The invention discloses a hydraulic oil cooling device of a hydraulic machine. A filter is arranged between an oil return pipe and an oil inlet pipe, a plurality of heat exchanging oil pipes are mounted in a cooling water tank in parallel, the left ends of the heat exchanging oil pipes are connected with the oil inlet pipe after communicating with one another through vertical pipelines, the rightends of the heat exchanging oil pipes are connected with an oil outlet pipe after communicating with one another through vertical pipelines, the end, extending out of the cooling water tank, of the oil outlet pipe is connected with a three-way pipe, one port of the three-way pipe is connected with an oil station through a pipeline, and another port of the three-way pipe is connected with the oil inlet pipe through a backflow pipe. A temperature sensor is arranged on the inner wall of the oil outlet pipe, an electromagnetic valve is arranged on the pipeline between the tree-way pipe and the oilstation, the temperature sensor is electrically connected with the electromagnetic valve through a micro controller, a backflow pump is arranged on the backflow pipe, and the temperature sensor is electrically connected with a switch of the backflow pump through an oil pump switch controller. The hydraulic oil cooling device is simple in structure, the staying time of cold water in the cooling water tank is prolonged, the contact areas of the heat exchanging oil pipes and the cold water are enlarged, and the cooling efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of hydraulic machinery equipment, and relates to a hydraulic oil cooling device of a hydraulic machine. Background technique [0002] The hydraulic oil of the hydraulic machine is easily heated during work, which makes the hydraulic oil thinner, lower in viscosity, and lower in density, which greatly affects its hydraulic pressure, resulting in unstable operation of the hydraulic machine and shortening the working life of the hydraulic machine; therefore, the hydraulic oil needs to be checked. cooling, but the mechanism of the existing hydraulic oil cooling device is complicated, the residence time of cold water in the cooling water tank is short, the heat exchange is insufficient, and the cooling efficiency is low. Contents of the invention [0003] In order to achieve the above object, the present invention provides a hydraulic oil cooling device for a hydraulic machine, which has a simple structure, pro...
