Description

Technical Field

[0001] The present application relates to the technical field of liquid delivery pumps, and in particular to a canned pump that is easy to install. Background Art

[0002] The canned pump is a sealless pump. The pump and the drive motor are sealed in a pressure vessel filled with the pumped medium. The pressure vessel has only static seals and a wire group to provide a rotating magnetic field and drive the rotor. This structure eliminates the rotating shaft sealing device of the traditional centrifugal pump, so it can be completely leak-free.

[0003] The installation of the shielded pump in the related art usually requires workers to carry the pump body to the installation site, and then repeatedly move the pump body to align the threaded holes on the base of the pump body with the threaded holes reserved at the installation location, and then insert bolts to fix them, thereby completing the installation. However, in the process of finding the threaded holes in the above process, workers need to repeatedly push the pump body, and the pump body is usually heavy, which is not only time-consuming and laborious to push, but also may cause the pump body to squeeze the worker's arm and cause injury to the worker if it is not operated properly.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1 -Attached Figure 2 , further details of this application are given.

[0027] The embodiment of the present application is: a canned pump that is easy to install, referring to Figure 1 , including a shielded pump body 1, the lower end of the shielded pump body 1 is fixedly connected to a base 2, the base 2 is set in a rectangular shape, and there are four threaded holes 21 on the end surface of the base 2, and a positioning pin 3 is slidably inserted in each threaded hole 21,

[0028] The base 2 is provided with a mounting frame 4 around it, the mounting frame 4 is in a square frame shape, and the base 2 is placed in the mounting frame 4. The four corners of the lower end of the mounting frame 4 are rotatably connected with universal wheels 41. Abutment plates 5 are provided on both sides of the lower end of the base 2, the abutment plates 5 are arranged along the width direction of the mounting frame 4, the abutment plates 5 are slidably connected in the mounting frame 4, and the ends of the abutment plates 5 abut against the inner wall of the mounting frame 4.

[0029] Reference Figure 1 and Figure 2The cross-section of the abutment plate 5 is set to be L-shaped, and the sides of the two abutment plates 5 that are close to each other are set to be tilted downward. The upper end side walls of the lower tilted parts of the two abutment plates 5 are rotatably connected with multiple abutment rollers 51, and the outer arc surface of the abutment roller 51 abuts against the lower end surface of the base 2, and the axis of the abutment roller 51 is parallel to the length direction of the mounting frame 4.

[0030] The mounting frame 4 is provided with an adjusting member 6 for adjusting the position of the abutting plate 5 .

[0031] The adjusting member 6 is configured as an adjusting bolt, which corresponds to the abutment plate 5 one by one. The adjusting bolt is threadedly connected to the mounting frame 4 , and the rod of the adjusting bolt passes through the side of the mounting frame 4 and is rotatably connected to the abutment plate 5 .

[0032] Therefore, the adjusting bolt can be rotated to rotate the adjusting bolt, and then the adjusting bolt drives the abutting plate 5 to move to the two sides where the abutting plates 5 are close to each other or away from each other. At the same time, in order to improve the sliding stability of the abutting plates 5, the two abutting plates 5 are fixedly connected to the sides away from each other with guide posts 8. Two guide posts 8 are provided on each abutting plate 5, and the end of the guide post 8 away from the abutting plate 5 passes through the side wall of the installation frame 4 and is slidably connected to the installation frame 4. The axis of the guide post 8 is parallel to the axis of the adjusting bolt and moves synchronously with the adjusting bolt.

[0033] The shielded pump body 1 includes an inlet pipe 11 and an outlet pipe 12 which are fixedly connected and communicated with the pump body. A fixing assembly 7 is provided at the pipe openings of the inlet pipe 11 and the outlet pipe 12. The fixing assembly 7 is used to fix an external hose at the pipe opening of the inlet pipe 11 or the outlet pipe 12.

[0034] The fixing assembly 7 includes a threaded barrel 72 and a fixing ring 71. The threaded barrel 72 is coaxially arranged with the fixing ring 71. The fixing ring 71 is fixedly connected to the arc-shaped outer wall of the water inlet pipe 11 or the water outlet pipe 12. The fixing ring 71 is coaxially arranged with the water inlet pipe 11 and the water outlet pipe 12. The threaded barrel 72 is located on the side of the fixing ring 71 away from the shielded pump body 1. A sealing ring groove 711 is provided on the end surface of the fixing ring 71. A rubber sealing ring 73 is fixedly connected to the end surface of the threaded barrel 72 at one end close to the sealing ring groove 711. The rubber sealing ring 73 is arranged along the end surface of the threaded barrel 72 and the size of the rubber sealing ring 73 matches the size of the sealing ring groove 711.

[0035] Therefore, when the water inlet pipe 11 or the water outlet pipe 12 needs to be connected to an external hose, the hose to be connected to the outlet pipe 12 or the outlet of the water inlet pipe 11 is sleeved on the outlet pipe 12 or the outlet of the water inlet pipe 11, and then the threaded barrel is rotated to make the threaded barrel 72 threadedly connected to the arc-shaped outer wall of the water inlet pipe 11 or the outlet pipe 12, and water is passed so that the rubber sealing ring 73 at the end of the threaded barrel 72 presses the side wall of the hose to be connected tightly against the sealing ring groove 711. Thus, the external hose is fixed to the outlet pipe 12 or the outlet of the water inlet pipe 11.

[0036] The implementation principle of the embodiment of the present application is: when installing the shielded pump, the shielded pump body 1 is placed on the two abutment plates 5, and then the installation frame 4 is moved by the universal wheel 41, and the installation position is adjusted so that the positioning pin 3 is aligned with the threaded hole 21 opened in advance on the ground, and then the positioning pin 3 is inserted into the threaded hole 21 opened on the ground and the positioning pin 3 is kept in the threaded hole 21 on the base 2 at the same time, thereby fixing the installation frame 4.

[0037] Then, by rotating the adjusting bolt, the adjusting bolt drives the two abutment plates 5 to move away from each other, so that the abutment plates 5 gradually disengage from the base 2 until the base 2 completely falls on the ground, the positioning pin 3 is taken out, and the threaded hole 21 opened in the ground and the threaded hole 21 on the base 2 are connected with the same bolt.

[0038] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
