Cause Analysis of Gear Pump Motor Overheating

Gear pump for conveying solid particles and fiber-free, non-corrosive, the temperature is not higher than 80 ℃, the viscosity of 5 × 10-6 ~ 1.5 × 10-3m2 / s (5-1500cSt) of lubricating oil or similar properties Oil and other liquids as well as for hydraulic rotary system. Petroleum. Chemical. Metallurgy. Mining. Power plants and other industries the transfer of oil media. Turbocharged. Fuel injection, and large machinery and equipment in the thin oil circulation, in various types of machinery and equipment Can be used in the lubrication pump. Motor overheating is the gear pump often appear in the course of the work of the problem, the specific analysis and testing are as follows: 1. The use of the range (flow. Head) More than gear pump design? 2. The proportion of the medium exceeds the gear pump configuration motor? Configure the appropriate gear pump motor 3. Packing gland pressure is too tight or mechanical seal spring too tight? Re-adjust the gland or mechanical seal spring compression 4. Pump Assembly quality is poor, there is friction or motor and pump shaft is not the heart? Check the assembly quality, eliminate assembly failure? Can be for the above conditions, one by one to do analysis to find out the real cause of motor overheating, in accordance with the corresponding fault, maintenance treatment.
