the installation of dry gas seal by drilling a vent drilling dry gas seal positioning Boss Boss to seal damage destruction of Up to 25 mm 10mm 7mm see Figure 1 in the F resulting in dry gas seal targeting local plastic ring seal bad Left and right to cover their own water pressure test the pressure for the 30 M Pa after passing the cover and chassis pressure test done at the same time pressure to 20 MPa medium for helium The product of the media for circulating hydrogen gas under pressure 16 MPa if not sealed Boss Welding not only affects the appearance quality is more important to the functioning unit will be sealed leak caused a serious but will also affect gas The use of sealed leading to paralysis and crew shutdown process the consequences would be unthinkable Left and right cover material for KMN materials the special material very difficult Welding the left and right cover has been finished if Welding improper measures will cause cracks after welding deformation the most serious is the result of the ponents scrapped Figure 1 Cover Welding regional plans 2 KMN briefing materials KMN material is my pany centrifugal pressor impeller welding end caps and other special materials The material for chromium molybdenum alloy solder needed before preheating after welding need to heat treatment in the use of statequality plex welding process welding materials used KMN dedicated electrode 3 Welding Methods Laser 31 cold welding As left and right cover has been finished dry gas seal targeting Taiwan has finished processing welding heat input will lead solder after deformation To prevent deformation after welding welding is the preferred method of cold welding In order to ensure the quality of Welding the author and the Chinese Academy of Sciences Institute of metal surface laser fusion of professional and technical personnel the quality of the scene can be used to confirm whether the cold welding method Welding Laser fusion welding surface of the technical staff to cover KMN of performance welding etc are familiar Welding position in the middle of the cover to confirm the repair welding electrodes when contact is very difficult even if exposure to welding electrodes Efficiency is very low quality is difficult to ensure that in the face of this situation it is not appropriate to confirm the 。 蓋盤傾角θ 115176。 β 1 26176。 56176。 50176。 14

強度計算所涉及的內容是在氣動計算結果的基礎上針對設計要求進行相關的校核主要是判斷在壓縮機高速旋轉時由于葉輪和軸的過盈配合而產(chǎn)生的應力是否能夠滿足機器安全運行的許用應力要求以便于保證在機器正常運行時每一點的應力小于許用應力 本體設計主要是壓縮機具體結構設計尤其是尺寸確定其主要包括定子和轉子兩大 部分的設計重點是根據(jù)氣動計算強度計算的結果確定主軸推力軸承支撐軸承平衡盤進氣蝸室排氣蝸室的具體尺寸從而使機器能夠達到氣動強度等方面的設計要求 關鍵詞 Abstract The design of the turbine type pressor is concrete is large aromatics deviceBCL609 turbo centrifugal pressor This design mainly includes the air operated putation the strength calculation the main body to design and so on several parts What air operated putation design is the flow channel part what the design mainly uses is principles and so on velocity triangle law Eulers equation carries on the design calculation The strength calculation design is mainly for examines when pressor high speed revolving as a result of the impeller and the axis the stress which the full coordination produces whether can satisfy the machine safe operation the allowable stress Guarantee when machine normal operation each spot stress is smaller than an allowable stress Strength calculation here no longer in detail explained The main body
