DC motor hydraulic power unit

24V DC motorHydraulic Power UnitRated power: 2.2 (kW), rated voltage: 24 (V), rated current: multiple (A), rated speed: 2500 (rpm), rated torque: multiple (NM), external dimensions: multiple (mm), product certification: CCC, applicable scope: power unit, efficiency: 98 (%). Our company specializes in the production, processing, distribution, and wholesale of hydraulic products, which are mainly used in the vehicle modification and manufacturing industry. The products include a complete set of hydraulic systems for flying wing cars, stage cars, car legs, and dump truck covers.

Various types of motors and the selected motor for this design are DC brushless motors. The price of DC brushless motors is relatively similar, and the sealing structure is also relatively simplified. The motor housing is equipped with a pressure compensator, and the motor is filled with a certain amount of compensating oil. Balance the pressure inside and outside the motor housing through a pressure compensator. The stator casing, front end cover, and rear end cover of the electric motor form a sealed shell, which belongs to the static sealing problem.

The stator casing, front end cover, and rear end cover of the electric motor form a sealed shell, which belongs to the static sealing problem.

Therefore, O-rings are used for sealing at the front and rear covers. The combination sealing ring adopts an organic combination of polytetrafluoroethylene inner ring and O-ring outer ring, making the seal at the shaft extension a dynamic seal. The maximum power of the electric motor can be determined based on the rated speed of the hydraulic pump at full load. Given that the displacement of the hydraulic pump is V=35mL/r and the pressure of the pump is p=25MPa, the selected pump speed is n=1500r/min, and the total efficiency of the pump is taken as η=0.98
