Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic systems of reclaimers, in particular to a hydraulic component of a mobile reclaimer. Background Art

[0002] Hydraulic transmission uses liquid as the working medium and utilizes the pressure energy of the liquid to transmit power. A complete hydraulic system consists of five parts, namely, energy device, actuator, control and adjustment device, auxiliary device, and liquid medium. Hydraulics are widely used in industry and civil industries due to its characteristics of large power transmission, easy transmission and configuration. The function of the actuator (hydraulic cylinder and hydraulic motor) of the hydraulic system is to convert the pressure energy of the liquid into mechanical energy, thereby obtaining the required linear reciprocating motion or rotary motion. The function of the energy device (hydraulic pump) of the hydraulic system is to convert the mechanical energy of the prime mover into the pressure energy of the liquid. The existing mobile material-reclaiming vehicle uses an electric motor to provide kinetic energy when advancing the material-reclaiming, which is easy to overload and burn out. If the hydraulic components are used for transmission, the temperature will be too high for a long time, the control system is prone to high temperature jamming, and the service life of the hydraulic components is short.
