Description

Technical Field

[0001] The utility model relates to the technical field of pump skids, in particular to a pump skid with multiple parallel branch pipelines. Background Art

[0002] A pump skid is an integrated fluid delivery device that typically includes a pump, motor, piping, valves, instrumentation, and other accessories, assembled on a steel base. A pump skid with multiple parallel branches means the device has multiple outlets, allowing it to deliver fluid in multiple directions or systems simultaneously.

[0003] In existing pump skids, flange and bolt connections between pipelines and pumps are a common connection method. However, frequent use can cause flange bolts to loosen. In high-pressure systems, loose bolts may cause the flange connection to be unable to withstand the design pressure, thereby causing pipeline rupture or explosion. Loose bolts will increase the vibration of the pipeline and pump. Long-term vibration will accelerate equipment wear and shorten equipment life. To this end, we propose a pump skid with multiple parallel branch pipelines. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the utility model provides a pump skid with multiple parallel branch pipelines. Through the spring return mechanism of the limiter and the clamping member, self-locking clamping of the flange and the pipeline is achieved, effectively preventing the problem of bolt loosening caused by frequent use. The clamping action of the limiter and the clamping plate ensures a tight connection between the flange and the pipeline, significantly improves the sealing performance, and reduces the risk of leakage.

[0021] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are all conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can be obtained from commercial channels. Example

[0022] like Figure 1-5 As shown, a pump skid with multiple parallel branch pipelines includes a pump skid body 1, a base 2 is installed at the bottom end of the pump skid body 1, a motor 3 is installed on the base 2, the output end of the motor 3 is connected to a pipeline 5, a pressure gauge 4 is installed on the pipeline 5, and the pipeline 5 is also connected to a pump 6. The pipeline 5 and the pump 6 are reinforced by a limiter 7. A clamping member 8 is installed on the base 2, and the clamping member 8 clamps and fixes the pipeline 5. The pipeline 5 includes a pipeline body 51 connected to the output end of the motor 3 and a first flange 52 provided on the pipeline body 51. The pump 6 includes a second flange 62 connected to the first flange 52, and a gate valve 61 connected to the second flange 62. Two sets of limiters 7 are symmetrically connected to the outer wall of the second flange 62;

[0023] The limiting member 7 includes a mounting plate 71 mounted on the outer wall of the second flange 62, an inner cavity 72 defined in the mounting plate 71, a first slide groove 73 defined in the inner cavity 72, a first slider 74 slidably connected to the first slide groove 73, a first spring 75 connected to the first slider 74, a limiting block 76 connected to the first slider 74 and slidably connected to the inner cavity 72, and a first pull rod 77 connected to the outer wall of the limiting block 76.

[0024] When the first flange 52 is connected to the second flange 62, the staff first pulls outward the two sets of first pull rods 77 at the upper and lower ends of the second flange 62, so that the first pull rods 77 drive the limit block 76 to slide outward in the inner cavity 72, thereby driving the first slider 74 to slide outward in the first slide groove 73. During the sliding process, the first spring 75 is squeezed to produce deformation until the limit block 76 moves outward to the outermost end. At this time, the staff connects the first flange 52 to the second flange 62, and then loosens the two sets of first pull rods 77 at the upper and lower ends. At this time, the restoring force generated by the elasticity of the first spring 75 itself pushes the limit block 76 to restore, and finally drives the two sets of limit blocks 76 to clamp and limit the outer wall of the first flange 52.

[0025] It is worth noting that one end of the first spring 75 is connected to the inner wall of the first slide 73, and the other end of the first spring 75 is connected to the outer wall of the first slider 74. This connection ensures that when the spring is compressed, its force is evenly distributed on the inner wall of the slide. This increases the contact area between the spring and the slide, facilitating stable transmission of the spring force. The other end of the spring is connected to the outer wall of the first slider, so that when the limit block 76 moves outward, the spring is compressed and stores energy. Once the limit block 76 is released, the restoring force of the spring can effectively push the limit block back to its initial position, thereby achieving clamping and limiting the first flange 52.

[0026] The stop block 76 is configured in a stepped shape. This design helps to increase the contact area with the first flange 52, thereby increasing the clamping force. It also facilitates positioning and guiding during connection and disconnection. The contact surface between the stop block 76 and the first flange 52 is provided with a cushion to increase the friction coefficient of the contact surface and prevent sliding. The cushion also acts as a buffer, reducing damage caused by vibration and other factors, thereby improving the reliability of the connection.

[0027] The clamping member 8 includes an auxiliary plate 81 mounted on the base 2, a second slide groove 82 defined in the auxiliary plate 81, a second slider 83 slidably connected to the second slide groove 82, a movable rod 84 connected to the second slider 83 and inserted into the auxiliary plate 81, a second spring 85 wound around the movable rod 84, a clamping plate 86 connected to one end of the movable rod 84, and a second pull rod 87 mounted on the other end of the movable rod 84.

[0028] Before fixing the pipe 5, the staff pulls the second pull rods 87 at both ends outward in advance, so that the second pull rods 87 drive the movable rod 84 to slide outward. The movable rod 84 slides outward in the second slide groove 82 through the second slider 83, squeezing the second spring 85 to deform during the sliding process until the movable rod 84 drives the clamping plate 86 to move outward to the outermost end. At this time, the pipe 5 is placed on the base 2, and then the second pull rods 87 at both ends are loosened. At this time, the restoring force generated by the elasticity of the second spring 85 itself pushes the clamping plate 86 to restore, and finally the outer walls of the two ends of the pipe body 51 are clamped and fixed;

[0029] It is worth noting that one end of the second spring 85 is connected to the outer wall of the second slider 83, similar to the first spring 75. This connection method ensures that the spring can transmit force evenly when compressed. The other end of the second spring 85 is connected to the inner wall of the second slide groove 82, so that the second spring 85 can store energy after the clamping plate 86 moves to the outermost end. Once released, the restoring force of the spring can push the clamping plate 86 back to the initial position, thereby achieving clamping and fixation of the pipe body 51.

[0030] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
