精密微型齒輪泵使用越來越為廣泛，那么噪音的產生也越來越多，我們對于精密微型齒輪泵降低方法時間應該如何調整呢？先來一起看以下介紹：精密微型齒輪泵主要分為：漸開線斜齒輪泵、直齒輪齒輪泵、圓弧齒輪泵、低壓齒輪泵、高壓齒輪泵、磁力齒輪泵、不銹鋼齒輪泵、鑄鋼齒輪泵、鑄鐵齒輪泵、機械密封齒輪泵、填料密封齒輪泵、銅齒輪泵、防爆齒輪泵、高真空齒輪泵等等。

Precision micro-gear pump is used more and more widely, so the noise generation is more and more. How should we adjust the time of reducing method for precision micro-gear pump? First let's look at the following introduction: precision micro gear pump is mainly divided into: involute helical gear pump, spur gear pump, arc gear pump, low pressure gear pump, high pressure gear pump, magnetic gear pump, stainless steel gear pump, cast steel gear pump, cast iron gear pump, mechanical seal gear pump, packing seal gear pump, copper gear pump. Pumps, explosion-proof gear pumps, high vacuum gear pumps and so on. 

精密微型齒輪泵降低噪音方法：

Precision micro gear pump noise reduction methods:

精密微型齒輪泵噪聲重要是氣體/液體在輸送過程中產生的空氣動力噪聲，電機機殼受振動激發的結構噪聲，機座因振動產生的噪聲，以及電動機的噪聲。此類噪聲級峰值重要集中在低倍頻帶，大約在100-450Hz的范圍內。該聲源在齒輪泵泵房正常運行時屬于穩態噪聲。管道噪聲是指介質在管道中流動時所產生的噪聲。另外，齒輪泵的氣蝕征象及停泵水錘征象也能夠產生瞬時噪聲。給水管道產生的噪聲，受流速和壓力影響。

The noise of precision micro gear pump is mainly the aerodynamic noise produced by gas/liquid in the process of transportation, the structural noise caused by the vibration of motor housing, the noise caused by the vibration of machine seat and the noise of motor. The peak value of such noise level is mainly concentrated in the low frequency doubling band, which is in the range of 100-450Hz. The sound source belongs to steady-state noise when gear pump room is in normal operation. Pipeline noise refers to the noise produced by the medium flowing in the pipe. In addition, the cavitation signs and water hammer signs of gear pump can also produce instantaneous noise. Noise generated by water supply pipeline is affected by flow rate and pressure.

精密微型齒輪泵房整套設施產生的噪聲重要為機械噪聲，目前聲學原理上治理噪音的方法較常使用的是控制噪聲的傳播途徑，重要有隔聲、吸聲、消聲等。隔聲是行使隔聲結構將聲源與受聲點隔開；吸聲是行使吸聲結構或吸聲材料降低噪聲；消聲是行使阻抗、抗性、多孔擴散等原理，降低噪聲量值。

The noise produced by the whole set of facilities of precision micro gear pump house is mainly mechanical noise. Nowadays, the method of noise control in acoustics principle is often used to control the transmission of noise, and the important ones are sound insulation, sound absorption and noise elimination. Sound insulation is to separate sound source from sound receiving point by using sound insulation structure; sound absorption is to reduce noise by using sound absorption structure or sound absorbing material; noise elimination is to reduce noise value by using the principles of impedance, resistance and porous diffusion.

噪聲控制措施應根據聲學原理，盡量充分行使場地環境和條件。如：1、根據泵房環境，將聲源封閉不精密的泵房進行隔音處理，將泵房產生噪聲的房間采取吸聲/隔聲處理，門窗也要做隔音處理等。2、控制機器設備和設備零件產生的噪聲。新建泵房水泵基礎宜采用重量大的，防止振動產生噪聲。而且應設橡膠隔振墊等進行隔振，從而削減振動的噪聲；每個水泵機組單獨設置基礎，防止產生共振。在水泵吸、壓水管上盡可能的采用“軟性”聯結。定期檢修，發生題目如盤根漏水、設備零件松動，設備零件磨損緊張、機械振動等應及時維修，從而削減噪聲。

The noise control measures should be based on the acoustic principle and make full use of the site environment and conditions. For example: 1. According to the environment of the pump room, the inaccurate pump room with closed sound source is treated with sound insulation, the room with noise in the pump house is treated with sound absorption/sound insulation, and the doors and windows are also treated with sound insulation. 2. Controlling the noise produced by machinery and equipment parts. The pump foundation of a new pump house should be heavy in weight to prevent vibration and noise. In addition, rubber vibration isolation pads should be installed to isolate vibration, so as to reduce the noise of vibration; each pump unit should set a separate foundation to prevent resonance. As far as possible, "soft" connection should be used in pump suction and pressure pipes. Regular maintenance, such as root leakage, loosening of equipment parts, wear and tear of equipment parts, mechanical vibration, etc. should be maintained in time to reduce noise.

在此，提醒大家的一點是，我們針對不同廠家和類型的精密微型齒輪泵，工作原理和結構都會有差異，所以，對噪聲源進行現場勘測和分析對泵房隔音降噪方案的設計和材料的選擇都十分緊張。

Here, it is a reminder that we have different working principles and structures for different manufacturers and types of precision micro-gear pumps. Therefore, on-site investigation and analysis of noise sources are very tense for the design of sound insulation and noise reduction scheme and the selection of materials for pump room.
