Abstract
The utility model discloses a reshaping mould for a stator shielding sleeve of a shielding pump. The reshaping mould is composed of a mandrel, a rubber sleeve, a limiting nut and a locking nut, wherein a central hole and a radial hole are processed at the upper end of the mandrel, and the central hole is communicated with the radial hole. Two ends of the rubber sleeve are in U-shaped, and the whole rubber sleeve is sleeved outside the mandrel, fixed by the limiting nut and locked by the locking nut. When liquid is filled in the rubber sleeve through the central hole and the radial hole of the mandrel, sealing is formed between the U-shaped inner sides at two ends of the rubber sleeve and the mandrel. The sealing surface of the mandrel of the reshaping mould is performed with chroming or satellite spraying, so that the smoothness and abrasion resistance of the sealing performance are improved. In reshaping, users only need to insert the mould into an inner cavity of the stator shielding sleeve, fill oil or water in from the central hole at the upper end of the mandrel and perform pressurizing, so that the outer wall of the rubber sleeve can be firmly adhered to the shielding sleeve so as to reshape the stator shielding sleeve. The reshaping mould is simple in structure, convenient to operate and high in production efficiency.
Description
Technical field
The shaping mold of the described canned motor pump stator can of the utility model relates to a kind of shaping mold, particularly relates to a kind of shaping mold of canned motor pump stator can.
Background technology
The stator of present employed canned motor pump all has housing, stator coil and pumped (conveying) medium is kept apart, if housing is too thick; Will increase motor gas-gap, reduce electric efficiency, if too thin; Tubing up to specification is difficult to buy, and at present, generally adopts the thick sheet material of 0.4mm-0.6mm to roll welding; In order to guarantee its circularity in bore of stator, must carry out shaping and handle.Existing shaping methods is to load onto flange at the stator two ends with bolt, and wherein an end flanges has interface, through this interface oiling or water and pressurization in the stator can chamber, carries out shaping.Shaping is taken off two end flanges after accomplishing, and oil in the bore of stator or water are bled off.This method troublesome poeration, inefficiency, and difficult to the recovery of oil or water, pollute working environment, increased production cost.To existing problem in the above-mentioned prior art, the shaping mold of a kind of novel canned motor pump stator can of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art; The purpose of the utility model is the shaping mold of a kind of novel canned motor pump stator can of research and design, thus solve the existing troublesome poeration of present employed shaping methods, inefficiency and to the recovery difficulty of oil or water, pollute working environment, increased problem such as production cost.
The shaping mold of the described canned motor pump stator can of the utility model is made up of mandrel, gum cover, stop nut and locking nut.The upper end of described mandrel is processed with centre bore and radial hole, and two holes communicate; Described gum cover two ends become the U font, and whole gum cover is enclosed within the mandrel outside, by the stop nut fixed position, and lock with locking nut; When the centre bore through mandrel, radial hole during the fluid injection pressurization, form sealing between the inboard of gum cover two ends U font and the mandrel in gum cover.The sealing surface of the described mandrel of the utility model carries out surface treatments such as chromium plating or spraying Si Taili, increases the fineness and the wearability of sealing surface.
The purpose of the shaping mold of the described canned motor pump stator can of the utility model provides a kind of shaping mold of simple in structure, easy to operate, stator can that production efficiency is high, overcomes the deficiency of prior art.
The course of work and beneficial effect that the nothing of the utility model is stopped up canned motor pump are: the inner chamber that only needs this mold is inserted the stator can after having installed; The primer fluid press pump, liquid during the fluid injection pressurization, forms sealing through the centre bore of mandrel, radial hole between the inboard of gum cover two ends U font and the mandrel in gum cover; Just can carry out stator can is carried out shaping; Shaping does not need oil in the gum cover or water are bled off after accomplishing, and only needs pressure release; Just can mold be extracted out from the stator can inner chamber, carry out operation next time.This mold is not only simple in structure, easy to operate, production efficiency is high, free from environmental pollution, can also reduce production costs.
Description of drawings
The utility model has a width of cloth accompanying drawing,
Fig. 1 is the shaping positioner structure sketch map of canned motor pump stator can.
Among the figure: 1, mandrel, 2, gum cover, 3, stop nut, 4, locking nut.
The specific embodiment
For example shown in the accompanying drawing 1, the shaping mold of described canned motor pump stator can is made up of mandrel 1, gum cover 2, stop nut 3 and 4 of locking nuts in the practical implementation of the utility model.Described gum cover 2 two ends become the U font, and gum cover 2 is enclosed within mandrel 1 outside, by stop nut 3 fixed positions, and locking nut 4 lockings.The upper end of described mandrel 1 is processed with centre bore and radial hole; Two holes communicate; When fluid injection is pressurizeed in the centre bore that passes through mandrel 1, the past gum cover 2 of radial hole; Form sealing between the inboard of gum cover 2 two ends U fonts and the mandrel 1, the sealing surface of mandrel 1 carries out surface treatments such as chromium plating or spraying Si Taili, increases the fineness and the wearability of sealing surface.
During actual the use; Only need this mold is inserted in the corresponding stator can, inject oil or water and pressurization inward, form between gum cover 2 two ends inwalls and the mandrel 1 and seal by the centre bore of mandrel 1; Gum cover 2 outer walls will be close to stator can, and stator can is carried out shaping.After shaping is accomplished, only need pressure release, just can mold be extracted out from the stator can inner chamber, carry out operation next time.
Claims (2)
