What Is the Main Reason for the Breakdown of the Analysis Board?
1. Construction problem: the system is only equipped with a filter, and no electronic water treatment device is installed, so it is difficult to ensure that the Plumbing of the semi welded plate heat exchanger will not scale. In addition, if the filter is not cleaned in a timely manner, even small sand and gravel that do not pose a threat to the equipment will remain in the circulating water, but it will pose a risk of wear and tear to the plates.
2. Quality issue: The heat exchange surface of the plate is quite thin, which is 0.5mm, and the maximum allowable corrosion rate is 0.05mm/year. The material of ordinary equipment usually uses alloy materials (304 or 316). 304 is a very cheap type of austenitic stainless steel, which has corrosion resistance to a specific range of organic matter, but weak resistance to hydrochloric acid and sulfuric acid. The equipment material of the air conditioning host is 304, so after 8 years of use, it is certain that the board will puncture and corrode.
3. Maintenance issue: The semi welded plate heat exchanger is an important component in the heat exchange skills of process industrial equipment. The gasket that seals between various plates is a vulnerable component and also a component that is prone to aging under natural conditions. Its service life has a significant impact on the service life of the equipment. If these sealing gaskets harden, lose their original elasticity, and are not retightened or replaced in a timely manner, it can cause the semi welded plate heat exchanger to show the appearance of dripping.
