Gear pump is mainly used in the oil, chemical, metallurgy, mining, power plants and other industries in the transfer of oil media, booster, fuel injection, and large oil and gas recycling machinery and equipment, in all types of machinery and equipment can be done in the lubrication pump use. The overheating of the motor is a common problem in the work of the gear pump. The specific analysis and testing are as follows: â… . The scope of use (flow, lift) exceeds the design requirements of the gear pump According to the series of spectrum select the appropriate motor â…¡, the proportion of the medium exceeds the gear pump configuration motor Configure the appropriate gear motor oil pump â…¢, packing gland pressure is too tight or mechanical seal spring is too tight adjust the gland or mechanical seal spring compression â…£, the pump assembly quality is poor, friction or motor and the pump Axis do not check the assembly of different quality, troubleshooting can eliminate assembly For the above conditions, one by one to do the analysis to find out the real cause of motor overheating, in accordance with the corresponding fault, maintenance treatment.
