    花开棋牌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.

    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.

    花开棋牌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.

    花开棋牌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.

    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.
