DETAILED DESCRIPTION

[0016] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0017] A split pump pressure box for an air cooler, such as Figure 1-12As shown, it includes a detachable enclosure structure 1, which includes two oppositely arranged vertical enclosures 2, a top enclosure 3 arranged on the top of the two vertical enclosures 2, and the two vertical enclosures 2 are installed on the bottom enclosure 4, so that the vertical enclosure 2, the top enclosure 3, and the bottom enclosure 4 form a rectangular cylindrical structure, and a pump pressure inner cavity 5 with two ends passing through is formed inside the rectangular cylindrical structure. When actually used, the enclosure structure 1 has two forms, including a storage state and a pressure state. When not in use, the bottom enclosure 4 can be , the top plate enclosure 3, and the vertical plate enclosure 2 are stacked in sequence to form a small space for stacking, forming a pump pressure box that is easy to store and place; when it is necessary to perform a pressure test on the heat exchange tube bundle of the air cooler 6, the tooling can be assembled, and the tooling cooperates with the tube sheet flanges at both ends of the air cooler 6 to form a sealed pump pressure cavity 5 outside the heat exchange tube bundle, and an inlet flange 16 and an outlet flange 17 are provided on at least one side of the vertical plate enclosure 2, and the inlet flange 16 and the outlet flange 17 are both connected to the pump pressure cavity 5. In actual use, a water pipe is connected to the inlet flange 16 and the outlet flange 17, and water is injected and exhausted, and the liquid used for pressure is filled into the pump pressure cavity 5, and then the pressure is gradually increased. Pressure accessories such as a pressure gauge, a safety valve, etc. can be provided to monitor the pressure during the pressure test. After the pressure is applied, the pump pressure box can be disassembled for storage, thus avoiding the drawbacks of the overall pump pressure box in the prior art that it cannot be carried and can be used once, reducing material waste and being easy to use.

[0018] Specifically, the pump pressure cavity 5 is used to place an air cooler 6 for sealing test, such as Figure 6-9 As shown, one end of the air cooler 6 is a cooler big end tube sheet 9, and the other end is a cooler small end tube sheet 10, and the openings at both ends of the pump pressure inner cavity 5 respectively form a big end flange 7 and a small end flange 8, the big end flange 7 is for the cooler big end tube sheet 9 to be installed and forms a seal for one end opening of the pump pressure inner cavity 5, and the small end flange 8 is for the cooler small end tube sheet 10 to be installed and forms a seal for the other end opening of the pump pressure inner cavity 5.

[0019] like Fig.11 As shown, on the side of the tube sheet 9 at the big end of the cooler, during installation, the side tube sheet cooperates with the big end flange 7 of the enclosure structure 1, and by placing a cooler sealing gasket 21 between the two and tightening it with bolts, the pump pressure cavity 5 at this end can be sealed.

[0020] The small end clamping flange 11 is also included to seal and install the small end tube sheet 10 and the small end flange 8 of the cooler at the same time. The small end clamping flange 11 is in a rectangular ring shape, such as Figure 3As shown, the small head end clamping flange 11 is provided with an inner flange hole 12 and an outer flange hole 13, the inner flange hole 12 matches with the small head tube sheet flange hole 14 on the edge of the cooler small head end tube sheet 10, and the outer flange hole 13 matches with the small head flange hole 15 on the small head end flange 8. Fig.12 As shown, the cooler sealing gasket 21 set at this end is also in the same shape as the small head end compression flange 11, with holes that match the inner and outer two circles of flange holes. The cooler sealing gasket at this end has a certain width, so that it overlaps the cooler small head end tube sheet 10 and the small head end flange 8 at the same time, and then the small head end compression flange 11 is pressed on the outside, and finally two circles of bolts are installed to lock, so as to achieve the sealing of the pump pressure cavity 5 at this end. It can be understood that after installation, the openings at both ends of the heat exchange tube bundle of the air cooler 6 are open to the air. When the pump pressure cavity 5 is pressurized, if a pipeline of a heat exchange tube bundle leaks, liquid will flow out of the pipe mouth of the pipeline, which is very easy to identify, and then repair measures can be taken to block the leaking heat exchange tube, or the heat exchange tube can be cut, replaced or repaired at a convenient location.

[0021] Furthermore, in order to facilitate the disassembly and assembly of the pump pressure box tooling, Figure 2 As shown, the large end flange 7 and the small end flange 8 are divided into four strip flanges 18, which are respectively arranged at the positions of the vertical plate enclosure 2, the top plate enclosure 3, and the bottom plate enclosure 4 toward the opening sides at both ends, and the four strip flanges 18 surround the openings at both ends of the pump pressure inner cavity 5. The strip flanges 18 respectively surround the large end flange 7 and the small end flange 8 as the enclosure structure 1 is formed. The vertical plate enclosure 2 and the top plate enclosure 3 and the bottom plate enclosure 4 are flange-connected by connecting flanges 19. Box sealing gaskets 20 are arranged between the connecting flanges 19, and bolts are inserted into the connecting flanges 19 after alignment to tighten and seal to form a whole.

[0022] Furthermore, the vertical plate enclosure 2, the top plate enclosure 3, and the bottom plate enclosure 4 are all provided with horizontally and vertically staggered reinforcing ribs 22. In actual use, the reinforcing ribs 22 can be welded vertically on the outer surfaces of the vertical plate enclosure 2, the top plate enclosure 3, and the bottom plate enclosure 4 using thick flat steel, such as Figure 2 , 4 5, a crisscross flat steel is welded on the surface as a reinforcing rib 22;

[0023] In another embodiment, angle iron can be used as the reinforcing rib 22, such as Figure 1 , 6 As shown in , 7, 8, and 9, the reinforcing ribs 22 are formed by criss-cross welding of angle steels.

[0024] A method for using a 6-piece pump pressure box for an air cooler comprises the following steps: Step 1, place the bottom plate coaming 4 on the horizontal deck surface and fix it, the two long sides of the rectangular bottom plate coaming 4 form connecting flanges 19, the two short sides form strip flanges 18, and the heat exchange tube bundle of the air cooler 6 to be pressure tested is placed in the middle of the bottom plate coaming 4; Step 2, assemble the vertical panel 2, place the two vertical panel 2 perpendicular to the long sides of the bottom panel 4, align the connecting flange 19 of the lower edge of the vertical panel 2 with the connecting flange 19 of the bottom panel 4, and set a box sealing gasket 20 between the two connecting flanges 19, and penetrate bolts on the leveling flange to seal the connection between the vertical panel 2 and the bottom panel 4; Step 3, assemble the top plate enclosure 3, align the connecting flanges 19 on both sides of the long sides of the top plate enclosure 3 with the connecting flanges 19 on the upper side of the vertical plate enclosure 2, install the box sealing gasket 20 between the two, and then penetrate and fix them with bolts to form a rectangular cylindrical structure surrounding the heat exchange tube bundle of the air cooler 6, and form rectangular openings at both ends, and strip flanges 18 are arranged around the rectangular opening to form a large end flange 7 and a small end flange 8; Step 4, a rectangular annular cooler sealing gasket 21 is arranged between the cooler big end tube sheet 9 and the big end flange 7. The cooler sealing gasket 21 at this end is pre-installed in place before the heat exchange tube bundle is placed on the bottom plate enclosure 4 in step 1. The flange hole on the big end tube sheet is adjusted to be aligned with the flange hole on the big end flange 7 and fixed with bolts to seal one end of the rectangular cylindrical structure. Step 5, the other end of the rectangular cylindrical structure is open, the small head end flange 8 is flush with the cooler small head end tube sheet 10, and the small head end clamping flange 11 is used to seal the end, and a cooler sealing gasket 21 is arranged between the lower head end clamping flange and the small head end flange 8 and the cooler small head end tube sheet 10, so that the inner ring flange hole 12 is aligned with the flange hole of the cooler small head end and fixed with bolts, and the outer ring flange hole 13 is aligned with the small head flange hole 15 of the small head end flange 8 and fixed with bolts; Step 6, connect the water inlet flange 16 and the water outlet flange 17 to the pump pressure pipeline, inject test water into the pump pressure cavity 5, then increase the pressure of the pump pressure cavity 5 to the test pressure through the water inlet flange port and the water outlet flange port, and observe whether the heat exchange tube bundle has leakage from the cooler small end tube sheet 10.
