鋼波紋管先從(cong)軸向用M4螺(luo)釘(ding)(ding)固(gu)定(ding)(ding)在(zai)定(ding)(ding)位(wei)環上(shang),再(zai)用m螺(luo)釘(ding)(ding)從(cong)直(zhi)徑方向將定(ding)(ding)位(wei)環固(gu)定(ding)(ding)在(zai)軸套(tao)上(shang),這樣(yang)就存(cun)在(zai)累計誤差,不(bu)易(yi)確保鋼波紋管端面垂直(zhi)于(yu)軸套(tao)。壓蓋上(shang)沖(chong)刷油和冷(leng)卻(que)水(shui)注入孔位(wei)置不(bu)合理,冷(leng)卻(que)水(shui)的通(tong)徑有(you)一半孔被靜環密(mi)封圈(quan)擋住。
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.
形成(cheng)靜環冷(leng)卻水減少(shao),密封(feng)面冷(leng)卻效(xiao)果不(bu)好;沖(chong)刷(shua)油孔離動、靜環密封(feng)面太遠(軸(zhou)向(xiang)間隔太長),使沖(chong)刷(shua)油不(bu)易注入(ru)到鋼(gang)波紋管(guan)(guan)密封(feng)處。直(zhi)徑(jing)偏小鋼(gang)波紋管(guan)(guan)內徑(jing)62mm,密封(feng)比壓偏大(da);軸(zhou)徑(jing)為(wei)55mm,軸(zhou)套外徑(jing)為(wei)60mm,壁(bi)厚僅為(wei)2.5mm,壁(bi)厚偏小,簡單變形,形成(cheng)拆(chai)、裝困(kun)難。
用(yong)戶柜(ju)子(zi)(zi)中心的(de)孔的(de)直徑≥2.5cm,由于金屬管兩(liang)側的(de)接(jie)頭比中心軟管厚,而(er)且(qie)用(yong)戶柜(ju)子(zi)(zi)的(de)一(yi)些眼睛(jing)僅(jin)夠(gou)假如(ru)裝置要(yao)求用(yong)戶事前打孔或重新打孔以方(fang)便波(bo)紋管穿過(guo)則軟管要(yao)經(jing)過(guo)。一(yi)些用(yong)戶原來的(de)天然(ran)氣(qi)界面十分接(jie)近大理石臺面。
金屬管界面(mian)需要具有程(cheng)度(du)(du)的(de)曲率,較小(xiao)曲折面(mian)積≥30mm。假如曲率小(xiao)于(yu)上述大小(xiao),則無法暫時裝(zhuang)置。該(gai)界面(mian)位于(yu)用(yong)戶家的(de)一角(jiao),而(er)且被單獨阻止。存在(zai)潛(qian)在(zai)的(de)安全(quan)隱患(huan),需要在(zai)裝(zhuang)置前進行糾正。請檢查接頭(tou)是否(fou)別離卡住(zhu)以(yi)及(ji)是否(fou)能夠運用(yong)扳(ban)手(扳(ban)手長(chang)度(du)(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/
