The noise sources of the screw unit are diversified, mainly including the following aspects:
first of all, when the screw compressor is running, there will be friction and collision between the screw and the shell, which is a major source of noise. This mechanical friction and collision will not only produce high-frequency noise, but also may affect the stability and life of the unit.
Secondly, when the unit is running, the internal cooling fan and motor will also make noise. The cooling fan rotates at high speed for heat dissipation, and the wind noise generated is an important part of the unit noise. At the same time, the motor in operation will also produce electromagnetic noise and mechanical noise, these noises will be transmitted through the unit shell and pipe.
In addition, the screw unit will also produce vibration during operation. This vibration will not only cause damage to the unit itself, but also spread to the surrounding environment through the foundation and pipeline, forming noise pollution. The generation of vibration is mainly related to the manufacturing accuracy, installation quality and operating conditions of the unit.
Finally, the screw unit in the intake and exhaust process, due to the flow and compression of gas, will also produce a certain amount of noise. The size of this noise is related to the gas flow rate, pressure and the design of the unit.
In summary, the noise sources of the screw unit mainly include the mechanical noise of the screw compressor, the noise of the cooling fan and the motor, the vibration of the unit, and the gas noise during the intake and exhaust process. In order to reduce the noise of the unit, we can start from improving the design of the unit, improving the manufacturing accuracy, strengthening the installation and maintenance, etc., to reduce the generation and transmission of noise.
The calculation method of air compressor gas production involves many factors. The following is a detailed summary of the calculation method of air compressor gas production: 1. basic calculation formula Formula 1: gas production (m & sup3;/min)= input pressure (MPa)× exhaust volume (m & sup3;/m
An air compressor is a mechanical equipment that compresses air in the atmosphere into high-pressure gas, stores it in an air storage tank, and delivers it to various pneumatic tools or equipment through pipelines when needed to provide power for it. Its application range is extremely wide, covering almost all work.
Today, with the rapid development of air compressor technology, single-stage screw water lubrication technology has gradually become the new darling of the industry with its high efficiency and environmental protection characteristics. When it comes to the leader of this technology, the water-lubricated screw air compressor produced by Shanghai Granklin Group is undoubtedly a bright.
In the production process of the bottle blowing plant, the air compressor is one of the key equipment, and its performance and stability directly affect the operating efficiency and product quality of the bottle blowing machine. For whether to choose water lubricated air compressor, this is indeed a problem worthy of in-depth discussion. water lubricated air
The content of ppm in the air is the unit of gas concentration, that is, the abbreviation of "parts per million", which can be translated as "parts per million" in Chinese ". It refers to the proportion of a gas component in the air, specifically expressed per hundred
Air compressor maintenance does not necessarily have to be carried out by the manufacturer, but choosing the manufacturer to carry out maintenance does have its advantages. The following is a detailed analysis of this problem: air compressor maintenance definition and content definition: air compressor maintenance refers to the maintenance and maintenance of the air compressor to ensure its
When discussing which is better, we need to consider their respective characteristics and application scenarios. The water-lubricated screw air compressor produced by Shanghai Granklin Group, with its unique advantages, provides us with a valuable reference
The oil content of compressed air ≤ 0.01 mg/m & sup3; is not micro-oil, but belongs to the international standard ISO 8573-1 Class 0 (Class 0) standard, which is usually regarded as equivalent to the oil content of oil-free compressed air. The following is a detailed explanation of this conclusion: the 1. State
The working temperature of the water-lubricated air compressor should be within a certain normal range to ensure the stable operation of the equipment. Generally speaking, the normal working temperature of the water lubricated air compressor should be between 60 ℃ and 70 ℃. In case of low ambient temperature, water lubricated air compressor
Air compressors can be divided into oil-containing air compressors, micro-oil air compressors and oil-free air compressors according to whether they contain oil. Oil-free air compressors usually do not contain any oil. Oil-free air compressors are virtually oil-free. The air compressor lubricated with resin material is truly oil-free
