產(chǎn)品詳情
根據(jù)噪聲傳播方式的不同,我們一般會(huì)采取隔振、消聲器、隔聲等方式處理熱泵機(jī)組的噪聲。熱泵機(jī)組屬于低頻噪聲,低頻噪聲的特點(diǎn)就是衰減緩慢、聲波較長(zhǎng)、穿透能力強(qiáng)(其衍射波能輕易繞過(guò)障礙物),所以低頻噪聲不易處理。從熱泵的結(jié)構(gòu)分析,噪聲源是壓縮機(jī)和排風(fēng)扇。壓縮機(jī)和排風(fēng)扇運(yùn)行產(chǎn)生噪聲,而且由于設(shè)備運(yùn)轉(zhuǎn)導(dǎo)致熱泵的鋼結(jié)構(gòu)產(chǎn)生微振動(dòng)和結(jié)構(gòu)振動(dòng)噪聲,但前者是主要噪聲。大型熱泵的實(shí)測(cè)噪聲級(jí)與銷(xiāo)售商提供的噪聲指標(biāo)或樣本上標(biāo)明的噪聲級(jí)有一定的差別,實(shí)測(cè)的噪聲都要超出3~1dB。

原裝FLUID-TEAM電磁閥 EEPDRDS3-05-75-4-24V技術(shù)參數(shù)
暗桿閘閥:閥桿螺母在閥體內(nèi),與介質(zhì)直接接觸。開(kāi)閉閘板時(shí),用旋轉(zhuǎn)閥桿來(lái)實(shí)現(xiàn)。這種結(jié)構(gòu)的優(yōu)點(diǎn)是:閘閥的高度總保持不變,因此安裝空間小,適用于大口徑或?qū)Π惭b空間受限制的閘閥。此種結(jié)構(gòu)要裝有開(kāi)閉指示器,以指示開(kāi)閉程度。這種結(jié)構(gòu)的缺點(diǎn)是:閥桿螺紋不僅無(wú)法潤(rùn)滑,而且直接接受介質(zhì)侵蝕,容易損壞。明桿閘閥和暗桿閘閥的主要區(qū)別:暗桿法蘭閘閥的提升螺桿是只旋轉(zhuǎn)而無(wú)上和下移動(dòng),外露的只是一根桿,其螺母是固定在閘板上,通過(guò)螺桿的旋轉(zhuǎn)來(lái)提升閘板,沒(méi)有可見(jiàn)的門(mén)架;明桿法蘭閘閥的提升螺桿是外露的,螺母緊貼手輪且是固定的(不旋轉(zhuǎn)也不軸向移動(dòng)),通過(guò)旋轉(zhuǎn)螺桿來(lái)提升閘板,螺桿與閘板只有相對(duì)的旋轉(zhuǎn)運(yùn)動(dòng)而無(wú)相對(duì)的軸向位移,外觀(guān)為有門(mén)形支架。
