Overview
CHIJIU S312-120 Constant Speed Stirrer is a laboratory stirring equipment with three-phase AC induction motor and frequency converter speed regulation. Its stirring Speed range is 60~ 1400rpm, the chuck can hold a stirringrod of φ 1.5~ 13mm, made of stainless steel, with a large chassis and a stable structure of three columns.
Features
1. Using three-phase AC induction motor, frequency converter speed regulation, motor torque is not affected by Rotation speed.
2. Low temperature rise and stable operation.
3. The large chassis is designed with three columns, resulting in a stable structure.
4. The clamping range of the chuck is wide, ranging from φ 1.5 to 13mm.
5. Adopt stainless steel stirringrod.
Principle
The Stirrer is powered by a three-phase AC induction motor, and the input Power supply frequency of the motor is controlled and adjusted by the frequency converter, so as to realize stepless speed regulation of the motor Rotation speed in the range of 60~ 1400rpm. The frequency conversion speed regulation mode makes the motor maintain a stable output torque at different Rotation speeds.
Applications
Laboratory sample stirring, chemical reaction mixing, solution preparation, material dispersion, etc
Steps
1. Instrument installation: use bolts and nuts to fix the three columns on the chassis; install the motor bracket into the upper slider mounting hole; install the inverter box on the upper end of the long column and tighten it; align the motor plug with the inverter box socket and tighten the lock clockwise.
2. Use operation: Before turning on the power supply, adjust the inverter knob counterclockwise to the minimum; after turning on the power supply, press the green button to start, and adjust the knob clockwise to improve the Rotation speed to the desired value; the stirringrod needs to be clamped on the chuck and pay attention to coaxiality.
Notice
• The power supply must be connected to a Three hole socket with protective grounding.
• Before plugging in or unplugging the motor, the power must be cut off.
• Stirrer should be placed on a flat workbench for use.
• Try to avoid working for a long time at the lowest Rotation speed to prevent the motor from overheating.
• If the display does not light up after power on, please check and replace the fuse at the bottom of the inverter.
• This Stirrer strictly prohibits reversal.
• The switch on the inverter box is a backup, and this machine is not used.
It is recommended to install an AC contactor or air switch in front of the power socket to cope with the large current at the moment when the inverter starts.
