Suction of 80% of the discharge air! OKE-MB01FJ suction measurement.

We investigated the performance of a loop flow microbubble generation nozzle. The self-priming capacity of standard and semi-standard nozzles was measured in increments from 0.00 to 0.01 MPa. The experimental results yielded unexpectedly very interesting findings, revealing the existence of a water pressure at which the self-priming capacity becomes discontinuous. 【Experimental Conditions】 - Water temperature heater: set to 43°C. Using tap water pressure → Pressure measured at the base of the shower hose → The MB generation nozzle was installed at the tip of the shower hose, with nothing attached to the nozzle tip - The self-priming inlet was fully opened with a throttle valve - Used two 6 mm outer diameter tubes - A check valve with a cracking pressure close to 0 was used in between - Self-priming capacity measuring device → Horiba Seiki digital flow meter SEF-51 - Nozzle used: OKE-MB01FJ, discharge capacity of 7L/min (at water pressure of 0.15 MPa) 【Results and Discussion】 - The self-priming capacity was very high, accounting for 80% of the discharge capacity - At a water pressure of 0.15 MPa, the self-priming capacity was 5.6 L/min → Beyond this pressure, it jumped to 0.18 MPa, and the self-priming capacity drastically decreased to 3.6 L/min - There exists a water pressure at which the self-priming capacity becomes discontinuous → In the case of OKE-MB01FJ, this water pressure is 0.15 MPa For more details, please contact us or refer to the catalog.
