[0002] With the continuous advancement of technology, the requirements for BOP performance are increasing day by day. Traditional spraying methods can no longer meet the needs. For example, simple fixed nozzle spraying cannot cover all parts of the BOP, which may lead to inaccurate test results. The instability of spraying pressure and flow will also affect the evaluation of key indicators such as the sealing performance of the BOP. In the manufacturing of heavy machinery, the precision and quality of parts processing directly affect the performance and reliability of the entire machinery. Similarly, the effective operation of the spray mechanism of the BOP test machine also depends on the high-precision processing of its internal parts.

[0003] The existing spray mechanism of the blowout preventer test machine may not be able to perform a large-area coverage spray test on the blowout preventer test machine, which may lead to deviation in the evaluation of the blowout preventer performance. Therefore, we propose a spray mechanism for the blowout preventer test machine. Utility Model Content
