DETAILED DESCRIPTION
[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.
[0016] Example: See Figure 1 - Figure 4 The utility model provides a technical solution: a pressure drop test bench suitable for demulsifier preparation, comprising: a test bench 1; a water pipe 2, the water pipe 2 is used to convey the test fluid, and the outer wall of the water pipe 2 is fixedly connected to the outer wall of the test bench 1; an operating block 3, the bottom of the operating block 3 is fixedly connected to the bottom of the inner wall of the test bench 1; a supporting device 4, the supporting device 4 is used to support the experimental pipeline, and the bottom of the supporting device 4 is slidably connected to the top of the operating block 3; the supporting device 4 includes a supporting platform 41, the inner wall of the supporting platform 41 is rotatably connected with a bidirectional screw 42, the side of the bidirectional screw 42 away from the test bench 1 is fixedly connected with a knob 43, both ends of the bidirectional screw 42 are threadedly connected with movable blocks 46, the outer wall of the movable block 46 is fixedly connected with a connecting tube 44, and the middle part of the outer wall of the connecting tube 44 is slidably connected with a clamp Plate 45, the inner wall of the clamping plate 45 is fixedly connected with a force storage spring 47, and the inner wall of the clamping plate 45 is slidably connected with a clamping device 48. Since the movable block 46 is connected to the clamping plate 45 through the connecting tube 44, the movement of the clamping plate 45 can be controlled by controlling the movement of the movable block 46. When the clamping plate 45 contacts the outer wall of the pipeline, the knob 43 is still turned to make the clamping plate 45 slide along the connecting tube 44 and squeeze the force storage spring 47, thereby making the force storage spring 47 in a compressed state. At this time, stop turning the knob 43. When the force storage spring 47 is compressed, it will generate an elastic force to resist the squeezing, and this elastic force will act on the clamping plate 45. The clamping plate 45 will apply prestress to the outer wall of the pipeline through this force. The prestress is used to resist the impact of the fluid, so that when the fluid impacts the inner wall of the pipeline, it is difficult to vibrate the entire pipeline.
[0017] The operating block 3 includes a fixed plate 31, the inner wall of the fixed plate 31 is slidably connected with a sliding block 33 through a sliding groove 32, and the sliding groove 32 is opened in the wall of the fixed plate 31, the outer wall of the movable block 46 is fixedly connected to the end of the force storage spring 47 away from the clamping plate 45, the bottom of the fixed plate 31 is fixedly connected to the bottom of the inner wall of the experimental table 1, the top of the fixed plate 31 is slidably connected to the bottom of the support table 41, the top of the outer wall of the support table 41 is fixedly connected to the top of the sliding block 33, a supporting device 4 is provided to support the pipeline, and the supporting device 4 on the moving operating block 3, at this time the sliding block 33 moves in the sliding groove 32, so that the support table 41 can move on the fixed plate 31 and move to the middle of the pipeline, so that the supporting device 4 can support the pipeline.
[0018] The clamping device 48 includes a sliding column 481, the outer wall of which is slidably connected to the inner wall of the clamping plate 45 through a movable groove 482, and the movable groove 482 is opened in the wall of the clamping plate 45, the outer wall of the sliding column 481 is rotatably connected to a rotating plate 484, and the bottom of the rotating plate 484 is fixedly connected to an extension plate 485, and the end of the sliding column 481 away from the rotating plate 484 is fixedly connected to a compression spring 483, and the end of the compression spring 483 away from the rotating plate 484 is fixedly connected to the inner wall of the clamping plate 45, and the outer wall of the rotating plate 484 is rotatably connected to the outer wall of the clamping plate 45. When the pipeline slides down, the pipeline The outer wall of the channel pushes the protruding part of the extension plate 485 into the clamping plate 45. Due to the limiting effect of the sliding column 481 on the rotating plate 484, the upper part of the rotating plate 484 is squeezed in the direction of the central axis of the pipeline. Since the upper position of the rotating plate 484 is higher than the axial position of the pipeline, the rotating plate 484 limits the pipeline in the up and down directions. At the same time, the rotating plate 484 pushes the sliding column 481 to slide along the movable groove 482, squeezing the compression spring 483. The compression spring 483 will generate an outward thrust when squeezing, and this thrust will assist the rotating plate 484 to further clamp the pipeline.
[0019] Working principle:
[0020] When in use, the water pipe 2 on the experimental table 1 is connected to an external experimental pipe, and fluids with different demulsifiers are circulated in the pipe, and experimental data are obtained by monitoring the fluid. In this process, a support device 4 is set to support the pipe, and the support device 4 on the moving operation block 3 is moved. At this time, the sliding block 33 moves in the sliding groove 32, so that the support table 41 can move on the fixed plate 31 and move to the middle of the pipe. At this time, the pipe is already on the support table 41. The bidirectional screw 42 is driven to rotate by turning the knob 43. Due to the thread setting of the bidirectional screw 42, the bidirectional screw 42 can drive the movable block 46 to move closer or farther from each other. By observing the diameter of the pipe, the bidirectional screw 42 is rotated to control the movement of the movable block 46 Since the movable block 46 is connected to the clamping plate 45 through the connecting tube 44, the movement of the clamping plate 45 can be controlled by controlling the movement of the movable block 46. When the clamping plate 45 contacts the outer wall of the pipe, the knob 43 is still turned to make the clamping plate 45 slide along the connecting tube 44 and squeeze the force storage spring 47, thereby making the force storage spring 47 in a compressed state. At this time, the knob 43 is stopped from being turned. When the force storage spring 47 is compressed, an elastic force resisting the squeezing will be generated, and the elastic force will act on the clamping plate 45. The clamping plate 45 will apply prestress to the outer wall of the pipe through the force. The prestress is used to resist the impact of the fluid, so that when the fluid impacts the inner wall of the pipe, it is difficult to vibrate the entire pipe, thereby finally achieving the purpose of preventing the pipe from vibrating.
[0021] A clamping device 48 is provided to limit the pipe on the supporting device 4 in the up and down directions. When the pipe slides in along the outer wall of the clamping plate 45, it contacts the outer walls of the rotating plate 484 and the extension plate 485 in turn. Due to the center of gravity setting of the combination of the rotating plate 484 and the extension plate 485, the curvature of the outer wall of the rotating plate 484 is consistent with that of the clamping plate 45, and the extension plate 485 is slightly extended. When the pipe slides down, the outer wall of the pipe pushes the extended part of the extension plate 485 into the inside of the clamping plate 45. Due to the limiting effect of the sliding column 481 on the rotating plate 484, the upper part of the rotating plate 484 is pressed against the middle of the pipe. The rotating plate 484 is squeezed in the direction of the central axis position. Since the upper position of the rotating plate 484 is higher than the axial position of the pipe, the rotating plate 484 limits the pipe in the up and down directions. At the same time, the rotating plate 484 pushes the sliding column 481 to slide along the movable groove 482, squeezing the compression spring 483. The compression spring 483 will generate an outward thrust when squeezing, and this thrust will assist the rotating plate 484 to further clamp the pipe. By clamping the pipe downward and cooperating with the supporting force of the support platform 41, the pipe is limited in the up and down directions, making it difficult to generate fluctuations, thereby preventing the pipe from jumping out of the support device 4.
