Trap is according to the medium pressure, displacement, back pressure and so on many factors to select the most suitable products, must be chosen for trap right, rather than expensive. Trap is a kind of energy-saving products, so choose to a trap, especially high quality steam trap to save energy and improve production efficiency brought by the money will be to buy trap of dozens of times. Here will be on different medium pipeline, to do an analysis in the selection of steam trap, but specific to choose what type and size of trap, it depends on the specific parameters are calculated. For selection of steam trap, high sensitivity, accurate to drainage of steam resistance, no leakage of steam, can improve the utilization rate of steam, reliable performance, high back pressure ratio, long service life, convenient maintenance is preferred. 1, in the production process of heat exchange equipment, drying room, fast heat exchanger, distillation equipment need rapid heating up, are not allowed to have the condensate production of heating equipment, should choose mechanical type of trap. Mechanical type of trap is not affected by working temperature and pressure change, there are water, super-cooling degree is small, no water in the heating equipment, heating equipment to achieve the best working temperature. The free floating ball type steam trap structure is the most advanced, very sensitive, minimum undercooling degree 0 & deg; C, can arrange the condensate saturation temperature, no leakage, the most advantages, can make the heating equipment to achieve the best working efficiency. Is the most ideal production process heating equipment of steam trap. 2, in the steam pipe, heating pipe, small heating equipment, heating equipment, the request is not high temperature steam equipment, should choose hot static type of trap. Hot static type of trap super-cooling degree is big, water temperature low, can make full use of high temperature sensible heat of the frozen water, energy-saving effect is good. Temperature-saturated steam trap of structure is the most advanced, without manual adjustment, is very sensitive, the bigger than 15 ℃ and 30 ℃ cold degrees two bellows for selection, not afraid of cold, small size, can be installed at any position, can repair and replacement of Industrial Valves core in the line to save money and labor, service life is long, the applicable scope is very wide, is the static type of trap heat. 3, in the high temperature and high pressure superheated steam pipeline and equipment, should choose superheated steam trap. Superheated steam trap can be in high temperature, high pressure and small load under the condition of isolated disappear when the temperature of superheated steam condensate. The disc type steam temperature type steam trap using tube for main steam chamber trap heat preservation, advanced structure, in the absence of the condensate, trap tightly shut, work quality is high, service life is long, is a special high pressure superheated steam trap.
are present in just about every facet of modern life.
