Fig. 2 is the structure chart of the electromagnetic braking part of oil extractor antitheft electric brake of the present utility model；
Fig. 3 is the circuit module figure of oil extractor antitheft electric brake of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings to oil extractor antitheft electric brake of the present utility model, it is described further：
Oil extractor antitheft electric brake of the present utility model, is by housing 1, current transformer 2, controller 3, relay 4
Constituted with electro-magnetic braking device 6, be divided into control section and electromagnetic braking part, control section include housing 1, current transformer 2,
Controller 3, relay 4, and electromagnetic braking part includes electro-magnetic braking device 6 and oil recovery electric motor.
It is divided into controlling of sampling chamber 7 and sealed circuit chambers 8 in above-mentioned housing 1, is installed in controlling of sampling chamber 7
There are three current transformers 2, relay 4（Normally opened relay）, circuit chambers 8 be provided with pressure regulator 9, filter circuit 10 and control
Device 3.
Circuit coupling part is, current transformer 2 be socketed on three-phase power line periphery and respectively by filter circuit 10 with
The circuit of controller 3 couples；The input of pressure regulator 9 couples with three-phase power circuit circuit, output end respectively with filter circuit 10,
The circuit of controller 3 couples；Controller 3 couples with the coil terminal circuit of relay 4, the control end that three phase mains passes through relay 4
Couple with the solenoid circuit in electro-magnetic braking device 6, electro-magnetic braking device 6 is installed on the output shaft one of oil recovery electric motor
End.
The structure of electromagnetic braking is that electro-magnetic braking device 6 includes brake disc 11, braking end cap 12, stress metal disk 13, system
Moving winding 14, brake line ring support 16；Brake line ring support 16, stress metal disk 13, brake disc 11 and the braking ecto-entad of end cap 12
Be socketed on the output shaft periphery of oil recovery electric motor successively, brake line ring support 16, stress metal disk 13 and braking end cap 12 with
The output shaft rotation of oil recovery electric motor, which coordinates and is fixed on oil production machine motor terminal, to be covered, brake disc 11 and oil recovery electric motor
Output shaft fix；Multiple restraining coils 14 are uniformly installed in brake line ring support 16, and stress metal disk 13 passes through tripping spring
