Inner container straight seam leak detection method

Abstract

The invention discloses an inner container straight seam leakage detection method. The inner container straight seam leakage detection method comprises steps that nitrogen and hydrogen gas is filled into an inner container through a water inlet and outlet pipe of the inner container, and a hydrogen detector moves along a straight seam on the inner container to carry out hydrogen detection. The method is advantaged in that automatic leakage detection of the inner container is achieved, labor cost and labor intensity of workers are reduced, and leakage detection efficiency and precision are improved.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a leak detection method for straight seams of inner tanks. Background technique [0002] At present, water heaters are commonly used electrical appliances in people's daily life. The inner tank in the water heater is processed by welding (generally including straight-line welds and straight-line welds), and the inner tank is welded with water inlet and outlet pipes (water inlet and outlet pipes). Water pipe), at the same time, in order to install the electric heating tube and magnesium rod, the inner tank is welded with a corresponding installation nozzle to install the electric heating tube and magnesium rod. Therefore, after the inner tank is assembled, it is necessary to perform leak detection on the weld seam of the inner tank and related assembly parts. In the prior art, the leak detection method of the water heater liner is as follows: seal the assembled liner and fill it with hi...

Problems solved by technology

However, in the production process of the factory, the workers detect the air leakage of the liner in the water tank. On the one hand, the detection efficiency and accuracy are low, and on the other hand, the labor cost increases and the labor intensity of the workers is relatively high.
