Description

Technical Field

[0001] The present invention belongs to the technical field of ceramic pump manufacturing, and particularly relates to a seal compensation type ceramic pump. Background Art

[0002] Ceramics is a material with excellent corrosion resistance and wear resistance. Ceramic pumps draw on this property, and the pump body and pump cover are made of acid-resistant ceramics. Ceramic pumps are generally centrifugal pumps, and their impellers, volutes, shaft seal chambers, and suction and discharge pipes are all made of ceramics. Currently, alumina ceramics are mainly used. It is suitable for transporting strongly corrosive liquids such as hydrochloric acid, sulfuric acid, and nitric acid, but cannot transport fluorine-containing materials and concentrated alkali solutions, etc.

[0003] During the actual use of ceramic pumps, since they are often used in complex environments, the sealing performance of ceramic pumps is prone to change due to external vibration. When the existing seal compensation type ceramic pump is connected to an external pipeline, it usually uses a gasket for sealing, and the outer wall of the external pipeline is fixed and clamped by a clamping device.

[0004] However, the existing seal compensation type ceramic pump is prone to loose connection in a vibrating environment, and the gasket is prone to compression failure under vibration pressure. If the clamping device on the seal compensation type ceramic pump clamps too tightly, it is easy to produce indentations on the surface of the external pipeline, and if it clamps too loosely, it is easy to cause poor sealing. Summary of the Invention

[0005] The purpose of the present invention is to provide a seal compensation type ceramic pump, aiming to solve the technical problem of poor sealing performance of the existing seal compensation type ceramic pump in a vibrating environment.

[0006] The present invention is realized as follows: A seal compensation type ceramic pump includes a pump body. The pump body is connected to a water pipe. The water pipe is fixedly connected to a threaded pipe. The water pipe is fixedly connected to two first telescopic rods. The two first telescopic rods are symmetrically arranged about the center of the water pipe. The telescopic ends of the two first telescopic rods are both fixedly connected to second telescopic rods. A clamping mechanism is arranged between the telescopic ends of the two second telescopic rods. The clamping mechanism can clamp and fix the connecting pipeline. An adsorption mechanism is arranged in the clamping mechanism. The adsorption mechanism can adsorb and fix to the surface of the connecting pipeline;

[0007] The water pipe is fixedly connected to a sealing mechanism. The sealing mechanism can seal the joint between the connecting pipeline and the threaded pipe;

[0008] A control system, which can ensure the sealing effect between the threaded pipe and the connecting pipeline by controlling the clamping mechanism, the adsorption mechanism, and the sealing mechanism according to the vibration magnitudes in the external horizontal and vertical directions.

[0009] Further technical solution: The clamping mechanism includes a clamp, an electric rod, a nut, and a spring;

[0010] The telescopic ends of the second telescopic rods are fixedly connected with clamps. Both ends of one of the clamps are fixedly connected with electric rods. The telescopic ends of the electric rods slide through and penetrate the other clamp. Springs are sleeved outside the telescopic ends of the electric rods, and nuts are threadedly connected to the telescopic ends of the electric rods, and the nuts are abutted against the other clamp.

[0011] Further technical solution: The adsorption mechanism includes an air pump, an air pipe and a suction cup;

[0012] The middle part of the clamp is fixedly connected with a suction cup. The suction cup can elastically expand and contract. The telescopic end of the second telescopic rod is fixedly connected with an air pump. An air pipe is communicated between the air pump and the suction cup, and a one-way valve for one-way conduction to the air pump is arranged on the air pipe.

[0013] Further technical solution: A sealing gasket is connected to the opening of the suction cup. A limiting sleeve is arranged in the clamp, and a sealing airbag is arranged in the limiting sleeve. The sealing airbag is in contact with the sealing gasket.

[0014] Further technical solution: The sealing mechanism includes an electric telescopic sleeve and a sealing seat. The electric telescopic sleeve is fixedly connected to the end face of the water pipe, and the electric telescopic sleeve is sleeved outside the threaded pipe. A plurality of sealing seats are fixedly connected to the end of the electric telescopic sleeve, and the inclined surface of the sealing seat abuts against the threaded pipe.

[0015] Further technical solution: A sealing ring is jointly fitted and connected between all the sealing seats. The surface of the sealing ring in contact with the sealing seat is set as an inclined surface. A plurality of sealing blocks are arranged on the sealing ring, and each sealing block is arranged between two adjacent sealing seats.

[0016] Further technical solution: The regulation system includes:

[0017] A monitoring module, which includes a first vibration sensor and a second vibration sensor. The first vibration sensor is connected to the telescopic end of the first telescopic rod, and the second vibration sensor is connected to the telescopic end of the second telescopic rod;

[0018] A storage module, which is used for storing the vibration frequency data of the first vibration sensor and the second vibration sensor at each moment in the monitoring module;

[0019] A processing module, which is used for comparing the vibration frequency data of the first vibration sensor and the second vibration sensor at each moment in the storage module with the preset vibration frequency data in the processing module, and forming a judgment message;

[0020] A control module, which is used for controlling the clamping mechanism, the adsorption mechanism and the sealing mechanism to ensure the sealing effect between the threaded pipe and the connecting pipe.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. The electric rod performs a contraction movement. At this time, the electric rod pushes another clamp upward through the nut, and at this time, the two clamps simultaneously clamp toward the connecting pipe in the middle, increasing the vertical connection stability between the connecting pipe and the threaded pipe;

[0023] 2. When the two clamps clamp toward the connecting pipe in the middle, at this time, the two clamps respectively drive the suction cups connected to them to adsorb to the outer wall of the connecting pipe. When the adsorption between the suction cups and the outer wall of the connecting pipe is completed, the air pump is started at this time, and the air pump further adsorbs the air in the suction cups outward, thereby increasing the adsorption force between the suction cups and the outer wall of the connecting pipe; The suction cup can not only fix the connection between the second telescopic rod and the connecting pipe, but also avoid applying a large rigid pressure to the outer wall of the external pipe, causing indentations on the surface of the external pipe;

[0024] 3. When the two clamps squeeze toward the connecting pipe in the middle, at this time, the limit sleeve abuts against the outer wall of the connecting pipe, and at the same time, the sealing airbag in the limit sleeve expands toward both sides under extrusion. The limit sleeve limits the sealing airbag, causing the sealing airbag to squeeze toward the sealing gasket. By squeezing the sealing gasket through the sealing airbag, the tightness between the suction cup and the outer wall of the connecting pipe is further increased;

[0025] 4. The electric telescopic sleeve drives all the sealing seats to abut against and seal the joint between the threaded pipe and the connecting pipe, thereby ensuring the tightness between the pump body and the connecting pipe; When the sealing seat abuts against the joint between the threaded pipe and the connecting pipe, at this time, under the reverse thrust of the connecting pipe, the sealing seat squeezes the sealing ring inward, and the sealing ring fits against the outer wall of the threaded pipe, thereby increasing the degree of fit between the sealing ring and the threaded pipe; At the same time, the sealing seats squeeze against each other, and further seal between the sealing seats through the respective sealing blocks.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] The following describes in detail the specific implementation of the present invention in conjunction with specific embodiments.

[0036] As Figures 1 - 7 shown, a sealing compensation type ceramic pump provided by the present invention includes a pump body 1, the pump body 1 is communicated with a water pipe 2, the water pipe 2 is fixedly connected with a threaded pipe 3, the water pipe 2 is fixedly connected with two first telescopic rods 9, the two first telescopic rods 9 are symmetrically arranged about the center of the water pipe 2, the telescopic ends of the two first telescopic rods 9 are fixedly connected with second telescopic rods 10, a clamping mechanism 4 is arranged between the telescopic ends of the two second telescopic rods 10, the clamping mechanism 4 can clamp and fix the connecting pipe, and an adsorption mechanism 5 is arranged in the clamping mechanism 4, and the adsorption mechanism 5 can adsorb and fix on the surface of the connecting pipe;

[0037] The water pipe 2 is fixedly connected with a sealing mechanism 6, and the sealing mechanism 6 can seal the joint between the connecting pipe and the threaded pipe 3;

[0038] A regulation system, which can control the clamping mechanism 4, the adsorption mechanism 5 and the sealing mechanism 6 according to the vibration magnitudes in the external horizontal and vertical directions to ensure the sealing effect between the threaded pipe 3 and the connecting pipe.

[0039] In this embodiment, the threaded pipe 3 is threadedly connected to the connecting pipe. Then, the clamping mechanism 4 is used to further clamp and fix the connecting pipe in the vertical direction. At the same time, the adsorption mechanism 5 is adsorbed and fixed to the outer wall of the connecting pipe. At this time, the sealing mechanism 6 is started, and the sealing mechanism 6 can seal the joint between the connecting pipe and the threaded pipe 3, thereby ensuring the sealing performance between the connecting pipe and the threaded pipe 3.

[0040] The control system controls the clamping mechanism 4, the adsorption mechanism 5, and the sealing mechanism 6 according to the vibration magnitudes in the external horizontal and vertical directions to ensure the sealing effect between the threaded pipe 3 and the connecting pipe.

[0041] As Figure 2 shown, a sealing compensation type ceramic pump provided by the present invention, the clamping mechanism 4 includes a fixture 41, an electric rod 42, a nut 43, and a spring 44;

[0042] The telescopic ends of the second telescopic rods 10 are fixedly connected with fixtures 41. Both ends of one of the fixtures 41 are fixedly connected with electric rods 42. The telescopic ends of the electric rods 42 slide through and penetrate the other fixture 41. Springs 44 are sleeved outside the telescopic ends of the electric rods 42. The telescopic ends of the electric rods 42 are threadedly connected with nuts 43, and the nuts 43 are abutted against the other fixture 41.

[0043] In this embodiment, when the electric rod 42 is started, the electric rod 42 performs a contraction movement. At this time, the electric rod 42 pushes the other fixture 41 to move upward and approach through the nut 43. At this time, the two fixtures 41 simultaneously clamp the middle connecting pipe, increasing the connection stability between the connecting pipe and the threaded pipe 3.

[0044] As Figures 1 - 5 shown, a sealing compensation type ceramic pump provided by the present invention, the adsorption mechanism 5 includes an air pump 51, an air pipe 52, and a suction cup 53;

[0045] The middle part of the fixture 41 is fixedly connected with a suction cup 53. The suction cup 53 can elastically expand and contract. The telescopic end of the second telescopic rod 10 is fixedly connected with an air pump 51. An air pipe 52 is connected between the air pump 51 and the suction cup 53. A one-way valve for one-way conduction to the air pump 51 is arranged on the air pipe 52.

[0046] In this embodiment, when the two fixtures 41 clamp the middle connecting pipe, at this time, the two fixtures 41 respectively drive the suction cups 53 connected thereto to adsorb to the outer wall of the connecting pipe. When the adsorption of the suction cups 53 to the outer wall of the connecting pipe is completed, at this time, the air pump 51 is started, and the air pump 51 further adsorbs the air in the suction cups 53 outward, thereby increasing the adsorption force between the suction cups 53 and the outer wall of the connecting pipe.

[0047] As Figure 5As shown in the figure, a sealing compensation type ceramic pump provided by the present invention, a gasket 54 is connected to the opening of the suction cup 53, a limit sleeve 7 is arranged in the clamp 41, a sealing airbag 8 is arranged in the limit sleeve 7, and the sealing airbag 8 is in contact with the gasket 54.

[0048] In this embodiment, when the two clamps 41 squeeze towards the middle connecting pipe, at this time, the limit sleeve 7 abuts against the outer wall of the connecting pipe. At the same time, the sealing airbag 8 in the limit sleeve 7 is squeezed and expands towards both sides. The limit sleeve 7 limits the sealing airbag 8, so that the sealing airbag 8 squeezes towards the gasket 54, and the gasket 54 is squeezed by the sealing airbag 8, thereby further increasing the sealing performance between the suction cup 53 and the outer wall of the connecting pipe.

[0049] As Figure 6 shown in the figure, a sealing compensation type ceramic pump provided by the present invention, the sealing mechanism 6 includes an electric telescopic sleeve 61 and a sealing seat 62. The electric telescopic sleeve 61 is fixedly connected to the end face of the water pipe 2, and the electric telescopic sleeve 61 is sleeved outside the threaded pipe 3. A plurality of sealing seats 62 are fixedly connected to the end of the electric telescopic sleeve 61, and the inclined surface of the sealing seat 62 abuts against the threaded pipe 3.

[0050] In this embodiment, the electric telescopic sleeve 61 is started to extend. The electric telescopic sleeve 61 drives all the sealing seats 62 to abut against and seal the joint between the threaded pipe 3 and the connecting pipe, thereby ensuring the sealing performance between the pump body 1 and the connecting pipe.

[0051] As Figure 6 and Figure 7 shown in the figure, a sealing compensation type ceramic pump provided by the present invention, a sealing ring 11 is jointly fitted and connected between all the sealing seats 62. The surface of the sealing ring 11 in contact with the sealing seat 62 is set as an inclined surface, and a plurality of sealing blocks 12 are arranged on the sealing ring 11, and each sealing block 12 is arranged between two adjacent sealing seats 62.

[0052] In this embodiment, when the sealing seat 62 abuts against the joint between the threaded pipe 3 and the connecting pipe, at this time, under the reverse thrust of the connecting pipe, the sealing seat 62 squeezes the sealing ring 11 inward, and the sealing ring 11 fits against the outer wall of the threaded pipe 3, thereby increasing the fitting degree between the sealing ring 11 and the threaded pipe 3; at the same time, the sealing seats 62 squeeze each other, and the sealing blocks 12 further seal between the sealing seats 62.

[0053] A sealing compensation type ceramic pump provided by the present invention, the control system includes:

[0054] A monitoring module, which includes a first vibration sensor and a second vibration sensor. The first vibration sensor is connected to the telescopic end of the first telescopic rod 9, and the second vibration sensor is connected to the telescopic end of the second telescopic rod 10;

[0055] A storage module, which is used to store the vibration frequency data of the first vibration sensor and the second vibration sensor at each moment in the monitoring module;

[0056] A processing module, which is used to compare the vibration frequency data of the first vibration sensor and the second vibration sensor at each moment in the storage module with the preset vibration frequency data in the processing module, and form judgment information;

[0057] A control module, which is used to control the clamping mechanism 4, the adsorption mechanism 5 and the sealing mechanism 6 to ensure the sealing effect between the threaded pipe 3 and the connecting pipe.

[0058] In this embodiment, when the vibration frequency of the first vibration sensor at the current moment in the processing module exceeds the preset vibration frequency threshold, it indicates that the pump body 1 is subjected to a large vertical vibration force at this time. The processing module forms judgment information, and the control module receives the judgment information and controls the clamping mechanism 4 and the sealing mechanism 6 to start;

[0059] When the vibration frequency of the second vibration sensor at the current moment in the processing module exceeds the preset vibration frequency threshold, it indicates that the pump body 1 is subjected to a large horizontal vibration force at this time. The processing module forms judgment information, and the control module receives the judgment information and controls the adsorption mechanism 5 and the sealing mechanism 6 to start.

[0060] Working principle:

[0061] Thread the threaded pipe 3 with the connecting pipe, start the electric rod 42, and the electric rod 42 performs a contraction movement. At this time, the electric rod 42 pushes another clamp 41 upward close through the nut 43. At this time, the two clamps 41 clamp towards the middle connecting pipe at the same time, increasing the vertical connection stability between the connecting pipe and the threaded pipe 3;

[0062] When the two clamps 41 clamp towards the middle connecting pipe, at this time, the two clamps 41 respectively drive the suction cups 53 connected to them to adsorb on the outer wall of the connecting pipe. When the suction cups 53 are adsorbed on the outer wall of the connecting pipe, start the air pump 51 at this time, and the air pump 51 further adsorbs the air in the suction cups 53 outwards, thereby increasing the adsorption force between the suction cups 53 and the outer wall of the connecting pipe; The suction cup 53 can not only fix the second telescopic rod 10 to the connecting pipe, but also avoid applying a large rigid pressure on the outer wall of the external pipe, causing indentations on the surface of the external pipe;

[0063] When the two clamps 41 squeeze towards the middle connecting pipe, at this time, the limiting sleeve 7 abuts against the outer wall of the connecting pipe. Meanwhile, the sealing airbag 8 in the limiting sleeve 7 is squeezed and expands towards both sides. The limiting sleeve 7 limits the sealing airbag 8, causing the sealing airbag 8 to squeeze towards the sealing gasket 54. By squeezing the sealing gasket 54 through the sealing airbag 8, the sealing performance between the suction cup 53 and the outer wall of the connecting pipe is further enhanced.

[0064] Start the electric telescopic sleeve 61 to extend. The electric telescopic sleeve 61 drives all the sealing seats 62 to abut against and seal the joint between the threaded pipe 3 and the connecting pipe, thereby ensuring the sealing performance between the pump body 1 and the connecting pipe. When the sealing seat 62 abuts against the joint between the threaded pipe 3 and the connecting pipe, at this time, under the reverse thrust of the connecting pipe, the sealing seat 62 squeezes the sealing ring 11 inward, and the sealing ring 11 fits against the outer wall of the threaded pipe 3, thereby increasing the degree of fit between the sealing ring 11 and the threaded pipe 3. At the same time, the various sealing seats 62 squeeze each other, and further seal between the various sealing seats 62 through the various sealing blocks 12.

[0065] When in the processing module, the vibration frequency of the first vibration sensor at the current moment exceeds the preset vibration frequency threshold, it indicates that the pump body 1 is subjected to a relatively large vertical vibration force at this time. The processing module forms judgment information, and the control module receives the judgment information and controls the clamping mechanism 4 and the sealing mechanism 6 to start, and increases the vertical stability and sealing performance between the pump body 1 and the connecting pipe through the cooperation of the clamping mechanism 4 and the sealing mechanism 6.

[0066] When in the processing module, the vibration frequency of the second vibration sensor at the current moment exceeds the preset vibration frequency threshold, it indicates that the pump body 1 is subjected to a relatively large horizontal vibration force at this time. The processing module forms judgment information, and the control module receives the judgment information and controls the adsorption mechanism 5 and the sealing mechanism 6 to start. The adsorption mechanism 5 adsorbs and fixes between the second telescopic rod 10 and the connecting pipe, and at the same time, the sealing mechanism 6 increases the horizontal limiting force on the connecting pipe in the horizontal direction, and increases the horizontal stability and sealing performance between the pump body 1 and the connecting pipe through the cooperation of the adsorption mechanism 5 and the sealing mechanism 6.

[0067] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
