Description

Technical Field

[0001] This invention relates to the field of pump body component technology, specifically to a horizontal corrosion-resistant pump casing. Background Technology

[0002] Horizontal corrosion-resistant pumps are a type of pump that combines a horizontal structure with corrosion resistance. The pump shaft is horizontally mounted, and the motor and pump body are on the same horizontal plane. This results in a low center of gravity, stable operation, and easy installation and maintenance. A key feature is that the flow-through components are made of corrosion-resistant materials, combined with mechanical seals or packing seals, to achieve corrosion-resistant transport. The invention disclosed in CN104302918 A, by opening an inlet and outlet chamber within the casing and connecting these chambers to multiple cavities, effectively improves suction capacity through the combined action of all cavities. Furthermore, by controlling the number of outlet pipes opened, the pressure of the extracted material can be effectively increased. The structure is simple; the inlet and outlet chambers on both sides of the cavity connect all cavities without requiring complex accessories. This solution enhances pumping pressure through the combined operation of multiple cavities. Currently, multi-stage horizontal pumps, for ease of installation and maintenance, use multiple sections connected in the middle of the pump casing. When connecting these sections, a sealing ring is typically placed between them, and the pump body is then assembled and pressed together using a tie rod. The pump's stability depends on the stability of the seal. The sealing ring needs replacement after prolonged use, but current replacement methods require complete disassembly and maintenance, and the sealing effect has certain risks.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Please see the appendix Figure 1-12 This application provides the following technical solutions.

[0018] Example 1: A horizontal corrosion-resistant pump casing includes a pump body 1, on which several pump sections 2 are provided. Each pump section 2 has a mating sealing assembly on one side. The mating sealing assembly includes a combined collar 6 and a corrosion-resistant elastic hollow metal ring 7. One side of the corrosion-resistant elastic hollow metal ring 7 is inserted into an adjacent pump section 2. Each pump section 2 has a mating slot 4 and a mating boss 5 on both sides. The mating slots 4 and mating bosses 5 of two adjacent pump sections 2 are inserted into each other, and a pump joint is provided between the two pump sections 2. A misaligned recessed groove 30 is formed on one side of the pump section 2 at the mating boss 5. The combined collar 6 is fitted onto the mating boss 5, and the side of the combined collar 6 fitted onto the mating boss 5 is inserted into the misaligned recessed groove 30. The outer periphery of the combined collar 6 contacts the inner periphery of the mating slot 4. The corrosion-resistant elastic hollow metal ring 7 is located at the mating slot 4 of the combined collar 6. On one side of the connecting slot 4, an annular extrusion groove 3 is provided, and one side of the corrosion-resistant elastic hollow metal ring 7 is elastically pressed and inserted into the annular extrusion groove 3. The pump body 1 is provided with two pump covers 31, which are respectively connected to two pump sections 2. The two pump covers 31 are respectively provided with connecting slots 4 and connecting bosses 5 that are adapted to the pump sections 2. When the pump cover 31 is connected and combined with the pump section 2, the connecting bosses 5 are inserted into the connecting slots 4, just like when the two pump sections 2 are combined. At the same time, the combined collar 6 drives the corrosion-resistant elastic hollow metal ring 7 to abut against the annular extrusion groove 3 in the connecting slot 4, so as to provide a corrosion-resistant mechanical metal seal at the connection. The combined collar 6 corresponds to the pump joint. When the solution in the pump breaks through the elastic metal extrusion seal of the corrosion-resistant elastic hollow metal ring 7, the combined collar 6 is also needed to seal the pump joint in order to prevent leakage.

[0019] Easy-maintaining sealing components are installed to seal the pump joints. These components are located on both sides of the pump section 2, where they connect to each other. Each component includes a combined sealing ring 12. The combined sealing ring 12 for the joint between two adjacent pump sections 2 includes two arc-shaped frames 13 and two U-shaped sealing strips 14. Sealing grooves 8 are provided on both sides of the pump section 2. Three combined sealing rings 12 are inserted into the two sealing grooves 8 of two adjacent pump sections 2. The U-shaped sealing strips 14 of the combined sealing ring 12 are fitted onto the inner arc surface of the arc-shaped frames 13. A combined joint is provided between the two arc-shaped frames 13 and the two U-shaped sealing strips 14 of the combined sealing ring 12, and the combined joints of the three combined sealing rings 12 are staggered. The two U-shaped sealing strips of one of the combined sealing rings 12... The sealing strip 14 is correspondingly set to the pump joint. Two arc-shaped frames 13 are located on both sides of the combined joint, with two pre-installation positioning blocks 15 and two pre-installation grooves 16 respectively. The two pre-installation positioning blocks 15 are respectively inserted into the two pre-installation grooves 16. After the U-shaped sealing strip 14 of the combined sealing ring 12 is deformed by compression, it can deform and pressurize to seal the combined joint. The misalignment of the joints of the three combined sealing rings 12 can be further elastically deformed and sealed when the U-shaped sealing strip 14 is deformed by compression later. Since one of the combined sealing rings 12 always corresponds to the pump joint, the combined sealing ring 12 can provide a second seal for the pump joint. At the joint position of the pump cover 31 and the pump section 2, while ensuring that the pump joint corresponds to the combined collar 6, the combined sealing ring 12 can be located on the inner circumference of the covering and pressing sleeve 10 and seal the pump joint. One side of each sealing groove 8 is provided with a telescopic annular groove 9. A cover and clamping sleeve 10 is horizontally inserted into each of the two telescopic annular grooves 9. An annular piston 11 is provided on one side of each cover and clamping sleeve 10 located in the telescopic annular groove 9. One side of the cover and clamping sleeve 10 is movably inserted into the sealing groove 8 and is connected to the outer periphery of the combined sealing ring 12. The cover and clamping sleeves 10 of two adjacent pump sections 2 are in contact with each other and have a constraint joint. The constraint joint corresponds to the combined sealing ring 12 in the middle. The side of the cover and clamping sleeve 10 near the combined sealing ring 12 is set with an inner conical surface. When the two cover and clamping sleeves 10 extend out of the telescopic annular groove 9 through the annular piston 11 at the same time, they can contact the outer side of the arc frame 13 through the inner conical surface, thereby pressing and splicing the two arc frames 13 of the combined sealing ring 12, improving the connection and sealing effect between the two. Then, with the compression between the two pump sections 2, the U-shaped sealing strip 14 deforms and fills the sealing groove 8 near the pump joint, achieving efficient sealing.

[0020] Example 2: Based on Example 1, a monitoring component is set up to monitor the water pressure and local temperature in pump section 2, improving the normal operating temperature performance of the pump. The monitoring component is located on one side of pump section 2 and includes a detection module 28. A monitoring threaded mounting groove 17 is vertically opened through one side of pump section 2. A sensor mounting block 29 is threadedly inserted into the monitoring threaded mounting groove 17. A conical groove 19 is opened at the upper end of the monitoring threaded mounting groove 17. A conical sealing sleeve 18 is provided on one side of the sensor mounting block 29 located in the conical groove 19, and the detection module 28 in pump section 2 is inserted into the center of the sensor mounting block 29. A diversion annular groove 20 is opened on one side of the sensor mounting block 29 in pump section 2. The two sides of the diversion annular groove 20 are respectively connected to two telescopic annular grooves 9 with first transition grooves 21. The misaligned recessed groove 30 is located in... A convex ring 22 is provided on one side, and a mating ring groove 23 is opened on one side of the combined collar 6 in the misaligned recessed groove 30. The combined collar 6 is fitted with the convex ring 22 through the mating ring groove 23. A transition annular groove 32 is opened in the convex ring 22. A second transition groove 24 is opened between the transition annular groove 32 and the diversion annular groove 20. Several connecting holes 33 are opened in the combined collar 6 to connect the mating ring groove 23 and the corrosion-resistant elastic hollow metal ring 7. When high-pressure gas is sent into the diversion annular groove 20, the high-pressure gas enters the telescopic annular groove 9 and the corrosion-resistant elastic hollow metal ring 7 through the first transition groove 21 and the second transition groove 24 respectively. This achieves stable fitting constraint of the covering and pressing sleeve 10 on the combined sealing ring 12 and micro-elastic deformation of the corrosion-resistant elastic hollow metal ring 7, thereby improving the metal sealing quality of the corrosion-resistant elastic hollow metal ring 7 inserted into the corrosion-resistant elastic hollow metal ring 7.

[0021] The sensor mounting block 29 is provided with a positioning plate 25 on one side outside the pump section 2. An anti-loosening hole is opened on one side of the positioning plate 25. A valve interface is opened through the pump section 2 in the diversion annular groove 20. An air supply connector 26 is threaded into the valve interface. The upper end of the air supply connector 26 passes through the anti-loosening hole of the positioning plate 25 and is fitted with a one-way valve 27. The air supply connector 26, together with the one-way valve 27, can supply high-pressure gas into the diversion annular groove 20. At the same time, it can constrain the stability of the sensor mounting block 29 inserted into the pump section 2 to prevent loosening. When the pump section 2 does not need to install the detection module 28, the sensor mounting block 29 without the detection module 28 and the air supply connector 26 can be directly installed and connected for use.
