Air compressors with oil and without oil are not absolutely good or bad. Their use occasions are different from those suitable for working conditions. If they are used for purging, mechanical processing, manufacturing and power use, it is OK to choose air compressors with oil and micro oil. However, oil-free air compressors must be used in some occasions, such as food, medicine, precision instruments and other industries. Oil-free air compressors are cleaner and more environmentally friendly than oil-free air compressors to some extent, but oil-free air compressors are more expensive than oil-free air compressors and have higher maintenance costs.
In addition to the price, oil-free air compressor and oil air compressor has the following differences:
1. The oil content is different. Generally, the oil content of the oil machine is larger, and the oil content of the oil machine is 0.01ppm, so this oil content is used to distinguish the air compressor with oil and without oil. There is also a full oil-free air compressor, which is lubricated by water, so the final discharge of gas does not contain oil, called a full oil-free air compressor.
2. The structure is different. Whether it is an oil-free piston machine or an oil-free screw machine, a large amount of high temperature will be generated during the operation. The participation of oil in the air compressor will take away the high temperature generated during the compression process of the air compressor, thereby Cooling the machinery. The oil-free air compressor uses water to lubricate the air compressor head, and the heat generated inside the air compressor head is taken away by the water, achieving isothermal compression.
In applications, industries with higher gas requirements are better to use oil-free air compressors.
Oil-free air compressor is cleaner and more environmentally friendly than oil-free air compressor to some extent, so institutions such as hospitals, laboratories, schools and other institutions are very suitable for the use of oil-free air compressor, and these institutions also prefer to use oil-free air compressor.
The core method to identify whether the air compressor is oil-bearing equipment 1. Observe the structural characteristics of the equipment Oil containing air compressor is usually equipped with oil system, including oil tank, oil pump, oil cooler and oil separator and other components. If the tubing interface, oil filter element or oil is visible on the appearance of the equipment
The maximum air production capacity of the air compressor refers to the maximum amount of compressed air that the air compressor can produce per unit time, usually expressed in cubic meters per minute (m & sup3;/min) or cubic feet per minute (cfm). The amount of use refers to the actual application of various gases.
Compressed air, as an important infrastructure of the modern medical system, undertakes multiple key functions in the ward environment, which is directly related to the safety of patients and the quality of medical care. Comprehensive technical analysis and industry practice
There are significant differences between oil-free air compressor and oil-free air compressor in terms of working principle, performance and application field. Working principle: The oil piston air compressor will be connected with lubricating oil during the compression process to help seal, cool and lubricate, thereby improving the machine's
Answer: Screw machine and scroll machine are two common air compressors, which are often used in air compression, gas transportation and other fields in industrial production and manufacturing.
In the air compressor system, there is a clear physical relationship between pressure, flow and power, which can be analyzed by theoretical formulas and practical application scenarios. The following is a detailed explanation of the relationship between the three: 1. core formula: the proportional relationship between power and flow and pressure
Nitrogen is widely used in the electronics industry, mainly as a protective gas, clean gas and process gas, and its purity usually needs to reach more than 99.999 percent to meet the stringent requirements of the electronics industry for product quality. The following is the specific application of nitrogen in the electronics industry and
How long should the air compressor be maintained? 1. The first regular maintenance time of the air compressor is 500 hours, and the oil filter, air filter element and lubricating oil should be replaced for 500 hours. 2. Do major maintenance every 3000 hours after the initial maintenance. 3
When looking for high-quality screw-type air compressors, many companies will ask: "Which is the best screw-type air compressor?" On this issue, Shanghai Grankering Group has become a highly respected product in the industry with its excellent water-lubricated screw air compressor products.
