Key points for quality inspection of high viscosity gear pump?

The high quality and high quality of the high viscosity gear pump mainly depends on the machining accuracy of the internal parts of the gear pump and the gear pump. Let us Yiyang pump technicians analyze the key points for the quality inspection of the high viscosity gear pump. Yiyang pump is a high viscosity gear pump with very reliable quality. It is well-known in the industry and has a good reputation

First, according to the different characteristics of the transmission medium, reasonably select the mechanical sealing materials and sealing forms of gear pump and gear oil pump.

Second, reasonably select the materials of gear pump and gear oil pump, and reasonably do the quenching, tempering and heat treatment of various parts according to the different characteristics of each different material.

Third, all parts of the gear pump and gear oil pump must be processed according to the process drawings and technical standards. Every small process can not be missing, especially the oil return hole, pressure relief hole, balance hole, etc. in the gear pump.

Fourth, the three body unity of the gear pump, the pump body of the gear oil pump and the front and rear pump covers, and the coaxiality of the bearing positioning holes of the pump covers on both sides must be accurate. Otherwise, a series of problems such as grinding the eccentric shaft sleeve for a long time and damaging the seal of the gear pump will be caused by the non concentric positioning of the bearings.
