially important to know their common faults and solutions. However, many consumers are often overwhelmed, Hualian Mining Pump inventory slurry pump in this common failures and solutions for your reference. Slurry pump common faults and solutions (1) the pump does not turn solution: volute solidified hard sediment blockage, can take measures to remove the blockage. (2) Insufficient pump flow solution: If the impeller or the inlet and outlet pipes are obstructed, the impeller or pipe may be cleaned. Such as impeller wear serious, should be replaced. Such as packing leakage, should be pressed packing. (3) pump vibration, noisy Solution: ① media density is not uniform. When the pump is just started, the vibration of the pump will disappear. This condition does not need to be dealt with. Just before driving, pay attention to blowing the medium with high-pressure air; ② The installation of the pump Not level. Check the level of the pump body during installation and operation. ③ cavitation, so that the impeller pump imbalance. Should reduce the installation height, adjust the outlet valve, reduce the import resistance. ④ suction tube inlet uneven. Should improve the pump feed conditions, and strengthen the uniform intake stability. ⑤ pump bearing clearance. Bearing clearance over the General Assembly led to large pump vibration, running in the daily operation of the pump should always observe the situation and found that the pump shaft and motor shaft or bearing damage is not timely treatment. (4) bearing fever solution: ① not open the cold water or cooling water tank is blocked, you should open the cooling water function or clear the cooling waterway. ② equipment lubrication is not good. Adjust the amount of lubricant according to the instructions. ③ lubricant is not clean, oil impurities. Should clean the bearings, for lubricating oil. ④ thrust bearing wrong direction. For the import pressure, adjust the thrust bearing direction. ⑤ bearing air outlet blockage, leading to the bearing box body of heat can not be discharged, so that equipment temperature. Air outlet should be cleaned. (5) bearing short life solution: ① motor shaft and pump shaft asymmetry or not parallel. The motor shaft or pump shaft should be adjusted to replace the shaft if it deforms or bends. ② bearing assembly is unreasonable. Replace the bearing and shaft, or replace the bearing. ③ pump friction or impeller out of balance. Should eliminate friction or replace the new impeller. ④ lubrication is not good. Excessive too little impurities will lead to bearing life is short, the bearings should be removed before use. The above is the Hualian mining pump technicians on the slurry pump to make common solutions to problems, I hope for everyone to help. Hualian Mining Pump adhere to the pump production, mechanical design, machinery manufacturing, precision machining, product casting as the main business direction. We warmly welcome all customers here guidance, letter calls business negotiations in order to work together and seek common development and create a win-win situation.
