Oil-free air compressor produces oil-free compressed air, and water-lubricated oil-free air compressor can do 100% without refueling. Air compressor head internal work only water, not a drop of lubricating oil involved.
Is the oil-free air compressor really running without oil? In fields such as biology, medicine, electronics, food, medical, cars, chemicals, etc., the water, oil, dust, bacteria, etc. in the compressed air are required to reach a higher quality level. However, the water, dust, and bacteria in the compressed air can be passed through a series of post-processing equipment such as filters and dryers to solve the problem, and oil removal is relatively difficult, the use of water-lubricated oil-free air compressor can be 100% oil-free on the machine equipment.
The compressed air produced by the oil-free air compressor is oil-free, which is not inevitable.
Although no oil is used in the compression chamber, the oil will not contact with the compressed air, but the oil vapor contained in the atmosphere itself cannot be removed, which makes the compressed air still contain a small amount of oil impurities. After measurement, the oil content in the compressed air produced by the oil-free air compressor has a very close influence on the air quality, the environment of the air compressor room and the cleanliness in the compressor in the region.
2. The compressed air produced by the oil-free air compressor is pollution-free and pure and clean. This is a wrong idea.
In fact, there are many pollutants in the atmosphere, including dust, water vapor, oil vapor, microorganisms and so on. The compressed air produced by the oil-free air compressor can only ensure that no oil is brought into the compressed air during the compression process, but the magazine in the air itself cannot be removed. This means that the compressed air produced by an oil-free compressor does not have to be pollution-free, and air treatment products are required to help reduce pollution to the required air quality level.
Oil-free air compressor does not require air treatment products, on the contrary, the higher the air quality, oil-free air compressor must also be deployed after-treatment system.
From the second point, it can be seen that a large part of the gas quality of the compressed air produced by the oil-free air compressor is subject to the environment, so the user needs to equip the corresponding post-processing equipment according to their own demand for compressed air quality.
Oil-free lubrication air compressor is not all screw type, there are many types of oil-free lubrication air compressor on the market, each type has its own unique working principle, application scenarios and advantages and disadvantages. The following is a detailed answer: 1. oil-free lubrication air compressor type oil-free piston
The service life of the air compressor filter is affected by many factors, including filtration accuracy, use environment, air quality, operating conditions, and maintenance conditions, so a uniform fixed time cannot be given. However, according to the characteristics of different types of filters and common should
The blowdown operation of the air compressor blowdown valve is relatively simple, but it needs to follow certain steps and precautions. The following are the basic steps for sewage discharge: Preparation: Make sure that the air compressor has stopped running and disconnect the power supply to ensure safe operation. Get ready.
The oil content standard of screw air compressor is usually stipulated by relevant international, national or industry standards. The following is some specific information about the oil content standard of the screw air compressor: Oil-injected screw air compressor: Generally speaking, the compressed air of the oil-injected screw air compressor contains oil
The working principle of the single-screw air compressor is mainly based on the rotation of the screw to achieve air compression. The following is a detailed description of its working principle: The single-screw air compressor is equipped with a main screw, which is driven by a motor to rotate at a high speed. Simultaneously
The main differences between air compressor frequency conversion and power frequency are reflected in the operating frequency, energy efficiency performance, starting characteristics, noise level, pressure stability, maintenance cost and applicable scenarios. The following is a detailed explanation of these differences: 1. operating frequency variable frequency
Excessive water on the ground of the screw air compressor will have many adverse effects, mainly including the following: 1. affect the normal operation of the equipment, the compression efficiency is reduced: the water will occupy a certain space inside the air compressor, which may lead to the reduction of the compression efficiency of the equipment. When accumulated water
Q: air compressor what enterprises use? A: air compressor is a general machinery, a wide range of applications. Note: The items used in our lives, special gases (oxygen, argon, nitrogen, etc.), are available during production and processing.
Air compressor in the absence of cold dryer can be short-term operation, but long-term use will bring a series of problems, affecting equipment life, product quality and production safety. The following from the principle, impact and solution three aspects of a detailed analysis: 1. the role of the cold dryer
The first maintenance of air compressor is a key link in the whole life cycle management of equipment, which plays an important role in ensuring the stability of operation and prolonging the service life. According to the general standards of the industry and the operating characteristics of the equipment, we are now 500.
