怎樣降低氣體增壓泵的噪音？
第一 氣體增壓泵設計之初At the beginning of the first gas booster pump design為了降低泵的噪聲，在泵的設計過程中，我們就注意葉輪葉片數與導葉葉片數的匹配，應互為質數避免共振。In order to reduce the noise of the pump, the pump design process, we will pay attention to the impeller blade number and the number of guide under plate matching, should avoid resonance are prime Numbers.以及葉輪和導葉、蝸殼徑向的合理間隙，這幾個因素控制不當也會成為噪聲源。And impeller and guide vane and diffuser radial clearance, improper control of these factors will also be a noise source.從水泵泵體結構上和水力設計上去減少噪聲源，這就保證先天性控制聲源的優越性。From the pump pump body structure and hydraulic design to reduce noise, this ensures the superiority of congenital control source.第二 氣體增壓泵在使用中的噪聲控制方法The second gas booster pump noise control methods in use1 水泵安裝和操作的合理性1 the rationality of the water pump installation and operation安裝時應嚴格執行安裝程序，以防產生噪音。When installation should strictly carry out the installation program, to prevent noise.在操作上要注意排氣(排空)，保證允許的吸上高度或保證必需的汽蝕余量NPSHr，控制泵的最小流量，和管道離心泵的超負荷流量運行。Attention should be paid to exhaust (empty) on operation, ensure that allowed on the suction height or to ensure that the necessary NPSH NPSHr, control the minimum flow of the pump, and overload flow operation of the pipeline centrifugal pump.2 采取防護措施防止噪音2 take protective measures to prevent the noise在氣體增壓泵http://www.rizhaowx.com/ 安裝過程中，在管架的支承部位放置可以起防振作用的墊片，如橡膠墊及棉織物，加大基礎的設計并設置隔離墻。In the process of gas booster pump installation, placed in the bearing parts of the pipe rack vibration can prevent the gaskets, such as rubber mat and cotton fabrics, basic design and set up the wall.另外，可以在泵、電機周圍設置隔音罩或者增加隔音棉。隔音罩可采取隔音性能好的材料制造，這種方法比較容易辦到，收效快。In addition, you can set up around the pump and motor enclosures or increase the sound insulation cotton. Enclosures may take good sound insulation performance materials, this method is easier to manage, has achieved fast.國外、國內均采用此辦法來解決噪聲超標準機組的噪音問題。Domestic and abroad, adopts the way to solve the problem of noise for excess noise of the unit.3 無脈動消聲器3 no pulse muffler無脈動消聲器，有膨脹形和相位互擾形兩種類型，外制成了雙層筒形為這種無脈動消聲器的外形。No-pulsation muffler, expansion and phase entangled two types of external made double cylinder for the appearance of this kind of no-pulsation muffler.將這種無脈動消聲器安裝在裝置后，收到了較明顯的效果。Will be installed on the device, this kind of no-pulsation muffler received obvious effect.泵壓力脈劫產生的頻率噪聲由于安裝了無脈動消聲器，這種頻率的噪聲幾乎完全衰減了。Pump pressure pulse of the frequency of the noise is due to installation without pulsation muffler, the frequency of the noise attenuation almost completely.
