Brief description of the drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is mounting structure schematic diagram in this embodiment.
Embodiment:
Referring to Fig. 1, this embodiment adopts following technological scheme: pumping unit power fails protection brake control circuit, and described brake control circuit comprises break control unit for controlling break, for controlling the Electromagnetic Control unit of break control unit and playing the time delay control unit of time-lag action;
Described break control unit comprises a transformer B who is connected with the input end of brake control circuit and the first diode D1, the output terminal of the first described diode D1 is connected with the input end of solenoid valve M3 normally opened contact KM1-1 by A.C. contactor KM1 first, and the output terminal of solenoid valve M3 is connected with the output terminal of brake control circuit normally opened contact KM1-2 by A.C. contactor KM1 second; The output of described transformer B is provided with bridge heap Q1, described bridge heap Q1 output positive voltage terminal is connected with the second diode D2 input end, bridge heap Q1 output negative voltage side is connected with the output terminal of solenoid valve M3, and the output terminal of the second diode D2 is connected with the input end of solenoid valve M3;
Described Electromagnetic Control unit is included in the A.C. contactor KM1 and the time relay normally-closed contact JS1-1 that between the input end of brake control circuit and output terminal, connect;
Described time delay control unit is included in time delay relay JS1 between the input end of brake control circuit and output terminal.
Upper also in parallel the solenoid valve M3 of described solenoid valve M3.
The working principle of this embodiment is: energising: A.C. contactor KM1 coil obtains electric, first couple of normally opened contact KM1-1 of A.C. contactor KM1, second couple of closed solenoid valve M3 that connects of normally opened contact KM1-2,380V voltage DC160V after one way rectifier opens solenoid valve M3; The about 50A of work transient current, meanwhile, the time delay of time relay JS1 coil starts, (tentative 0.4S).Delay time arrives, the disconnection of time relay normally-closed contact JS1-1, A.C. contactor KM1 coil blackout, its first couple of normally opened contact KM1-1, second couple of normally opened contact KM1-2 disconnect, solenoid valve M3 high pressure dead electricity, two solenoid valve M3 keep attracting state under bridge heap Q1 output low voltage DC 12V power supply simultaneously, and operating current is about 10A.
Power-off: whole circuit dead electricity, solenoid valve M3 dead electricity resets, lock braking.Energising repeats said process again.
As shown in Figure 2, brake control circuit is arranged in circuit box 1, brake control circuit is connected with break 2, break 2 is arranged on control oil machine motor 3, in the time of break 2 no electric circuit in closed state (normally closed), in the time that electromagnet is switched on, yoke produces strong magnet attraction armature compact disc spring, by lever system, brake slipper is separated to both sides, break 2 discharges (declutching): in the time of electromagnet power-off, and yoke loss of excitation, armature resets under the effect of dish spring, by lever system, brake slipper is resetted rapidly, arrester close (braking).
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
