Convenient pump acoustic performance acquiring method based on functional parameters

The invention provides a convenient pump acoustic performance acquiring method based on functional parameters. The method comprises the following steps that a passive parameter matrix T is calculatedbased on the pump flow, the lift and the geometric structure size; a pump inlet/outlet acoustic state parameter matrix U is acquired; and on the basis of the relation among the passive parameter matrix T and the pump inlet/outlet acoustic state parameter matrix U as well as a pump acoustic performance parameter S, the pump acoustic performance parameter S is acquired. According to the method, a complex acoustic testing process can be avoided, meanwhile, all pump acoustic performance information can be acquired while the influence of a test bed is avoided. 本发明提供一种基于功能参数的便捷式泵声学性能获取方法，包括如下步骤：基于泵流量、扬程以及几何结构尺寸，计算被动参数矩阵T；获取泵进/出口声学状态参数矩阵U；基于被动参数矩阵T、泵进/出口声学状态参数矩阵U与泵声学性能参数之S间的关系，获取泵声学性能参数S。该方法既可以避免复杂的声学测试过程，同时又能在避免试验台架影响的同时，获取全部的泵声学性能信息。
