Why Steam Trap Can't Drain Water
Why Steam Trap Can't Drain Water
Steam Traps called hydrophobic or water drainage trap, It's mainly used for steam equipment or piping lines for discharge of condensate and prevent vapors or steam from escaping . There are many different types of steam traps like float type, thermostatic , thermodynamic , etc.
1. Phenomenon
After installation the steam trap , it is not working properly and will affect its use. Sometimes it will cause poor drainage and excessive steam leakage .
After installation the steam trap , it is not working properly and will affect its use. Sometimes it will cause poor drainage and excessive steam leakage .
2 , Analysis of the reasons
( 1 ). Improper pipeline installation or excessive impurities , which caused the steam trap blocked and then does not work.
( 1 ). Improper pipeline installation or excessive impurities , which caused the steam trap blocked and then does not work.
( 2 ). Poor Drainage Reason
a, Pipeline System Steam Pressure is too low, steam and condensate didn't enter the steam trap,
b, The float bucket or the float ball or the lever was stucked,
c. The Disc hole or the flowing channel was blcoked.
d. Thermostatic Dis was broken which caused the blockage.
( 3 ) The main reason for excessive steam leakage
a. It is caused by wear and tear of the valve disc and valve seat ;
b. Drainage holes can not shut itself ;
c. The size of the float bucket or the float ball is too small and can not float.
3 , Prevention and Elimination Measures
( 1) Before installing, steam traps should be checked carefully , and then assembled . Traps should be installed upright at the site below the pipe line , the valve bonnet should be in a vertical position and the inlet and outlet should be at the same level so as to drain condensate easily. Note: The Steam Traps should be installed according to the right flow directioin.
( 2 ) The undrained problem can be checked from the following : steam pressure adjustment system ; checking steam pipe valve is closed or clogged ; appropriate aggravating or replace floats ; If it is stuck to the stem and the sleeve repair or replacement ; clear the clog , and install filter in front of the valve device ; replace the valve .
( 3 ) hydrophobic leak too much time to deal with the following few : If it is a letter and seat wear heavy use leak valve and valve seat grinding grit to make each other , so that the sealing surface to seal ; If the drainage holes can not when itself off , you can check whether there is dirt clogged ; If the volume is too small floating pontoon is not up , may be appropriate to increase the volume of floats .
