When beam hanger is risen in place, the 4th pressure switch 13 collection signal, has gone up in place, the 4th solenoid valve 16 is closed as signal is shown
Close, do not rise in place, it is necessary to supplement pressure oil such as, then the 3rd solenoid valve 18 is powered, and mends pressure oil, treats the 4th pressure switch 13
After gathering signal display rising in place, the 3rd solenoid valve 18, the 4th solenoid valve 16 are closed；At this time on the sucker rod of the second oil cylinder 14
Extreme higher position is raised to, the sucker rod of the first oil cylinder 11 drops to extreme lower position.
When the second oil cylinder 14 sucker rod decline when, the first oil cylinder 11 sucker rod rise at the same time, second solenoid valve 9 is powered
It is powered in oil return position, the 4th solenoid valve 16 and is powered into oil level, the 5th solenoid valve 6, the pressure oil of the second oil cylinder 14 enters first
In oil cylinder 11, the sucker rod of the second oil cylinder 14 is gradually reduced, the sucker rod of the first oil cylinder 11 synchronously rises；The pumping of second oil cylinder 14
When beam hanger is fallen into place, the 3rd pressure switch 15 collection signal, the 5th solenoid valve 6, the 4th solenoid valve 16 are closed；First oil cylinder
When 11 sucker rod is risen in place, second pressure relay 12 gathers signal, such as signal display rising in place, second solenoid valve 9
Close, do not rise in place, it is necessary to supplement pressure oil such as, then the first solenoid valve 7 is powered, and mends pressure oil, treats second pressure relay
After 12 signals are shown in place, the first solenoid valve 7, second solenoid valve 9 are closed.The sucker rod of the first oil cylinder 11 rises to highest at this time
Position, the sucker rod of the second oil cylinder 14 drop to extreme lower position.
Repeat above-mentioned circulation, you can realize the alternation of the first oil cylinder 11 and the second oil cylinder 14, the first oil cylinder 11 and the
The load of two oil cylinders 14 counterweight each other, belongs to balance-type type balancing work mode, and motor 1 is in long-time low-load, and the short time is high
During the alternation of load, such a mode work efficiency is higher.
It should be noted that above-mentioned the first solenoid valve 7, second solenoid valve 9, the 3rd solenoid valve 18, the 4th electromagnetism referred to
Valve 16, the 5th solenoid valve 6, the 6th solenoid valve 19, first pressure relay 10, second pressure relay 12, the 3rd pressure relay
Device 15, the 4th pressure switch 13 are and controller（Not shown in figure）It is electrically connected, and above-mentioned parts is moved by controller
It is controlled, these are all the prior arts and are well known to those skilled in the art, therefore are no longer retouched in detail one by one here
State.
