[导读]: 在液压体系中,无论是金属管接头,仍是软管接头,都存在简单发作走漏的疑问。关于卡套式管接头,大多因管道遭到较大的外力或冲击力,使卡套松动或管端面变形而形成走漏,此刻应查看卡套是不是失圆、刃口有无残缺、管端是不是无缺以及卡套螺母的压紧程度等,一起还要消除管道外力。  In the hydraulic system, whether it

在液压体系中,无论是金属管接头,仍是软管接头,都存在简单发作走漏的疑问。关于卡套式管接头,大多因管道遭到较大的外力或冲击力,使卡套松动或管端面变形而形成走漏,此刻应查看卡套是不是失圆、刃口有无残缺、管端是不是无缺以及卡套螺母的压紧程度等,一起还要消除管道外力。

  In the hydraulic system, whether it is metal pipe joint, or hose joint, there is a simple leakage problem. About the bayonet type pipe joint, mostly because the pipe is subjected to greater external force or impact force, so that the bayonet loose or pipe end deformation and the formation of leakage, at this moment should check whether the bayonet is round, whether the blade is incomplete, pipe end is not missing and the degree of compression of the bayonet nut, etc., together with the elimination of external force pipeline.

  关于扩口式管接头,大多因扩口过度,质量不合需求或屡次拆开,致使扩口变形或裂纹等形成走漏,此刻可将前端截去从头进行扩口。若是运用公母锥顶压进行密封,其走漏大多是因为两锥面有损伤,可用研磨砂对锥面进行研磨。

  As for flaring type pipe joints, most of them are disassembled due to excessive flaring, poor quality or repeated disassembly, resulting in flaring deformation or cracks and leakage. At this moment, the front end can be cut off for flaring from the beginning. If the use of male and female cone top pressure for sealing, the leakage is mostly because of the damage of the two cone surface, grinding sand can be used for grinding the cone surface.

  在一些用“о”形圈靠端面或外径密封的场合,其走漏缘由有以下几种:“о”形圈老化或变形而形成走漏;“о”形圈装置不到位,使两平面衔接时压不平或“о”形圈被切开形成走漏;“о”形圈未压实,弹性变形量缺乏而形成走漏;“о”形圈止口槽过深而形成走漏。

  In some cases where the "macau" shaped ring depends on the end face or the outside diameter seal, its leakage reason has the following several kinds: "macau" shaped ring aging or deformation and form leakage; The "cut" shaped ring device is not in place, so that the two planes are connected unevenly or the "cut" shaped ring is cut to form leakage; The shape circle is not compacted, the elastic deformation is insufficient to form leakage; Too deep a groove at the groove of the groove groove of the shape circle forms leakage.

  对此,需从头挑选外径一样和截面较粗的“о”形圈,也可将带有止口槽的密封平面进行切削或磨削加工,以减小止口槽深度,使“о”形圈有满足的弹性变形量(紧缩量通常应在0.35-0.65mm之间)。

  In this regard, it is necessary to select the "" shaped ring with the same outer diameter and thicker section from the top to the bottom, or cut or grind the sealing plane with the groove at the mouth to reduce the depth of the groove at the mouth, so that the" "shaped ring has a satisfying elastic deformation (usually the contraction should be between 0.35-0.65mm).

  关于选用耐油胶板、羊毛毡、软钢纸板、组合密封垫圈或密封胶的管接头处走漏,无论是何原料,首先应查看其密封件有无破损,变形、老化和粗糙度过大等状况,然后采纳相应的办法。

  On the selection of oil resistant plastic plate, wool felt, mild steel board, combination of sealing gasket or sealant pipe joint leakage, no matter what raw materials, should first check whether the sealing parts are damaged, deformation, aging and roughness is too large, and then adopt the corresponding measures.
