Inner container straight seam leakage detection assembly, inner container leakage detection system and leakage detection method

Abstract

The invention discloses an inner container straight seam leakage detection assembly, an inner container leakage detection system and a leakage detection method. The inner container straight seam leakdetection assembly comprises a vacuum pumping module used for carrying out vacuum pumping processing of an inner container, a gas storage module which stores nitrogen and hydrogen gas and is used forcharging the nitrogen and hydrogen gas into the inner container, a detection module which is provided with a detection head and is used for carrying out hydrogen detection on the linear weld joint ofthe inner container, and a driving module which is used for driving the detection head to move along the linear weld joint of the inner container and bypass a hanging frame on the inner container. Themethod 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 areimproved.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to an inner tank straight seam leak detection component, an inner tank leak detection system and a leak detection method. 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 circular welds and linear 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 follo...

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.
