If you take the blue smoke of the engine when accelerating at work, Shanghai second-hand excavator trading network, suddenly encountered the load increases, the engine throttle increased, the engine smoke a lot of blue smoke, Shanghai second-hand excavator price, can be a preliminary judge for engine the cylinder, the piston and cylinder seal gap is too large due to. This phenomenon is due to the engine throttle in the operation, after the oil sump, through 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, Shanghai second-hand excavator market, or because of piston ring counterparts of the reasons which led the channeling problem. How old digging machine used in accordance with procedures to adjust the tension of the track: (1) loosen the track: with a long socket wrench slowly counterclockwise rotary valve 1. To loosen track, in accordance with a long socket wrench counterclockwise slowly rotated directional valve (1), grease from the grease outlet. 2, turn on the valve (1) lap to lap and a half, it would be sufficient to loosen track. 3. If the grease can not be discharged smoothly, Shanghai second-hand excavator, can the track off the ground, and slowly rotating track. 4. After obtaining the proper track tension degrees in a clockwise direction the valve (1) and tighten to 147 cattle × m (15kgf × m). Note: Do not fast or excessive release valve, otherwise, the grease in the regulation of the hydraulic cylinders will emit. Care should be taken to put the valve (1) is released and can not be against the valve body or face Shanghai second-hand excavator price | Kim Ho used excavators | used excavators Shanghai by Shanghai Used Construction Machinery Co., Ltd.
