Abstract

The invention discloses a method and device for detecting the airtightness of a turbine box assembly, and the tightness of the turbine box assembly is detected through a turbine box assembly detection device. During detection, an outlet sealing plug, an inlet sealing plug and a pedestal of the device enable the outlet, inlet and a core part end opening of a turbine box to be sealed, thereby enabling the inner cavity of the turbine box to form a sealed space. Air is filled in the inner cavity of the turbine box, and the air flow in the turbine box is detected through an air flow meter. Detection data can be directly read from a display unit of the air flow meter. If no air is leaked from the turbine box assembly and the internal air of the turbine box does not flow, the display unit of the air flow meter displays zero; if a discharge valve leaks air, the detection data of the air flow meter is the same as the leakage of air. The method and device can judge whether the tightness of the turbine box assembly is qualified or not through the detection data.
