TAILIEUCHUNG - GasTurbine Engineering HandbookSecond Edition phần 10

Việc khởi động và tắt máy của một tuabin khí điển hình được thể hiện trong hình 19-5 và 19-6. Thời gian và tỷ lệ phần trăm là những giá trị gần đúng và sẽ thay đổi phụ thuộc vào thiết kế tuabin. Tuabin khí trong quá trình khởi động trên một ổ đĩa phụ trợ, ban đầu nó là Â mang đến một tốc độ khoảng 1200 ± 1500 RPM | Maintenance Techniques 723 Combining the practice of preventive maintenance and total quality control and total employee involvement results in an innovative system for equipment maintenance that optimizes effectiveness eliminates breakdowns and promotes autonomous operator maintenance through day-to-day activities. This concept known as Total Productive Maintenance TPM was conceived by Seiichi Nakajima and is well-documented in his book Introduction of TPM and is highly recommended reading for all involved in the maintenance area. A new maintenance system is introduced based on the new mantra for the selection of all equipment Life Cycle Cost. This new system especially for major power plants is based on the combination of total condition monitoring and the maintenance principles of total productive maintenance and is called the Performance Based Total Productive Maintenance System. The general maintenance system is fragmented and can be classified into many maintenance concepts. The following are five P s of maintenance for major power plants petro-chemical corporations and other process type industries leading to the ultimate maintenance system 1. Panic maintenance based on breakdowns 2. Preventive maintenance 3. Performance based maintenance 4. Performance productive maintenance 5. Performance based total productive maintenance PTPM . Performance based total productive maintenance consists of the following elements 1. Performance based total productive maintenance aims to maximize equipment efficiency and time between overhaul overall performance effectiveness 2. Performance based total productive maintenance aims to maximize equipment effectiveness overall effectiveness 3. Performance based total productive maintenance establishes a thorough system of PM for the equipment s entire life span. 4. Performance based total productive maintenance is implemented by various departments engineering operations maintenance . 5. Performance based total productive .
