1.不需要井架,直接用钻杆往地下冲击即可。2.压水机可利用废旧材料自作(见前文图)。选用直径105～135毫米的废缸套及与其配套的旧活塞较合适,密封用原来的活塞环或橡胶圈皆可。活塞中间的圆孔尽量加工大些,孔太小了,活塞下行时上水太慢。缸套上部需钻个直径30～50毫米装出水管的孔。橡皮活门较重要,需用厚5毫米以上的橡皮制作,剪开的圆缝 1. Does not require derrick, direct use of drill pipe to the ground impact can be. 2. Water press can make use of waste materials themselves (see previous figure). Select the diameter of 105 ~ 135 mm waste liner and its supporting the older piston more appropriate seal with the original piston ring or rubber ring Jieke. Pistons in the middle of the hole as large as possible processing, the hole is too small, the piston down the water too slow. The upper part of the liner needs to drill a hole with a diameter of 30 to 50 mm to discharge the water pipe. Eraser valve is more important, need more than 5 mm thick rubber, cut the round seam
