Description

Technical Field

[0001] The utility model belongs to the technical field of mud pumps, in particular to a water-passing device of a drilling rig mud pump. Background Art

[0002] During use, the drilling rig mud pump generally conveys a mixture of mud and water. Due to the uneven density of the mixture of mud and water and the periodicity of the mud pump itself when working, the mud pipeline will vibrate during the conveying process. When this vibration is too large, it will not only affect the working efficiency of the mud pump, but also easily cause the drilling direction to deviate, affecting the drilling efficiency. Therefore, it is necessary to buffer the output medium in the water-passing device of the mud pump to reduce its vibration in the pipeline. Utility Model Content

[0003] In order to solve the problem in the prior art that the mud pipeline vibrates greatly during the mud pump transportation process, affecting production and pump body quality, the utility model provides a water-passing device for a drilling rig mud pump. By adding a vibration ring in the mud pipeline, the speed of the conveying medium is buffered by the vibration characteristics of the vibration ring itself, thereby reducing the impact of the conveying medium on the pipeline, making it more stable, and improving the working efficiency and service life of the mud pump.

[0004] The utility model provides a water-passing device for a drilling rig mud pump, and its technical solution for solving the technical problem includes a pipe body and a vibration ring. At least one vibration ring is provided in the pipe body along the axial direction of the pipe body, and the vibration ring is connected to the inner side wall of the pipe body by sliding along the axial direction of the pipe body. A spring is connected between the vibration ring and the inner side wall of the pipe body. The sliding of the vibration ring along the axial direction of the pipe body will cause the spring to be stretched or compressed, and a plurality of support rods extending toward the center of the vibration ring are provided on the inner side wall of the vibration ring.

[0005] In the present technical solution, the pipe body can be a part of the mud pump delivery pipeline, or it can be set as a separate component, which is assembled and connected with the pipeline of the mud pump when in use. By setting a vibration ring in the pipe body and the design of the support rod on the vibration ring, the support rod will be subjected to the positive impact of the conveying medium. When it is impacted by the mud pump delivery medium, the spring will be stretched under the action of the fluid impact, and due to the recovery characteristics of the spring, it will cause the vibration ring to move in the opposite direction. In this way, when the fluid is unstable, the vibration ring will produce continuous vibration, impacting the fluid flowing through it, reducing the speed of the fluid, and thereby reducing the impact of the fluid on the subsequent mud pipeline, playing a buffering effect, and improving the working efficiency and service life of the mud pump.

[0006] Preferably, an annular groove is formed on the inner sidewall of the tube body, and an annular protrusion is formed on the outer sidewall of the vibration ring. The annular protrusion is slidably connected to the annular groove, and a spring is connected between the end face of the annular protrusion and the sidewall of the annular groove. This arrangement facilitates installation of the vibration ring, and the matching structure of the annular protrusion and the annular groove allows the vibration ring to slide and rotate, thereby providing a better buffering effect on the fluid.

[0007] Preferably, multiple springs are connected between the annular protrusion and the sidewall of the annular groove, each spring being in the shape of a spiral around the axis of the tube. By designing the springs in a spiral shape, when the vibration ring is impacted, the springs act to not only slide along the axial direction of the tube but also rotate circumferentially, thereby providing a better buffering effect on the fluid.

[0008] Preferably, springs are connected between the two end faces of the annular protrusion and the two side walls of the annular groove. This facilitates structural stability during installation of the vibration ring and ensures its adaptability. The springs are distributed on both sides, making it easier to install the vibration ring without having to consider the flow direction of the fluid.

[0009] Preferably, the annular protrusion is set in the middle of the vibration ring, and the length of the vibration ring is greater than 3 times the width of the annular groove. Through this arrangement, the length of the vibration ring is much greater than the width of the annular groove, which can prevent the edge of the vibration ring from getting stuck in the groove and causing malfunctions.

[0010] Preferably, the vibration ring has an eccentric structure, which makes it easier for the vibration ring to vibrate and helps to improve the buffering effect.

[0011] Preferably, the support rods inside the vibration ring are unevenly distributed in the vibration ring so that the vibration ring forms an eccentric structure. The eccentricity is formed by the different distribution patterns of the support rods, and the eccentric structure is easy to construct.

[0012] Preferably, 2-5 groups of vibration rings are sequentially arranged and distributed along the axial direction of the tube body, which can further improve the buffering effect.

[0013] Preferably, connecting flanges are provided at both ends of the pipe body, and connecting holes are provided on the connecting flanges to facilitate connection with the mud pipeline.

[0014] In summary, the technical solution of the present invention has at least the following beneficial effects:

[0015] 1. By adding a vibration ring in the mud pipeline, the vibration characteristics of the vibration ring itself can buffer the speed of the conveying medium, reduce the impact of the conveying medium on the pipeline, make it more stable, and improve the working efficiency and service life of the mud pump;

[0016] 2. The design of the spring and its own spiral structure can increase the vibration frequency and amplitude of the vibration ring, which is more conducive to buffering;

[0017] 3. The eccentric structure of the vibration ring is more conducive to the vibration of the vibration ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See attached Figure 1-5One embodiment of the water-passing device of a drilling rig mud pump of the utility model includes a pipe body 1 and a vibrating ring 2. At least one vibrating ring 2 is provided in the pipe body 1 along the axial direction of the pipe body 1. The vibrating ring 2 is connected to the inner side wall of the pipe body 1 by sliding along the axial direction of the pipe body 1. A spring 3 is connected between the vibrating ring 2 and the inner side wall of the pipe body 1. The sliding of the vibrating ring 2 along the axial direction of the pipe body 1 will cause the spring 3 to be stretched or compressed. A plurality of support rods 4 extending toward the center thereof are provided on the inner side wall of the vibrating ring 2.

[0028] In this embodiment, the pipe body 1 can be part of the mud pump delivery pipeline, or it can be set as a separate component and assembled and connected with the mud pump pipeline during use. When it is set as a separate component, connecting flanges 7 are provided at both ends of the pipe body 1, and connecting holes 8 are provided on the connecting flanges 7 to facilitate connection with the mud pipeline.

[0029] In addition, this embodiment sets a vibration ring 2 in the pipe body 1, and designs a support rod 4 in the vibration ring 2. When working, the support rod 4 will be subjected to the frontal impact of the conveying medium, and the extension of the support rod 4 to the center of the vibration ring 2 preferably has a certain margin, that is, it does not extend to the center position, and a larger flow space is left as much as possible in the center of the vibration ring 2. The design of the support rod 4 only needs to ensure that it can withstand a certain degree of impact force. When the support rod 4 is impacted by the mud pump conveying medium, the spring 3 will be stretched in the flow direction under the action of the fluid impact. Due to the recovery characteristics of the spring 3 after stretching, it will cause the vibration ring 2 to move in the opposite direction. In this way, when the fluid is unstable, the vibration ring 2 will generate continuous vibration under the action of the fluid and the spring 3, and collide with the fluid flowing through here, reducing the speed of the fluid, thereby reducing the impact of the fluid on the subsequent mud pipeline, playing a buffering effect, and improving the working efficiency and service life of the mud pump.

[0030] In order to achieve the installation of the vibration ring 2, one embodiment of the present invention is that an annular groove 5 is opened on the inner wall of the tube body 1, and an annular protrusion 6 is provided on the outer wall of the vibration ring 2. The annular protrusion 6 is slidably connected in the annular groove 5, and the spring 3 is connected between the end surface of the annular protrusion 6 and the side wall of the annular groove 5. In this embodiment, the width of the annular protrusion 6 is smaller than the width of the annular groove 5. See the attached Figure 1 、 5 , which facilitates the installation of the vibration ring 2, and the matching structure of the annular protrusion 6 and the annular groove 5 allows the vibration ring 2 to both slide and rotate, which can better buffer the fluid.

[0031] See Attachment Figure 2Multiple springs 3 are connected between the annular protrusion 6 and the sidewall of the annular groove 5. Each spring 3 is in a helical shape around the axis of the tube 1. The helical design of the springs 3 allows the vibration ring 2 to not only slide axially along the tube 1 but also rotate circumferentially when impacted, providing a better buffering effect on the fluid.

[0032] See attached Figure 2 Springs 3 are connected between the two end faces of the annular protrusion 6 and the two side walls of the annular groove 5. This facilitates structural stability during installation of the vibration ring 2 and ensures its adaptability. The structure of the springs 3 distributed on both sides allows the vibration ring 2 to be installed without considering the flow direction of the fluid, that is, without having to consider the front and back issues, making installation easy.

[0033] In one embodiment of the present invention, the annular protrusion 6 is located in the middle of the vibration ring 2, and the length of the vibration ring 2 is greater than three times the width of the annular groove 5. This arrangement makes the length of the vibration ring 2 much greater than the width of the annular groove 5, preventing the edge of the vibration ring 2 from getting stuck in the groove and causing a malfunction.

[0034] In order to make the vibration ring 2 more vibrating, the vibration ring 2 of the present invention is an eccentric structure. This makes it easier for the vibration ring 2 to vibrate, which helps to improve the buffering effect. In this embodiment, the support rods 4 inside the vibration ring 2 can be unevenly distributed in the vibration ring 2 to form an eccentric structure of the vibration ring 2. Figure 3 The eccentricity is formed by the different distribution patterns of the support rods 4, and the eccentric structure is easy to construct.

[0035] In order to achieve a better buffering effect, 2-5 groups of vibration rings 2 are sequentially arranged and distributed along the axial direction of the tube body 1. The structure of multiple groups of design can greatly improve the buffering effect.

[0036] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the scope of protection of the technical solution of the utility model.
