Description

Technical Field

[0001] This utility model relates to the technical field of lubricating oil monitoring equipment, specifically a turbine lubricating oil flow monitoring and early warning system. Background Technology

[0002] Lubricating oil monitoring equipment is a specialized device used to monitor and analyze various parameters of lubricating oil in real time, assess its health and performance, and predict equipment operating status and potential failures. Through sensors and data acquisition and analysis systems, it continuously monitors key indicators of lubricating oil such as temperature, pressure, cleanliness, moisture content, acid value, viscosity, and metal particle content, aiming to ensure stable equipment operation, extend the service life of lubricating oil and equipment, and reduce maintenance costs. However, because the lubricating oil monitoring housing is fixed to the outer wall of the oil pipe using mounting components, it can only fix oil pipes of a single diameter, limiting the applicable range of oil pipes for the online lubricating oil monitoring device. This prevents the device from monitoring lubricating oil in pipes of different diameters.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202321474169.1, application date 2023-12-26) provides a novel online lubricating oil monitoring device, including an upper shell, a lower shell, an upper fixing plate, a lower fixing plate, a connecting pipe, and a connecting cover. The lower shell is provided at the bottom of the upper shell, and the upper fixing plate is welded to both sides of the upper shell, and the lower fixing plate is welded to both sides of the lower shell. The positioning bolts, limiting blocks, anti-slip rubber rings, nuts, and fixing blocks facilitate the adjustment of the fixing length of the positioning bolts, allowing the upper and lower shells to be fitted onto oil pipes of different diameters. This enables the online lubricating oil monitoring device to be fixed on oil pipes of different diameters, improving the applicability of the online lubricating oil monitoring device. At the same time, the connecting groove, fixing rod, connecting frame, spring, positioning bolts, and limiting blocks facilitate the disassembly of the upper and lower shells, making the online lubricating oil monitoring device easy to assemble and disassemble.

[0004] When the device detects an abnormal lubricating oil flow, the DCS control system issues an interlocking shutdown command. The turbine protection trips to prevent dry running and equipment damage due to lack of lubricating oil. The flow switch uses a digital (DI) signal; an abnormal signal directly triggers the interlocking shutdown of the turbine. The turbine's shutdown and lack of vacuum directly impact production, causing paper breaks. The absence of an early warning system results in a passive production situation. During operation, the aforementioned device cannot provide early warning of the turbine's lubricating oil flow, leading to production line stagnation, affecting product delivery, increasing turbine maintenance costs, and shortening the turbine's lifespan. Utility Model Content

[0005] The purpose of this utility model is to provide a turbine lubricating oil flow monitoring and early warning system to solve the problem mentioned in the background art that it is impossible to realize early warning of turbine lubricating oil flow monitoring, which leads to production line shutdown, affects product delivery, increases turbine maintenance costs, and shortens the service life of the turbine.

[0016] (2) The turbine lubricating oil flow monitoring and early warning system enables the rapid installation of the flow monitor through the set locking block and support plate.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: By using the base 1, positioning plate 9, and support frame 3, the stability of the device during operation is improved, and the measurement accuracy of the flow monitor 6 is enhanced, ensuring measurement consistency. Figures 1-3 As shown: It includes a base 1, a turbine 2 is fixedly connected to the upper surface of the base 1, a support frame 3 is fixedly connected to the upper surface of the base 1, a fixing block 4 is fixedly connected to the upper front side of the support frame 3, and a positioning groove 5 is opened inside the fixing block 4. A flow monitor 6 is slidably connected to the front side of the fixing block 4, a fixing plate 8 is fixedly connected to the rear side of the flow monitor 6, and a positioning plate 9 is fixedly connected to the rear side of the fixing plate 8. The positioning plate 9 is slidably set on the surface of the positioning groove 5. A limit rod 17 is fixedly connected to the outer side of the fixing block 4, and a sliding column 18 is fixedly connected to the surface of the limit rod 17. A cleaning component 20 is slidably connected through the sliding column 18, and the cleaning component 20 is attached to the surface of the flow monitor 6.

[0029] The operator uses the positioning plate 9 on the rear side of the flow monitor 6 to cooperate with the positioning groove 5 inside the fixing block 4, so that the flow monitor 6 can be accurately positioned on the front side of the fixing block 4. Figure 2 and Figure 3 As shown, and to ensure that the flow monitor 6 does not easily shift during operation, the flow monitor 6 monitors the lubricating oil flow rate, such as... Figure 1As shown, when the flow monitor 6 detects an abnormal signal, the main equipment turbine 2 stops running. The analog signal value is transmitted back to the DCS control system via the three-way pressure measurement points at both ports. After acquiring the signal, the DCS system uses program logic to implement the abnormal flow signal and multi-level abnormal flow warning signals. The pressure transmitter processing module sets the early warning value for the flow monitoring system. When the warning value is triggered, the system automatically alarms to remind the operator, allowing for early analysis and judgment of whether the lubrication system is truly abnormal. This greatly improves system reliability and prevents unnecessary unplanned downtime caused by false detection of a single device leading to a chain reaction of equipment shutdowns. Simultaneously, the newly added flow monitoring early warning system provides sufficient time for fault handling and judgment. If it is a false alarm from an instrument, the early warning system can detect it and promptly de-interlock, preventing unplanned downtime caused by false alarms, saving unnecessary downtime and improving production efficiency.

[0030] In Example 2, unlike Example 1, the flow monitor 6 is quickly installed using the locking block 7, pull rod 13, and buffer spring 14. Figures 4-5 As shown: A locking block 7 is fixedly connected to the outside of the flow monitor 6, and the locking blocks 7 are symmetrically distributed about the center of the flow monitor 6. The surface of the locking block 7 is inclined at the end near the fixing block 4. A support plate 10 is fixedly connected to the outside of the fixing block 4, and the support plate 10 is symmetrically distributed about the center of the fixing block 4. A sliding rod 11 is fixedly connected to the inner wall of the support plate 10. A sliding plate 12 is slidably connected to the sliding rod 11. A pull rod 13 is fixedly connected to the surface of the sliding plate 12 near the end of the sliding rod 11. The pull rod 13 is slidably disposed inside the support plate 10. A buffer spring 14 is fixedly connected to the surface of the sliding plate 12 near the end of the pull rod 13. The other end of the buffer spring 14 is fixedly connected to the support plate 10. A connecting block 15 is fixedly connected to the front side of the sliding plate 12. The surface of the connecting block 15 is arc-shaped at the end near the flow monitor 6.

[0031] When the operator installs the flow monitor 6, the positioning plate 9 on the rear side of the flow monitor 6 engages with the positioning groove 5 inside the fixing block 4, allowing the flow monitor 6 to slide on the front side of the fixing block 4. Figure 1 As shown, when the engaging block 7 at the upper end of the flow monitor 6 contacts the connecting block 15, the flow monitor 6 pushes the connecting block 15, causing the buffer spring 14 at the upper end of the sliding plate 12 to retract towards the surface of the support plate 10. Simultaneously, the sliding plate 12 slides on the surface of the sliding rod 11. Figure 5 and Figure 6 As shown, the connecting block 15 slides on the surface of the locking block 7. When the positioning plate 9 is in contact with the inner wall of the fixing block 4, the buffer spring 14 pushes the connecting block 15, causing the connecting block 15 to slide on the inner wall of the locking block 7, as shown. Figure 5As shown, this allows the connecting block 15 to fit tightly against the inner wall of the locking block 7, enabling the installation of the flow monitor 6, reducing production losses caused by downtime, improving the overall efficiency of equipment maintenance, and ensuring that the equipment is in good operating condition.

[0032] In Example 3, unlike Example 2, the connecting plate 16, metal pull rope 19, and limiting rod 17 effectively reduce residual oil and dust on the surface of the flow monitor 6, ensuring that the monitor is always in good working condition. Figures 6-7 As shown: A connecting plate 16 is fixedly connected to one end of the pull rod 13 near the support plate 10, and one end of a metal pull rope 19 is fixedly connected to the lower surface of the connecting plate 16. The other end of the metal pull rope 19 is fixedly connected to a cleaning component 20. The limiting rods 17 are symmetrically distributed about the center of the fixing block 4, and the metal pull rope 19 is slidably arranged on the outside of the limiting rods 17.

[0033] The operator pulls the lever 13, causing it to slide inside the support plate 10, as... Figure 6 As shown, as the pull rod 13 slides inside the support plate 10, it drives the connecting plate 16 on the surface to slide at the upper end of the support plate 10. This causes the metal pull rope 19 at the lower end of the connecting plate 16 to pull the cleaning assembly 20 at the lower end, causing the cleaning assembly 20 to slide on the surface of the sliding column 18. Figure 7 As shown, the cleaning component 20 cleans the surface of the flow monitor 6, effectively reducing residual oil and dust on the surface, ensuring that the monitor is always in good working condition, enabling the flow monitor 6 to obtain accurate flow data, while extending the service life of the flow monitor 6 and improving the overall reliability of the equipment.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
