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.

泵內(nèi)全部零件的潤滑均在泵工作時(shí)利用輸出介質(zhì)而自動(dòng)達(dá)到。產(chǎn)品廣泛適用于各類切削機(jī)床、鍛壓、鑄造、數(shù)控機(jī)械、紡織機(jī)械、注塑機(jī)械、木工機(jī)械、橡膠機(jī)械、食品機(jī)械、印刷機(jī)械、冶金機(jī)械等行業(yè)。

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.

泵內(nèi)有設(shè)計(jì)合理的泄油和回油槽，是齒輪在工作中承受的扭矩力更小，因此軸承負(fù)荷小，磨損小，泵效率高。泵設(shè)有閥作為超載保護(hù)，閥的全回流壓力為泵額定排除壓力的1.5倍，也可在允許排出壓力范圍內(nèi)根據(jù)實(shí)際需要另外調(diào)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.

但注意本閥不能作減壓閥的長期工作，需要時(shí)可在管路上另行安裝。

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.

從主軸外伸端向泵看，為順時(shí)針旋轉(zhuǎn)。大流量齒輪油泵，齒輪泵，缷油泵，輸油泵，原油泵，船用齒輪泵等。

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.
