Preferably, the oil supply pipeline is connected with the cooling unit, and the change of the oil temperature is adjusted in real time through the cooling unit, so that the constant oil supply temperature is achieved. And a thermometer 3.2 and a second platinum thermal resistor 4.2 for measuring the oil temperature are arranged close to the oil supply port DN 25.
Specifically, the cooling unit includes a cooler 18, a cooling water inlet pipeline, and a cooling water outlet pipeline. The cooling water inlet pipeline and the cooling water outlet pipeline are respectively communicated with the cooler 18, an electric ball valve 20 is arranged on the cooling water inlet pipeline, and the electric ball valve 20 is configured to complete flow regulation of cooling water entering the cooler 18 based on oil temperature information at an oil outlet DN25 measured by a second platinum thermal resistor 4.2.
Furthermore, a Y-shaped filter 19 for filtering the cooling water is further arranged on the cooling water inlet pipeline. Through the arrangement of the Y-shaped filter 19, the water inlet quality of the cooling water is ensured, and the damage of impurities in the water to the cooling region device 18 is avoided, so that the purpose of prolonging the service life of the cooling device 18 is achieved.
And an oil liquid driving unit is arranged at the joint of the oil supply pipeline and the oil tank 1. The oil liquid drive unit provides power for oil liquid in the oil tank 1 to enter the oil supply pipeline.
The oil liquid driving unit comprises a servo motor 9.1/9.2 and a pump 10.1/10.2. The servo motor 9.1/9.2 is used for driving the pump 10.1/10.2.
The oil supply pipeline is provided with a flow sensor 22 for monitoring the output oil quantity at a position close to the oil supply port DN25, and the servo motor 9.1/9.2 is configured to complete the rotation speed control of the pump 10.1/10.2 based on the flow information measured by the flow sensor 22.

It is well known that the performance indexes of lubricating oils are best at 40 ℃. In fact, the conventional lubricating oil station has the common defect that the oil supply temperature range is large and constant temperature cannot be realized. The existing lubricating station generally has the problems that the temperature of oil supply oil is increased because the water supply amount of a cooler is not changed along with the increase of the temperature of return oil, so that the lubricating effect cannot reach an ideal state. By adopting the thin oil lubricating system, the water inlet flow of the cooler 18 can be adjusted in real time according to the change of the oil temperature, so that the constant oil supply temperature is achieved.
Meanwhile, in the conventional system, when the displacement of the pump 10.1/10.2 and the rotating speed of the motor are determined, the output flow of the pump is determined. However, the output flow of the pump is often greater than the required supply flow, so a bypass is typically provided at the supply port, regulated by a shut-off valve, to return excess flow to the tank. Whereas shut-off valves are manual, requiring a visit to the site for each adjustment, and manual adjustments are not accurate. After the thin oil lubricating system is adopted, the rotating speed of the servo motor 9.1/9.2 is adjustable, and the output flow of the pump is adjustable. And the oil feeding port is provided with a flow sensor 22 for monitoring the flow in real time and feeding back a signal to the control unit, the control unit sends a signal to the servo driver, the servo driver controls the rotating speed of the servo motor, the oil feeding flow is accurately kept at a constant value as required, the output power of the motor is matched along with the flow of the system, and the electric energy is saved to a certain extent.
The traditional thin oil lubrication station needs to be manually adjusted in both flow adjustment and temperature adjustment, and manual adjustment is not only troublesome but also low in precision. After adopting this patent thin oil lubricating system, the oil station is more intelligent, and the user only need set up the flow and the temperature that need in well accuse, and the system just can automatically regulated fuel feeding flow and temperature. And because the flow of pump export is adjustable, what the user needs, the pump just provides, has reduced the waste of power, and is more energy-conserving.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
