Description

Technical Field

[0001] This invention relates to the field of compressor oil tank replenishment technology, and particularly to an oil tank replenishment device. Background Technology

[0002] Compressors are core power equipment in industrial production and oil and gas extraction, and are widely used in special scenarios such as fuel-driven operations and remote gas well extraction. The oil tank, as a critical component for compressor reliability, directly affects the equipment's operating efficiency and service life due to the stability of its oil level.

[0003] Currently, most oil tank replenishment methods in the industry are manual. However, manual replenishment relies on manual inspection and monitoring of oil levels, which is not only labor-intensive and inefficient, but also prone to errors such as missed replenishment, incorrect replenishment, or over-replenishment in remote gas wells and field operations, seriously affecting the continuous operation of equipment. In addition, most existing replenishment devices use electrically driven oil pumps, which rely on external power. However, in gas-driven compressors or remote areas without electricity, power supply is limited, making such devices unsuitable and extremely limited in applicable scenarios.

[0004] Therefore, this application provides a fuel tank replenishment device to meet the demand. Summary of the Invention

The top of the outer screw cap has an air inlet, the input end of which is sealed and connected to the output end of the second ball valve. An inner screw cap is sealed and fixed to the inner wall of the outer screw cap. A spiral air passage is formed between the outer screw cap and the inner screw cap. The top of the inner screw cap has an air guide hole. The input end of the spiral air passage is connected to the air inlet, and the output end of the spiral air passage is connected to the air guide hole. The width of the spiral air passage gradually decreases.

[0008] Optionally, the outer screw cap has a sealing cap fixedly connected to its end wall, a main shaft is rotatably connected to the inner wall of the middle part of the sealing cap, a turbo fan is fixedly installed on the front wall of the main shaft and the turbo fan is located inside the inner screw cap, a connecting seat is fixedly installed on the outer wall of the end of the sealing cap, the main shaft passes through the connecting seat and is rotatably connected to the inner wall of the middle part of the connecting seat, an oil guide groove is provided on the inner wall of the middle part of the connecting seat, two sets of lubrication grooves are provided on the outer wall of the main shaft and the lubrication grooves are used in conjunction with the oil guide grooves, and an oil inlet is provided on the outer wall of the connecting seat and the oil inlet is connected to the oil guide groove.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects:

[0012] In the above solution, by setting up a driven oil replenishment component, the pressurized gas from the original pressurized gas pipeline of the gas well is used as the driving source to drive the drive mechanism. After the speed reduction effect of the planetary reduction mechanism, the oil replenishment mechanism is activated to replenish the oil tank. No external power supply is required, which perfectly solves the problem that traditional electric oil replenishment devices cannot be used in scenarios without electricity, such as gas-driven compressors and remote gas wells, and greatly expands the scope of application.

[0013] By setting up two sets of ball valves in conjunction with the oil level gauge in the oil tank, the system automatically replenishes oil when the oil level in the tank is lower than the preset value and automatically stops when the level reaches the target. This eliminates the need for manual inspection and monitoring, completely solving the problems of high labor intensity, low efficiency, missed replenishment, incorrect replenishment, and excessive replenishment when manually replenishing oil, thus ensuring the continuous and stable operation of the equipment.

[0017] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0018] The present invention provides a fuel tank replenishment device in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0019] like Figures 1 to 15As shown, an embodiment of the present invention provides an oil tank replenishment device, including a driven replenishment component 100 and a base 200. The driven replenishment component 100 is mounted on the base 200. A pressurized gas supply pipe 210 is provided on the top of the base 200, and the pressurized gas supply pipe 210 pressurizes an external gas well. The driven replenishment component 100 is composed of a drive mechanism 110, a planetary reduction mechanism 140, and a replenishment mechanism 150. The drive mechanism 110 can provide power to the replenishment mechanism 150. A ball valve 220 is fixedly installed in the middle of the pressurized gas supply pipe 210, and a ball valve 230 is fixedly installed on a branch pipe at the front end of the pressurized gas supply pipe 210. The ball valve 220 and the ball valve 230 are in an on / off state. Conversely, the oil replenishment mechanism 150 includes a pump outlet housing 151, with an impeller 156 rotatably connected to the inner wall of the middle part of the pump outlet housing 151. An oil inlet pipe 152 and an oil outlet pipe 153 are respectively fixedly installed on the two side walls of the pump outlet housing 151. The oil inlet pipe 152 is connected to an external oil replenishment tank, and the oil outlet pipe 153 is connected to an external oil tank. An oil level gauge is installed inside the oil tank, and the oil level gauge is electrically connected to a second ball valve 230. In this invention, when the oil level inside the oil tank is lower than the preset oil level of the oil level gauge, the oil level gauge can send an electrical signal to the second ball valve 230, causing the second ball valve 230 to open. At this time, the drive mechanism 110 works, and the oil replenishment mechanism 150 can be made to work through the planetary reduction mechanism 140, thereby replenishing the oil tank.

[0020] As one implementation method in this embodiment, such as Figure 1 , Figures 11 to 15As shown, the drive mechanism 110 includes an outer screw cap 111. An air inlet 112 is provided on the front wall of the outer screw cap 111. The output end of the air inlet 112 is sealed and connected to the end of the booster air supply pipe 210, with the connection point located behind the ball valve 220. This pipe is a one-way passage, meaning that gas can only flow into the booster air supply pipe 210 through the air inlet 112. This effect can be achieved by installing a one-way valve at the connection point. An air inlet 11 is provided on the top of the outer screw cap 111. 3. The input end of the air inlet 113 is sealed and connected to the output end of the ball valve 230. An inner screw cap 114 is sealed and fixed to the inner wall of the outer screw cap 111. A spiral air passage 116 is opened between the outer screw cap 111 and the inner screw cap 114. An air guide hole 115 is opened at the top of the inner screw cap 114. The input end of the spiral air passage 116 is connected to the air inlet 113, and the output end of the spiral air passage 116 is connected to the air guide hole 115. The width of the spiral air passage 116 gradually decreases. The narrowing of the spiral air passage 116 can greatly increase the flow rate of the gas within it. In this invention, when the oil level in the internal oil tank of the drive device is lower than the standard line of the oil level gauge, the oil level gauge sends an electrical signal to ball valve 230, causing ball valve 230 to open and ball valve 220 to close. At this time, the pressurized gas in the pressurized gas delivery pipe 210 enters the spiral air passage 116 through ball valve 230 and inlet 113. Under the guidance of the spiral air passage 116, the flow rate of the pressurized gas gradually increases. Subsequently, it enters the inner screw cap 114 through the air guide hole 115, thereby driving the turbine fan 122 to rotate. Finally, it is discharged from the air delivery port 112 at the front end of the outer screw cap 111 into the pressurized gas delivery pipe 210 (this pipe is a one-way passage, that is, the gas can only flow into the pressurized gas delivery pipe 210 through the air delivery port 112, which can be achieved by setting a one-way valve at the connection point), and continues to perform pressurization.

[0021] In this embodiment, as Figures 9 to 15As shown, a cover 120 is fixedly connected to the end wall of the outer screw cap 111, which seals the outer screw cap 111 and the inner screw cap 114. A main shaft 121 is rotatably connected to the inner wall of the middle part of the cover 120. A turbofan 122 is fixedly installed on the front wall of the main shaft 121, and the turbofan 122 is located inside the inner screw cap 114. The pressurized gas can directly drive the turbofan 122 to rotate, so that the turbofan 122 drives the main shaft 121 to rotate. A coupling 130 is fixedly installed on the outer wall of the end of the cover 120. The main shaft 121 passes through the coupling 130 and is rotatably connected to the inner wall of the middle part of the coupling 130. The coupling 130 supports the main shaft 121. An opening is formed in the inner wall of the middle part of the coupling 130. The main shaft 121 has an oil guide groove 131 and two sets of lubrication grooves 123 on its outer wall. The lubrication grooves 123 and the oil guide groove 131 are used in conjunction. The outer wall of the coupling 130 has an oil inlet 132, which is connected to the oil guide groove 131. In this invention, when the turbine fan 122 drives the main shaft 121 to rotate, the main shaft 121 rotates at a high speed. Ordinary bearings are easily damaged due to the high speed during use. At this time, lubricating oil is introduced into the oil guide groove 131 through the oil inlet 132, so that the lubricating oil flows into the two sets of lubrication grooves 123, thereby lubricating the rotation between the main shaft 121 and the coupling 130, which can effectively improve the service life of the mechanism.

[0022] As one implementation method in this embodiment, such as Figures 3 to 5 As shown, a drive gear 124 is fixedly installed on the end wall of the main shaft 121. The outer wall of the front end of the planetary reduction mechanism 140 is fixedly connected to the end wall of the coupling 130. The drive gear 124 is used in conjunction with the input end of the planetary reduction mechanism 140. A driven shaft 141 is fixedly installed on the output end of the planetary reduction mechanism 140. The planetary reduction mechanism 140 converts the rotation of the main shaft 121 into the rotation of the driven shaft 141 and reduces the speed of the rotation of the main shaft 121. Since the pressure of the booster gas is relatively high, it can drive the turbofan 122 to rotate at high speed, thereby driving the main shaft 121 fixed to the turbofan 122 to rotate at high speed. If the speed of the main shaft 121 is not reduced and its speed is directly transmitted to the impeller 156, the pumping speed of the impeller 156 will be accelerated, which does not meet the oil replenishment requirements of the oil tank.

[0023] As one implementation method in this embodiment, such as Figure 1 , Figures 2 to 7As shown, the pump housing 151 is fixedly connected to the outer wall of the end of the planetary reduction mechanism 140. The coupling 130, the planetary reduction mechanism 140, and the bottom of the pump housing 151 are all fixedly connected to the base 200. The driven shaft 141 rotates through the inner wall of the middle section of the front end of the pump housing 151. A sealing ring 154 is engaged with the inner wall of the middle section of the pump housing 151. The sealing ring 154 can seal the connection between the driven shaft 141 and the pump housing 151 to prevent oil from flowing out of the pump housing 151. A sealing cover 155 is fixedly installed on the inner wall of the pump housing 151, and the sealing ring 154 is also fixedly connected to the base 200. 54 contacts the inner wall of the sealing cover 155. The driven shaft 141 is rotatably connected to the sealing ring 154 and the inner wall of the sealing cover 155. The sealing cover 155 can protect and fix the sealing ring 154. The end wall of the driven shaft 141 is fixedly connected to the impeller 156. In this invention, after the main shaft 121 is slowed down by the planetary reduction mechanism 140, it can drive the impeller 156 to work through the driven shaft 141, thereby drawing out the oil in the oil tank connected to the oil inlet pipe 152 and discharging it into the internal oil tank of the drive device through the oil outlet pipe 153.

[0024] The working principle of the technical solution provided by this invention is as follows: When the oil level in the internal oil tank of the drive device is lower than the standard line of the oil level gauge in the tank, the oil level gauge sends an electrical signal to ball valve 230, causing ball valve 230 to open and ball valve 220 to close. At this time, the pressurized gas in the pressurized gas delivery pipe 210 enters the spiral air passage 116 through ball valve 230 and air inlet 113. Under the guidance of the spiral air passage 116, the flow rate of the pressurized gas gradually increases. Then, it enters the inner screw cover 114 through the air guide hole 115, thereby driving the turbofan 122 to rotate. Finally, it is discharged into the pressurized gas delivery pipe 210 through the air outlet 112 at the front end of the outer screw cover 111 (this pipeline is a one-way passage, that is, the gas can only be discharged from the air outlet 112). 12 flows into the booster gas pipe 210 (a one-way valve can be installed at the connection point to achieve this), and continues to boost the pressure. At the same time, the turbofan 122 can drive the main shaft 121 to rotate. After the speed reduction by the planetary reduction mechanism 140, it can drive the impeller 156 to work through the driven shaft 141, thereby drawing out the oil in the replenishment tank connected to the oil inlet pipe 152 and discharging it into the internal oil tank of the drive device through the oil outlet pipe 153, so that the oil level in the oil tank rises. When the oil level exceeds the preset standard, the oil level gauge stops sending an electrical signal to the ball valve 230, causing the ball valve 230 to close and the ball valve 220 to open. At this time, the booster gas in the booster gas pipe 210 is directly boosted through the ball valve 220.

Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0026] The above description is only a preferred embodiment of the present invention.
