舰船用66-10空压机排气压力为40和20MPa,自由状态排气量200m~3/h,额定转速1330r/min,采用四级压缩、水冷、级差活塞上方绞接高压活塞的V型结构,由一台90kW的直流复压电机直接驱动.机组共同装在焊接的钢制底座上,底座下方布置着E-400型隔振器.作为高速往复式机械,它既是船内结构噪声的振源,又是空气噪声的主要噪声源.在试验室测量,隔振器下的振动加速度级达128
Ship with 66-10 air compressor exhaust pressure of 40 and 20MPa, free state displacement of 200m ~ 3 / h, rated speed 1330r / min, the use of four compression, water cooling, differential piston above the high pressure piston articulated V Type structure, which is directly driven by a 90kW DC re-energizing motor.The units are mounted together on a welded steel base with an E-400 isolator under the base.As a high-speed reciprocating machine, it is not only a structural noise inside the ship Of the vibration source, but also the main noise source of air noise measured in the laboratory, the vibration acceleration level up to 128
