摘　　要：供水管做为采煤机冷却系统中的一个零件,需要穿过行星头,将摇臂壳体水道与滚筒喷雾系统连通,所以供水管是绝对不可以泄漏的,需耐水压10 MPa,而由于结构的限定,供水管的头部与本体之间是焊接而连在一起的,因此,需要设计专用工装,对供水管进行试验,检验其焊缝的耐压强度及管壁的密闭性,确保其正常工作。阐述了一种供水管水压试验工装的设计方案。The water supply pipe as a part of the cooling system in the coal mining machine, need to pass through the planet head and connect the rocker shell＇s water system with the shearer drum water system , so the water supply pipe cannot leake, it should resist water pressure of 10 MPa, because of the structure,the head and the body of the water supply pipe is welded together. Therefore, need to design special frocks to test the compressive strength of weld and tightness of the pipe wall, to ensure that it works properly. Presents a design scheme of water supply pipe＇s hydraulic testing frocks.
