Description

Technical Field

[0001] This utility model relates to the field of self-priming shielded electric pump technology, specifically a gas delivery self-priming shielded electric pump. Background Technology

[0002] Self-priming shielded electric pumps achieve efficient and leak-free fluid transfer through their unique shielded motor design and internal media circulation system, while also possessing excellent self-priming capabilities. They are ideal for applications requiring low maintenance and high reliability, such as gas delivery.

[0003] Although self-priming shielded electric pumps have efficient and leak-free fluid transfer capabilities, they inevitably generate vibrations during operation. These vibrations are transmitted to the flange connection, and over time, continuous vibrations may cause the flange connection to loosen or wear, leading to potential leakage risks. This not only causes unnecessary resource losses but also poses safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a self-priming shielded electric pump for gas delivery, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A self-priming shielded electric pump for gas delivery includes a pump body, an external inlet pipe, an external outlet pipe, and a base. The outer surface of the pump body is connected to a main body inlet pipe and a main body outlet pipe, respectively. Both the main body inlet pipe and the main body outlet pipe have a main body flange installed at their ends. Both the external inlet pipe and the external outlet pipe have external flanges installed at their ends. The external flanges are connected to the main body flanges by connecting bolts. A first sealing gasket is provided between the main body flange and the external flange. The inner wall of the main body flange has a first inclined portion, and the lower surface of the external flange has a second inclined portion that matches the first inclined portion. A second sealing gasket is provided between the first inclined portion and the second inclined portion.

[0007] Therefore, the first sealing gasket can play a first sealing role. When the outer flange and the body flange are tightly combined, the second sealing gasket is squeezed by the first and second inclined surfaces to form a second seal, thus playing a double sealing role. This can reduce the risk of leakage and avoid unnecessary resource loss and safety hazards.

[0008] Furthermore, the upper surface of the base is provided with an installation groove, and the bottom of the pump body is provided with an installation seat through a support plate. The installation seat matches the installation groove. Two insertion holes are provided on both outer surfaces of the installation seat. The base is provided with an inner groove, and an insertion mechanism that engages with the insertion holes is provided inside the inner groove.

[0009] Furthermore, the insertion mechanism includes a threaded rod with a pair of reverse threads rotatably mounted inside the inner groove. A movable plate is mounted on each of the two reverse threads of the threaded rod. Fixed blocks are mounted on both sides of the outer surface of the movable plate, and insertion rods are mounted on the outer surface of the fixed blocks.

[0010] Furthermore, the end of the threaded rod extends to the outside of the base and is fitted with a side block. A fixing bolt is installed inside the side block, and a threaded hole is opened on the outer surface of the base, with the fixing bolt matching the threaded hole.

[0011] Furthermore, a gas leak alarm is installed on the upper surface of the external flange, and a groove is formed on the lower surface of the external flange, with the groove positioned between the first and second sealing gaskets, and the detection probe of the gas leak alarm penetrating into the groove.

[0012] Furthermore, the end of the insertion rod has a conical structure, and the inner wall structure of the insertion hole matches the insertion rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] 1. This utility model provides a double sealing function through the setting of a first sealing gasket and a second sealing gasket. Furthermore, the gas leak alarm and detection probe can detect gas in the groove. When the first sealing gasket leaks, gas enters the groove and is detected by the detection probe. At this time, due to the second sealing effect of the second sealing gasket, the gas remains in a non-leaking state, thus reminding the staff to replace the first sealing gasket in time to avoid further leakage.

[0015] 2. This utility model enables quick assembly and disassembly of the pump body through the insertion mechanism and the insertion hole, thus facilitating the inspection or replacement of the pump body and improving the portability of maintenance. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0025] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] Please see Figures 1-6 This utility model provides a self-priming shielded electric pump for gas delivery, comprising a pump body 100, an external inlet pipe 104, an external outlet pipe 105, and a base 107. The outer surface of the pump body 100 is connected to a main body inlet pipe 101 and a main body outlet pipe 102, respectively. A main body flange 103 is installed at the end of both the main body inlet pipe 101 and the main body outlet pipe 102. An external flange 106 is installed at the end of both the external inlet pipe 104 and the external outlet pipe 105. The external flange 106 is connected to the main body flange 103 by connecting bolts 112. A first sealing gasket 108 is provided between the main body flange 103 and the external flange 106. The inner wall of the main body flange 103 is provided with a first inclined surface 109, and the lower surface of the external flange 106 is provided with a second inclined surface 110 that matches the first inclined surface 109. A second sealing gasket 111 is provided between the first inclined surface 109 and the second inclined surface 110.

[0027] In use, the two main flanges 103 are connected to the two external flanges 106 respectively using connecting bolts 112. Before connection, the first sealing gasket 108 is placed between the main flange 103 and the external flange 106, and the second sealing gasket 111 is placed between the first inclined portion 109 and the second inclined portion 110. When the main flange 103 and the external flange 106 are tightly connected by the connecting bolts 112, the first sealing gasket 108 and the second sealing gasket 111 will be squeezed at the same time, causing them to deform and fit tightly between the main flange 103 and the external flange 106, thus forming a double sealing effect. When the first sealing gasket 108 leaks, the second sealing gasket 111 can still play a sealing role, thereby reducing the risk of leakage and avoiding unnecessary resource loss and safety hazards.

[0028] Specifically, the upper surface of the base 107 is provided with a mounting groove 200, and the bottom of the pump body 100 is provided with a mounting base 202 via a support plate 201. The mounting base 202 matches the mounting groove 200. Two insertion holes 203 are provided on both outer surfaces of the mounting base 202. The base 107 is provided with an inner groove 204. The inner groove 204 is provided with a plug-in mechanism 300 that engages with the insertion holes 203. Through the plug-in engagement of the plug-in mechanism 300 and the insertion holes 203, the pump body 100 can be quickly disassembled and assembled, thus facilitating the inspection or replacement of the pump body 100 and improving the portability of maintenance.

[0029] Specifically, the insertion mechanism 300 includes a threaded rod 301 with a pair of reverse threads rotatably mounted inside the inner groove 204. Movable plates 302 are mounted on both reverse threads of the threaded rod 301. Fixing blocks 303 are mounted on both sides of the outer surface of the movable plates 302. Insertion rods 304 are mounted on the outer surface of the fixing blocks 303. When installing the pump body 100, the mounting base 202 can be placed into the mounting groove 200 first, and then the threaded rod 301 can be turned. Due to the reverse threads, the surface of the threaded rod... The two movable plates 302 can move closer or further apart simultaneously. Therefore, by bringing the two movable plates 302 closer together, they can drive the insertion rod 304 into the insertion hole 203, thereby fixing the mounting base 202 and completing the installation of the pump body 100. When removing the pump body 100, simply turn the threaded rod 301 in the opposite direction to move the two movable plates 302 further apart and pull the insertion rod 304 out of the insertion hole 203, thereby releasing the fixing of the mounting base 202 and removing the pump body 100.

[0030] Specifically, the end of the threaded rod 301 extends to the outside of the base 107 and is fitted with a side block 400. A fixing bolt 401 is installed inside the side block 400. A screw hole 402 is provided on the outer surface of the base 107. The fixing bolt 401 matches the screw hole 402. After the pump body 100 is installed by turning the threaded rod 301, the fixing bolt 401 is aligned with the screw hole 402. Then, the fixing bolt 401 is screwed into the screw hole 402, which can prevent the threaded rod 301 from reversing. This ensures that the insertion rod 304 is not affected by vibration and is pulled out of the insertion hole 203 during the operation of the pump body 100, thus improving safety.

[0031] Specifically, a gas leak alarm 500 is installed on the upper surface of the external flange 106, and a groove 501 is formed on the lower surface of the external flange 106. The groove 501 is located between the first sealing gasket 108 and the second sealing gasket 111. The detection probe 502 of the gas leak alarm 500 penetrates into the groove 501. Through the arrangement of the gas leak alarm 500 and the detection probe 502, gas can be detected in the groove 501. When the first sealing gasket 108 leaks, gas enters the groove 501 and is detected by the detection probe 502. At this time, due to the second sealing effect of the second sealing gasket 111, the gas is still in a non-leaking state, thus reminding the staff to replace the first sealing gasket 108 in time to avoid further leakage.

[0032] Specifically, the end of the insertion rod 304 has a conical structure, and the inner wall structure of the insertion hole 203 matches the insertion rod 304. The conical structure facilitates the precise insertion of the insertion rod 304 into the insertion hole 203. When the insertion rod 304 is inserted into the insertion hole 203 and fits tightly against it, the gap between the two can be reduced, thereby improving the stability of the connection.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
