QTroubleshooting for air leakage of separated ECS pneumatic modules
Leakage is mainly caused by aging sealing rings or damaged internal valve cores. Direct replacement of whole pneumatic joint assemblies is recommended instead of self-disassembly repair.

QFirst-step troubleshooting for offline ECS network modules
Dust accumulation causes increased pin contact impedance. Clean pins thoroughly with air blow guns or dedicated electronic contact cleaner first.

QFurther fault judgment if cleaning fails to restore network communication
Severe pin wear or internal wire breakage may occur. Replace complete network module assemblies in this case.

QSolutions for non-inductive cylinder retraction & full-fit sensors
Sensor displacement caused by long-term vibration is the main reason. Readjust and fasten sensor positions; replace physically damaged sensors directly.

QScale prevention measures for daily use of MTC temperature control couplings
Install pipeline filters in advance, add dedicated pipeline cleaning agents regularly to remove water scale, and apply anti-aging lubricant on sealing surfaces.

QMaintenance restrictions for leaking MTC couplings
Clean surface sand and iron scraps first. Internal sealing damage shall not be disassembled privately; contact QIAOTIAN professional technicians for replacement or factory maintenance to avoid damaging original sealing performance.

QMandatory replacement rules for expired ECS spare parts
Preventive replacement is required once reaching rated service life: fluid joints (300,000 cycles), positioning pins and sleeves (1,000,000 cycles). Potential internal fatigue damage may lead to sudden operational faults even without visible external damage.
