2.5x2.5x3m Drying And Curing Oven Of Transformers

Technical solution:

1, Introduction to the working principle and purpose of the HB series standard transformer oven:

This oven is a transformer specific drying equipment for hot air circulation and automatic intelligent control of the entire process. A large air volume, low noise, and temperature resistant centrifugal fan is installed on the top of the oven, and the heating chamber is set in the air ducts on both sides of the inner liner. During operation, the lower part of the left and right air ducts (about 1/3 height) is used in the studio to supply air vertically upwards, allowing all external parts of the workpiece to be heated simultaneously; After sufficient heat exchange between the hot air and the workpiece in the studio, it evenly flows back to the top suction chamber, and then is sent to the two side air ducts (heating chambers) by the fan for further heating, repeating the process. Due to the use of high air volume and high air pressure circulating fans for forced hot air circulation, good temperature uniformity is ensured in the studio. Ensure that the temperature inside the oven meets the process requirements.

This equipment has the characteristics of high temperature control accuracy, simple operation, energy conservation, safety and reliability, etc. It is widely used in the transformer industry for the impregnation drying (curing) process of transformer coils and the curing use after epoxy casting.

The HB series oven is mainly used for drying and curing of transformers and transformers

2, Our company's product advantages and preferential policies for customers:

2.1. Excellent insulation performance - According to the JB/T5520-91 standard, for drying boxes with a maximum working temperature not exceeding 200 ℃, the surface temperature shall not exceed room temperature+35 ℃. Our company adopts special high-quality materials and special insulation production processes to ensure that the surface temperature of the box body shall not exceed room temperature+15 ℃;

2.2. High Temperature Uniformity - According to the JB/T5520-91 standard, "the temperature uniformity of the electric blast drying oven shall not exceed ± 2.5% of the highest temperature" (for this oven, ± 2.5% x 200 ℃=± 5 ℃). Based on the production process of the transformer and the placement method during drying, our company optimized the matching of circulating air volume and air duct structure, and improved the temperature uniformity in the furnace to within the range of ± 3 ℃;

2.3. Electric heating tube warranty for three years - heater is the heart of heating equipment! We have chosen a surface low load electric heating tube, which has the advantages of large heat dissipation area, fast heating speed, low surface temperature, and not easy to oxidize. It is durable and has a three-year warranty;

2.4. After sales service - We provide a one-year warranty and free maintenance for our company's products. We visit customers irregularly at least twice within a year, and the equipment is repaired for life. Only material cost fees are charged for repairs

3, The performance and characteristics of the HB series transformer dedicated oven:

Adopting the AI518 intelligent temperature controller from Xiamen Yudian, a Sino foreign joint venture, with PID parameter self-tuning, solid-state relay+cycle controller contactless continuous power adjustment, the entire baking process is automatically completed after the process parameters are set, which can meet any curing curve requirements, is easy to operate, and has stable and reliable performance. Selecting electrical control components from well-known domestic and foreign manufacturers to achieve optimal reliability of the curing furnace electrical control system. An additional over temperature alarm protection system is installed, which automatically cuts off the heating power supply and emits sound and light alarm reminders when the temperature inside the furnace is abnormal, effectively protecting the safety of products and equipment. Adopting a more reasonable hot air cycle for plastic products, making the temperature inside the oven and product sintering more uniform, resulting in better results. The heating element adopts a low load U-shaped electric heating tube, which is resistant to oxidation, stable in performance, and has a long service life. The bottom of the electric blast oven is equipped with a track and adopts a trolley in and out structure, making it easy to load and operate. The insulation material adopts high-quality aluminum silicate cotton with low thermal conductivity, which has a significant energy-saving effect

WxiJiniu Machinery Co.,ltd. formerly known as Wuxi Metallurgical Machinery Factory, registered trademark for "Jinqiu" brand, was founded in June 1969. It is in Wuxi city, 150 kilometers far from Shanghai city. We have been to stated enterprise, since 2002, we recombined to private company, and got fast development, we are one big group now, our group mainly produces hydraulic press brake, hydraulic shears, coiling feeding line--especially for aluimnum cap making, slitting line, cut to length, transformer machines....and other series product. It is one of the earliest factory in China to make these metal sheet machines.

The company covers an area of 62,000 square meters with 300 people. It has advanced production equipment’s with imported large CNC gantry milling machine, imported large CNC boring and milling machine, 100-ton carriageway and a series of iconic devices. Our excellent design team can make personalized products according to the users’ demands. At the same time, we have established long-term cooperation with some famous university, such as Jiangnan university, Nanjing University, Jiangsu University. Through our research staff innovation and hard work, we have received dozens of patents. At the same time, we have ISO and CE certifications.

In the domestic market, we set up many offices in different cities, Beijing, Kunming, Hefei…And to the international market, in many countries, we have sales and service agent, USA, Peru, Brazil, India, Russia…. Our engineers have been to those countries to install our machines. Because of our machine good quality and good after-sales service, the customers give us very high commend.

We hope to set up very good and long cooperation with more customers around the word.
