The utility model is of light quality, and the spray rod (12) will not be deformed because of its own weight; a plastic anti return oil pipe (3) is set on the injection rod, and the oil flow can be buffered when oil collection is collected, and the oil return problem is solved; the oil bottle (2) has a small outlet of the oil bottle, and the oil flow is conveniently put into the oil pipe, and the oil flow is directly collected after the bottle mouth is out. The oil pipe is inflow to solve the oil leakage problem at the joint.
【技术实现步骤摘要】
复杂管腔类零件的简易收油装置
本技术属于流量试验领域,可用于所有复杂管腔零件(加力燃油总管)的流量试验,在流量试验中起收油作用。
技术介绍
发动机上的加力燃油总管(如图1所示,包括进油接头11;喷杆12;喷油孔13;焊接块14)进行流量试验时由于零件结构复杂,喷杆12排列紧凑,喷杆12上喷油孔13数量多,有的喷油孔13还靠近总管根部,焊接块14使喷杆12外形不规则,且试验压力大,油流流量大,导致收油难度大,普通塑料管无法套进喷杆12完成收油,进行试验时必须使用收油夹具才能完全收油。然而该总管作为新机试制零件,没有专用收油夹具,为了顺利完成试制,必须寻找其他方法解决试验收油难题。
技术实现思路
本技术要解决的技术问题是:提供一种用于复杂管腔类零件的简易收油装置,完成上加力燃油总管的收油工作。本技术的技术方案如下:复杂管腔类零件的简易收油装置,包括收油管,收油瓶和防返油管;所述收油瓶悬挂在喷杆上,包括一储油腔体和一出油瓶口;所述收油管与收油瓶的出油瓶口相连;所述防返油管置于收油瓶内,且套在喷杆外侧,防返油管上开有与喷杆上喷油孔错位的出油口。所述收油管和防返油管为塑料管,所述收油瓶为塑料瓶。所述收油瓶通过位于侧壁上且近收油瓶底部的开口悬挂于喷杆上,即套有防返油管的喷杆穿过收油瓶上的开口,使得收油瓶挂在喷杆上,这样收油瓶在油和自重的作用下有一倾斜角度。所述收油瓶的出油瓶口指向总管中心。所述防返油管的长度大于喷杆上喷油孔之间的最大间距。与现有技术相比,本技术的优点如下:第一、整套收油装置采用塑料材质,质量轻,不会因为自重原因将喷杆坠变形;第二、在喷杆上套一段塑料材质的防 ...
