【摘要】：某艦船電機(jī)轉(zhuǎn)軸發(fā)熱量非常大,為了保證電機(jī)能夠正常平穩(wěn)的工作,采用了氟利昂進(jìn)行冷卻,但這種物質(zhì)會對大氣臭氧層構(gòu)成嚴(yán)重的威脅,因此,氟利昂的密封問題至關(guān)重要。另外,軍方要求在艦船發(fā)生故障時,必須保證在電機(jī)轉(zhuǎn)軸和整個電機(jī)部件不拆卸的情況下完成密封件的更換。由于傳統(tǒng)密封無法滿足零泄漏、長壽命、高可靠性等要求,而磁性液體密封完全能滿足這些要求。所以本課題的目的是設(shè)計適用于該艦船電機(jī)轉(zhuǎn)軸冷卻介質(zhì)密封的磁性液體密封方案： 本論文針對這一目標(biāo),完成了以下研究： (1)在學(xué)習(xí)分析和思考磁性液體密封的基礎(chǔ)上,在國內(nèi)外首次提出了分瓣式磁性液體密封的概念； (2)建立分瓣式磁性液體靜密封和旋轉(zhuǎn)密封模型,結(jié)合磁性液體Bernouli方程和邊界條件,推導(dǎo)分瓣式磁性液體靜密封和旋轉(zhuǎn)密封耐壓公司 (3)設(shè)計適用于艦船電機(jī)轉(zhuǎn)軸的分瓣式磁性液體旋轉(zhuǎn)密封方案,完成其中各密封部件的選材及具體結(jié)構(gòu)設(shè)計計算； (4)用ANSYS對該分瓣式磁性液體密封結(jié)構(gòu)進(jìn)行了二維靜態(tài)磁場的仿真分析； (5)完成分瓣式磁性液體密封可行性驗證實驗,包括：選擇適用于分瓣式磁性液體旋轉(zhuǎn)密封的密封介質(zhì),分瓣外套的粘接,分瓣外套的密封檢漏實驗等； (6)完成分瓣式磁性液體密封件的整體裝配,進(jìn)行了分瓣式磁性液體靜密封耐壓實驗,并且在靜密封基礎(chǔ)上進(jìn)行了旋轉(zhuǎn)密封的推導(dǎo),
[Abstract]:In order to ensure the motor to work smoothly, Freon is used for cooling, but this substance will pose a serious threat to the ozone layer in the atmosphere. Therefore, the sealing problem of Freon is very important. In addition, the military requires that in the event of ship failure, the seal must be replaced without disassembly of the motor shaft and the entire motor component. The traditional seal can not meet the requirements of zero leakage, long life and high reliability, but magnetic liquid seal can fully meet these requirements. So the purpose of this paper is to design a magnetic fluid seal scheme which is suitable for the cooling medium seal of the motor shaft of the ship. The following studies have been completed: (1) on the basis of studying, analyzing and thinking about magnetic fluid seal, the concept of valve magnetic fluid seal has been put forward for the first time at home and abroad; (2) establishing the static seal and rotating seal model of magnetic fluid, combining the Bernouli equation and boundary condition of magnetic fluid. The valve type magnetic fluid seal and rotary seal pressure-resisting company (3) is derived to design the disc magnetic fluid rotary seal scheme which is suitable for the rotor shaft of the ship motor, and the material selection and the concrete structure design calculation of the sealing parts are completed. (4) the two-dimensional static magnetic field is simulated and analyzed by ANSYS. (5) to complete the feasibility verification experiment of the valve magnetic fluid seal, including: selecting the sealing medium suitable for the rotary seal of the valve type magnetic fluid, bonding of the split jacket, sealing leak detection experiment of the split jacket, etc. (6) complete the integral assembly of the valve magnetic liquid seal, carry on the pressure resistance experiment of the split magnetic liquid static seal, and on the basis of the static seal, carry on the derivation of the rotary seal.
