Abstract

The utility model relates to a crucible shaft lifting control system of a solar silicon single crystal furnace, which comprises a dial switch, a PLC (Programmable Logic Controller), a relay, a first DC motor, a second DC motor and a driver electrically connected according to a logic rule. The dial switch and the PLC realize that one DC motor simultaneously has the functions of high speed and low speed and two DC motors respectively have the functions of high speed and low speed. When the two DC motors respectively realize the functions of high speed and low speed, the contact on-off state of the relay is controlled via PLC, and the switching between the low-speed rotation of the first DC motor and the low-speed rotation of the second DC motor is realized. The crucible shaft lifting control system has simple structure, cost saving and convenience for use.

Embodiment:
Shown in Figure 1; Toggle switch (1) is connected with PLC (2) input; PLC (2) output is connected with rly. (3) coil, and the output torque of driving mechanism (4) and feedback line are received first contact (3-1) of rly. (3), second contact (3-2) respectively; The 3rd contact (3-3); On the 4th contact (3-4), the 6th contact (3-6) of rly. (3), the 8th contact (3-8), the tenth contact (3-10), the 12 contact (3-12) are connected with second direct-current machine (6), and the 5th contact (3-5) of rly. (3), the 7th contact (3-7), the 9th contact (3-9), the 11 contact (3-11) are connected with first direct-current machine (5).
When toggle switch (1) breaks off; Be to be failure to actuate in normal make war (11) of toggle switch input; Be normally open; Not adhesive of transfer relay power winding (13) at a slow speed soon; Rly. (3) is failure to actuate, and the output torque of driving mechanism this moment (4) links to each other with the 11 contact (3-11), the 9th contact (3-9), the 7th contact (3-7), the 5th contact (3-5) of rly.
