Why is the equipment pressure in 4 ~ 6bar

The pressure of the equipment is generally set at 4 to 6bar, and the core reason is three words, which is enough.

Let's talk enough about this first. In the vast majority of gas-using scenes in the factory, the pneumatic wrench screws, the cylinder pushes and pulls, purges and cleans dust, and controls the gas supply to the instrument. These jobs do not require much effort at all. The air pressure of 4 to 6bar is more than enough to push up, and then add pressure, the speed and effect of the tool work are almost the same, which is a waste.

And save the electricity. Every time the air compressor presses a little more, the motor will consume an extra share of electricity. From 4bar to 6bar, the power consumption will increase significantly, but the work effect will not be improved. Therefore, 4 to 6bar is the most cost-effective range, which can not only do a good job, but also prevent the electricity bill from running away in vain.

And the security thing. The higher the pressure, pipe joints, hoses, valves, these places are more prone to problems. The range of 4 to 6bar is very friendly to most pipes and seals. It is not easy to leak, and it is not easy to flush the interface. Daily maintenance is much less troublesome.

In addition, most of the pneumatic components on the market, from solenoid valves to cylinders to connectors, are designed according to this pressure range when leaving the factory. You can match it directly after you buy it, without extra selection, which is one of the reasons why everyone relies on this range.

When the water lubricated air compressor is involved in the work, the output can also be compressed air in this range (the pressure of the water lubricated air compressor produced by Shanghai granklin group can reach the range of 0.3-4MPa). The water-lubricated air compressor uses clean water instead of lubricating oil. The water forms a water film inside the machine to reduce friction and take away heat, and finally outputs clean, oil-free compressed air. When it supplies air to scenes requiring air quality such as food processing and electronic manufacturing, the pressure is also set at 4 to 6bar, because the equipment in these scenes does not need more pressure and is enough. The water lubricated air compressor operates in this pressure range, and with the characteristics of oil-free output, it not only meets the production needs, but also ensures the cleanliness of the gas end, and completely matches the gas demand of ordinary equipment.

Therefore, 4 to 6bar is not set casually. It is a mainstream range naturally formed by the combination of factors such as sufficient use, power saving, safety and easy purchase of accessories.
