QInstallation position verification method for assembled ECS systems
Simulate manual docking with no air pressure and power supply. Smooth full insertion without obvious jamming confirms accurate positioning within floating tolerance range.

QLubrication requirement for positioning pins and sleeves
Proper special lubricating grease must be applied on matching surfaces during initial installation and regular maintenance to reduce dry friction and extend service life.

QAnti-reverse foolproof design of QCM module assembly
Special clamping grooves and direction marks are reserved on modules and mounting frames to ensure unidirectional assembly, avoiding short circuit and equipment damage caused by reversed power poles or signal lines.

QFluid cleanliness requirements before connecting MTC/QCB/QCT/QCH couplings
Install filters no less than 100-mesh on all pipelines to remove impurities, preventing valve core jamming and sealing surface scratch damage.

QConsequences of undersized driving cylinders
Insufficient thrust fails to realize full fitting, resulting in air leakage, blocked fluid circulation and poor signal contact. Connectors may even pop open instantly after pressure boosting.

QWeekly preventive maintenance items for ECS systems
-Check foreign matters and consistent height of signal pins
-Inspect air leakage at fitting positions by hand touch
-Clean sundries on docking surfaces
-Check abnormal gaps after full connection

QCommon causes for ECS docking jamming failure
Long-term operation leads to structural displacement exceeding ±2mm floating compensation range. Solution: recalibrate installation positions of cylinders and fixtures.
