Is the Low Output of the Plastic Granulator Related to the Voltage?

May. 07, 2020

As a Central Plastic Granulator Suppliers, share with you. The influence of the voltage on the plastic granulator is usually a problem that is relatively easy to ignore. If the voltage is too high or too low, the motor of the plastic granulator is easily burned out, which is easy to cause the output of the plastic granulator to decrease and the power of the motor. Reduced, so the impact of voltage on the plastic granulator is relatively large, especially when machinery is used without a special transformer installed, so the voltage must be controlled at -5% or + 10% of the rated voltage of the plastic granulator to be normal operation.

Plastic Granulator current test method: When the running current measured by the clamp ammeter is equal to or close to the rated current of the motor, it means that the rated load of the motor is reached.

Know the coefficient and tangent value of the motor drive equipment, convert the calculated current, when the measured current reaches the calculated current, it is considered that the operating torque full load of this equipment has been reached.

When the clerk frequency is constant, the voltage level will directly affect the starting characteristics of the plastic granulator.

When the power supply voltage is too low, the rotating magnetic field generated by the stator winding of the motor is weakened because the electromagnetic torque is proportional to the square of the power supply voltage. Therefore, if the starting torque of the motor is insufficient, it will cause difficulty in starting the motor, and the value of the increase in the load current component will be greater than the value of the decrease in the excitation current component. Therefore, the stator current increases the power loss and increases the time too long, or even burns the motor.

When the voltage is too low, the motor speed decreases, and the heat dissipation of the fan decreases, resulting in heat generation. If blocking occurs, the motor is easily burned. If the voltage is too low, it will burn the motor of the recycled plastic granulator.

At the same time, too high voltage will cause the stator magnet of the motor to pass the saturation state, and the current will increase sharply, the efficiency of the motor will decrease and the heat will be serious.

The cleaning process of the barrel of the plastic granulator production line usually uses refueling to achieve the cleaning effect. Before cleaning, it is necessary to grasp the materials stored in the barrel and the thermal stability of the raw materials to be replaced, various plastic parts, compatibility, molding temperature, etc. Technical materials, master the correct operation steps and essentials when cleaning, so as to save time and material consumption.
