Below the abominable condition such as environment of radioactivity of domain of 2. chemical industry or environment of high temperature radiate, with without bearing electric machinery sealed pump undertakes flotsam is handled, can solve the difficult problem that mechanical bearing wears away and maintains. In chemical industry, right effective and sealed the demand that transmit and produces a system rises further, the sealed pump with traditional sealed runner shaft, mechanical bearing needs to lubricate, cause as a result of sealed invalidation according to reporting the breakdown of 80%% is, 20%% is bearing, join and other breakdown. For safe production, spare environmental pollution, use sealing pump without bearing report secret is optimal choice. Current, engineering college of federal of Su Li world and cooperation of Sulzer pump company finished power to be 30kW without bearing the development of sealed pump prototype and test work, entered try moving phase.
Domain of 3. life science
The heart is life always motive, once malfunction hard repair. Use artificial heart part or replace heart function to make the good news that life of heart disease patient continues entirely. The hematic pump that uses mechanical bearing can arise to chafe and give out heat, make hematic cell damaged, cause haemolysis, cruor and thrombus, endanger patient life even. The does not have drive of electric machinery of bearing permanent magnetism blood pump of engineering college of federal of Su Li world and success of Levitronix company development and can transplant the heart left ventricle inside human body assists device to had been in clinical medium applying.
Consider and apply foreground
Our country begins train of magnetism in suspension and magnetism bearing research old, from 20 centuries 90 time later period, jiangsu university, Shenyang industry university and Nanjing aerospace university got national science foundation is aided financially early or late, began study the work without bearing electric machinery, a few result were obtained in theory and face of true proved recipe. Jiangsu university is electric information project institute Qiu Yurui of bright red 熀 person engineering college of federal of Su Li world Professor J.Hugel waited to begin power to be 4kW jointly without synchronism of bearing permanent magnetism electric machinery studies and use the job, captured sensor detects, the crucial technology difficult problem such as power loss, successful development goes the first power to be 4kW without chip of bearing permanent magnetism electric machinery, predict to will wait in chemical industry, semiconductor industry this year get applied.
The country waits in the United States, Japan, be in without bearing electric machinery the domain such as industry of industry of life science, pharmacy, chemical industry industry, semiconductor, food industry got applied. Develop further as our country economy, the drive that in a lot of special electric drive the domain is sure to change a tradition and transmission means, quality of expensive to carrying product, reduce it is cost, important to reduce pollution to will rise action. Accordingly, market of very big potential application is had without bearing electric machinery in our country, begin the research that does not have bearing electric machinery and application actively to have reality and far-reaching sense.
