Abstract
The utility model relates to a plugging-free hydraulic transmission pump which mainly comprises a pump body, a pump cover, an impeller, an elastic check ring for hole, an oil seal, a shaft, a rolling bearing, an outlet pipe, an elastic gasket, a supporting frame and a connecting flange, wherein a hydraulic pump is connected and mounted at the connecting flange; a rotating shaft of the hydraulic pump is integrally connected with a shaft sleeve in the pump body through the connecting flange; the impeller is connected with the bottom end of the shaft in the pump body; the supporting frame is connected with the outer side of a bottom port of the pump body; the supporting frame has a cylindrical frame structure; the top and bottom of the supporting frame have isometric circular structures; 3-5 vertical connecting rods are welded between the top and the bottom, thereby forming the cylindrical frame structure; and the top is covered on the bottom port of the pump body and is fixedly connected with the bottom of the pump body through a connecting sheet and a hexagonal bolt. The plugging-free hydraulic transmission pump has the advantages of convenience, practicability, high efficiency, wide application, small volume, and the like.
Description
Technical field
The utility model relates to a kind of pump, especially a kind of pump that is used for blowdown, does not have obstruction.
Background technique
The pump housings such as existing sewage pump, slurry pump all adopt motor and pump housing tight connecting device, and it is bigger that its operating range is influenced by motor volume, weight; There are many shortcomings in this type of pump housing, and for example: 1, motor closely is connected with the pump housing, during work; Pump head and motor integral body slip under the liquid level, and the lead that has only motor stretches out and is connected with electric controller from liquid level, and operating range is limited by conductor length; If conductor length is shorter; Then work distance is just little, if increase conductor length, has potential safety hazards such as electric leakage, kinking also.2, the drive motor working portion is in the environment such as mud, cesspool, need be to the in addition tight waterproofing protection of circuit, pump head, thereby make this type of pump body structure comparatively complicated, increase cost and quality, not only made troubles but also increased manufacture cost to work.3, the bore of pump housing inlet is too small, in blowdown work, is easy to run into blockage problem, makes troubles to work, more can cause serious accidents such as pump housing shutdown, circuit burnout when serious.
Summary of the invention
The purpose of the utility model provides that a kind of operation is nimble, convenient and practical, technology does not reasonably have the obstruction hydraulically driven pump.
The utility model mainly comprises the pump housing, pump cover, impeller, circlip for hole, oil sealing, axle, rolling bearing, outer pipe, elastic washer, supporting frame and adpting flange, at adpting flange place connection oil hydraulic pump; The axle sleeve that the rotating shaft of oil hydraulic pump sees through in the adpting flange and the pump housing connects composition integral body, and the axle bottom in the pump housing is connected with impeller; The mouth outside connects supporting frame at the bottom of the pump housing, and support frame as described above is cylindric frame structure.Supporting frame top and bottom such as are at big circle structure, between two kinds, are welded to form cylindric frame structure through 3～5 vertical connecting rods, and the top covers mouth at the bottom of the pump housing, and through being fixed in pump housing bottom with hex head bolt in flakes.
During work, use the motor drives hydraulic pump works, oil hydraulic pump is exported to oil inlet pipe to the hydraulic oil in the fuel tank; Oil inlet pipe is sent the pump motor of oil hydraulic pump to, and the pump motor drives the rotating shaft rotation, and rotating shaft drives coupled axle and rotates; The axle impeller is rotated, thereby realizes the driving purposes to pump, and pump is started working; Suck the supporting frame of dirt mouth below at the bottom of the pump housing; Finally discharge through the impeller drive after getting into the pump housing,, therefore can suck the bigger dirt of volume (as: sanitary napkins, weeds, plastic bag etc.) because the end mouth of the pump housing is bigger from outer pipe.In addition, because oil hydraulic pump and drive motor are through being connected into and out of oil pipe, so the length of oil pipe has determined the work distance of pump head; At this moment; Pump head can immerse separately and carry out work under the sewage level, and drive motor can safety fix on the ground, need not under the immersed in liquid level; So can improve the Security and the working life of drive motor, and can avoid potential safety hazards such as electric leakage.
Compared with present technology, the beneficial effect of the utility model is:
1, rational in infrastructure, convenient and practical, advantage such as efficient is high, be widely used, volume is little.
2, operating range is big, can enlarge or dwindles work distance and scope through the turnover oil pipe, is particularly suitable for remote-controlled operation and uses.
3, safe, operation is nimble, has only during work under the pump head part immersed in liquid level, its drive motor part can be fixedly mounted on safe ground; Drive motor need not to move, and can improve safety in utilization, avoids accidents such as electric leakage; And can avoid the danger such as wearing and tearing, immersion of drive motor; Prolong the working life of drive motor, also reduce the volume and the quality of pump head, increase operating flexibility.
Description of drawingsFig. 1 is the planing surface structural drawing of the utility model.
Drawing reference numeral: the 1-pump housing, 2-pump cover, 3-impeller, 4-circlip for hole, 5-oil sealing, 6-axle, 7-rolling bearing, 8-outer pipe, 9-hex head bolt, 10-supporting frame, 11-adpting flange, 12-oil hydraulic pump, 13-rotating shaft.
EmbodimentIn the planing surface structural drawing of the utility model shown in Figure 1; Mainly comprise the pump housing, pump cover, impeller, circlip for hole, oil sealing, axle, rolling bearing, outer pipe, elastic washer, supporting frame and adpting flange, at adpting flange place connection oil hydraulic pump; The axle sleeve that the rotating shaft of oil hydraulic pump sees through in the adpting flange and the pump housing connects composition integral body, and the axle bottom in the pump housing is connected with impeller; The mouth outside connects supporting frame at the bottom of the pump housing, and support frame as described above is cylindric frame structure.Supporting frame top and bottom such as are at big circle structure, between two kinds, are welded to form cylindric frame structure through 3～5 vertical connecting rods, and the top covers mouth at the bottom of the pump housing, and through being fixed in pump housing bottom with hex head bolt in flakes.
