Energy-saving type pure electric kitchen garbage truck hydraulic control system

Abstract

The invention discloses an energy-saving type pure electric kitchen garbage truck hydraulic control system. The energy-saving type pure electric kitchen garbage truck hydraulic control system comprises a power unit, an energy accumulator unit and an unloading unit, an oil inlet of the unloading unit is connected with a pipeline between the power unit and a one-way valve through a pipeline, the oiloutlet of the unloading unit is connected with an oil tank through a pipeline, the oil inlet of a hydraulic control one-way valve is connected with the pipeline between the one-way valve and a multi-way valve through the pipeline, the oil outlet of the hydraulic control the one-way valve is connected with the energy accumulator through a pipeline, the oil inlet of the two-position two-way electromagnetic reversing valve is connected with a pipeline between the hydraulic control one-way valve and the energy accumulator through a pipeline, an oil outlet of a two-position two-way electromagneticreversing valve is connected with a control port of the hydraulic control one-way valve through a pipeline. When the kitchen garbage truck works, the surplus flow in a hydraulic system is stored by the energy accumulator, and the overflow rate of the hydraulic system is reduced; when an executing mechanism only needs small flow, the energy maintenance system of the energy accumulator is releasedto operate, the working time of a motor pump is shortened, and therefore the energy conservation of the hydraulic system is realized.

Description

technical field [0001] The application relates to the technical field of auto parts, in particular to an energy-saving pure electric kitchen garbage truck hydraulic control system. Background technique [0002] With the rapid development of my country's catering industry, there are nearly 3.5 million hotels and restaurants in my country, and the amount of kitchen waste generated every day is astonishing. In order to realize the collection and transfer of food waste, the supporting food waste trucks have also been developed rapidly. Pure electric kitchen garbage trucks have the advantages of low noise, no emission pollution, and stable operation, and have gradually become the main equipment for urban kitchen garbage collection and transportation. At present, extending the operating time and increasing the cruising range are the key research directions of pure electric kitchen garbage trucks, and energy saving and consumption reduction have become the key areas of technical r...

Problems solved by technology

During the working process, the flow rate of hydraulic oil required by each actuator is quite different. When an actuator with a small flow rate is used, a large amount of hydraulic oil will overflow through the relief valve, causing the energy generated by the oil pump to be converted into system heat. Increase the heat dissipation burden of the hydraulic system, and at the same time increase the energy consumption of the vehicle, affecting the mileage of the vehicle
