Figure 2: The latest workshop

From the initial telephone communication, to multiple face-to-face exchanges and on-site inspections, to the comparison of multiple companies, a set of negative pressure centralized filtration equipment was tailored for the current situation of Danfoss Tianjin. The 25 machining centers on site were uniformly transported, cooled, filtered, and supplied through the sewage pump overhead pipeline. The process is as follows:

In the machining process, equipment, tools, fixtures and workpieces constitute a complete process system, and cutting fluid is one of the key factors. Because cutting fluid can reduce cutting temperature, reduce tool wear, extend tool life, improve workpiece surface quality, and reduce processing costs. For Danfoss Tianjin, due to the short production period, high precision and complex processing technology, each equipment is in high-speed cutting operation, which puts higher requirements on the use of cutting fluid. "Danfoss Tianjin's production workshop density is high and the production scale is large, so centralized filtration and treatment of cutting fluid is a very ideal choice." Mr. Zhang Yujie, technical support of Yantai Keeyun Machinery Co., LTD., told reporters

The cutting fluid purification equipment provided by Yantai Keeyun for Danfoss Tianjin provides cutting fluid with stable temperature for processing equipment in high operation. While taking away iron chips, it ensures that the cutting fluid does not contain particles with a diameter greater than 50μm and does not contain any miscellaneous oil. "Our cutting fluid purification equipment can not only filter iron chips, but also recycle and reuse the cutting fluid, which maximizes the efficiency of cutting fluid use and ensures the effective management of emulsion stock in the production workshop." Mr. Zhang Yujie introduced.

Provide customers with the most suitable solutions
Yantai Keeyun's cutting fluid purification equipment has the advantages of fully automatic operation, stable performance, high filtration accuracy, and can improve processing technology, improve the surface processing quality of workpieces, and extend the service life of cutting fluids. At the same time, Yantai Keeyun will also formulate corresponding plans according to the characteristics of customers themselves, providing customers with high-quality equipment while providing good after-sales service guarantees. Since its establishment in 2000, Yantai Keeyun has always focused on clean production and environmental protection, and has been working hard in the industry to provide customers with system solutions and turnkey projects for clean production of cutting fluids. Yantai Keeyun cooperates with many well-known companies including Danfoss Tianjin and has a good industry reputation, which makes Danfoss Tianjin full of confidence in Yantai Keeyun's equipment.

After cooperating with Yantai Keeyun, Danfoss Tianjin's production site has been significantly improved: because the cutting fluid purification equipment has filter cloth to complete the filtering work, and the filtering accuracy is high, iron filings with a diameter of more than 25μm will be filtered, which prolongs the life of the cutting fluid, improves the surface finish of the workpiece, reduces the equipment failure rate, ensures that the pipeline will not be blocked, and facilitates the on-site staff to perform daily maintenance of the equipment. At the same time, it also reduces the wastewater discharge rate, improves the air quality of the workshop, and reduces production costs.

Under the guidance of Mr. Wang Haiqing, the reporter visited the latest workshop of Danfoss Tianjin, which is being prepared. Here, the reporter has a deeper understanding of the green and environmentally friendly production concept that the Danfoss Group has been promoting. Although the workshop as a whole is still under construction, many equipment with environmental protection functions have been installed in place in an orderly manner. "Because the previous cooperation was very smooth, we decided to continue to use Yantai Keeyun's cutting fluid centralized industrial filtration equipment. In this new workshop, we mainly produce the most popular heat pumps and SH295 vortexes in the market, so Yantai Keeyun's cutting fluid filtration equipment will have a larger application space." Wang Haiqing said.

"Cutting fluid purification is one of the important guarantees in the operation of processing equipment. The equipment that completes this work plays a very important role in the production process. As an enterprise at the forefront of industry development, Yantai Keeyun is well aware of its responsibilities. We always put customer needs first and continue to innovate existing technologies and equipment in order to provide more domestic and foreign customers with high-level technical support and services." Mr. Zhang Yujie added.

As a global leader in the field of energy conservation and environmental protection, Danfoss Group has played an active role in promoting the development of low-carbon economy in countries around the world. Yantai Keeyun will rely on its many years of application experience to help Chinese customers move towards green and clean production. It is precisely because of the coincidence of the two in energy conservation and emission reduction that the cooperation between the two companies will become closer and closer.

Reporter's Postscript:
The interview in Tianjin was on a sunny afternoon. Although the visit to Danfoss (Tianjin) Co., Ltd. was not long, the reporter has seen the inclusiveness and adaptability of Danfoss Group as a global enterprise, and also the sense of responsibility and commitment of Yantai Keeyun as a local Chinese enterprise. We can believe that the strong combination of the two companies will definitely bring more innovative technologies and surprises to the industry.
