Water lubricated air compressor and oil lubricated air compressor have their own advantages and disadvantages, which is better depends on the specific application scenarios and needs. Here is a comparison of the two:
water lubricated air compressor:
advantages:
environmental protection: The use of pure water for lubrication and cooling ensures that the compressed gas is pure and oil-free, and has no pollution to the environment.
High efficiency: The specific heat capacity of water is large, so the heat generated during the compression process can be effectively absorbed by the water, which reduces the operating temperature of the equipment and improves the service life and energy efficiency of the equipment.
Low maintenance cost: The equipment structure is relatively simple, the number of parts is small, and the maintenance cost is reduced.
Disadvantages:
the water needs to be replaced regularly: to ensure the quality of the water and the normal operation of the equipment.
There are certain requirements for water quality: if the water contains impurities or microorganisms, it may cause damage to the equipment.
There is a risk of condensation in certain high humidity environments.
oil lubricated air compressor:
advantages:
high efficiency: Oil lubrication can ensure the smooth operation of the machine, so its service life is relatively long, and the work efficiency is also high.
Widely used: Oil-lubricated air compressors occupy a dominant position in the market, with mature technology and wide application.
Disadvantages:
environmental pollution: oil lubrication will produce smoke and oil pollution, causing some pollution to the environment.
Maintenance costs: regular replacement of oil products will increase maintenance costs.
Safety in use: Pay attention to safety during use, such as preventing oil fume from catching fire.
In summary, water-lubricated air compressors and oil-lubricated air compressors have their own advantages and disadvantages. When choosing, it should be considered comprehensively according to the specific application scenario, environmental protection requirements, maintenance cost and safety of use. For example, in pharmaceutical, food and other industries that require high gas purity, water-lubricated air compressors may be more appropriate; and in some occasions where environmental pollution requirements are not so strict, oil-lubricated air compressors may be more economical and practical.
The compressed air used in the production of puffed food must be clean air that does not contain oil, has very low moisture, has no dust and bacteria, and has no peculiar smell. Water lubricated air compressor is becoming a more and more popular gas supply choice for food production enterprises because it solves the problem of oil pollution from the source.
The amount of compressed air used in the blow molding process depends on a variety of factors, including the model of the blow molding machine, the size and shape of the product, the production speed, and the specific process parameters in the blow molding process. Therefore, it is not possible to give specific usage figures, but it can provide some shadow.
Purchase air compressor need to know the data, different air compressor data is not the same, need to match the appropriate air compressor according to the specific use of the scene, after understanding the basic data of the series of air compressor to better purchase.
Shanghai Granklin Group water lubricated oil-free screw air compressor manufacturer, our air compressor adopts water lubrication, and the gas does not contain oil is a very ideal oil-free air compressor. More and more users use oil-free screw air compressor. However, many people do not pay attention to the use of the process will be a variety of failures. How to reduce the occurrence of failure?
View detailsIn modern industrial production, air compressor as an important power equipment, its performance and efficiency is directly related to the production cost and operational efficiency of enterprises. Recently, I had the honor to experience the water-lubricated screw air compressor produced by Shanghai Granklin Group, which uses permanent magnet frequency conversion.
In today's era of increasing emphasis on environmental protection and energy saving, oil-free water lubrication air compressor head with its unique advantages, has become the first choice of many industries. As a leader in the compressor field, Shanghai Granklin Group produces more water-lubricated screw air compressors.
Correct daily maintenance and use can extend the service life of the oil-free air compressor and avoid or reduce the occurrence of failures. Accurate use environment: 1) The normal use environment of the air compressor is 5 ℃-40 ℃
Whether the air compressor belongs to the category of special equipment can be summarized from the following points: the definition of special equipment: special equipment refers to the equipment involving life safety and high risk, including boilers, pressure vessels (including gas cylinders), pressure pipes, elevators,
Whether the air compressor room needs to use explosion-proof fans shall be determined according to the risk of explosive substances in the room environment. If there are flammable and explosive gases, dust or combustible substances in the machine room, and its concentration may reach the explosion limit, explosion-proof fans must be used;
There may be many reasons for the loud sound of the screw machine. The following are some possible reasons: The main engine is unbalanced: When the screw compressor is running, if the rotor of the main engine is unbalanced, vibration and noise will be generated. This may be due to rotor design or manufacturing issues, or
