nameHV416 SPINNING EXTRUDERS Post Date :2008-05-19 Expire Date :2009-05-19     View Basket Detailed Trade Lead Description NO：HV416 Product：HV416 SPINNING EXTRUDERS Introduce：·A double-grade high precision helical gear reducer is employed to ensure smooth running, lower noise and long service life. ·A large thrust bearing is used for support of the output shaft to counter the axial thrust load from the screw. ·Either pin type or prism type mixing head can be chosen for the screw head to meet the requirements of different materials. ·Either D.C. conversion moter of A.C. conversion moter can be chosen for driving system. ·Imported electric elements are used for both D.C. drive and A.C. conversion drive with precision being controlled within±1％, so that melt pressure can be kept constantly. ·The close-loop control system is employed for temperature control with control precision being 0.5℃. Computer-controlled communication system is employed for the whole machine, so that all parameters can be preset, amended or monitored by means of the touch screen and control panel. ·In the separation type extruder, the melt stays shorter time inside the melting cylinder, so that melting quality can be ensured and the output quantity can be 20% more than that of normal screws having same specitications. The electric control system employs tri-close-loop type, with speed and pressure being controlled automatically, and alarming and power cut-off being effected automatically in case there is over pressure inside the screw head or there is over load of electricity, so that the whole machine runs reliably and safely. Purpose：The machine is mainly used for spinning with chips in synthetic fibre production. Chips are melted evenly and the melt is extruded constantly and uniformly with controlled output quantity at a suitable temperature and pressure to meet the requirement of spinning industry. Parameter：screw dia. (mm): 60 length-diameter ratio: 24 speed range (r/min): 20-100 Max. output (kg/h): 80-90(polyester) heating power (kw): 13.5 driving power (kw): 22 heating power (kw): 5 Max. head pressure (Mpa): 15-25 capacity (ton): 1.75 Remarks： 1. Specifications of HV416 derived types are the same as those of the basic type. 2. Central height will be decided by the customers. 3. Screws and cylinders with different specifications can be manufactured as per the requirements of the customers. 4. SHP411-130×32 is a separation type screw extruder.
