          如何降低鍋爐噪音?

          1、鍋爐水泵發出噪音通常是水流發出噪聲和水泵自身結構產生的噪音。水流發出的噪音是在泵系統中由整倍轉速下的周期性脈動,由泵內高流速下產生的紊流或者由汽蝕所產生;結構產生的噪聲是由泵內的機械振動或泵和管路內液體脈動所引起的振動造成的。
          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、爐鼓風機的噪聲主要是來自風扇引起的空氣震動性噪音、轉子與定子間的摩擦噪聲和機體運轉振動造成的噪音。鼓風機風扇葉片處加套消聲器,把整個電動機半圍封起來,阻擋了了外殼向外傳播噪音的道路,于大功率的鼓風機,可安裝全裝式隔音罩,將整個鼓風機罩在里面,在罩子上打進出氣口,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、排氣時,高溫高壓汽體向大氣噴射時產生射流噪聲.這種噪聲可采用小孔噴注型消聲器,將消聲器安裝于放空管口,選用排氣消聲器應注意消聲器的排氣力、流量溫度遵循放空蒸汽的要求,保持有一定強度和耐腐蝕性,在高寒地區使用還應注意蒸汽結冰堵塞小孔而出現過壓放空的危險,為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.
