Leakage testing device and leakage checking method

Abstract

The invention provides leakage testing equipment. The leakage testing equipment comprises a platform, a vertical frame mechanism and a floating mechanism; the floating mechanism is arranged in a detection space and comprises a floating body, an air inlet and an overflow port; the platform is provided with a liquid port communicated to the detection space; the leakage testing equipment further comprises a gas supply pipeline, an overflow pipeline and a waterway; the gas supply pipeline is provided with a gas pipe valve and an airtight monitor, and the overflow pipeline is provided with a first valve and a liquid level sensor; the water path is provided with a liquid inlet branch and a liquid pumping branch so as to feed or discharge water in or out of a sealed space; and the floating body can follow up and float to abut against the bottom of the box body after water enters the floating body, water higher than the overflow opening can overflow to the outside along the overflow pipeline through the overflow opening, and the air inlet is kept to be externally arranged on the liquid level. Water is directly fed into or discharged out of the box body through a water path, and the effect is particularly remarkable. The operability and the convenience of leak detection are greatly improved, and the production efficiency and the quality of finished box bodies are improved. The invention further provides a leak checking method.

Description

technical field [0001] The invention relates to the technical field of air tightness detection, in particular to a leak testing device and a leak testing method. Background technique [0002] With the rapid development of my country's economy and the continuous increase in power demand, transformers, as the main equipment in power transmission and transformation systems, have also achieved long-term development. [0003] In the whole set of transformer equipment, the sealing of the box is particularly important. At present, the box body has always been manually placed on the ground with its opening facing up and placed flat, and water is manually injected from the opening to test the tightness and leak point. Although such a test method is relatively simple to operate, misjudgment of the leak point often occurs, and it is difficult to effectively and accurately determine the specific location to be repaired. In particular, after the test is completed, the drainage is manua...

AI Technical Summary

Problems solved by technology

Although such a test method is relatively simple to operate, it often leads to misjudgment of leak points, and it is difficult to accurately determine the specific location to be repaired.

In particular, after the test, the drainage is manually operated, which is more difficult to operate, resulting in low efficiency, waste of resources, difficult operation, etc., which is not conducive to batch detection operations
