Automatic Hydraulic Heat Exchanger Pipe Expander Machine
Core Purpose & Application Value
This Automatic Hydraulic Heat Exchanger Pipe Expander Machine is a high-precision, high-efficiency special equipment tailored for the heat exchanger manufacturing industry, with the core purpose of expanding the pipe of heat exchanger coils. Relying on stable hydraulic drive technology, it realizes precise diameter expansion of heat exchanger copper tubes, ensuring tight and seamless fitting between copper tubes and heat exchange fins, tube sheets and other components, which directly improves the sealing performance, heat conduction efficiency and service life of heat exchangers.
As a mainstream hydraulic pipe expansion equipment, it combines the stability of a Horizontal Tube Expander Machine, the mobility of a Mobile Expander and the convenience of a Portable Heat Exchanger Expander, making it suitable for household air conditioning heat exchangers, industrial chillers, HVAC systems and other heat exchanger coil processing scenarios, meeting both batch production and on-site maintenance needs.
Main Technical Parameters
The machine is equipped with optimized hydraulic control system and mechanical structure, featuring high adaptability and stable performance, with core main parameters as follows:
- Applicable Copper Tube Diameter: Φ7-Φ25mm. This diameter range covers all mainstream copper tube specifications of heat exchanger coils, compatible with thin-walled and conventional copper tubes. The hydraulic expansion force is evenly output, avoiding tube cracking, deformation and dimensional deviation during the expansion process, ensuring uniform forming of each tube, and perfectly adapting to the processing needs of various standard heat exchangers.
- Expansion Length: Customizable according to buyer's requirement. The machine adopts adjustable mechanical fixture and intelligent hydraulic control design, which can accurately locate and control the expansion length, whether it is short-distance end expansion or full-section long-tube expansion. It can be flexibly adjusted according to different heat exchanger models and structural designs, fully meeting personalized and customized processing requirements.
- Expansion Speed: 5-11meter/ min. Equipped with high-efficiency hydraulic power system and stepless speed regulation function, the expansion speed can be adjusted freely according to tube diameter, material and precision requirements. It balances high-speed production efficiency and high-quality processing effect, realizing continuous and stable pipe expansion operations, greatly improving the production efficiency of heat exchanger assembly lines.
Machine Design & Model Selection
The machine adopts a humanized and practical structural design, integrating durability, operability and flexibility, and launches diversified models to match different production scales. There are one tube, two tube, four tube design for users to choose, each model inherits the core advantages of hydraulic stability and horizontal operation of the Horizontal Tube Expander Machine, and retains the mobile transfer performance of the Mobile Expander.
- Single-tube design: Compact structure, small footprint, simple operation and easy maintenance. It is suitable for small-batch processing, trial production and maintenance scenarios, and can also be used as a flexible Portable Heat Exchanger Expander for on-site processing.
- Two-tube design: Dual-station synchronous expansion design, double the processing efficiency compared with single-tube type, balancing production efficiency and space cost. It is the preferred choice for medium-scale heat exchanger manufacturers, with stable operation and high cost performance.
- Four-tube design: Four-station linkage hydraulic control, equipped with automatic positioning and feeding auxiliary mechanism, realizing high-speed synchronous expansion of four tubes. It is designed for large-scale standardized batch production, maximizing production capacity and reducing unit processing cost, suitable for large heat exchanger production bases.
