Excavator power system

1. The power transmission route of excavator is as follows

1) Traveling power transmission route: diesel engine I - coupling I - hydraulic pump (mechanical energy is converted into hydraulic energy) - distribution valve - central rotary joint - traveling motor (hydraulic energy is converted into mechanical energy) - gearbox I - driving wheel - rail chain track - to realize traveling

2) Transmission route of slewing motion: diesel engine I - coupling - hydraulic pump (mechanical energy is converted into hydraulic energy) - distribution valve - slewing motor (hydraulic energy is converted into mechanical energy) - reduction gearbox - slewing bearing - slewing

3) Boom movement transmission route: diesel engine -- coupling -- hydraulic pump (mechanical energy is converted into hydraulic energy) -- distribution valve -- boom cylinder (hydraulic energy is converted into mechanical energy) -- to realize boom movement

4) Transmission route of stick movement: diesel engine - coupling - hydraulic pump (mechanical energy is converted into hydraulic energy) - distribution valve - stick cylinder (hydraulic energy is converted into mechanical energy) - to realize stick movement

5) Bucket movement transmission route: diesel engine -- coupling -- hydraulic pump (mechanical energy is converted into hydraulic energy) -- distribution valve -- bucket cylinder (hydraulic energy is converted into mechanical energy) -- to realize bucket movement
