Steam trap application design and selection
1. Determine the pressure difference between the inlet and outlet of the steam trap according to the actual working conditions. The inlet pressure of the steam trap refers to the low working pressure of the steam trap at the inlet of the steam trap due to the fluctuation of the steam pressure or the temperature regulation; the outlet pressure of the steam trap refers to the Zui high working back that may be formed after the steam trap Pressure, when discharged into the atmosphere, the actual pressure difference is determined by the inlet pressure of the steam trap.
2. According to the amount of condensate generated by the steam heating equipment during normal operation, multiply by the selected correction factor k, and then select according to the displacement of the steam trap.
3. The amount of condensate can be calculated by the following method:
(1) The amount of condensed water generated during pipeline operation is Q=q0L(1-Z/%) (kg/h). In this formula:
Q: amount of condensed water (kg/h)
Q0: condensed water volume reducing valve (kg/h) generated by the light pipe
L: distance between hydrophobic points (m)
Z: insulation efficiency (%)
(2) The amount of condensed water generated by the steam heating equipment during operation Q=VrCâ–³T, in this formula:
Q: amount of condensed water (kg/h)
V: volume of the object to be heated (m3)
r: density solenoid valve of heated object (kg/m3)
C: specific heat of liquid (kcal/kg.OC)
â–³T: liquid temperature rise (OC)
H: latent heat of steam (kcal/kg)
t: heating time
The structure and principle of various types of steam traps are different, and the performance liquids are not the same. When selecting, different steam traps can be selected according to different use occasions.
