After the plate heat exchanger has operated for a period of time, the pressure drop is too large due to fouling on the plate surface.. ③ The flow distribution of multiple plate heat exchangers operating in parallel is uneven. ② It is best to use softened water for the secondary circulating water. Reasons: ① Insufficient medium flow on the primary side, resulting in a large temperature difference on the hot side and a small pressure drop. Hope that the introduction of plate heat exchangers can be helpful to you, follow us for more news! If you don’t understand those aspects, you can consult us and we will have professionals to answer you.8 nitric acid solution containing 0.3 urotopin, 0.2-0. 3.
The pipeline of the operating system is not normally purged, especially when many dirt (such as welding slag, etc. Example: In 2000, our factory provided a BR10 plate heat exchanger for users in Xinjiang, which is used in a water-to-water heat exchange central heating system. ②
The cold side temperature is low, and the cold and hot ends have low temperatures. Finally, circulate the clean water several times to control the Cl mass concentration in the clean water below 25 mg/I. The Heat Exchangers FHC060B cycle cleaning time is 10-15 min.3 MPa, making the secondary network hydraulic balance serious Imbalance. When disassembling and cleaning, soak the plate in the cleaning solution for 30 minutes, then use a soft brush to gently brush the scale, and finally clean it with water.
The heating temperature cannot meet the requirements.3 sulfamic acid solution or 0. The design temperature of the primary water supply is 130℃. If the mechanical backwashing method without disassembly is adopted, a nozzle should be connected to the medium inlet and outlet pipes in advance, the equipment is connected to the mechanical cleaning vehicle, and the cleaning fluid is injected into the equipment in the opposite direction of the medium flow.15 m/s. When the water temperature is not more than 95℃, the concentration of Ca and Mg should not be more than 2 mmol/L; when the water temperature is more than 95℃, the concentration of Ca and Mg should not be more than 0. ④The internal scale of the heat exchanger is serious
