  沼气发电机机组体损坏的修复方法与并机原理:

  The biogas generator unit body damage repair methods and principle of weaver:

  1、冻裂。这是冬季柴油发电机容易发生的损坏。机体出现的裂纹只有在不受力的部位才可以用冷焊法修复。首先在裂纹两端打止裂孔,然后沿裂纹栽若干颗铁钉,再垂直于裂纹方向补板若干块,用低碳钢焊条沿裂纹和补板焊牢。注意边焊边用小锤轻敲焊缝,全部焊完后再用火焰矫正。

  1, the frost crack. This is winter diesel generator the most prone to damage. The body appear crack only without mechanical parts of the cold welding method can be used to repair. On both ends of the crack to play the check in first, and then planted some nails, along the crack perpendicular to the direction of crack filling several boards again, with low carbon steel electrode along cracks and filling plate welded. Pay attention to the edge, edge with a small hammer tapping welding with all correction after welding with a flame.

  2、上下平衡轴端205轴承孔磨损。这种情况必须马上修理。轴承孔磨损较轻时,可用加大205轴承外圆法修复,在轴承外圈用氧焊将钢丝对称点在个小点,用锉修正一下,然后压入轴承孔即可使用。另一种方法是用2毫米厚的铁板做一个内孔为50毫米的大平垫,在平垫和机体上做三个丝孔,用平头螺钉固定上去。当轴承孔磨损严重时,可以镗大原孔镶套,并在镶入的衬套和机体结合部做三个小丝孔,用螺钉固定。

  2, up and down balance shaft end 205 bearing hole wear. This situation must be repaired immediately. Bearing hole wear lighter, available increase 205 bearing outer circle method to repair, and the bearing outer ring with oxygen welding wire symmetry points in a small, use file to fix, then pressed into the bearing hole can be used. Another method is to use 2 mm thick plate to do a hole for 50 mm pad, the Pacific Ocean in three wire hole is done on flat pad and the body, with flat head screws up. When worn bearing hole, and assembling can be boring and the original hole and insert the bushing and the integration of a body to do three small orifice, with screws.

  3、缸头螺栓孔滑丝或破损。这种情况是由于拧紧缸头螺母时用力过大或捣缸造成。如果是个别丝孔滑丝,可重新改丝,并加工一个与该丝孔配套的缸头螺栓即可。如果丝孔破损或多个丝孔滑丝则不能修复。

  3, cylinder head bolt hole slide wire or damaged. This kind of situation is due to the tight cylinder head nuts when too much force or dao cylinder. If the individual wire hole slide wire, wire to change, and one with the silk hole form a complete set of cylinder head bolt. If the wire hole breakage or multiple orifice slide wire is not fixed.

  4、沙眼。先用钢丝锥扩孔,然后用铝丝塞住,或用点焊法堵住即可。

  4, trachoma. With steel tap hole first, then use aluminium wire plug, or blocked by spot welding method.
