Shanghai Dongfeng Pump Valve Factory produces three kinds of electric butterfly valves, namely JG electric butterfly valve, JGF electric butterfly valve square and JGF electric butterfly valve.
This series of products are made of metal and composite, and the surface is completely covered to prevent metal corrosion. The natural frequency under rated load is low, which is suitable for vibration isolation and noise reduction of the foundation of power machinery such as fans, water pumps, air compressors, refrigerators, etc. with a rotating speed of more than 600 rpm, especially for the foundation vibration isolation of vertical water pumps, with good equal frequency performance. When the load is greater than the rated load, the natural frequency of the vibration isolator remains unchanged, the damping ratio is large, the ability to suppress the resonance peak is strong, and the structure is simple It is easy to install. It can be directly installed under the engine base, and can also be fixed and installed with foundation bolts. It is safe and reliable to use. The load range is 150N-8500N. It is resistant to oil, sea water, salt, fog and sunshine, and is applicable to the temperature range of - 15~70 ℃.
JGF electric butterfly valve square JG vibration isolator is bonded by metal parts and body. The product is divided into four size structures and eight bearing specifications. The axial load is 10-1288Kg, the static deformation under rated load is 3-12mm, the corresponding natural frequency is 5-11Hz, and the damping ratio is 0.05.
Applicable equipment: water pump, fan, cooling tower, air compressor, air conditioning unit, diesel engine, water chiller, air energy equipment, etc
