【正文】 When the tube is extremely hard擴口式接頭FLARED TUBE FITTINGS 擴口式接頭概述FLARED TUBE FITTINGS INSTRUCTIONS● 擴口式管接頭采用圖8 的結(jié)構(gòu)型式，由三部分組成：接頭體、襯套、螺母。When the nut is not tightened enough3 管子外表刮傷或管子不圓。t mean wrong installation. The cutting ring shall be refitted once the nut is retightened.● 泄漏原因Leakage reason1 管子沒插到底。卡套不能前后滑動，但允許有輕微轉(zhuǎn)動。Insert the tube into fitting body until cutting ring seats firmly in the fitting and handtighten the nut.2 用扳手?jǐn)Q緊螺母，直至擰緊力矩急劇增大，再擰緊1/4 至1/2 圈即可。Lubricate the fitting body to be subsequently nut until a noticeable increase in force is nut by 1/2 of a turn beyond this point for final assembly. ● 重復(fù)安裝Reassembly所有的卡套接頭都可以多次重裝，但要保證零件無損壞且清潔?？ㄌ卓梢陨孕D(zhuǎn)，但不能軸向推移。Tighten nut until ferrule grips tube which is felt by a noticeable increase in torque (increase in force).5. 達到壓力點后，再將壓緊螺母擰緊1/2 圈。Set a nut and cutting ring on the tube. Make sure the cutting ring and the nut are facing the fitting.3 在預(yù)裝配接頭體螺紋和卡套上涂上潤滑油，把管子插入接頭體，（管子一定要插到底）用手旋緊螺母。Cut the tube at right angle and deburr inside and outside of tube end. Minimum straight length of tube from the starting point of tube bend to the tube end may be 3 times height of the nut.2 把螺母和卡套套在無縫鋼管上。管子端面要與軸線垂直，176。Bite type fitting consists of three parts: body, cutting ring and nut. When tightening nut, cutting ring is driven forward on the tube then bites the tube with the edge of cutting ring, this is how sealing is achieved and results in internal ridge inside the tube. See Fig7.The tube connection side of fitting is manufactured in accordance with standard: DIN 3861. In general, body and nuts39。通常情況接頭體和螺母表面鍍鋅處理。錐的W型柱端按DIN 3861 標(biāo)準(zhǔn)。見圖P1。The connected nut is loosen.卡套接頭BITE TYPE TUBE FITTINGS卡套接頭概述BITE TYPE TUBE FITTINGS INSTRUCTIONS卡套式管接頭由三部分組成：接頭體、卡套、螺母。The ORing material is not suit for working temperature.6 O 形圈硬度不夠。The flange is too large or too small that the Oring can39。The ORing is damaged.3 接頭密封面、接管或翻邊有凹坑或其他影響密封的缺陷。Because the sealing surfaces are flat and perpendicular to the assemple pull,the Oring may be distorted during assembly. The Oring should be inspected at each disassembly and replaced when necessary. ● 泄漏原因Leakage reason 1 O 形圈未正確的安放在O 形圈槽內(nèi)。The fitting body should be installed Oring firstly.2 按圖1 或圖2，將接管或鋼管翻邊壓住接頭體O 形圈，用手?jǐn)Q緊螺母，再用扭矩扳手按P 的扭矩建議表扳緊；如無扭矩扳手，可用普通扳手再擰緊1/4 到1/2 圈。As shown in Fig. 1,the tube end is cut squarely(within +/ 1degree) before the . and . of the tube.Remove all oil and shown in Fig. 2,the tube is flanged to 90176。對圖2 的基本結(jié)構(gòu)，在垂直鋸下后用專用設(shè)備將管端翻邊成90176。 1176。如未說明，一般按圖5 所示的JB 標(biāo)準(zhǔn)生產(chǎn)。 The Oring could not enter the hydraulic system when the pressure is negative.
