Three, connection box for motor body potted line is bad, and time one length has moisture to get into easily;
Four, the poor insulativity of motor greatly reduces useful life of motor.
Summary of the invention:
The present invention is directed to the existing existing variety of issue of motor, can carry out vacuum drying device to motor, can unify to solve the existing existing all problems of motor through the motor that this device processing obtains and provide a kind of.
In order to achieve the above object, the present invention adopts following technical scheme:
A kind of vacuum drying system, this system is made up of vacuum pump, drying system, nitrogen charging device three parts, and said drying system mainly comprises dry terminal box cover, dry sensation temperature control line, the motor drying control cubicle of connecting; The said dry terminal box cover that connects is placed on the connection box for motor body of motor, which is provided with vacuum-pumping tube, and can connect the nitrogen tube in vacuum pump and the nitrogen charging device through this vacuum-pumping tube; Said motor drying control cubicle is connected to the dry terminal box cover that connects through power line, and said power line passes through the lead-out wire that binding post is communicated with motor in drying connects the terminal box cover; Said dry sensation temperature control line connects on the motor casing, and receives and state the motor drying control cubicle.
The motor that the present invention's processing that obtains through technique scheme obtains is compared with the motor that adopts routine techniques to obtain has following advantage:
One, solves the leftover problem that stator coil is pressed into the moisture in the motor cavity in the motor casing assembly, solved the bulging phenomenon of stator plates cover effectively;
Two, motor is in the temperature moisture accelerated evaporation that vacuumizes with 120 ℃ ± 5 ℃ for a long time;
Three, motor drying feeds pressure 0.85kg/cm after accomplishing immediately
2Nitrogen has stoped extraneous moisture to get in the motor cavity, the protection against oxidation after also motor having been carried out heating simultaneously;
Four, connection box for motor body and function glue seals and has guaranteed that moisture no longer gets into, and guarantees also simultaneously that nitrogen is stayed in the motor cavity to protect for a long time;
Five, improve the insulation property and the useful life of motor.
Description of drawings:
Further specify the present invention below in conjunction with accompanying drawing and embodiment.
The sketch map that Fig. 1 implements for the present invention.
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
In order to solve a series of problems that existing motor processing exists, a kind of brand-new system that can carry out vacuumize and nitrogen protection provided by the invention to motor.
Vacuumize that relates among the present invention and nitrogen protecting system, this system is made up of vacuum pump, drying system, nitrogen charging device three parts.Wherein drying system is as shown in Figure 1, mainly comprises dry terminal box cover 3, dry sensation temperature control line 7, the motor drying control cubicle 8 of connecting.
Wherein dry connection terminal box cover 3 is placed on the connection box for motor body 4 of motor, which is provided with vacuum-pumping tube 2, and connects vacuum pumps through this vacuum-pumping tube 2; When operation, this vacuum-pumping tube 2 is used for inflated with nitrogen in the motor cavity is carried out protection against oxidation also as nitrogen blanketing valve simultaneously.
Motor drying control cubicle 8 is the control core of whole Minton dryer, and it is connected to dry the connection on the terminal box cover 3 through power line 1, and this power line 1 also is communicated with the lead-out wire 9 of motor through binding post 5; This motor drying control cubicle 8 connects on the motor casing through dry sensation temperature control line 7 simultaneously, is used for obtaining in real time the temperature of motor cavity inner drying dehumidifying, and can remains on for a long time under the steady temperature state according to the temperature of the temperature information that obtains with desiccant dehumidification.
The practical implementation of the present invention that obtains based on technique scheme is (referring to Fig. 1) as follows:
The first step; Behind the fixed subcoil insulating vacuum paint dipping; Be pressed in the motor casing assembly 6; Stator can is pressed in the stator coil inner chamber, stator can is enclosed within on the stator screen board internal diameter at motor casing assembly 6 two ends again, seals with argon arc welding melting welding at stator can and motor casing assembly 6 two ends stator screen boards then;
Second step connected terminal box cover 3 with drying after welding is accomplished and receives on the connection box for motor body 4 together with the power line on the motor drying control cubicle 81, and power line 1 is communicated with motor lead-out wire 9 through binding post 5;
The 3rd step; The pipe of vavuum pump is connected to the motor cavity to sealing vacuumizes on the dry vacuum-pumping tube 2 that connects on the terminal box cover 3; Simultaneously dry sensation temperature control line 7 is fixed on the motor casing and based on the parameter that the sets intensification of switching on; Make the temperature in the motor cavity under 120 ℃ ± 5 ℃ state, keep 4-8 hour, the moisture in the motor cavity is extracted into vavuum pump through high temperature discharges from vacuum-pumping tube 2, accomplish dry;
In the 4th step, after motor drying is accomplished, immediately nitrogen tube is received on the vacuum-pumping tube 2 motor cavity inside is fed pressure 0.85kg/cm
2Nitrogen carries out protection against oxidation;
The 5th step pull down dry connection terminal box cover 3 at last, and injection glue sealed in connection box for motor body 4, solidified to get into next procedure again after 12 hours.
The motor that obtains according to above-mentioned processing scheme is compared with the motor that obtains that adopts conventional processing technology and is had the following advantages:
One, solves the leftover problem that stator coil is pressed into the moisture in the motor cavity in the motor casing assembly, solved the bulging phenomenon of stator plates cover effectively;
Two, motor is in the temperature moisture accelerated evaporation that vacuumizes with 120 ℃ ± 5 ℃ for a long time;
Three, motor drying feeds pressure 0.85kg/cm after accomplishing immediately
2Nitrogen has stoped extraneous moisture to get in the motor cavity, the protection against oxidation after also motor having been carried out heating simultaneously;
Four, connection box for motor body and function glue seals and has guaranteed that moisture no longer gets into, and guarantees also simultaneously that nitrogen is stayed in the motor cavity to protect for a long time;
Five, improve the insulation property and the useful life of motor.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection range to be defined by appending claims and equivalent thereof.
