no oil machine and difference of micro oil machine:
no oil machine and micro oil machine mainly refers to the air compressor in the operation process, the use of lubricating oil and the degree of pollution of compressed air. Here are the main differences between them:
use of lubricating oil:
oil-free machine: As the name suggests, this air compressor does not use lubricating oil at all during operation, so the compressed air it produces is completely oil-free.
Micro oil machine: micro oil machine in operation will use a small amount of lubricating oil, but through efficient oil and gas separation technology, can ensure that the compressed air contains only trace amounts of oil.
Compressed air quality:
oil-free machine: Because the oil-free machine does not use lubricating oil at all, the compressed air it produces is very pure and suitable for occasions with extremely high air quality requirements.
Micro oil machine: Although the micro oil machine uses lubricating oil, the compressed air quality produced by it is relatively high through efficient separation technology, but it may not be suitable for some applications with extremely high air quality requirements.
Maintenance and cost:
no oil machine: no oil machine because it does not need to deal with lubricating oil, so its maintenance is relatively simple, and long-term operating costs are low.
Micro oil machine: The micro oil machine needs regular inspection and maintenance of the lubrication system to ensure its normal operation and compressed air quality. In addition, due to the use of lubricating oil, its long-term operating costs may be slightly higher.
Application Scenarios:
oil-free machine: oil-free machine is especially suitable for food, medicine, electronics and other industries that have strict requirements on the quality of compressed air.
Micro oil machine: micro oil machine is widely used in general industrial fields, such as machinery manufacturing, chemical industry, these industries on the quality of compressed air requirements may not be so strict.

Question: What factors should be considered when choosing a non-oil machine or a micro-oil machine?
Answer: When choosing a non-oil machine or a micro-oil machine, the following factors should be considered:
air quality requirements: First of all, it needs to be selected according to the specific application requirements for compressed air quality. If there are strict requirements on air quality, such as food, medicine and other industries, oil-free oil machine should be selected; if it is used in general industry, micro oil machine may be more suitable.
Cost considerations: The price of non-oil machine is usually higher, but the long-term operating cost is lower; while the price of micro-oil machine is relatively low, but the consumption and maintenance costs of lubricating oil need to be considered.
Maintenance and maintenance: Oil-free maintenance is relatively simple; micro-oil machines need regular inspection and maintenance of the lubrication system.
Environmental friendliness: no oil machine does not produce oil pollution, more friendly to the environment; micro oil machine although the use of lubricating oil, but through efficient separation technology can minimize the impact on the environment.
In summary, the choice of oil-free or micro oil machine should be based on specific needs and application scenarios for comprehensive consideration. Shanghai Granklin Group provides many types of air compressors, including oil-free air compressors and micro-oil air compressors, which can meet the needs of different industries and applications.
Take a look at it every day, check it every week, and do physical examination every month. The water lubricated air compressor should pay more attention to the water circulation and water quality at this rhythm. The overall inspection burden is lighter than that of traditional machines.
The use of large oil-free air compressor is quite extensive, mainly due to the characteristics of its compressed air does not contain oil. The following are some specific application areas: Electronics industry: oil-free air compressors can continuously provide clean compressed gas to meet the requirements of the electronics industry for zero
The comparison between screw air compressor and piston air compressor in terms of power saving is not an absolute conclusion, but depends on a variety of factors. The following is an analysis of some key points of the two in terms of power saving: the power saving advantages of screw air compressor are simple in structure and low in maintenance probability: screw
The maintenance of the low-pressure screw air compressor is the key to ensure its long-term stable operation and extended service life. The following are some key maintenance steps and precautions: 1. regular inspection and replacement of the filter The role of the filter: the screw air compressor needs to make
The power of the air compressor needs to be considered comprehensively, including the gas consumption, working pressure, running time, pipeline pressure loss, altitude and ambient temperature of the gas equipment. The following are some specific guidelines: 1. determine the gas consumption of gas-using equipment and
The reason why there is water in the air compressor: there is a certain humidity in the air, which contains a certain amount of moisture. When the air is sucked into the compressor for compression, due to the high temperature inside the compressor, the moisture directly evaporates to form water vapor, which will be discharged and compressed with pressure.
The design service life of the air storage tank pressure vessel is mainly affected by a number of factors, the following is a detailed summary and analysis of these factors: design life and standards: the air storage tank in the design stage will be based on the design standards and specifications to determine a set.
The mineral water bottle blowing machine does need to be equipped with high-pressure and low-pressure air at the same time. Its working principle and technological process determine the demand for different pressure air. The details are as follows: Working principle and air demand Preheating stage: The preform (embryo) is heated and softened by an infrared high-temperature lamp, this stage
The screw air compressor does not have to work all the time, but runs and stops according to actual needs. The following is a detailed explanation of the working status of the screw air compressor: Working principle and characteristics The screw air compressor is a positive displacement compressor, which is placed parallel to each other and mutually
Air compressor specific power analysis and selection suggestions specific power is a key indicator to measure the energy efficiency of air compressor, which refers to the ratio of electric energy consumed by equipment in producing compressed air per unit time to gas production. In layman's terms, the lower the specific power, means that each cubic meter of compressed air is produced.
