Starting from now, in order to enhance communication among users, a 【Daily Question】 activity has been launched on the Mechanical Equipment Technology forum. We hope everyone will participate actively to progress and improve together! ! ! Rewards: 3 wealth points for active participation, 10-15 wealth points for correct answers. This question is valid for two days; no score will be given after that period. How should spare screw compressor heads in the warehouse be stored over the long term? Normally, the compressor is sealed, a layer of oil film is applied to its internal mechanical parts, and then some nitrogen is injected to maintain pressure before it is stored. ============================== High-quality promotions: Mechanical equipment——Maintenance procedures for York screw compressors https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1806833 Mechanical equipment——Upgrading of York Quinton control centers https://bbs.hcbbs.com/thread-1804837-1-1.html Mechanical equipment——Major repairs for GEA Grasso screw compressors https://bbs.hcbbs.com/thread-1800467-1-1.html Mechanical equipment——Disassembly and maintenance of British HOWDEN screw compressors https://bbs.hcbbs.com/thread-1832529-1-1.html Mechanical equipment——Disassembly and maintenance of Japanese Maekawa MYCOM screw compressors https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=
1) Seal all openings to prevent moisture and dust from entering. 2) Replace the lubricating oil before shutdown and run the machine for 30 minutes; then drain the condensed water from the air tank and oil cooler after two or three days. 3) Completely drain the condensate water. 4) Move the machine to a place with little dust and dry air for storage whenever possible.
1) Seal all openings to prevent moisture from entering； 2) Wrap the safety valve and control panel with oilpaper to prevent rusting ； 3) Before shutting down, replace the lubricating oil and run the machine for 30 minutes; two days later, drain the condensed water from the oil-gas tank and the cooler ；
Secure and seal it properly, and store it in a dry, dust-free place.

1) Seal all openings to prevent moisture from entering； 2) Wrap the safety valve and control panel with oilpaper to prevent rusting ； 3) Cover with colored striped fabric to prevent dust, rain, and water. 4) Elevate with sleepers to prevent low-lying areas from being flooded during the rainy season. 5) Regularly check the condition.
If possible, place the compressor head in a dedicated storage box and stand the box upright, that is, position the compressor head vertically with proper support. An inert gas is also introduced into the dedicated storage box to prevent air from entering and causing oxidation of the equipment.
