Description

Technical Field

[0001] The utility model relates to the technical field of pump bodies, in particular to a novel sliding vane pump. Background Art

[0002] A vane pump, also known as a blade pump, scraper pump, or scraper pump, is primarily composed of a pump body, inner rotor, stator, pump cover, and vanes. Centrifugal force is primarily used to hold the vanes in close contact with the eccentric stator. As the rotor rotates, the vanes cling to the inner grooves of the pump body and reciprocate within them, forming a periodically changing cavity. Existing vane pumps, due to direct contact between the vanes and the inner wall of the pump body, can wear out the pump body over extended periods of use, causing scratches on the inner wall.

[0003] An improved vane pump is described in the patent with patent publication number CN211288075U. The device now adopts the method of adding a miniature bearing at the end of the vane, so that the sliding friction between the vane and the housing is changed to rolling friction between the housing and the miniature bearing, which greatly reduces the wear of the vane and the housing. In addition, the device also adopts a design of installing a telescopic spring between two symmetrical vanes. It does not need to rely on centrifugal force to throw out, but uses the spring to push the vane to rotate, driving the rotor to rotate, reducing the volume loss of the vane pump.

[0004] However, this technology has its shortcomings when used. In actual use, since the rotor is connected to an external motor, the rotor speed will be extremely high. The rotor drives the vane to reciprocate in the chute, which makes the miniature bearing at the end of the vane rotate at a very high speed. Since the service life of bearing parts is very short, the vane pump with a bearing structure cannot transport media containing impurities, because the impurity particles in the medium can easily get stuck in the above-mentioned bearings, causing bearing damage, which will also shorten the service life of the vane pump; and, since there is still sliding friction between the vane and the chute, the degree of wear of the chute and the inner wall of the pump body will be different, which will cause a gap to always exist between the vane and the housing. This structure will greatly increase the volume loss of the vane pump.

[0005] Based on this, a new type of sliding vane pump is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content

[0029] In one embodiment, Figure 3 As shown, the vane pump 100 includes a pump body 101, in which an eccentric chamber 102 is provided, and a pump body support seat 103 is fixedly connected to the bottom of the pump body 101. An output pipe mounting hole 104 is also provided on the top of the pump body 101, and an input pipe mounting hole 105 is provided on the side of the pump body 101. A fixing block 106 fixedly connected to the pump body 101 is provided on each side of the input pipe mounting hole 105, which is used to fix the quick-detachable input pipe 400 to facilitate the disassembly and replacement of the filter screen 404 in the input pipe 402; a slider mounting hole 107 is provided at one end of the fixing block 106, and a limiting groove 108 is provided on both sides of the fixing block 106 to limit and fix the extension block 703.

[0030] In one embodiment, Figure 4 As shown, the rotor 200 includes a rotating plane 201, in which a plurality of slide grooves 202 are distributed in a circular array, which reserve holes for the sliding of the slide 600; a plurality of equally spaced arc-shaped slide grooves 203 are provided on both sides of the slide groove 202, and the arrangement of the arc-shaped slide grooves 203 makes the slide body 601 fit the slide groove 202 more closely; a rotating shaft 204 is also fixedly connected to the side of the rotating plane 201.

[0031] In one embodiment, Figure 6 As shown, a quick-release input pipe 400 is also provided in the input pipe mounting hole 105. The quick-release input pipe 400 includes a quick-release plate 401. An input pipe 402 is fixedly connected to the quick-release plate 401. A group of symmetrical U-shaped slots 403 are also provided on the side of the quick-release plate 401. The quick-release input pipe 400 is clamped in the input pipe mounting hole 105 through the U-shaped slots 403; a filter screen 404 is also embedded in the input pipe 402.

[0032] In one embodiment, Figure 6 As shown, the fixed block 106 is also equipped with a pressing block 700, and the pressing block 700 includes a cylindrical slider 702, one end of which is fixedly connected to a pressing ring 701, and both sides of the cylindrical slider 702 are provided with an extension block 703 that cooperates with the limiting groove 108, and the tail of the cylindrical slider 702 is also fixedly connected to a guide column 704 to guide and limit the sliding of the cylindrical slider 702; a spring 705 is also sleeved on the outside of the guide column 704.

[0033] In this embodiment, the pressing rings 701 on both sides are pressed simultaneously to make the extension block 703 slide in the limiting groove 108 until the extension block 703 is disengaged from the U-shaped slot 403. At the same time, the guide column 704 is compressed. At this time, the quick-release plate 401 can be easily removed to replace the filter screen 404 in the input pipe 402. Similarly, when the input pipe 402 needs to be connected to the input pipe mounting hole 105, the pressing rings 701 on both sides are pressed again, and the extension block 703 is placed in the U-shaped slot 403 and slid therein to fix the quick-release plate 401.

[0035] In one embodiment, Figure 2 As shown, a pump cover 500 is fixedly connected to the vane pump 100 by bolts. The pump cover 500 includes a pump cover body 501 for closing the vane pump 100; a bearing fixing ring 502 is also provided in the pump cover body 501 to reserve space for the installation of the bearing 800.

[0038] Working principle: First, connect the rotating shaft 204 to the external motor, start the external motor, and the rotating shaft 204 rotates in the eccentric chamber 102. The centrifugal force causes the slide 600 to slide up and down periodically in the slide groove 202, and due to the action of the centrifugal force, the slide 600 will be pressed against the inner wall of the eccentric chamber 102; at the same time, due to the setting of the roller 602 and the side roller 603, rolling friction occurs between the slide 600 and the eccentric chamber 102 and the slide groove 202; in addition, the device is also provided with a pipe with a quick-release structure. By pressing the pressing ring 701, the input pipe 402 and the input pipe mounting hole 105 can be quickly plugged in and fixed, which facilitates the replacement of the filter screen 404.
