Industrial Special Valves

January 24, 2018 by Leave a Comment

https://korean-machinery.com///inquiry[INQ. NO. 1801M09] Since its establishment in 1992, Total Engineering Co. has been committed to localizing valves. In particular, the company has been contributing to the development of the Korean valve industry by localizing various special valves that were imported. They won the Presidential Commendation for the development of excellent capital goods at the end of last year through the localization of a ram piston valve.
In the early 1990s, there were many valve makers in Korea at the time, but special valves requiring high technological power were all imported. Therefore, Sung Hae-jin, CEO of Total Engineering started his business in 1992 with a partner with long experience and know-how in the valve industry with the aim to localize special valves that Korea had to import with domestic technology”.
Since the establishment of Total Engineering, thanks to the company’s steady efforts, its products and technologies were gradually recognized and the company was able to register itself as a vendor for Daelim Industrial. As a result, the company became able to supply its products to large companies such as LG, Samsung, GS and Hyundai. In 1995, Total Engineering succeeded in localizing and commercializing various special valves including a ram piston valve, one of its flagship products. During this period, the company acquired an ISO 9002 certificate in 1999 and an ISO 14001 certificate in 2005 through constant efforts to improve quality. In 2007, it established a second factory to cope with increasing orders. Since then, Total Engineering transformed itself into a joint-stock corporation in 2011 and since then, has been growing steadily.
According to President Sung, Total Engineering produces various special valves such as knife gate valves, ram piston valves, diverter valves, tank bottom flush valves, self lapping valves, change-over valves, blind valves, 3-way ball valves and strainers. Among them, a double knife gate valve is one of the representative gate valves, mainly used for transfer lines for ash and slurry from mills at power plants. There are three types – metal-to-metal seats, metal-to-rubber cushion seats and metal-to Ptfe-seats. Total Engineering also holds a patent for long knife gate valves.
Next, ram piston valves are installed in reactors that involve a main process for production of petrochemical products, and are manufactured to transport petrochemical products from inside reactors and collect samples. This ensures perfect sealing even at high pressure of 1,500LB or more and requires a high level of technology to completely shut off gas. For this reason, only a small number of companies in the world can supply ram piston valves to major markets and Total Engineering is rivaling these companies in the global market.
Finally, blind valves allow maintenance and repair work by completely blocking the flow of fluid. This product features a structure to minimize fluid resistance and design and production to withstand high pressures.

Couplings, Clamps

January 17, 2018 by Leave a Comment

https://korean-machinery.com///inquiry[INQ. NO. 1801M08] Founded in 1995, Jung Woo Coupling, a small company, manufactures couplings and clamps to connect pipes. However, the company has been recognized as a small but strong company in exporting to 35 countries including Japan, the USA, the UK, France, Norway and Australia.
Couplings connect two pipes and are mainly used for the installation of pipes. Clamps are used to fix or overlay pipes on other pipes for maintenance purposes. Couplings and clamps are recognized as products that can replace existing cumbersome and difficult piping connections such as welding. If a user only locks bolts on couplings and clamps, the user can easily connect pipes, thereby saving the user work time and cost.
Couplings and clamps can be used in a variety of industries including shipbuilding, power generation, chemical, petroleum, housing, and construction. Couplings and clamps are already widely used in Europe such as the UK and Germany, but not in Korea.
For this reason, Jung Woo Coupling is known as the best manufacturer in the field of couplings and clamps in Korea. “With only one or two companies producing pipe couplings and clamps in Korea, our company feels a sense of responsibility as a leading company in Korea,” remarked Yoo In-tae, CEO of Jung Woo Coupling. “In particular, we are proud of the fact that we are recognized around the world as we have invested in research and development over the past 16 years.”

Jung Woo Coupling has concentrated its research efforts on improving quality and technology since its establishment. The company registered four utility models by applying their own technology to foreign products. As an example, Jung Woo Coupling improved the compression of saw teeth of pipes’ connection parts of couplings to prevent leaks and improve connection strength.
In addition, the company made products that can be used only for straight pipes available for “ㄱ-shaped” pipes, and enhanced product performance so that pipes made of different materials can be connected. That is to say, they made installation work easier by developing assembly-type couplings that connect large sewer pipes that pass through cities and small sewer pipes for homes.
Compared to this technology, Jung Woo Coupling products are about 30% cheaper than those of overseas major manufacturers. Jung Woo Coupling secured cost competitiveness through quality management by reducing cost through quality certification and reducing expenses incurred in the production process.

Air Compressor Energy-saving Controller VSD+ Series

January 10, 2018 by Leave a Comment

https://korean-machinery.com///inquiry[INQ. NO. 1801M04] Dotech Inc. specializes in controllers for the field of environment measurement and refrigerating and air-conditioning, stands out in the energy-saving solution market starting with the industrial air compressor energy-saving controller VSD+. The inverter controlling type that minutely controls the number of rotations of the compressor motor with a frequency is one of the qualified energy-saving technologies that are being rapidly introduced to home appliances. The air compressor that the inverter technology is applied from this perspective has been more widely used these days in the global market due to its high performance and energy efficiency.
However, though it is rarely used in Korea because for industrial air compressors, it accounts for more than 30% of the entire energy expenses of the site and replacing with the air compressor due to energy consumption and energy efficiency is burdensome in terms of the financial side, as well as the site operation aspect. Dotech’s VSD+ is the product that can be a groundbreaking solution to these problems.

 

Introducing the energy-saving controller

As industrial energy can be used more inexpensively than general energy, in the industrial equipment design, energy consumption was not considered important even until a few years ago. However, as problems related to energy overconsumption and environmental destruction become an issue worldwide, the industrial equipment market started to show increased interest in energy-saving equipment. Dotech understood market demands early and has coped with it from a long-term perspective. Products developed in recent few years are being manufactured as an energy-saving type based on Dotech’s own precision control technology. In particular, the product that receives attention among energy-saving controllers of Dotech is the air compressor energy-saving controller VSD+ series. The air compressor is a device consuming the most electricity in the general manufacturing facility. The key point of the high efficiency air compressor is the compressor control applying the inverter. It is a qualified energy-saving technology with rapidly increasing usage in the air compressor field as well as the refrigerating and air-conditioning field.

 

 

The VSD+ series is receiving attention

It can save power consumption significantly by properly adjusting the number of rotations of the motor of the air compressor suitable for the usage of compressed air by controlling the inverter. The VSD+ series is the outer mounted controller maximizing energy efficiency by changing the control type (Y-△) to the inverter control oriented VSD (Variable Speed Control) type by installing on the general industrial air compressor. Because most existing air compressors cannot control the speed of the internal motor, it cannot avoid unnecessary energy consumption as it is operating at almost 100% output regardless of the usage of air to maintain the mobility stand-by status. On the other hand, if applying the VSD+, the device’s operation efficiency can be increased significantly by finely controlling the number of rotations of the compressor according to the usage of air in real-time. In particular, for the fields where no-load operating time is long or load and no-load operating is working frequently in turn, up to energy can be saved up to 30~40%. Calculating the annual electricity rate for the case of operating the 100-horsepower air compressor for 8,000 hours after installing the VSD+, approximately KRW 19.7 million and 19,008 ton CO2 (based on 75kW, load factor 60%, electricity charge KRW 120) can be saved compared to pre-installation. It can succeed in killing many birds with one stone, including reduction of electricity charges, extension of life of major parts, reduction of CO2, etc., by removing unnecessary operation of the device. Under ordinary circumstances, the installation fee can be recovered in 1~2 years with energy-saving costs.

 

Based on 100-horsepower compressor (75kW), load factor (60%), operation (8,000hours) and electricity charge (KRW 85)

 

Competitiveness of Dotech and VSD+

One of the most important advantages of Dotech is high customer reliability. In fact, there have been no exchange and refund compensation cases until today since the product was released and on sale. It means Dotech provides the best production environment by analyzing data of a company’s energy consumption precisely. The biggest advantage of installing the VSD+ on an old device, compared to a new device with the inverter applied, is that it does not need to replace a device. If replacing an old device with a new device because of energy consumption, losses can occur not only in the price of the product itself but also in various parts. The VSD+ is an innovative solution that can reduce the purchase cost, as well as resulting losses, by increasing energy efficiency of the existing facility to the level of the new device while maintaining its status unchanged. Development of the VSD+ is more meaningful since more than 80% of domestic manufacturing sites operate old devices. As the VSD+’s energy-saving examples in the manufacturing site goes viral now, it is receiving a lot of attention from the industry. Furthermore, Dotech was awarded the 2016 National Sustainability Management Grand Prize (national sustainability management technological innovation sector) and the 2016 Korea Small to Medium-sized Business Grand Prize as the excellence of its energy-saving technology gained recognition.

NC Index Table

January 10, 2018 by Leave a Comment

https://korean-machinery.com///inquiry[INQ. NO. 1801M03] Daeshin Machinery Co., Ltd. was established on August 15, 1997, and is operating two business divisions at present. The first division is the automobile business division, which is supplying products to Hyundai Motor Company since starting to mass-manufacture automobile parts (oil, pump housing, carrier, and knuckle) after building the automatic processing line in 2002 for the first time.
The second division is the NC Index Table division. At the time of building the automatic processing line in 2002, Daeshin Machinery introduced and applied another company’s index table to production, but the index table on the market was not structurally appropriate for used article cutting due to the product’s characteristic (for used article cutting). Therefore, Daeshin Machinery researched the NC index table maintaining high stiffness autonomously and developed an index table applying the face gear clamp method for the first time after much trial and error. This face gear clamp method has cutting torque ten times stronger than the methods of other companies.
Since it established a separate division in 2006, Daeshin Machinery has supplied products to customers after autonomously completing the entire process from production to quality inspection, assembly, and installation test. In 2017, Daeshin Machinery realized 0.01° of the dividing angle by applying the disk clamp method, supplementing the disadvantage (the dividing angle 0.5°) of the face gear. As this technical prowess won recognition, the company was registered as the appointed company for supply of the NC index table for Hyundai-Wia last year.
In general, the NC index table is composed as a jig, which is the part fixing a processed article on the table. It is installed on the vertical NC milling process bed. The table is rotated by a servomotor. It has a main function that is clamped on the configured location by an internal clamp structure so various processing parts (angles) of the material are placed on the location, where it can be processed automatically, by rotation of the table. Furthermore, since various processed products are placed on the NC index table jig safely, products can be processed simultaneously and mass-manufactured easily. Also, it aims to reduce the production cost by improving the product cycle by reducing the processing process by realizing various processing angles by driving the axis of rotation.
Daeshin Machinery is originally a user of the NC index table. Daeshin Machinery registered a utility model (registration No. 20-0456169) by autonomously developing the face gear clamp type maintaining high stiffness appropriate for used article cutting. This has cutting force ten times stronger than those of other companies with the same specifications. It also has excellent repeatability and is appropriate for processing parts for used article cutting aimed at mass-production. Moreover, a minute dividing angle (0.01°) is available by applying the disk clamp type, supplementing the disadvantage of the face gear clamp type, at the same time.
