Suggestions on piping works
The unsuitable piping works done to the compressor could cause abnormal vibration and noise that might damage the compressor.
Take notice of the following pointers to prevent this situation from happening:
1. Cleanliness of the system should be kept after welding the piping to avoid any swarf or debris contained inside the system as it
may cause serious damage to the compressor during operation.
2. In order to reduce the vibration on the piping tubes, it is recommended to use copper tube to be the suction and discharge piping
tubes. Copper tubes are better to minimize the vibration in the piping while the compressor is in operation. In case steel tubes are
used in piping system, the suitable welding works are very important to avoid any stress in the piping. This inner stress can cause
harmonic vibration and noise that can reduce the life of the compressor. If a large-caliber copper tube is not easily accessible and a
steel tube is used instead in suction port, Hanbell also recommends the use of a copper tube in discharge port to best minimize
abnormal vibration and noise.
3. Remove the oxidized impurities, swarf or debris caused by welding in the piping tubes. If these materials fall into the
compressor, the oil filter might be clogged and result in the malfunction of lubrication system, bearings and capacity control
system.
4. The material of suction and discharge flange bushing is forged steel and it can be welded directly with piping connectors. After
welding the flange bushing and pipes, it must be cooled down by ambient air. Do not use water to cool it down because water
quenching is prohibited.
Installing the compressor in a sloping position
Figure 4.4 shows a 15° limit of oblique angle for installation of compressor. In case the oblique angle is higher than the limit,
compressor will be shut down easily. For special applications like the installation in ships, fishing boats, etc…, where the oblique
angle might exceed the limit, external oil separators, oil tanks and related accessories are recommended to be installed. Please
contact HANBELL or local distributors for further layout recommendation.
