Four electric stirrer jj-4a digital display speed and speed adjustable synchronous mixing

1、 Introduction:

  In order to meet the needs of laboratory staff, jj-4 is based on jj-1 electric stirring. There is an original electric stirring, forming a joint manufacturing of four electric agitators for synchronous mixing. The design is reasonable and the structure is novel. It adopts brushless DC motor, stepless speed regulation, and uses advanced power amplifier circuit. It has stable speed, high torque, low noise and revolution The display is intuitive, easy to operate and safe. It is an essential basic equipment for colleges and universities, scientific research units and chemical engineering units.

2、 Technical parameters:

Working power supply: 220V50 Hz
Power: 400W
Timing range: 0-120min
Speed regulation range: synchronous starting 0-2500r / min
Speed measurement range: start-up - 2500rpm
Speed display: the minimum speed data is the stirring start data

3、 How to use it

  First of all, support the mixing rod on the motor shaft clamp, and adjust the speed control knob to the lowest speed position, place the solution to be stirred in the center of the mixing bar, turn on the power switch, and select the required time or normally open when timing operation is required. If the stirred solution is dilute, the speed can be adjusted to 500 rpm. If the viscous solution is viscous, the speed should be adjusted to 1500-2500 rpm. The stirring speed of liquid with high viscosity is faster, and that of liquid with low viscosity can be slower. Speed can be adjusted according to their own needs, speed control mode: stepless speed regulation.

4、 Precautions

1. The ground wire must be grounded when using. If the mixing rod is not concentric or unstable, please turn off the power supply and adjust the clamp to make the mixing rod concentric.

2. Medium speed stirring can reduce vibration and prolong service life. The instrument should be kept dry and clean.
