Novel high-pressure water spraying hydraulic driving system

Abstract

Disclosed is a novel high-pressure water spraying hydraulic driving system that comprises a cleaning vehicle body, wherein the cleaning vehicle body comprises a vehicle frame, a cab arranged on the vehicle frame and a stainless steel water tank used for containing water; the water tank comprises a top part, a bottom part and two side parts; the outer wall of the bottom part of the water tank is connected with a high-pressure water spraying hydraulic driving system, and the high-pressure water spraying hydraulic driving system comprises a water pipe 1, a water filter, a water pump water level monitor, a water cooling exchanger, a water pipe 2, a water pump, a water pump hydraulic driving motor, a control valve and a hydraulic pump which are mutually connected. The output of the water pump is changed through the control valve, the controllable degree is high, and the energy-saving degree is high; a water source is utilized to the maximum extent, and the utilization rate of the water source is increased to the maximum extent by allowing water to enter the water cooling exchanger before entering the water pump; by arranging an exhaust gate valve, the water pump is effectively protected, the service life is prolonged, certain air suction force of the water pump is kept, and the water pump can operate more stably.

Description

technical field [0001] The invention relates to a novel high-pressure water spray hydraulic driving system. Background technique [0002] At present, with the continuous development of China's urbanization and the environmental requirements of energy conservation and emission reduction, the country's demand for road cleaning and sweeping vehicles is increasing. In the prior art, conventional cleaning vehicles generally have a high-pressure cleaning function. The water hydraulic drive system is the guarantee for high pressure cleaning. [0003] However, most of the current high-pressure water jet driving systems have the main problems of high energy loss and low efficiency, and cannot realize the function of automatically adjusting the working state according to changes in working conditions. High-efficiency, energy-saving and high-efficiency, a high-pressure water spray hydraulic drive system that can automatically adjust the driving power according to changes in working co...
