Principles of selection of steam traps
① if the pipeline equipment has the fastest heating speed, strict temperature control, and to maintain in the heating equipment can not accumulate condensate water, you should choose to discharge saturated water mechanical traps;
② if heating equipment has greater heating area, does not require heating, heating temperature is not strict, and can be required to accumulate a certain amount of condensate, the use of thermal static type steam traps;
③ according to the use of equipment, the number of displacement, traps must be considered safety factor; ④ trap is to determine the displacement by pressure difference.
