With the wide application of screw air compressor and the increasing demand of the market, oil-free screw air compressor has become more and more popular in the market in recent years. There are also many customers who will ask questions about oil-free screw air compressors. Today, the editor will briefly talk to everyone about the oil-free screw air compressor can be roughly divided into several categories: water lubrication type, dry grinding type, and reciprocating type.
1. water lubricated
since the oil-free air compressor uses stainless steel and ceramic composite rotors, its dynamic bearing system is completely oil-free. And because the water spray can reduce the speed of the equipment, the volumetric efficiency of water lubrication oil-free air pressure is higher.
2. dry grinding type
when the dry grinding oil-free air compressor is in operation, its screw rotor generates gas compression through high-speed expansion, and the screw of the dry grinding oil-free air compressor is sprayed with resin objects to protect the screw from high-speed friction. Damage.
3. reciprocating
miniature reciprocating oil-free air compressor motor single-axis drive, symmetrical distribution crank rocker mechanical structure. The arrangement of the single-shaft double-cylinder structure of the reciprocating oil-free air compressor can make the air flow of the equipment double the speed of the single-cylinder in the rated range, so as to solve the vibration and noise generated by the single-cylinder compressor well.
Of course, different industries have different requirements for oil-free air compressors, and users can choose according to their own production conditions.
The moisture content in atmospheric air is usually expressed in terms of "relative humidity", that is, the amount of water vapor actually contained in the air as a percentage of the maximum water capacity of the air at that temperature. For example, a relative humidity of 60% means that the current amount of water vapor in the air is the same temperature.
The requirements of the electronics industry for compressed air usually include the following aspects: Purity: Due to the precision of electronic products and the high requirements for the production environment, compressed air must be very pure. This includes the control of solid particles, oil, microorganisms and other contaminants.
Oil-free air compressor, as its name reveals, is an air compressor that does not require the use of oil for lubrication. This machine is particularly suitable for those who have strict requirements on the air quality of the environment, because it can ensure that the compressed air is completely free of oil, non
The gas produced by the oil-free air compressor may contain trace amounts of water, but the water content is usually low. The working principle of the oil-free air compressor is mainly to compress the inhaled air through mechanical parts such as pistons, screws or turbines, and then output it as high-pressure gas. In
Whether the air compressor is explosion-proof electrical equipment depends on its design and working environment. The following is a detailed answer: the definition of 1. explosion-proof electrical equipment explosion-proof electrical equipment refers to the design of explosive environment (such as flammable gas, steam, dust and other places) electrical equipment
The end-of-life of screw air compressor is not a fixed value, but is affected by many factors. These factors include, but are not limited to, equipment quality, use environment, maintenance, and operating specifications. Overview of end-of-life In general, screw
Whether the air compressor needs to be refueled depends on the type of air compressor. When the reciprocating piston of the piston air compressor moves to the right in the cylinder, the pressure in the left cavity of the piston in the cylinder is lower than the atmospheric pressure, the suction valve opens, and outside air is sucked into the cylinder.
The speed of the air compressor motor varies depending on the type of equipment, specifications and manufacturer, but can usually be found in a relatively clear range. Generally speaking, the speed design of the air compressor motor will take into account the working efficiency, energy consumption and service life of the equipment.
Air compressor has been working does not stop, may be caused by a variety of reasons. The following are some possible reasons and corresponding solutions: Possible reasons and solutions Causes of pipeline leakage: There is a leakage problem in the compressed air pipeline, and the air compressor will be unable to reach it.
The replacement cycle of the three filters of the air compressor can be determined according to different filters and specific usage. The following are some general guidelines: Air filter: Non-original general use time is 2000 hours, but it can be based on actual air quality and
