柴油机的调速
Diesel engine speed
一、柴油机调速
One, the diesel engine speed con trol
柴油机的不同转速是通过改变循环供油量来实现的。
Diesel engine speed by cha nging differe nt fuel cycle to achieve.
改变柴油机的油量调节机构，使其转速调节到规定的转速范围内就称柴油机调速。
Change engine oil amount regulating mechanism, the speed regulation to the specified speed range is called the gover nor for diesel engine.
为了实现柴油机调速，就必须设置专门的调速装置，以便根据柴油机负荷的变化自动调节供油量，维持 其规定的转速范围。这种装置称调速器。
In order to realize diesel engine speed, we must set up a special speed regulat ing device, accord ing to the diesel engine load changes automatically regulates the oil supply quantity, maintain its specified speed ran ge. Such a device called the gover nor.
二、调速器的类型
In two, gover nor type
n按调速范围分类
Accord ing to the classificati on of N speed range
n按执行机构分类
N actuator accord ing to classificati on
1、按调速范围分类
In 1, according to the speed range classification
极限调速器（限速器）一一只用于限制柴油机的最高转速不超过某规定值，在转速低于此规定值时不 起调节作用。此种调速器仅用于船舶主机，目前已很少单独使用。
limit governor ( governor) -- only to limit the maximum speed of diesel engine does not exceed a
②单制式调速器（定速调速器） 用于发电柴油机。
specified value, the rotational speed is lower than the prescribed value does not play a regulating role. The gover nor is used only for mari ne engine, now rarely used alone.
在负荷变化时，能使柴油机转速保持在规定范围内。此种调速器应
The sin gle system gover nor ( con
