板式换热器以其换热效率高和便于检修等优点,在工业生产中得到广泛应用,但检修时要求比较严格,下面介绍我们在检修中的一些经验.1.准备:检修前,要认真检查准备更换的丁腈胶垫片,要求表面光滑,厚度一致,无横向裂纹、气泡、缺口、老化,无搭接、对接的痕迹,必须有符合要求的力学性能测试证明.使用的粘接剂应在有效期内.检查、清洗换热器本体的固定螺栓、上梁滑动面及辊轮并涂上油脂,保证活动压板前后移动自如.还要测量并记下饭叠长度A.
Plate heat exchanger for its high heat transfer efficiency and easy maintenance, etc., are widely used in industrial production, but the more stringent maintenance requirements, here are some of our experience in the maintenance .1 Preparation: Before the repair, to be conscientious Check the ready to replace the nitrile rubber gasket, requiring a smooth surface, the thickness of the same, no transverse cracks, bubbles, notches, aging, no lap, docking traces must have the required mechanical properties test to prove that the use of adhesives Should be within the validity period .Check and clean the fixing bolts of the heat exchanger body, the sliding surface of the upper beam and the roller and apply grease to ensure the movable front and back of the movable platen.
