Silent air compressor works

Silent air compressor design The main core of the silent air compressor is the sound reduction effect of its outer casing, as well as the reduction of the machine speed, the muffler of the intake and exhaust, and the matching of the head and the motor. Aspects are designed.

The periphery of the silent air compressor is mainly designed with noise-reducing sound insulation. Its cabinet cover is assembled with sound-insulating materials. Silent air compressors are divided into oil silent air compressors and oil-free silent air compressors. Oil is a silent air compressor, usually with a noise of about 40 decibels; the oil-free silent air compressor has a noise of about 60 decibels. The air compressor works with very low sound and can meet all indoor use requirements, such as research, laboratory, hospital, office, student classroom, family and other environments. The ratio of pressure and gas production is in the ratio of gold, and the most energy source can be produced most quickly under the condition of minimum energy consumption, and the start and stop of the machine are all automated design.

The noise of the silent air compressor is the oil-free silent air compressor. The main noise source is the intake and exhaust ports. The appropriate intake and exhaust muffler should be used. The spectrum of the intake noise of the oil-free silent air compressor is characterized by low frequency, and the intake muffler should adopt a resistant structure or a resistance-composite structure with resistance and resistance. The oil-free air compressor has a large exhaust gas pressure and a high airflow speed. A small-hole muffler should be used at the exhaust port of the oil-free silent air compressor. After the muffler is installed in the inlet and exhaust ports of the oil-free silent air compressor or the muffler tunnel is installed, the airflow noise can be reduced to below 80db(a), but the mechanical noise and motor noise of the oil-free silent air compressor are still high. Therefore, an acoustic enclosure should also be installed on the unit of the oil-free silent air compressor.

Silent air compressor pressure ratio Under the required exhaust pressure, the volume of gas discharged per unit time of the oil-free silent air compressor is converted into the intake state, that is, the suction pressure and suction at the first-stage intake nozzle Volume value at gas temperature and humidity. If the speed does not change, the pressure change theoretically does not affect the displacement, specifically, affects the volume flow, does not affect the mass flow. Since the amount of exhaust gas we generally refer to refers to the intake air flow, there is no change. For a multi-stage compressor, the pressure ratio is also referred to as the total pressure ratio, which is the ratio of the exhaust pressure measured at the end of the exhaust pipe to the suction pressure measured at the first intake manifold. The ratio of nominal suction and discharge pressures at each level is called the pressure ratio of the stage.

Generally, the silent air compressors use piston air compressors, and the mute effect and the ultra-quiet air compressor have a certain gap. The ultra-quiet air compressor adopts a scroll type, and the sound of the vortex air compressor itself is very small. In addition, the sound insulation and the muffler are arranged, and the general effect can reach about 20 decibels.
