What are the problems of plate heat exchanger?
2022 / 09 / 27
The welding connection between the laser welded finned tube and the tubesheet is to make holes and grooves on the tubesheet. After the finned tube penetrates into the tubesheet hole and aligns with it, the finned tube is connected with the tubesheet by welding to achieve the purpose of sealing and tensile detachment. It is used to realize the welding connection between the finned tube and the tube plate. Customized classification of laser welded finned tubes: 1. Linear spiral surrounding electric heating radiation tube: this electric heating radiation tube is composed of a heat-resistant alloy steel casing and a heater, which is generally wound by an electric heating wire on a heat-resistant insulating ceramic tube core with a spiral groove. 2. Ribbon spiral surrounding electric heating radiation tube: the heating element of this heater is wound by resistance tape, and the tube core is mostly composed of multiple grouped tube cores. Under the same surface load, the thermal radiation surface is large, and the materials can be saved. Generally, this form is used for high-power point heating radiation tubes. 3.

Heat exchange and heating process of finned tube heat exchanger
2022 / 09 / 27
In general, the spacing and fin height of finned tube heat exchanger mainly affect the fin ratio. The fin ratio has a great relationship with the film heat transfer coefficient of the medium inside and outside the tube. If there is a large difference between the film heat transfer coefficient inside and outside the tube, the finned tube with a large fin ratio, such as steam heating air, should be selected to a certain extent. When the medium on one side has phase change, the difference of heat transfer coefficient will be large, such as the exchange of cold and hot air. When the hot air drops below the dew point, the finned tube heat exchanger can be used. In the case of air and air heat transfer without phase change, bare tubes are usually suitable for water and water heat exchange of finned tube heat exchanger. Of course, low finned tubes can also be used, because this is a weak heat transfer coefficient, and strengthening either side of them has a certain effect. However, the effect of excessive winging ratio is not obvious. The perfect situation is that the contact area inside and outside the pipe is strengthened at the same time. Threaded pipe or grooved pipe can be used. The fin distance of finned tube heat exchanger mainly considers factors such as ash deposition, dust deposition, easy cleaning, etc., and strictly meets the requirements of equipment on pressure drop. When arranging, the spacing between pipes is not easy to be too large, and generally more than 1mm is suitable for pipe laying. In the process of heat exchange, when the air flows through the finned tube heat exchanger, the positive and negative surfaces of the fin mainly participate in the heat exchange. There is only a small amount of radiation heat transfer in the middle of the two finned tubes, and the heat transfer effect is not obvious.
Operating procedures and scale position of spiral finned tube
2022 / 09 / 27
During the operation of spiral finned tubes, it is necessary to regularly check whether each finned tube is perfect, whether there is sediment, coke, rust layer and other scales attached during the use, and clean them immediately. At the same time, it is also necessary to check whether each fin tube is tightly bonded to the rubber gasket and whether the rubber gasket itself is intact to avoid leakage caused by rubber gasket degumming and damage. The compression nuts and upper and lower guide rods of the plate heat exchanger shall be lubricated frequently with lubricating grease. To a certain extent, each instrument adjustment of spiral finned tube shall be in the charge of a specially assigned person, and the operation and maintenance shall be carried out in strict accordance with the operating procedures When the rubber gasket needs to be replaced or the degummed part needs to be repaired when the spiral finned tube is in use, the finned tube needs to be taken down and put on the table to remove the old gasket, or the glue residue in the fin tube groove is wiped off with fine sandpaper at the degumming point, and then the oil stain in the groove is wiped off with carbon tetrachloride or trichloroethylene and other solvents, and the back of the new rubber gasket is wiped off with fine sandpaper, Also use carbon tetrachloride or trichloroethylene solvent to wipe up the oil stains. Then apply a thin layer of glue on the back of the groove and the rubber washer. After a little drying, the rubber washer is embedded into the groove, flattened around, and coated with talcum powder. Then, install the fin tube on the equipment rack and gently clamp it. According to the requirements of the glue specification, it can be put into operation after a period of time for the royal family of the Zhou Dynasty.

Four Methods of Finned Tube Radiator
2022 / 09 / 27
In the case of natural heat conduction of finned tube radiator, the air flow is driven by the temperature difference. The surface temperature of high-efficiency finned tube is very high, but the temperature difference cannot drive the air flow. In this way, the heat energy will stay on the surface of the fin, mainly because the air also has a certain viscosity. In the case of insufficient driving force, most of the warm air sticks near the plate fin type and does not flow, leading to the reduction of heat exchange efficiency. The steel finned tube radiator has a high bearing pressure, which is increased by 20% from the industry standard mpa to the enterprise standard. Finned heat sink tubes and steel aluminum composite rolled spiral finned heat sink tubes are more widely used in industrial drying systems and various special drying equipment. Set the distance between the plate fin height and the plate fin type of each heat sink tube, cooperate with the use of the exhaust air volume of the convection fan, and fully ensure that more heat removal effects are achieved in the practical application of heat sink tubes. Whether the steel finned tube radiator and the steel aluminum composite finned tube heat exchanger in the industrial production drying equipment can give full play to the better heat removal effect should be fully considered. The heat exhausting spiral finned tube used in the steel finned tube radiator was earlier produced and processed by winding, while the more stable and reliable production process was high-frequency welding. Finned tube radiator can be divided into four methods: air cooling, air cooling, water cooling, and heat pipe cooling. The following four methods are introduced in detail. Finned tube radiator is air cooling, and finned tube radiator ai
