Dynamic balance of electric regulating pneumatic valve (2)

in the first place, trap old selection criteria:
the top view of the royal chemical industry company is located in huddersfield and Grangemouth ( England) Trap industrial plant performance monitoring and testing, in the fresh steam drain pneumatic valve performance and monitoring and test loss on the basis of the two manufacturers in laboratory, the royal chemical industry company finally content selection of the trap of 'design guide' has been modified. In the new 'guidance', in the selection table changes, including the trap.
trap selection criteria there are many shortcomings of the old, the most obvious is that it didn't mention the equipment type is the method of hydrophobicity and hydrophobicity. The selected hydrophobic pneumatic valve often do not tally with the actual load. Especially, thermodynamic hydrophobic pneumatic valve disk ( The basis) for the selection of the old , especially one who is mistaken for common trap workshop.
, hydrophobic pneumatic valve charging life is too short.
trap performance has expired, and choose not to conform to the actual load.
, one of the most widely used widely in thermodynamic hydrophobic pneumatic valve disk, its energy saving effect is the worst, but compared with inverted bucket hydrophobic pneumatic valve, life is short.
, easy to operate, double metal trap is not stable.
second, selection techniques of trap:
in the new 'guidance', in the selection table changes, including the trap. Trap selection techniques:
, inverted bucket hydrophobic pneumatic valve:
as load and route of choice for all process, for all occasions in need hydrophobic hydrophobic pneumatic valve pneumatic valve head.
floating thermostat hydrophobic pneumatic valve:
to process, especially in the hydrophobic control load. Application or air content (kg under psig） , there is something wrong with the inverted bucket hydrophobic pneumatic valve installed.
and balance pressure pneumatic valve steam traps:
is not important for heating or heating system.
bimetal thermal static hydrophobic pneumatic valve:
for heat pipe with low temperature or heating system under the condition of the frost. Trap types can maximize the use of condensed water is hot or to prevent overheating. The body is stainless steel.
and thermodynamic hydrophobic pneumatic valve disk:
the past experience has shown that as long as it's performance is good, can be used as an inverted bucket hydrophobic pneumatic valve, kg steam heat pipe head pressure and restrict the use of the alternative use of higher vapor pressure or as a replacement. Because of its low energy efficiency, short service life, is not recommended, In huddersfield and Grangemouth factory is not allowed. ）
in hot demand is not high, please replace the thermostat trap trap thermal power will improve the energy efficiency of the disc, and the assurance of life.
machinery trap terms ( The inverted bucket hydrophobic pneumatic valve and float) Water load under the condition of big or small load, guaranteeing free steam condensate, and constant temperature hydrophobic pneumatic valve when the load increases to the condensate accumulation.
