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.
