【正文】 TRUCTIONS● 安裝Assembly1 檢查油口及連接螺紋，保證無臟物、毛刺及其他異物。Inspect port and connectors to ensure that threads on both are free of dirt,burrs and excessive nicks.2 在外螺紋上加密封料。但在第2 牙螺紋上不要覆蓋密封料，以免污染系統(tǒng)油液。加生料帶時應(yīng)按順時針方向（從管端看） 圈到2 圈。Apply sealant to male pipe any sealant,the first one or two threads should be left uncovered to avoid system Teflon tape is used it should be wrapped thread end.3 用手?jǐn)Q緊， 到3 圈， 圈左右，大規(guī)格扳緊2 圈左右。First tighten the fitting with hand,then with a wrench ,the small fiiting is tighten about turn andthe large fitting is tighten about 2 turns.● 重復(fù)安裝Reassembly錐管螺紋接頭可以重復(fù)安裝，重復(fù)安裝時應(yīng)檢查密封料是否已損耗，需要時將接頭清理干凈后重新加密封料安裝。The taper thread fitting can be reassembled,check if sealant has worn thin.● 泄漏原因Leakage reason1 沒有使用密封料或密封料已損耗。There is no sealant used or sealant has worn thin.2 螺紋已磨損。Threads are galled.3 螺紋制造不正確，接頭螺紋已進(jìn)入油口很深但仍未旋緊。Fitting screws in too far into the port.4 螺紋有嚴(yán)重缺口或刻痕。Threads are severely nicked.5 因振動導(dǎo)致螺紋松動。Threads are loosen. 硬管管路的正確布置 Routing of Tube Lines安裝布置硬管管路時，應(yīng)注意下列幾點：Routing of lines should have the follwing characteristics:● 管子長度要短，管徑要合適，流速過高會損失能量● The length of tube should be short and tube . should be suitable.● 兩固定點之間的連接，應(yīng)避免緊拉，需有一個松彎部分，如圖1 所示，以便于裝卸，也不會因熱脹冷縮而造成嚴(yán)重的拉應(yīng)力?！?The tube is in long lines to allow for expansion and contraction,as shown in Fig. 1. ● 管子的彎管半徑應(yīng)盡可能大， 倍。管端處應(yīng)留出直管部分，其距離為管接頭螺母高度的二倍以上。如圖2 所示。● The tube bending radius is large as min. bending radius is about of the tube ..The tube end should be straight and the spacing is above 2 of the tube Fig. 2: ● 硬管的主要失效型式為機(jī)械振動引起的疲勞失效，因此當(dāng)管路較長時，需加管夾支撐， 不僅可以緩沖振動，還可減少噪音。在有彎管的管路中，在彎管的二端直管段處要加支撐管夾固定，在與軟管連接時，應(yīng)在硬管端加管夾支撐。管夾間距推薦如圖3 及表1。Fatigue failure due to mechanical vibration accounts for the majority of tube line the tube line is longer,we can use tube clamps to support the clamping of the tube can reduce system tube clamp spacing as shown in Fig. 1 and table 1:● 避開障礙物時不要使用太多的90176。彎曲管，流體經(jīng)過一個90176。的彎曲管的壓降比經(jīng)過兩個45176。的彎曲管還大。如圖４應(yīng)選用正確的彎管角度?！?Get around obstructions without using excessive amount of 90176。 drop due to one 90176。 bend is greater than that due to two 45176。 Fig. 4: ● 布置管路時，盡量使管路遠(yuǎn)離需經(jīng)常維修的部件。如圖5 所示。● Keep tube lines away from ponents that require regular maintenance. ● 管路排列應(yīng)有序、整齊，便于查找故障、保養(yǎng)和維修。如圖6 所示?！?Have a neat appearance and allow for easy troubleshooting,maintenance and Fig. 6: 注：本資料摘自PARKER CATALOGUE 4300 SEPTRMBER 2000 A38 頁及《新編液壓工程手冊》下冊P。 螺紋扭矩建議表 Remended Thread Torque 公制O 形圈平面密封扭矩、74176。公制扭矩 密封件 Seal 單位轉(zhuǎn)換表CONVERSION FACTORCopyright 上海取成流體設(shè)備有限公司.
