Description

Technical Field

[0001] This utility model relates to the technical field of cooling tower reducer monitoring equipment, and in particular to a cooling tower reducer oil level monitoring device. Background Technology

[0002] As a core power component of industrial cooling systems, the cooling tower reducer's operational stability directly affects the cooling tower's heat dissipation efficiency and service life. The level and quality of the lubricating oil inside the reducer are critical parameters for ensuring normal equipment operation: too low an oil level leads to insufficient lubrication of gear meshing, causing high-temperature wear or even gear seizure; deteriorated oil quality (such as increased metal particles or oxidation) can accelerate corrosion and fatigue damage to internal reducer components. Therefore, real-time monitoring of the reducer's oil level and quality is a core requirement in industrial equipment maintenance.

[0003] In existing technologies, traditional oil level monitoring methods (such as built-in oil level mirrors, dipsticks, or electronic sensors) suffer from low observation accuracy and susceptibility to contamination or environmental interference, resulting in inaccurate oil level data and the inability to achieve continuous monitoring. Secondly, there is a lack of means to monitor oil quality; existing technologies only focus on oil level while neglecting the real-time detection of metal particles, moisture, or oxidation products in the oil, which can easily lead to sudden equipment failures due to oil quality deterioration. Thirdly, the oil circuit structure design is unreasonable; single-layer oil pipes are easily affected by temperature, leading to unstable oil flow and poor practicality. Therefore, this utility model discloses an oil level monitoring device for cooling tower reducers to solve the problems of inconvenient oil level monitoring, inability to conduct continuous monitoring, and unstable oil flow caused by unreasonable oil circuit structure design in existing technologies.

[0005] To achieve the above objectives, this utility model provides a cooling tower reducer oil level monitoring device, comprising: a reducer, wherein the bottom of the reducer is provided with a conical box bottom, and a first double-layer jacketed oil pipe is installed in the middle of the conical box bottom, and a T-shaped tee connector is installed at the other end of the first double-layer jacketed oil pipe, a second double-layer jacketed oil pipe is installed at the vertical port of the T-shaped tee connector, and a monitoring component is provided at the upper part of the second double-layer jacketed oil pipe, the monitoring component being used to monitor the oil level height in the reducer.

[0006] Preferably, the monitoring component includes a double-layer transparent glass observation box, the bottom of which is installed on the top of the second double-layer jacketed oil pipe. An oil level safety line is provided on the upper part of the side wall of the double-layer transparent glass observation box, an oil replenishment warning line is provided on the side wall of the double-layer transparent glass observation box below the oil level safety line, and a minimum oil level line is provided on the side wall of the double-layer transparent glass observation box below the oil replenishment warning line. A breather valve is provided on the top of the double-layer transparent glass observation box.

[0007] Preferably, a filter box is installed on the other horizontal port of the T-shaped tee joint via a connecting pipe, a third double-jacketed oil pipe is installed on the other side wall of the filter box, and a magnetic filter plate is snapped onto the top of the filter box. A hole is provided on the filter box corresponding to the position of the magnetic filter plate, and a sealing ring is installed at the position where the magnetic filter plate connects with the filter box.

[0008] Preferably, the outer layer of the double-layer transparent glass observation box is explosion-proof tempered glass, the inner layer of the double-layer transparent glass observation box is high borosilicate glass, and a vacuum is set between the explosion-proof tempered glass and the high borosilicate glass.

[0009] Preferably, the outer, middle and inner layers of the first double-jacketed oil pipe and the second double-jacketed oil pipe are composed of a carbon steel layer, a thermally conductive silicone grease layer and a stainless steel layer, and the inner wall surface of the stainless steel layer is coated with anti-rust paint.

[0010] Preferably, a spiral guide vane is installed on the inner wall of the end of the first double-jacketed oil pipe near the bottom of the reducer.

[0011] Preferably, a guide cone is installed inside the T-shaped tee joint via a connector, with the small end of the guide cone facing one end of the reducer.

[0012] The beneficial effects of this utility model are:

[0013] This utility model provides a cooling tower reducer oil level monitoring device that addresses the problems of low observation accuracy and susceptibility to contamination or environmental interference in traditional oil level monitoring methods. This utility model employs a double-layer transparent glass observation box (an outer layer of explosion-proof tempered glass and an inner layer of high borosilicate glass in a vacuum combination) combined with a spiral guide vane and a guide cone structure. By optimizing the oil flow path, it reduces the deposition of air bubbles and impurities, ensuring that the oil level inside the observation box is synchronized with the reducer oil tank in real time. Simultaneously, the combination of the outer explosion-proof glass and the inner high borosilicate glass adapts to extreme temperature differences and has impact resistance. Combined with an oleophobic coating and vacuum layer design, it completely eliminates oil adhesion to the walls and condensate interference, significantly improving observation clarity and stability. Secondly, addressing the lack of oil condition monitoring methods, this utility model integrates a filter box and a detachable magnetic filter plate at the T-shaped tee joint, allowing for real-time adsorption... Metal particles in the oil, combined with the anti-rust paint coating and thermally conductive silicone grease layer on the inner wall of the double-jacketed oil pipe, inhibit oil oxidation and deterioration and prevent water from mixing in. Meanwhile, the side wall of the observation box is equipped with an oil level safety line, an oil replenishment warning line, and a minimum oil level line. Preliminary judgment of oil quality deterioration is achieved by comparing the oil's color and transparency, forming a dual-dimensional monitoring system of oil level and quality. Furthermore, addressing the problem of unstable oil flow caused by unreasonable oil circuit design, this invention uses a double-jacketed oil pipe (a composite structure of carbon steel layer, thermally conductive silicone grease layer, and stainless steel layer) to balance the influence of environmental temperature differences on oil viscosity, avoiding sealing failure due to thermal expansion and contraction of the oil pipe. Simultaneously, the spiral guide vanes and guide cones work together to form a stable laminar flow of oil within the oil pipe, reducing impurity deposition caused by turbulence. Combined with the sealing ring locking structure of the filter box, this addresses the leakage problem of the oil circuit system. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] This utility model provides, for example Figures 1 to 4The cooling tower reducer oil level monitoring device shown includes: a reducer 1, a conical bottom 2 at the bottom of the reducer 1, a first double-jacketed oil pipe 3 installed in the middle of the conical bottom 2, a T-shaped tee connector 4 installed at the other end of the first double-jacketed oil pipe 3, a second double-jacketed oil pipe 5 installed at the vertical port of the T-shaped tee connector 4, and a monitoring component at the upper part of the second double-jacketed oil pipe 5. The monitoring component is used to monitor the oil level in the reducer 1. The cooling tower reducer 1 oil level monitoring device provided by this utility model addresses the shortcomings of traditional oil level monitoring methods. To address the issues of low measurement accuracy and susceptibility to contamination or environmental interference, this invention employs a double-layered transparent glass observation box 6. The outer layer is made of explosion-proof tempered glass, while the inner layer is made of high borosilicate glass, all combined in a vacuum configuration with a spiral guide vane 16 and a guide cone 17. This optimizes the oil flow path, reducing bubble and impurity deposition and ensuring real-time synchronization between the oil level inside the double-layered transparent glass observation box 6 and the oil tank of the reducer 1. Furthermore, the combination of the outer explosion-proof glass and the inner high borosilicate glass not only withstands extreme temperature differences but also provides impact resistance. Combined with an oleophobic coating and vacuum layer design, this completely eliminates oil adhesion to the walls and condensation interference. This invention significantly improves the clarity and stability of observations. Secondly, addressing the lack of oil condition monitoring methods, this invention integrates a filter box 11 and a detachable magnetic filter plate 18 at the T-shaped tee joint 4 to adsorb metal particles in the oil in real time. Combined with the anti-rust paint coating and thermally conductive silicone grease layer 14 on the inner wall of the double-layered jacketed oil pipe, it inhibits oil oxidation and deterioration, as well as water ingress. Simultaneously, the side wall of the double-layered transparent glass observation box 6 is equipped with an oil level safety line 9, an oil replenishment warning line 8, and a minimum oil level line 7. By comparing the oil color and transparency, a preliminary judgment of oil quality deterioration is achieved, forming an oil... A dual-dimensional monitoring system for oil quality and position; furthermore, addressing the problem of unstable oil flow caused by unreasonable oil circuit structure design, this utility model adopts a double-layer jacketed oil pipe (carbon steel layer 13-thermal conductive silicone grease layer 14-stainless steel layer 15 composite structure) to balance the influence of environmental temperature difference on oil viscosity, avoiding sealing failure of the oil pipe due to thermal expansion and contraction. At the same time, the spiral guide vane 16 and the guide cone 17 work together to form a stable laminar flow of oil in the oil pipe, reducing the deposition of impurities caused by turbulence. Combined with the sealing ring locking structure of the filter box 11, the leakage problem of the oil circuit system is solved.

[0025] Furthermore, in this example, such as Figure 3As shown, the monitoring component includes a double-layer transparent glass observation box 6. The bottom of the double-layer transparent glass observation box 6 is installed on the top of the second double-layer jacketed oil pipe 5. An oil level safety line 9 is provided on the upper part of the side wall of the double-layer transparent glass observation box 6. An oil replenishment warning line 8 is provided on the side wall of the double-layer transparent glass observation box 6 below the oil level safety line 9. A minimum oil level line 7 is provided on the side wall of the double-layer transparent glass observation box 6 below the oil replenishment warning line 8. A breather valve 10 is provided on the top of the double-layer transparent glass observation box 6. The lubricating oil in the reducer 1 is collected through the conical box bottom 2 to the first double-layer jacketed oil pipe 3. It is guided by the spiral guide vane 16 to form a spiral flow, so that the air bubbles in the oil rotate and rise along the pipe wall and burst, preventing them from entering the double-layer transparent glass observation box 6. The oil continues to flow to the T-joint 4. Under the guidance of the guide cone 17, the oil enters the second double-jacketed oil pipe 5 in a laminar flow state, eventually forming a stable liquid level in the double-layer transparent glass observation box 6, which is synchronized with the actual oil level in the reducer 1 in real time. The oil level safety line 9, the oil replenishment warning line 8, and the minimum oil level line 7 on the side wall of the double-layer transparent glass observation box 6 provide operators with intuitive oil level range markings. When the oil level is lower than the oil replenishment warning line 8, lubricating oil needs to be replenished in time; if the oil level touches the minimum oil level line 7, it indicates that there is a risk of oil leakage or serious oil shortage, and the machine needs to be stopped immediately for maintenance. At the same time, by observing the color and transparency of the oil, such as turbidity caused by metal particles and darkening caused by oxidation, the oil quality can be preliminarily judged. Combined with regular sampling and analysis, early warning of oil quality deterioration can be achieved. The double-layer transparent glass observation box 6 adopts a vacuum combination structure of an outer layer of explosion-proof tempered glass and an inner layer of high borosilicate glass. The outer glass withstands impact, while the inner glass adapts to high temperature differences. The vacuum layer isolates heat conduction and prevents condensation. The top breather valve 10 discharges excess gas when the oil temperature rises and draws in air when the oil temperature drops, balancing the internal and external pressure differences and preventing the double-layer transparent glass observation box 6 from cracking or leaking oil due to pressure changes.

[0026] Furthermore, in this example, such as Figure 3 and Figure 4As shown, a filter box 11 is installed on the other horizontal port of the T-shaped tee connector 4 via a connecting pipe. A third double-layer jacketed oil pipe 12 is installed on the other side wall of the filter box 11, and a filter plate 18 is snapped onto the top of the filter box 11. Holes are opened on the filter box 11 corresponding to the positions of the filter plate 18, and a sealing ring is installed at the position where the filter plate 18 meets the filter box 11. The outer layer of the double-layer transparent glass observation box 6 is explosion-proof tempered glass, and the inner layer of the double-layer transparent glass observation box 6 is high borosilicate glass. A vacuum is set between the explosion-proof tempered glass and the high borosilicate glass. The outer, middle, and inner layers of the first double-jacketed oil pipe 3 and the second double-jacketed oil pipe 5 are composed of a carbon steel layer 13, a thermally conductive silicone grease layer 14, and a stainless steel layer 15. The inner wall surface of the stainless steel layer 15 is coated with anti-rust paint. A spiral guide vane 16 is installed on the inner wall of the first double-jacketed oil pipe 3 near the bottom of the reducer 1. A guide cone 17 is installed in the T-shaped tee connector 4 through a connector, with the small end of the guide cone 17 facing the reducer 1. The oil pipe is composed of a carbon steel layer 13 providing structural strength, a thermally conductive silicone grease layer 14 balancing the effect of ambient temperature difference on oil viscosity, and a stainless steel layer 15 providing corrosion resistance. The inner wall of the stainless steel layer 15 is coated with anti-rust paint to further inhibit oil oxidation and moisture corrosion. The air layer between the outer carbon steel layer 13 and the inner stainless steel layer 15 in the double-jacketed structure reduces heat conduction, preventing the oil viscosity from decreasing due to high temperature or the oil flow from deteriorating due to low temperature, ensuring stable oil flow within the pipe. A spiral guide vane 16 is installed at the end of the first double-jacketed oil pipe 3 near the reducer 1, causing the oil to flow in a spiral trajectory. Centrifugal force is used to separate air bubbles and impurities in the oil, reducing impurity deposition. A guide cone 17 is installed inside the T-shaped tee connector 4, with its small end facing the reducer 1. This ensures the oil remains in a laminar flow state during diversion, preventing turbulence from generating new air bubbles or impurities and ensuring the oil smoothly enters the second double-jacketed oil pipe 5 and the filter box 11. The oil flows into the filter box 11 through the horizontal port of the T-shaped tee connector 4. When it passes through the magnetic filter plate 18 installed at the top, metal particles in the oil are adsorbed onto the surface of the filter plate 18. Periodic disassembly and cleaning restores the filtration performance. A sealing ring is installed at the joint between the filter box 11 and the filter plate 18 to prevent oil leakage. The filtered oil returns to the reducer 1 through the third double-jacketed oil pipe 12, forming a circulating oil circuit. The modular design of the filter box 11 facilitates quick replacement of the filter plate 18, reducing maintenance costs.
