1. Medium concrete mixer Mixing control system
The Medium concrete mixer electronic control system controls the mixing system by controlling the main drive motor of the large concrete mixer. For large-capacity concrete mixers, due to the large power of the mixing motor and the large starting current, the mixer starts frequently. Direct start requires that the motor capacity is less than 20% of the power capacity.
2. Medium concrete mixer Lift limit control system
The Medium concrete mixer lifting limit is the key equipment in the concrete mixer, and it is the guarantee of the reliability of the mixer. The lifting mechanism usually uses a two-stroke switch in series, the front stroke switch is used as a rising stop switch, and the latter is used as a safety limit switch and alarm switch.
3.Drop limit control system
In order to prevent the Medium concrete mixer hopper from falling to the bottom of the pit and the loose transition of the steel wire rope, the lower limit control equipment needs to be installed. When slack, the travel switch on the load top beam starts the frame, and the lifting motor stops automatically.
The electrical control circuit of the Medium concrete mixer is equipped with an air switch, a fuse, a thermal relay with short-circuit protection, overload protection, and phase failure protection. All control buttons and air switch handles and indicators are arranged there. lock. The electrical components in the distribution box are installed on the iron plate, which is safe, reliable, and easy to operate and maintain.
