BALDOR AIR COMPRESSOR
Chapter Five: Pipeline Configuration And
Installation
a. pipeline installing requirements
The machine air-supply port with screw thread adapter can connect with air-supply pipeline. Please refer
to the product appearance size when install.
1. When checking and maintenance, in order not to affect the overall or other machines work and
prevent air from flowing back, the stop valve should be installed between the machine and the storage
tank, and safety valve should be installed in the air storage tank.
2. Branch pipeline must connect from the top of the main line to avoid the condensed water flow back to
the compressor.
3. Shorten the pipeline and be straight linear delivery around the whole factory to reduce the bend and
all kinds of valve in order to reduce the pressure loss.
b. the general principles of the pipeline system
The pipeline system of compressing air should meet the users’ needs: compressed air flow rate,
pressure and air quality. And also determined from the other aspects: reliable air supply, saving energy,
reducing the investment, easy maintenance, etc. Specifically as below:
1. Consider from the pressure requirements
a、 Pipeline system designed accord to meeting the customers’ needs of highest pressure. The other need
low pressure can install depressurized device on the local. Generally, common pressure of factory is 0.6
M Pa and 0.3 M Pa. The pipeline can fill 0.6 M Pa rated pressure, but install depressurized valve
behind the 0.3 M Pa pressure branch line valve to meet the requirements of low pressure customers’
needs.
b 、 Pipeline system can be divided into several pressure classes according to user's pressure size,
combined with the workshop or equipment arrangement, etc. Supply air by the several pressure class
of pipeline system.
2． consider the air quality
a、Use an untreated compressing air pipeline system. A few users who have special requirements of
air quality can install small device of oil removing, drying, and purifying in local.
b 、 Design two pipeline systems in the factory or some districts. One is for conveying untreated
compressed air, other for conveying dried or oil-free compressed air.
3． consider from the characteristics of the load
Some air equipment use air very different in instantaneous maximum air volume(such as the forging
hammers which use compressor power, mechanical workshop which use air power sending sand, pump and
large model, etc.). In order not to affect other air equipment, generally
