鋼波紋管先從軸向(xiang)用(yong)(yong)M4螺(luo)釘固(gu)定在(zai)定位(wei)環上,再用(yong)(yong)m螺(luo)釘從直徑方向(xiang)將定位(wei)環固(gu)定在(zai)軸套上,這樣就存(cun)在(zai)累計誤差,不(bu)易確(que)保鋼(gang)波紋管端面垂(chui)直于(yu)軸套。壓蓋上沖刷油和冷卻水注(zhu)入孔位(wei)置不(bu)合理,冷卻水的通徑有一半孔被靜環密(mi)封圈擋住。
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(xing)成(cheng)靜環(huan)冷卻水減(jian)少,密(mi)封面冷卻效(xiao)果不好(hao);沖刷油孔離動、靜環(huan)密(mi)封面太(tai)遠(軸向間隔太(tai)長),使沖刷油不易注入(ru)到鋼波(bo)紋管密(mi)封處。直徑偏小鋼波(bo)紋管內徑62mm,密(mi)封比壓偏大;軸徑為55mm,軸套(tao)外徑為60mm,壁厚(hou)僅為2.5mm,壁厚(hou)偏小,簡單變形(xing),形(xing)成(cheng)拆、裝困(kun)難(nan)。
用(yong)(yong)戶(hu)柜子(zi)(zi)中心(xin)的孔(kong)的直徑≥2.5cm,由于金屬(shu)管(guan)兩側的接頭(tou)比(bi)中心(xin)軟管(guan)厚,而且用(yong)(yong)戶(hu)柜子(zi)(zi)的一些(xie)眼睛僅夠假如裝置要求(qiu)用(yong)(yong)戶(hu)事前打(da)孔(kong)或(huo)重新打(da)孔(kong)以方便波紋管(guan)穿過(guo)則軟管(guan)要經過(guo)。一些(xie)用(yong)(yong)戶(hu)原來的天然(ran)氣界面十分接近大理石臺面。
金屬管界(jie)面需(xu)要(yao)具有程度的曲率,較小(xiao)曲折面積≥30mm。假如(ru)曲率小(xiao)于(yu)上述(shu)大小(xiao),則無法暫時裝置。該界(jie)面位(wei)于(yu)用戶家的一角,而(er)且被(bei)單(dan)獨(du)阻止(zhi)。存在潛在的安全隱(yin)患,需(xu)要(yao)在裝置前進行糾正。請檢查(cha)接頭是(shi)否別(bie)離(li)卡住以及是(shi)否能夠運用扳手(扳手長度為(wei)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/
