Plate heat exchanger maintenance and cleaning plan_
863 In order to better carry out the maintenance and cleaning of branded plate heat exchangers, we must first formulate a detailed construction plan before operation, and then carry out related maintenance and cleaning work in accordance with the content of the plan. Next, the editor of Diguang Heat Transfer Technology Co., Ltd. will share with you the company's branded plate heat exchanger maintenance and cleaning program. The cleaned metal surface is cleaned, without residual scale, slag, no corrosion, pitting and copper corrosion; after sampling and determining the amount of rust, adhesion and scale, the concentration, temperature and speed of the cleaning solution are determined And cleaning time. Disassembly and assembly of the plate heat exchanger: When disassembling and installing the plate heat exchanger, the bolts should be tightened evenly. When installing each bolt, the plate length of all sides of the plate should be checked. Tighten the bolts by hand as much as possible, and then use a special torque wrench to tighten the bolts symmetrically until all the bolts are tightened. After performing this step, tighten the plate bundle to the required length and size. The length should be measured with a metal ruler. Do not tighten the plate heat exchanger under full medium pressure or during operation. During use, it is very important to keep the plate bundles parallel, otherwise the plates will be permanently deformed and the gasket seal will fail. If the plate heat exchanger leaks after commissioning, the bolts need to be tightened further. If the leakage continues, replace the leaking steel plate surface instead of further tightening the bolts, and remove the steel plate while removing the heat and cold media. For general pipeline cleaning, equipment cleaning methods are divided into physical cleaning methods and chemical cleaning methods. The choice of cleaning method directly affects product quality, cleaning efficiency and cleaning cost. The cleaning method should be selected according to the type of pipes and roads, the nature of the dirt, the source of cleaning materials, the construction environment and the conditions of public works. Cleaning technology includes cleaning materials, cleaning methods, and cleaning processes. One kind of cleaning process can be simple physical cleaning or simple chemical cleaning. It is usually a combination of physical and chemical cleaning techniques. It is necessary to repeat different cleaning operations. The above is an introduction to the contents of the brand plate heat exchanger maintenance and cleaning program.
