- Summary:
- The working principle and performance test method of the gerotor pump with multi-arc combined profile are introduced. According to the formation method of the rotor tooth profile, the calculation method of the inner rotor tooth profile is introduced, and the meshing characteristics of the inner and outer rotors are analyzed. On this basis, a calculation method for the displacement and instantaneous flow rate of the gerotor pump with multi-arc combined profile is proposed. In addition, a calculation model of the flow field characteristics of the gerotor pump with multi-arc combined profile is established, and the validity of the model is verified by experiments. Based on the model of traditional single-arc gerotor pump and the model of the gerotor pump with multi-arc combined profile, the flow rate, internal flow velocity, pressure distribution and gas volume fraction distribution under different working conditions are calculated respectively. The results show that: compared with the single-arc gerotor pump, the maximum flow velocity and gas volume fraction inside the multi-arc gerotor pump are lower, while the minimum pressure is higher. Besides, the influence of design parameters on the flow field characteristics is evaluated. The method and model proposed in this paper can effectively characterize the flow field characteristics of the gerotor pump with multi-arc combined profile and provide data support for its structural design
