[0038] The inventor of the present application found that in the existing lubricating oil system, the cooler is continuously connected with the lubricating oil pipeline, and the energy consumption is large in the long-term running state. Therefore, the present application mainly adopts the scheme of self-operated temperature control valve cooperating with plate cooler, so as to automatically adjust the opening and closing of the cooler according to the temperature of the lubricating oil, thereby significantly reducing the energy consumption of the system. The present application is further described in detail as follows.

[0039] Referring to Figure 1 , Figure 2 and Figure 3 , a new type of lubricating oil packaging device comprises an oil tank 1, an oil supply pump 11, an oil supply pipeline 12, a self-operated temperature control valve 13 and a plate cooler 14. Among them, the oil supply pump 11 is integrated on the top of the oil tank 1, and in the present embodiment, the oil supply pump 11 comprises two alternating current pumps and one direct current pump, and the oil supply pump 11 is connected with the oil supply pipeline 12. The self-operated temperature control valve 13 is arranged on the oil supply pipeline 12, and the self-operated temperature control valve 13 is connected with the plate cooler 14 in parallel.

[0040] The oil supply pump 11 usually comprises two parts of motor and pump body. The motor can adopt a three-phase asynchronous motor or a permanent magnet synchronous motor, and the pump body can select a centrifugal pump or a gear pump structure. The motor is connected with the pump body through a shaft coupling to ensure stable power transmission. The pump body is internally provided with an impeller or a gear set for pumping and pressurizing the lubricating oil in the oil tank 1 and then delivering it to the oil supply pipeline 12.

[0041] The oil supply pipeline 12 can be made of stainless steel seamless steel pipe, and the inner wall is polished to reduce fluid resistance. The pipeline is provided with flanges at both ends for easy connection with other components. A pressure gauge can be installed near the outlet of the oil supply pump 11 for real-time monitoring of system pressure.

[0042] The core components of the self-operated temperature control valve 13 are temperature sensing elements and an actuator. The temperature sensing elements can adopt a bimetallic strip or a liquid expansion type design, and the actuator is composed of a valve stem and a valve core. When the temperature of the lubricating oil rises, the temperature sensing element deforms and pushes the valve stem to act, so that the valve core is opened, thereby connecting the plate cooler 14.

[0043] The plate cooler 14 can be made of multiple layers of stainless steel sheets stacked together, and flow channels are formed between each layer of sheets. Cooling water flows in from one side and exchanges heat with the lubricating oil between the sheets. The surface of the sheet can be designed with a corrugated structure, which not only increases the heat exchange area, but also improves the degree of fluid turbulence and enhances the heat exchange effect. Temperature sensors can be provided at the inlet and outlet of the cooler for detecting the cooling effect.

[0044] By the automatic adjustment function of the self-acting temperature control valve 13, the on-demand start-stop of the plate cooler 14 is realized. When the lubricating oil temperature is high, the temperature control valve is opened, and the cooler is started to cool down; when the temperature returns to normal, the temperature control valve is closed, and the lubricating oil is directly supplied. This design not only reduces the system energy consumption, but also prolongs the service life of the cooler, and improves the response speed and stability of the system. Compared with the traditional continuous connection design, this scheme can flexibly adjust the cooling state according to the actual demand, and has significant energy saving effect and reliability improvement.

[0045] A throttle valve 15 is also added to the oil supply pipeline 12. The throttle valve 15 can adopt a needle valve structure, and the valve core is designed in a conical shape. The opening degree is adjusted by rotating the hand wheel to accurately control the oil supply flow. The needle valve has the advantages of high adjustment accuracy and can effectively throttle at a small opening degree, especially suitable for working conditions that require fine flow control. In addition, the throttle valve 15 also has good sealing performance to prevent leakage. By adjusting the opening degree of the throttle valve 15, the system operating point can be optimized to improve overall efficiency.

[0046] Referring to Figure 1 and Figure 4 , for the parts in the equipment that need to be lubricated by the top shaft, a top shaft oil pump 2 and a top shaft oil pipe 21 are added to the top of the oil tank 1. The top shaft oil pump 2 can be selected as a high-pressure plunger pump, which has the characteristics of high output pressure and stable flow. The plunger pump is driven by a motor, which converts rotary motion into linear reciprocating motion through a crank connecting rod mechanism, driving the plunger to reciprocate in the pump cavity to realize the oil suction and discharge process. The top shaft oil pipe 21 can use a high-pressure hose, which is lined with a high-pressure rubber layer and covered with a steel wire braid layer to ensure safe and reliable operation under high pressure. The inlet pipe of the top shaft oil pump 2 is connected to the oil tank 1 through a circulating pipeline 22, and the circulating pipeline 22 is also connected to a circulating oil pump 23. The circulating oil pump 23 is connected to the oil tank 1 and continuously operates to continuously supply oil to the inlet pipe of the top shaft oil pump 2, ensuring that the inlet of the top shaft oil pump 2 is always full of lubricating oil, avoiding air accumulation affecting the start-up response speed.

[0047] Referring to Figure 1 , in order to further improve the purity of the lubricating oil, a filter 16 is also added to the oil supply pipeline 12, which is also integrated at the top of the oil tank 1. The filter 16 can adopt a multi-stage filtering structure, for example, the first stage is a coarse filter screen for intercepting large particle impurities, and the second stage is a precision filter element using a microporous filter membrane material to remove micron-sized particulate matter. The filter 16 shell is made of carbon steel, and the inner and outer surfaces are treated for corrosion resistance. The filter 16 inlet and outlet is provided with a pressure difference table to prompt replacement when the pressure difference exceeds the set value. By setting the filter 16, impurities in the lubricating oil can be effectively removed to protect downstream equipment from pollution damage.

[0048] The oil supply pipeline 12 is also connected with a flow regulating valve 18. The setting of the flow regulating valve 18 can flexibly adjust the flow rate and flow of the lubricating oil in the oil supply pipeline 12, so as to meet the demand for the lubricating oil supply amount under different working conditions, and improve the adaptability and stability of the system.

[0049] With reference to Figure 3 The oil tank 1 is also provided with a ladder 3 on the side, which facilitates the maintenance of the operator. The ladder 3 can be designed with anti-skid, and the handle part is additionally provided with an insulating sleeve to ensure the safety of operation. The top of the oil tank 1 is circumferentially provided with a guardrail 31 as needed, and the height of the guardrail 31 is not less than 1.2 meters, and the spacing is set as needed to prevent accidental falling of personnel.

[0050] In addition, with reference to Figure 5 A partition 17 is also arranged inside the oil tank 1 to form a U-shaped return channel. The partition 17 can be made of stainless steel to ensure the structural strength. The U-shaped channel design prolongs the return path of the lubricating oil, increases the sedimentation time, and is beneficial to the full sedimentation of impurities.

[0051] Through the combination of the above various optimization measures, not only the problem of high energy consumption of the original system is solved, but also the performance and safety of the lubricating oil system are comprehensively improved. The addition of the throttle valve 15 enhances the flow control ability, the configuration of the top shaft oil pump 2 meets the special lubrication demand, the use of the filter 16 improves the quality of the lubricating oil, the U-shaped return channel design promotes the sedimentation of impurities, and the setting of the ladder 3 and the guardrail 31 ensures the safety of operation. These improvement measures cooperate with each other to form an efficient, reliable and safe lubricating oil system solution.

[0052] The above are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
