Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pumps, in particular to a double-suction pump that can be installed in any direction. Background Art

[0002] Double suction centrifugal pump has structural symmetry, but this symmetry is not well utilized during installation and use. Traditional centrifugal pumps such as Figure 2 As shown, the non-drive end of the pump shaft is a closed structure, making it impossible to connect to the drive mechanism. If the rotation direction of the produced pump does not meet the user's requirements, the old foundation must be demolished and a new installation foundation must be built, which is very costly and labor-intensive. At the same time, due to the different installation methods, the inventory of pump shafts will also increase, resulting in a waste of resources. Utility Model Content

[0003] The purpose of the utility model is to provide a double-suction pump that can be flexibly installed, so that there is no need to consider the direction of the pump during production, and the waste of resources caused by a fixed and rigid installation mode is avoided.

[0004] To achieve the above-mentioned purpose, the utility model proposes a double-suction pump that can be installed in any direction, including a pump body, a pump shaft and a bearing fastener, wherein the pump shaft is arranged at the center of the pump body; bearing devices are symmetrically provided on the left and right sides of the pump shaft, and the bearing fastener is arranged between the bearing device and the pump shaft, so that both ends of the pump shaft are open drive machine connection ends, =.

[0005] Furthermore, the driving machine connection end is connected to the driving mechanism through the driving end shaft extension.

[0006] Furthermore, the bearing fastener is a locking nut, which is connected to the bearing device and the pump shaft through a retaining washer, and is used to lock the bearing device to prevent axial movement of the rotor component; the retaining washer is used to prevent the locking nut from loosening or falling off during rotation.

[0007] Furthermore, a groove is provided on the pump shaft, a nut groove is provided on the locking nut, and an outer fin and an inner fin are provided on the anti-retraction washer. The outer fin of the anti-retraction washer is inserted into the nut groove of the locking nut, and the inner fin is inserted into the groove of the pump shaft. When the rotation direction does not match the thread rotation direction, it will not affect the locking reliability.

[0008] Furthermore, a protective cover is included. When one end of the pump shaft is connected to the drive mechanism, the other end is covered with the protective cover, which protects against harm to the user.

[0009] Furthermore, the driving mechanism is a motor.

[0010] Compared with the prior art, the advantages of the present invention are:

[0011] 1. The utility model sets both ends of the pump shaft as open connection ends, so that the pump equipment can be installed arbitrarily on site according to user needs, providing users with greater freedom in temporary equipment solutions. Especially when the on-site equipment is compact, the driver can adjust the installation position as needed, realizing flexible installation of the pump body and the drive mechanism, and getting rid of installation limitations.

[0012] 2. The double-suction pump of the present invention has strong versatility. Pump shafts of the same specifications no longer need to be stocked due to the different positions of the driving machine, thereby avoiding the problem of increased pump shaft inventory caused by different installation methods, reducing inventory, avoiding waste, enhancing the flexibility of installation and production, and reducing the error rate.

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be further described below.

[0020] like Figure 2 As shown, the traditional centrifugal pump has a symmetrical structure, but at both ends of the pump shaft, one end is connected to the drive end shaft extension 62, and the other end is the non-drive end end 61, which is a closed structure. As a result, the other end cannot be connected to the drive mechanism. When the steering direction of the produced pump is inconsistent with the user's requirements, the old foundation needs to be blown up and a new installation foundation needs to be made, which is costly, wastes labor, and is very expensive.

[0021] This embodiment provides a double suction pump that can be installed in any direction, such as Figure 1 As shown, it includes a pump body 1, a pump shaft 2 and a bearing fastener 3, wherein the pump shaft 2 is installed at the center of the pump body 1; bearing devices are symmetrically provided on the left and right sides of the pump shaft 2, and the bearing fastener 3 for fastening the bearing device is provided between the bearing device and the pump shaft 2, so that both ends of the pump shaft 2 are open drive connection ends, and the drive connection ends are connected to the drive mechanism through the drive end shaft extension 5. Figure 1 As shown, the drive end shaft extensions 5 on both sides are arranged symmetrically.

[0022] In this embodiment, Figure 3-6 As shown, the bearing fastener 3 is a locking nut 32, which is connected to the bearing assembly 7 and the pump shaft 2 through a retaining washer 31. It is used to lock the bearing assembly 7 to prevent the rotor component from moving axially. The retaining washer 31 is used to prevent the locking nut 32 from loosening or falling off during rotation. The specific connection structure is as follows: a groove 21 is formed on the pump shaft 2, and four nut grooves 321 are evenly arranged on the outer ring of the locking nut 32. At the same time, as shown in FIG. Figure 5 As shown, the retaining washer 31 is provided with an outer fin 311 and an inner fin 312, wherein the outer fin 311 is inserted into the nut groove 321 of the locking nut 32, and the inner fin 312 is inserted into the groove 21 of the pump shaft 2. The pump shaft 2 is provided with a shaft thread. During the installation of the equipment, when the rotation direction does not match the rotation direction of the shaft thread, it will not affect the reliability of the locking.

[0023] The rotation direction of the double suction pump in this embodiment is fixed. During the installation process, the position of the driver will be selected according to the user's needs, such as Figure 1 In the figure, the right side of the pump shaft 2 of the double-suction pump is connected to the driving machine through the drive end shaft extension 5, and the left side is covered with a protective cover 4 to avoid dangerous injuries.

[0024] At the same time, the left end of the pump shaft 2 can also be connected to the driving mechanism, and the right end can be covered with a protective cover 4.

[0025] The double suction pump of this embodiment can be installed at any end according to the needs of the user, providing greater freedom for the user's temporary equipment plan. Especially when the on-site equipment is compact, the driver can adjust the installation position as needed.

[0026] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any way. Any person skilled in the art who, without departing from the scope of the present invention, makes any equivalent substitution, modification, or other variation to the technical solution and technical content disclosed herein shall be deemed to fall within the scope of the present invention and remain within the scope of protection of the present invention.
