離心泵是磁力泵的主導(dǎo)產(chǎn)品，磁傳動回轉(zhuǎn)位移泵雖有25年的歷史，僅近七八年在設(shè)計制造水平以及大扭矩能力方面才有廣泛的基礎(chǔ)。重點是磁力傳動齒輪泵與螺桿泵，大傳動能力達400Nm,轉(zhuǎn)速3500r/min時功率為150kW。近年來永磁傳動技術(shù)已從泵類向其它密封機械擴展，技術(shù)上集中于提高設(shè)備的可靠性、抗介質(zhì)腐蝕新材料的研究，流體技術(shù)及制造裝配的精度。磁力泵代表著一個制造技術(shù)的水平，近年來工業(yè)發(fā)達的磁力泵在效率、壽命、制造周期、成本、可靠性等方面有了突破性的進展。為滿足國內(nèi)外市場需要，石油化工公司成套設(shè)備向大型化發(fā)展，我國必須有一批年產(chǎn)千萬噸級的煉油廠、百萬噸級的乙烯裝置。機械裝備要滿足重負荷、長周期、低能耗，并符合環(huán)保要求。我國在仿制國外產(chǎn)品中發(fā)現(xiàn)，制造磁力泵的材質(zhì)和工藝要求是很高的(圖\文www.ds128.cn/)。 中譯英： Centrifugal pump is the dominant product of magnetic pump, magnetic drive rotary displacement pump has a history of 25 years, only nearly seven or eight years in the design and manufacture level and large torque capacity is a broad base. Focus on magnetic transmission gear pumps and screw pumps, the maximum transmission capacity of 400Nm 3500r/min power 150kW, speed. In recent years, magnetic drive pumps have been from to other seals mechanical expansion, technology is focused on improving the reliability of equipment, resistance to corrosion and new materials research, fluid technology and manufacturing assembly accuracy. Magnetic pump represents a national manufacturing technology level, in recent years developed industrial countries in the efficiency of magnetic pump, life, the manufacturing cycle, cost, reliability and other aspects of a breakthrough. In order to meet the needs of domestic and foreign markets, Petrochemical Corporation of complete sets of equipment to large-scale development, our country must have a number of annual production capacity of tens of millions of tons of oil refineries, megaton ethylene device. Machinery and equipment to meet the heavy load, long period, low energy consumption, and comply with environmental requirements. China in imitation of foreign products found in the production of magnetic pump, material and technical requirements is very high.
