The operation principle for thermostatic steam traps utilizes the temperature difference between steam and condensate.
Thermostatic steam trap working principle.
These are mechanical type of steam traps working on the principle of buoyancy.
Thermostatic traps operate in response to the surrounding steam temperature.
At star up air will enter the steam trap and will be discharged out through the bleed hole.
Thermoliquid bimetal thermowax.
We will also have a brief look at the maintenance procedures of the same.
The expansion of element a leads.
Each operates in a different way and is suited to specific types of application.
Discharge condensate as soon as it is formed unless it is desirable to use the sensible heat of the liquid condensate.
Initially the bucket is resting at the bottom of the steam trap and the valve seat is wide open.
Bimetallic trap is classified as temperature operated traps thermostatic trap and it s by and large the most robust design amongst the various types of traps in common use.
In this article we will learn about thermodynamic and vacuum traps.
The three important functions of steam traps are.
As its name implies the mechanism consists of an inverted bucket which is attached by a lever to a valve.
Working principle of bimetallic steam trap.
In the previous article we discussed the basics of a stream trap and learnt about two types of steam traps mechanical and thermostatic steam traps.
A steam trap is a device used to discharge condensates and non condensable gases with a negligible consumption or loss of live steam steam traps are nothing more than automatic valves they open close or modulate automatically.
Inverted bucket steam trap.
The inverted bucket steam trap is shown in figure 11 3 3.
In an oil filled element type steam trap as shown in the figure the element a expands as the temperature of the condensate rises.
An essential part of the trap is the small air vent hole in the top of the bucket.
Thermostatic trap also known as the temperature trap uses expansion of a bimetallic strip an oil filled element or a flexible below to activate a valve.
It utilizes bimetallic strips of dissimilar metals stacked together in pairs.
