Agricultural machinery maintenance do not miss fittings
When the agricultural machinery is maintained, it sometimes happens that due to the cumbersome work, the carelessness caused by the replacement and replacement of parts and components is missed, so that the phenomenon of failure of the locomotive is not uncommon. Here are a few examples. We hope that the pilots and repairmen pay special attention to repairing the agricultural machinery. 1ã€Replacement screw plug of centrifugal purification chamber A newly repaired S195 diesel engine burns continuously. After dismantling inspection, the reason is that when the assembly is installed, the screw plug of the crankshaft centrifugal cleaning chamber is missed, so that the oil leaks out, resulting in burning of the tiles due to poor lubrication. 2. Missing injector steel ball After a small diesel engine was replaced with a new nozzle, the atomization was poor. Remove the nozzle inspection and found that when the hand replaces the needle valve pair, it misses the steel ball at the lower end of the plunger. Therefore, when the regulator screw is screwed to the end, it can not make the injection pressure reach the normal requirement and cause poor atomization. 3, missing plug sleeve screw gasket After a repaired S195 diesel engine, the engine's speed fluctuates. Disassemble the oil pump and found that when installing the oil pump, the gasket on the plunger sleeve locating screw was missed, so that the positioning screw was screwed too deep and the plunger sleeve was tilted obliquely, causing the movement of the plunger and the adjusting rack bar to be hindered. Misaligned, resulting in high and low engine speed. 4, missing gear wheel wire ring There is an abnormal sound in the gearbox of a walking tractor. The inspection revealed that the auxiliary shift fork has been severely worn. It turned out that the main shaft gear was loaded with a steel wire retaining ring. During operation, the main shaft gear moved to the left and collided with the auxiliary shift fork and caused an abnormal sound. 5. Missing piston pin retaining ring After replacing the piston with a small four-wheel tractor, the steel sleeve was broken after running for a short time. Upon inspection, it was the pilot who had installed the piston pin snap ring when assembling the piston connecting rod. When the engine is working, the piston pin pops out and the liner is broken.
