Jj-3 constant temperature electric stirrer intelligent temperature control and stepless speed regulation

1、 Introduction:

  In order to meet the needs of new scientific research projects in modern laboratories, the electric stirrer developed and produced by our factory adopts permanent magnet DC motor and advanced power amplifier circuit. It has the characteristics of stable speed, low noise, large torque and no need to replace carbon brush, It is also equipped with the function of heating and constant temperature, which eliminates the disadvantage that the electric stirrer can not be heated at the same time. It is an indispensable basic equipment for colleges and universities, scientific research institutions, chemical and pharmaceutical units, and is loved by the majority of users.

2、 Parameters and performance
1. Power supply: 220 V, 50 Hz

2. Motor power: 100W

3. Speed regulation range: 0 ~ 3000 rpm stepless speed regulation, adjustable speed.

4. Heating power: 1500W

5. Temperature control range: room temperature - 300 ℃

6. Speed accuracy: ± 1 rpm


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.

4、 Heating operation instructions:
  When using, put the container in the middle of the heating plate forward, and then turn on the power supply. When heating, there should be no water around and at the bottom of the container, so as to prevent the glass cup from bursting due to high temperature heat collection, causing personal injury. Set temperature: press set key to set or view the temperature set point. Press set key once, and the nixie tube character starts to flash, indicating that the instrument enters the setting state. Press the Δ key to increase the setting value, press the ▽ key to decrease the setting value. Long press the Δ key or ▽ key, and the data will change rapidly. Once again, the set key will return to the normal working state, and the temperature setting is completed. The maximum set temperature of the digital display meter is 300 ℃. The temperature can be set according to the water temperature you need. Press set to enter the heating state. When the temperature reaches the set value, it will continue to move upward. This is a normal phenomenon of temperature flushing. Just pay attention to the temperature in the container. If the temperature of water and liquid has not reached the set temperature value, it needs to wait, Because the container is heated by the outside, the surrounding space is large and there is no container for heat preservation, so heating needs a heating buffer period, and the temperature will be naturally uniform after tens of minutes.

5、 Precautions

  The ground wire must be grounded when using. If the mixing rod is not concentric and the mixing is unstable, please turn off the power supply and adjust the clamp to make the mixing rod concentric. The medium speed mixing can reduce the vibration and prolong the service life. The instrument should be kept dry, clean and hygienic.
