11 调速器的修理调速器是自动调节高压油泵供油量的装置。它能使柴油机在负荷变化的情况下保持稳定,使柴油机在一定转速下稳定运转。柴油机对调速器的要求是:保证柴油机在怠速时以最低稳定转速运转;限制柴油机最大转速;根据负荷的变化变更供油量。调速器按照它所能调节转速的范围和功能可分为: a、定速调速器,亦称为单制调速器,无论外界负荷如何变化,都能保证柴油机在规定的转速下稳定工作,这种调速器适用于发电柴油机装置中。另外一种是全程式调速器,又称变速调速器和全制式调速器,这种调速器能保证柴油机在不同转速和负荷下适当调节油量,使之能保证柴油机在规定范围内稳定运转; b、极限调速器。此类调速器又分为单极调速器
11 Governor Repair The governor is a device that automatically adjusts the fuel supply to the high-pressure pump. It can make the diesel engine keep stable under the condition of load change, make the diesel engine run stably under certain speed. Diesel governor requirements are: to ensure that the diesel engine at idle speed with the minimum steady speed; limit the maximum speed of diesel engine; change in fuel load according to changes in load. Speed governor in accordance with its ability to adjust the speed range and function can be divided into: a, speed governor, also known as single-speed governor, no matter how changes in external load, can ensure that the diesel engine is stable at the specified speed Working, this governor is suitable for powering diesel engine installations. The other is full range governor, also known as variable speed governor and full speed governor, this governor can ensure that the diesel engine at different speeds and loads properly adjust the amount of fuel, so that it can ensure that the diesel engine in the specified range Stable operation; b, limit governor. This type of governor is divided into unipolar governor
