Description

Technical Field

[0001] This utility model belongs to the technical field of circulating pumps in gas-fired power plants, and specifically relates to an assembly support for a circulating pump in a gas-fired power plant. Background Technology

[0002] A gas-fired power plant circulating pump is a device that uses mechanical energy to transport cooling water to the condenser, thereby facilitating steam condensation, maintaining the turbine vacuum environment, and ensuring the unit's thermal efficiency. In practical applications, the circulating pump requires an external drive motor. The motor's output shaft drives the impeller shaft to rotate, controlling the pump's operation.

[0003] Meanwhile, in existing technologies, circulating pumps in gas-fired power plants are mainly bolted to the ground in the operating area. However, since a transmission connection is required between the drive motor and the circulating pump, the axis of the circulating pump impeller shaft and the output shaft of the drive motor must be aligned to ensure the stability of the transmission connection. This means that during the assembly and commissioning process, the height of the circulating pump needs to be adjusted multiple times by placing shims or other support components at the bottom of the pump. This method is not only cumbersome and complex, but also has poor effect on adjusting the height of the circulating pump, resulting in low efficiency in disassembly, assembly, and maintenance.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a support for the assembly of a circulating pump in a gas-fired power plant.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0006] The purpose of this utility model is to provide a support for the assembly of a circulating pump in a gas-fired power plant, which simplifies the process of adjusting the height of the circulating pump and improves the efficiency of disassembly, assembly and maintenance of the circulating pump.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows: A circulating pump assembly support for a gas-fired power plant includes: a pump body, a pump body mounting base, a split assembly assembly, and a support and control assembly.

[0008] A pump body mounting base is fixedly installed below the pump body. A split-type assembly is mounted below the pump body. This assembly includes an upper support, a lower support, multiple threaded support rods, and multiple sets of fixing nuts. The upper support is fixedly installed at the bottom of the pump body mounting base. The lower support is positioned below the upper support. Multiple threaded support rods are symmetrically fixed around the lower support, and the lower support slides against the threaded support rods. Multiple sets of fixing nuts are threaded in pairs above the threaded support rods, providing support and fixation for the upper support.

[0009] The support control assembly is assembled between the upper support and the lower support. The support control assembly includes an adjusting shaft and a pair of support sliders. The pair of support sliders are both sleeved on the outside of the adjusting shaft and are threadedly connected to the adjusting shaft.

[0010] In one or more embodiments of this utility model, an inlet pipe and an outlet pipe are fixedly connected to both sides of the pump body, respectively, and the inlet pipe connects to the cooling water inlet pipe and the outlet pipe. The pump body mounting base and the upper support are bolted together. The pump body mounting base is fixedly assembled on the upper support by bolting.

[0011] In one or more embodiments of this utility model, the upper support includes an upper support base plate, a pair of upper side plates, and a pair of upper support frames. The upper support base plate is disposed below the pump body, and the pair of upper side plates are symmetrically fixedly assembled on both sides of the upper support base plate. The pump body is assembled and fixed by the cooperation of the upper support base plate and the upper side plates.

[0012] In one or more embodiments of this utility model, a pair of upper support frames are fixedly assembled on both sides of the upper support base plate opposite to the upper side plate, and the upper support frames serve to assemble and fix the upper positioning ear plates. Each pair of upper support frames has a pair of upper positioning ear plates fixedly connected to its side opposite to the upper support base plate. The upper positioning ear plates serve to guide the threaded support rod during assembly. Simultaneously, the upper support can be assembled and limited by supporting and positioning the upper positioning ear plates with fixing nuts.

[0013] In one or more embodiments of this utility model, the upper positioning ear plate is slidably sleeved on the outside of the threaded support rod, and the two fixing nuts are respectively arranged on both sides of the upper positioning ear plate. The upper positioning ear plate is supported and limited by a pair of fixing nuts, thereby playing a role in limiting the assembly of the upper support.

[0014] In one or more embodiments of this utility model, the lower support includes a lower support base plate, a pair of lower side plates, and a pair of lower support frames. The lower support base plate is arranged directly below the upper support base plate, and the pair of lower side plates are symmetrically fixedly installed on both sides of the lower support base plate.

[0015] In one or more embodiments of this utility model, a pair of lower support frames are fixedly connected to the two sides of the lower support base plate opposite to the lower side plate.

[0016] In one or more embodiments of this utility model, the adjusting shaft has external threads with opposite helical directions on both sides, and each pair of support sliders has internal threads with the same thread direction. The external and internal threads form a threaded pair. Through the engagement of the internal threads of the support sliders and the external threads of the adjusting shaft, the pair of support sliders can move in opposite directions under the action of the internal and external threads by driving the adjusting shaft to rotate. Therefore, the height of the upper support can be adjusted by adjusting the distance between the pair of support sliders.

[0017] In one or more embodiments of this utility model, a rotating handle is fixedly connected to one end of the adjusting shaft. The adjusting shaft is driven to rotate by controlling the rotation of the rotating handle. An anti-detachment block is fixedly connected to the end of the adjusting shaft away from the rotating handle.

[0023] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0024] like Figures 1 to 5As shown, in one embodiment of this utility model, the circulating pump assembly support for a gas-fired power plant includes: a pump body 1, a pump body fixing seat 101, a split assembly assembly 2, and a support control assembly 3. In practical applications, the pump body 1 can be assembled and fixed by supporting and fixing the pump body fixing seat 101 using the split assembly assembly 2. Simultaneously, the height of the pump body 1 can be adjusted by adjusting the height of the split assembly assembly 2 using the support control assembly 3, so that the impeller shaft inside the pump body 1 coincides with the axis of the motor output shaft.

[0025] like Figure 1 As shown, a pump body mounting base 101 is fixedly mounted on the lower part of the pump body 1. The pump body 1 is installed and fixed by assembling and fixing the pump body mounting base 101.

[0026] like Figure 1 As shown, an inlet pipe 102 and an outlet pipe 103 are fixedly connected to both sides of the pump body 1, respectively, and the inlet and outlet of cooling water are connected and connected through the inlet pipe 102. The pump body mounting base 101 and the upper support 201 are bolted together. The pump body mounting base 101 is fixedly assembled on the upper support 201 by bolting.

[0027] like Figure 1 As shown, the split assembly 2 is mounted below the pump body 1. The split assembly 2 includes an upper support 201, a lower support 202, multiple threaded support rods 203, and multiple sets of fixing nuts 204. The upper support 201 is fixedly mounted to the bottom of the pump body mounting base 101, and the upper support 201 provides support and fixation for the pump body mounting base 101. Simultaneously, the height of the pump body 1 can be adjusted by adjusting the horizontal height of the upper support 201.

[0028] like Figure 1 As shown, the upper support 201 includes an upper support base plate 2011, a pair of upper side plates 2012, and a pair of upper support frames 2013. The upper support base plate 2011 is located below the pump body 1, and the pair of upper side plates 2012 are symmetrically fixedly assembled on both sides of the upper support base plate 2011. The pump body 1 is assembled and fixed through the cooperation of the upper support base plate 2011 and the upper side plates 2012.

[0029] like Figure 1 As shown, a pair of upper support frames 2013 are fixedly assembled on both sides of the upper support base plate 2011 opposite to the upper side plate 2012. The upper support frames 2013 serve to assemble and fix the upper positioning ear plates 205. A pair of upper positioning ear plates 205 are fixedly connected to each side of the pair of upper support frames 2013 opposite to the upper support base plate 2011. The upper positioning ear plates 205 serve to guide the assembly of the threaded support rod 203. Simultaneously, the upper support 201 can be assembled and limited by supporting and positioning the upper positioning ear plates 205 with fixing nuts 204.

[0030] like Figure 1 As shown, the upper positioning ear plate 205 is slidably sleeved on the outside of the threaded support rod 203, and two fixing nuts 204 are respectively arranged on both sides of the upper positioning ear plate 205. The upper positioning ear plate 205 is supported and limited by a pair of fixing nuts 204, thereby playing a role in limiting the assembly of the upper support 201.

[0031] like Figures 1 to 2 As shown, the lower support 202 is positioned below the upper support 201. The split assembly component 2 is fixed as a whole by assembling and fixing the lower support 202.

[0032] like Figures 1 to 2 As shown, the lower support 202 includes a lower support base plate 2021, a pair of lower side plates 2022, and a pair of lower support frames 2023. The lower support base plate 2021 is located directly below the upper support base plate 2011, and the pair of lower side plates 2022 are symmetrically fixed on both sides of the lower support base plate 2021.

[0033] like Figures 1 to 2 As shown, a pair of lower support frames 2023 are fixedly connected to the lower support base plate 2021 on both sides away from the lower side plate 2022. The lower support frames 2023 serve to connect and fix the lower positioning ear plates 206 and the assembly ear plates 207. A pair of lower positioning ear plates 206 and a pair of assembly ear plates 207 are fixedly connected to the side of each pair of lower support frames 2023 away from the lower support base plate 2021, and the bottom ends of multiple threaded support rods 203 are fixedly connected to the lower positioning ear plates 206. The lower positioning ear plates 206 provide support and fixation for the threaded support rods 203. The lower support 202 can be assembled in the working area by assembling and fixing the assembly ear plates 207.

[0034] like Figures 1 to 2 As shown, multiple threaded support rods 203 are symmetrically fixed around the lower support 202, and the lower support 202 and the multiple threaded support rods 203 are in sliding engagement. Multiple sets of fixing nuts 204 are threadedly fitted in pairs above the multiple threaded support rods 203, and the multiple sets of fixing nuts 204 are used to support and fix the upper support 201. The cooperation between the threaded support rods 203 and the fixing nuts 204 provides overall support and limitation for the upper support 201, ensuring the stability of the upper support 201 in supporting and fixing the pump body 1.

[0035] like Figures 3 to 4As shown, the support control assembly 3 is assembled between the upper support 201 and the lower support 202. The support control assembly 3 includes an adjusting shaft 301 and a pair of support sliders 302. The pair of support sliders 302 are both sleeved on the outside of the adjusting shaft 301 and are threadedly connected to the adjusting shaft 301. The adjusting shaft 301 provides support, limit, and movement control for the pair of support sliders 302.

[0036] Specifically, the adjusting shaft 301 has external threads with opposite helical directions on both sides, and each pair of support sliders 302 has internal threads with the same thread direction. The external and internal threads form a threaded pair. Through the cooperation between the internal threads of the support sliders 302 and the external threads of the adjusting shaft 301, the pair of support sliders 302 can move in opposite directions under the action of the internal and external threads by driving the adjusting shaft 301 to rotate. Thus, the height of the upper support 201 can be adjusted by adjusting the distance between the pair of support sliders 302.

[0037] like Figures 3 to 4 As shown, a rotating handle 303 is fixedly connected to one end of the adjusting shaft 301. The adjusting shaft 301 is rotated by controlling the rotation of the rotating handle 303. An anti-detachment block 304 is fixedly connected to the end of the adjusting shaft 301 away from the rotating handle 303. The anti-detachment block 304 serves to limit the detachment of the supporting slider 302.

[0038] like Figures 3 to 4 As shown, a pair of support sliders 302 are equipped with connecting components on both sides. The connecting components are used to connect the support sliders 302 with the upper support 201 and the lower support 202.

[0039] like Figures 3 to 4 As shown, the connecting assembly includes a connecting support 305, a supporting support 306, and a connecting rod 307. The connecting support 305 is fixedly connected to the outer side of the supporting slider 302. The supporting support 306 is fixedly connected to the side of the upper support 201 or the lower support 202. The two ends of the connecting rod 307 are hinged to the connecting support 305 and the supporting support 306, respectively. Through the cooperation of the connecting support 305, the supporting support 306, and the connecting rod 307, the supporting slider 302 can support and limit the upper support 201 and the lower support 202.

[0040] In practical use, the pump body mounting base 101 can be fixedly assembled onto the upper support 201 using bolts, and the lower support 202 can be assembled onto the ground by bolting the mounting lug 207. Subsequently, the fixing nut 204 on the upper positioning lug 205 can be removed.

[0041] Then, by controlling the rotation of the rotary handle 303, a pair of support sliders 302 can move in opposite directions under the action of the internal and external threads. Through the cooperation of the support sliders 302, connecting support 305, support support 306 and connecting rod 307, when the distance between the pair of support sliders 302 decreases, the connecting rod 307 can lift and support the upper support 201. By controlling the movement of the support sliders 302, the horizontal height of the pump body 1 can be adjusted, thereby simplifying the process of adjusting the height of the pump body 1.

[0042] After adjustment, the upper support 201 can be further supported and fixed by using the fixing nut 204 to support and position the upper positioning ear plate 205.
