What is the steam leakage rate of a steam trap? Why is the steam leakage rate used to evaluate the performance of a steam trap?

The steam leakage rate of steam traps is categorized into load leakage rate and no-load leakage rate.

Steam leakage rate under load:

The steam leakage rate under load refers to the ratio of steam leakage volume under load to the actual condensate discharge volume during the test period.

Unloaded steam leakage rate:

The no-load steam leakage rate refers to the ratio of no-load steam leakage volume to the maximum condensate discharge volume at the corresponding pressure.

The primary function of a steam trap is to promptly discharge condensate from steam heating equipment or steam piping systems while preventing steam leakage. This enhances the efficiency of steam-using equipment and achieves energy conservation. Therefore, the key indicators for evaluating a steam trap's performance should be its drainage capacity and steam-blocking capability. Based on the definition of steam leakage rate, the magnitude of a steam trap's leakage rate comprehensively reflects the quality of its drainage and steam-blocking performance.
