Screw air compressor in the process of gas production, noise is very headache, if the air compressor and the production department distance is relatively close, a long time will affect our hearing, we will generally install the air compressor in the corner of the factory, far away from the production and processing personnel, but some small enterprises site problems can not guarantee the distance, at this time we must find ways to reduce the noise of the machine.
Granklin water lubricated air compressor noise between 57-80 dB, the greater the power of the machine, the noise will increase accordingly.
screw air compressor mainly has two parts: pneumatic noise and mechanical noise. Aerodynamic noise is caused by periodic intake and exhaust noise, eddy current noise and rotating noise. Mechanical noise is caused by gear noise, pipeline vibration and fan noise.
Measures to control and reduce noise are:
1. improving the structure and processing technology, controlling the noise source, correctly selecting the rotor profile, improving the flow state of the airflow in the cylinder, reducing the eddy current loss, selecting a reasonable speed, improving the dynamic balance of the rotor, equipped with low-noise gears and improving the design and manufacture of cooling fans.
Acoustic enclosure and sound absorption screen are 2. provided. Box-shaped full-cover low-noise fast installation can reduce noise by 20 ~ 30dB(A).
3. room for sound insulation and sound absorption treatment.
4. set the muffler. In the intake and exhaust ports are respectively set up intake and exhaust muffler, can reduce the noise of about 25dB(A).
The traditional air compressor drainage is to discharge waste water, which is as clean as possible but not serious. Water lubricated air compressor drainage is the discharge of excess condensed water, circulating water to stay. Either way, stopping the front row once is the most basic operating habit.
When choosing an air compressor, the two types of oil-free and oil have their own advantages, just like two artists of different styles, each has its own unique charm and advantages. Oil-free air compressor, like a pursuit of pure painter, its works-compressed empty
In the supporting equipment of the blow molding machine, the air compressor is an indispensable part, and the choice of its pressure is directly related to the blowing efficiency and product quality. For the bottle blowing air compressor, the choice of pressure should be determined according to the specific application scenario and the requirements of the bottle blowing machine. General
The frequency conversion and power frequency of the air compressor have their own advantages and disadvantages, and the specific choice depends on the actual needs and scenarios. Power frequency air compressor: Advantages: simple structure and convenient maintenance. The initial purchase cost is relatively low. Disadvantages: higher energy consumption, especially in
The pressure of the compressed air in the factory will generally be determined according to the specific application requirements and equipment specifications. Generally, the normal pressure range of industrial compressed air is 0.6~0.8MPa, but in practical applications, this range may be changed. In some common jobs.
How many hours does it take for the normal maintenance of the air compressor: The maintenance cycle of the air compressor is not entirely determined by the operating hours, it also depends on the working environment, load conditions, air quality, and manufacturer's recommendations. However, in general, air compressors need
There are significant differences between water-lubricated air compressors and dry oil-free air compressors in many aspects: Lubrication method: Water-lubricated air compressors use water as a lubricant, thanks to the specially designed head, which can mix water and air Mixing to achieve the dual functions of lubrication and compression
When the air compressor is set or adjusted to 8kg, it means that the compressed air pressure output by the air compressor is 8kg force/square centimeter (kgf/cm²). In the field of air compressors, pressure is usually measured in units such as kilograms of force per square centimeter (kgf/cm²) or bar (bar).
Medical air compressor is a special equipment for the hospital to produce clean compressed air, and water lubricated air compressor because of water instead of oil, so that the production of air is more pure, especially suitable for use in hospitals such a place with high air quality requirements, silently guarding the safety of patients.
The daily running time of the water plant air compressor is not fixed, but is affected by a variety of factors, including the size of the water plant, processing capacity, equipment performance, maintenance status and power supply. The following is the daily operation of the water plant air compressor
