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。
Water supply pipe as a part of the coal mining machine cooling system, need to cross the planetary head, the rocker shell waterway and roller spray system connectivity, so the water supply pipe is absolutely not leak, water pressure 10MPa, and due to Structure, the head of the water supply pipe and the body are welded together and, therefore, the need to design special tooling to test the water supply pipe to test the pressure resistance of the weld and the wall of the pipe to ensure that It’s working. A design scheme of water pressure test fixture is described.
