Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a quick-clamping device for pipelines of a water pump test bench. Background Art

[0002] After assembly, the water pump needs to be tested on a test bench for performance. At present, the existing water pump test bench pipeline is connected to the water pump pipeline through a flexible joint. Connecting flanges are set at both ends of the flexible joint. One of the connecting flanges is fixedly connected to the flange of the water pump test bench pipeline, and the other flange is connected to the flange on the water pump pipeline and fastened with hexagonal bolts. Every time the water pump is disassembled and installed, the bolts on the flange need to be disassembled and installed, resulting in a waste of manpower and time, resulting in low testing efficiency, and when testing pumps of different pressure levels, the flexible joints of the corresponding pressure levels need to be replaced. On the one hand, the flexible joint itself increases the cost, and on the other hand, replacing the joint also increases the labor cost. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a quick clamping device for the pipeline of a water pump test bench in view of the deficiencies of the above-mentioned prior art.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A quick clamping device for the pipeline of a water pump test bench includes a connector 1 and a connector 2. The surfaces of the connector 1 and the connector 2 are both connected with clamping claws. The end of the connector 1 is connected to a screw seat with the same appearance as the connector 1, and a threaded hole is processed in the middle of the screw seat. The middle of the connector 2 is processed with a connecting hole for accommodating the connector 1. The ends of the connector 2 are connected to a sealing plate, and the sealing plate is threaded with a bolt, and the bolt is connected to the threaded hole of the screw seat.

[0006] Furthermore, the connector 1 adopts square tube 1, the screw seat is connected to the end of square tube 1, the connector 2 adopts square tube 2, the inner hole of square tube 2 matches the shape of square tube 1, and the sealing plate is connected to the end of square tube 2.

[0007] Furthermore, pads are connected to the inner sides of the clamping jaws of the connecting member 1 and the connecting member 2.

[0008] Compared with the prior art, the quick clamping device for the pipeline of a water pump test bench of the utility model has the following beneficial effects:

[0009] 1. By using a quick clamping device to replace the original bolt connection between flanges, the time for disassembling and installing the pump on the test bench is saved, and the test efficiency is improved;

[0010] 2. Improve the versatility of the test bench pipeline. Since the flanges are clamped together using a quick clamping device, no bolt connection is required. This allows the same pair of flexible joints to be used when testing pumps with flanges of different pressure levels, such as PN6, PN20, PN16, and PN25.

[0011] 3. Save costs. The use of quick clamping device can greatly reduce the labor and time costs of disassembling and assembling flange connection bolts. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below.

[0016] like Figure 1 As shown, a quick clamping device for the pipeline of a water pump test bench includes a connector 1 and a connector 2. The surfaces of the connector 1 and the connector 2 are both connected with a clamping claw 3. The end of the connector 1 is connected to a screw seat 4 with the same appearance as the connector 1, and a threaded hole is processed in the middle of the screw seat 4. The middle of the connector 2 is processed with a connecting hole for accommodating the connector 1. The end of the connector 2 is connected to a sealing plate 5, and the sealing plate 5 is threaded with a bolt 6, and the bolt 6 is connected to the threaded hole of the screw seat 4.

[0017] In this embodiment, connector 1 adopts square tube 1, the shape of screw seat 4 is the same as that of square tube 1, screw seat 4 is connected to the end of square tube 1, connector 2 adopts square tube 2, the inner hole of square tube 2 matches the shape of square tube 1, square tube 1 can be inserted into square tube 2, sealing plate 5 is connected to the end of square tube 2, and threaded connection holes connected to bolts are processed on sealing plate 5. The inner side surfaces of the clamping jaws 3 of connector 1 and connector 2 are connected with pads 7, and pads 7 increase the contact area between the clamping jaws and the flange.

[0018] like Figure 2The figure shows the usage status of the quick clamping device, in which one end of the flexible joint is fixedly connected to the flange of the water pump test bench pipeline, and the connector flange 8 at the other end of the flexible joint is connected to the pump flange 9. The connector flange 8 and the pump flange 9 are clamped by the quick clamping device. When in use, the two claws 3 are placed on the back of the flange, and the bolts 6 are tightened with the pneumatic socket wrench. During the tightening of the bolts, the connector 1 enters the connector 2 2, thereby driving the claws to press the flange inward. In the above manner, the pump flange and the connector flange on the flexible joint can be quickly clamped. Generally, a set of flanges requires 2 to 3 sets of quick clamping devices. After using the quick clamping device, the same pair of flexible joints can be used when testing pumps with flanges of different pressure levels such as PN6, PN20, PN16, and PN25, saving the time of disassembling and installing the pump on the test bench and improving the test efficiency.

Those skilled in the art may make some modifications or changes without departing from the spirit or scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
