渭阳柴油机厂生产的12150L柴油机,是一种转速为2000转/分的高速柴油机,系军用车辆配套产品。要求精度高,马力大,机体紧凑。随着我国工业的发展,这种柴油机的各种变型产品,已在石油钻探、固定发电、船舶动力、矿山载重汽车和起重运输机械等方面得到了广泛的应用。这种柴油机对配气机构的要求相当严格。这是因为四冲程柴油机每换一次气,时间只有0.03秒,换气时间短与进气充分、排气干净之间形成了尖锐的矛盾;所以要求气门总成既能调整又有一定的扭矩。这样,在选配过程中,就遇到了气门总成出现部分粘结的问题,使总成造成一定数量的废品。这个问题已经存在多年,难以解决,直接影响着产品质量的提高。今年
The 12150L diesel engine produced by Weiyang Diesel Engine Factory is a kind of high-speed diesel engine with a rotational speed of 2000 r / min, which is an accessory product for military vehicles. Requirements of high precision, horsepower, compact body. With the development of our country’s industry, various variant products of this diesel engine have been widely used in oil drilling, fixed power generation, marine power, mining truck and hoisting and transporting machinery. This diesel engine on the valve body requirements are quite strict. This is because every time the four-stroke diesel engine, the gas is only 0.03 seconds, ventilation time is short and adequate intake, exhaust clean formed sharp conflicts between; so requires the valve assembly can adjust both torque. In this way, during the matching process, the valve assembly encountered partial bonding problems, the assembly into a certain amount of waste. This problem has existed for many years, it is difficult to solve, directly affect the improvement of product quality. this year
