1、锅炉水泵发出噪音通常是水流发出噪声和水泵自身结构产生的噪音。水流发出的噪音是在泵系统中由整倍转速下的周期性脉动,由泵内高流速下产生的紊流或者由汽蚀所产生;结构产生的噪声是由泵内的机械振动或泵和管路内液体脉动所引起的振动造成的。
Boiler water pump noises are usually noisy and pump noise generated by its structure. Flow noise emitted by the pump system in the periodic speed pulsation under aneuploidy, by the turbulence generated by the pump or a high flow rate is generated by cavitation; structural noise generated by the mechanical vibration of the pump or pump and vibration caused by the pulsation in the liquid line caused.
2、炉鼓风机的噪声主要是来自风扇引起的空气震动性噪音、转子与定子间的摩擦噪声和机体运转振动造成的噪音。鼓风机风扇叶片处加套消声器,把整个电动机半围封起来,阻挡了了外壳向外传播噪音的道路,于大功率的鼓风机,可安装全装式隔音罩,将整个鼓风机罩在里面,在罩子上打进出气口,然后上消音器。
Furnace blower noise mainly from friction noise and airframe noise operation between rotor and stator vibration caused by the vibration of air caused by fan noise. Blower fan blades at jacketed muffler, the whole semi-enclosed motor up, blocking the path of the shell to spread noise, high power blower can be installed full-mounted enclosures, the entire blower cover on the inside, in the hood on scored outlet, then the muffler.
3、排气时,高温高压汽体向大气喷射时产生射流噪声.这种噪声可采用小孔喷注型消声器,将消声器安装于放空管口,选用排气消声器应注意消声器的排气力、流量温度遵循放空蒸汽的要求,保持有一定强度和耐腐蚀性,在高寒地区使用还应注意蒸汽结冰堵塞小孔而出现过压放空的危险,为此要采取必要安全措施。
When the exhaust, high temperature high pressure vapor into the atmosphere when a jet noise. This noise can be hole injection type muffler, the muffler installed in the vent pipe opening, the choice should be noted that the exhaust muffler exhaust muffler force, the flow follow venting steam temperature requirements, maintaining a certain strength and corrosion resistance, use should also be noted in the alpine region of steam and ice clogged pores appeared dangerous pressure venting, for which you want to take the necessary safety measures.
