Talking about the hydraulic drive motor of imported excavator accessories

Anyone who knows about excavators knows that the walking and work of excavators are all done by hydraulic pressure. Some people may ask, why tanks can walk so fast while excavators can only walk on tracks. Gradually leave?

This is the difference in the power output system. The tank is mechanically rigidly connected to travel. Like the driving method of a car, the relationship between power and speed is harmonious through the gearbox switching gear set, while the excavator is driven by hydraulic pressure. It does not mean that hydraulic drive is necessarily slower than mechanical transmission, but it is determined by job requirements. The so-called demand determines production. When the excavator moves, it does not require high walking speed, but requires a large driving force, so the excavator is Plunger-type drive motor, the major feature of this hydraulic drive motor is the output of low speed and high torque.

Liugong excavator accessories hydraulic drive motors are generally divided into gear type, vane type, plunger type and other forms. Because the excavator uses the plunger type, the gear type and the vane type will not be introduced today. I hope that in the future Have the opportunity to discuss with everyone again.
