Selection and application of steam trap
1 Determine the pressure difference between the inlet and outlet of the steam trap according to the actual working conditions. The inlet pressure of steam trap refers to the minimum working pressure at the inlet of steam trap due to the fluctuation of steam pressure or the throttling of temperature regulating valve; The outlet pressure of steam trap refers to the maximum possible working back pressure behind the steam trap. When discharged into the atmosphere, the actual pressure difference is determined by the inlet pressure of steam trap
recently 2 According to the condensate volume produced by the steam heating equipment during normal operation, multiply by the selection correction coefficient K, and then select according to the drainage volume of the steam trap
3. The condensed water volume can be calculated by the following methods:
(1) the condensed water volume produced during the operation of the pipeline and with the written promise of quality assurance and maintenance of the external insulation system, q=q0l (1-z/%) (kg/h). In this formula:
Q: condensed water volume (kg/h)
q0: condensate water produced by smooth tube (kg/h)
l: distance between drainage points (m)
z: insulation efficiency (%)
(2) condensate water produced by steam heating equipment during operation q=vrc △ t/ht, In this formula:
q: condensed water volume (kg/h)
v: volume of heated object (M3)
r: density of heated object (kg/m3)
c: specific heat of liquid (kcal/)
△ T: temperature rise of liquid (OC)
h: latent heat of steam (kcal/kg)
t: heating time
4 The structures and principles of various types of steam traps are different, and the performance fluids are different. When selecting, you can choose different ones according to different application occasions. 1 Maximum experimental torque: ly10nm, 20nm, 50nm, 100nm, 200nm steam traps
