Description

Technical Field

[0001] This utility model relates to the field of high-level oil tank technology, specifically to a self-adjusting high-level oil tank. Background Technology

[0002] The elevated oil tank is a protective facility primarily used to provide lubricating oil to the equipment by gravity when the main and auxiliary oil pumps interrupt the supply of lubricating oil. This maintains the lubrication needs during the unit's coasting process and prevents equipment damage due to lack of oil. Its main functions include emergency oil supply (providing lubricating oil to components such as bearings in case of power failure or pump failure to prevent dry friction); and lubrication and cooling. During normal operation, oil is continuously supplied to the elevated oil tank through a flow-limiting orifice plate, with overflowing oil flowing back to the main oil tank, ensuring a suitable lubricating oil temperature and providing lubrication and cooling in emergencies.

[0003] Chinese patent CN209744021U discloses a "self-regulating high-level oil tank". This device uses a combination of a level control device, an inlet / outlet oil device, and a return oil device to ensure that the high-level oil tank replenishes the lubrication circuit during emergency shutdown. The level control device also enables automatic control of the oil level in the high-level oil tank, achieving a self-regulating function. However, during use, the temperature of the oil flowing back into the tank can cause the overall oil level to rise. If this rises above the normal range, it can affect the safety of the tank itself and the oil supply. Relying on natural cooling to adjust to the normal level is time-consuming and not timely, which greatly affects the normal and safe use of the high-level oil tank. Utility Model Content

Detailed Implementation

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figures 1-4 The self-adjusting high-level oil tank shown includes: The oil tank body 1 has an oil supply line 2 at the bottom and a first solenoid valve 3 at the top. A return oil line 4 is provided on one side of the oil tank body 1 and a second solenoid valve 5 is provided at the end of the return oil line 4 near the oil tank body 1. The oil supply line 2 can distribute the oil in the oil tank body 1 to the oil-using equipment, and the first solenoid valve 3 can open and close the oil supply line 2. The return oil line 4 can be connected to the equipment to form a loop, so that the oil can flow back to the oil tank body 1. The second solenoid valve 5 is used to control the opening and closing of the return oil line 4.

[0017] An oil filling pipe 7 is installed at the top of the oil tank body 1, and a third solenoid valve 8 is installed at the bottom of the oil filling pipe 7. Based on this, the opening and closing of the oil filling pipe 7 can be controlled by the third solenoid valve 8, and the oil filling pipe 7 can replenish oil into the oil tank body 1 in a timely manner.

[0018] A drain pipe 18 is provided on one side of the bottom of the oil tank body 1, and a drain valve 19 is provided at one end of the drain pipe 18. Based on this, the opening and closing of the drain pipe 18 can be controlled by the drain valve 19, and the drain pipe 18 can discharge the oil and dirt deposited at the bottom of the oil tank body 1.

[0019] The fuel tank body 1 is equipped with a fixing seat 6 at each of its four ends, and the side wall of the fixing seat 6 is provided with fixing holes. Based on this, the fuel tank body 1 can be installed and fixed through the fixing seat 6.

[0020] A temperature sensor 21 and a liquid level sensor 22 are installed on the top side inside the oil tank body 1. The temperature sensor 21 can detect the oil temperature inside the oil tank body 1, and the liquid level sensor 22 can detect the oil level inside the oil tank body 1.

[0021] An oil extraction pipe 9 is provided at the bottom of the side wall of the oil tank body 1, and an oil delivery pipe 11 is provided at the top of the side wall of the oil tank body 1 near the oil extraction pipe 9. A fourth solenoid valve 10 is provided at the end of the oil extraction pipe 9 and the oil delivery pipe 11 near the oil tank body 1. An oil pump 13 is connected to the other end of the oil extraction pipe 9. The oil outlet of the oil pump 13 is connected to the first oil collection cylinder 12 through a pipe. One end of the oil delivery pipe 11 is connected to the booster oil pump 16. The oil inlet of the booster oil pump 16 is connected to the second oil collection cylinder 15 through a pipe. Multiple spiral pipes 14 are provided between the second oil collection cylinder 15 and the first oil collection cylinder 12.

[0024] When the temperature sensor 21 detects that the oil temperature inside the oil tank body 1 exceeds the set value range, the fourth solenoid valve 10 can open the oil extraction pipe 9 and start the oil pump 13. The oil pump 13 can draw the oil in the oil tank body 1 into the first oil collection cylinder 12 through the oil extraction pipe 9. Then, the oil in the first oil collection cylinder 12 can flow into each spiral pipe 14 and be collected into the second oil collection cylinder 15. Since the spiral pipes 14 are exposed and the fan 20 blows air onto the spiral pipes 14, the spiral pipes can be quickly conditioned. The oil in the first oil collector 12 undergoes heat exchange, and the design of the spiral pipeline 14 can greatly extend the oil flow path to further increase the heat exchange time. Then, the oil in the second oil collector 15 can flow back to the main body of the oil tank 1 through the open oil delivery pipe 11. In addition, the oil in the first oil collector 12 can be further cooled by the cooling plate 17. Through continuous circulation and heat dissipation, the oil temperature in the main body of the oil tank 1 can be restored to the normal range, thereby effectively realizing the self-regulation of the high-pressure oil tank temperature and greatly ensuring the safety and effectiveness of oil use.
