The long-term use of any item can not be separated from the care and maintenance. Murphy laser welding fin tube is no exception. So what are the specific aspects of fin tube maintenance? Generally, when water is used for circulation at the beginning of operation, there may be slight leakage. When the temperature rises to the sterilization temperature, the leakage will disappear by itself. If the leakage does not stop, the finned tube must be compressed a little more. If it is still ineffective, it is necessary to open and check the rubber gasket. It is also possible that the finned tubes are arranged in the order of numbers on the fins, which should be corrected. Regularly check whether the finned tubes are complete, whether there are deposits, coking, rust layer and other scaling adhesion, and clean them immediately. At the same time, it is also necessary to check whether the adhesion between each fin tube and the rubber washer is tight, and whether the rubber washer itself ...

Spiral plate heat exchanger equipment can be broken down, mostly because of quality problems. Compared with the heat transfer surface of other heat exchangers, the heat transfer surface of this heat exchanger is quite thin, that is, 0.5mm, and the allowable high corrosion degree is 0.05mm/ year. The material of common spiral plate heat exchanger equipment usually USES alloy material (304 or 316), 304 is the low cost of austenitic stainless steel, has the ability to resist corrosion to a certain range of organic matter, but the ability to resist hydrochloric acid and sulfuric acid is weak. Spiral plate heat exchanger equipment can be broken down, but also because of its own maintenance problems. Spiral plate heat exchanger equipment is an important component of heat exchange technology in process industrial equipment. The resilient gasket that seals between the various helical fins is a vulnerable part and also an easily aged part under natural conditions. Its service life has an impo...

Spiral plate heat exchanger devices used by the plate on both sides of seal groove, of course, there will be a continuous distribution side, and, in general, actually a side is straight, the other side also is irregular corrugated side. The continuous side edge in the center will provide strong support to the gasket, but the corrugated side edge of the plate and the corrugated side edge of the gasket will also realize just biting each other, which will make the gasket more firmly fixed on the plate, not easy to slide out of the seal groove due to pressure fluctuations and other reasons. The plate used in the helical plate heat exchanger equipment, Murphy experts use new technology and make non-bonding gasket appears to be very easy to install, and the ridgelike projection on the outside of the gasket just matches the groove on the back of the other plate, so that the whole plate group can get stuck when clamping to avoid dislocation. www.murphyfinnedtubes.com Spiral plate heat e...

The application of spacing column in spiral plate heat exchanger is, simply speaking,  refers to the small cylinder or cuboid welded on the spiral plate. The function of spacing column in spiral plate heat exchanger is to keep the spacing of the spiral plate to one. At this time, the rigidity, stability and strength of the spiral plate can be improved. Most of the spiral plate heat exchanger manufacturers use the fixed distance column is made of the car, because the different center of the car caused by the beating of its section center residual boss, in the spiral winding plate surface damage is very large, and reduce the pressure capacity of the cylinder body. Murphy adopted the blanking and shaping process to effectively solve the problem and greatly improve the production efficiency. When it comes to spiral plate heat exchanger equipment, we should pay attention to the middle of Japan and Sweden, carbon steel distance column extruded by wire, the surface after phosphating tre...

Spiral plate heat exchanger in the use of the cleaning and maintenance of its plate will become more important. Murphy experts remind that we need to pay attention to the spiral plate heat exchanger was carried out in actual use, generally don't collapse under the wash, rinse area with medium to flow in the opposite direction, this is not only out of the stuff, but its pressure can not be higher than the pressure of work, at this time we can also for cleaning stainless steel without corrosive chemical cleaning agents. Spiral plate heat exchanger cleaning and maintenance, to pay attention to, if it is used for a long time, the plate is bound to have a certain amount of sediment scaling, so it is bound to affect the effect of heat exchange, in view of this reason, also need to be removed regularly. In the process of cleaning the heat exchanger to break up, with a brown brush to clean the surface dirt, or with a non-corrosive chemical cleaning agent wash. Be careful not to use a meta...

When the spiral plate heat exchanger is used, if water/water is used as the heat transfer medium, the total heat transfer coefficient of the heat exchanger can reach 3~5 times of the heat transfer coefficient of the shell and tube heat exchanger, but the volume of the spiral plate heat exchanger is only about 30% of the shell and tube heat exchanger. When the pressure loss of spiral plate heat exchanger is used, under the condition that the flow of heating carrier is equal, the pressure drop of heat exchanger is significantly reduced, and the water supply pressure is improved from 1.4mpa to 1.6mpa. Regarding the steam consumption of spiral plate heat exchanger, it should be noted that the steam consumption will be significantly reduced, because the original 1.11kg/s has been reduced to 0.97kg/s, and the steam should be saved per hour :(1.11-0.97)×3600/1000=0.504t. https://www.alibaba.com/product-detail/Murphy-Steam-Plate-Heat-Exchanger-China_62423628044.html?spm=a2700.icbuShop.414...

Remove dirt or plate scaling from spiral plate heat exchangers. For new systems, Murphy experts suggest that cleaning should be done once a week, depending on the actual situation. Clean plate surface scale (mainly CaCO3). When, choose to contain 0.3 sulfamic acid solution or containing 0.3 ullotopine, 0.2 aniline, 0.1 potassium thiocyanate 0.8 nitric acid solution as the cleaning solution, cleaning temperature 40 ~ 60℃. Spiral plate heat exchanger without removing equipment for chemical immersion cleaning, attention should be paid to open the inlet and outlet of the heat exchanger cooling medium, or when the installation of the equipment is installed on the inlet and outlet of the medium over DN25 clean mouth, at this time should have good cleaning fluid injected into the device, wash clean with clear water after soaking should also be the residual acid, pH 7 or higher. https://www.alibaba.com/product-detail/Murphy-Steam-Plate-Heat-Exchanger-China_62423628044.html?spm=a2700.icbuS...

Spiral plate heat exchanger channel selection: for the cold and hot fluids for heat exchange, first of all, it is necessary to pay attention to the unclean and easy to scale fluid suitable to go through the tube, because the tube cleaning is more convenient; In this case, the corrosive fluid is suitable for pipe passage, after which the tube bundle and shell can be avoided from being corroded at the same time; The fluid with high pressure should go through the pipe to avoid the shell to bear the pressure. For the selection of the channel of spiral plate heat exchanger, the saturated steam should go through the shell path, because the heat transfer coefficient of steam condensation has nothing to do with the flow rate, and the condensate is easy to discharge. If the temperature difference between the two fluids is large, it is necessary to pay attention to the use of fixed tube spiral plate heat exchanger equipment, it is appropriate to make the heat transfer coefficient of the fluid t...

Speaking of spiral plate heat exchanger heat transfer efficiency, the medium flow in the narrow channel, for its rotating centrifugal, actually is also will be affected by distance column approach, at this point, also will be relatively easy to obtain low Reynolds number turbulence (but not much pressure lung), coefficient of heat transfer is very high, high up to 2500 kcal / 2 · h · ℃, its thermal efficiency is generally 1 to 3 times or other heat exchanger. Murphy spiral plate heat exchanger is characterized by the recovery of low-temperature heat. With this device, heat exchange can still be carried out under the condition that the temperature difference between the two fluids is relatively small. In other words, the heat exchanger can be used to recover low-temperature heat and waste heat. https://www.alibaba.com/product-detail/Murphy-SS304-SS316L-SMO254-C276-Titanium_62424886016.html?spm=a2700.galleryofferlist.0.0.11491aee3sTrQP Murphy spiral plate heat exchanger has less ...
