But Fig. 1 is the submersible pump of embodiment's 1 described vertical strain splits structural representation.
Fig. 2 is the structural representation that embodiment's 1 described height is regulated fixed mechanism.
But Fig. 3 is the submersible pump base of embodiment's 1 described vertical strain closes up the structural representation under the state.
But Fig. 4 is the submersible pump base of embodiment's 1 described vertical strain is fully withdrawn the structural representation under the state.
Embodiment
Below in conjunction with specific embodiments and the drawings the technical solution of the utility model is further elaborated, but mode of execution of the present utility model is not limited thereto.
Embodiment 1
Shown in Fig. 1-4, but the submersible pump of the described a kind of vertical strain of present embodiment, comprise the pump housing 40, its middle pump body 40 bottoms are provided with internal base 20, described internal base has outer cylinder surface, described outer cylinder surface offers the groove that extends to the bottom from described outer cylinder surface top, be provided with in the described groove and highly regulate fixed mechanism, described height is regulated fixed structure and is comprised plastics shell fragment 30, described plastics shell fragment 30 surperficial four jiaos have tapped hole 34, and utilize set screw to be installed in the described groove; Described plastics shell fragment 30 is distributed with a plurality of draw-in grooves 32 along short transverse, and the bottom of described plastics shell fragment also is provided with grab retaining thread hole 36 in addition; Described fixed base comprises base plate 12 and the hollow cylinder bearing 14 that is arranged on the base plate, and the inwall of described hollow cylinder rest base 14 is provided with hole clipping 18, and described hollow cylinder bearing top is provided with base grab 16; The hollow cylinder bearing cover of described fixed base is set on the internal base, utilizes fixed base grab set screw 19 to pass grab retaining thread hole 36 fastening links the on the plastics shell fragment on hole clipping 18 and the described internal base; The resiliently deformable that relies on described plastics shell fragment 30 with make the hollow cylinder bearing 14 of fixed base 10 be fixed in the corresponding draw-in groove 32 of described plastics shell fragment cooperating of base grab 16.The groove that described outer cylinder surface is offered is preferably 2, can certainly be a plurality of, and is provided with 2 or a plurality of height adjusting fixed mechanism and 2 or a plurality of base grab accordingly, thereby can realize regulating stably.
In the submersible pump described in the utility model, the outer cylinder surface of internal base matches with the internal surface of the hollow cylinder bearing of fixed base, and needs frequent drawing, thereby smooth surface need be provided, thereby is conducive to vertical strain easily.But because submersible pump is immersed in the environment of the medium easy corrosion of water for a long time, and described submersible pump internal base is closed fixed base and is made by metallic material such as cast irons usually, cause corrosion easily, thereby cause between the internal surface of outer cylinder surface and hollow cylinder bearing corrosion stuck easily.Therefore, as preferably, outer cylinder surface in described internal base is coated with the finishing coat that the wear-and corrosion-resistant coating composition forms, described wear-and corrosion-resistant coating composition comprises: the epoxy resin of 22.5-30.8wt%, the zinc powder of 15.0-22.5wt%, the zine oxide of 5.0-8.7wt%, the ethanol of 10-15wt%, the methyl ethyl carbonate of 3-5wt% and the water of surplus; The thickness of described coating is 2-10mm.Further preferably, applied phosphating coating earlier before the coated side coating, the phosphatization liquid that described phosphating coating uses comprises: 85% phosphoric acid of 2.2-3.6wt%, the zinc dihydrogen phosphate of 7.5-12.5wt%, the ethylene glycol of 12-25wt% and the water of surplus.Above-mentioned phosphatization liquid is sprayed directly into the metal conditioner layer of outer cylinder surface (through cleaning and the alligatoring pretreatment) the formation 10-20 μ m of internal base.As preferably, the internal surface of described hollow cylinder bearing is coated with the finishing coat that anti-corrosion self-lubricating coating composition forms, described anti-corrosion self-lubricating coating composition comprises: the epoxy resin of 22.5-30.8wt%, the Barium Fluoride of 10.0-17.5wt%, the nickel borides of 8.7-12.5wt%, the ethanol of 12-15wt%, the methyl ethyl carbonate of 5-8wt% and the water of surplus; The thickness of described coating is 2-10mm.By applying above-mentioned finishing coat, can guarantee the described internal base of whole life cycle drawing easily at submersible pump, and corrosion and stuck phenomenon can not take place.
