The other side of fixed bracket 13 is equipped with connecting terminal 15, and the inside of connecting terminal 15 is electrically connected with one end of carbon brush 3, sealing piston
II 9, sealing piston I 8 and the outer surface of the fixed frame 4 in the inner cavity for being located at stop sleeve 5 are equipped with rubber sheet gasket, to increase
Frictional force between sealing piston II 9, sealing piston I 8, fixed frame 4 and stop sleeve 5, prevents the device in the process used
In, space closed between closed space or sealing piston II 9 and fixes sleeve 6 hair between sealing piston I 8 and fixed frame 4
The problem of raw gas leakage, effectively raise the stability and reliability of the device in use.
In the technical program, the inner cavity of stop sleeve 5 is set as boss structure, and the inner wall of 5 larger interior diameter of stop sleeve is solid
Dingan County is equipped with fixes sleeve 6, while the smaller internal diameter of stop sleeve 5 is identical as the inner diameter size of fixes sleeve 6, for support sleeve
The setting of boss structure, increases leakproofness when stop sleeve 5 is fixedly connected with fixes sleeve 6, protects simultaneously in 5 inner cavities of cylinder
The movable fluency when moving up and down of sealing piston I 8 is demonstrate,proved, it is ensured that sealing piston I 8 will not block during movable
The phenomenon that plug.
In the technical program, the two sides of fixes sleeve 6 offer L-type through-hole, and sealing piston I 8 is in corresponding circumference
L-type through-hole is equally offered on position, but between fixes sleeve 6 and sealing piston I 8 corresponding L-type through-hole in upper and lower position
On be staggered, the setting for L-type through-hole and its position in fixes sleeve 6 and sealing piston I 8 can use sealing piston I 8
Movement connect or disconnect L-type through-hole, thus using pressing spring 10 come to inner cavity between sealing piston I 8 and fixed frame 4
Pressure is adjusted, and prevents from causing its pressure between collector ring 2 to become smaller due to the abrasion of carbon brush 3 shortens, eventually leads to collection

On the outer surface of ring 2, setting for two groups of scraper plates 14 of symmetry arrangement, no matter the positive and negative rotation of motor, can collector ring 2
Carbon distribution on surface is cleared up, and is prevented when the carbon distribution on 2 surface of collector ring is excessive to cause collector ring 2 and carbon brush 3 to contact
Resistance is excessive and the phenomenon that generate electric spark, it is effective to improve collector ring 2 and stability of the carbon brush 3 in sliding friction.
In the technical program, the bottom on 4 top of fixed frame is less than carbon brush 3 to the distance between 5 intracavity bottom of stop sleeve
Effectively use length, for 4 top of fixed frame bottom to the setting of distance between 5 intracavity bottom of stop sleeve, can be effective
The use length for controlling carbon brush 3 prevents from causing to send out between the metal material on its top and collector ring 2 due to carbon brush 3 is too short because rubbing
The case where raw frictionally damage.
Rolling friction will occur for working principle, in carbon brush when motor start-up work between collector ring 2 and carbon brush 3
3 during use due to abrasion and when shortening, and will drive sealing piston I 8 to moving down under the elastic force effect of holddown spring 7
It is dynamic, the inner cavity between compression seal piston I 8 and fixed frame 4, and drive fixed frame 4 and carbon brush 3 to move down and keep beginning carbon brush
The sealing piston I 8 for remaining the state of contact between 3 and collector ring 2, while moving down can be connected to fixes sleeve 6 it
Between L-type through-hole, by the air between fixes sleeve 6 and sealing piston II 9 in inner cavity under the elastic force effect of pressing spring 10
It is compressed in the inner cavity between sealing piston I 8 and fixed frame 4, while driving sealing piston I 8 to move up and compressing compression bullet
Spring 7, and the sealing piston I 8 moved up can cut off the connection with the L-type through-hole in fixes sleeve 6, to guarantee to compress
The deformation quantity of spring 7 will not change because of the abrasion of carbon brush 3, and then ensure that the pressure between collector ring 2 and carbon brush 3 is protected
It holds constant；
When carbon brush 3 is replaced because of excessive wear, rotation adjusting screw rod 12 first drives fixed plate 11 to moving up
Pressing spring 10 is loosened while dynamic, is then turned off being electrically connected between one end of carbon brush 3 and connecting terminal 15, takes out damage
Carbon brush 3, new carbon brush 3 is put into the inner cavity of fixed frame 4 later, and is electrically connected with the inside of connecting terminal 15, then
Upward fixed frame 4 drives sealing piston I 8 to move up compression holddown spring 7, so that the L-type through-hole on stop sleeve 5
Inner cavity between sealing piston I 8 and fixed frame 4 is connected to, and the air between sealing piston I 8 and fixed frame 4 in inner cavity is arranged
Enter into the inner cavity between fixes sleeve 6 and sealing piston II 9 and compress pressing spring 10, is moved to suitable position in carbon brush 3
When setting, fixed frame 4 is unclamped, while driving sealing piston I 8 to move down closing fixing sleeve under the effect of the elastic force of holddown spring 7
Cylinder 6 on L-type through-hole, rotate backward again later adjusting screw rod 12 drive fixed plate 11 move down give pressing spring 10 press
Accumulation of energy, to complete the replacement to carbon brush 3.
