Application of load sensitive variable pump in offshore drilling platform
Load sensitive variable pumps can control the pressure and flow rate of pump output according to load requirements,and can stay in standby mode when there is no load.With advantages such as energy saving,high efficiency,and long service life,they are widely used in offshore drilling platform equipment,such as cranes and JJC hydraulic stations.Taking the offshore platform crane's Rexroth A10 load sensitive axial piston variable pump as an example,this paper introduces the composition structure and manifold block function of the variable pump,and analyzes the working principle and adjustment method of the piston pump.Then,AMEsim hydraulic simulation software is used for load sensitive variable pump modeling and simulation.At last,common faults of offshore cranes,including no pressure in the hydraulic operation control system,crane failure,slow operation of the crane's main hook,and load lifting failure of the auxiliary or main hook,are analyzed and verified and resolutions are given.
