Description

[0001] The invention relates to the technical field of sealing performance testing of enamel inner tanks, and in particular to a solar enamel inner tank sealing performance testing device. Background Art

[0002] In the solar water heater industry, the sealing performance of the enamel inner tank directly determines the product's service life and safety. Minor leaks may lead to thermal efficiency degradation, tank corrosion, and even system failure. Traditional sealing test devices mostly use pressure decay or bubble detection methods to determine sealing by applying air pressure or vacuum environment and monitoring pressure changes. Sealing tests can predict failures of enamel inner tanks.

[0003] Traditional sealing detection devices mainly rely on pressure decay method or bubble detection method, but such methods are difficult to achieve accurate positioning of leakage points. The detection process is highly dependent on manual visual judgment of the leakage position and subjective marking. This technical path not only causes system-level deviations in the accuracy of leak source positioning, but also causes fluctuations in detection efficiency and risks to the objectivity of the results due to the intervention of subjective experience, forming a complex technical constraint in the quality control link.

Beneficial effects

[0014] 1. The present invention, by providing an impeller and a spiral feed rod, can synchronously drive the spiral feed rod to rotate through the airflow when high-pressure gas is injected into the enameled liner body through the air inlet pipe, so that the colored fine powder in the storage barrel is accurately delivered to the interior of the enameled liner body through the spiral feed rod. When there is a small leak in the enameled liner body, the colored fine powder carried by the carrier gas will escape from the defective area in a targeted manner, forming a high-contrast color mark at the leak point. This technology upgrades the qualitative detection of the traditional pressure decay method to quantitative positioning with micron-level precision, breaking through the subjective limitations of manual visual inspection and improving the accuracy of identifying hidden defects such as micropores and cracks.

[0015] 2. The present invention is equipped with a conical anti-blocking block to prevent colored fine powder from accumulating above the impeller. At the same time, when the impeller is driven to rotate by the intake airflow, the axial thrust generated by the synchronous rotation of the spiral feed rod enables the powder conveying rate to be dynamically matched with the gas flow rate, thereby ensuring the continuity of the supply of colored fine powder and avoiding bridging blockage at the bottom of the vertical pipe, ensuring stable tracing within the test pressure range.

[0017] 4. The present invention, through the high-precision air pressure sensor at the end of the sealing tube, can realize the effect of real-time collection of internal pressure data of the enamel liner body, which is conducive to the construction of pressure monitoring of the entire life cycle of the enamel liner body; at the same time, combined with the remote transmission module, it can realize two-way data exchange between the PC and the mobile terminal, which is conducive to fault prediction of the enamel liner body.
