Description

Technical Field

[0001] The present application relates to the field of lubrication system heating technology, and in particular to a small heating device used at the end of an oil circuit of a lubrication system. Background Art

[0002] The oil circuit of the lubrication system is an indispensable part of mechanical equipment. Its main function is to form an oil film between moving parts to reduce direct contact between metal surfaces, reduce friction and wear, thereby improving mechanical efficiency and extending equipment life. In addition, lubricating oil can also carry away the heat generated by friction through circulation, helping the equipment to maintain a reasonable temperature range and avoid damage caused by overheating. However, with the diversification of industrial production environments, especially in extreme climatic conditions, the performance of lubrication systems faces new challenges. In particular, in cold environments, the dynamic viscosity of lubricating oil increases significantly, resulting in poor fluidity and affecting the normal operation of equipment. In order to cope with this problem, the industry currently generally adopts a variety of measures to ensure the smooth circulation of lubricating oil. Common methods include using low-viscosity lubricating oil, adding antifreeze, regularly changing lubricating oil, and preheating lubricating oil. Specifically, the use of low-viscosity lubricating oil can reduce the viscosity at low temperatures, but the cost is high and the scope of application is limited; adding antifreeze can improve the fluidity of lubricating oil to a certain extent, but it may affect the chemical properties of lubricating oil; although regular replacement of lubricating oil is effective, it is cumbersome in actual operation and has high maintenance costs; and preheating treatment is a more direct method, which heats the lubricating oil through an external heating device to restore it to a suitable working state, but the existing preheating methods often have problems such as uneven heating and high energy consumption. Although the above methods can alleviate the fluidity problem of lubricating oil in low temperature environments to a certain extent, there are still some shortcomings. For example, the use of low-viscosity lubricating oil and antifreeze may increase operating costs and have an adverse effect on the performance of lubricating oil; regular replacement of lubricating oil is not only time-consuming and labor-intensive, but also increases the maintenance cost of equipment; and although the existing preheating method can increase the temperature of lubricating oil, the problems of uneven heating and high energy consumption have not been effectively solved. Therefore, there is an urgent need for a small heating device that can efficiently and evenly heat lubricating oil in a low temperature environment to ensure the smooth flow of lubricating oil and the normal operation of equipment.

[0005] By adopting the above technical solution, the heating joint body is installed on the oil pipe and can slide along the oil pipe, so that the heating position can be adjusted according to actual needs to ensure that the heating effect is evenly distributed; an annular heater is arranged in the heating joint body, and the annular heater is sleeved on the oil pipe and cooperates with the gap of the oil pipe.

[0008] In a specific possible implementation manner, the heating element further includes a temperature controller, and the annular heater is electrically connected to the temperature controller.

[0009] By adopting the above technical solution, the annular heater is electrically connected to the temperature controller, and the working state of the annular heater can be automatically controlled according to the set temperature, ensuring that the lubricating oil is effectively heated in a low temperature environment, avoiding the increase in viscosity and surface tension of the lubricating oil due to too low temperature, thereby allowing the lubricating oil to be more smoothly transported to the part to be lubricated.

[0010] In a specific possible implementation manner, the heating element further includes a temperature sensor, a deep hole is opened on the inner side wall of the installation groove, the temperature sensor is installed in the deep hole, and the temperature sensor is electrically connected to the temperature controller.

[0012] In a specific possible implementation manner, the gap between the temperature sensor, the annular heater and the inner wall of the mounting groove is filled with thermally conductive silica gel.

[0013] By adopting the above technical solution, the thermally conductive silicone filled in the gap between the temperature sensor, the annular heater and the inner wall of the mounting groove enhances the thermal conductivity between the temperature sensor and the annular heater, ensuring that the temperature sensor accurately detects the operating temperature of the annular heater, thereby achieving more precise temperature control and avoiding poor lubrication problems caused by decreased fluidity of the lubricating oil due to low temperature.

[0021] The embodiment of the present application discloses a small heating device for the end of an oil circuit of a lubrication system.

[0022] like Figure 1 As shown, a small heating device for the end of the oil circuit of the lubrication system includes an oil pipe, a brush assembly, and a heating structure body. The heating joint body 3 is installed on the oil pipe 1, and a double-taper ferrule 4 is installed at one end of the oil pipe 1. A locking groove 21 is provided on the oil outlet body, and one end of the oil pipe 1 with the double-taper ferrule 4 is installed in the locking groove 21. The heating joint body 3 is slidably connected to the oil pipe 1. A tightening block 5 is provided on the heating joint body 3. The tightening block 5 is located between the heating joint body 3 and the double-taper ferrule 4. The outer surface of the tightening block 5 is provided with an external thread, and the inner side wall of the locking groove 21 is correspondingly provided with an internal thread. The tightening block 5 can be threadedly connected in the locking groove 21 and is set against the double-taper ferrule 4. A heating element 6 is provided in the heating joint body 3, and the oil pipe 1 is locally heated by the heating element 6, so that the lubricating oil can still maintain good fluidity under low temperature conditions.

[0023] The outer surface of the lower end of the heating joint body 3 is provided with a screwing portion 7, and the cross section of the screwing portion 7 is set to a polygon. The design of the screwing portion 7 is convenient for the user to manually screw the abutting block 5, which is convenient for installation and disassembly.

[0024] The heating element 6 includes an annular heater 61, a thermostat 62 and a temperature sensor 63. A through hole is provided on the heating joint body 3, a mounting groove 31 is provided on the inner wall of the through hole, the oil pipe 1 is arranged through the through hole, and the heating element 6 is installed in the mounting groove 31. The annular heater 61 is sleeved with the oil pipe 1 and has a clearance fit with the oil pipe 1. This clearance fit ensures that the annular heater 61 uniformly heats the lubricating oil in the oil pipe 1. In the embodiment of the present application, the annular heater 61 adopts a ceramic annular heater 61. The ceramic annular heater 61 is adopted because it has excellent insulation and stability, high heating efficiency and long service life. The ceramic annular heater 61 has a wide operating temperature range and is suitable for various harsh environments, especially cold climates, and can maintain a stable heating effect.

[0025] The annular heater 61 is configured as a ceramic annular heater 61. The ceramic annular heater 61 has good insulation and high temperature resistance and is suitable for long-term continuous operation. The shape of the ceramic annular heater 61 can be circular, square or other geometric shapes, and the specific shape can be selected according to the actual installation space. The thickness of the ceramic annular heater 61 can be adjusted according to the required heating power. Generally, the thickness is between 1-3 mm.

[0026] Among them, the material of the ring heater 61 can be selected as a carbon fiber ring heater 61. The carbon fiber ring heater 61 has the characteristics of light weight, high strength, and good thermal conductivity, and is particularly suitable for use in high-performance equipment such as aerospace, high-speed trains, etc. The thickness of the carbon fiber ring heater 61 can be adjusted according to the required heating power, and is generally more suitable between 0.5-2mm. The shape of the carbon fiber ring heater 61 can be flat, wavy or other special shapes, and the specific shape should be selected according to the actual installation space. For example, the flat carbon fiber ring heater 61 is suitable for narrow spaces, and the wavy carbon fiber ring heater 61 is suitable for occasions that require a large surface area for heat transfer.

[0027] The shape of the annular heater 61 can also be set to a spiral shape. The spiral annular heater 61 can increase the contact area with the oil pipe 1 and improve the heating efficiency. The pitch and diameter of the spiral annular heater 61 should be adjusted according to actual needs. Generally, the pitch is between 1-5mm and the diameter is between 2-10mm. The installation method of the spiral annular heater 61 can be welding, bonding or embedding. The specific method should be selected according to the actual working conditions. For example, welding is suitable for high temperature and high pressure environments, bonding is suitable for low temperature and low pressure environments, and embedding is suitable for occasions that require frequent disassembly and assembly.

[0028] The ring heater 61 can also be installed in a magnetic way. The magnetic ring heater 61 is adsorbed on the oil pipe 1 by a magnet, and no additional fixing device is required, so it is very convenient to install and disassemble. The magnet material of the magnetic ring heater 61 can be selected from neodymium iron boron magnets or samarium cobalt magnets, both of which have strong magnetic force and stable performance. The shape of the magnetic ring heater 61 can be a circular ring, a rectangular strip or other geometric shapes, and the specific shape should be selected according to the actual installation space. During the installation of the magnetic ring heater 61, attention should be paid to the polarity of the magnet to obtain the best adsorption effect.

[0029] A deep hole 32 is opened on the inner wall of the installation groove 31, and the temperature sensor 63 is installed in the deep hole 32. The temperature sensor 63 and the annular heater 61 are electrically connected to the temperature controller 62 through a wire, and the gap between the temperature sensor 63, the annular heater 61 and the inner wall of the installation groove 31 is filled with thermal conductive silicone.

[0030] The thermostat 62 can set the upper and lower limits of the heating temperature. When the temperature of the lubricating oil in the oil pipe is lower than the set lower limit, the thermostat 62 automatically starts the annular heater. When the temperature reaches the set upper limit, the thermostat 62 automatically stops the annular heater. This can avoid overheating and extend the service life of the heating element.

[0031] like Figure 2 As shown, a tightening groove 51 is provided on the end face of the tightening block 5 facing the double-cone ferrule 4. The tightening groove 51 is arranged corresponding to the double-cone ferrule 4 to ensure the sealing between the heating joint body 3 and the oil pipe 1 and avoid leakage of lubricating oil. The tightening groove 51 is arranged as an inclined groove, and is arranged obliquely outward from the side adjacent to the oil pipe 1 to the side away from the oil pipe 1. At the same time, in other embodiments, the inclined groove can be arranged as a trapezoidal groove and a V-shaped groove. The use of the trapezoidal groove can make the tightening block 5 easier to embed into the double-cone ferrule 4, thereby improving the assembly efficiency. The V-shaped groove can enhance the sealing effect to a greater extent because it can apply pressure in a wider area. The design of the wedge-shaped groove focuses more on realizing the self-locking function during the assembly process, that is, as the pressure of the heating joint body 3 increases, the wedge-shaped groove can better bite the double-cone ferrule 4, thereby improving the reliability of the connection.

[0032] The implementation principle of a small heating device for the end of the oil circuit of a lubrication system in the embodiment of the present application is as follows: by setting a heating joint body 3 on the oil pipe 1 and integrating a heating element 6 in the heating joint body 3, the operation of the entire lubrication system is no longer affected by the low temperature environment. The selection of the heating element 6 not only improves the heating efficiency, but also takes into account safety and economy. Through reasonable structural design, the sealing of the device is ensured, and problems such as lubricating oil leakage caused by uneven heating are avoided.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
