1. When the diesel generator set automatically stalls, the speed gradually decreases, the operation is unstable, and white smoke is emitted from the exhaust. This phenomenon indicates that there is water in the diesel, the cylinder seal is. washed, or the automatic pressure relief is damaged, etc. ?
Measures: Replace the cylinder seal and adjust the pressure reducing mechanism.
Other extinction phenomena and solutions:
1. During automatic shutdown, operation is continuously unstable and accompanied by abnormal knocking noises. This phenomenon is a sudden mechanical failure.
Common causes: broken crankshaft, broken piston pin, loose or broken connecting rod bolts, valve lock part, falling valve circlip, broken valve spring or broken valve stem, causing the valve to fall, etc.
Measures: Stop the machine immediately to inspectection in order to avoid major mechanical accidents. It can be sent to a professional maintenance point for multiple inspections.
2. When automatic shutdown, the speed suddenly decreases and black smoke is emitted from the exhaust pipe.
Reason. : The cooling system is insufficient, the engine overheats, causing tension and jamming of the piston in the cylinder liner, the friction pair is poorly lubricated, the shaft is burned or the valve train parts are seized, etc., causing the engine to be removed and stalled.
Measures: Strengthen the maintenance of the lubrication system and cooling system, and add sufficient lubricating oil and cooling water.
Extinction:
Also called extinction. When the reactor is operating at a significant reaction rate, if the feed inlet temperature is lowered so as to reach the limitte lower than the multiplet region, the reaction rate will suddenly drop significantly and the reaction will virtually stop. This phenomenon is called extinction. The corresponding inlet temperature is called the extinction point. Usually refers to the car stalling.
Gasoline generators often stall automatically during operation. There are several reasons. One is lack of oil, the other is the oil circuit blocked, the third is the body temperature is too high. and the fourth is The load is too great. These situations will cause the gasoline generator to automatically stall during operation.
If the machine is not very old or old, it is recommended to replace the spark plug and carburetor. If it is certain that the spark plug is not the fault, it is recommended that the oil supply line is not smooth and that it is notcleaned or replaced.
Detailed information:
How to store gasoline generators when not in use used for a long period of time:
1. Drain all gasoline in the fuel tank and carburetor;
2. Drain all the oil in the crankcase
3. The engine oil reaches the upper limit of the oil level on the oil dipstick;
4. Close the choke and pull the starter handle to where resistance is felt;
5. Clean the device, cover it with cardboard or a plastic cover to prevent dust.
