【Abstract】 In this paper, the operation principle of electric proportional variable-volume pump is introduced, and the property of proportional electromagnetic valve is discussed also. In order to have the more proper application of constant power variable- volume pump in hydraulic system of drilling rig, the performance test of its proportional electromagnetic valve has carried out, and tested results indicate that the electric proportional variable-volume pump can be successfully used to the hydraulic system of drilling rig.更多还原
