鋼波紋管先從軸(zhou)(zhou)向用(yong)M4螺釘(ding)固定(ding)(ding)在定(ding)(ding)位環上(shang),再用(yong)m螺釘(ding)從直徑方(fang)向將定(ding)(ding)位環固定(ding)(ding)在軸(zhou)(zhou)套(tao)上(shang),這(zhe)樣就(jiu)存在累計誤差,不易確保(bao)鋼波紋(wen)管端面垂直于軸(zhou)(zhou)套(tao)。壓(ya)蓋上(shang)沖刷油和冷卻(que)(que)水注入孔位置不合理,冷卻(que)(que)水的通徑有(you)一(yi)半孔被靜(jing)環密封(feng)圈擋住(zhu)。
The steel bellows is fixed on the locating ring with M4 screw from the axial direction, and then the locating ring is fixed on the shaft sleeve with m screw from the diameter direction, so there is accumulated error, and it is not easy to ensure that the end face of the steel bellows is perpendicular to the shaft sleeve. The location of flushing oil and cooling water injection hole on the gland is unreasonable, and half of the cooling water diameter hole is blocked by the static ring seal ring.
形(xing)成靜環(huan)冷卻(que)水減少(shao),密(mi)封面冷卻(que)效果不好;沖刷(shua)油孔離(li)動、靜環(huan)密(mi)封面太(tai)遠(軸(zhou)(zhou)向間隔太(tai)長),使沖刷(shua)油不易注入到(dao)鋼(gang)波紋管密(mi)封處。直徑偏小鋼(gang)波紋管內徑62mm,密(mi)封比壓偏大;軸(zhou)(zhou)徑為(wei)55mm,軸(zhou)(zhou)套外徑為(wei)60mm,壁(bi)厚(hou)僅(jin)為(wei)2.5mm,壁(bi)厚(hou)偏小,簡(jian)單(dan)變(bian)形(xing),形(xing)成拆、裝困難。
用(yong)戶柜(ju)子(zi)中(zhong)心的孔的直徑≥2.5cm,由(you)于金屬管(guan)兩側的接(jie)頭(tou)比(bi)中(zhong)心軟(ruan)管(guan)厚,而且用(yong)戶柜(ju)子(zi)的一(yi)些眼(yan)睛僅(jin)夠(gou)假如(ru)裝置要(yao)求用(yong)戶事前打孔或重(zhong)新(xin)打孔以方(fang)便波紋管(guan)穿過則軟(ruan)管(guan)要(yao)經過。一(yi)些用(yong)戶原來的天(tian)然氣界面(mian)十分接(jie)近(jin)大理石臺(tai)面(mian)。
金屬管(guan)界(jie)面(mian)需要具有(you)程度(du)的曲率,較小曲折面(mian)積≥30mm。假如曲率小于上述大小,則無法暫(zan)時(shi)裝置。該(gai)界(jie)面(mian)位于用戶家的一(yi)角(jiao),而且被單獨(du)阻止。存(cun)在潛(qian)在的安全(quan)隱患(huan),需要在裝置前進行(xing)糾正(zheng)。請(qing)檢(jian)查接(jie)頭是(shi)否(fou)別離卡住以及是(shi)否(fou)能夠運用扳手(shou)(扳手(shou)長度(du)為20cm)。
鋪裝于壩基下的金屬波紋管的管身要設定預埋拱度,其尺寸革命老區基土很有或許出現的下移量,涵底橫坡和回填土高寬比等要素綜合性考慮到,一般能為長度的百分之零點六到百分,不適合超越百分之二,以確保管路中心不出現凹現或山體滑坡。//hanihanbj.com/
