The effect of steam trap and selection

Function of use and the use of steam trap devices only need to steam. In this equipment must be produced in the condensate water is harmful to the fluid, but also mixed with air and other gas condensate, become the cause of equipment failure and reduce performance. In this case, the most important function of steam trap has three aspects, on the one hand, can quickly eliminate the condensate, on the one hand, to prevent the steam leakage, on the one hand, air condensate gas and other not. Work according to pressure difference in trap, the working pressure difference is hydrophobic valve inlet pressure and outlet pressure ( Back pressure) The pressure difference. If the outlet is the atmosphere, back pressure is zero; If the pressure fluctuation, pressure difference shall be maximum. According to trap maximum displacement choice, should use steam equipment produced by condensation water amount multiplied by the coefficient of standby. Standby coefficient generally take 2 ~ 4 ( Rotary drying equipment spare coefficient 6 ~ 10) 。
