上海淞江減震器集團(tuán)是國(guó)內(nèi)第一批制造管道減振設(shè)備的廠家，主要生產(chǎn)橡膠接頭、可曲撓橡膠接頭、阻尼彈簧減振器、橡膠隔震器、金屬和非金屬補(bǔ)償器、管道伸縮器等管道減振給排水設(shè)備。技術(shù)創(chuàng)新是淞江集團(tuán)多年來(lái)孜孜不倦的追求，也正是淞江產(chǎn)品深受市場(chǎng)一致好評(píng)的根本原因。
目前全球海水淡化技術(shù)超過(guò)20余種，包括冷凍法、反滲透法、低溫多效、多級(jí)閃蒸、電滲析法、 壓汽蒸餾、露點(diǎn)蒸發(fā)法、水電聯(lián)產(chǎn)、熱膜聯(lián)產(chǎn)以及利用核能、太陽(yáng)能、風(fēng)能、潮汐能海水淡化技 術(shù)等等，以及微濾、超濾、納濾等多項(xiàng)預(yù)處理和后處理工藝。
從大的分類來(lái)看，主要分為蒸餾法(熱法)和膜法兩大類，其中低溫多效蒸餾法、多級(jí)閃蒸法和反滲 透膜法是全球主流技術(shù)。
一般而言，低多效具有節(jié)能、海水預(yù)處理要求低、淡化水品質(zhì)高等優(yōu)點(diǎn);
反滲透膜法具有投資低、能耗低等優(yōu)點(diǎn)，但海水預(yù)處理要求高;
多級(jí)閃蒸法具有技術(shù)成熟、運(yùn)行可靠、裝置產(chǎn)量大等優(yōu)點(diǎn)，但能耗偏高。
一般認(rèn)為，低多效蒸餾法和反滲透膜法是未來(lái)方向。
海水處理意味著靠近海邊，潮濕的海風(fēng)以及含鹽量比較高的海水對(duì)海水處理設(shè)備有著極高的要求 ：耐腐蝕!特別是自己接和海水接觸的管道配件--柔性軟接頭!
近海的環(huán)境，近乎于鹽霧環(huán)境，那么在鹽霧環(huán)境下應(yīng)該如何選擇橡膠接頭的類型?
柔性軟接頭的選擇需要考慮工作環(huán)境和管道介質(zhì)。
海水處理限制了柔性軟接頭的橡膠材質(zhì)必須酸堿：三元乙丙橡膠!
海水環(huán)境限制了橡膠接頭法蘭的選擇：304!
304法蘭三元乙丙柔性軟接頭特點(diǎn)：
1.特殊法蘭，耐腐蝕，特別是在海水環(huán)境下，經(jīng)久耐用;
2.三元乙丙橡膠，耐弱酸弱堿，用于海水處理毫無(wú)壓力;
3.體積小、重量輕、彈性好、安裝維修方便。
4.安裝后可吸收管道震動(dòng)產(chǎn)生的橫向、軸向、角向位移;不受管道不同心，法蘭不平行的限制。
The global desalination technology for more than 20 species, including freezing method, reverse osmosis, low-temperature multi effect, multi stage flash, electric dialysis method, pressure steam distillation, dew point evaporation, water and electricity production, hot film co production and use of nuclear energy, solar energy, wind energy, tidal can desalination technologies and microfiltration, ultrafiltration, nanofiltration and other several pre-processing and post-processing technology.
From the point of view of the classification of large, mainly divided into distillation (thermal) and membrane method, the low temperature multi effect distillation, multi-stage flash distillation method and reverse osmosis membrane method is the world's mainstream technology.
Generally speaking, low multi effect has the advantages of energy saving, low water pretreatment requirements, low water quality and high quality;
The reverse osmosis membrane method has the advantages of low investment and low energy consumption;
The multi-stage flash method has the advantages of mature technology, reliable operation, large output device, but high energy consumption.
It is generally believed that the low multiple effect distillation and reverse osmosis membrane are the future directions.
Seawater treatment means that close to the beach, moist sea breeze and the salt content of water of sea water processing equipment has a high requirement: corrosion. Especially their connection and contact with seawater pipe fittings, flexible connector!
Offshore environment, almost in the salt fog environment, then in the salt fog environment should be how to choose the type of rubber joints?
The choice of flexible flexible joints should be considered in the working environment and pipeline medium.
Seawater treatment limits the flexible connector of the rubber material must be acid: three epdm!
The seawater environment limits the choice of the flange of the rubber joint: 304!
