The gear pump of automatic oiling machine series mainly consists of gear, shaft, pump body, safety valve and shaft end seal. The gear has high hardness and strength after heat treatment, and is installed in the replaceable shaft sleeve together with the shaft for operation.

泵内全部零件的润滑均在泵工作时利用输出介质而自动达到。产品广泛适用于各类切削机床、锻压、铸造、数控机械、纺织机械、注塑机械、木工机械、橡胶机械、食品机械、印刷机械、冶金机械等行业。

The lubrication of all parts in the pump is achieved automatically by using the output medium when the pump is working. The products are widely used in all kinds of cutting machine tools, forging, casting, CNC machinery, textile machinery, injection molding machinery, woodworking machinery, rubber machinery, food machinery, printing machinery, metallurgical machinery and other industries.

泵内有设计合理的泄油和回油槽，是齿轮在工作中承受的扭矩力更小，因此轴承负荷小，磨损小，泵效率高。泵设有阀作为超载保护，阀的全回流压力为泵额定排除压力的1.5倍，也可在允许排出压力范围内根据实际需要另外调整。

There are reasonable oil drain and return grooves in the pump, so the torque force of the gear is the least, so the bearing load is small, the wear is small, and the pump efficiency is high. The pump is equipped with a safety valve for overload protection. The total return pressure of the safety valve is 1.5 times of the rated discharge pressure of the pump. It can also be adjusted within the allowable discharge pressure range according to the actual needs.

但注意本阀不能作减压阀的长期工作，需要时可在管路上另行安装。

However, it should be noted that the safety valve can not be used for long-term work of the pressure reducing valve, and can be installed separately on the pipeline if necessary.

从主轴外伸端向泵看，为顺时针旋转。大流量齿轮油泵，齿轮泵，缷油泵，输油泵，原油泵，船用齿轮泵等。

From the extended end of the main shaft to the pump, it is clockwise rotation. Large flow gear pump, gear pump, unloading oil pump, oil pump, crude oil pump, marine gear pump, etc.
