Problems solved by technology

[0003] Due to the complex structure of the distribution plate window, the traditional method needs to analyze the distribution area when the pump rotates to different positions through the segmental analysis method. The calculation is more complicated, which is not conducive to rapid optimization and iterative design of the ideal distribution window and the shape of the cylinder end surface window. structure, which affects product design efficiency and quality

Embodiment Construction

[0018] A parameterized agile calculation method for the flow distribution area of ​​a plunger pump, which improves the traditional segmental analytical calculation method for the flow distribution area. The specific calculation process is as follows: figure 2 shown.

[0019] Step 1: Extract and parameterize the structural design parameters of the distribution plate window and the cylinder end surface window, including the width and opening angle of the distribution window, the width and opening angle of the pressure relief groove, the width and opening angle of the cylinder end surface window, The meaning of each parameter is as figure 1 ;

[0020] Step 2: Analyze and describe the structural shape of the flow distribution window with the pressure relief groove structure and the cylinder end surface window with a piecewise function to accurately reflect the actual structure. Among them, the common waist-shaped distribution window and the cylinder end surface window structure ...

Abstract

The invention puts forward a parameterized agile computation method for a plunger pump flow distribution area, and belongs to the design technology of hydraulic pumps. A discretized and simple intersection thought is adopted to solve the flow distribution area into simple and repeated calculation. The parameterized agile computation method is adopted, any flow distribution disk and the window parameter of a cylinder are changed after implementation is carried out through programming, the computation result of the flow distribution area can be computed by one key and can be taken as the input for subsequent plunger pump flow distribution performance analysis, and convenience is brought to the quick iterative design of the flow distribution design.

Description

technical field [0001] The invention belongs to hydraulic pump design technology, and in particular relates to a parameterized agile calculation method for the flow distribution area of ​​a plunger pump. Background technique [0002] Flow distribution design is one of the key technologies of plunger pump design. It is mainly through the design of the shape of the flow distribution window on the distribution plate, the opening angle, the structure of the unloading groove and the structure of the window on the end face of the cylinder, so as to ensure that the plunger pump can normally suck in and discharge in accordance with The hydraulic oil required by the flow rate does not introduce significant pressure, flow shock and pulsation. When analyzing pressure, flow and its pulsation impact, it is necessary to know the change law of the flow distribution area as the pump rotates. The flow distribution area refers to the intersection area between the flow distribution window and ...
