Description

Technical Field

[0001] The utility model relates to the technical field of water cooling equipment, in particular to a lubricating oil water cooling device for a wall-reducing machine. Background Art

[0002] Wall-reducing machines are widely used in the metalworking industry, primarily for reducing the wall thickness of metal pipes to meet diverse application requirements. During this process, the metal pipes undergo intense tensile deformation, generating significant heat. If this heat is not dissipated promptly and effectively, it can not only affect processing quality and production efficiency but can also lead to overheating and damage to the equipment. Therefore, effectively cooling the lubricating oil in wall-reducing machines has become a critical issue in this field.

[0003] Existing methods for cooling lubricating oil in wall-reducing machines mainly include air cooling, natural heat dissipation, and water cooling. Among them, the air cooling method uses a fan to blow away heat, which is suitable for small equipment, but the cooling effect is not good for large equipment and under high-load conditions. Natural heat dissipation relies on the natural flow of ambient air, has low cooling efficiency, and is difficult to meet the needs of industrial production. Water cooling is one of the most commonly used methods. The cooling water is transported to the heat exchanger through a circulating water pump, and the heat exchanger then transfers the heat to the external environment. However, the traditional water cooling system has some shortcomings, such as a single cooling water circulation path, inability to flexibly adjust, and insufficiently precise cooling water temperature control.

[0004] In practical applications, existing water cooling systems are often unable to cope with complex changes in working conditions. Therefore, there is an urgent need for a wall-reducing machine lubricating oil water cooling device that can effectively solve the above problems. Utility Model Content

When in use, a cooling water tank is used to provide cooling water. The water in the cooling water tank is provided through a tap water inlet pipe. The cooling water in the cooling water tank provides cooling water to the heat exchanger. When the water temperature in the cooling water tank is too high, the heat exchanger is directly connected to the tap water inlet pipe to extract water.

At the same time, the sealing cover design can prevent water evaporation and external impurities from entering, ensuring stable operation of the system.

[0020] By adopting the above technical solution, when in use, the observation window can intuitively understand the water level in the cooling water tank without relying on electronic equipment, avoiding equipment failure caused by too low or too high water level, and improving the reliability and safety of the system.

[0021] Preferably, a water level sensor and a temperature sensor are installed in the cooling water tank so as to automatically control the water replenishment and replacement operations according to the water temperature and water volume.

[0022] By adopting this technical solution, the water level sensor and temperature sensor installed in the cooling water tank can monitor the water temperature and water volume in real time during use, ensuring the stable operation of the cooling system.

[0031] Example 1

[0032] The utility model discloses a lubricating oil water cooling device for a wall reducing machine, such as Figure 1 As shown, it includes a cooling water tank 1, a water tank supply pipe 2 is provided on the top of the cooling water tank 1, the water tank supply pipe 2 is connected to the tap water inlet pipe 3, and a first solenoid valve 9 is installed on the water tank supply pipe 2. The first solenoid valve 9 controls the opening and closing of the water tank supply pipe 2.

[0033] A heat exchanger 4 is also provided on one side of the cooling water tank 1. A water inlet pipe 5 and a water outlet pipe 6 are provided on both sides of the heat exchanger 4. A circulating pump 10 is provided on one side of the cooling water tank 1. The circulating pump 10 is a centrifugal pump with high flow and head. A pumping pipe 11 is connected to the circulating pump 10. The pumping pipe 11 is connected to the water inlet pipe 5 of the heat exchanger 4. A filter can be installed on the pumping pipe 11 to filter impurities in the water and prevent clogging of the heat exchanger 4. The filter can be made of stainless steel or nylon, which has good corrosion resistance and filtering effect. A cooling feed pipe 7 is connected to the end of the water inlet pipe 5. The cooling feed pipe 7 is connected to the tap water inlet pipe 3. When the water temperature in the cooling water tank 1 is too high, tap water is directly drawn from the cooling feed pipe 7 for use. A second solenoid valve 12 is provided on the cooling feed pipe 7. The second solenoid valve 12 can also be an electric valve or a pneumatic valve for remote control. When the cooling water temperature is too high, the second solenoid valve 12 will open to introduce low-temperature tap water for cooling.

[0034] The end of the drain pipe 6 is connected to the water tank return pipe 8, which is connected to the cooling water tank 1. A third solenoid valve 13 is provided on the water tank return pipe 8. The selection of the third solenoid valve 13 is consistent with the first solenoid valve 9 and the second solenoid valve 12. An electric valve or a pneumatic valve can be selected according to actual conditions. The cooling water in the heat exchanger 4 can be recycled. The third solenoid valve 13 will be opened to allow the cooled water to flow back into the cooling water tank 1, forming a closed-loop cooling system. This design can effectively replenish and replace the cooling water, ensure the stable operation of the cooling system, and thus improve the working efficiency and service life of the wall reducing machine.

[0035] The cooling water tank 1 is also equipped with a water level sensor 16 and a temperature sensor 17. The water level sensor 16 is used to monitor the water level in the cooling water tank 1, and the temperature sensor 17 is used to monitor the temperature of the cooling water. These sensors can transmit data to the control system to achieve automated water replenishment and water replacement operations.

[0036] Working Principle: This utility model designs a water-cooling device for lubricating oil in a wall-reducing machine. By adding a circulating pump 10, the water in the cooling water tank 1 is circulated to the heat exchanger 4, thereby accelerating the heat exchange rate and improving the cooling efficiency. At the same time, the water level sensor 16 and the temperature sensor 17 monitor the water level and temperature in the water tank in real time. When the water level is lower than the preset value, the first solenoid valve 9 will automatically open to replenish cooling water into the water tank; when the water temperature in the cooling water tank 1 exceeds the preset value, the second solenoid valve 12 will open, introducing low-temperature tap water into the heat exchanger 4 for cooling; when the third solenoid valve 13 opens, the cooled water in the heat exchanger 4 will flow back into the water tank, forming a closed-loop cooling system.

[0037] Example 2

[0038] like Figure 2 As shown, this embodiment differs from the previous embodiment in that the cooling water tank 1 is provided with a drain hole 14, which is connected to a sealing cover for replacing the water in the cooling water tank 1. The design of drain hole 14 makes it easier to replace the cooling water, reducing maintenance time and cost. The cooling water tank 1 is also provided with an observation window 15. The observation window 15 is made of transparent glass and allows direct viewing of the water level in the tank. The design of observation window 15 allows the operator to monitor the water level in real time, ensuring that the tank is always in optimal working condition.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
