由于柴油机高压油泵柱塞偶件在使用过程中有磨损,使得工程机械在大修、中修甚至保养中都要对油泵进行修校,即校准标定油量、校正油量、起动油量和怠速油量。对于与一定用途的柴油机匹配好的油泵来说,这4个油量参数是固定不变的,这些油量参数之间有一定关联,且以标定油量最为重要。 目前,现场修校时油量参数的获得主要靠修校工的记忆或查资料,但常常不能满足要求,因而油量参数的确定往往成为修校工作中十分棘手的问题。现介绍一种行之有效的简易计算方法供参考。
As diesel engine high pressure pump plunger coupling wear in the course of use, making the construction machinery overhaul, repair or even in the maintenance of the pump to be calibrated, that is calibrated calibration of fuel, the amount of fuel, starting oil and idling oil the amount. For a certain purpose diesel matching pump, the four fuel parameters are fixed, the relationship between these fuel parameters, and to calibrate the amount of oil is most important. At present, the oil parameters are mainly obtained from the memory of school workers or check the data, but often can not meet the requirements. Therefore, the determination of fuel parameters often becomes a very difficult problem in the school. Now introduce an effective simple calculation method for reference.
