1.Expanding two-stroke machine is the production of large dedicated heat exchanger equipment essential Expander. This machine expands single hole or 2 holes once, adjusting stroke length of expanding rods can finish the expanding joint of certain length heat exchanger, also as important tool of trial-produce and repairing of heat exchanger.
2.This machine is consist of expanded joint (gear case), flare tool, hydraulic pressure station, electronic control box, portal frame (plain trolley) and balancer (60kg), to be a complete system with 4 hydraulic tubes and 2 controlling wire.
3.Expanded joint (gear case) mainly constitutes “V” shell, cycloid hydraulic motor, transmission gear, rolling gear, guide clamp device and expanding rods.
4.Hydraulic pressure station constitutes oil case, oil pump, Solenoid valve, oil pump motor, Relief valve and other hydraulic spares.(hydraulic components use YUKEN product.)
5.Electrical parts such as intermediate relay, thermal relay and operating button are imported from Japan. |
