Ua rau Analysis thiab daws ntawm Diesel Cav Flying

Qhov tshwm sim ntawm lub cav siv hluav taws xob ya yog qhov tshwm sim uas thaum lub sijhawm ua haujlwm ntawm lub tshuab hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem ntawm nruab nrab thiab me me load, qhov ceev ntawm lub cav diesel nce sharply rau qee qhov laj thawj, kev ua haujlwm overspeed tsis tuaj yeem tswj tau. cov pa roj tso pa tawm cov pa taws tuab, thiab lub suab thiab kev co yog qhov loj.

After the occurrence of "flying", with the increase of the speed of the diesel engine, the leakage between the plunger of the fuel injection pump and the plunger sleeve decreases, and the diesel oil entering the cylinder increases, causing the speed of the diesel engine to increase again, thus forming a vicious circle. The increasing speed of the diesel engine makes the temperature in the cylinder increase continuously, the expansion of the piston increases, the movement of each part of the piston connecting rod group intensifies, and the load increases. Severe accidents such as broken crankshafts and smashed pistons, cylinder liners and heads. Therefore, once the diesel engine "flying", measures must be taken to shorten the "flying" time and reduce losses.
