Abstract
The present invention provides a method for manufacturing a sealed miniature submersible pump, which comprises the following steps: after a stator coil is fixed and a rubber core is assembled, a stator assembly is formed; then, the stator assembly is put into an injection mould, and thermoplastic or thermosetting materials are injected into the injection mould to produce a full-sealed pump body of a miniature submersible pump; finally, an impeller, a rotor, a water inlet and a water outlet are assembled into the pump body so as to form a full-sealed miniature submersible pump.
Description
The present invention relates to a kind of manufacture method of totally-enclosed micro pump.
Existing miniature immersible pump manufacture method comprises the making stator assembly, then stator assembly is loaded in the housing, and housing is separated stator assembly and rotor assembly, and stator assembly installs back derivation lead-in wire and pours into resin-sealed stator in housing.Pack into then rotor, impeller or blade, intake-outlet.Two operations of poured with epoxy resin and shell injection moulding, operation is many, uses the production area big, and small product size is big, and materials are many, the manufacture cost height, and productivity is low, and poured with epoxy resin speed is slow.
The objective of the invention is the direct injection moulding of stator assembly, save injection casing and operation.
Technical step of the present invention is:
On A, the stator glue core outlet ejector is arranged, on the glue core around on enameled cable, enameled cable two ends are connected on the lighting outlet by the outlet ejector.
B, glue core are contained in and form stator assembly on the stator iron core.
C, stator assembly is put into mould, stator assembly is surrounded by mould and forms injection moulding agent flow channel and space.
D, behind matched moulds, mould pushes each positioning block, produces positioning action.
E, in mould, inject thermoplasticity or thermosetting plastics, injection moulding agent complete closed stator iron core and line bag, formation pump body.
F, pack in stator cavity rotor and blade assembly are pressed into the water pump end cap on the pump housing, form water pump complement.
Locate in mould for stator assembly, the method for one is that many positioning blocks and mould location are arranged on stator glue core, and the center of stator is by setting sleeve and mould location.Also can adopt the mode of thimble secured core to locate stator assembly.
End cap is provided with guide plate and labyrinth ring, and water outlet is arranged, and the end cap inner chamber has an annular protrusion and stator relative position groove fit, allows end cap and stator to do 360 and rotates, and changes the water outlet angle of water.Impeller adopts the channel-type structure to reach the generation that reduces mixed flow.Impeller is provided with labyrinth ring and matches with labyrinth ring on the end cap and produce the labyrinth effect.Rotor and water pump spindle adopt press fit, and impeller and water pump spindle produce movingly, help improving the concentricity of rotor and impeller.The injection moulding of rotor is finished with the method for isobaric injection moulding, in the rotor injection moulding to magnet ring inside and outside isobaric injection moulding, that removes the magnet ring rotor outside after finishing waits compression technology injection moulding limit, avoids the magnetic material breakage.
In the water pump bottom a plurality of suckers, positioning sucker disk are housed.Water outlet is equipped with water yield by-pass cock.
Water pump adopts the synchronous machine principle, and directed characteristics of rotating of motor and the end cap impeller that cooperates all adopt omnidirectional, has that noise is low, efficient is high, and the advantage that volume is little is sealed close water pump entirely, is suitable for diving work.The needs that are used for potted landscape, fish jar, cycling use of water.

The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
As shown in Figure 8: glue core I, II are contained in stator iron core (24) and go up formation stator assembly (1).The glue core is to be used for coiling coil of stator of motor (25), and a plurality of outstanding positioning blocks (22) are arranged on the glue core, and the power supply lead-in wire (14) of stator is connected with the enameled cable of staor winding by the lead-in wire groove (26) on the glue core; The enameled cable of staor winding contracts out wire casing (27) by line and is drawn out in the lead-in wire groove (26), the tail mould (13) of stator supply lines is fixed on the tail mould fixed handle (28) of glue core, positioning adapter (23) is packed in the stator cavity, setting sleeve cooperates with the mandrel of mould, make the center obtain accurate in locating, mould produces impacting force to setting sleeve and positioning block behind the matched moulds simultaneously, makes stator iron core (24) and coil (25) that accurate in locating be arranged in mould;
When the magnetic core of p-m rotor (5) has the rotor (2) of epitrochanterian clutch tooth (16) in injection moulding, with general injection moulding process, because magnetic core is a brittle material, when injection moulding, injection pressure is from magnetic core endoporus radius vector pressuring direction, magnetic core is cracked, for make magnetic core in injection moulding in the pressure that equated of external diameter, the isobaric injection moulding of this method with external diameter while injected plastic in the magnetic core, guarantees to be subjected to identical power inside and outside the magnetic core, make the magnetic core stress balance, the garden is as the steady technology plastic sheet of pressure except that magnetic core after injection moulding is finished, and (6) are rotor bushing, and (21) are rotor shaft hatch.
Water pump vane is provided with impeller labyrinth ring (17) and cooperates with the labyrinth ring of end cap (7), and labyrinth clearance (11) makes the zone of high pressure of water pump inner chamber and the low pressure of water intake play buffer action, keeps to consume the pressure that produces the chamber, improves the lift and the flow of water pump.Impeller ring (18) and blade (20) are set on impeller form passage, make impeller also form lift and flow that zone of high pressure and low pressure area help improving water pump.General design is that impeller is contained in magnetic core and puts, and quality of fit is poor, and the impeller axis hole (19) of this scheme and water pump spindle (4) directly effectively improve the precision of rotor-support-foundation system movingly, and the noise that reduces water pump is had very big effect.Epitrochanterian clutch tooth (16) cooperates with clutch tooth (15) on the impeller.
The cooperation of impeller of rotor system: rotor shaft (4) is to be supported on two bearing supports of pump body (12) and water intake, with the axial clearance (3) of bearing support be that size by water pump spindle, housing and water intake guarantees, and the end cap bearing is adjusted by the position of back-up ring (9) with the gap (10) of axle.
The general assembly of water pump: after water pump cover is put into rotor-support-foundation system, water intake is pressed into the annular groove location of water pump shell with the interior pleurapophysis ring and the water pump shell of water intake.This moment, 360 rotation can be done in the water outlet position of water pump, and originally to close the requirement of different water outlets position, water outlet is furnished with multiple different joint, can adapt to the joint of different-diameter water pipe, and water outlet is furnished with the water outlet by-pass cock, can regulating water-quantity.
