BALDOR AIR COMPRESSOR
d. the connection and arrangement of air pipeline
1、
Generally should use welding connect the air pipeline, but should use the corresponding
flange or screw threaded connection in the joint of equipment and valve. The section which is
often removed, should use screw threaded connection when the pipe diameter is less than or equal
to DN25, and use flange connection when more than DN25.
2、
In order to facilitate discharging oil-water out of the pipe when delivering the undried and
unpurified compressed air through the pipeline, there should be more than 2/1000 slope in the
pipe line, no draining valve (plug) in the low place, few turning and short straight, few valves as
soon as possible.
3、 The top of underground pipeline is covered no less than 0.7 m. It is not limited to
dried and purified air compressor pipe.
4、
The installation position and surface size of the pressure and flow instrument should be
seeing the indicated pressure clearly by the operator. The pressure scale range should make
working pressure on the 1/2 ~ 2/3 of dial.
5、
There should be take pressure strength and tightness test, unfavorable for hydraulic
pressure test after installing the system. It is qualified via test with the same air of 1.05 ~ 1.5 times
pressure if no leakage,
There are different choices according to the degree of drying and purifying compressed air which
the customer requires. According to the using condition of equipment, choose post-processing
devices: storage tank, drying machine, precision filter, and etc. best configuration should be:
air-water separator + storage tank+ pre-filter + drying machine + precision filter.
6、
Storage tank belongs to pressure vessel. There should be complete safety accessories: the
safety valve, pressure instrument, drain valve etc. Should keep record in the local labor
department and inspect it routinely every year.

a check before start for the first time
1、
Check the lubricating oil volume in the oil-air separator. Make sure the oil surface is better
above the middle of the oil-level table's upper limit and lower limit after normal operation.
2、
Electrical wiring and grounding line has been connected, and conform to the safety standard.
3、
Make sure supply air pipeline dredges, and all bolts, connectors are tighten.
4、
Check whether the motor power, voltage and
ensure the compressor start with no-load.
