Description

Technical Field

[0001] This invention relates to the field of fuel replenishment filtration technology, and more specifically, to a fuel replenishment filtration device for gas turbines. Background Technology

[0002] An internal combustion engine (also known as a fuel engine) is a power unit with an internal combustion engine at its core. It uses gasoline, diesel, kerosene, or other fuels and converts the heat energy released by fuel combustion into mechanical energy. It is widely used in many key fields such as automobiles, ships, generator sets, and construction machinery. Its core working principle is as follows: fuel mixes with air and enters the cylinder. After compression and ignition (gasoline engine) or compression ignition (diesel engine), combustion is completed. The high-temperature and high-pressure gas generated drives the piston to reciprocate. Then, through the crankshaft and connecting rod mechanism, the linear motion is converted into rotational motion, ultimately realizing power output.

[0003] During the long-term stable operation of a combustion engine, fuel replenishment is a fundamental prerequisite for its continuous operation, while fuel filtration is a core technical aspect that ensures fuel cleanliness, avoids equipment failure, and extends the overall service life of the engine. The efficient coordination of these two is a necessary condition for the stable power output of the combustion engine. However, during the entire process of fuel extraction, transportation, and storage, solid impurities such as mud, metal fragments, and dust inevitably mix in. At the same time, after long-term storage, fuel will also produce sticky deposits such as gum and asphalt. The core components of a combustion engine, such as fuel injectors, fuel pumps, and cylinder walls, are extremely precise. Once these impurities enter the fuel supply system with the fuel, they will cause a series of serious problems: fuel injector wear or blockage will lead to poor fuel atomization and incomplete combustion, resulting in reduced engine power and significantly increased fuel consumption; wear of precision components inside the fuel pump (such as plungers and delivery valves) will cause unstable fuel pressure fluctuations or even fuel supply interruption, which in severe cases can lead to fatal failures such as cylinder scoring and bearing seizure, greatly increasing equipment maintenance costs and downtime losses.

[0004] Existing gas turbine fuel replenishment filtration devices generally suffer from several technical defects: First, the filtration and pressurization functions are independent, requiring additional components such as filter pumps and booster pumps, resulting in complex structures, large sizes, and high energy consumption. Second, the displacement stroke of the pressurization component is fixed, making it impossible to dynamically adjust the fuel replenishment flow and pressure according to the differentiated needs of different gas turbine operating conditions (such as idling, low-speed cruising, high-speed heavy load, and start-up), leading to poor adaptability. Third, the short contact time between the oil and the filter element during filtration and insufficient scouring intensity easily cause filter element blockage, resulting in decreased filtration accuracy and unstable filtration flux. Fourth, some devices have poor sealing performance, allowing the oil to easily come into contact with the outside environment during filtration and pressurization, causing secondary contamination, or generating metal debris due to component friction, further affecting oil cleanliness. These problems severely restrict the overall efficiency and reliability of gas turbine fuel replenishment filtration, failing to meet the high-precision and high-stability operation requirements of fuel engines. Therefore, there is an urgent need for an integrated, adjustable, efficient, and clean gas turbine fuel replenishment filtration device. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fuel replenishment and filtration device for gas turbines, which aims to solve the problems mentioned in the background art.

[0006] The present invention provides the following technical solution: a gas turbine oil replenishment and filtration device, including a base, on which an oil replenishment and filtration assembly is disposed;

[0007] The oil replenishment and filtration assembly includes an oil replenishment cylinder disposed on the top of the base, an inner filter cylinder disposed in the middle of the oil replenishment cylinder, a gasket disposed on the top of the inner filter cylinder, and several oil delivery chambers being opened through the inner filter cylinder and the gasket, and a pressure boosting rod being movably connected in each of the oil delivery chambers, and several filter elements for filtration being disposed on the multiple pressure boosting rods, and the oil is extracted, filtered and pressurized and delivered by the up and down displacement of the pressure boosting rods and filter elements;

[0008] Each of the multiple booster rods has a hinged ball at its top, and a hinged sleeve is hinged to the outer side of each hinged ball. A pressure plate is fixedly and slidably connected to the top of the hinged sleeve. Arc-shaped support blocks are fixedly installed on both sides of the pressure plate. A protective cover is provided on the outer side of the pressure plate. The protective cover is located on the top of the oil replenishing cylinder, and the arc-shaped support blocks are rotatably connected to the protective cover, so that the pressure plate deflects along the connection between the arc-shaped support blocks and the protective cover to adjust the angle of the pressure plate. When the inner filter cylinder rotates, it drives the booster rods to rotate and move. The booster rods move up and down inside the inner filter cylinder, so that the booster rods and filter elements move upward to extract and filter the oil, and the booster rods and filter elements move downward to pressurize the oil.

[0009] Furthermore, the oil replenishment filter assembly also includes a horizontal bar placed inside the protective cover. The horizontal bar is slidably connected to the protective cover. A sliding column is fixedly provided on the outer side of the horizontal bar. A handle is rotatably connected to one side of the protective cover. The handle is threadedly connected to the horizontal bar. Rotating the handle drives the horizontal bar to move laterally inside the protective cover. A mounting plate is provided at the top of the horizontal bar. The mounting plate is embedded in the top of the inner cavity of the protective cover. A slide is rotatably connected to the bottom of the mounting plate. The sliding column extends to the middle of the slide and is slidably connected to the slide. The pressure plate is hinged to the horizontal bar. The lateral movement of the horizontal bar drives the pressure plate to rotate axially along the connection between the arc support block and the protective cover, which is used to adjust the tilt angle of the pressure plate. The sliding cooperation between the slide and the sliding column is used to guide the lateral movement of the horizontal bar.

[0010] Furthermore, the oil replenishment and filtration assembly also includes a sealing disc disposed at the bottom of the inner liner filter cartridge. The sealing disc has several oil passage holes, each located directly below a corresponding oil delivery chamber. An oil inlet is located on one side of the bottom of the base, and an oil outlet is located on the other side of the bottom of the base. Both the oil inlet and outlet are located at the bottom of the sealing disc. Oil is delivered to the inner liner filter cartridge through the oil inlet and oil passage holes, where it is filtered and pressurized by the booster rod and filter element. A first guide port and a second guide port are respectively provided on both sides of the bottom of the inner wall of the oil replenishment cartridge. The first guide port is located at the top of the oil inlet, and the second guide port is located at the top of the oil outlet. The sealing disc is located on the upper surface of the first and second guide ports, so that when each oil replenishing cylinder and the sealing disc rotate, each oil delivery chamber and oil passage hole is connected to the first and second guide ports one by one. In conjunction with the pressure booster and the vertical displacement of the filter element, the oil is extracted, filtered, and pressurized for delivery. A motor is provided at the bottom of the base, and a rotating shaft is provided at the output end of the motor. The rotating shaft is located in the middle of the inner filter cylinder, and the inner filter cylinder is rotated by the motor.

[0011] The technical effects and advantages of this invention are as follows:

[0012] 1. This invention integrates filtration, pressurization, and conveying functions into the same oil replenishment filter assembly. The motor drives the rotating shaft to rotate the inner filter cartridge, simultaneously providing rotational power to multiple pressurizing rods. This allows the pressurizing rods to complete up-down and back-down movement during rotation, eliminating the need for separate filter pumps, pressurizing pumps, and other components. The integrated design greatly simplifies the device.

[0013] 2. Based on the aforementioned integrated structure, this invention achieves precise control of the booster rod displacement stroke through pressure plate angle adjustment, perfectly adapting to the differentiated needs of various gas turbine operating conditions. The larger the pressure plate tilt angle, the greater the booster rod stroke, resulting in more oil being drawn in and squeezed in a single operation, and a higher boost pressure; conversely, the smaller the stroke, the lower the boost pressure. Combined with the rotational speed adjustment of the inner filter cartridge, dynamic matching of flow rate and pressure can be achieved. This adjustability solves the shortcomings of existing devices that are only adaptable to a single operating condition and inefficient across multiple operating conditions, giving the device adaptability and providing a basis for improving filtration efficiency and boost pressure stability.

[0014] 3. Based on the integrated structure and adjustable stroke function, this invention achieves synergistic effect of filtration and pressurization through the reciprocating motion of the pressure booster rod. When the inner filter cartridge rotates, the pressure booster rod rotates synchronously and moves up and down. During upward movement, a negative pressure is created in the oil delivery chamber, drawing oil through the oil passage and the first guide port. The oil fully contacts and slowly permeates the filter element surface. During downward movement, the volume of the oil delivery chamber is compressed, pressurizing the filtered oil and allowing it to be output at a stable pressure through the second guide port and the oil outlet. Simultaneously, the reciprocating motion of the pressure booster rod creates alternating suction and compression, resulting in pressure fluctuations between the inner and outer sides of the filter element. This effectively prevents impurities from accumulating and clogging the filter element surface, maintaining a stable filtration throughput.

[0015] 4. This invention can further optimize the filtration effect by adjusting the stroke of the booster rod: for oils with high impurity content, increasing the stroke enhances the scouring intensity and strengthens the ability to remove stubborn impurities; for oils with high cleanliness, decreasing the stroke improves the conveying efficiency while ensuring the filtration effect. Compared with the prior art, this invention improves the oil filtration accuracy and has a low oil pressure control error, achieving a simultaneous improvement in filtration accuracy and boosting stability.

[0016] In summary, this invention relies on the aforementioned filtration and pressurization synergy mechanism. The device's oil replenishment cylinder and protective cover form a closed cavity. The reciprocating motion of the pressurizing rod and the rotation of the inner filter cartridge both occur in a closed environment, effectively preventing the oil from contacting external air and impurities. The sealing disc fits tightly against the inner wall of the oil replenishment cylinder, and the oil passage hole precisely corresponds to the oil delivery chamber, preventing oil leakage. These sealing and protective designs, combined with the filtration function, provide double protection for the cleanliness of the output oil, effectively preventing clogging of precision components such as the gas turbine injectors and oil pumps, reducing engine malfunctions caused by oil contamination, and extending the service life of the gas turbine.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Example 1

[0028] This embodiment discloses a gas turbine fuel replenishment filtration device, which aims to solve the technical problems of low filtration efficiency, poor pressurization effect, and inability to achieve continuous and stable filtration delivery in existing gas turbine fuel replenishment filtration devices.

[0029] Specifically, the gas turbine oil replenishment and filtration device includes a base 1, which is cast entirely from a high-strength alloy material and has anti-slip and shock-absorbing pads on the bottom to ensure the stability of the device during operation. The base 1 is equipped with a complete oil replenishment and filtration assembly, which is the core structure for realizing oil filtration, pressurization, and transportation.

[0030] The main body of the oil replenishment filter assembly is the oil replenishment cylinder 2, which is fixedly installed on the top of the base 1. Its inner wall is precision polished to reduce oil flow resistance. A liner filter cylinder 3 is coaxially arranged in the middle of the oil replenishment cylinder 2. The liner filter cylinder 3 adopts an integrated structure of stainless steel filter mesh and supporting frame, ensuring both structural strength and preliminary impurity filtration. A gasket 4 is bolted to the top of the liner filter cylinder 3, and the gasket 4 fits tightly against the top surface of the liner filter cylinder 3. Several oil delivery chambers 5 are correspondingly perforated on both, arranged in a circular array. The inner diameter of each oil delivery chamber 5 matches the outer diameter of the booster rod 6.

[0031] Each oil delivery chamber 5 is movably connected to a pressure booster rod 6. Several filter elements 7 are evenly arranged along the length of the outer wall of the pressure booster rod 6. The filter elements 7 adopt a multi-layer glass fiber and activated carbon composite structure, which can effectively remove impurities such as mud, metal fragments, and colloids from the oil. The pressure booster rod 6 can move up and down along the axial direction of the oil delivery chamber 5. Through its up-and-down movement, it achieves the dual functions of oil extraction and filtration as well as pressure boosting and delivery. When the filter elements 7 reciprocate with the pressure booster rod 6, pressure pulsations are formed within the oil delivery chamber 5 to strip away and trap impurities.

[0032] like Figure 5 , Figure 7As shown, each of the multiple booster rods 6 has a hinged ball 8 at its top. The hinged ball 8 is made of wear-resistant ceramic material, and a hinged sleeve 9 is fitted to its outer side. A pressure plate 12 is fixedly and slidably connected to the top of the hinged sleeve 9. The pressure plate 12 is made of lightweight aluminum alloy, and arc support blocks 11 are integrally formed on both sides. A protective cover 10 is provided on the outer side of the pressure plate 12. The arc-shaped surface of the arc support block 11 fits against the inner wall of the protective cover 10. The protective cover 10 is detachably connected to the top of the oil filling cylinder 2 by a buckle, which facilitates later maintenance and repair. The arc support block 11 and the inner wall of the protective cover 10 are rotatably connected by a pivot pin, so that the pressure plate 12 can flexibly deflect along the connection between the arc support block 11 and the protective cover 10, thereby adjusting the tilt angle of the pressure plate 12. When the inner filter cylinder 3 rotates, it drives each pressure rod 6 to rotate and move synchronously. With the angle adjustment of the pressure plate 12, the pressure rod 6 moves up and down inside the inner filter cylinder 3. When the pressure rod 6 and the filter element 7 move upward, the oil is drawn out using the principle of negative pressure and filtered through the filter element 7. When the pressure rod 6 and the filter element 7 move downward, pressure is applied to the filtered oil to achieve pressurized delivery. Example 2

[0033] Based on Example 1, this embodiment, for example Figure 2 , Figure 6 As shown, the oil replenishment filter assembly also includes a horizontal bar 13 placed inside the protective cover 10. The horizontal bar 13 has a cylindrical structure, and its two ends are slidably connected to the inner wall of the protective cover 10 through sliding sleeves. The sliding sleeves are made of polytetrafluoroethylene to reduce sliding friction. A sliding column 14 is welded and fixed to the outside of the horizontal bar 13, and the sliding column 14 is set perpendicular to the horizontal bar 13. One end of the protective cover 10 is rotatably connected to a handle 25 through a bearing. The end of the handle 25 is provided with an anti-slip knob, and the middle is provided with an external thread, which is threadedly connected to the threaded hole at the end of the horizontal bar 13. By rotating the handle 25, the horizontal bar 13 can be driven to move horizontally inside the protective cover 10.

[0034] A mounting plate 15 is provided at the top of the crossbar 13. The mounting plate 15 is fixed to the top of the inner cavity of the protective cover 10 by screws. The bottom of the mounting plate 15 is rotatably connected to the slide 16 by a pivot pin. The slide 16 has a U-shaped structure and a groove inside that matches the sliding column 14. The end of the sliding column 14 away from the crossbar 13 extends into the middle groove of the slide 16 and is slidably connected to the groove. The middle part of the pressure plate 12 is hinged to the crossbar 13 by a hinge seat. When the crossbar 13 moves laterally, it will drive the pressure plate 12 to rotate axially along the connection between the arc support block 11 and the protective cover 10, thereby precisely adjusting the tilt angle of the pressure plate 12 to meet the fluctuation range requirements of the pressure bar 6 under different working conditions. At the same time, the sliding cooperation between the slide 16 and the sliding column 14 can guide and limit the lateral movement of the crossbar 13, preventing the crossbar 13 from deviating and causing the pressure plate 12 to get stuck.

[0035] like Figure 3 , Figure 7 , Figure 8 As shown, a sealing disc 17 is provided at the bottom of the inner filter cartridge 3. The sealing disc 17 is made of nitrile rubber, which has good sealing performance and oil resistance. Its edge is tightly fitted to the inner wall of the oil supply cylinder 2 through a sealing ring to prevent oil leakage. Several oil passage holes 18 are provided through the sealing disc 17. The number of oil passage holes 18 is the same as the number of oil delivery chambers 5, and each oil passage hole 18 is located directly below the corresponding oil delivery chamber 5 to ensure that the oil can accurately enter the oil delivery chamber 5.

[0036] An oil inlet 19 is located on one side of the bottom of the base 1, and an oil outlet 20 is located on the other side. Both the oil inlet 19 and the oil outlet 20 use standard pipe thread interfaces for easy connection to the gas turbine's oil supply pipeline. Both the oil inlet 19 and the oil outlet 20 are located at the bottom of the sealing disc 17 and are connected to the oil passage inside the base 1. A first guide port 21 and a second guide port 22 are respectively opened on both sides of the bottom of the inner wall of the oil replenishing cylinder 2. The first guide port 21 is located directly above the oil inlet 19, and the second guide port 22 is located directly above the oil outlet 20. The sealing disc 17 is tightly fitted against the upper surfaces of the first guide port 21 and the second guide port 22, forming a sealed fit. When the oil replenishing cylinder 2 and the sealing disc 17 rotate, each oil delivery chamber 5 and the oil passage hole 18 alternately connects to the first guide port 21 and the second guide port 22, realizing continuous oil input and output.

[0037] A motor 23, a servo motor of model MSME-5AZG1, is bolted to the center of the bottom of the base 1. The output of the motor 23 is connected to a rotating shaft 24 via a coupling. The rotating shaft 24 extends vertically upwards, passing through the center of the base 1 and the sealing disc 17, and is fixedly connected to the center of the inner filter cartridge 3. The rotating shaft 24, driven by the motor 23, rotates synchronously, providing power for the operation of the entire oil replenishment filtration assembly.

[0038] The specific working principle is as follows:

[0039] Before starting the device, first connect the oil to be filtered into the oil channel of the base 1 through the oil inlet 19, and at the same time check the sealing of each connection to ensure there is no leakage.

[0040] Start the motor 23, which drives the rotating shaft 24 to rotate, thereby driving the inner filter cartridge 3 to rotate at a constant speed inside the oil replenishment cylinder 2.

[0041] During the rotation of the inner filter cartridge 3, the operator can adjust the lateral movement distance of the crossbar 13 by rotating the handle 25. The crossbar 13 moves smoothly under the guidance of the sliding column 14 and the slide frame 16, thereby driving the pressure plate 12 to deflect along the connection between the arc support block 11 and the protective cover 10, and adjusting it to a suitable tilt angle.

[0042] As the inner filter cartridge 3 rotates, the oil passage holes 18 on the sealing disc 17 connect one by one with the first guide port 21 at the bottom of the oil replenishment cylinder 2. At this time, the oil in the oil inlet 19 enters the corresponding oil delivery chamber 5 of the inner filter cartridge 3 through the first guide port 21 and the oil passage holes 18 in sequence.

[0043] Under the combined action of the rotation of the inner filter cylinder 3 and the angular constraint of the pressure plate 12, the booster rod 6 moves up and down along the oil delivery chamber 5: when the booster rod 6 moves upward, a negative pressure is formed in the oil delivery chamber 5, which draws in the oil and filters it through the filter element 7. The multi-layer composite structure of the filter element 7 effectively traps impurities in the oil; when the booster rod 6 moves downward, it applies pressure to the filtered oil to achieve pressurization.

[0044] In the above steps, the requirements for fuel replenishment flow rate, pressure, and filtration efficiency vary significantly under different operating conditions of the gas turbine, such as idling, low-speed cruising, high-speed heavy load, and startup.

[0045] For example, when a gas turbine starts, it requires a low flow rate but stable oil pressure to prevent poor atomization of the fuel injector due to oil pressure fluctuations; at high speeds and heavy loads, it requires a large flow rate and high pressure of clean oil to ensure power output.

[0046] In this design, the horizontal bar 13 is moved laterally by rotating the handle 25. Figure 6 As shown, the crossbar 13 drives the pressure plate 12 to rotate axially along the connection between the arc support block 11 and the protective cover 10, which can precisely adjust the tilt angle of the pressure plate 12. The greater the tilt angle of the pressure plate 12, the stronger the constraint effect of the pressure bar 6 on the hinge ball 8 and the hinge sleeve 9, and the greater the stroke of the vertical displacement; conversely, the smaller the stroke.

[0047] The rotational power of the inner filter cartridge 3 is achieved by the motor 23 driving the rotating shaft 24, such as... Figure 5 As shown, the reciprocating frequency and stroke of the booster rod 6 can be adjusted independently to achieve dynamic matching of flow rate, pressure and filtration accuracy, adapt to the full operating conditions of the gas turbine, and solve the defects of existing fixed stroke filtration devices that are only adaptable to a single operating condition and inefficient in multiple operating conditions.

[0048] When the inner filter cartridge 3 rotates, the pressure rod 6 rotates synchronously with it and moves up and down back to its original position. Figure 7 , Figure 8 As shown, on the one hand, the residence time of the oil in the oil delivery chamber 5 is extended, allowing the filter element 7 to have more time to trap impurities; on the other hand, the up-and-down reciprocating motion of the booster rod 6 forms an alternating action of suction and compression, and the oil forms a pressure difference fluctuation on the inner and outer sides of the filter element 7, which can effectively prevent impurities from accumulating and clogging on the surface of the filter element 7 and maintain the filtration throughput of the filter element 7.

[0049] Furthermore, by adjusting the displacement stroke of the booster rod 6 through the pressure plate 12, this effect can be further optimized: for oils with high impurity content, the stroke can be increased to enhance the suction and squeezing strength, thereby strengthening the filter element 7's ability to peel off and filter stubborn impurities; for oils with high cleanliness, the stroke can be reduced to improve conveying efficiency while ensuring filtration effect.

[0050] When the oil delivery chamber 5, which contains filtered and pressurized oil, rotates with the inner filter cartridge 3 to the position corresponding to the second guide port 22, the oil passage hole 18 connects with the second guide port 22. The pressurized clean oil passes through the oil passage hole 18 and the second guide port 22 in sequence and enters the oil outlet channel of the base 1. Finally, it is output from the oil outlet pipe 20 to the oil supply system of the gas turbine, completing one filtration and pressurization cycle.

[0051] The inner filter cartridge 3 rotates continuously, and each oil delivery chamber 5 sequentially completes the oil suction, filtration, pressurization and oil discharge processes to achieve continuous and stable oil filtration and delivery.

[0052] In the above technical solution, the up-and-down reciprocating movement of the booster rod 6 is the core of achieving oil pressurization. Figure 2 , Figure 4 As shown: When the displacement is upward, a negative pressure is formed in the oil delivery chamber 5, and the oil is drawn from the oil inlet 19 through the oil passage 18 and the first guide port 21; when the displacement is downward, the volume of the oil delivery chamber 5 is compressed, and the oil is output through the second guide port 22 and the oil outlet 20 after being pressurized, thus completing the pressurized delivery.

[0053] The pressure plate 12 adjusts the displacement stroke of the booster rod 6, which can directly control the amount of oil and pressure of a single boost: when the stroke increases, the amount of oil sucked and squeezed in a single operation increases, and the boosting amplitude increases; when the stroke decreases, the boosting amplitude decreases. Combined with the adjustment of the rotation speed of the inner filter cartridge 3, precise control of oil pressure can be achieved, solving the problems of non-adjustable boosting pressure and large fluctuations in existing devices.

[0054] Simultaneously, the rotation of the inner filter cartridge 3 drives multiple pressure boosting rods 6 to alternately move back and forth, coordinating with the oil passage 18 on the sealing disc 17 to circulate with the first guide port 21 and the second guide port 22, such as... Figure 3 As shown, this enables continuous pressurized delivery of oil without interruption, ensuring the stability of the gas turbine oil supply system.

[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
