Типовые неисправности по технологиям
Цель: Изучить тему «Типовые неисправности по технологиям» и закрепить её практическими заданиями и самопроверкой.
2 акад. часа чтение и разбор теории, решение задач, работа со схемой или виртуальным стендом и проверка понимания.
Основной материал
Pressure: plugged impulse, leaks, wrong manifold, trapped gas/liquid, drift. Temperature: broken sensor, polarity, lead resistance, CJC, poor insertion. Level: false echo, build-up, density change, wrong geometry. Flow: empty pipe, grounding, two-phase, wrong straight run, square-root error. Valve: stiction, air leak, positioner calibration.
Symptom database
Maintenance team benefits from structured symptom-cause-action knowledge base. But every failure must still be verified; same symptom can have multiple causes.
Практическая работа
Create table 20 rows: symptom, possible causes, diagnostic checks, corrective action, evidence required.
Самопроверка
• Name two pressure faults.
• Two temperature faults.
• Two level faults.
• Two flow faults.
• Two valve faults.
