Description

Technical Field

[0001] This application relates to the field of fluid equipment, and in particular to a vertical coal slurry pump that is easy to install. Background Technology

[0002] A pump is a machine that transports or pressurizes fluids. It transfers the mechanical energy of a prime mover or other external energy to a liquid, increasing the liquid's energy. Pumps are mainly used to transport liquids such as water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids.

[0003] Existing pumps, in terms of installation method, typically include horizontal pumps and vertical pumps. Vertical pumps usually include a pump body and a base for fixing the pump body. The existing vertical pump base is usually fixed at the lower end of the pump body to support the vertical pump. During installation, the position of the base is located through the connection between the pipeline and the pump body, thereby fixing the base and fixing the position of the pump body accordingly.

[0004] However, although vertical pumps are often planned by designers before installation, their location may change during actual construction. Due to the fixed connection between the base and the pump body, the position of the base is often difficult to change after the pump body is connected to the pipeline. If the ground after the vertical pump's location change has conditions that are not conducive to the installation of the base, such as obvious protrusions or pipelines laid on the bottom surface under the base, then a lot of time will often need to be spent dealing with these problems before the vertical pump is installed, which will reduce the installation efficiency of the vertical pump. Summary of the Invention

[0005] To improve the installation efficiency of vertical pumps, this application provides a vertical coal slurry pump that is easy to install.

[0006] The vertical coal slurry pump provided in this application, which is easy to install, adopts the following technical solution: The pump body includes a pump body and an installation assembly. The pump body includes a drive part, a connecting part and a working part arranged in sequence. The installation assembly includes a first mounting base and a second mounting base, which are perpendicular to each other. The working part is disposed on the first mounting base. A connecting assembly is disposed between the second mounting base and the connecting part. The connecting assembly is used to realize the connection between the second mounting base and the connecting part.

[0007] By adopting the above technical solution, the pump body is installed on the first mounting base, and the second mounting base is perpendicularly connected to the first mounting base. This allows the pump body to be installed and fixed by fixing the second mounting base when the pump body needs to be fixed and the first base cannot be installed. The connecting components make the connection between the pump body and the second mounting base more stable, and also ensure that the pump body will not easily fall off when the connection between the first and second mounting bases fails. Compared with the existing structure where the base and the pump body are fixedly connected, this provides a new installation position and method for the pump body. When the installation of the first mounting base is difficult, the pump body can be installed and fixed by fixing the second mounting base, saving time and improving the efficiency of pump body installation.

[0008] Optionally, the connecting assembly includes a connecting seat and a connecting member. The connecting seat is mounted on a second mounting base, and the connecting member includes a hinged fixed half-ring and a movable half-ring. The fixed half-ring is mounted on the connecting seat and abuts against the outer wall of the connecting part. The movable half-ring can abut against the outer wall of the connecting part after rotating around the hinge axis of the fixed half-ring. The end of the fixed half-ring away from the hinge axis and the end of the movable half-ring away from the hinge axis can be connected in a detachable manner.

[0009] By adopting the above technical solution, the movable half-ring can form a closed ring around the fixed half-ring by rotating around the hinge axis between the movable and fixed half-rings, which is fitted outside the pump body connection. The inner walls of both the fixed and movable half-rings can abut against the outer wall of the connection. This makes the connection between the pump body and the second mounting base more stable. Furthermore, the fact that the ends of the fixed half-rings away from the hinge axis and the movable half-rings away from the hinge axis can be detachably connected allows the pump body to be removed from the closed ring formed by the fixed and movable half-rings. This enables the pump body to be removed from the first and second mounting bases for repair by disconnecting the connection between the pump body and the second mounting base when a pump body malfunctions.

[0010] Optionally, the second mounting base is provided with a groove whose extension direction is consistent with the length direction of the pump body, and the connecting base is provided with a sliding part, which slides in conjunction with the groove.

[0011] By adopting the above technical solution, the second mounting base is provided with a sliding groove, and the connecting base is provided with a sliding part that can slide and cooperate with the sliding groove. Therefore, the position of the connecting base on the second mounting base can be adjusted along the length direction of the sliding groove. This allows the position of the connecting base on the second mounting base to be adjusted, so that the fixed half ring and the movable half ring can avoid other parts on the connecting part when connected with the connecting part.

[0012] Optionally, the slide is a C-shaped groove, and a limit bolt is installed on the sliding part by means of thread engagement, and the limit bolt can abut against the bottom surface of the slide.

[0013] By adopting the above technical solution, the slide is a C-shaped groove, and a limit bolt is installed on the sliding part by means of threaded engagement. The limit bolt can abut against the bottom surface of the slide, which allows the operator to fix the position of the sliding part in the slide by tightening the limit bolt.

[0014] Optionally, both the inner walls of the fixed semi-ring and the inner walls of the movable semi-ring are provided with buffers, which are used to abut against the outer wall of the connecting part.

[0015] By adopting the above technical solution, both the inner wall of the fixed half ring and the inner wall of the movable half ring are provided with buffers that can abut against the outer wall of the connecting part. This allows some of the vibration transmitted at the drive part to be absorbed at the connecting part when the pump body is in operation, thereby increasing the stability of the pump body during operation.

[0016] Optionally, the first mounting base includes a fixed base body and a mounting plate. The working part is mounted on the mounting plate. The fixed base body is provided with a mounting groove, and the mounting plate is located in the mounting groove and can slide in the mounting groove. The connecting base includes a sliding base body, a rotating base body, and a connecting rod. The sliding part is disposed on the sliding base body, and the rotating base body is mounted on the sliding base body. One end of the connecting rod is connected to the rotating base body by a threaded engagement, and the other end of the connecting rod is hinged to the fixed half-ring. The rotating base body can rotate around the axis of the connecting rod on the sliding base body.

[0017] By adopting the above technical solution, the first mounting base includes a fixed base body and a mounting plate. The mounting plate can slide relative to the fixed base body along the length direction of the mounting groove on the fixed base body. This allows the position of the mounting plate on the fixed base body to still be adjusted after the fixed base body is fixed. The pump body is connected to the mounting plate, so that while the mounting plate supports the pump body, it can also adjust the installation position of the fixed base body on the ground by driving the fixed base body to slide relative to the mounting plate. The connecting base includes a sliding base body, a rotating base body, and a connecting rod, so that the operator can adjust the extension length of the connecting rod on the rotating base body by driving the rotating base body to rotate around the axis of the connecting rod, thereby realizing the relative sliding between the fixed base body and the mounting plate.

[0018] Optionally, a warm pump assembly is provided on the second mounting base. The warm pump assembly includes a warm pump component, an input pipe, an output pipe, and a telescopic base. The telescopic base includes a fixed part, a movable part, and a spring. The fixed part is installed on the second mounting base, and the spring is located inside the fixed part and connected to the movable part. The movable part is inserted into the fixed part. The end of the movable part away from the spring is connected to the warm pump component. The warm pump component can fit against the outer wall of the working part. A cavity is formed inside the warm pump component, and the input pipe and the output pipe are respectively connected to the cavity.

[0019] By adopting the above technical solution, the telescopic seat allows the warming pump component to adapt to changes in the pump body's position on the first mounting seat. The spring ensures that the warming pump component remains in contact with the working part. When warming up is required, hot oil is introduced into the cavity of the warming pump component through the input pipe, thereby increasing the temperature of the warming pump component. Since the warming pump component is in contact with the outer wall of the working part, the temperature inside the warming pump component can be transferred to the working part, thus allowing the pump body components in the working part to be preheated. This reduces the probability of the pump body components suddenly expanding due to the high temperature of the coal slurry during subsequent operation, which could cause the pump body components to jam. The output pipe allows the hot oil in the cavity to flow back, avoiding oil waste.

[0020] Optionally, a condenser is provided on the second mounting base, and a cooling section is provided on the output pipe, with the output pipe passing through the condenser. A cooling cover is also provided on the second mounting base, covering the outside of the drive unit, and the cooling section is installed on the inner wall of the cooling cover.

[0021] By adopting the above technical solution, a condenser is provided on the second mounting base, and the output pipe passes through the condenser. This allows the hot oil passing through the output pipe to be cooled by the condenser and then flow into the cooling section. The cooling section is installed on the inner wall of the cooling cover, which allows the cooled oil to pass through the cooling cover to cool down the running drive unit before flowing back.

[0022] In summary, this application includes at least the following beneficial technical effects: 1. By setting a second mounting base on the first mounting base, the pump body can be fixed not only by the first mounting base but also by the second mounting base during installation. This provides a new installation position and method for the pump body. When the installation of the first mounting base is difficult, the pump body can be fixed by fixing the second mounting base, saving time and improving the efficiency of pump body installation.

[0023] 2. By setting buffers on the inner walls of the fixed half-ring and the movable half-ring that can abut against the outer wall of the connecting part, the vibration transmitted at the drive part can be partially absorbed at the connecting part when the pump body is in operation, thereby increasing the stability of the pump body operation.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. Example

[0027] This application discloses a vertical coal slurry pump that is easy to install, referring to... Figure 1 and Figure 2 The pump body 1 includes a pump body 1 and an installation assembly 2. The pump body 1 is a vertical coal slurry pump. From top to bottom, the pump body 1 consists of a drive part 3, a connecting part 4, and a working part 5. The installation assembly 2 includes a first mounting base 6 and a second mounting base 7. The working part 5 of the pump body 1 is mounted on the upper surface of the first mounting base 6, and the second mounting base 7 is also vertically fixed to the upper surface of the first mounting base 6. A connecting assembly 8 is provided between the second mounting base 7 and the connecting part 4 of the pump body 1 to realize the connection between the second mounting base 7 and the pump body 1.

[0028] Reference Figure 1 , Figure 2 and Figure 3The connecting assembly 8 includes a connecting seat 9 and a connecting member 10. The connecting seat 9 is mounted on the second mounting seat 7, and the end of the mounting seat away from the second mounting seat 7 is connected to the connecting member 10. The connecting member 10 includes a fixed half ring 11 and a movable half ring 12. One end of the fixed half ring 11 is hinged to one end of the movable half ring 12. This allows the movable half ring 12 to rotate around the hinge axis with the fixed half ring 11, forming a closed loop around the connecting part 4. To facilitate the removal of the pump body 1 from between the movable half ring 12 and the fixed half ring 11, the ends of the fixed half ring 11 and the movable half ring 12 away from the hinge axis are connected by bolts. This allows the pump body 1 to be removed from the second mounting seat 7 by driving the movable half ring 12 to rotate around the hinge axis when it is necessary to disassemble the pump body 1 on the first mounting seat 6.

[0029] Reference Figure 2 , Figure 3 and Figure 4 Furthermore, buffer members 15 are respectively provided on the inner wall of the fixed half ring 11 and the inner wall of the movable half ring 12. The buffer members 15 are made of high temperature resistant rubber. This allows the buffer members 15 to abut against the outer wall of the connecting part 4 when the fixed half ring 11 and the movable half ring 12 form a closed ring and are fitted onto the outer wall of the connecting part 4. This allows the vibration transmitted at the drive part 3 to be partially absorbed at the connecting part 4 when the pump body 1 is in operation, thereby increasing the operational stability of the pump body 1.

[0030] Reference Figure 1 , Figure 2 and Figure 4 A groove 13 extending in the same direction as the length of the pump body 1 is provided on the second mounting base 7. The groove 13 is a C-shaped groove. A sliding part 14 is provided on the connecting base 9. The sliding part 14 slides in conjunction with the groove 13. This allows the sliding base to slide along the length of the groove 13 on the second mounting base 7. This allows the positions of the fixed half ring 11 and the movable half ring 12 on the connecting part 4 to be adjusted. This allows the fixed half ring 11 and the movable half ring 12 to avoid related components on the outer wall of the connecting part, reducing the probability of interference when the fixed half ring 11 and the movable half ring 12 are connected to the connecting part 4.

[0031] In order to fix the position of the sliding part 14 in the slide groove 13, a limiting bolt 22 is vertically inserted through the sliding part 14. The limiting bolt 22 is connected to the sliding part 14 by thread engagement. This allows the operator to fix the position of the sliding part 14 in the slide groove 13 by tightening the limiting bolt 22 after the sliding part 14 slides to the appropriate position in the slide groove 13, thereby fixing the position of the support seat on the second mounting seat 7.

[0032] Reference Figure 1 , Figure 2 and Figure 4 The first mounting base 6 includes a fixed base 16 and a mounting plate 17. The fixed base 16 is provided with a mounting groove 18 extending perpendicularly to the surface of the second mounting base 7. The mounting plate 17 is slidably disposed within the mounting groove 18. The working part 5 of the pump body 1 is mounted on the mounting plate 17. This allows the fixed base 16 to slide relative to the mounting plate 17 after the pump body 1 is connected to the pipeline, thereby achieving position adjustment. To facilitate the operator in driving the fixed base 16 to slide relative to the mounting plate 17, the connecting base 9 includes a sliding base 19, a rotating base 20, and a connecting rod 21. A sliding part 14 adapted to the sliding groove 13 is disposed on the sliding base 19, while the rotating base 20 is... The rotating connection is located on the side of the sliding seat 19 away from the slide groove 13. One end of the connecting rod 21 is connected to the rotating seat 20 by a threaded connection, and the other end of the connecting rod 21 is fixedly connected to the fixed half ring 11. The rotating seat 20 can rotate around the axis of the connecting rod 21 on the sliding seat 19. This allows the operator to adjust the extension length of the connecting rod 21 on the rotating seat 20 by driving the rotating seat 20 to rotate around the axis of the connecting rod 21. This allows the fixed half ring 11 to drive the pump body 1 to change its position on the first mounting seat 6, thereby driving the fixed seat 16 to change its position relative to the mounting plate 17, thus increasing the installation range of the first mounting seat 6.

[0033] A nut is also provided on the connecting rod 21, which prevents the rotating seat from rotating around the axis of the connecting rod 21 when the nut is tightened and abuts against the rotating seat 20, thereby fixing the extension length of the connecting rod 21 on the rotating seat 20.

[0034] Reference Figure 1 , Figure 2 and Figure 4A warming pump assembly 23 is provided on the second mounting base 7. The warming pump assembly 23 includes a warming pump component 24, an input pipe 25, an output pipe 26, and a telescopic seat 27. The input pipe 25 and the output pipe 26 are both high-temperature resistant hoses. The telescopic seat 27 includes a fixed part 29, a movable part 30, and a spring 31. The fixed part 29 is vertically fixed to the surface of the second mounting base 7, while the movable part 30 is fixedly connected to the warming pump component 24. The spring 31 is installed inside the fixed part 29. One end of the movable part 30 is inserted into the fixed part 29 and connected to the spring 31. The other end of the movable part 30 is connected to the warming pump component 24. This allows the position of the warming pump component 24 on the second mounting base 7 to change along with the position of the pump body 1 on the first mounting base 6 when the position of the pump body 1 changes. The spring 31 ensures that the warming pump component 24 is always in contact with the outer surface of the working part 5 on the pump body 1.

[0035] A cavity 28 is provided inside the warming pump component 24. One end of the input pipe 25 is connected to the external hot oil supply system, and the other end of the input pipe 25 is connected to the cavity 28 of the warming pump component 24. One end of the output pipe 26 is also connected to the cavity 28, and the other end of the output pipe 26 is connected to the external return oil circuit. This allows external hot oil to enter the cavity 28 through the input pipe 25, thereby raising the temperature of the warming pump component 24. After the temperature of the warming pump component 24 rises, it will transfer heat to the working part 5, causing the temperature of the components of the pump body 1 in the working part 5 to rise as well, thus achieving the effect of warming the pump. This prevents the pump body 1 from easily malfunctioning when transporting coal slurry.

[0036] A condenser 32 is also provided on the second mounting base 7, and the output pipe 26 passes through the condenser 32. This allows the condenser 32 to cool the oil in the output pipe 26. A cooling cover 34 is installed on the second mounting base 7 at the position corresponding to the drive unit 3, covering the drive unit 3. A cooling unit 33 is provided on the output pipe 26 and is installed on the inner wall of the cooling cover 34. This allows the oil to be cooled by the condenser 32 when it flows from the cavity 28 to the output pipe 26 for return. The cooled oil then flows into the cooling unit 33 to cool the drive unit 3 of the pump body 1 before returning.

[0037] The implementation principle of this application embodiment is as follows: First, connect the inlet and outlet pipes on the pump body 1 to the relevant equipment. Then, depending on the actual situation, if there are pipes or other unsuitable conditions on the ground for fixing the first mounting base 6, the fixing base 16 of the first mounting base 6 can be offset relative to the mounting plate 17 by rotating the rotating base 20. This allows the fixing base 16 to bypass pipes or protrusions on the ground, and finally, the pump body 1 is fixed by fixing the fixing base 16 and fixing the connecting rod 21 extending its length on the rotating base 20. If the first mounting base... If installation still fails, then look for a suitable location for a second mounting bracket 7 in the surrounding environment. Use the second mounting bracket 7 to install and secure the pump body 1. After the pump body 1 is secured, hot oil is supplied through the input pipe 25 to the cavity 28 of the warming pump component 24. This allows the warming pump component 24 to preheat the working part 5 of the pump body 1. While preheating, the pump body 1 is started and allowed to run slowly, ensuring that the components of the pump body 1 located in the working part 5 are heated evenly during the warm-up process. Once the working part 5 has been preheated to a certain temperature, the pump body 1 can be put into operation.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
