However, when customers purchase sealing rings, they usually only check the appearance and size, and cannot conduct random inspections on the sealing performance of the sealing rings. Therefore, the existing pressure test is performed on the product body. If the pressure test is performed after assembly When it is found that the sealing ring fails, it needs to be disassembled again, wasting time and cost
For the sealing rings used in production, for example, after the maintenance of the main pump, because it is impossible to judge whether the sealing ring can still play a sealing role, it is often replaced with a new sealing ring directly, resulting in an increase in cost, and if the new sealing ring is not replaced, the It is impossible to judge whether it can play a sealing effect

Abstract
The invention relates to an O-shaped ring hydrostatic test device for a nuclear main pump, and the device comprises a pressing mold and a pressure gauge, the pressing mold comprises an upper mold and a lower mold, the upper mold comprises a first main body provided with a first cavity and a first upper end part and a first lower end part which are oppositely arranged, and the first upper end part is communicated with the pressure gauge; the lower die comprises a second main body which is provided with a second cavity and is provided with a second upper end part and a second lower end part which are oppositely arranged, the second upper end part is provided with a second flange plate and a second containing boss, the second lower end part is used for being communicated with a pressure supply device, and the first cavity is communicated with the second cavity; an O-shaped ring to be detected is placed between the first containing boss and the second containing boss, and the first flange plate and the second flange plate are connected through a fastener so that the end face of the first containing boss can be tightly attached to the end face of the second containing boss. The pressure-resistant performance of the O-shaped ring can be detected in different test environments, the use is convenient, and the test is accurate.
Description
technical field [0001] The present disclosure relates to the technical field of production and testing of nuclear power products, in particular, to an O-ring hydraulic test device for nuclear main pumps. Background technique [0002] The sealing ring used in the main pump of nuclear power has high requirements for pressure resistance. Before use, it is necessary to ensure that the sealing ring can meet the use of the product. After use, it is necessary to judge whether the sealing ring can still meet the pressure resistance requirements of the power station. In addition, due to the strict performance requirements of the sealing ring on the nuclear power main pump in various harsh environments, it is necessary to meet the pressure resistance performance test requirements in different medium environments. However, when customers purchase sealing rings, they usually only check the appearance and size, and cannot conduct random inspections on the sealing performance of the seali...
