Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vane pumps, in particular to a vane pump with an anti-blocking and sand-discharging mechanism. Background Art
[0002] A vane pump is a pump in which the vanes in the rotor grooves are in contact with the pump housing (stator ring), pressing the sucked liquid from the oil inlet side to the oil discharge side. When the vane pump rotor rotates, the blades are pressed against the inner surface of the stator under the action of centrifugal force and pressure oil. In this way, the working volume formed by the two blades and the inner walls of the rotor and stator first absorbs oil from small to large and then discharges oil from large to small. When the vanes rotate one circle, the oil suction and discharge are completed.
[0003] During use, the existing vane pump will leave impurities in the liquid between the rotor, stator, blades, etc., which not only reduces the service life of the vane pump, but also requires the vane pump to be disassembled to clean the rotor, stator, blades, etc. inside to prevent blockage and inability to rotate. The back and forth disassembly will also cause certain wear on the internal parts, and thus a vane pump with an anti-blocking and sand discharge mechanism is needed. Utility Model Content

[0026] Furthermore, a filter plate 7 is fixedly installed in the middle position of the inner wall of the anti-blocking tube 4, and a rotating fan 9 is rotatably installed at the center position of one end of the filter plate 7 close to the second sealing ring 6. A first arc groove 10 is provided on the blades of the rotating fan 9, and a plurality of filter holes 8 are provided on the filter plate 7, and the plurality of filter holes 8 are arranged in a ring array.
[0027] Furthermore, the fixing device includes two soft plastic connecting plates 11, and the two soft plastic connecting plates 11 are respectively fixedly mounted at the middle position of the top and the bottom of the outer surface of the limiting ring 16, and the two soft plastic connecting plates 11 are arranged in opposite directions.
[0028] Furthermore, a circular groove 12 is provided at the middle position of one end of the two soft plastic connecting plates 11 away from the limiting ring 16, and the inner walls of the two circular grooves 12 are movably clamped with fixing columns 14, and the two fixing columns 14 are respectively fixedly installed on the outer surface of the oil inlet pipe 3 at the middle position of the bottom near the limiting ring 16 and the outer surface of the connecting pipe 15 at the middle position of the top near the limiting ring 16, and a second arc groove 13 is provided at the bottom of one end of the two soft plastic connecting plates 11 away from the limiting ring 16.
[0029] Furthermore, the anti-blocking tube 4 is inserted into the inner wall of the oil inlet pipe 3.

The anti-blocking tube 4 and the oil inlet pipe 3 are sealed by the first sealing ring 5. The movement of the anti-blocking tube 4 drives the limiting ring 16 to move. The movement of the limiting ring 16 drives the circular groove 12 and the second arc groove 13 thereon to move accordingly. When the second arc groove 13 on the anti-limiting ring 16 contacts the fixed column 14, the limiting ring 16 will bend through the curvature of the second arc groove 13, so that the fixed column 14 slides at the bottom.

After completion, when the vane pump body 1 is working, it will absorb liquid into the anti-blocking pipe 4 through the oil inlet pipe 3, and at the same time, the anti-blocking pipe 4 absorbs liquid into the connecting pipe 15, and the connecting pipe 15 sucks the liquid into the inner wall of the anti-blocking pipe 4. When the liquid is in contact with the first arc on the rotating fan 9, When the groove 10 contacts, the flow direction is changed by the setting of the first arc groove 10, so that the liquid continuously impacts the outer surface of each blade fan, thereby providing power for the rotating fan 9. The rotating fan 9 drives the liquid to rotate. At the same time, the liquid enters the oil inlet pipe 3 through the filter holes 8 on the filter plate 7. After use, the user bends the two soft plastic connecting plates 11 away from the fixing columns 14, separates the two fixing columns 14 from the inner wall of the circular groove 12, and separates the first sealing ring 5 and the second sealing ring 6 from the inner wall of the oil inlet pipe 3 and the inner wall of the connecting pipe 15 respectively. The arrangement of the filter plate 7 and the plurality of filter holes 8, and the first arc groove 10 on the rotating fan 9 rotates by liquid power to effectively prevent the plurality of filter holes 8 from being blocked by excessive impurities. The filter plate 7 blocks the impurities in the liquid, thereby effectively preventing the impurities from entering the interior of the vane pump body 1, thereby improving the service life of the equipment. After use, the sand blocking and discharge mechanism can be disassembled for cleaning by the fixing device, effectively preventing the need to disassemble the vane pump body 1 to clean the internal stator, rotor, blades, etc., thereby reducing a certain amount of wear on internal components, and further improving the service life of the equipment.

The movement of the connecting pipe 15 drives the limiting ring 16 thereon to follow the movement, so that the upper limiting ring 16 of the connecting pipe 15 is interactively inserted into the inner wall of the circular groove 12 on another soft plastic connecting plate 11, thereby fixing the sand blocking and discharging mechanism. After completion, when the vane pump body 1 is working, it will absorb liquid into the anti-blocking pipe 4 through the oil inlet pipe 3, and the anti-blocking pipe 4 will absorb liquid into the connecting pipe 15.
