The HAE series laboratory shear emulsifier is driven by a compact series-type micro-high-speed motor and is suitable for mixing low to medium and high viscosity liquids in laboratories or pilot workshops, and crushing granular materials shearing emulsification in liquid media. The machine is composed of a high-speed motor, a shearing and emulsifying working head and a speed controller. The drive host adopts high-quality engineering plastic and die-cast aluminum alloy as the body, which ensures stable operation; the working head is made of high-quality stainless steel and has a wide range of experimental applications; the operating speed is controlled by a microprocessor, which can instantly and effectively compensate for speed changes caused by load changes and power supply voltage fluctuations; constant speed is reliable. The built-in soft start and automatic over-cut protection ensure the safety of the experiment at full load and continuous operation for a long time. The stepless adjustment of the speed allows the mixing speed to be corrected at any time during the experiment. Real-time numerical display of voltage, frequency, current, output power, output torque, etc. provides convenience for experimental data collection. The running timing control function ensures that the timing of the experiment is effectively controllable.
