Detailed Description

The present application is described in further detail below with reference to the attached drawings.

According to the existing lubricating system with double temperature control, another branch is arranged beside a temperature control oil way, when a temperature control device in the temperature control oil way breaks down, oil is supplied through the branch, and the condition that oil is lack between mechanical equipment parts due to the failure of the lubricating system is reduced.

From the perspective of a user, when the system is used in a bearing test system, after the branch is switched, the temperature of lubricating oil flowing into parts of mechanical equipment can be suddenly changed due to the failure of the temperature control valve group, and an experimental result is influenced.

Specifically, two input ends of the water mixing valve 31 are respectively connected with the temperature rising device 41 and the cooling device 42, so that high-temperature oil and low-temperature oil are mixed, and the mixed oil enters a testing machine needing lubrication after reaching a required temperature. The temperature is fed back by the first temperature sensor 51 and the second temperature sensor 52, and the water mixing valve 31 is adjusted.

Thus, when the water mixing valve 31 is in a fault, the second temperature sensor 52 detects that the oil temperature is abnormal, feeds the oil temperature back to the control module, closes the electromagnetic valve 53 where the fault water mixing valve 31 is located, opens the other electromagnetic valve 53, and supplies oil through the water mixing valve 31 where the electromagnetic valve 53 is located, so that the fluctuation of the oil temperature is reduced.

In some possible embodiments, the first temperature sensor 51 and the second temperature sensor 52 are both temperature sensors, the mixing valve 31 is an adjustable thermostatic mixing valve, and the output end of the mixing valve 31 is provided with a valve 311.

As a specific embodiment of the dual temperature controlled lubrication system provided by the application, a third temperature sensor 54 is mounted at the output end of the water mixing valve 31, and the third temperature sensor 54 is electrically connected to the control module.

Generally, by installing the third temperature sensor 54, the two parallel water mixing valves 31 are used for mixing oil and supplying oil at the same time in a normal state, when the second temperature sensor 52 detects that the oil temperature is abnormal, the third temperature sensor 54 feeds back the temperature to determine the abnormal water mixing valve 31 and close the corresponding oil path, so that the influence of temperature change caused by oil path switching on an experiment is reduced.

Furthermore, the input ends of the mixing valves 31 are all provided with proportional valves 6, and the proportional valves 6 are electrically connected to the control module.

It should be understood that the communication pipeline 43 is connected with the testing machine, and oil is supplied independently when the testing machine needs a high-temperature test or a low-temperature test, so that the energy consumption of the other oil way is reduced.

Further, the connection point of the communication pipe 43 and the temperature increasing device 41 is located on the side of the first temperature sensor 51 away from the temperature increasing device 41.

It should be understood that the temperature of the communication pipeline 43 is detected through the first temperature sensor 51, so that the oil temperature in the tester is more accurate.
