Therefore, in order to meet the requirements of reducing noise of hydraulic oil source testing equipment, an integrated sound insulation and noise reduction structure is adopted to make the hydraulic oil source equipment, so that the equipment itself has sound insulation and noise reduction functions, which is convenient for users to install. The equipment can be used independently as a single set, or multiple devices can be used in parallel to meet the user's usage needs.
