Abstract

The invention discloses a power control method, a control system and a garbage truck of a pure electric compression type garbage truck. The power control method includes: obtaining the pressure value in the oil cylinder or at the outlet of the gear pump; according to the obtained pressure value, according to the preset Mathematical relationship model R=n*P*V / Real-time adjustment of the motor speed to control the output flow of the gear pump, where n is the motor speed, P is the pressure value, and R is the preset power value according to the working conditions. Is the variable; V is the displacement of the gear pump; η is the efficiency. The present invention controls the motor speed according to the pressure value obtained in the oil cylinder or at the outlet of the gear pump and according to the preset mathematical relationship model during the cyclic compression action. Fine control reduces the overflow flow of the gear pump to achieve the purpose of improving efficiency and saving energy.

Description

technical field [0001] The invention relates to the technical field of garbage compression, in particular to a power control method, a control system and a garbage truck of a pure electric compression garbage truck. Background technique [0002] With the acceleration of urbanization in our country, the proportion of compressed garbage trucks in sanitation vehicles is increasing, and its importance is also increasing. As people across the country have higher and higher requirements for the environment, the demand for pure electric compression garbage trucks is also on the agenda. The pure electric compression garbage truck has the advantages of zero emission and low noise. [0003] The pure electric compression garbage truck is the same as the fuel chassis compression garbage truck. The operation of the main body parts is completed by the electric motor or the engine driven hydraulic system. The transmission connection of the functional layout of the existing pure electric ...
