【Abstract】 Based on the failure analysis of the fracturing pump valve chamber , a model for calculating its reliability under three-dimensional stress is established,and a computing program is worked out. As an example,the failure probability and design reliability of the valve chamber on Model YLB-1000 fracturing pump are analyzed,and the critical points are indicated. The calculated results are consistent with field investigation.更多还原
