  1. 拆卸板式换热器前,测量并记录板式管束的压缩长度,重新安装时根据尺寸选择零件。
  1. Before disassembling the plate heat exchanger, measure and record the compression length of the plate tube bundle, and select the parts according to the size when reinstalling.
  2. 检查密封垫片是否卡在两块板之间的槽内。如果需要用螺丝刀小心分离,将螺丝刀插入易剥落的部位,然后沿其外围分开。
  2. Check whether the sealing gasket is stuck in the slot between the two plates. If it is necessary to separate carefully with a screwdriver, insert the screwdriver into the flaking area and then separate along its periphery.
  2. 更换垫片时,必须用丙酮或其他酮类有机溶剂擦拭垫片沟槽。然后用刷子将合成树脂均匀地涂在沟槽上。
  2. When replacing gaskets, the grooves of gaskets must be wiped with acetone or other ketone organic solvents. Then the synthetic resin is evenly coated on the groove with a brush.
  3.检查热风炉换热器板是否穿孔。一般放大镜使用5次。热风炉作为一种热动力机械,在20世纪70年代末开始在我国广泛应用。它已成为电力热源和传统蒸汽动力热源的替代产品。通过长期的生产实践,人们认识到只有以热风为介质和载体才能大大提高热效率和热工效果。传统的电热源和蒸汽火电在输送过程中往往配备多个循环风机,从而间接形成热风进行干燥或加热。
  3. Check whether the heat exchanger plate of hot blast stove is perforated. Usually the magnifying glass is used five times. Hot blast stove, as a kind of thermal power machinery, began to be widely used in China in the late 1970s. It has become an alternative product of electric power heat source and traditional steam power heat source. Through long-term production practice, people realize that only using hot air as medium and carrier can greatly improve thermal efficiency and thermal effect. Traditional electric heat sources and steam thermal power are often equipped with multiple circulating fans in the transmission process, thus indirectly forming hot air for drying or heating.
  4. 如果在介质进、出口的短管道和通道中发现杂物,则说明过滤器失效。清理。常用的清洗方法有反冲法、手工清洗法、化学清洗法等。
  4. If impurities are found in the short pipes and passages at the inlet and outlet of the medium, the filter will fail. Clear. Commonly used cleaning methods are backwash, manual cleaning, chemical cleaning and so on.
  5、换热器板疤时,不要用钢丝刷或钢丝刷清洗,以免加速钢板的腐蚀。用清洁剂去除盘子上的污渍或锈迹。记住,用于清洁的水不应该含有盐、硫或其他酸性成分。

  5. When heat exchanger plate scar, do not use wire brush or wire brush to clean, in order to avoid accelerating the corrosion of steel plate. Use detergent to remove stains or rusts on the plate. Keep in mind that water used for cleaning should not contain salt, sulfur or other acidic ingredients.
  6. 取出钛板时,严禁与明火接触,以免氧化。检查垫圈是否有老化、变质和裂纹等缺陷。不要刮硬物体表面。
  6. When removing the titanium plate, it is strictly forbidden to contact with open fire in order to avoid oxidation. Check whether the washer has defects such as aging, deterioration and cracking. Do not scrape hard surfaces.
  7、严禁密封垫片和换热器板表面积聚固体颗粒,如砂子、铁渣等。
  7. It is strictly forbidden to accumulate solid particles on the surface of sealing gaskets and heat exchanger plates, such as sand and iron slag.
  8. 检查换热器板是否有局部变形。如果超过允许值,则应进行修剪或替换。
  8. Check whether the heat exchanger plate is locally deformed. If it exceeds the allowable value, it should be pruned or replaced.
  在热风炉换热器的拆除和更换中必须注意以上问题,以提高设备的维修和效率。燃煤热风炉主要用于鸡、鸭等养殖棚、蔬菜棚的加热保温。
  In order to improve the maintenance and efficiency of the equipment, attention must be paid to the above problems in the removal and replacement of the heat exchanger of the hot blast stove. Coal-fired hot blast stove is mainly used for heating and heat preservation of chicken and duck breeding shed and vegetable shed.
