Overview
QIWEI JFS - 550/2.5 L high-speed variable frequency Disperser is a dispersion equipment that integrates stirring, sand grinding and dispersion, and is suitable for different experimental needs in the laboratory. The equipment adopts variable frequency motor, which has the advantages of small size, low noise, no commutation interference, no carbon brush mechanical abrasion, etc. The motor Power is 550W, the digital direct display of the rotating shaft Rotation speed, and is equipped with a dispersion impeller and a sand grinding blade.
Features
1. Using variable frequency motor, small size, low noise, no commutation interference, no carbon brush mechanical abrasion;
2. Double axis constant force lifting system, easy to lift;
3. The smart frequency conversion controller realizes stepless speed regulation, the digital PID technology has high control accuracy, and the 4-digit digital tube directly displays the spindle Rotation speed;
4. The dispersed impeller and sand grinding blade disc are directly connected with screws for easy replacement;
5. The left and right clamps fix the barrel, the cylinder body is a jacket structure, which can be processed by chilling down water and stainless steel;
6. With timing function, wide speed range (60~ 8000rpm);
7. Optional 5-liter double-decked Mixing Tank.
Principle
The JFS-550 high-speed frequency conversion Disperser drives the shaft through the frequency conversion motor, uses the smart frequency conversion controller to realize stepless speed regulation, and applies the digital PID technology to precisely control the Rotation speed. The dispersed impeller or sand grinding blades are directly connected to the shaft, and the high-speed swirl/spin in the material realizes the functions of stirring, grinding and dispersing.
Steps
1. Plug in the power supply, the meter shows normal;
2. Turn the potentiometer knob to the left to the bottom;
3. Press the "RUN" button on the panel, and the motor is ready to run;
4. Adjust the potentiometer knob or press the “▲”/“▼” key until the desired Rotation speed;
5. Press the "STOP" button to stop the motor from running.
Notice
• Rotation speed greater than 4000r/min should not be empty;
• Before use, make sure that the holder is fixed to the barrel, and the barrel cover hole is in line with the motor shaft;
• Rotation speed adjustment to avoid sudden high-speed start;
• Regularly check the motor and connecting parts to ensure that they are not loose.
