Aeration and cavitation reduction device for hydraulic machinery
The invention relates to the technical field of aeration and cavitation reduction, and discloses a hydraulic machinery aeration and cavitation reduction device which comprises an aeration assembly and an air source, the aeration assembly comprises at least one set of spray heads communicated with the interior of a pipeline of a hydraulic machinery, and spray needles capable of moving in the airflow direction and conical nozzles are arranged in the spray heads; a conical part inserted into the nozzle is arranged on the spray needle, so that the effective air outlet area of the nozzle is adjusted through movement of the spray needle; the gas source is communicated with a spray head in the aeration assembly through a pipeline provided with an electronic metering control valve, and is used for providing gas flow with adjustable flow and stable output; in the hydraulic machinery air entrainment and corrosion reduction device, as the air source can provide air flow with stable flow through the electronic metering control valve, the flow velocity of the air flow can be adjusted by adjusting the effective contact area of the nozzle and the water flow in the pipeline under the condition that the flow is not changed; therefore, the phenomenon that the airflow cannot be injected into the water flow or even countercurrent is generated due to insufficient airflow velocity can be solved.
本发明涉及掺气减蚀技术领域，公开了一种水力机械掺气减蚀装置，包括掺气组件及气源，其中，掺气组件包括至少一组与水力机械的管路内部连通的喷头，喷头内部设有可沿气流方向移动的喷针及锥形的喷口，喷针上设有插入喷口中的锥形部，以通过喷针的移动调节喷口有效出气面积；气源通过设有电子计量控制阀的管道与掺气组件内的喷头连通，用以提供流量大小可调且输出稳定的气流；本发明的水力机械掺气减蚀装置内，由于气源通过电子计量控制阀可提供流量稳定的气流，在流量不变的情况下，通过调整喷口与管路内水流接触的有效面积，可调整气流的流速，进而可解决因气流流速不足导致的无法将气流射入水流内部甚至产生逆流的现象。
