Pneumatic Technology, Frequently Asked Questions And Answers
Aug 31, 2016

A: what is technology? Pneumatic in English is?

Q: pneumatic technology is based on air compressors for power source, with compressed air as medium, energy transmission or signal engineering, which is one of the most important means of production control, automatic control. Air is "pneumatics" or "pneumatic transmission and control" abbreviation, pneumatic in English are: PNEUMATIC.

A: how the application of pneumatic technology? Which industries and equipment were applied to air?

Q: currently pneumatic technology application very widely, whenever automation of equipment are can application to pneumatic, as: car manufacturing industry in the welding line; electronic, and semiconductor manufacturing industry in the TV, and refrigerator, household appliances products of assembly line Shang, in semiconductor chip, and printed circuit, various electronic products of assembly line; automatically jet looms, and automatically cleaning machine, and metallurgical mechanical, and printing mechanical, and building mechanical, and agricultural machinery, and business shoes mechanical, and plastic products line, and leather line, and glass products processing line, ; Fertilizer, chemical, food, foods, medicines, such as automatic packaging line.

A: what are the characteristics of pneumatic technology?

Q: technology advantages: simple structure, pressure levels low, safe to use, easy to maintain, easy to install; it can realize the fire, explosion-proof, moisture-proof.

Disadvantage of pneumatics is positioning accuracy is not high, speed greatly influenced by the load. Output power far lower compared with hydraulic.

A: what pressure? What is the gauge pressure? What is the vacuum? What is vacuum? What is the relationship between them?

Q: pressure is the pressure of the vacuum as a starting point. Normally taken in the sign of the pressure right corner marked "ABS", that is, Pabs.

Table pressure means higher local atmospheres of pressure values generally do not make annotations, if necessary, in its lower-right corner marked "e", that is, Pe.

Vacuum is less than the local atmospheric pressure pressure (positive).

Difference between vacuum pressure means the pressure and atmospheric pressure (negative values). Vacuum pressure is numerically the same as vacuum, but should precede the value with a minus sign.

The relation between pressure, gauge pressure and vacuum pressure is: pressure = gauge pressure (vacuum) + local atmospheric pressure

A: what is the State of State standards and benchmarks?

Q: standard conditions refers to the temperature of 20 ℃, relative humidity of 65%, the State of the air pressure is 0.1MPa. Under standard conditions, the air density is 1.185kg/m^3, according to ISO8778, under standard conditions, after units can be labeled "(ANR)", such as 30m^3/h (ANR).

Benchmark status refers to the temperature of 0 ° c, dry air of pressure 101.3kPa. The air density under the reference state for the 1.293kg/m^3.
