style="text-indent:25px">蒸汽輪機(jī)的溫度需減溫減壓裝置來(lái)調(diào)節(jié)的原因：調(diào)節(jié)蒸汽溫度，使鍋爐蒸汽溫度在指定范圍內(nèi)。減溫減壓裝置的制造商告訴我們，蒸汽輪機(jī)的蒸汽溫度非常嚴(yán)格。通常，蒸汽機(jī)的正負(fù)蒸汽溫度不超過(guò)5攝氏度，也就是說(shuō)，蒸汽溫度只能在10攝氏度內(nèi)波動(dòng)。如果蒸汽溫度超過(guò)規(guī)定值，則會(huì)縮短過(guò)熱器，蒸汽管線，蒸汽輪機(jī)和閥門的使用壽命，嚴(yán)重時(shí)會(huì)損壞設(shè)備。蒸汽溫度低于規(guī)定值會(huì)降低設(shè)備的經(jīng)濟(jì)性。當(dāng)蒸汽溫度降低10°C時(shí)，設(shè)備的經(jīng)濟(jì)效率降低0.6%-0.8%。而且由于影響蒸汽溫度的因素很多，為了使蒸汽溫度保持在指定范圍內(nèi)，必須調(diào)節(jié)蒸汽溫度。調(diào)節(jié)蒸汽溫度的方法有很多，并且使用通過(guò)使用減溫器來(lái)調(diào)節(jié)蒸汽溫度的方法。麗水減溫減壓裝置閘閥應(yīng)安裝在設(shè)備的入口處，以便打開(kāi)和關(guān)閉。</p><div

style="text-indent:25px">在減溫減壓裝置的自然頻率和介質(zhì)流動(dòng)所造成的激勵(lì)頻率一致時(shí)，將引起共振，它是減壓閥在一定減壓范圍內(nèi)產(chǎn)生的，而且一旦條件稍有變化，其噪音變化就很大的高頻振動(dòng)；在減溫減壓裝置中重要的便是減溫減壓閥，減溫減壓閥即是通過(guò)控制閥內(nèi)的介質(zhì)流量，將介質(zhì)的壓力減低的，在通過(guò)閥內(nèi)或閥后噴入冷卻水，使介質(zhì)起到降溫的作用的一種儀器。簡(jiǎn)單的說(shuō)，減溫減壓閥就是改變溫度和壓力的儀器。這種儀器在熱電廠、集中供熱、石化、印染、造紙、制藥、冶金等行業(yè)中是很常見(jiàn)的。減溫減壓裝置自動(dòng)控制系統(tǒng)出現(xiàn)故障，應(yīng)立即切換到手操狀態(tài)。</p><p
