Which Governor is Used in an Electric Generator


1. The function of the governor of diesel generator set

The function of the governor is to adjust the fuel supply automatically with the change of the external load of the diesel engine within the required speed range of the diesel engine, so as to keep the diesel engine speed basically stable.



2. Type of governor

A. According to the different classification of governor regulating mechanism, it can be divided into four types: mechanical type, hydraulic type, pneumatic type and electronic type.

(1) mechanical governor

The sensing element of the mechanical governor is a flying block or a flying ball, which directly pushes the actuator. Simple structure, reliable work, widely used in medium and small power diesel engines.

(2) hydraulic speed governor

The pressure governor generally uses the flying block as an inductive element to push the piston to operate the hydraulic server. This governor has small induction elements and strong versatility. A few series of dimensions can be used to meet the requirements of tens to ten thousand horsepower diesel engines. It has good stability, high adjustment precision and large driving force, and is easy to realize automatic control of diesel engine. But the structure is complex, the craft request is high, suitable for the high power diesel engine.

(3) Pneumatic governor

The moving governor uses the diaphragm to induce the change of the vacuum of the inlet pipe, and then to promote the actuating mechanism. The governor has simple structure and high sensitivity at low speed, but the power is decreased due to the throttle valve installed in the intake pipe. Therefore, it is only suitable for low power diesel engines.

(4) electronic governor (Mainly used in electric generator engine)

The electronic governor converts the change of diesel engine speed into the change of electric quantity, and controls the actuator after sampling and amplifying. This governor can adjust the fuel supply before the speed of diesel engine changes obviously, and obtain high adjusting precision, and realize parallel operation without difference.

Diesel Generator Power Ratings: Standby vs Prime vs Continuous

Diesel generator sets are commonly used in a variety of sectors due to their dependable performance and high efficiency. They can be used for emergency power supply in the event of a power cut or used in places without connection to a power grid. When selecting a diesel generator for your home or business, you need to consider many factors, such as generator’s ratings. In this article, we’ll explain the three basic rating types - standby, prime, and continuous in diesel generators. ISO-8528-1:2018 defines basic generator set rating categories based on four operational categories: Emergency Standby Power (ESP), Prime Power (PRP), Continuous Power (COP) and Limited-Time Running Prime (LTP). Read on and learn the application of power ratings for engines used in generating sets. Standby Power Rating Standby Power(ESP) is used to supply emergency power when the external power supply is interrupted, such as power outages. Standby power rated generators can supply reliable electricity as t...

What Should You Pay Attention to in Routine Maintenance of Diesel Generator Sets

In modern society, the stability of power supply is directly related to the operation efficiency of enterprises and people's quality of life. Diesel generators have become an indispensable backup power supply or main power source in various industries due to their high efficiency, durability and reliability. However, to ensure the smooth operation and optimal performance of the generator sets, regular maintenance is essential. Here is what you need to pay attention to in the routine maintenance of diesel generators. Keep your generator clean It’s important to keep the generator’s exterior and the generator room clean. Regularly remove any dirt, dust, or debris that may accumulate to on the generator’s surface. This is not only for the sake of beauty, but also for the smooth operation of the unit. Cleaning the generator’s exterior, air intake vents, exhaust outlets and generator room can effectively reduce the risk of generator overheating. In addition, check if the connection bol...
