WOODWARD調(diào)速器的裝置
為了使調(diào)速器能穩(wěn)定調(diào)節(jié)，在調(diào)速器中還要加入-一個(gè)裝置,其作用是在伺服活塞移動(dòng)的同時(shí)對(duì)滑閥產(chǎn)生-一個(gè)反作用， 使其向平衡的位置方向移動(dòng)，減少柴油機(jī)轉(zhuǎn)速波動(dòng)的可能性。這種裝置稱為反饋機(jī)構(gòu)。
液壓調(diào)速器在感應(yīng)元件和油量調(diào)節(jié)機(jī)構(gòu)之間加入-一個(gè)液壓放大元件(液壓伺服器)，使感應(yīng)元件的輸出信號(hào)通過放大元件再傳到油量調(diào)節(jié)機(jī)構(gòu)上去,因此也叫間接作用式調(diào)速器。
WOODWARD調(diào)速器運(yùn)轉(zhuǎn)式
調(diào)速器用于減小某些機(jī)器非周期性速度波動(dòng)的自動(dòng)調(diào)節(jié)裝置。全程調(diào)速器的基本結(jié)構(gòu)可使機(jī)器轉(zhuǎn)速保持定值或接近設(shè)定值。水輪機(jī)、汽輪機(jī)、燃?xì)廨啓C(jī)和內(nèi)燃機(jī)等與電動(dòng)機(jī)不同,其輸出的力矩不能自動(dòng)適應(yīng)本身的載荷變化，因而當(dāng)載荷變動(dòng)時(shí)，由它們驅(qū)動(dòng)的機(jī)組就會(huì)失去穩(wěn)定性。這類機(jī)組必須設(shè)置調(diào)速器，使其能隨著載荷等條件變化，隨時(shí)建立載荷與能源供給量之間的適應(yīng)關(guān)系，以保證機(jī)組作正常運(yùn)轉(zhuǎn)。調(diào)速器的理論和設(shè)計(jì)問題，是機(jī)械動(dòng)

WOODWARD governor device
In order to make the governor can be stably adjusted, a device is added to the governor, which acts on the slide valve while the servo piston moves, and a reaction is generated to make it move in the direction of the balanced position, reducing the possibility of diesel speed fluctuations. This device is called a feedback mechanism.
The hydraulic governor adds a hydraulic amplifier element (hydraulic server) between the induction element and the oil quantity regulating mechanism, so that the output signal of the induction element is transmitted to the oil quantity regulating mechanism through the amplifier element, so it is also called the indirect acting governor.
WOODWARD governor operating type
An automatic regulator used to reduce aperiodic speed fluctuations in certain machines. The basic structure of the full speed governor can keep the machine speed at a fixed value or close to the set value. Hydraulic turbines, steam turbines, gas turbines and internal combustion engines are different from electric motors, and their output torque cannot automatically adapt to their own load changes, so when the load changes, the unit driven by them will lose stability. This type of unit must be set up a governor, so that it can change with the load and other conditions, at any time to establish the adaptive relationship between the load and energy supply, to ensure the normal operation of the unit. The theory and design of the governor is mechanical
The research content of mechanics. There are many kinds of governors. Among them, mechanical centrifugal governor is widely used. The speed governor with tachometer generator or other electronic devices as sensors has been widely used in various industrial sectors.
