이물질 섭취: Bolts, nuts, welding slag, or hardened material lumps enter the valve and wedge between the rotor and housing. Install a magnetic separator or inline screen upstream. 물체를 추출하려면 엔드 플레이트를 제거하십시오.
Bearings fail due to contamination or lack of lubrication. 베어링과 씰을 교체하십시오. Upgrade to outboard bearings with triple lip seals and air purge if the environment is dusty.
문제 2: 과도한 공기 누출
가능한 원인 및 해결 방법:
Abrasive materials wear down the rotor edges increasing clearance. 필러 게이지로 여유 공간을 검사합니다. For adjustable tip rotors, advance the tips. For fixed rotors, replace the rotor or install a new wear sleeve.
부적절한 설치 정렬:
잘못된 회전 방향:
과도한 차압:
문제 3: 베어링 과열
가능한 원인 및 해결 방법:
오염된 윤활유:
Coupling misalignment in direct drive units creates radial loads on bearings. Realign the motor and valve shafts. 손상된 커플링을 교체하십시오.
예. Doebritz engineers provide remote diagnostic support via video call and detailed maintenance manuals with exploded views and part numbers for all powder rotary valves.
