Overview
CHIJIU S312-120 Constant Speed Stirrer is a laboratory mixing equipment with three-phase AC induction motor and frequency converter speed regulation. Its characteristics are that the motor torque is not affected by Rotation speed, the temperature rise is low, and it adopts a stable structure design with a large chassis and three columns.
Features
1. Adopt three-phase AC induction motor for stable operation.
2. Equipped with a frequency converter for stepless speed regulation, with a wide speed range.
3. The motor torque is not affected by the change of Rotation speed, and the output is stable.
4. The motor temperature rise is low, making it suitable for long-term operation.
5. Adopting a large chassis and a three-column structure, the overall stability is good.
6. The rotating collet has a wide clamping range and is suitable for a variety of stirringrods.
Principle
The Stirrer controls the input Power supply frequency of the three-phase AC induction motor through the frequency converter, so as to realize stepless adjustment of the motor Rotation speed. The motor torque remains constant within the speed regulation range to ensure stable stirring force at different Rotation speeds.
Applications
Chemical synthesis, biopharmaceuticals, materials preparation, food and beverage, Petrochemicals, environmental water treatment, laboratory teaching
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 the setting screws; align the motor plug with the inverter box socket and screw it clockwise into the concave and convex groove to connect, and hear a "click" to indicate locking; it is recommended to install an AC contactor or air switch in front of the power socket.
2. Use operation: Before turning on the power supply, adjust the knob on the inverter box counterclockwise to the minimum; after turning on the power supply, the inverter shows "o", press the green button, and the display shows "0.0"; adjust the knob clockwise, the motor Rotation speed is from slow to fast, and the display window shows the current Frequency; press the red button to stop running; clamp the stirringrod on the chuck, and pay attention to coaxiality.
Notice
• The power supply must be connected to a Three hole socket with protective grounding to ensure safety.
When plugging in or unplugging the motor, the power must be cut off first.
• 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 window does not light up after turning on the power supply, please check and replace the fuse at the bottom of the inverter (according to the original specifications).
• This Stirrer does not allow reverse operation.
• The switch on the inverter box is a backup and is not used by this Stirrer.
• Due to the large starting current of the inverter, the power circuit is recommended to be equipped with an AC contactor or an air switch.
