Abstract
Gear pump is to use a pair of mutually meshing gears, the original motivation for the output of mechanical energy to hydraulic energy conversion device, As in the hydraulic system to provide a flow of hydraulic pressure energy. Gear pump with high efficiency, high-performance, pressure to engage, engage in reliability and easy installation and maintenance. Papers gear pump briefed the significance of technological development and industry in our country the status of gear pumps. Analysis of the gear oil pump failure in the maintenance of the hot issues during the design process and its improvement. Side the body design of the floating pump to improve the life of gear pumps.To improve the processing quality pump to study the process of the axis line and the preparation of their card processing. In the use of gear pumps for the process of sealing, channeling oil failure Its solution, and finally the maintenance of pumps and other gear suggestions.
Key words：Gear Oil Pump Floating side Processing Technology Maintenance
