Description

Technical Field

[0001] This utility model belongs to the field of natural gas compressor technology, and in particular relates to an oil temperature control device for a natural gas compressor lubrication system. Background Technology

[0002] The natural gas compressor lubrication system is designed to meet the operational needs of natural gas compressor equipment. It is an integrated system that lubricates, cools, cleans, and prevents corrosion of the moving parts inside the compressor through the circulation of a lubricating medium (usually lubricating oil). Its core function is to ensure the efficient, safe, and stable operation of the compressor.

[0003] When using lubricating oil in a natural gas compressor, if the oil temperature is low upon entering the machine, the oil viscosity will increase and the fluidity will decrease. At low temperatures, the lubricating oil cannot form a uniform and stable oil film, especially during startup. The boundary lubrication state between components is more easily disrupted, which may lead to dry friction, causing abnormal wear of critical components such as piston rings and bearings, and even jamming or seizing. Therefore, it is necessary to provide a natural gas compressor lubrication system oil temperature control device. This device adds a heating structure to the lubricating oil delivery pipeline to heat the lubricating oil, and also includes a temperature detection structure and a material stirring structure to ensure that the lubricating oil entering the natural gas compressor meets the operating conditions and ensures the stable operation of the natural gas compressor.

[0022] In the following description, embodiments of the oil temperature control device for the lubrication system of the natural gas compressor of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4This invention illustrates an embodiment of a natural gas compressor lubrication system oil temperature control device, comprising a heating tank 1. An inlet pipe 2 is fixedly connected to the bottom right side of the heating tank 1, and an outlet pipe 3 is fixedly connected to the top left side of the heating tank 1. Solenoid valves 12 are fixedly installed on the surfaces of both the inlet pipe 2 and the outlet pipe 3. Temperature sensors 4 are fixedly installed at the top and bottom of the inner cavity of the heating tank 1. Electric heaters 5 are fixedly installed on both sides of the inner cavity of the heating tank 1. A rotating rod 6 is rotatably connected to the bottom of the inner cavity of the heating tank 1. A rotatable rotating sleeve 7 is fitted onto the surface of the rotating rod 6. The tops of both the rotating rod 6 and the rotating sleeve 7 extend to the top of the heating tank 1. A stirring blade 8 is fixedly connected to the top of the rotating sleeve 7 and the bottom of the rotating rod 6. Multiple material discharge holes 11 are provided on the surface of the stirring blade 8. The rotation of the material discharge holes 11 allows the lubricating oil to be distributed in a columnar shape within the inner cavity of the heating tank 1 during stirring, resulting in a more uniform mixing of the lubricating oil. A gearbox 10 is fixedly connected to the top of the heating tank 1. The inner cavity of the gearbox 10 is provided with a drive assembly 9. The drive assembly 9 includes a first gear 91 fixedly connected to the top of the surface of the rotating sleeve 7, a second gear 92 fixedly connected to the top of the surface of the rotating rod 6, a transmission gear 93 rotatably connected to the top of the inner cavity of the gearbox 10, a servo motor 94 fixedly installed on the right side of the top of the gearbox 10, and a drive gear 95 rotatably connected to the right side of the inner cavity of the gearbox 10. The output shaft of the servo motor 94 passes through the inner cavity of the gearbox 10 and is fixedly connected to the drive gear 95. The two sides of the transmission gear 93 mesh with the second gear 92 and the drive gear 95 respectively. The first gear 91 meshes with the drive gear 95. Through the arrangement of the drive assembly 9, the servo motor 94 and the drive gear 95 work together to simultaneously mesh and transmit power to the transmission gear 93 and the first gear 91. At the same time, under the meshing transmission action of the second gear 92, the rotating rod 6 and the rotating sleeve 7 rotate in opposite directions, thereby causing the two stirring blades 8 to rotate in opposite directions, and stirring and mixing the lubricating oil located in the inner cavity of the heating tank 1.

[0024] Working Principle: When using this invention, the user connects the inlet pipe 2 and the outlet pipe 3 to the lubricating oil delivery pipeline. Then, the user turns on the electric heater 5 to heat the lubricating oil entering the inner cavity of the heating tank 1. At the same time, the temperature sensor 4 monitors the temperature of the lubricating oil. During the heating process, the servo motor 94 is turned on and drives the drive gear 95 to rotate. During the rotation of the drive gear 95, it drives the transmission gear 93 and the first gear 91 meshing with it to rotate. At the same time, the transmission gear 93 drives the second gear 92 meshing with it to rotate. The second gear 92 and the first gear 91 are coaxial and rotate in opposite directions, which causes the rotating rod 6 and the rotating sleeve 7 to rotate in opposite directions. Finally, the stirring blade 8 stirs and mixes the lubricating oil in the inner cavity of the heating tank 1 to prevent local differences in lubricating oil stability. When the temperature sensor 4 detects that the temperature meets the usage requirements, the solenoid valve 12 on the left side is opened to deliver the lubricating oil.

[0025] In summary, the oil temperature control device of this natural gas compressor lubrication system heats the lubricating oil entering the inner cavity of the heating tank 1 by using the inlet pipe 2, outlet pipe 3 and electric heater 5 together, and monitors its heating temperature. At the same time, with the cooperation of rotating sleeve 7, rotating rod 6 and stirring blade 8, the lubricating oil in the inner cavity of the heating tank 1 is mixed and stirred, so that the lubricating oil is heated evenly. This achieves the purpose of real-time monitoring of the lubricating oil heating temperature and effectively preventing local temperature differences.
