精密微型齿轮泵使用越来越为广泛，那么噪音的产生也越来越多，我们对于精密微型齿轮泵降低方法时间应该如何调整呢？先来一起看以下介绍：精密微型齿轮泵主要分为：渐开线斜齿轮泵、直齿轮齿轮泵、圆弧齿轮泵、低压齿轮泵、高压齿轮泵、磁力齿轮泵、不锈钢齿轮泵、铸钢齿轮泵、铸铁齿轮泵、机械密封齿轮泵、填料密封齿轮泵、铜齿轮泵、防爆齿轮泵、高真空齿轮泵等等。

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. 

精密微型齿轮泵降低噪音方法：

Precision micro gear pump noise reduction methods:

精密微型齿轮泵噪声重要是气体/液体在输送过程中产生的空气动力噪声，电机机壳受振动激发的结构噪声，机座因振动产生的噪声，以及电动机的噪声。此类噪声级峰值重要集中在低倍频带，大约在100-450Hz的范围内。该声源在齿轮泵泵房正常运行时属于稳态噪声。管道噪声是指介质在管道中流动时所产生的噪声。另外，齿轮泵的气蚀征象及停泵水锤征象也能够产生瞬时噪声。给水管道产生的噪声，受流速和压力影响。

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.

精密微型齿轮泵房整套设施产生的噪声重要为机械噪声，目前声学原理上治理噪音的方法较常使用的是控制噪声的传播途径，重要有隔声、吸声、消声等。隔声是行使隔声结构将声源与受声点隔开；吸声是行使吸声结构或吸声材料降低噪声；消声是行使阻抗、抗性、多孔扩散等原理，降低噪声量值。

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.

噪声控制措施应根据声学原理，尽量充分行使场地环境和条件。如：1、根据泵房环境，将声源封闭不精密的泵房进行隔音处理，将泵房产生噪声的房间采取吸声/隔声处理，门窗也要做隔音处理等。2、控制机器设备和设备零件产生的噪声。新建泵房水泵基础宜采用重量大的，防止振动产生噪声。而且应设橡胶隔振垫等进行隔振，从而削减振动的噪声；每个水泵机组单独设置基础，防止产生共振。在水泵吸、压水管上尽可能的采用“软性”联结。定期检修，发生题目如盘根漏水、设备零件松动，设备零件磨损紧张、机械振动等应及时维修，从而削减噪声。

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，提醒大家的一点是，我们针对不同厂家和类型的精密微型齿轮泵，工作原理和结构都会有差异，所以，对噪声源进行现场勘测和分析对泵房隔音降噪方案的设计和材料的选择都十分紧张。

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.
