    2020-1-1 · They found that for a subsonic low-speed jet, the noise intensity scales with 5th power of the jet speed, suggesting that instead of the jet mixing noise, the slot-blowing noise was the main contributor to the overall self-noise of the air curtain, i.e. classic lip noise , , . This lip noise became greater when the jet speed increased to 90 m/s ...

  • Getting to the root of hydraulic noise problems ...

    2019-8-21 · This design is more efficient than a large conventional accumulator because the fluid flow-path to the bladder is short and unrestricted, and the fluid contacts a much greater bladder area. Conclusion. To reduce noise in a power unit: * select an appropriate pump with a low noise-level rating

  • Use of a multiplexed oscillator in a miniaturized ...

    2008-4-14 · In the design of multiplexed oscillator the on/off resistance values (R on, R off) of the analog switches are important parameters. In particular according to (2) if R on increases the Q factor decreases, because it adds to the quartz motional resistance (R s). On the other side if a not very large value of R off is used the oscillation could ...

  • Specification for low cross section seals | SKF

    G design radial shaft seals. G design radial shaft seals are made of acrylonitrile-butadiene rubber (NBR). The seals for shaft diameters ≥ 8 mm are reinforced with sheet steel.The rubber outside diameter enhances the seal around the housing bore and reduces the risk of damage to the seal and housing during installation and removal.
