Technical Field

[0001] The utility model relates to the technical field of high-pressure large-tonnage main pumps, and particularly relates to a high-pressure large-tonnage main pump. Background Technique

[0002] High-pressure large-tonnage main pumps usually refer to pump products used in high-pressure, large-flow and large-tonnage working conditions. These pumps generally need to have characteristics such as high strength, high reliability and durability to meet the needs of different application fields.

[0003] When the existing high-pressure large-tonnage main pumps are in use, filters are used to filter fluids. However, most of the existing filters are fixed inside the high-pressure large-tonnage main pumps. When the filtering effect of the filter decreases after long-term use, it needs to be replaced and cleaned. When disassembling and installing, the entire device needs to be disassembled for replacement, which is very inconvenient. Content of the Utility Model

[0024] The fixed disk 80 is fixed on the surface of the inlet 3. A cavity 81 is formed inside the fixed disk 80. A ring 82 is rotatably connected inside the cavity 81. A contact hole 83 is formed on the surface of the ring 82. A limiting rod 84 abuts against the inner wall of the contact hole 83. A limiting hole 85 is formed on the surface of the fixed disk 80. One end of the limiting rod 84 away from the ring 82 penetrates through the limiting hole 85, and the surface of the limiting rod 84 abuts against the inner wall of the limiting hole 85. A first spring 87 is fixed on the surface of the limiting rod 84. One end of the first spring 87 away from the limiting rod 84 is fixed on the inner wall of the cavity 81. A limiting block 86 is fixed on the surface of the limiting rod 84. The connecting assembly 8 further includes a linkage member 88. The fixed cylinder 5 is sleeved on the surface of the inlet 3. The inclined surface of the limiting block 86 abuts against the surface of the fixed cylinder 5. The limiting block 86 drives the limiting rod 84 to move, and then abuts against the inner wall of the contact hole 83. The ring 82 rotates, and the first spring 87 is compressed. When the limiting rod 84 and the limiting block 86 enter the L-shaped groove 11, the first spring 87 is released. The reverse rotation of the ring 82 drives the limiting rod 84 and the limiting block 86 to completely enter the L-shaped groove 11. The side of the limiting block 86 away from the inclined surface abuts against the inner wall of the L-shaped groove 11, stably fixing the fixed cylinder 5 and the fixed disk 80, which is convenient for personnel to install.

[0025] The linkage member 88 includes a bottom plate 880 fixed on the surface of the fixed disk 80. A gear 881 is rotatably connected to the surface of the bottom plate 880. A tooth 882 is fixed on the surface of the ring 82. The gear 881 meshes with the tooth 882. A connection hole 883 is formed on the surface of the fixed disk 80. One end of the tooth 882 away from the ring 82 penetrates through the connection hole 883. A latch rod 885 is arranged on the surface of the bottom plate 880. The latch rod 885 penetrates through the bottom plate 880 and is slidably connected to the bottom plate 880. A second spring 886 is fixed on the surface of the latch rod 885. One end of the second spring 886 away from the latch rod 885 is fixed on the surface of the bottom plate 880. A slot 884 is formed on the surface of the gear 881. The latch rod 885 enters the slot 884 to limit the gear 881, which can prevent accidental contact with the gear 881, resulting in the rotation of the ring 82 and the separation of the fixed disk 80 and the fixed cylinder 5. When disassembly is required, the gear 881 is rotated, the tooth 882 moves, the tooth 882 drives the ring 82 to rotate, drives the limiting rod 84 to move in the limiting hole 85 through the contact hole 83, and synchronously drives the limiting block 86 to move, so that the limiting block 86 disengages from the L-shaped groove 11. At this time, the fixed cylinder 5 can be taken out to clean the filter element 7.

[0026] The replacement component 9 includes a support rod 91. The support rod 91 is fixed on the surface of the high-pressure resistant pump body 1. At the top of the support rod 91, an L-shaped pipe 90 is fixed. The L-shaped pipe 90 communicates with the inlet 3. A gate valve 92 is connected to the surface of the L-shaped pipe 90. The new fixing cylinder 5, the filter element 7 and the connection component 8 on the surface of the L-shaped pipe 90 can be docked. Through the thread of the inlet 3, a sealing cover can be used for capping. At this time, the gate valve 92 can be opened, and the L-shaped pipe 90 can perform temporary transportation work, which can avoid affecting the transportation efficiency when cleaning the filter element 7.

[0027] One side of the limiting block 86 away from the center of the fixed disk 80 is set to be inclined. When being touched, the limiting block 86 can drive the limiting rod 84 to move. Threads are provided on the surfaces of the inlet 3 and the L-shaped pipe 90, and a sealing cover can be used for fixing. A sealing ring 10 is fixed inside the fixing cylinder 5. An L-shaped groove 11 is formed on the surface of the fixing cylinder 5. The sealing ring 10 can ensure sealing. The L-shaped groove 11 and the limiting block 86 are mutually limited. Two sets of connection components 8 are provided, and one set of the two sets of connection components 8 away from the inlet 3 is arranged on the surface of the L-shaped pipe 90 and can perform temporary transportation work.

[0028] During installation, pull the clamping rod 885 to disengage it from the clamping groove 884. At this time, sleuth the fixing cylinder 5 on the surface of the inlet 3. At this time, the inclined surface of the limiting block 86 abuts against the surface of the fixing cylinder 5. At this time, the limiting block 86 drives the limiting rod 84 to move, and then abuts against the inner wall of the abutting hole 83. At this time, the ring 82 rotates and the first spring 87 is compressed. When the limiting rod 84 and the limiting block 86 enter the L-shaped groove 11, the first spring 87 is released, and the reverse rotation of the ring 82 drives the limiting rod 84 and the limiting block 86 to completely enter the L-shaped groove 11. At this time, the side of the limiting block 86 away from the inclined surface abuts against the inner wall of the L-shaped groove 11, thereby stabilizing the fixing cylinder 5 and the fixing plate 80, which is convenient for personnel to install. At this time, release the clamping rod 885, and the second spring 886 drives the clamping rod 885 into the clamping groove 884 to limit the gear 881, which can prevent accidental contact with the gear 881, resulting in the rotation of the ring 82 and the disengagement of the fixing plate 80 and the fixing cylinder 5. At the same time, the sealing ring 10 ensures the sealing performance between the inlet 3 and the fixing cylinder 5. At this time, the pipeline can be connected through the flange 6 for use, and the filter element 7 is used for filtration. When replacement is required, separate the pipeline from the flange 6, pull the clamping rod 885 to disengage it from the clamping groove 884, rotate the gear 881 to drive the gear teeth 882 to move. The connecting hole 883 does not prevent the movement of the gear teeth 882. The gear teeth 882 drive the ring 82 to rotate, drive the limiting rod 84 to move in the limiting hole 85 through the abutting hole 83, and synchronously drive the limiting block 86 to move, so that the limiting block 86 disengages from the L-shaped groove 11. At this time, the fixing cylinder 5 can be taken out to clean the filter element 7, which is convenient for personnel to disassemble. At the same time, the personnel can dock the new fixing cylinder 5, the filter element 7 with the connecting component 8 on the surface of the L-shaped pipe 90. Through the thread of the inlet 3, the sealing cover can be used for capping. At this time, the gate valve 92 can be opened, and the L-shaped pipe 90 can carry out temporary transportation work, which can avoid affecting the transportation efficiency when cleaning the filter element 7. When the cleaning is completed, dock the fixing cylinder 5 with the fixing plate 80 and the inlet 3 again, and close the gate valve 92 to continue normal use.

[0029] The above text generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
