Structure and working principle:
Speed control part adopts advanced frequency control of motor speed control mode, the use of negative feedback technology, can accurate speed control, the fulfillment of wide range of speed setting and adjustment, and has a variety of display mode, can be directly display speed.
Mixing disc and the interference fit for the stirring shaft, clamp assembly, to ensure the concentric mixing disc and the rotation axis, the motor through dynamic balance test to ensure the motor in the case of A 14000 RPM, the motion of the shaft is not A greater than 0.25 mm.
Latex vessel adopts flexible connection way and bracket to connect, latex vessel and fixed with a cup of Joe rise or fall, limit set along the direction of the post of latex fixed position at the bottom of the container from mixing disc at the bottom of the distance, the instrument has adjusted the location, users do not need to adjust the position of the limit set.
The overall center of the instrument is stable, the support is strong, not easy to deform, the positioning of the container is realized by the positioning block.
