Abstract
The subject of this paper is the super windlass of φ130mm diameter anchor chain. And this paper focuses on the study of hydraulic plunger pump of water hydraulic control system.The water axial piston pump is designed to meet the requirements by the design method of theory. Through the analysis, the kinematics characteristics, dynamic characteristics and match flow characteristics are studied. And optimization structure basis is proposed. The major research contents of this paper are as follows.
1. The design of water axial piston pump is studied. Design method of the key parts is proposed. According to the operational requirements of pure water hydraulic control system of the super windlass of φ130 mm diameter anchor chain, MATLAB program method is used to calculate the main structural parameters of the water axial piston pump.
2. 3D modeling software PRO/E is used to respectively establish geometric model of pure water axial piston pump and its corresponding flow field. In the process of geometry modeling of the piston pump, process of the piston pump shell and support is simplified and omit, considering the main research is the piston pump kinematics characteristics; In the process of modeling the flow field, oil film influence on the complexity of the modeling analysis is considered. Under the premise of model has no influence on analysis results, process of the flow field is simplified and ignored.
3. ADAMS is used to establish physical model of the pure water hydraulic plunger pump. Its rigid body model is established and its kinematics characteristic is analyzed. Its key parts are flexibly processed. Ally of ADAMS and ANSYS is used to solve the analysis and simulation of rigid-flexible dynamic characteristics of multi-body system. The dynamics characteristics are analyzed. The kinematics characteristics and dynamic characteristics of key parts can verify the rationality of the design.
4. The flow characteristic of the water axial piston pump is analyzed. Law of flow field of water axial piston pump is analyzed by using the technology of CFD. After rule of the flow field is get, such as the pressure, turbulent kinetic energy. Structure of the valve plate is optimized, flow characteristics of the piston pump and the work performance are improved.
