Noise pollution, because most people nowadays know of, is the production of undesirable sounds that leave adverse effects on the tender ears and so pose potential hazards to health and communicating. Thinking about the serious health hazards of noise pollution, many nations have introduced regulations to restrict the sound levels at workplace.
In frekvenčni regulatorji hydraulic systems, normally, a pump would be your source of noise pollution that calls for particular attention to fight the matter. Every hydraulic pump injects fluid and structure borne noise within the system and consequently renders air-borne sound out in the surroundings. Here, it’s very important to see that fluid-related sound is generated due to the vibration of components by pressure pulsations while structure-related sound is the result of exciting vibrations within the interlinked components. The fluid and structure noises together infect the involved air mass consequently, polluting the environment.
Following are a few key solutions to three fundamental resources of hydraulic system’s noise emission:
Fluid-borne sound : This sort of noise in a hydraulic system can always be lessened through a better pump layout but yet, it cannot be diluted completely. Setup of a silencer can prove helpful in restraining the pump sound. A very simple reflection silencer reduces the sound waves by superimposing another noise wave carrying same amplitude and frequency at a 180 degree phase angle into the original one.
Structure-borne noise: The trick to tackle structure noise is to eliminate the noise bridges amongst electricity unit and tank and electricity unit and valves as the sound is generated due to the vibrations of power unit and its prime movers. Rubber mounting blocks and elastic hoses as relations can come handy in this circumstance. Alternately, introduction of an additional mass may also help in reducing the vibrations in bridging points.
Air-borne noise :Such noise could be managed by lifting the pump inside the tank or constructing the hydraulic reservoir using a thicker plate to decrease the sound radiations. The easy scientific reason for it is the size of noise radiations via a specified item is directly proportional to its area and inversely proportionate to its own mass hence, an increase in bulk of an object or a reduction in its surface area can prove successful in controlling the sound radiations.
