[background technique]
Pump is of many uses in life is at present produced, greatly to field irrigation, breed fish for a short time to family's fish jar, all to use pump, and on the market Applicable scope the widest be motor-mount pump nothing more than, it not only can carry various fluids, semifluid, thickness body, and can carry the compounding substances that is mingled with block in the above-mentioned states of matter.
Known motor-mount pump drives waterleaf work by motor by driving mechanism often then, wherein machine shaft all is to be installed in the axle sleeve at motor two ends, provide location and spin friction to transmit by it, waterleaf then is to provide the location by the positioning shaft that establish at the center, cooperate with axle sleeve between the positioning shaft by it again and realize rotation, but the gearing friction power that these two kinds of friction modes all exist area of contact to cause greatly is big and noise is big, and can inevitably cause the drive part of pump inside to produce wearing and tearing in the long-term use, reduced working life, the stability decreases that causes product, even produce potential safety hazard.
[summary of the invention]
The purpose of this utility model is to have overcome above-mentioned defective, and a kind of pump structure that adopts novel rotary shaft mechanism is provided, thus the remarkable reduction of noise when reaching pump operation, and improved its serviceability.
The purpose of this utility model is achieved in that the wear-resisting water pump of a kind of low noise, it comprises shell, is provided with motor and water wheels leaf in the shell, and its improvements are: be provided with partition between motor-end in the shell and the water wheels end of blade, link to each other with shell around the partition, wherein be fixedly connected with positioning seat; The rotating shaft of motor and water wheels leaf is by positioning seat clip in the partition of the rotating shaft supplementary mechanism of an end and the other end therebetween; Described rotating shaft supplementary mechanism comprises that rotating shaft replenishes piece and constitutes with spring, and spring replenishes piece with shell and spring respectively and links to each other, and the additional piece of rotating shaft is set in the respective aperture on the shell, and its end face links to each other with the rotating shaft end face;
The rotating shaft of described motor and water wheels leaf, its two ends are cone-shaped;
The rotating shaft that described cone-shaped rotating shaft two ends link to each other replenishes piece and the corresponding cone-shaped depression that is provided with in positioning seat surface;
It is coaxial that the positioning seat upper and lower surface is respectively applied for the depression that connects motor and water wheels leaf;
The rotating shaft of described rotating shaft supplementary mechanism replenishes piece and is set in and closely cooperates and slidably in the corresponding blind hole of shell; Described spring is arranged at rotating shaft and replenishes in piece and the blind hole formation cavity;
Described water wheels leaf rotating shaft side is provided with the depression that is used for clamping water wheels leaf.
Than common water pump, the beneficial effects of the utility model are to adopt new rotating shaft clamping device to replace original rotating shaft, the drive mechanism that axle sleeve cooperates, by the positioning seat of rotating shaft clip in an end replenished between the seat with the rotating shaft that the other end links to each other with spring, supported and subtract and the change of certain axial elasticity is provided, greatly reduce the area of contact between rotating shaft and the support end, thereby reduced in the rotating shaft rotation process the frictional force that can be subjected to, realized reducing the purpose of noise, and, each rotating shaft replenishes seat because all disposing rotating shaft, when in a single day rotating shaft is worn, rotating shaft replenishes seat and promptly automatically the gap that produces is replenished under the extruding of spring, not only can guarantee the stability that rotating shaft is rotated, also make package unit more durable in use.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is the utility model water pump cross-sectional view.
The rotary shaft mechanism structural representation of Fig. 2 for being adopted in the utility model water pump.
[embodiment]
Referring to Fig. 1, the utility model relates to the wear-resisting water pump of a kind of low noise, it comprises shell, shell is by water wheels end of blade lid 1, electric motor end cap 3 constitutes, be provided with partition 2 between motor end cap 3 and the water wheels end of blade lid 1, be provided with positioning seat 10 in the partition 2, link to each other with shell around it, be respectively arranged with water wheels leaf 6 and motor 5 in the cavity of being separated by partition 2 up and down, carry out magnetic drives by the annular magnetic steel 602 and 502 that one links to each other as for the water wheels leaf 6 in two isolated chambers respectively with motor 5 respectively, the principle of utilizing two groups of like poles in the magnetite to repel mutually promotes the rotation of waterleaf, wearing and tearing when further having reduced pump operation and noise, and owing to adopted the mode of complete isolated water wheel blade 6 and motor 5, make the contingent unexpected electric leakage of motor-end can not be transmitted to the waterleaf end, guaranteed the safety in the working procedure.
Shown in Fig. 1, water wheels leaf 6 is fixedly linked with it by the depression in the rotating shaft 601, the rotor of motor 5 and rotating shaft 501 are for one links to each other, and motor 5 becomes cone-shaped with the rotating shaft termination of water wheels leaf 6, respectively by the rotating shaft supplementary mechanism of end separately and positioning seat 10 clips in the partition 2 therebetween.
