對于廚房設備噪音大的問題，很多朋友不知該如何解決，那么今天小編就來為大家介紹一下降低廚房設備源噪聲的方法。
For the central kitchen equipment noise problem, many friends do not know how to solve, so today Xiaobian will introduce the method to reduce the central kitchen equipment source noise.
合理選擇透風設備的機型。在噪聲控制要求高的場合，應選用低噪聲透風設備。不同型號的透風設備在同意的風量、風壓下、機翼型葉片的離心透風設備噪聲小，前向版型葉片的離心透風設備噪聲大。
Reasonable selection of ventilation equipment model. Low noise ventilating equipment should be selected in the occasion with high noise control requirements. Under the agreed air volume and pressure, the noise of centrifugal ventilation equipment with wing blade is small, while that of centrifugal ventilation equipment with forward blade is large.
在可能前提下適當降低透風設備的轉速。透風廚房設備的旋轉噪聲與葉輪圓周速度10次方成比例，渦流噪聲與葉輪圓周速度6次方(或5次方)成比例。故降低轉速可降低噪聲。
If possible, reduce the speed of ventilation equipment. The rotating noise of ventilation central kitchen equipment is proportional to the 10th power of impeller circumferential speed, and the eddy current noise is proportional to the 6th power (or 5th power) of impeller circumferential speed. Therefore, reducing the speed can reduce the noise.
透風設備進、出口的噪聲級是透風理、風壓曾加而變大。因此，設計透風系統(tǒng)時，應盡量減少系統(tǒng)的壓力損失。當透風系統(tǒng)的總量和壓力損失較大時，可將其分為小系統(tǒng)。
The noise level at the inlet and outlet of ventilation equipment increases with the increase of ventilation principle and wind pressure. Therefore, the pressure loss of ventilation system should be reduced as much as possible. When the total amount and pressure loss of ventilation system are large, it can be divided into small systems.
透風設備的工作點應接近效率率點。統(tǒng)一型號的廚房設備的透風設備效率越高，噪聲越小。為使透風設備的運行工況點保持在透風設備的效率率區(qū)，應盡量避免用閥門進行工況調節(jié)。如需要在透風設備壓出端設閥門時，其設置的位置是距透風設備出口1m處。它能使2000Hz以下的噪聲降低。在透風設備進口處氣流應保持平均。
The working point of ventilation equipment should be close to the efficiency point. The higher the ventilation efficiency, the lower the noise. In order to keep the operating point of ventilating equipment in the efficiency area of ventilating equipment, the valve should be avoided as far as possible. If it is necessary to set a valve at the pressing end of the ventilating equipment, the setting position is 1m away from the outlet of the ventilating equipment. It can reduce the noise below 2000 Hz. The air flow at the inlet of ventilating equipment shall be kept even.
留意透風設備與電念頭的傳動方式。采用直聯(lián)傳動的透風設備噪聲小，用聯(lián)軸器的次之，用沒有接縫的三角皮帶傳動的稍差。透風設備應配用低噪聲的電念頭。
Pay attention to the transmission mode of ventilation equipment and motor. The ventilation equipment with direct drive has less noise than that with coupling, and that with V-belt without seam is slightly worse. Ventilating equipment shall be equipped with low noise motor.
氣流在管道內(nèi)的流速不宜過高，以免引起再·生噪聲。確定管道內(nèi)氣流流速應根據(jù)不同要求按有關劃定選取。
The velocity of air flow in the pipe should not be too high, so as to avoid causing noise again. The velocity of air flow in the pipe should be determined according to different requirements.
