High temperature pump design should pay attention to the problem

September 22, 2024

1. According to the actual use of conditions to determine the steam inlet and outlet pressure drop. Steam trap inlet pressure is due to fluctuations in steam pressure or temperature regulating valve throttling, steam trap inlet minimum working pressure; steam trap outlet pressure refers to the steam trap may form the highest back pressure When discharged into the atmosphere, the actual pressure difference is determined by the steam trap inlet pressure.
2. According to the amount of condensate generated by the steam heating equipment during normal operation, multiply by the correction factor k and select it according to the displacement of steam traps.
3. The amount of condensate can be calculated by the following method:
(1) The amount of condensate generated during pipeline operation Q = q0L (1-Z /%) (kg / h), where:
Q: Condensation water (kg / h)
q0: condensed water produced by the light valve (kg / h)
L: distance between hydrophobic points (m)
Z: Insulation efficiency (%)
(2) The amount of condensate generated during steam heating operation Q = VrCΔT / Ht, where:
Q: Condensation water (kg / h)
V: Volume of the heated object (m3)
r: Density of the heated object Solenoid valve (kg / m3)
C: Specific heat of liquid (kcal / kg.OC)
△ T: liquid temperature rise (OC)
H: latent heat of steam (kcal / kg)
t: Heating time 4. The recommended values of the correction coefficient K for common usage conditions are recommended in Table 1 below for user's reference.
5. Various types of steam traps structure and principle is different, different performance fluids, when used according to different occasions, choose different steam traps.
