Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pressure maintenance, in particular to a storage pressure maintenance bin used for sealing testing of a water making machine. Background Art

[0002] During the production and manufacturing process of the water making machine, the condenser is one of the core components, and its sealing performance and pressure resistance directly affect the stability and safety of the entire system. In order to ensure that these key indicators meet the design and use standards, manufacturers usually conduct a vacuum pressure test after the condenser is welded. This test is to vacuum the condenser and then maintain the pressure stable for a certain period of time to detect whether there are leaks or defects. This process usually involves manually filling the condenser with high-purity nitrogen to simulate the working pressure. Then, manual participation is required to move the semi-finished water making machine after nitrogen filling to the vacuum pressure chamber for pressure testing. Multiple transportations require frequent opening and closing of the door of the pressure chamber, which is prone to pressure fluctuations and leaks, which may ultimately affect the accuracy of the vacuum pressure test of the water making machine.
