The units of the vibration value of the air compressor are usually the following, which are used to measure different aspects of vibration:
speed (mm/s):
the amount of vibration of the air compressor is usually expressed by the speed value, and the unit is mm/s (mm/s).
According to international standards, the vibration speed of mechanical equipment is usually considered normal below 2.5 mm/s.
Acceleration (g):
peak acceleration refers to the maximum value of vibration acceleration per unit time, usually expressed in g (acceleration of gravity).
According to the mechanical industry standard, the standard value of the peak acceleration of the air compressor should be less than 2g, and repair and maintenance are required if this value is exceeded.
Displacement (mm or um):
amplitude refers to the maximum displacement of vibration, usually in millimeters (mm) or micrometers (um).
The mechanical industry standard stipulates that the amplitude of the air compressor should not exceed 0.2mm.
Frequency (Hz):
frequency refers to the number of repetitions of the vibration in Hertz (Hz).
For the screw air compressor motor, the vibration frequency of the bearing in the horizontal direction should be below 10Hz, and the vibration frequency in the vertical direction should be below 5Hz.
In summary, the units of the vibration value of the air compressor mainly include speed (mm/s), acceleration (g), displacement (mm or um) and frequency (Hz). These units are used to measure the speed, acceleration, displacement and frequency of vibration, so as to fully evaluate the vibration of the air compressor. In practical applications, the appropriate vibration value unit should be selected according to specific requirements and equipment specifications, and the vibration value should be within the standard range to ensure the normal operation and service life of the equipment.
As the key equipment in industrial production, the performance and quality of air compressor directly affect the production efficiency and product quality. In many fields, several industries have particularly strict requirements for air compressors, and the water-lubricated screw air compressor products produced by Shanghai Granklin Group
Yes, the additive industry does use air compressors. In the production process of additives, air compressors can provide power or compressed gas. These gases have many uses in the production line, including but not limited to pneumatic conveying, mixing, mixing and other process links. Therefore
The distinction between oil air compressor and oil-free air compressor can be judged comprehensively by the following methods: 1. Observe the structure of the equipment with oil air compressor: there are usually oil filters, oil and gas separators and other components for filtering the oil in the compressed air. The fuselage may have a fuel filler or oil dipstick (use
Description of the dew point of compressed air in the pharmaceutical industry The dew point is a key indicator to measure the moisture content in compressed air. It refers to the temperature at which the gas is cooled to the temperature at which water vapor begins to condense into liquid water. The lower the dew point, the lower the moisture content in the compressed air. Pharmaceutical Industry Pressure
The air pressure of the industrial compressed air used in the general factory will be determined according to the specific application and equipment requirements. In most cases, the common compressed air pressure range is usually between 7bar and 10bar (Note: 1 bar & asymp; 100,000 Pa = 1
As an indispensable equipment in the industrial field, the safety and stability of the air compressor has a vital impact on the normal operation of the enterprise. In order to ensure the safe operation of the air compressor, a series of safety issues need to be checked regularly. The following is based on
In compressed air technology, the structural difference between oil-free and oil-free compressors is crucial, which determines the performance, efficiency and purity of the output gas of the compressor. In recent years, the water-lubricated screw air compressor produced by Shanghai Granklin Group has been
Compressed air oil content standards refer to the content limit of oil substances in compressed air to ensure the quality of compressed air and meet the requirements of specific applications. Different industries and applications may have different standards for compressed air oil content, usually in mg/cubic
The compressed air of 0.6MPa is not absolutely safe in the production process, and its safety depends on the specific use scenario, equipment condition, operation specification and whether the protective measures are in place. The following is a detailed analysis of its safety: the risk of compressed air itself pressure wind
The replacement cycle of the air filter (air filter) of the air compressor is not fixed. It depends on many factors, including the use environment of the air compressor, air quality, running time and the quality of the filter. Generally speaking, the replacement cycle of the filter can be based on the manufacturer
