The first two blogs introduced eight main features of continuous lead extruders. This blog will introduce the features of the remaining main components (take the YQL-Φ100 / 5 continuous lead extruder as an example):
9. Rear Water Cooling System
It consists of cooling water spraying pipe and subsequent spraying pipe for stainless steel laundry, which can make the second cooling for the crystallization of lead layer and crystallized lead sheath at the exit of die.
At the rear of laundry is mounted air compressed wiper to dry the surface of lead sheath.
10. Flow Controller (including full automatic auxiliary system)
The cooling water pumped out of the bottom of the machine enters into the extruding barrel in 3 lines through 3 glass rotameters in coordination with the heaters, inlet water is adjusted by manual which can control the process temperature of extruding barrel.Flow meter is equipped with the valve for adjustment, and on it water flow on each cooling point of machine can be read.
Proportional valve for full automatic auxiliary system is Siemens, China
11. Electrical Control System
Touch screen exchanges data in dual ways through PLC, controls and monitors the system via PLC process. Output of PLC is transmitted to each speed regulator to control and monitor status of each device to carry out control in computer.
