SJZ Series Vertical Extruder Gearbox Introduction
SJZ Series Conical Double Screw Gearbox feature:
The gears are made of high strength alloy steel. The gear goes through the process of carburizing quenching heat hardening and gear grinding to achieve the precision of grade 6, The whole unit is small volume, high carry capacity, stable drive, low noise and high efficiency. The material of the box is made of high quality ductile iron. After casting, full stress treatment is carried out with high strength and beautiful appearance. All oil seals are imported, and the high speed shaft is treated with oil seal and mechanical seal, and the oil leakage rate is low. Using external forced lubrication and brazing plate heat exchanger, the cooling and lubricating system is reliable, the operating temperature is low, and the daily maintenance is convenient.
Features of SJZ Series Vertical Extruder Gearbox
1.Adopt high grade alloy with case-hardened technology for gears and pinions. Hardness of teeth surface reaches as high as 54-62 HRC, grinding precision reaches grand 6.
2.Compact structure, reliable operation, stable transmission, strong load capacity, large range of output torque, extensive power coverage.
3.Excellent heat dissipation, impact resistance, low noise, long service life.
4.The main standard parts, like bearing and oil seal, adopt domestic high-quality brand products, and also can use imported products according to customer's request.
SJZ Series Vertical Extruder Gearbox can be used in PVC double pipe production lines for producing PVC conduil pipe, diameter from 16mm to 40mm, 16mm to 63mm. it consists of SJZ series extruder, double pipe mold, double pipe vacuum tank, double pipe drawing and cutting machine, stacker. It can produce two pipe at one time to achieve higher production efficiency.
