At present, CEMF has got ripe designing drawing and test data of 55kW~20000kW (voltage range: 6.3KV~10.5KV) hydro-generator units. Besides, complete estimating and examine procedure of designing has been established according to ISO9001 Quality System. B Technical guarantee CEMF has got ripe technics for 6.3KV and 10.5KV hydro-generator. 1. Gluing technic of high voltage winding turn-to-turn 2. Anti-corona technic of high voltage winding turn-to-turn 3. VPI cacuum soaking paint technic of high voltage winding 4. Babbit alloy casting technic of sliping bearing. 5. Insulation technic between the sliping bearing and the frame. 6. The whole balance technic of the generator’s rotor, runner, flywheel. etc.. C Manufacture condition. The product is been manufactured strictly under the ISO9001 quality guarantee system. 1、The important parts. 1.1. Runner shaft. 1.2. Stator and rotor winding 1.3. Stator and rotor iron core 1.4. Seal parts 1.5. Bearing 1.6. Runner 2、 All of the raw and processed materials, such as steel, silicon piece, electric magnetism line and the main insulative materials, are been stocked from the eligible supplier, and been examed and tested for physics and chemistry strictly according with the the raw and processed materials and the outsourcing parts examining process. before income storeroom, the eligible have the eligible documents income the storeroom according to the , the others can not be adopt or used into the product..
3、 For the machining and the manufacture of the important parts, CEMF carry into the important quality controlling according to the technics provision, and adopt the effective technics method, process controlling, for assurance the product eligibility. Product’s standard :The product according to the national and international standard strictly. D The productive and testing equipments CEMF is equipped with various kinds of equipments and instruments. The total quantity is 1150, including 641 main productive equipments. Complete testing and manufacturing facilities are adopted by CEMF, such as Special Environment Lad. The Center Lab of CEMF is authorized by the Government to supervise quality and inspect commodity of electric machines in Chongqing. The Electric Machine Research institute, and the Electrical Technology.
4、Standards CEMF’s products are strictly designed and manufactured in accordance with nation standards (GB) and international standards(IEC). Its products export to 50 countries and areas. CEMF has good reputation at home and abroad. In 1988, the three-phase asynchronous motors and synchronous generators, which made in CEMF, were honored as perfect products by the Ministry, and gained the praise and prize by water conservancy department of SHICHUAN province、SHANXI province、QINGHAI province and JILIN province. In 1998, CEMF passed ISO9001 quality certification. The technology development and product quality is among the first class in CHINA.
5、Product service CEMF’S product are famed for its reliable drive and super performance. Its product export to 45 countries and areas. CEMF has good reputation at home and abroad. The products sold by CEMF are all strictly examined before leave factory in accordance with relevant nation standard. If you find any quality problem during normal installation and application, we never shift responsibility onto other. And we’ll send technicians to deal with the problems on the spot within 72 hours. On condition that you apply and deposit the products correctly, CEMF is sure that products run well one year of service life(within not more than 2 years from the starting date.).If the product are damaged or can’t run normally because of bad manufacturing quality within the specified time, we’ll repair or replace the parts, even the entire machine without charge. CEMF has got established market net all over China, and there are 21 sale departments in the main cities of China to take responsibility of products’ sales promotion and market developing.
