قضيب صدم للكسارة الصدمية
Identify parts for Metso impact crushers, check models and drawing numbers, confirm materials and processes, and submit an inquiry.
المعدات, Models and Drawing References
Identify the installed machine model and key dimensions, then check the part number, drawing number, drawing revision and physical interfaces.
Models and Key Dimensions
Metso Nordberg NP13/NP15/NP20/NP1110/NP1213/NP1313/NP1315/NP1415/NP1520/NP1620/NP2023
Drawing Number / Part Number
Provide the equipment nameplate, complete model and existing part number so that the installation position and drawings can be checked.
Drawing Revision
Confirm dimensions by measuring the sample or using the customer drawing. Cross-check the drawing revision against the model on the equipment nameplate.
المواد والعمليات
Select the material grade and heat treatment for the operating conditions, processed material and equipment specifications. The options below are commonly used; confirm the final grade against the drawing and technical agreement.
Cr26 high-chromium cast iron (600-700 HB)
Select materials to suit OEM specifications and operating conditions; confirm the final grade and heat treatment against the drawing.
Martensitic Wear-Resistant Steel (450-550 HBW)
Select materials to suit OEM specifications and operating conditions; confirm the final grade and heat treatment against the drawing.
Ceramic MMC composite (60-65 HRC)
Select materials to suit OEM specifications and operating conditions; confirm the final grade and heat treatment against the drawing.
High-فولاذ المنغنيز Mn18Cr2 (220-240 HB)
Select materials to suit OEM specifications and operating conditions; confirm the final grade and heat treatment against the drawing.
Wear and Replacement Criteria
Common wear patterns and maintenance guidance are outlined below. Determine replacement intervals from operating conditions, processed material and equipment performance data.
Common Wear Patterns
- High-velocity material impact wears and rounds the ends
- Impact initiates microcracks and drives their growth
- Abrasion produces surface grooves
- Ceramic inserts detach or fracture
Replacement Criteria
Assess the remaining blow bar section, cracks, ceramic insert condition and fastening against the maintenance requirements for the model. Replace immediately if a through-crack is found. Match replacement weights and maintain rotor balance as specified by the OEM.
Materials and Process Control
تعتمد متطلبات المواد والمعالجة الحرارية والتركيبات المركبة والفحص على الرسم المحدد وظروف التشغيل والمراجعة الفنية.
Material Grade / Substrate
Cr26 high-chromium cast iron (600-700 HB) / martensitic wear-resistant steel (450-550 HBW) / ceramic MMC composite (60-65 HRC) / Mn18Cr2 high-manganese steel (220-240 HB)
Heat Treatment Condition
اتبع المعيار المطبق لدرجة المادة؛ وأكِّد متطلبات المعالجة الحرارية والصلادة وفقًا للرسم.
Composite / Hardfacing Requirements
اتبع متطلبات التصميم لدى الشركة المصنعة الأصلية؛ وأكِّد أي لحام تقوية (Hardfacing) أو تركيب مركب وفقًا للرسم.
Dimensions and Inspection
افحص الأبعاد الرئيسية وفقًا للرسم الخاص برقم قطعة الشركة المصنعة الأصلية. تحقق من أسطح التركيب والإحكام كلٌّ على حدة، ونفّذ اختبار UT/MT غير المتلف على المسبوكات.
قد لا تكون الأجزاء التي تحمل الاسم نفسه قابلة للتبادل بسبب اختلاف طراز الماكينة أو مراجعة الرسم أو واجهة التركيب أو مواصفات المادة. يُرجى استخدام الطراز الكامل والرقم التسلسلي ورقم الرسم والرسم قبل التصنيع.
