Electric stirrer jj-4ab quadruple independent speed measurement and speed regulation intelligent digital display temperature control mixing

1、 Brief introduction of jj-4ab quadruple asynchronous speed measuring constant temperature electric stirrer

  In order to meet the needs of laboratory staff, jj-4ab is based on jj-1 electric stirring. There is an original electric stirring, forming a joint manufacturing of four electric agitators. 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 the advantages of stable speed, high torque, low noise and high speed Digital display intuitive, and with heating and constant temperature function, 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
Motor power: 100wx4
Timing range: 0-120min
Speed regulation range: 0-3000r / min
Speed measurement range: start-up - 3000rpm
Constant temperature range: room temperature - 100 ℃
Temperature control accuracy: ± 0.5 ℃
Temperature fluctuation: ± 0.1 ℃
Heating power: 1000W
Working size: 610x160x130mm
Speed display: the minimum speed data is the stirring start data

Speed measuring motor: the speed measuring motor is a current controlled single-chip microcomputer for accurate speed measurement. There is no error in the speed measurement. If the current is unstable or the voltage is too high or too low, the fluctuation of the speed will be affected, but the experiment will not be affected. [if accurate constant speed mixing is required, it can be selected: constant speed constant function, additional cost, please explain with the sales department when purchasing]

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 1500-2800 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 grounding wire must be used. If the mixing rod is not concentric and the stirring is 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.
