High-temperature resistant hydraulic pump
Thread Content
Dear experts, I am currently conducting nozzle tests and need a pressure oil source in order to study the physical and chemical properties of the nozzles under different temperature and pressure conditions. The pressure range required is from 0.2 MPa to 3 MPa (with a precision requirement of 0.001 MPa), and the temperature range is from -50°C to 160°C. However, the temperature tolerance of volume pumps commonly used in industry is not this wide, and such pumps also exhibit pressure fluctuations at the outlet, making it difficult to ensure accurate pressure control. Are there any experts with experience in this area? Looking for recommendations! ! ! :handshake:handshake:handshake
The plunger pumps that are available generally do not have such a wide temperature tolerance range. Moreover, the project requires a high level of pressure accuracy (0.001 MPa), and the flow rate can vary significantly – with the minimum and maximum flow rates being nearly in a 1:100 ratio. It is therefore necessary to consider flow rate segmentation: for a flow rate ratio of 1:10, a pump with a lower flow rate should be used, along with variable frequency speed control； Choose a pump with a higher flow rate for the flow range of (10:100)
