Locomotive fuel must pass through the check valve in such aspects as unloading and transportation, adjustment and storage, and measurement and distribution. The fuel is corrosive and the new valve has begun to leak within less than six months. According to statistics, 1100 kilograms of fuel is lost in one segment each year, equivalent to nearly 4,000 yuan. Wang Yaobin and Chen Yanlin, the surveyors, began to ponder over the problem of leakage as early as two years ago. After many experiments, they found that the use of discarded air duct aprons as check valve packing material, the leakage effect is significant. With this method, more than 3,000 kilograms of fuel can be plugged into the segment each year.
How to control the chronic problems of the fuel valve packing leakage
Without spending a penny, the use of discarded duct aprons will cure the chronic problem of the fuel valve disc packing leakage. This is the result of the use of two quantifiers in the Harbin Locomotive Depot. This alone can save more than 10,000 yuan in cost per year.
