Background
Currently, a pressure test is performed on shells of CDM3 and other series products, the pressure bearing capacity of the cover body is checked, and whether the cover body can bear the impact force when the product is broken or not is deduced. The test method for the surface cover and the middle cover comprises the steps of sequentially closing and horizontally placing the whole cover body base, the middle cover and the surface cover, applying pressure from the surface of the cover body to the inside by using a corresponding pressure head on the universal machine until the cover body is perforated, as shown in fig. 7, but the operation is insufficient:
