7results about How to "Adjust flow" patented technology

A non-submerged cavitation-erosion synergistic damage simulation device, system and method belong to the field of hydraulic machinery working condition simulation, including a sediment jet channel and a cleaning fluid channel in its periphery; high-speed sand-containing fluid is introduced into the sediment jet channel to form a central high-speed jet impacting the sample surface, high-speed cleaning fluid is introduced into the cleaning fluid channel to form a peripheral low-speed water curtain surrounding the central high-speed jet after being ejected from the annular steady flow pipe, and the peripheral low-speed water curtain impacts the sample surface to form a local liquid phase confining pressure zone together with the central high-speed jet. The present application not only realizes the true simulation of the actual working condition under non-submerged conditions, but also can adjust the flow and pressure of the cleaning fluid to adjust the cavitation number and cavitation collapse intensity around the high-speed sand-containing jet without changing the atmospheric environmental pressure, and quickly adjust the simulation test parameters.

This invention belongs to the technical field of hydraulic component testing and discloses a deep-sea steady-state performance testing system and method for electromagnetic directional valves. The testing system includes a pressure cylinder, an electromagnetic directional valve, a pressure compensation unit, and a testing unit. The electromagnetic directional valve is housed in the pressure cylinder, which provides simulated pressure at full ocean depth. The pressure compensation unit is connected to the electromagnetic directional valve to compensate for the full-ocean-depth pressure, thus enabling the electromagnetic directional valve to operate at its rated voltage. The testing unit is connected to the electromagnetic directional valve to test the performance of its inlet and outlet ends. The testing unit includes a throttle valve connected to the outlet end of the electromagnetic directional valve to simulate its load. This invention also discloses a testing method for the above-mentioned testing system. This invention solves the problem of the inability to perform full-ocean-depth steady-state performance testing of electromagnetic directional valves.
