And steam trap selection and application
1. According to the actual operating conditions determined steam trap of inlet and outlet pressure differential. Steam trap inlet pressure refers to the steam pressure due to temperature fluctuations or adjust the throttle valve, the steam trap at the entrance to the lowest pressure of work, Steam trap outlet pressure steam trap refers to the highest possible formation pressure, when working atmosphere into actual differential pressure by steam trap inlet pressure.
2 the steam heating equipment according to normal work in the condensation of water, the correction coefficient k, multiplied by the selection and steam trap displacement.
3 the condensation of water can use the following method to calculate the:
(1) pipeline operation of the condensation of water Q = q0L (1 - Z / %) (kg/h), the formula:
Q: the condensation of water (kg/h),
Q0: light tube produces the condensation of water (kg/h),
L: the distance between trap (m),
Z: insulation efficiency (%)
(2) steam heating equipment operation of the condensation of water Q = VrC train T/Ht, this formula:
Q: the condensation of water (kg/h),
V: heated object size (m3)
R: heated object density (kg/m3)
C: liquid heat kcal/kg (OC).
T: liquid temperature train (OC)
H: steam heat kcal/kg) (
T: heating time
4 all types of steam trap structure and the principle of different performance liquid is endless and same, in the use of different according to different situations, the choice of the steam trap.
