Description

Technical Field

[0001] The utility model relates to the technical field of double-suction pumps, in particular to a double-suction pump positioning structure. Background Art

[0002] As an important form of centrifugal pump, double-suction pump is widely used in engineering because of its high head and large flow rate. The impeller of this pump type is actually composed of two back-to-back impellers, and the water flowing out of the impellers merges into a volute. The double-suction pump has the following characteristics: it is equivalent to two single-suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same impeller outer diameter; the pump casing is horizontally opened, which is convenient for inspection and maintenance. At the same time, the inlet and outlet of the double-suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the layout and installation of the pump and the inlet and outlet pipes; the impeller structure of the double-suction pump is symmetrical, there is no axial force, and the operation is relatively stable.

[0003] Most of the existing double-suction pumps are positioned by bolts, which results in the inability to quickly install or disassemble the double-suction pump when necessary, which increases a lot of workload and brings unnecessary trouble to the staff.

[0004] Therefore, there is room for improvement, and the utility model provides a double-suction pump positioning structure. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to propose a double-suction pump positioning structure, and the specific scheme is as follows:

[0006] A double-suction pump positioning structure comprises a base, a motor is installed inside the base, a driving gear is connected to the power drive end of the motor, a screw is connected inside the base, a driven gear is installed at the inner center of the screw, two symmetrical moving seats are connected outside the screw, slide plates are installed on the lower surfaces of the two moving seats, two symmetrical sliding grooves are provided inside the base, a positioning rod is installed on one side of the two moving seats, a connecting groove is provided on the top of the base, a connecting seat is connected inside the connecting groove, positioning grooves are provided on both sides of the outside of the connecting seat, and a double-suction pump device is installed on the top of the connecting seat.

[0007] Furthermore, the connection between the screw rod and the base is movably connected via a bearing, and the two movable seats are both connected to the inside of the base.

[0008] Furthermore, the teeth of the driving gear mesh with the teeth of the driven gear, and the driving gear and the driven gear rotate in opposite directions.

[0009] Therefore, when the motor drives the driving gear to rotate, the driving gear drives the driven gear to rotate, and the driven gear drives the lead screw to rotate.

[0010] Furthermore, the slide plate is located inside the slide groove and is a sliding connection structure.

[0011] Therefore, by arranging the slide plate and the slide groove, the movable seat is located in the base and moves linearly.

[0012] Furthermore, the two movable seats are respectively located at two ends of the connecting seat, and the positioning rod and the positioning groove are adapted to each other.

[0013] Therefore, when the positioning rod is located in the positioning groove, the connecting seat is fixed inside the connecting groove, and at this time, the double-suction pump device is successfully connected to the top of the base.

[0014] Furthermore, the double-suction pump device is located on the top of the base, and the connecting seat and the double-suction pump device are an integrated structure.

[0015] Furthermore, mounting plates are installed on both sides of the outside of the base, and two symmetrical bolts are connected inside the two mounting plates.

[0016] Thus, the mounting plate can be positioned on the ground or other objects by means of several groups of bolts, thereby positioning the double-suction pump device.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] The base is fixed to the ground or other objects by several bolts, and then the double-suction pump device is positioned on the top of the base. When the double-suction pump device needs to be disassembled later, the motor is started until the two moving seats respectively drive the two positioning rods to disengage from the positioning grooves opened on both sides of the connecting seat, and the double-suction pump device can be disassembled separately; this structure is convenient for the staff to quickly install or disassemble the double-suction pump device separately without the need to disassemble the entire device. The operation is simple and convenient, which brings convenience to the staff, improves work efficiency, and achieves the beneficial effect of better fixation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The double-suction pump device 13 is located on the top of the base 1 . The connecting seat 11 and the double-suction pump device 13 are an integrated structure. Mounting plates 14 are installed on both sides of the outside of the base 1 . Two symmetrical bolts 15 are connected to the inside of the two mounting plates 14 .

[0028] The base 1 is fixed to the ground or other objects by setting a plurality of sets of bolts 15, and then the double-suction pump device 13 is positioned and connected to the top of the base 1, and the double-suction pump device 13 can be disassembled and assembled separately later; the movable seat 6 is located inside the base 1 and moves linearly by setting the slide plate 7 and the slide groove 8; the motor 2 rotates forward for a certain period of time and then rotates in the reverse direction (it can be set by programming, which is a well-known technology and will not be described in detail here).

[0029] The implementation process of this embodiment is as follows:

[0030] The base 1 is fixed to the ground or other objects by a number of bolts 15, and then the double-suction pump device 13 is positioned on the top of the base 1. When the double-suction pump device 13 needs to be disassembled later, the user only needs to start the motor 2, and the power drive end of the motor 2 drives the driving gear 3 to rotate. Since the teeth of the driving gear 3 are meshed with the teeth of the driven gear 5, the driving gear 3 drives the driven gear 5 to rotate when it rotates, and the driven gear 5 drives the screw rod 4 to rotate. At this time, the two moving seats 6 are moved to both ends at the same time by the setting of the slide plate 7 and the slide groove 8, and the distance between the two moving seats 6 is expanded until the two moving seats 6 respectively drive the two positioning rods 9 to disengage from the positioning grooves 12 opened on both sides of the connecting seat 11. The user then removes the double-suction pump device 13 from the top of the base 1. When the connecting seat 11 is disengaged from the inside of the connecting groove 10, the double-suction pump device 13 can be disassembled separately at this time.

[0031] When the double-suction pump device 13 is subsequently installed, the connecting seat 11 is located inside the connecting groove 10. After the double-suction pump device 13 is located on the top of the base 1, the user starts the motor 2, and the motor 2 drives the driving gear 3 to rotate. At this time, the driving gear 3 drives the driven gear 5 to rotate in the opposite direction, and the two moving seats 6 gradually move toward the middle until the two moving seats 6 drive the two positioning rods 9 to be located inside the two positioning grooves 12. The connecting seat 11 can be fixed inside the connecting groove 10. At this time, the double-suction pump device 13 can be successfully positioned and connected to the top of the base 1; this structure is convenient for the staff to quickly install or disassemble the double-suction pump device 13 alone, and the operation method is simple and convenient.
