Product introduction：
QYB-0.45/70 pneumatic oil pump adopts a combination of cycloid pump and plunger pump to supply oil to provide high-pressure oil power to the jack.
Technical features：
Easy to operate
It is easy to operate, can be started and braked instantaneously, can be started with load, and can maintain a stable state after starting. The reversing valve handle can easily control the direction of the oil circuit.
Small and light
The air motor directly drives the cycloid rotor pump and the plunger pump on the same shaft to work, and the high-pressure oil enters the actuator through the manual reversing valve.
High working efficiency
The large displacement cycloid pump and plunger pump simultaneously supply oil to the implement.
Easy to transport and install
It is small in size and has a solid wheel set, which can easily reach the designated position for work in the complex environment of the mine.The pump can be separated from the machine and installed directly on platforms such as drilling rigs, reducing safety hazards.
