What is the difference between an oil compressor and an oil-free compressor?
When many people see this problem, they will think that oil-free air compressors are definitely oil-free, and oil-free air compressors are all oil-free.
But in fact, this statement is not rigorous. Today, I 'd like to introduce these two in detail. Oil-injected screw compressor is a kind of oil compressor, which refers to the compressor with lubricating oil in the compression chamber of the main engine.
Oil-free screw compressor is a kind of oil-free compressor, that is, there is no lubricating oil in the compression chamber to participate in the compression process, such as oil-free screw compressor, oil-free scroll compressor, oil-free rotary gear compressor, water screw compressor, centrifugal compressor, these are oil-free compressor series products.
Therefore, because there is no oil, the main difference is whether there is lubricating oil in the compression chamber.
As an important part of the compressed air system, the air compressor should be selected according to the gas needs.
The advantages and disadvantages of permanent magnet variable frequency air compressor are in the era of energy saving. No matter what kind of products we choose, we will include its energy saving effect as a reference value for purchasing. In the past two years, a new type of permanent magnet variable frequency air compressor has been developed in the field of air compressors.
Air compressors can share a grid with other equipment, but specific conditions need to be met to avoid problems such as voltage drop, three-phase current imbalance and electromagnetic interference. The following is a specific analysis: the feasibility of the shared grid conditions voltage stability: air compressor operation on the voltage wave.
The working temperature of the water-lubricated air compressor should be within a certain normal range to ensure the stable operation of the equipment. Generally speaking, the normal working temperature of the water lubricated air compressor should be between 60 ℃ and 70 ℃. In case of low ambient temperature, water lubricated air compressor
There are significant differences between the suction dryer (adsorption dryer) and the cold dryer (freeze dryer) in many aspects, which are mainly reflected in the working principle, drying effect, energy consumption, maintenance cost and applicable scenarios. The following is a detailed comparison: 1. working principle
The difference between 8kg air compressor and 5kg air compressor is mainly reflected in the exhaust pressure, application scenarios and possible energy consumption differences. The following is a detailed summary of these differences: Exhaust pressure: 8kg Air compressor: Its exhaust pressure is 8kg, also
Q: Air compressor cold dryer boot sequence? Answer: first open the cold dryer, and then open the air compressor. Turn off the air compressor first, then turn off the cold dryer.
The oil content of the exhaust gas of the micro-oil screw machine usually contains 30 to 40 mg of oil per cubic meter of compressed air, equivalent to 30ppm to 40ppm, but the actual value may vary due to factors such as equipment model, brand, operating conditions, etc. The following is the specific analysis: 1. standard conditions
Oil-free rotary air compressor and oil-free screw air compressor have their own unique advantages and disadvantages, which is better depends on the actual application scenarios and needs. The advantages of oil-free rotary tooth air compressors include: oil-free, so there is no need to change the air compressor oil, free
The compressor needs to discharge water regularly. The main reasons and necessity are as follows: 1. the causes of condensed water Air compression process The air itself contains a certain amount of humidity (moisture). When the air is compressed, the temperature rise causes the water vapor to reach a saturated state, and the excess water vapor will condense
There is a close and complex relationship between the power, exhaust flow and pressure of the air compressor, which affects the performance and efficiency of the air compressor. First of all, power is a measure of the energy required for the operation of the air compressor, which is directly related to the working condition of the air compressor motor.
