Description

Nuclear island filter test device

Technical Field

The existing nuclear island filter test device adopts a pipeline connection mode, and the pipeline material is usually metal or UPVC. Whether metal pipeline welding or UPVC pipeline bonding, the test bed of the filter is fixed, and is inconvenient to modify and disassemble, so that the nuclear island filter test device is only suitable for one performance test such as a flow differential pressure test. When another performance test is required, the nuclear island filter test equipment needs to be reconfigured, which increases the test cost.

Specifically, the existing nuclear island filter test device has the defects that:

(1) The pipelines of the test device are welded or bonded, the bench is required to be modified when a problem is encountered in the test, the modification workload is large, and the time consumption is long;

(2) Different types of tests (flow differential pressure tests, anti-extrusion tests, filtration accuracy tests, etc.) require different test benches (single test benches are large in retrofitting work); the bench retrofit effort for the same type of tests with different sized filters (3 ", 4", 6", 8", 12", 16") is also relatively large.
