hydraulic tube expander machine for heat exchanger

hydraulic tube expander machine outline

This hydraulic tube expander machine is the key machine for producing large industrial heat exchangers. It mainly expands the tubes of the heat exchanger, so the tubes and fins are tightly combined to achieve a rapid cooling effect.

The machine is controlled by PLC, touch screen, and other control systems. The compressed air drives two high-pressure liquid booster pumps to transfer the high pressure to the inside of the pipe, to expand the pipe.

The tube expander machine can quickly change tools, produce pipes with different outer diameters, expand a copper pipe with a diameter of 25mm and a length of 5m, and the pressure rise time can be completed in a few seconds

advantage

1. To produce heat exchangers of different sizes, only two tools need to be replaced, and its cost is very low

2, The hydraulic tube expander machine can realize silent production, and the operators do not need to wear ear covers

3. The size of row spacing and Column spacing does not restrict the expansion of one tube at a time. That is to say, only one side of the outer diameter of the tube of the heat exchanger needs to be matched, and other dimensions need not be considered

4. The power supply of the machine is 220V, and the actual use is 24V, which is very power-saving

5. The expansion liquid medium of the hydraulic tube expander machine is ordinary tap water, which has no pollution

Working principle

Step 1, install the tools on both sides of the tube

Step 2, Press the start button of the machine, and the hydraulic tube expander machine will automatically exhaust the air inside the pipe

step 3, the machine will automatically expand the pipe according to the set pressure, and after completion, the machine will discharge the tap water inside the tube

Step 4, remove the tool from both sides of the tube, At this point

the expansion of the pipe is complete, The entire expansion of this hydraulic tube expander machine is relaxed and pleasant, and it not only has good work efficiency but also does not cause pollution to the environment
