FJQY-300-A Pneumatic hydraulic tube expander machine

Introduction 

Pneumatic hydraulic tube expansion machine is developed by our company, which is specially used for rapid and high-strength expansion of tube plate and heat exchange tube. The system is composed of gas driving station, high voltage connection electronic control transmission system and expander. The driving force of the system is compressed air, the expansion working medium is water, and the expansion working pressure can be precisely set to meet the various needs of the expansion pipe. This machine has automatic water adding function, easier to operate; More suitable for thick wall tube heat exchanger, condenser, cooler, boiler and other fields of adhesive expansion and sealing expansion.

Technical principle

The hydraulic tube expander used in domestic hydraulic expansion technology is composed of high-strength alloy steel core rod and imported elastic rubber resistant to high pressure, integrated design, can withstand ultra-high pressure without the use of seals, easy to use, high work efficiency, working principle is shown in the figure. It uses the high-pressure hydraulic pressure provided by the pipe expansion machine to apply the radial pressure generated by the high-pressure elastic rubber body to expand the pipe plate. When the ultra-high hydraulic pressure enters the high-pressure elastic rubber body through the high-strength alloy core rod, the high-pressure elastic rubber body generates radial pressure, which is enough to make the pipe material plastic deformation, so as to realize the expansion between the pipe and the tube plate.
