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 as follows: (1) The amount of condensate generated during pipeline operation Q = q0L (1-Z /%) (kg / h), where Q is the volume of condensate (kg / h) : The amount of condensate produced by the light pipe (kg / h) L: The distance between the hydrophobic points (m) Z: Insulation efficiency (%) (2) The amount of condensate generated during steam heating operation Q = VrCΔT / Ht, In this equation, Q is the volume of condensate (kg / h) V is the volume of the heated object (m3) r is the density of the heated object (kg / m3) C is the specific heat of the liquid (kcal / kg.OC) : Liquid temperature rise (OC) H: latent heat of steam (kcal / kg) t: heating time 4. Various types of steam traps have different structures and principles, different performance fluids, when used according to different requirements Occasion, choose a different steam trap
The fatigue resistance of plastic-coated steel wire ropes is good. For example, the durability of steel wire ropes with nylon coating and nylon core is about 2 times that of ordinary hemp core or metal core (see rope core) steel wire ropes. Plastic-coated steel wire ropes are mainly used in mine hoisting cages, hoisting machinery in meat processing plants, seagoing ship anchors, towing and fishing operations, fishing vessel trawls, etc.
