The circulating water of the cooling system of the twin screw extruder barrel should use distilled water or demineralized water. Be sure to use water from another source. The screw can only be opened at low speed, and the idling time cannot exceed two minutes. After feeding, the rotating speed can be gradually increased only after the material is discharged from the die hole of the standby head. When the pressure of the machine head exceeds the set value, the material pressure alarm signal light will light up. An alarm will be issued and the machine will stop automatically.
Disassembly and assembly of material temperature thermocouple and pressure sensor of twin screw extruder. When there is material in the head of the twin screw extruder, it must be heated. Assembly and disassembly can only be carried out after the material has softened. There is also an electrical interlock between the feeding motor and the main motor. That is to say, when the main motor of the feeding motor does not stop, the main motor cannot stop either. When the main motor does not start, the feeding motor also cannot start. The main motor control cabinet of the twin screw extruder has the function of overcurrent protection, which has been set before leaving the factory and does not need to be set again. In addition, the double screw extruder also has a mechanical protection device.
When the twin screw extruder is running, be sure not to bring any metal impurities into the raw materials used for production. There is an electrical interlock between the oil pump motor and the main motor. That is to say, when the main motor does not stop, the oil pump motor cannot stop either. If the oil pump motor does not start, the main motor cannot start.
The high speed of the twin screw extruder can improve productivity and has unique advantages when processing heat-sensitive and high-viscosity materials.
When making masterbatches and changing colors, it only takes a few minutes to quickly open the barrel for manual cleaning. The twin screw extruder factory tells everyone that in this way, the cleaning material can be reduced and the cost can be saved. It has a very wide range of applications and can be applied to the processing of a variety of materials. Twin screw extruder can achieve high efficiency and high quality.
The twin screw extruder is easy to open and you can find out the wear degree of the bushing and threaded components in the barrel at any time. And then carry out effective replacement or maintenance, so as not to worry about failure and cause waste. When repairing the twin screw extruder, it is only necessary to loosen a few bolts, turn the handle of the worm gear box and lift the upper half of the barrel to open the entire barrel. Its maintenance is very convenient, which saves maintenance time and reduces work intensity.
