How to choose a good steam curing steam trap
Vulcanizing machine is an important rubber plant equipment, how to make the vulcanizing machine is running well is related to product quality, production efficiency, production costs and many other issues, and steam traps affect the normal operation of the vulcanizing machine is a key component. How to choose suitable curing machine steam trap Steam trap normal operation or not, to a large extent affect the steam usage equipment, including the performance and efficiency of the curing machine. At the same time, it also affects the service life of these devices, sometimes causing unexpected accidents and causing huge losses to the enterprises. Therefore, the selection of a trap is very important and should be selected from the following performance bidding of steam traps: (1) Capability to discharge saturated water and supercooled steam Turn into saturated water after releasing heat. If the trap can be saturated water discharge, fresh steam timely replenishment into the vulcanizing machine makes the device always maintained at a higher temperature, can improve production efficiency and product quality. Free float, lever float, float trap can be drained saturated water, undercooling 0-2 ℃. Undercooling refers to the absolute value of the difference between the temperature at which the steam trap can continuously discharge the thermal condensation water and the saturation temperature under the corresponding pressure. Drainage of saturated water drains can be drained at point C, not drained of saturated water traps can only drain at point E, the temperature difference between points C and E is called subcooling. Disc, bimetal, corrugated pipe and other traps can not be discharged due to the high degree of supercooling saturated water is not suitable for vulcanizing machine. (2) The back pressure rate of the trap is also an important indicator of the work of the trap. High back pressure, condensate can be recovered when the back pressure is still high in the case of normal work. (3) trap has a check function, allowing a single vulcanizer to stop working to prevent the flow of condensate back to the vulcanizer adversely affected, resulting in failure, affecting the service life. (4) Select the trap that can be used to overheat the steam. (5) to continuous drainage, and displacement, long life traps. Choosing steam traps can save a lot of energy and capital, of course, perhaps a one-time investment larger, but in the long run is cost-effective, both to ensure product quality, but also can greatly improve work efficiency.
