How the excavator works

The chemical energy of the diesel oil is converted into mechanical energy by the diesel engine, the mechanical energy is converted into hydraulic energy by the hydraulic plunger pump, and the hydraulic energy is distributed to each actuator (hydraulic cylinder, rotary motor + reducer, walking motor + reducer) through the hydraulic system, and then the hydraulic energy is converted into mechanical energy by each actuator. Realize the movement of the working device, the rotation of the rotating platform and the walking movement of the whole machine.

1. Walking power transmission route: diesel engine - coupling - hydraulic pump (mechanical energy into hydraulic energy) - distribution valve - central rotary joint - walking motor (hydraulic energy into mechanical energy) - reducer box - driving wheel - rail chain track - to achieve walking.

2. Rotary transmission route: diesel engine - coupling - hydraulic pump (mechanical energy into hydraulic energy) - distribution valve - rotary motor (hydraulic energy into mechanical energy) - gearbox - rotary support - to achieve rotary.

3. Transmission route of boom movement: diesel engine - coupling - hydraulic pump (mechanical energy into hydraulic energy) - distribution valve - boom cylinder (hydraulic energy into mechanical energy) - to achieve boom movement.

4. Bucket rod movement transmission route: diesel engine - coupling - hydraulic pump (mechanical energy into hydraulic energy) - distribution valve - bucket rod cylinder (hydraulic energy into mechanical energy) - to achieve bucket rod movement.

Bucket movement transmission route: diesel engine - coupling - hydraulic pump (mechanical energy into hydraulic energy) - distribution valve - bucket cylinder (hydraulic energy into mechanical energy) - to achieve bucket movement.
