Through the recent market survey and return visits, we found that many customers do not understand the cleaning of plate heat exchanger plates well. Today, the editor will share the relevant information with you, hoping to attract everyone's attention and let everyone Have a deep understanding of plate heat exchangers. In this way, everyone can know what to buy when using a plate heat exchanger, and not afraid of being deceived, I hope to inspire and help everyone. Since the plate heat exchanger has a large number of plates, it needs to be cleaned piece by piece, and all of the new pads need to be replaced. Therefore, during overhaul, it is generally suspended from the installation position and disassembled and overhauled at a suitable place. When the scale on the plate is very thin and the scale layer is easily soluble in water, the plate can be placed in a special water tank and scrubbed with soft fiber brown hair, or it can be washed with 1-29cg / cmz of pressure water or low-pressure steam. Under no circumstances should the use of acetylene flames be heated. Before overhaul, the gaskets to be replaced need to be inspected carefully. The surface must be smooth, consistent in thickness, no transverse cracks, no bubbles, no gaps, no aging, no overlap and no traces of overlap. Remove the tube first, and then loosen the fixing bolts in the diagonal direction. After the system gas, pressure, temperature and other parameters meet the maintenance requirements, they can enter the site construction. The adhesive used should also be within the expiration date. For perforated plates, hydrogen arc welding can be used to repair and smooth them. Before disassembly, the medium inlet valve should be blocked, and the high-pressure side valve should be blocked first, and then the outlet valve should be blocked, and the heat exchanger should be slowly cooled down to 40 ° C before being discharged, and then the connected pipes should be removed for overall lifting and removal.
