Tube expansion machine for heat exchanger

Machine Overview

This is a kind of tube expansion machine, which is a production equipment of large heat exchanger. It is composed of expander, gantry frame, spring balancer, control system and other parts. The machine uses servo motor as the main drive, and multiple sets of gears are converted to output strong power to achieve stable expansion of copper, aluminum and stainless steel tube.

This expansion machine has 2-12 different combinations of tube for users to choose. You can choose the most suitable machine according to the geometric layout of fin holes of your heat exchanger to meet your efficient production.

The metal rod of this machine has threads. The servomotor drives the screw rod to move forward. There is a metal ball at the top of the screw rod. The metal ball rubs against the inside of tube to expand the pipe. Usually, the maximum length of the metal rod is 6 meters. We also have 10 meters and 20 meters of metal rods for users to choose from.

Advantages of tube expansion machine

• Production process without noise

Due to the lack of a traditional hydraulic station, the maximum noise generated by the servo motor during operation does not exceed 51 decibels. Therefore, the production process of this machine is very quiet, and its noise is equivalent to the fan noise of a desktop computer In industrial production environments, the noise generated by this expansion machine can be completely ignored.

• Efficient and energy-saving

This tube expansion machine uses a 2.5kw servo motor, with a maximum speed of 1800 revolutions per minute. After 1:10 gear conversion, its fastest production speed is 3 meters per minute. Moreover, this machine is an indirect production type, and the motor does not rotate when the machine stops, which does not consume electricity during this time. Therefore, this machine is very energy-efficient, with a 35% reduction in energy consumption compared to traditional hydraulic station driven expansion machines.

• Geometric layout of multiple workstations

Since there are many tube pitches in the heat exchanger industry, in order to meet the diversified requirements of users, we have designed a variety of tube layouts for this machine to meet the production needs of users. If your heat exchanger is unique, we can also provide customized services without charging additional design service fees.

• Very good cost performance ratio

Because our tube expansion machine has realized mass production, and every part is produced in batches, we are absolutely competitive in terms of price compared with our competitors, and the fastest delivery time only takes 3 weeks.

Advanced functions of tube expansion machine

1. The touch screen multilingual page is also one of the highlights of this machine. Usually, we have built-in Chinese and English languages for this machine. Of course, we can also set the language you need, such as Russian, Spanish, French, Portuguese, etc.

2. The metal ball adopts a flexible design that can be replaced. Users can replace the metal ball at a very low cost to expand metal tube of different diameters. This ingenious design can save the factory owner a lot of costs.

3. This tube expansion machine adopts the most advanced intelligent control method. Users can set the required length size on the touch screen to achieve precise control of the movement of the metal rod, with a maximum tolerance of no more than 0.01mm.

4. Built in multiple production modes, engineers can easily cut the working mode of this machine according to production needs, meeting the quality requirements for producing different heat exchangers.

Installation and precautions

Because the control system and motor of the machine are separate during transportation, when the power is first connected to the machine, the touch screen will display a warning. You need to set the raw data for the servo motor of this machine. We will provide instructions and video tutorials. By watching this video tutorial, you can easily set it up, and you only need to set it up once for this tube expansion machine.

If you replace the metal threaded rod, you need to cut off the power supply of the machine. This is for safe operation of the machine and to prevent workers from accidentally touching the button switch, which may cause production accidents.

The main purpose of this tube expansion machine is to produce large heat exchangers. You want to reserve enough space for it. If your heat exchanger tube is 5 meters long, you may need to reserve 11 meters of space for it.
