Shandong generator set valve clearance adjustment and measurement?
Shandong Huaquan Power Co., Ltd. (abbreviation: Huaquan Power) is located in Weifang Economic and Technological Development Zone, specializing in the manufacture of diesel generator sets, gasoline generator sets, natural gas generator sets, and diesel engine accessories. Generator set products, energy-saving and durable, are the first choice for standby (emergency) power supply in industrial and agricultural production, engineering construction, public service and other fields.
Shandong generator set valve clearance adjustment and measurement?
Shandong generator set valve clearance how to adjust and measure? The excessive air gap between the generator units in Shandong caused insufficient gas filling and insufficient exhaust. If the valve clearance is too small, the valve will close and the high temperature gas will leak out of the gap and burn the valve. Therefore, if the valve is too large or too small, the power of the diesel engine will be reduced and the economic performance will be reduced. During the use of the diesel engine, the valve clearance must be checked and adjusted regularly. The method is as follows:
1, first remove the valve cover, and then shake the crankshaft, so that the piston in the top dead center of the compression stroke (flywheel "top dead center" alignment with the tank alignment line), close the decompression device. Insert the gauge between the rocker head and the valve rod end and measure the clearance.
2. It is worth noting that the valve clearance at hot and cold vehicles needs to be measured and the measured values ​​compared with the technical specifications. The intake valve clearance is 0.35 mm and the exhaust valve clearance is 0.4 mm.
3, hot car intake valve clearance is 0.25 mm, exhaust valve clearance is 0.3 mm, if not meet the specified value, then adjust.
4. When the diesel generator set adjusts the valve clearance, loosen the lock nut first and use the screwdriver to adjust the adjustment bolt until the clearance is suitable. Then use a screwdriver to adjust the bolt, tighten the lock nut. Then check whether the gap fits.
5, but in the valve rocker head with dimples, adjust the valve clearance, it is best to adjust the valve in a prescribed order to no gap so far, according to the valve adjustment screw pitch and the required valve clearance back to adjust the corresponding screw about Number of gaps. This method is more accurate than using thickness rules. For multi-cylinder diesel engines, adjustments are made in order according to the work sequence and valve arrangement.
