Description

Technical Field

[0001] This utility model relates to the field of synchronous rotary mixed pump technology, and in particular to a parallel synchronous rotary mixed pump. Background Technology

[0002] Parallel synchronous rotary mixed pumps are high-efficiency fluid machinery suitable for transporting multiphase media, and are widely used in petrochemical, oil and gas extraction, chemical production and other fields.

[0003] However, the existing equipment has the following shortcomings: the placement frame of the existing equipment, as the supporting component of the pump body, has a fixed height of a single specification. In actual installation operations, due to differences in the laying height of pipelines under different working conditions, or due to insufficient flatness of the site, it is necessary to fine-tune the height of the placement frame to ensure accurate docking between the pump body and the pipeline connection. However, due to the lack of convenient height adjustment function, operators cannot quickly adjust the height of the placement frame and can only try to adapt it by adding extra shims and replacing support components. This adjustment method is not only time-consuming and laborious, but also makes it difficult to guarantee the accuracy of height adjustment. It is very easy to cause obvious misalignment and uneven gaps between the connection between the pump body and the pipeline, which increases the difficulty of installing the pipeline and the pump body, prolongs the construction period, and affects the accurate installation of the equipment.

[0004] Therefore, we propose a parallel synchronous rotary mixed pump to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, which has a fixed equipment height, makes it difficult to quickly adjust the height of the placement frame, and makes it difficult to accurately install the pump body and pipeline. Therefore, a parallel synchronous rotary mixed pump is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a parallel synchronous rotary mixed pump, comprising a placement frame, a power motor, a coupling, a pump body, and an adjusting device. The power motor is fixedly connected to the upper surface of the placement frame, the coupling is fixedly connected to the upper surface of the placement frame, and the pump body is fixedly connected to the upper surface of the placement frame. The output end of the power motor is installed at one end of the coupling, and one end of the pump body is installed at the end of the coupling away from the power motor. The adjusting device is installed on the lower surface of the placement frame and includes a support column and a contact block. The support column is installed inside the placement frame, and the contact block is fixedly connected to the lower end of the support column. A connecting block is fixedly connected to the upper end of the support column, and a threaded rod is fixedly connected to the upper end of the connecting block. A limit block is fixedly connected to the upper end of the threaded rod, and a gear is threadedly connected to the surface of the threaded rod. An auxiliary component is installed on the surface of the gear. The auxiliary component includes a first limit ring and a second limit ring. The first limit ring is fitted onto the upper surface of the gear, and the second limit ring is fitted onto the lower surface of the gear. The first limit ring and the second limit ring are fixedly connected by a mounting bracket, which is fixedly connected inside the placement frame.

[0007] Furthermore, the first limiting ring and the second limiting ring are sleeved and connected to the surface of the threaded rod. By setting the first limiting ring and the second limiting ring, the gear can be limited, reducing the possibility that the gear may move up and down during use, making it difficult for the gear to drive the threaded rod smoothly.

[0008] Furthermore, a worm gear is meshed with the side of the gear to facilitate the rotation of the drive gear.

[0009] Furthermore, rotating rods are fixedly connected to both ends of the worm, and support plates are rotatably connected to the surface of the rotating rods. The rotating rods facilitate axial rotation of the worm.

[0010] Furthermore, a support plate is fixedly connected to the lower surface of the placement frame. The support plate is provided to facilitate the limiting of the rotating rod.

[0011] Furthermore, a synchronous servo motor is fixedly connected to one end of the rotating rod, and the synchronous servo motor is fixedly connected to the lower surface of the placement frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting an adjustment device, the height of the equipment placement frame can be effectively adjusted, which can quickly adjust the height of the equipment. This reduces the situation where the height of the placement frame is difficult to adjust quickly when using existing equipment, causing misalignment at the connection end between the equipment pump body and the pipeline, making it difficult to install accurately. This adjustment device realizes stable and accurate adjustment of the horizontal direction of the placement frame, improving the precision installation of the pump body.

[0013] 2. In this utility model, by setting auxiliary components, the gear is limited by the cooperation between the first limiting ring, the second limiting ring and the mounting bracket, which prevents the gear from moving up and down when rotating, thus improving the practicality of the equipment.

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1-5 This utility model provides a technical solution: a parallel synchronous rotary mixed pump, including a placement frame 1, a power motor 2, a coupling 3, a pump body 4 and an adjustment device 5. The power motor 2 is fixedly connected to the upper surface of the placement frame 1, the coupling 3 is fixedly connected to the upper surface of the placement frame 1, the pump body 4 is fixedly connected to the upper surface of the placement frame 1, the output end of the power motor 2 is installed at one end of the coupling 3, and one end of the pump body 4 is installed at the end of the coupling 3 away from the power motor 2.

[0019] The placement frame 1 is welded from structural steel and has internal reinforcing beams, providing high load-bearing strength and stable support for the weight of the power motor 2 and pump body 4. Its surface is treated with anti-rust paint to adapt to the humid environment of the pump room. The power motor 2 is a three-phase asynchronous motor with overload protection, stable output speed, and provides continuous and reliable power to the pump body 4. The coupling 3 is a flexible pin coupling, which has a buffering and shock-absorbing function, compensating for installation deviations between the power motor 2 and pump body 4 and avoiding component wear caused by rigid transmission. The pump body 4 has a parallel dual-rotor structure, suitable for mixed transport of multiphase media. The internal rotors are precision-machined with small clearances, resulting in high transport efficiency.

[0020] The specific settings and functions of its adjustment device 5 and auxiliary components 6 will be described in detail below.

[0021] In this implementation scheme: The adjusting device 5 is installed on the lower surface of the placement frame 1 and is the core structure for achieving precise horizontal adjustment of the mixed-transfer pump. It can quickly correct the height deviation of the placement frame 1, ensuring precise connection between the pump body 4 interface and the pipeline, and avoiding sealing leaks or component damage caused by misalignment. The adjusting device 5 includes a support column 51 and a contact block 510. The contact block 510 is made of wear-resistant rubber and has anti-slip texture on its lower surface to enhance friction with the ground and prevent wear caused by direct metal contact with the ground. The support column 51 is installed inside the placement frame 1. The contact block 510 is fixedly connected to the lower end of the support column 51. A connecting block 54 is fixedly connected to the upper end of the support column 51. A threaded rod 53 is fixedly connected to the upper end of the connecting block 54. A limit block 52 is fixedly connected to the upper end of the threaded rod 53 for limiting movement. Block 52 is a round steel block, which is welded and fixed to the threaded rod 53 to prevent the threaded rod 53 from accidentally coming out of the gear 55, thus playing a safety protection role. The surface of the threaded rod 53 is threadedly connected to the gear 55, and the surface of the gear 55 is equipped with an auxiliary component 6. The auxiliary component 6 includes a first limiting ring 61 and a second limiting ring 62. Both the first limiting ring 61 and the second limiting ring 62 are made of wear-resistant bronze and have been polished. The clearance between them and the gear 55 is extremely small, which can both limit the axial movement of the gear 55 and reduce friction and wear. The first limiting ring 61 is fitted to the upper surface of the gear 55, and the second limiting ring 62 is fitted to the lower surface of the gear 55. The first limiting ring 61 and the second limiting ring 62 are fixedly connected by a mounting bracket 63, which is fixedly connected inside the placement frame 1.

[0022] Specifically, the first limiting ring 61 and the second limiting ring 62 are sleeved and connected to the surface of the threaded rod 53. A reasonable gap is left between the inner hole of the limiting ring and the threaded rod 53, which not only does not affect the axial movement of the threaded rod 53, but also plays a certain guiding role for the threaded rod 53 to prevent it from shaking.

[0023] In this embodiment, by setting the first limiting ring 61 and the second limiting ring 62, the gear 55 can be limited, reducing the likelihood of the gear 55 moving up and down during use, which would make it difficult for the gear 55 to smoothly drive the threaded rod 53.

[0024] Specifically, a worm gear 56 is meshed with the side of the gear 55. The worm gear 56 adopts a single-headed worm gear design, which forms a large transmission ratio with the gear 55. This can reduce the output speed of the synchronous servo motor 59, increase the adjustment torque, and ensure that the gear 55 can still be driven to rotate smoothly under heavy load. The worm gear 56 is set to facilitate the rotation of the drive gear 55.

[0025] Specifically, the two ends of the worm 56 are fixedly connected to rotating rods 57, and the surface of the rotating rods 57 is rotatably connected to a support plate 58. The rotating rods 57 are provided to facilitate the axial rotation of the worm 56.

[0026] Specifically, the support plate 58 is fixedly connected to the lower surface of the placement frame 1. The support plate 58 can strictly limit the axial displacement of the rotating rod 57, prevent the meshing clearance between the worm gear 56 and the gear 55 from changing, and ensure transmission accuracy. The support plate 58 is set to facilitate the limiting of the rotating rod 57.

[0027] Specifically, a synchronous servo motor 59 is fixedly connected to one end of the rotating rod 57. The synchronous servo motor 59 has a high-precision position control function, which can accurately control the rotation angle of the rotating rod 57, thereby achieving precise control of the lifting height of the threaded rod 53. It also has a self-locking function, which can prevent reverse rotation caused by the weight of the equipment. The synchronous servo motor 59 is fixedly connected to the lower surface of the placement frame 1.

[0028] Working principle: Parallel synchronous rotary mixed pumps are mainly used for multiphase media transportation in the petroleum, chemical and other fields. The precise connection between the pump body 4 and the pipeline directly affects the transportation efficiency and operational safety. The convenient leveling function of the adjustment device 5 is the key to ensuring the installation accuracy of the equipment. When using the equipment, the user first aligns the pipeline containing the medium to be transported with the inlet and outlet flanges of the pump body 4. Then, the pipeline is temporarily fixed, and the power motor 2 is started. The power motor 2 transmits power to the pump body 4 through the coupling 3, driving the parallel rotors inside the pump body 4 to rotate synchronously, achieving stable transport of multiphase media. The flexible coupling 3 effectively buffers the vibration of the motor and pump body 4 during operation, protecting components from impact damage. When misalignment is found between the pump body 4 interface and the pipeline, requiring height adjustment of the placement frame 1, first confirm that the entire equipment is in a stopped state, close the power motor 2 and the medium transport valve, ensuring safety during the leveling process. Start the synchronous servo motor 59 and drive the rotating rod 57 to rotate clockwise. The rotating rod 57 drives the worm gear 56 to rotate synchronously. The worm gear 56 meshes with the gear 55 on the side, driving the gear 55 to rotate counterclockwise around its own axis. With the first limiting ring 61 and the second limiting ring 62 in contact and limiting position, only rotation occurs without axial displacement. The inner wall thread of the threaded rod 53 engages with the surface thread of the threaded rod 53, converting the rotational motion into the axial upward motion of the threaded rod 53. The threaded rod 53 drives the lower connecting block 54, support column 51 and contact block 510 to rise synchronously. The support column 51 pushes the corresponding side of the placement frame 1 upward. When the upper surface of the placement frame 1 reaches a horizontal state, the synchronous servo motor 59 stops running. By setting the adjustment device 5, the height of the equipment placement frame 1 can be effectively adjusted, which plays a role in quickly adjusting the height of the equipment. This reduces the situation where the height of the placement frame 1 is difficult to adjust quickly when using the existing equipment, causing misalignment between the connection end of the equipment pump body 4 and the pipeline, making it difficult to install accurately. This adjustment device 5 realizes the stable and accurate adjustment of the horizontal direction of the placement frame 1, improving the precision installation of the pump body 4.

[0029] By setting up auxiliary component 6, in which the first limiting ring 61, the second limiting ring 62 and the mounting bracket 63 cooperate with each other, the gear 55 is limited, avoiding up and down movement when the gear 55 rotates, thus improving the practicality of the equipment.

[0030] The above description discloses only one or more preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of the present utility model still fall within the scope of the present utility model.
