Many users have found that some of the finned tubes are not carefully maintained, which leads to short service life. How to maintain the finned tubes to make their life longer? Today, I have tidied up the following points for attention: Finned tubes are installed through high frequency welding technology plus flaky fins. Do not impact extrusion during use, so it will be easy to deform, and even more affect the cooling effect.
Because of the spiral distribution of finned tube scales, there will be some sediments and rust layer in long-term use, so we need to clean in time.
Finned tube excuses check whether the interface is loose and the pads fall off.
The finned tube should be exposed to the outside to avoid falling rain, keep as dry as possible, not too close to the ground, so as to avoid the erosion of the finned tube by irrigation in greenhouse greenhouse.
Through the maintenance of finned tubes, the service life of finned tubes will increase greatly. The long-term use of any item can not be separated from careful maintenance and maintenance, and fin tube is no exception, so from what specific aspects to maintain fin tube? Let's look at the introduction of finned pipe network experts.
1. Check regularly whether the finned tube Wuxi cleaning is perfect or not, whether there are deposits, coking, rust layer and other fouling adherence, and immediately clean. At the same time, it is necessary to check whether the finned tubes are closely bonded to the rubber gasket and whether the rubber gasket itself is in good condition, so as to avoid leakage caused by rubber gasket degumming and damage.
2. Plate heat exchanger pressure nuts and upper and lower guide rods should be often used to add lubricating grease to lubricate.
3, the instrument adjustment should be specially responsible, and strictly enforce the operation rules for operation and maintenance.
4、当需更换的橡胶垫圈或修补脱胶部分时，需将该翅片管取下，放在桌上，将旧垫圈拆下，或在脱胶处将翅片管凹槽的胶水遗迹用细砂纸擦尽，再用四氯化碳或三氯乙 烯等溶剂把凹槽内的油迹擦尽，再把新橡胶的垫圈的背部用细砂纸擦毛，同样用四氯化碳或三氯乙烯溶剂把油迹擦尽。然后在凹槽和橡胶垫圈背面均薄薄敷上一层胶 水，待稍干一下，以不粘手指，但仍发粘为度，即将橡胶垫圈嵌入槽内，四周压平，敷一层滑石粉，随即将翅片管装上设备机架轻轻夹紧。根据胶水说明书要求隔大 周皇族一段时间即可投产使用。
4. When replacing the rubber washer or repairing the degumming part, the finned tube should be removed and placed on the table. The old washer should be removed, or the glue vestiges of the groove of the finned tube should be rubbed out with fine sandpaper at the degumming place. The oil traces in the groove should be rubbed out with carbon tetrachloride or trichloroethylene, and the back of the new rubber washer should be used. Fine sand paper is used to rub hair, and the oil stains are also wiped out with carbon tetrachloride or trichloroethylene solvent. Then apply a thin layer of glue on the back of the groove and rubber washer, wait for a little drying, in order not to stick fingers, but still stick, that is, rubber washer is embedded in the groove, flat around, coated with a layer of talcum powder, and then the finned tube is installed on the equipment rack and lightly clamped. According to the requirements of the glue instruction, the royal family can be put into operation for a period of a week.
5. Every time the finned tube is re-compressed, attention should be paid to the calibration position of the last compression, so as not to overpress the rubber washer, so as to reduce the service life of the washer.
6. When replacing rubber gaskets of finned tubes, all the sections should be updated so as to avoid uneven clearance between the finned tubes and affect the heat transfer effect. 专家表示说：一般在操作开始使用清水进行循环时，可能有轻微的漏泄，到温度升到杀菌温度时，漏泄将自行消失。如果漏泄仍不停止，须将翅片管再压紧一些。如果仍不见效，尚须打开检查橡胶垫圈的情况，亦有可能是翅片管末按片上号码顺序排列，则应予纠正。
Experts said: Generally, when the operation begins to circulate with clean water, there may be a slight leakage. When the temperature rises to sterilization temperature, the leakage will disappear by itself. If the leakage does not stop, the finned tube must be pressed further. If it is still ineffective, it is necessary to open the rubber washer to check the situation, or it is possible that the fin tube end is arranged in the order of on-chip number, it should be corrected.辛苦整理.转载请注明http://www.wxsxsjx.com
