Compressor air is an auxiliary aircraft that can produce pressurized air to get
attention and intensive care and continue,so that the compressor can operate
smoothly and hold in a long periode of time.if the compressor has decreased the
compression pressure it will be make chargingwind come late on the bottle and it
will have an impact on the leangth of the parent machine motion,though this is
very decrease in compression pressure in the air compressor is heppening because
of the wear on the piston ring (ring piston),lack of care lube oil (lubricating
oil),leaks in the suction valve and tap,dirty water cooler (air conditioning),damage
to the onion oil scraper (oil sealing ring).
Factor causing the decline in the compression pressure in the compressor is
due to wear on the piston ring ,lack of care lube oil (lubricating oil),leak in the
suction valve and tap, dirty water cooler (air conditioning),damage to the onion oil
scraper (ring sealing oil),water filter breakdown,the brakdown of cooling water
filter and most dangerous components of the compression pressure reductionis
piston ring, suction and pressure valve ,oil scrape ring,tube and filter water
cooling recevoir.
