The selection methods of trap[2012-05-31] ¡û·µ»Ø
Under actual use conditions to determine the differential pressure of the inlet and outlet of the steam trap. Inlet pressure of the steam trap is due to the fluctuations of the vapor pressure or temperature regulating throttle valve, steam trap at the entrance to the minimum working pressure; the outlet pressure of the steam trap is the maximum operating back pressure refers to the steam trap may form when discharged into the atmosphere, the actual differential pressure is determined by the steam trap inlet pressure. According to the condensation of water steam heating equipment in normal working hours, multiplied by the selected correction factor k, then be selected in accordance with the displacement of the steam trap.
Condensed water can be calculated as follows:
(1) pipeline running the condensation of water Q = q0L (1-Z /%) (kg / h), this formula:
Q: condensation of water (kg / h)
q0: fluorescent tubes produced by condensation of water (kg / h)
L: distance between the hydrophobic point (m)
Z: insulation efficiency (%)
(2) steam heating equipment is running the condensation of water Q = VrC of ¡÷ T / Ht, this formula:
Q: condensation of water (kg / h)
V: the volume of the object to be heated (m3)
r: the density of the object to be heated (kg / m3)
C: the liquid specific heat (kcal / kg.OC)
¡÷ T: liquid temperature rise (OC)
H: Steam latent heat (kcal / kg
        t: heating time
