The governor is equipped with a servo valve that receives input from a tachometer or other speed sensing device, allowing it to make precise adjustments to maintain the desired speed.
This governor is constructed from high-quality materials to ensure durability and long service life. The housing is made of cast iron, while the governor vanes and other moving parts are made of forged steel. The hydraulic system is filled with mineral oil, which is resistant to oxidation and provides excellent lubrication.
The 6RA7081-6DV62-0 is designed to operate in harsh environmental conditions, with a temperature range of -40 C to 80 C (-40 F to 176 F) and a maximum pressure of 150 bar (2175 psi). It is also sealed against dust and water, making it suitable for use in industrial settings with challenging environmental conditions.
The governor comes with a variety of mounting options, including flange, bracket, and yoke mounting. It is also equipped with adjustable stroke length and damping, allowing for fine-tuning of the governor's response to load changes. Additionally, the governor can be outfitted with a variety of optional accessories, such as a pressure relief valve, temperature sensor, and vibration sensor.
In summary, the Siemens 6RA7081-6DV62-0 is a rugged and reliable hydraulic governor designed for use in industrial applications. Its servo-controlled design allows for precise speed control, while its robust construction and sealing against environmental factors make it suitable for use in challenging conditions. With a variety of mounting options and optional accessories, this governor is a versatile solution for controlling the speed of large engines and generators.
