Description

Technical Field

[0001] This invention relates to the field of disassembly tools, specifically a multi-functional disc pump tool for vertical fire pumps and its usage method. Background Technology

[0002] Oilfield production environments contain many flammable and explosive locations and facilities, making fire suppression systems crucial equipment. Fire pumps are a vital component of these systems, serving as specialized pumps for delivering liquid extinguishing agents such as water. According to relevant fire safety regulations, fire pumps must always be in good working order and require regular maintenance to ensure smooth operation. The four existing vertical fire pumps in the Cainan operating area require manual rotation 2-3 times per week for trial runs to check for smooth pump shaft rotation, scraping noises from the pump and motor components, and the absence of jamming or leaks in any parts, ensuring the fire pumps are always in optimal working condition. However, the main problems currently existing are: 1. This type of pump has a compact overall structure and is vertically installed. The pump and motor share the same shaft. It consists of components such as pump body, impeller, pump cover, and mechanical seal. The pump shaft cover and pump body are integrally cast. The small clearance makes it impossible to use conventional tools to connect and rotate the pump shaft with a centrifugal pump coupling.

[0003] 2. When rotating the pumps, the motor fan cover must be removed. Each time, the removal and installation of the motor fan cover for 4 pumps takes about 70 minutes. The time spent on removing and installing the motor fan cover accounts for three-quarters of the total time of the pump rotation operation, making the weekly pump rotation work a large workload.

[0004] 3. When operating the current disc pump, it is necessary to rotate the motor fan blades to drive the motor rotor and the centrifugal pump shaft to achieve the purpose of disc pumping. This operation is prone to breaking the fan blades, and there are no fan blades of the same model to replace them, which increases production costs and workload.

[0005] In March 2024, through patent searches and the retrieval of related materials, three relevant patents or similar tools were found, but none of them were applicable to vertical fire pumps.

[0006] (1) High-efficiency and simple disc pump tool, patent publication number: CN214490440U Research content: To facilitate automatic, rapid and stable reinforcement of pump couplings, and to automatically control clamping force according to actual needs, thereby improving clamping stability, reducing the risk of slippage, and allowing for easy and labor-saving rotation of the coupling by using a handle lever after clamping, thus meeting usage requirements and facilitating operation.

[0007] (2) A disc pump tool for oil and gas production sites, patent publication number: CN216859617U Research content: To solve the problem that fire pumps and hot oil circulating pumps in natural gas processing stations of oil and gas production sites are not easy to clamp stably and quickly when rotating the coupling, which makes them prone to slippage during subsequent rotation.

[0008] (3) Disc pump tool, patent publication number: CN306033530S Research content: Used for pump body coupling operation (only applicable to pump body couplings of the corresponding size).

[0009] The above three pump control tools are all used on the coupling connecting the motor and the centrifugal pump to achieve the purpose of pump control, and are not suitable for vertical fire pumps. Summary of the Invention

[0010] This invention provides a multi-functional disc pump tool for vertical fire pumps and its usage method, overcoming the shortcomings of the prior art and effectively solving the problem that existing disc pump tools are not suitable for vertical fire pumps.

[0011] One of the technical solutions of the present invention is achieved through the following measures: a multi-functional disc pump tool for vertical fire pumps, including a sleeve head, a universal connector and a horizontal rod, wherein the upper end of the sleeve head and the lower end of the universal connector are fixed together, a through hole is provided at the upper end of the universal connector, and the middle part of the horizontal rod is fitted into the through hole.

[0012] The following are further optimizations and / or improvements to the above-mentioned technical solution: The upper end of the aforementioned sleeve head and the lower end of the universal connector are fixed together as a single unit.

[0013] The upper end of the aforementioned sleeve head and the lower end of the universal connector are fixed together by threads.

[0014] One end of the aforementioned horizontal bar is provided with a vertical bar, and a clamp corresponding to the vertical bar is provided on the horizontal bar between the vertical bar and the universal connector.

[0015] The top of the aforementioned universal connector is provided with a sleeve hole.

[0016] The second technical solution of the present invention is achieved through the following measures: a method for using a multi-functional disc pump tool for a vertical fire pump. First, a nut corresponding to the size of the sleeve head is welded to the center of the top of the motor rotor. Then, an operating hole is opened at the center point of the motor fan cover to insert the sleeve head. The position of the operating hole corresponds to the center of the motor rotor. During operation, the sleeve head is inserted into the motor fan cover and accurately locked onto the nut at the top of the motor rotor. The motor rotor is rotated left and right at will to complete the disc pump operation.

[0017] This invention has a reasonable and compact structure, is easy to use, and eliminates the phenomenon of not filling out false data due to laziness in pump inspection. On-site employees can regularly inspect the pump in accordance with the fire safety management regulations. In subsequent daily inspections, the timely pump inspection has promptly discovered multiple safety hazards such as water pump mechanical seal leakage and abnormal pressure, and repaired and replaced them, ensuring that the water pump can work normally in the event of a fire, ensuring that the fire protection facilities are always in good condition, achieving safe production, and also reducing the cost and workload of replacing fan blades. Attached Figure Description

[0018] Appendix Figure 1 This is a schematic diagram of the main structure of Embodiment 1 of the present invention.

[0019] Appendix Figure 2 This is a schematic diagram of the structure of Embodiment 2 of the present invention.

[0020] The codes in the attached diagram are as follows: 1 is the socket head, 2 is the universal connector, 3 is the horizontal bar, 4 is the motor fan guard, 5 is the motor rotor, 6 is the nut, 7 is the vertical bar, 8 is the caliper, and 9 is the socket hole. Detailed Implementation

[0021] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0022] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as front, back, top, bottom, left, right, etc. The positional relationships are determined based on the layout direction of the attached diagram in the instruction manual.

[0023] The present invention will be further described below with reference to embodiments and accompanying drawings: Example 1: As shown in the attached document Figure 1As shown, this multi-functional pump rotating tool for vertical fire pumps includes a sleeve head 1, a universal connector 2, and a horizontal rod 3. The upper end of the sleeve head 1 and the lower end of the universal connector 2 are fixed together. A through hole is provided at the upper end of the universal connector 2, and the middle part of the horizontal rod 3 is fitted into the through hole. The sleeve head 1 and the universal connector 2 are assembled into a long sleeve head. During operation, the sleeve head 1 is inserted into the motor fan cover 4 and accurately locked onto the nut 6 at the top of the motor rotor 5. Through the cooperation of the sleeve head 1 and the nut 6, the motor rotor 5 can be rotated left and right at will, completing the pump rotating operation. This eliminates the phenomenon of employees not rotating the pump on time and filling in false information due to laziness. Employees can rotate the pump regularly in accordance with the fire safety management regulations. In subsequent daily inspections, timely pump rotation promptly discovers multiple safety hazards such as water pump mechanical seal leakage and abnormal pressure, and repairs and replacements are carried out, ensuring that the water pump works normally during a fire, ensuring that fire-fighting facilities are always in good condition, achieving safe production, and reducing the cost and workload of replacing fan blades.

[0024] The following are further optimizations and / or improvements to the above-mentioned technical solution: As needed, the upper end of the sleeve head 1 and the lower end of the universal connector 2 are fixed together as a whole, and the upper end of the sleeve head 1 and the lower end of the universal connector 2 can be connected by welding.

[0025] As needed, the upper end of the socket head 1 and the lower end of the universal connector 2 are fixed together by threads, so that the socket head 1 can be used alone according to different scenarios.

[0026] As attached Figure 1 As shown, in order to complete the daily inspection of the fire pump room and open and close the valves in a timely manner, a vertical rod 7 is provided at one end of the horizontal rod 3. A clamp 8 corresponding to the vertical rod 7 is provided on the horizontal rod 3 between the vertical rod 7 and the universal connector 2. The vertical rod 7 and the clamp 8 form an F-wrench, which can facilitate the opening and closing of the valves.

[0027] To increase versatility, a sleeve hole 9 is provided on the top of the universal connector 2, which allows for the removal of a general nut.

[0028] Example 2: The method of using the multi-functional pump rotating tool for a vertical fire pump is as follows: First, weld a nut 6, corresponding to the size of the sleeve head 1, to the center of the top of the motor rotor 5. Then, open an operating hole at the center point of the motor fan cover 4, allowing the sleeve head 1 to be inserted. The operating hole should correspond to the center of the motor rotor 5. During operation, insert the sleeve head 1 into the motor fan cover 4 and accurately lock it onto the nut 6 at the top of the motor rotor 5. Rotate the motor rotor 5 left or right to complete the pump rotating operation. This eliminates the need to disassemble the motor fan cover 4 during routine pump rotating operations, reducing the cost and workload of replacing fan blades. It also allows staff to easily perform pump rotating operations, reducing the likelihood of staff failing to perform operations on time and filling out false records due to inconvenience, thus reducing safety hazards.

[0029] The following data is based on statistics of the single-person operation time of four fire pumps over four weeks: Analysis of the statistical table shows that: using a special tool for rotating four fire pumps, the average operation time for a single person to rotate the pump is... The time required for pump rotation was reduced to 2.8 minutes, a 96.2% reduction. During pump rotation, the pump shaft rotated flexibly, with uniform and smooth rotation without jamming or abnormal noise. There were no obstructions in the pipeline, and the medium did not solidify, achieving the goal of rapid pump rotation.

[0030] The above technical features constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
