The need for sustainable economic development of polyurethane insulation pipes

The need for sustainable economic development of polyurethane insulation pipes

The current development trend of direct buried thermal insulation tube CNC machine tools is high speed, high precision, composite machining and multi-axis linkage. However, further developments focus not only on the improvement of machine tool technology performance, but also on the harmony of machine tools with the environment and users. High performance, green, intelligent integration and integration can create a new situation for future-oriented high-performance CNC machine tools.

In the past 10 years, the world's leading machine tool manufacturers have been committed to the improvement of the technical performance of CNC machine tools, constantly surpassing each other and launching dazzling new products. For example, composite machining machines, parallel motion machine tools, inverted machining machines, ultra-precision machine tools, etc. It can be predicted that in the next 10 years, machine tool manufacturers and R&D institutions will compete for the commanding heights in the relationship between machine tools and the environment and people, and form new products of “super-off” competitors, such as e-machine tools and green machine tools to adapt to the industry. The need to transform and upgrade and develop a low-carbon economy.

Energy conservation and emission reduction are the mission of the 21st century industrial production and the need for sustainable economic development in China. China is a major machine tool producer and consumer in the world, with about 7 million machine tools. If you save 1kWh per unit per day, it will be possible to save more than 2 billion kWh of electricity throughout the year. The main measures for implementing energy saving and emission reduction for existing machine tools and moving towards green manufacturing are as follows:

(1) Most of the machine tools in China are old and have a long service life and are in disrepair. The idle running power measurement should be carried out on machine tools that have been in service for more than 5 years, and the machine tools with low operating efficiency and high energy consumption should be overhauled or scoured.

(2) The production efficiency of the machine tool comes from the tool tip, using advanced tools and reasonable cutting parameters, reducing the energy consumption required to cut off the unit volume of the chip, or increasing the value created by the unit energy consumption.

(3) Optimize the NC program by means of the programming software. The polyurethane insulation tube keeps the tool path as continuous as possible, reducing the sudden change of the direction and speed of the movement to reduce the energy consumption of the drive motor.

(4) Energy management of the machine tool, using low-energy and high-efficiency auxiliary devices such as hydraulic, pneumatic, lubrication and cutting fluid to reduce the energy consumption of the non-cutting process and timely turn off the power supply of the auxiliary equipment.

(5) Cutting fluid is an indispensable auxiliary material for the use of machine tools, and it is also a major source of pollution. With the advancement of tool coating technology, dry cutting will gradually be applied. Currently, the use of micro-lubrication technology (MQL) is the preferred solution to promote green manufacturing.
