Traps must use the best quality products, limited funds should be used in the knife's edge. The use of high-quality trap by saving energy and increasing production efficiency of the capital investment than the purchase of the trap a few times higher. Selection of good quality trap can provide a huge economic benefits. The use of a wide range of trap a large amount of 10 million can not be ignored, competent leaders at all levels should attach great importance. Select traps require an accurate and precise gas drainage resistance, high sensitivity, can improve the utilization of steam is not leaking steam, work performance, reliable back-pressure rate, long service life, easy maintenance is the preferred conditions. 1. In the production process of the heat exchanger, drying room, fast heat exchangers, distillation equipment, such as the need for fast heat up, there are not allowed the production of condensate heating equipment, it should use mechanical-type traps. Mechanical-type traps are not working temperature and pressure changes, water that is Pai, undercooling is small, do not water in heating devices, can make heating equipment to achieve optimum operating temperature. Free float steam trap in which the structure of the most advanced, very sensitive, the smallest undercooling 0 ° C, can be ranked saturation temperature condensing water, no steam leakage, merits the highest heating equipment can achieve the best efficiency. Production process heating equipment is the best trap. 2. In steam pipe, with heat pipes, small heating equipment, heating equipment, temperature less demanding equipment using steam, it should be optional static type traps heat. Static thermal cooling degree-type traps, Pai condensing water temperature is low, you can take full advantage of high-temperature sensible heat of condensation of water, energy-saving effect is good. Bellows steam trap in which the structure of the most advanced, no manual adjustment is very sensitive, maximum cooling rate has been 15 ℃ and 30 ℃ for the selection of two kinds of film boxes, not afraid of cold, small size, any position can be installed, In the pipe to repair and replace valve core, save money and labor, life long, very wide scope of application is static-type traps heat boutique. 3. In the high temperature and pressure superheated steam piping and equipment should be selected special superheated steam trap. Superheated steam traps in high-temperature, high pressure, low load operating conditions to isolate the bad disappear superheated steam produced by high-temperature condensate. One disc-type steam trap to use pipe insulation on the steam trap of the main steam rooms insulation, structure is advanced, in the absence of condensate case, trap firmly closed, the work of high quality, long life, is a high-pressure hot special trap steam.
