板式換熱器清洗后板片安裝正確的順序
1先用卷尺測量一下產品兩夾板內的尺寸，并做好記錄（以便最后組裝）
2將板式換熱器的各法蘭拆開，并移到空地。打開排污口放出換熱器內殘留的
水。
3.當水排盡后，將板式換熱器平臥（帶法蘭的一面向下），然后均勻的松開換熱器夾板上的螺栓，注意要對稱松開、用力均勻，以免板片因兩側壓力不等出現竄位或變形。
4、所有螺栓松開后，先將最上面的一張夾板移開，然后將所有板片一張一張拿出來進行清洗。一定注意板片與密封墊的位置
5.清洗方法：可以用手工清洗或用機械清洗，建議使用一些清洗劑（如氨基磺酸清洗液或者質量百分比為5%的稀鹽酸+8%的B-125緩蝕劑+2%的AP221表面活性劑組合清洗液）將板片和密封墊上的污濁清洗掉，以免組裝時打滑或竄位，導致密封性能不好。手工清洗時，一定要使用軟毛刷蘸上清洗液來清洗。注意不要將板片和密封墊損壞。
6、組裝：將清洗好的跡紶管咳攮糾歸穴害膜板片和密封墊依次按照原先拆的順序組裝起來，按照拆卸時的方法將夾緊板夾緊到原先記錄的尺寸。緊好后以1.25倍的工作壓力進行打試驗，確保產品無泄露。
5. Cleaning method: It can be cleaned by hand or by machine. It is suggested that some cleaning agents (such as aminosulfonic acid cleaning solution or dilute hydrochloric acid with 5% mass percentage + 8% B-125 corrosion inhibitor + 2% AP221 surfactant combined cleaning solution) be used to clean the dirt on the plates and gaskets, so as to avoid slippage or displacement during assembly. The sealing performance is not good. When cleaning by hand, be sure to use a soft brush dipped in the cleaning fluid to clean. Be careful not to damage the plates and gaskets.
6. Assemble: assemble the cleaning traced tube, cough-curing acupoint-damaged diaphragm sheet and sealing gasket in turn according to the original disassembly order, and clamp the clamping plate to the original recorded size according to the disassembly method. After tightening, test with 1.25 times the working pressure to ensure no leakage of the product.
