In order to improve the capabilities of the pump in the Vacuum Oil Purifier used in the power plant, researched the principle of the reciprocating pump and the rotary pump, and combined their advantages and structures. A new reciprocating-rotary pump was designed by using the crank-turn mechanism. After analyzed and calculated, a model machine was designed by operational requirements. Under the given conditions, and referenced to “Mobile Reciprocating Pump Test Method” the capability test of the pump was carried out. According to the results of the test, the difference between actual and theory oil amount was only 5.0%. The new reciprocating-rotary pump not only met the design requirements, but also had features of high volumetric efficiency, large exclusive, low flow pulse and good seal.
