由于清潔的艱難程度是隨著垢層厚度或堆積的添加而靈敏增大的，所以清潔距離時(shí)間不宜過(guò)長(zhǎng)，應(yīng)依據(jù)生產(chǎn)設(shè)備的特色，板式熱交換器換熱介質(zhì)的性質(zhì)，侵蝕速度及運(yùn)轉(zhuǎn)周期等狀況定時(shí)進(jìn)行檢查，修補(bǔ)及清潔。選用化學(xué)清潔時(shí)，要依據(jù)實(shí)踐請(qǐng)況和水質(zhì)的不一樣所結(jié)垢的垢質(zhì)進(jìn)行剖析化驗(yàn)別離制造藥劑清潔。
    依據(jù)板式熱交換器的方式，應(yīng)在換熱器的兩頭留有滿足的空間來(lái)滿足前提(操縱)清潔、修補(bǔ)的需求。固定管板式換熱器在設(shè)備時(shí)，兩頭應(yīng)留出滿足的空間以便能抽出和替代管子。而且，用機(jī)械法清潔管內(nèi)時(shí)，兩頭都可以對(duì)管子進(jìn)行沖刷操縱。浮頭式換熱器的固定頭蓋端應(yīng)留有滿足的空間以便能從殼體內(nèi)抽出管制，外頭蓋端有必要也留出一米以上的方位以便裝拆外頭蓋和浮頭蓋。U形管式換熱器的固定頭蓋應(yīng)留出滿足的空間以便抽出管制，也可在其相對(duì)的一端留出滿足的空間以便能拆開(kāi)殼體。

Due to clean difficult degree is sensitive with the add of scale thickness or accumulation increases, so clean distance time shoulds not be too long, should be based on the equipment features, the nature of the heat transfer medium, erosion rate and operating state such as cycle time for inspection, repair and clean.When choosing chemical cleaning, should be based on the practice condition and water quality is not the same, please analyzes the scale and quality of fouling in the laboratory by manufacturing pharmaceutical clean separation.On the basis of the heat exchanger, with satisfy the space should be at the two ends of the heat exchanger to meet the needs of premise (control) cleaning, repair.When fixed tube plate heat exchanger equipment, two head should be set aside to meet space so that it can take out and replace the pipe.And, when clean pipe by mechanical method, can be carried out on the pipe flushing control both ends.Fixed epicranium end of floating head heat exchanger should be left free to meet from housing to take control, outside the cranium end so it is necessary to also set aside a metre above the position of casual split cranium and floating head cover.Fixed cranium of u-tube heat exchanger should be set aside to meet space in order to take control, can also be used in its relatively set aside to meet at the end of the space to open shell.
