Ma’ruza 1 “Lokomotivlarga texnik xizmat ko`rsatish asoslari” faniga kirish Ma’ruza rejasi

Lokomotivning to’liq aylanmasi – bu lokomotivning asosiy deponing nazorat postiga chiqish vaqtidan boshlab, shu nazorat punktiga keyingi chiqishigacha bo’lgan vaqtga aytiladi.
Lokomotivlardan samarali foydalanishning axamiyatli ko’rsatkichlaridan biri bu poezdning og’irligidir. Temir yo’llarda xisobiy amallarni bajarishda yuk poezdlarining bir nechta og’irlik me’yorlaridan foydalaniladi: kritik, parallel, umumlashtirilgan, xisobiy va o’rtacha poezdning brutto oqirligi.
Tarkibning o’rtacha og’irligi – bu ko’rsatkich lokomotivning quvvatidan foydalanish samaradorligini baxolash imkonini beradi va uni shu uchastkaning o’zida va shu vaqtdagi sutka mobaynida bajarilgan tonna-kilometrlarni, lokomotivning poezd boshida bosib o’tgan masofasiga bo’lish orqali aniqlash mumkin.Quyidagilar xisobiga poezdning og’irligini oshirish mumkin:

• 
  Poyezdlarni haydashning rasional rejimlarini qo’llash;
  
• 
  To’liq tarkibli va to’liq og’irlikka ega bo’lmagan poezdlar sonini kamaytirish;
  
• 
  Poezdlar xarakatiga ta’sir etuvchi asosiy qarshilikni kamaytirish;
  
• 
  Poyezdlarning kinetik quvvatidan oqilona foydalanish;
  
• 
  Stansiyaning qabul qilib-jo’natish yo’llarini qayta ta’mirlash;
  
• 
  Yo’lning ishonchliligini oshirish va ogoxlantirishlarni kamaytirish;
  
• 
  Harakatni rasional tuzish va tashkil etish.
  

Nosoz lokomotivlar foyizi depo ta’mirlash bazasining xolatini va shu bilan birga lokomotivlarning ishonchlilik darajasini ko’rsatib beradi.
Nosoz lokomotivlarning foyizini kamaytirish quyidagicha ta’minlanadi:

• 
  Lokomotivlarning holatini yaxshilash orqali;
  
• 
  Ulardan foydalanish ishonchliligini oshirish orqali;
  
• 
  Ta’mirlashlarda turish vaqtlarini kamaytirish orqali;
