螺杆料筒拆在一起的方法: Method for disassembling screw barrels of Zhoushan rubber extruder :
1.Turn off the main switch of electric heating, motor and power supply
2.Separate the tail of the screw from the melter motor
3. Knock the lock nut at the end of the barrel loose. (Here the barrel and the machine are connected and fixed in different ways, the disassembly and assembly methods are different, according to actual conditions when disassembling and disassembling). When disassembling here, spray W40 antirust oil.
4. Remove the heating coil heating wire and temperature sensing wire on the barrel. For each heating coil heating wire disassembly, wrap the end of the wire with electric tape to avoid personal injury caused by electricity leakage when the machine is subsequently started. Loosen the heating coil screw and remove the heating coil.
5. Turn on the main power. At this time, adjust the electric heating temperature to the actual temperature displayed on the panel. Start the motor, the two ends of the barrel with the same square iron against the injection barrel, press the injection key, only until the melt motor and the two square iron contact (this process should pay attention to: the two square iron must be horizontal, length * , The length must be greater than the size of the screw tail exposed outside. The feed speed should be slow, when two people cooperate to synchronize)
6. After the top of the barrel is loosened, use a crane to hang the barrel until the barrel is pushed out.
3-5 倍。 Our company can not only process samples and manufacture, but also design, survey and manufacture according to the special requirements of customers, or use bimetal repair for old screws. The service life of bimetal screws is 3-5 times longer than that of ordinary nitriding screws. Times.
