The normal range of the vibration value of the air compressor host depends on the specific equipment model and application scenario. In general, here are some common reference ranges for vibration values:
for the main compressor types such as screw air compressor or axial flow turbine, under normal operation, the horizontal vibration value should not exceed 0.2mm (base vibration), and the vertical vibration value should not exceed 0.3mm (main shaft vibration). These standards apply primarily to vibration measurements under normal operating conditions.
For motors, the general vibration range should be within 3 channels (I. e. 0.03mm). In particular, such as 75kw air compressor, the standard vibration value in specific test conditions (such as the ISO2372 10-1KHz range) have specific provisions, the better vibration value range is 2.0-4.5 mm/s, excellent vibration value range is 0.45-1.8 mm/s.
There are also some views that the head vibration value of the air compressor should be less than 7.5 mm/s, but this may vary depending on the type of air compressor or application scenario.
International standards stipulate that the vibration speed of mechanical equipment should be less than 2.5 mm/s, and exceeding this value may be regarded as abnormal.
It should be emphasized that these vibration values are for reference only, and specific vibration standards may vary according to different manufacturers, models and specifications. In order to ensure the normal operation of the air compressor and prolong the service life, the vibration value should be monitored regularly. Once abnormal vibration is found, corresponding measures should be taken in time, such as maintenance, repair or replacement of parts.
In general, for a specific air compressor, the most accurate and safe practice is to refer to the manufacturer's operation and maintenance manual, understand and follow the vibration value regulations for the equipment.
Comparative Analysis of Permanent Magnet Variable Frequency Air Compressor and Granklin Water Lubricated Single Screw Air Compressor In the field of industrial compressed air equipment, permanent magnet variable frequency air compressor and Granklin water lubricated single screw air compressor occupy an important position with their unique technical advantages. The following from the original work
The standard specification for air used in aseptic workshop mainly involves the cleanliness, temperature and humidity, air flow organization, air change frequency, static pressure difference and air filtration system. The following is a detailed summary of these standards: 1. air cleanliness according to ISO 14644-1
In the pursuit of efficient, environmentally friendly industrial era, oil-free air compressor with its unique advantages to become the new darling of the market. As a leader in the industry, the water-lubricated screw air compressor produced by Shanghai Granklin Group is based on its excellent performance and innovative design concept.
There are some differences between screw compressors and scroll compressors in terms of structure, working principle and application. Structure and working principle: Screw compressor: It is composed of a pair of parallel arrangement and intermeshing male and female rotors (ie screws). When the rotor turns
Biopharmaceutical enterprises have strict air quality requirements and need to meet core standards such as cleanliness, temperature and humidity, pressure difference, microbial control, air flow direction, etc. The specific requirements are as follows: 1. cleanliness level requires biopharmaceutical workshops to be divided into different types according to production process and product characteristics.
The exhaust pressure of the air compressor is usually fluctuating in actual operation, rather than a constant value. This fluctuation may be caused by equipment characteristics, load changes, control methods, environmental factors and maintenance status. The following is a detailed analysis: 1. exhaust pressure wave
Air compressor maintenance replacement time depends on a number of factors, including the type of equipment, the environment in which it is used, the workload, and the manufacturer's recommendations. Generally speaking, air compressors require regular preventive maintenance to ensure their normal operation and extend their service life.
After a period of time, the after-sales personnel of the screw air compressor will overhaul the air compressor once, replace some filter materials with short time periods of the air compressor once, and overhaul and maintain the air compressor. 1. Clean the valve, clean the valve seat, valve cover carbon deposition, cleaning
Air compressors are divided into two types: frequency conversion and fixed frequency. They have significant differences in working principle, energy consumption, maintenance cost, performance, noise level, price and application scenarios. The following is a detailed comparison of the difference between the two: frequency conversion empty
Air compressor in its use process will consume part of the accessories, in order to seize this part of the market manufacturers have also launched their own original accessories. Although the quality of the original parts is good, the price-sensitive users will still consider it again and again. Original screw air compressor
