The bidirectional hydraulic putty spray painting device operation principle of the present invention is as follows:
Hopper 5 accommodates the medium that will be sprayed-on, can be respectively to first medium entrance 261 and second by medium delivery pump 4
Medium inlet 281 supplying media.
When the stroke of the main piston 120 of bidirectional hydraulic transformator 100 starts, oil pump 2 goes out to the hydraulic oil of Master cylinder body 110 left end
Entrance 111 injects hydraulic oil, and main piston 120 moves the most to the right from left side initial position (top), meanwhile, in main work
Under the drive of plug 120, the first subpost plug 140 and the second subpost plug 160 move the most to the right.At this moment, coordinated type electromagnetism post
First plunger rod 250 of plug high pressure check valve 200 is positioned at the high order end of stroke in the first valve barrel body 260 so that first medium enters
Mouth 261 and first medium connector 262 are respectively positioned on the right side of the first plunger rod 250, first medium entrance 261 and first medium
Connector 262 connects (such as Fig. 6 a), and the second plunger rod 270 is positioned at the high order end of stroke in the second valve barrel body 280 so that
Second medium entrance 281 and second medium connector 282 lay respectively at the both sides of the second plunger rod 270, second medium entrance 281
With the passage between second medium connector 282 disconnects (such as Fig. 6 a), i.e. now medium can pass through first medium entrance 261
With the first medium gateway 131 that first medium connector 262 enters into bidirectional hydraulic transformator 100, medium can not be by the
Second medium connector 282 enters second medium gateway 151, but the medium in the second subsidiary cylinder 150 comes in and goes out from second medium
Mouth 151 is by second medium outlet 283 discharge (such as Fig. 6 a, 6b, 7a)；Until main piston 120 moves to Master cylinder body 110
Terminal position (i.e. the low order end of stroke in Master cylinder body 110), such as Fig. 7 a～7b, correspondingly, the first subpost plug 140 moves to
The low order end of the first Master cylinder body 130, the contact switch 112 triggering Master cylinder body 110 left end closes, electromagnetic steering, position-sensing switch
Receive the closure signal of contact switch 112, send turn signal to hydraulic steering valve 8, give coordinated type electromagnetic plunger high simultaneously
The first electric magnet 221 on pressure check valve 200 is energized.
Then, the main piston 120 of bidirectional hydraulic transformator 100 will from end of travel to top setting in motion (such as Fig. 9 a～b),
Due to the steering-effecting of hydraulic steering valve 8, hydraulic oil is injected by the hydraulic oil gateway 111 of Master cylinder body 110 right-hand member, main work
Plug 120 moves to the left from right end position, meanwhile, under the drive of main piston 120, and the first subpost plug 140 and second
Subpost plug 160 moves the most to the left, and at this moment the contact switch 112 of Master cylinder body 110 left end disconnects.And the first electric magnet 221
After energising, owing to it is orientation electric magnet, the first electric magnet 221 drives the first plunger rod 250 and the second plunger rod 270 to the right
Lateral movement, the first plunger rod 250 through first medium connector 262 to first medium entrance 261 1 lateral movement so that first be situated between
Matter entrance 261 and first medium connector 262 are positioned at the both sides of the first plunger rod 250, and now second medium entrance 281 He
Second medium connector 282 is still located at the both sides (such as Fig. 8 a) of the second plunger rod 270, but the bullet on the second buffer portion 240
Spring 243 is squeezed, and guide rod 242 enters into the leftmost side of buffering guide 241 stroke, plays cushioning effect.I.e., now it is situated between
Matter can not enter into first Jie of bidirectional hydraulic transformator 100 from first medium entrance 261 by first medium connector 262
Matter gateway 131, can not enter into second medium gateway from second medium entrance 281 by second medium connector 282
151, and the medium in the first subsidiary cylinder 130 can be discharged (such as figure from first medium gateway 131 by first medium outlet 263
8a, 8b, 9a), above-mentioned for main piston 120 from end of travel to the first stage of top setting in motion.
It follows that the spring 243 on the second buffer portion 240 is replied, and guide rod 242 moves to buffer guide 241 to the right
The rightmost side of stroke, the second plunger rod 270 also moves into the rightmost side of the second valve barrel body 280 so that on the second valve barrel body 280
Normally closed type contact switch 284 disconnect, first medium entrance 261 and first medium connector 262 are still located on the first plunger rod
The both sides of 250, second medium entrance 281 and second medium connector 282 are respectively positioned on the left side (Figure 10 a) of the second plunger rod 270,
I.e., now medium can not enter into bidirectional hydraulic transformator 100 from first medium entrance 261 by first medium connector 262
First medium gateway 131, but second Jie can be entered into from second medium entrance 281 by second medium connector 282
Matter gateway 151, meanwhile, the medium in the first subsidiary cylinder 130 can be exported by first medium from first medium gateway 131
263 discharge (such as Figure 10 a, 10b, 11a), the first electric magnet 221 power-off.Correspondingly, the second subpost plug 160 moves to
The high order end of two Master cylinder bodies 150, the contact switch 112 triggering Master cylinder body 110 right-hand member closes, and electromagnetic steering, position-sensing switch connect
Receive the closure signal of contact switch 112, then send turn signal to hydraulic steering valve 8, give coordinated type electromagnetic plunger simultaneously
The second electric magnet 222 on high pressure check valve 200 is energized.Above-mentioned for main piston 120 from end of travel to top setting in motion
Second stage.Then, main piston 120 continues to move, until main piston 120 moves to master cylinder to stroke top on this basis
The position, top (i.e. the high order end of stroke in Master cylinder body) of body 110.
Then, main piston 120 moves from stroke top to end of travel, also passes through two stages, with above-mentioned during its setting in motion
The process that main piston 120 moves to stroke top from end of travel is corresponding.So constantly repeat said process so that medium can
Continuously to discharge to spray-painting gun from medium outlet, spraying produces the most coherent.Main piston 120 due to the present embodiment
It is 2.6 times with the cross-sectional area ratio of the first subpost plug 140 or the second subpost plug 160, so the first subpost plug 140 or the second
The pressure that gear oil pump is discharged is brought up to 2.6 times by the one-way hydraulic cylinder of subpost plug 160 correspondence, serves the effect of transformation, speed change
Really.The low speed of the first subpost plug 140 and the second subpost plug 160 moves back and forth the produced heat of friction and is taken away by fluid media (medium),
Avoid the occurrence of heat damage.
Last it is noted that these are only the preferred embodiments of the present invention, it is not limited to the present invention, for ability
For the technical staff in territory, all any modification, equivalent substitution and improvement etc. made within the spirit and principles in the present invention, all
