Below, three screw pelletizer manufacturers to give you a brief introduction about the use of three screw pelletizer what need to pay attention to?

1, the main motor and the oil pump motor have electric interlock, that is, the motor of the oil pump does not start, the main motor can not start, the main motor does not stop, and the oil pump motor can not stop.

2, when the head pressure exceeds the set alarm value, the material pressure alarm signal lights up and automatically stops.

3, the main motor and feed motor have electrical chain, that is, the main motor does not start, the feeding motor can not start; the main motor of the feeding motor does not stop, the main motor can not stop. The main motor control cabinet has over current protection and has been set before the factory. In addition, it also has a mechanical protection device, usually a nylon shear pin type safety coupling. When the torque is exceeded, the shear pin is cut off and the gearbox stops working.

The 4 and three screws are controlled by frequency conversion, AC motor drive or DC speed regulation and DC motor drive. The deceleration and the three screw drive are in the same box, and the dimensions are compact. The safety couplings equipped with shear pins can protect the screw and transmission box from damage due to overload.
