Used construction machinery excavator in the measurement of the cylinder gap, Shanghai second-hand excavator recovered the sale, failed to measure the direction perpendicular to the piston skirt piston pin hole, Shanghai second-hand excavator market, measured in the other direction. The structural characteristics of the aluminum alloy of the piston is small great as a cone, and the skirt portion is oval cross section, so that the gap in the circumferential direction of the cylinder is not equal. When measuring provisions to the long axis of the ellipse gap prevail, ie measuring clearance between the piston skirt perpendicular to the direction of the piston pin hole. This measure is more convenient, accurate, and in reciprocation, Shanghai second-hand excavator recovered the piston skirt due to lateral pressure in the direction perpendicular to the piston pin hole worn in a larger role. If you take the blue smoke of the engine when accelerating at work, suddenly encountered the load increases, the engine throttle increased, the engine smoke a lot of blue smoke, may be a preliminary judge for the engine cylinder, piston and cylinder seal gap is too large a. This phenomenon is due to the engine throttle in the operation, after the oil sump, Shanghai used excavators, by a large gap between the cylinder and the piston or piston rings, fleeing into the cylinder and participate in the combustion, a large amount of blue smoke. This situation requires the dismantling of the engine, and then determine specifically the oil as the piston and the cylinder gap is too big reason, or due to piston ring counterparts of the reasons which led the channeling problem.
