It is small compared with other motors.Usually there are two types of forms for canned motor pump motor stator winding: ring type winding and formula winding.Ring type around
Group, as its name suggests, for winding made of a kind of single-turn winding coiling of the circle circle with insulation, end does not need additional exhausted
Edge.Formula winding needs 2 windings holding for a kind of half winding of bar shaped that multiturn is solidified togather with the winding of insulation
Portion welds together the winding that can be just linked to be a completion, and end needs outer after the completion of welding plus insulation, to guarantee winding
The continuity of insulation.For formula winding, the common insulation system in end is to be aided with insulation board etc. based on insulating tape wrapping
Auxiliary support.Since canned motor pump motor stator winding overhang space is small, space is small between circle winding and circle winding, operating process
Difficult or even infeasible, the operating time is long, while being difficult to ensure the consistency of winding overhang insulation to increase insulation quality
Uncertainty needs to design a kind of operability, efficiency, the higher stator bar formula winding overhang insulation system of reliability.
Summary of the invention:
It is an object of the present invention to provide a kind of canned motor pump motor stator formula winding overhang insulation systems, and it is whole to shorten winding
Body length improves shielding pump motor winding cavity utilization rate, simplifies insulating wrapping process, improves overhang insulation efficiency, subtract
Lack because of tedious artificial packet insulation process bring risk, improved a reliability for formula winding overhang wrapping insulation.This hair
Bright technical solution are as follows: a kind of canned motor pump motor stator formula winding overhang insulation system, it is characterized in that: outermost turn is to most interior circle

Group (4) trochanter is completely covered, and insulating tape (10) overlaps the second circle winding (4) and has an insulation, insulating boot (6) be mounted on the second circle around
At group (4) trochanter；Insulation board (7) is affixed to first circle winding (5) trochanter inner ring by adhesive tape (11), and channel insulation (8) is mounted on
First circle winding (5) trochanter spine, corner insulation (9) are mounted on two corners of first circle winding (5) trochanter；Insulating boot (6)
It is completely covered at entire winding trochanter, insulating boot (6) overlaps the major insulation wrapped, and insulating boot (6) is fixed to by insulating tape (10)
It fastens block (1).
Working principle:
Primary structure of the present invention is as shown in Figure 1: fastening block wrapping insulating tape and stoppers in the 4th circle winding trochanter inner ring, with exhausted
Edge cover wraps up the 4th circle winding, is fixed to insulating boot with insulating tape and fastens block, insulating boot is completely covered with insulating tape；Use adhesive tape
Insulation board is affixed into third circle winding trochanter inner ring, channel insulation is mounted on third circle winding trochanter spine, corner insulation peace
Mounted in two corners of third circle winding trochanter；Insulation board is completely covered with insulating tape, is stoppered the 4th circle to insulation
Between winding and third circle winding；Insulation board is affixed into the second circle winding trochanter inner ring with adhesive tape, insulating tape by the second circle around
Group trochanter is completely covered, and overlaps the second circle winding and have insulation, and insulating boot is mounted at the second circle winding trochanter；It will with adhesive tape
Insulation board affixes to the first circle winding trochanter inner ring, and channel insulation is mounted on the first circle winding trochanter spine, and corner is insulated
In two corners of the first circle winding trochanter；It is completely covered at entire winding trochanter with insulating boot, overlaps the major insulation wrapped, absolutely
Insulating boot is fixed to and fastens block by marginal zone.
Technical effect:
The present invention insulate applied to canned motor pump motor stator formula winding overhang.Its insulation knot used in turn-to-turn insulation
Structure are as follows: insulating boot and insulation board coat circle winding, insulating tape outside, by insulating boot, insulation board, fasten block bind together it is firm；
Channel insulation is coated on circle winding trochanter spine, corner insulating wrapped circle winding trochanter corner, and insulation board is pasted into adhesive tape
Inside trochanter, by channel insulation, corner insulation, that insulation board is bound together is firm.Whole insulation against ground uses insulation system: wrapping
It ties and coats big insulating boot at the winding trochanter of turn-to-turn insulation, it is firm to be bound with insulating tape.It is tied up with insulating tape conventionally
Ligation structure is compared: the present invention reduces operating space using a large amount of assembled insulation components, and more applicable canned motor pump inside is compact
Design feature；The use for reducing insulating tape simplifies wrapping process, the insulating efficiency of raising；Because simplifying wrapping process, subtract
Manual operation is lacked, has also just reduced artificial wrapping bring uncertainty, improve the reliability of insulation.
