Description

Technical Field

[0001] This utility model relates to the technical field of water pump noise testing, and in particular to a water circuit construction facility for water pump noise testing. Background Technology

[0002] The noise problem of automotive electronic water pumps has significant unique characteristics and harmful effects. Unlike ordinary industrial water pumps, their operating environment is compact and more sensitive to noise—the cockpit, as a relatively enclosed space, allows water pump noise to be easily transmitted and amplified through the vehicle structure, directly affecting the comfort of passengers. Especially in new energy vehicles, where the masking effect of the traditional engine is eliminated, the noise of electronic water pumps is more easily highlighted, becoming a significant factor affecting the overall NVH (noise, vibration, and harshness) performance of the vehicle. Prolonged exposure to such a noisy environment can not only cause discomfort such as irritability and fatigue for passengers, but may also distract them, indirectly affecting driving safety. As consumers' demands for the automotive driving experience continue to rise, and as the automotive industry's NVH performance standards become increasingly stringent, noise control of automotive electronic water pumps has become a crucial aspect for automakers to enhance product competitiveness. Existing testing equipment is insufficient to meet the needs of refined R&D and quality control of automotive electronic water pumps in terms of simulating the actual operating environment of a vehicle, eliminating complex electromagnetic interference, and achieving multi-parameter linkage testing and spectrum analysis. Therefore, developing a noise testing device for automotive electronic water pumps that can accurately simulate the automotive working environment, effectively isolate internal and external interference, and achieve multi-dimensional analysis of noise characteristics under all working conditions is of great significance for improving product performance and meeting market demands.

[0003] For example, in a prior art represented by application number CN202122554903.2, the main structure includes a water storage tank connected to an inlet pipe and multiple outlet pipes of different diameters. The inlet pipe is connected to the inlet of the water pump under test, and one of the outlet pipes can be selectively connected to the outlet of the water pump under test. A soundproof chamber is also included to house the water pump under test, and a signal acquisition system for noise detection is installed inside the soundproof chamber. This water pump noise testing system, by setting multiple outlet pipes of different diameters, allows for the selection of the required outlet pipe diameter when testing water pumps with different flow rates and power. This avoids a large difference between the outlet pipe diameter and the diameter of the water pump under test, thereby shortening the venting time, ensuring complete gas removal, preventing cavitation, and improving the accuracy of the test results.

[0004] During use, it was found that the existing water circuit setup for testing water pump noise is relatively slow and has low testing efficiency. Therefore, there is an urgent need for a water circuit setup for testing water pump noise. Utility Model Content
