What are the types of speed governors?

The types of speed governors: 1. According to the different component structures, speed governors can be divided into two major categories: mechanical hydraulic type and electrical hydraulic type; 2. According to the different system structures, speed governors can be divided into three types: auxiliary servomotor type, intermediate servomotor type, and regulator type. The mechanical hydraulic type speed governor is also called a mechanical governor or mechanical regulator, while the electrical hydraulic type can be further divided into analog electrical hydraulic type and digital electrical hydraulic type. The second-level hydraulic amplification output signal is fed back to the comparison element to form the control regulation law of the governor. In this system structure, the first-level hydraulic amplification servomotor is called an auxiliary servomotor, which is mostly found in mechanical type and analog electrical type governors. The intermediate servomotor type governor system adopts a step-by-step feedback form, where the first-level hydraulic amplification output signal is fed back to the comparison element to form the control regulation law of the governor. The second-level hydraulic amplification output signal is fed back to its own input end to form a mechanical hydraulic follow-up amplification system.
There are several types of automotive governors, and as someone who enjoys tinkering with engines, I remember them clearly. The most common is the mechanical governor, which uses linkages and springs to directly control throttle opening in older vehicles, preventing runaway RPM—such as automatic adjustment during uphill climbs. Then there's the vacuum governor, which operates using intake manifold vacuum signals and was popular on 1970s American muscle cars. Another type is the electronic governor, where a computer module receives sensor data to precisely control throttle position. Additionally, cruise control systems incorporate governor modules to maintain constant speed, making long-distance driving particularly effortless. These governors all require regular maintenance, such as cleaning oil residue to prevent sticking and ensuring responsive performance and safety. I think mechanical ones are simple but prone to wear, while electronic ones are smarter but rely on stability.
