after the start of the inspection engine
Turn power key to turn a file in a clockwise or press the start button , the starter motor and the diesel engine flywheel starter gear that meshes starting gear , driven engine starts running . Each starter continuous working time must not exceed 15s.
(2) the best time to start successfully , such as making the second start, twice starting interval scissor pallet truck be greater than 1min, not yet in stationary diesel engines and starter before the start button , in order to avoid severe impact damage parts. When the engine starts running , you should immediately release the start button or electric keys, avoid to damage the gears.
3 When the engine can not be started several times in succession , the response to such diesel fuel system or starter checks , troubleshooting doing start.
Second, after the start of the inspection engine
1 after starting the engine should be at low speed , check the meter indication is normal, listen to any abnormal sound , and make the necessary adjustments.
(2) Check for oil spills, leaks , leak, leakage, if necessary, tighten or repair.
3 Diesel preheated to 50 ℃, the instrument is working properly before starting or after crane hydraulic pump and PTO shaft combined until the hydraulic oil temperature reaches above 30 ℃ , can the lifting operation .
Third, the diesel engine running
1 engine after starting , you should first low-speed operation for some time, so that the engine warm-up , after the instrument is working properly , that should stop the continued low-speed operation , enter the artificial state. Low speed diesel engine , oil pressure should not be less than 1000kpa. Special attention should be : diesel should run at low speed for a long time , because the engine crankshaft speed lower than the rated speed, the fuel injector atomization will deteriorate over time, will lead diesel engine does not operate properly ; Secondly , prolonged low-speed operation will the lubricant viscosity , oil pump oil pump running slow cause insufficient , leading to poor lubrication of the bearing parts of the bearing alloy occurs off the block and other accidents , and low speed diesel engine work is not stable, easy to produce shock loads .
(2) When the engine temperature rises above 50 ℃ , the diesel engine can perform normal operation . Normal working temperature is best controlled at 80-90 ℃. Oil pressure should be between 300-400kpa .
3 diesel engine operation is prohibited battery master switch is turned off , you can not have abnormal sound or noises .
