Description

Technical Field

[0001] This utility model relates to the field of rotor pump technology, and in particular to a high-efficiency sealed two-blade wide-side rotor pump. Background Technology

[0002] With the development of industry, the demand for liquid conveying equipment is increasing. Rotary pumps have gradually gained attention due to their unique structure and performance. As a type of rotary pump, the two-lobe wide-side rotary pump has gradually formed the efficient, stable, and widely applicable pump products we know today through continuous optimization and improvement.

[0003] Before installation, existing rotor pump end covers usually have a sealing gasket installed on the side of the end cover closest to the rotor pump cavity. However, the sealing gasket is mostly fixed and cannot be adjusted according to the distance between the cavity and the end cover, which reduces the sealing performance between the two. This not only causes liquid leakage but also reduces the pumping efficiency of the rotor pump. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where it is inconvenient to adjust the position of the sealing gasket during end cover installation, thereby reducing the sealing performance between the end cover and the rotor pump cavity. Therefore, this invention proposes a high-efficiency sealing type two-blade wide-side rotor pump.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency sealed two-lobe wide-side rotor pump includes a rotor pump body and an end cover detachably connected to the rotor pump body. It further includes: a threaded sleeve fixedly installed on the end cover, with a lead screw threadedly connected to the threaded sleeve; a sealing gasket disposed between the rotor pump body and the end cover, the sealing gasket having the same shape as the cavity of the rotor pump body, wherein a positioning ring is fixedly connected to the sealing gasket, the positioning ring extending along the length direction of the sealing gasket, and the lead screw rotatably engaging with the positioning ring; and a fixing block fixedly installed on the rotor pump body, the fixing block being provided with a locking element.

[0007] To enable quick installation and removal of the end cap, preferably, the locking component includes: a locking block fixedly installed on the end cap; and a clamping handle rotatably connected to the fixing block, wherein a hook is rotatably connected to the clamping handle and the hook is engaged with the locking block.

[0008] To improve the stability of the end cover installation, preferably, a magnetic frame is fixedly connected to the end cover, and a magnetic groove that cooperates with the magnetic frame is opened on the rotor pump body.

[0009] For mounting the rotor pump body, preferably, a base is fixedly mounted on the rotor pump body, and the base has mounting holes.

[0010] To improve the sealing performance of the connection between the feed pipe and the discharge pipe and the external pipeline, preferably, the feed pipe and the discharge pipe are fixedly connected to the main body of the rotor pump, and flanges are fixedly fitted on both the feed pipe and the discharge pipe, with sealing rings installed inside the flanges.

[0011] To facilitate the adjustment of the sealing gasket position by the staff, preferably, a torsion block is fixedly connected to the end of the lead screw away from the end cover, and the torsion block is provided with anti-slip texture.

[0012] Compared with the prior art, this utility model provides a high-efficiency sealed two-lobe wide-side rotor pump, which has the following beneficial effects:

[0013] 1. This high-efficiency sealed two-lobe wide-side rotor pump can lock and fix the end cover by setting a locking device. The locking method also facilitates the disassembly of the end cover, thereby improving the maintenance efficiency of the rotor pump body by the staff.

[0014] 2. This high-efficiency sealed two-lobe wide-side rotor pump, through the combination of a magnetic suction frame and a magnetic suction groove, can limit the end cover, thereby improving the end cover installation efficiency.

[0015] The parts of this device not described herein are the same as or can be implemented using existing technology. This utility model can adjust the distance between the main body cavity of the rotor pump and the end cover by rotating the lead screw to move the sealing gasket. Furthermore, by using a sealing gasket with the same shape as the main body cavity of the rotor pump, the sealing performance of the end cover installation can be improved.

[0025] Example:

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A high-efficiency sealed two-lobe wide-side rotor pump includes a rotor pump body 1 and an end cover 2 detachably connected to the rotor pump body 1. It also includes: a threaded sleeve 4 fixedly installed on the end cover 2, with a lead screw 5 threadedly connected to the threaded sleeve 4; a sealing gasket 7 disposed between the rotor pump body 1 and the end cover 2, the sealing gasket 7 having the same shape as the cavity of the rotor pump body 1; a positioning ring 6 fixedly connected to the sealing gasket 7, the positioning ring 6 having a long annular support frame with at least four supporting ribs extending distally at the center of the frame; the positioning ring 6 extending along the length of the sealing gasket 7; and a rotatable engagement between the lead screw 5 and the positioning ring 6; and a fixing block 301 fixedly installed on the rotor pump body 1, with a locking element 3 provided on the fixing block 301.

[0027] Specifically, by rotating the lead screw 5 to move the sealing gasket 7, the distance between the cavity of the rotor pump body 1 and the end cover 2 can be adjusted. Furthermore, by using the sealing gasket 7, which has the same shape as the cavity of the rotor pump body 1, the sealing performance of the end cover 2 can be improved. At the same time, the positioning ring 6 can increase the support area with the sealing gasket 7, so that when the sealing gasket 7 is adjusted, it can be moved as a whole to ensure the reliability of the seal.

[0028] The locking component 3 includes: a locking block 302 fixedly installed on the end cover 2, and a pressing handle 303 rotatably connected to the fixing block 301 via a rotating shaft. A hook 304 is rotatably connected to the pressing handle 303 via a shaft pin, and the hook 304 is engaged with the locking block 302.

[0029] Specifically, by setting the locking component 3, the end cover 2 can be locked and fixed, and the locking method also facilitates the disassembly of the end cover 2, thereby improving the maintenance efficiency of the rotor pump body 1 by the staff.

[0030] A magnetic frame 8 is fixedly connected to the end cover 2, and a magnetic groove 9 that matches the magnetic frame 8 is provided on the rotor pump body 1. The surface of the magnetic frame 8 is in contact with the inner wall of the magnetic groove 9.

[0031] Specifically, by setting up the magnetic frame 8 and the magnetic groove 9 together, the end cap 2 can be limited, thereby improving the installation efficiency of the end cap 2.

[0032] A base 10 is fixedly installed on the rotor pump body 1. The base 10 has four mounting holes, which are symmetrically arranged.

[0033] Specifically, by setting the base 10 and mounting holes to match, it is convenient for workers to fix and install the rotor pump body 1, thereby improving the stability of the rotor pump body 1 in use.

[0034] The rotor pump body 1 is fixedly connected to an inlet pipe and an outlet pipe. Both the inlet pipe and the outlet pipe are welded with flanges, and sealing rings are installed inside the flanges. The sealing rings are circular in shape.

[0035] Specifically, the sealing ring installed inside the flange can improve the sealing performance of the connection between the feed pipe and the discharge pipe and the external pipeline.

[0036] A torsion block 11 is fixedly connected to the end of the lead screw 5 away from the end cover 2. The torsion block 11 is located on one side of the end cover 2 and has anti-slip texture.

[0037] Specifically, by setting the torsion block 11 and the anti-slip texture, it is convenient for the operator to rotate the lead screw 5, thereby improving the adjustment efficiency of the sealing gasket 7.

[0038] Working principle: During use, the operator inserts the magnetic frame 8 on one side of the end cover 2 into the magnetic groove 9 on one side of the rotor pump body 1. The two adhere to each other, allowing the end cover 2 to be pre-positioned. Then, one end of the clamping handle 303 is moved, causing one end of the hook 304 to extend towards the locking block 302. Once the hook 304 is in the designated position, the operator places it on the locking block 302 and presses down on one end of the clamping handle 303. Under the action of the clamping handle 303, the hook 304 is securely engaged with the surface of the locking block 302, thus fixing the end cover 2. After fixing, the operator rotates the torsion block 11. When the torsion block 11 rotates, it drives the lead screw 5 to move laterally in the inner cavity of the threaded sleeve 4. When the lead screw 5 moves laterally, it drives the positioning ring 6 to move laterally. When the positioning ring 6 moves laterally, it drives the sealing gasket 7 to move laterally. After the sealing gasket 7 moves laterally and contacts the blades inside the cavity of the rotor pump body 1, it can improve the sealing between the end cover 2 and the cavity of the rotor pump body 1. In addition, with the setting of the locking part 3, not only is the installation of the end cover 2 fast, but it is also convenient to disassemble the end cover 2, thereby improving the maintenance efficiency of the rotor pump body 1.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
