Description

Technical Field

[0001] This invention relates to the field of pump vibration damping devices, and in particular to a pump vibration damping device and its damping method. Background Technology

[0002] As a machine for conveying or pressurizing liquids, water pumps are typically used to transport liquids such as water. During operation, water pumps generate strong vibrations, which can reduce the mechanical strength and rigidity of the pump's components, causing severe wear on sealing parts and reducing the pump's service life. Therefore, specialized vibration damping devices are needed to reduce vibration.

[0003] When existing pump vibration damping devices support and dampen the pump body, if the pump body is subjected to external forces from other directions that press down on the damping device, it will cause the pump body on the damping device to tilt, eventually causing the pump body to fall off the damping device. This affects the safety during use and damages the pump body, resulting in unnecessary losses. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of existing pump designs tipping over and being damaged when subjected to external forces from other directions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pump vibration damping device and its vibration damping method include a base, a vibration damping mechanism installed at the bottom of the base, a first sliding groove opened at each of the four corners of the bottom of the base, a second sliding groove opened on both sides of the first sliding groove, a side vibration damping mechanism slidably installed inside each of the first sliding grooves, and a support mechanism fixedly installed above each of the second sliding grooves. One side vibration damping mechanism and two support mechanisms form a group, and a mounting plate is fixedly installed on the top of the side vibration damping mechanism and the two support mechanisms. A pump body is threadedly installed on the top of the mounting plate and the top of the vibration damping mechanism.

[0007] The side vibration damping mechanism includes a first slider, which is slidably installed in a first groove. A first rotating seat and a push arm are fixedly connected to the top of the first slider. The push arm is located on the side close to the vibration damping mechanism. A gas vibration damper is rotatably installed on the first rotating seat. A second rotating seat is rotatably installed on the end of the gas vibration damper away from the first rotating seat. The second rotating seat is fixedly connected to the bottom of the mounting plate. A connecting air pipe is fixedly connected to the air inlet end of the gas vibration damper.

[0008] An inclined block is fixedly connected to the side of the push arm near the support mechanism, and a second slider is fixedly connected to the bottom of the push arm. The second slider is slidably installed in the second slide groove.

[0009] The support mechanism includes a limiting component and a third rotating seat. The limiting component is fixedly installed above the second slide groove. A top block is fixedly connected to the top of the limiting component, and a connecting piece is rotatably installed on the top block.

[0010] The third rotating seat is fixedly connected to one side of the inner wall of the base. A connecting rod is rotatably mounted on the third rotating seat. An installation groove is provided on the connecting rod. A sliding rod is slidably mounted inside the installation groove. An installation groove is fixedly connected to the end of the sliding rod near the third rotating seat. The end of the installation groove away from the sliding rod is fixedly connected to the inner wall of the installation groove. A connecting piece is rotatably mounted on the end of the sliding rod near the second spring. A fourth rotating seat is rotatably mounted on the end of the sliding rod away from the second spring. The fourth rotating seat is fixedly connected to the bottom of the mounting plate.

[0011] Preferably, the limiting component includes a fixing frame, which is fixedly connected to the bottom of the base. A fixing cylinder is fixedly connected to the fixing frame, and a sliding column is slidably installed inside the fixing cylinder. A third spring is sleeved on the sliding column, and the top of the third spring is fixedly connected to the top of the inner wall of the fixing cylinder.

[0012] Preferably, the sliding column has a limiting annular groove, a connecting column is fixedly connected to the bottom of the sliding column, the connecting column has an inclined surface on the side near the inclined block, the inclined block is used to lift the connecting column, and a locking assembly is fixedly connected to both sides of the fixed cylinder.

[0013] Preferably, the positioning assembly includes two mounting cylinders, which are respectively fixedly connected to both sides of the fixed cylinder. A pull rod is slidably mounted on the mounting cylinder, and a limit plate is fixedly connected to the pull rod. The limit plate is located inside the mounting cylinder.

[0014] Preferably, a fourth spring is fixedly connected to the side of the limiting plate away from the sliding column, the fourth spring is coaxially arranged with the pull rod, a locking post is fixedly connected to the side of the limiting plate away from the fourth spring, the limiting ring groove is used to limit the locking post, and a pull plate is fixedly connected to the end of the pull rod away from the limiting plate.

[0015] Preferably, the vibration damping mechanism includes a housing, which is fixedly connected to the bottom of the base. Multiple hydraulic rods are fixedly connected to the bottom of the inner wall of the housing. The multiple hydraulic rods are arranged in a cross shape, and a cross-shaped placement plate is fixedly connected to the top of the multiple hydraulic rods. Each hydraulic rod is fitted with a first spring.

[0016] Preferably, the steps include:

[0017] S1. Adjust the softness or stiffness of the gas damper by adjusting the nitrogen pressure inside the gas damper according to the actual weight of the pump to be installed.

[0018] S2. Place the pump body on the vibration damping mechanism and install the pump body on the mounting plate using threaded bolts;

[0019] S3. When the pump body is working, the vibration of the pump body is transmitted to the cross placement plate and the mounting plate. The vibration is damped by the first spring and hydraulic rod under the cross placement plate, and also by the gas vibration damper under the mounting plate.

[0020] S4. When the pump body is pressed down by external forces in other directions, when the pressure reaches the buffer limit of the gas damper, the gas damper pushes the first rotating seat to move. The first rotating seat pushes the first slider and the push arm on the first slider to slide along the first sliding groove, so that the inclined block pushes the connecting column upward, the connecting column pushes the top block and the connecting piece on the top block, and at the same time the locking column slides into the limiting ring groove to limit the sliding column, and the connecting piece supports the sliding rod and the connecting rod.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This invention utilizes a combination of a side damping mechanism, a support mechanism, and a damping mechanism. During use, the user adjusts the nitrogen pressure within the gas damper to control its stiffness based on the actual weight of the pump to be installed. The pump body is placed on the damping mechanism and mounted on the mounting plate using threaded bolts. When the pump is in operation, its vibration transmits to the cross-shaped placement plate and the mounting plate. The vibration is absorbed by the first spring and hydraulic rod below the cross-shaped placement plate, and also by the gas damper below the mounting plate. This allows for easy adjustment of the damper's stiffness for different pump bodies, improving the device's applicability. Furthermore, the support mechanism enhances overall stability.

[0023] 2. This invention utilizes a combination of a side damping mechanism, a support mechanism, a limiting component, and a locking component. When the pump body is pressed down by external forces from other directions, and the pressure reaches the buffer limit of the gas damper, the gas damper pushes the first rotating seat to move. The first rotating seat then pushes the first slider and the push arm on the first slider to slide along the first sliding groove. This causes the inclined block to lift the connecting column upwards, and the connecting column to lift the top block and the connecting piece on the top block. Simultaneously, the locking column slides into the limiting ring groove to limit the sliding column. The connecting piece supports the sliding rod and the connecting rod, providing accurate support in the tilting direction. This reduces the probability of the pump body tipping over, thereby reducing the probability of the pump body falling and improving the safety of the machinery. This device has a small footprint, thus improving the utilization rate of the site. Attached Figure Description

The second rotating seat 304 is fixedly connected to the bottom of the mounting plate 6. A connecting air pipe 3031 is fixedly connected to the air inlet end of the gas damper 303.

[0037] A wedge block 3013 is fixedly connected to the side of the push arm 3011 near the support mechanism 4, and a second slider 3012 is fixedly connected to the bottom of the push arm 3011. The second slider 3012 is slidably installed in the second slide groove 102.

[0038] The support mechanism 4 includes a limiting component 401 and a third rotating seat 404. The limiting component 401 is fixedly installed above the second slide 102. A top block 402 is fixedly connected to the top of the limiting component 401, and a connector 403 is rotatably installed on the top block 402.

[0041] In use, the user adjusts the nitrogen pressure within the gas damper 303 to control its stiffness based on the actual weight of the pump to be installed. The pump body is placed on the damping mechanism 2 and mounted on the mounting plate 6 using threaded bolts. When the pump is working, its vibration transmits to the cross-shaped placement plate 204 and the mounting plate 6. The vibration is absorbed by the first spring 203 and hydraulic rod 202 below the cross-shaped placement plate 204, and also by the gas damper 303 below the mounting plate 6. This allows for adjustment of the stiffness of the gas damper 303 for different pump bodies, improving the applicability of the device. Furthermore, the support mechanism 4 enhances the overall stability.

[0042] Example 2:

[0043] Please see Figure 3-8 The difference from Example 1 is that:

[0044] The limiting component 401 includes a fixing frame 4011, which is fixedly connected to the bottom of the base 1. A fixing cylinder 4012 is fixedly connected to the fixing frame 4011. A sliding column 4013 is slidably installed inside the fixing cylinder 4012. A third spring 4014 is sleeved on the sliding column 4013.

[0048] When the pump body is pressed down by external forces from other directions, when the pressure reaches the buffer limit of the gas damper 303, the gas damper 303 pushes the first rotating seat 302 to move. The first rotating seat 302 pushes the first slider 301 and the push arm 3011 on the first slider 301 to slide along the first sliding groove 101, so that the inclined block 3013 pushes the connecting column 4015 upward.
