如何延长齿轮油泵寿命（How to prolong the life of gear oil pump） How to prolong the service life of high viscosity gear pumps? The conveying medium is not only an intermediary of energy transfer, but also a lubricant, seal and heat transfer medium. The transmission of high viscosity liquid gear pump should be at lower power consumption, less leakage, greater pressure, the output of the most traffic. Liquid viscosity reflects the ease of flow of medium, too high viscosity will increase the internal friction resistance. Lower output power. Waste energy and produce excessive system temperature. In determining the medium to be conveyed, the product specification should be strictly followed, as far as possible the use of fluid media recommended by the manufacturer, and pay attention to the system operating temperature range. The viscosity index of the conveying medium should be higher when it is desired to be used in a wide range of temperatures. When the viscosity of the liquid is higher, or when the system works in a cold environment. It is necessary to ensure that the conveying medium flows smoothly. Many oil composition containing wax, they very easily at low temperatures, crystallization, freezing point transmission medium should be lower than the expected minimum operating temperature. In addition, the medium to be transported must be compatible with the sealing, gaskets, hoses and other rubber materials in the system. If the two are not compatible, then the transport medium must be re determined. 1. noise problems Rapid changes in fluid velocity, flow, and pressure in a fluid delivery system. Bubble rupture and alternating load are common causes of noise. Gear pumps with high viscosity liquid are the main sources of noise. ?? Reasonable determination of the gear pump speed, gear and shaft rotation to avoid the meshing resonance frequency, can prevent noise. Because the resonance frequency is easy to occur when the meshing frequency is close to the natural frequency of the gea
