The high-pressure reactor has the characteristics of static sealing, no leakage, no noise, no pollution, stable operation, simple operation, sturdy and durable, compact structure, etc., so that it can be used in high temperature, high pressure, high vacuum, high speed, suspension, and convection state.
High-pressure reactor vessels can maintain environments of 3,000 PSI and 500 degrees. Vessels rated for higher pressures require thicker walls, though, making temperature control more difficult. The manufacturer's limits must be maintained during operation, as the gases are highly reactive, as well as the high pressure being a hazard itself.
1) Turbulence noise. Turbulence noise is generated by the interactions between the turbulent fluid and the pressure relief valve or pipe surface. Its frequency and noise level are relatively low, which generally does not constitute a noise problem. If it does become a noise issue, you may need to rearrange the pipeline more efficiently.

The term ‘water hammer’ is used to describe that loud banging noise when highly pressure water encounters a valve. Changes in water pressure can cause your house’s plumbing to creak and groan, and this can be a very disruptive experience. Low and high water pressure are different problems with different root causes.

May 01, 2018 · Cross-sectional area distribution of broadband noise in a sonochemical reactor was measured to estimate reaction fields. At 130 kHz, sonochemical reaction fields were observed in several ellipsoidal shapes. The reaction fields were high in the upper part of the reactor and weak at the pressure antinodes of the fundamental frequency.
Dec 31, 2011 · Sources of noise. A hydraulic system's greatest contributor to noise is the power unit, Figure 1. Noise not only emanates directly from the electric motor and pump, but also is caused by pressure fluctuations in the hydraulic fluid and by components — either resulting from these pressure fluctuations or from physical vibration.
Nov 07, 2015 · The high pressure pump takes gas from the tank and boosts it to 2,000-psi. The high pressure pump runs off a 3-lobe portion of the camshaft.
