Embodiment 1

[0047] This embodiment provides an oil temperature control method, such as figure 1 As shown, the methods include:

[0048] S110, acquiring a first current temperature of the oil, and judging whether the first current temperature satisfies a preset temperature setting value;

[0049] When the hydraulic system is running, the first current temperature of the oil is obtained by using the temperature monitoring device, and it is judged whether the first current temperature satisfies a preset temperature setting value. Here, when the oil temperature is too high or too low, it will cause the failure of the hydraulic equipment, so see figure 2, the temperature adjustment interval in this embodiment includes two: low temperature adjustment interval A and high temperature adjustment interval B; then the temperature setting value includes: the first temperature setting value and the second temperature setting value, the first temperature setting value The second temperature setting ...

Embodiment 2

[0082] This implementation provides an oil temperature control device, such as image 3 As shown, the device includes: a judging unit 31 and a generating unit 32; wherein,

[0083] The judging unit 31 is configured to acquire a first current temperature of the oil, and judge whether the first current temperature satisfies a preset temperature setting value; acquire a second current temperature of the oil, and judge the second current temperature Whether the preset temperature adjustment end point value is met;

[0084] A generating unit 32, configured to generate a first trigger signal if it is determined that the first current temperature satisfies the temperature setting value; the first trigger signal is used to first control the circulation pump to be turned on, and then control the temperature regulator to be turned on; When it is determined that the second adjustment temperature satisfies the temperature adjustment end value, a second trigger signal is generated; the se...

Abstract

The invention provides an oil temperature control method and device. The method comprises the steps that whether the first current temperature of oil meets a preset temperature set value or not is judged; if it is determined that the first current temperature meets the temperature set value, a first trigger signal is generated; the first trigger signal is used for firstly controlling a circulatingpump to be started and then controlling a temperature regulator to be started; whether the second current temperature of the oil meets a preset temperature regulation end point value or not is judged, and a second trigger signal is generated when it is determined that the second regulation temperature meets the temperature regulation end point value; the second trigger signal is used for firstlycontrolling the temperature regulator to be stopped and then controlling the circulating pump to be stopped; in this way, the oil temperature can be intelligently monitored and regulated, and the regulation efficiency is ensured; the temperature of oil is controlled through circular heating or circular cooling so that the temperature of the oil can be more uniform; and the oil is periodically filtered on the basis of the preset period, abrasion to cleaning equipment is reduced, the fault rate of the cleaning equipment is decreased, and the energy conservation and efficiency improvement are achieved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic automatic control, in particular to an oil temperature control method and device. Background technique [0002] With the continuous improvement of the degree of automation and the popularization of artificial intelligence, cost reduction and efficiency increase have increasingly attracted people's attention. In the hydraulic system, in order to ensure the normal operation of the hydraulic system, the hydraulic or lubricating performance of the oil, the oil temperature index, and the cleanliness index must be met. [0003] In the prior art, in order to ensure that the oil temperature meets the preset requirements, most hydraulic or lubrication systems manually control the start and stop of heaters and coolers according to seasonal temperature changes. The temperature adjustment process is cumbersome and the adjustment efficiency is low; The cleanliness of the oil meets the requirements, and most...
