The common breakdown cause that causes abnormal knocking has 1, connecting rod tile wears away serious, connecting rod bolt becomes loose, connecting rod lining wears away serious, main shaft wears away serious or attaint produces clash; 2, leather belt loosens too or leather belt chamfer not agree with cause skid generation howl cries; 3, after pneumatics accident goes, did not begin to lubricate instantly, the metal does attrition to produce howl to cry; 4, secure used bolt to become loose, snail ages aperture produces knock sound greatly too; 5, the piston has a foreign body very.
2, judge breakdown
1, whether does tile of tile of examination connecting rod, connecting rod lining, main shaft wear away, be pulled or burn caustic, whether does connecting rod bolt become loose, examination pneumatics machine advocate oil duct is expedite; 2, check advocate, passive leather belt annulus groove consistent; 3, examination lube enters pipeline of oil pressure force, engine oil whether damaged, jam, those who check lubricating oil is oleaginous reach matter content, whether does examination pneumatics machine offer oil; 4, whether does fixed bolt shake examination pneumatics machine, examination gear has deny become loose or gear installation coordinates a case; 5, whether does the examination have other foreign matter.
3, trouble removal
1, change wear away serious or the plain bearing liner that pulls, lining, main shaft is made of baked clay, screw connecting rod bolt, with compress empty oily aperture to aim pneumatics machine inlet port; Gas dredge advocate oil duct. When be being assembled afresh, should notice main shaft bearing; 2, change abhorrent leather belt, adjust leather belt degree of tightness to spend; 3, inadequacy of the pressure that receive oil should be adjusted instantly, clear, change invalidation pipeline, if lube impurity exceeds mark to should change instantly, if pneumatics machine is not had,should have comprehensive examination instantly for oil; 4, the screw that close solid shakes, the gear that cooperates to have a problem gives change; 5, cleared eyewinker.
