Oil temperature control device of paver hydraulic system

Abstract

The invention discloses an oil temperature control device of a paver hydraulic system. The oil temperature control device comprises an oil tank, a hydraulic oil radiator, a fan, a motor, a temperature control valve, a returned oil collecting pipe, a first pipeline, a second pipeline, a third pipeline and a fourth pipeline, wherein an output shaft of the motor is connected with the fan; one end of the first pipeline is connected with the returned oil collecting pipe, and the other end of the first pipeline is connected with an oil inlet P of the temperature control valve; one end of the second pipeline is connected with an oil return port T of the temperature control valve, and the other end of the second pipeline is communicated with the oil tank; one end of the first pipeline is connected with a working oil port A of the temperature control valve, and the other end of the third pipeline is connected with an oil inlet of the hydraulic oil radiator; and one end of the fourth pipeline is connected with an oil outlet of the hydraulic oil radiator, and the other end of the fourth pipeline is communicated with the oil tank. The oil temperature control device realizes automatic constant-temperature control of oil temperature of the paver hydraulic system, ensures hydraulic elements to locate in excellent lubricating state through constant temperature of hydraulic oil, and effectively guarantees the service life of the hydraulic elements and the reliability of the hydraulic system.

Description

technical field [0001] The invention relates to an oil temperature control device, in particular to a paver hydraulic system oil temperature control device. Background technique [0002] The existing paver hydraulic system generally controls the oil temperature by direct forced cooling regardless of the oil temperature. Hydraulic components only work in high-efficiency conditions when the oil temperature is within a certain range. In order to solve this problem, a technology that uses a variable displacement pump to drive a hydraulic motor to drive a fan has emerged. However, this technology has high cost, complicated control and low efficiency. How to develop an oil temperature control device with simple control, low technical cost and high efficiency is a technical problem to be solved urgently by those in the relevant technical field. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art ...
