Speed governor, also known as speed controller or speed regulator, is an automatic adjustment device mainly used to control and regulate the speed of engines, electric motors, or other rotating mechanical equipment. It perceives the actual speed of the rotating equipment, compares it with the preset speed target value, and automatically adjusts the power input (such as fuel supply, current size, etc.) to keep the speed of the rotating equipment within the set range.

SPM-D11 also known as:
Speed governor SPM-D11
SPM-D11 Control motherboard card speed controller
Speed turbine control unit SPM-D11
SPM-D11 Speed control controller
Digital expansion module SPM-D11
SPM-D11 speed governor is an automatic adjustment device specifically designed for controlling and adjusting engine speed. It is widely used in fields such as ship power and industrial machinery to ensure that the engine can operate stably within the preset speed range when the load changes.
Working principle of SPM-D11 speed governor:
The relationship between load and speed:
Changing the amount of fuel can change the load of a diesel engine while keeping the engine speed constant. On the contrary, if the load of the diesel engine is kept constant and the amount of fuel is changed, the speed of the diesel engine can be changed.
The function of the sensing element:
The governor contains sensing components (such as flying balls, centrifugal blocks, etc.) inside, which can sense changes in engine speed. When the speed changes, the sensing element will generate corresponding centrifugal force or displacement.
Adjustment process:
When the engine load decreases, the speed will naturally increase. At this point, the centrifugal force generated by the sensing element (such as the flying ball) increases, pushing the speed bar or similar transmission mechanism to move to the right.
This movement will trigger the control logic of the governor, transmitting pressure oil or mechanical force to the fuel supply adjustment mechanism of the fuel injection pump through a hydraulic servo mechanism (if it is a hydraulic governor) or other mechanical transmission mechanisms.
In the hydraulic governor, pressure oil enters the right space of the servo cylinder, and at the same time, the oil in the left space is discharged into the low-pressure oil circuit. Under the action of pressure difference, the servo piston will drive the rack of the fuel injection pump to move to the left, thereby reducing the fuel supply.
When the fuel supply decreases, the engine speed will gradually drop back to the set value. At this point, the centrifugal force generated by the sensing element decreases, the speed rod or transmission mechanism returns to its original position, the servo piston also stops moving, and the adjustment process ends.
Feedback mechanism:
Some speed controllers also include feedback mechanisms (such as rigid feedback mechanisms or elastic feedback mechanisms), which can further improve the accuracy and stability of speed regulation. Through a feedback mechanism, the governor can monitor the engine speed and load changes in real time, and adjust the fuel supply accordingly.
The functional characteristics of the SPM-D11 speed governor:
Accurate speed control:
High precision adjustment:
The SPM-D11 speed governor has high-precision speed regulation capability, which can automatically adjust the fuel supply according to changes in engine load, ensuring stable operation of the engine within the set speed range.
Quick response:
Through advanced sensing components and fast response control algorithms, the SPM-D11 speed governor can quickly sense changes in speed and make corresponding adjustments to reduce speed fluctuations.
Stability performance:
Automatic matching function:
As part of the SPM-D11 series load sharing synchronizer module, SPM-D11 has the function of automatically matching frequency, phase, and voltage levels, which helps to improve the overall stability of the generator system.
Protection mechanism:
The SPM-D11 speed governor is designed with a comprehensive protection mechanism, which can take timely measures to protect the engine from damage in abnormal situations. For example, providing on-site diagnosis and alarm indications through the LCD display interface helps operators detect and solve problems in a timely manner.
Intelligence and ease of use:
Intelligent control:
The SPM-D11 speed governor may have integrated microprocessor technology, making control more intelligent and flexible. Users can set and monitor parameters through the configuration interface or connect to a PC, improving the convenience of operation.
User friendly interface:
Equipped with two LCD display interfaces, providing operators with clear and intuitive information display and fault diagnosis prompts, reducing operational difficulty and maintenance costs.
Physical design and protection:
Standard size and weight:
This governor has standard physical dimensions (such as 144 mm x 72 mm x 122 mm) and an appropriate weight (at least 800 g), making it easy to install and integrate into various systems.
Protection level:
Designed with a protective casing, the front has an IP42 protection level and the back has an IP24 protection level, ensuring stable operation and safety in different environments.
Adaptability and Compatibility:
Wide applicability:
The SPM-D11 speed governor is suitable for various application scenarios, such as ship power, industrial machinery, etc., and can be integrated into systems with similar design components.
Compatibility:
As part of the three-phase AC system, this speed controller is compatible with speed control and voltage regulators, enhancing the overall performance and reliability of the system.
Reliability and Durability:
High quality materials:
Using high-quality materials and manufacturing processes to ensure the durability and long-term stability of the governor.
Comprehensive Protection Warranty:
Provide automatic and comprehensive protection warranty service, which takes effect immediately after purchase, providing additional protection for user use.
In summary, the SPM-D11 speed governor is a high-precision and highly reliable automatic adjustment device. It achieves efficient and stable engine operation and overall system performance improvement through real-time monitoring and adjustment of engine speed. It has broad application prospects in fields such as ship power and industrial machinery.
