مروحة فاو J6P: تفكيك 10 الأجزاء المهمة لتبريد المحرك بشكل لا تشوبه شائبة

Welcome to this definitive technical deconstruction of the مروحة فاو J6P and fan clutch assembly. This guide provides an expert analysis of the complete fan system for the FAW Jiefang CA3250P66K2L1T1E 6×4 heavy-duty diesel dump truck. Engineered for professional technicians, مديري الأسطول, ومتخصصين في قطع الغيار, this document breaks down the entire 10-component assembly from its largest structural elements, such as the fan and clutch, to its smallest, yet critical, وحدات صالحة للخدمة, including every specialized fastener, غسالة, and flange.

The thermal management system on the CA3250P66K2L1T1E is designed for extreme, low-speed, high-load conditions. Unlike highway trucks, a dump truck operates at maximum engine power with minimal vehicle speed, resulting in zero هواء الكبش. In these scenarios, the engine’s survival is 100% dependent on the مروحة فاو J6P to mechanically pull thousands of cubic feet of air through the radiator, preventing catastrophic overheating.

جوهر 1: ال “حركة الهواء” منطق (The FAW J6P Fan)

تمثل هذه المجموعة عضلة من النظام. Its logic is straightforward: convert the rotational energy delivered by the clutch into a high-volume, high-velocity column of air. This is the primary job of the مروحة فاو J6P.

1. عنصر: "مروحة عاصي."’ (1308010-14ب)
هذا (شركات 4) هو "جمعية المعجبين".’ and is the most prominent component of the مروحة فاو J6P نظام. This is not a lightweight component; it is a heavy-duty, multi-blade unit, likely fabricated from high-strength, glass-reinforced composite or precision-stamped steel.

ال منطق الملعب بليد هي ميزة التصميم الأكثر أهمية. The specific angle, depth, انحناء, and number of blades are not arbitrary. They are the result of extensive fluid dynamics engineering to find the “sweet spot” that maximizes airflow (تقاس في CFM), while simultaneously minimizing noise and the horsepower required to spin it (السحب الطفيلي).

ال منطق التجميع is a crucial service consideration. The part is designated ‘Fan assy’ (حَشد), which signifies it is a single, factory-balanced, non-serviceable component. The blades are permanently affixed to a central hub, as the entire مروحة فاو J6P unit is dynamically balanced to extremely tight tolerances.

At high rotational speeds, even a minor imbalance—such as from a small crack or a bent blade—would induce destructive, high-frequency vibrations. These vibrations would lead to the rapid failure of the ‘Fan clutch assy’ (شركات 8) المحامل. For this critical safety reason, if any part of the fan blade is damaged, the *entire* ‘Fan assy’ (شركات 4) يجب استبداله.

جوهر 2: ال “المشاركة الذكية” منطق (قابض المروحة FAW J6P)

تمثل هذه المجموعة مخ من النظام. Its entire purpose is to intelligently decouple the fan from the engine’s drive pulley, ensuring the fan only spins when it is absolutely needed. هذا هو “ذكي” جزء من مروحة فاو J6P.

1. عنصر: 'مروحة القابض عاصي’ (1313010-65د)
هذا (شركات 8) is the ‘Fan Clutch Assembly’, the most complex and vital component in this group. For a heavy-duty application like this, إنه أ القابض اللزج, the heart of the مروحة فاو J6Pمنطق.

ال المنطق اللزج is a marvel of non-electric, thermomechanical engineering. Mounted on the front of the clutch is a bi-metallic thermostatic spring. This spring is positioned directly in the airstream *after* it has passed through the radiator. Its ‘logic’ is to read the temperature of the air coming *off* the radiator, which is a direct proxy for coolant temperature.

كما ترتفع درجة حرارة الهواء (على سبيل المثال, فوق 85 درجة مئوية), تتوسع معادن الربيع بمعدلات مختلفة, causing it to coil. تفتح هذه الحركة الجسدية ميكانيكيًا صمامًا داخليًا صغيرًا. This valve releases a specialized, high-viscosity silicone fluid from a storage reservoir into a غرفة العمل. تحتوي هذه الغرفة على معقدة, alternating plates—one set connected to the input shaft and the other to the output body (which holds the مروحة فاو J6P).

ال قص السوائل of this thick fluid between the spinning plates transfers torque. كلما كان الهواء أكثر سخونة, كلما فتح الصمام, the more fluid enters, وكلما زادت سرعة دوران المروحة. هذا هو Progressive Engagement Logic; it is not a simple on/off switch. It allows the مروحة فاو J6P to spin at a variable speed, precisely matching the engine’s real-time cooling demands. When the radiator air cools, الربيع يغلق الصمام, the fluid is pumped back to the reservoir, وتنفصل المروحة.

2. عنصر: 'شفة انتقال قابض المروحة’ (1313063-14ب)
هذا (شركات 10) is the critical Interface Logic عنصر, or adapter flange. The ‘Fan clutch assy’ (شركات 8) هي وحدة متخصصة, but the engine’s pulley hub has its own standardized bolt pattern.

هذه "شفة الانتقال".’ is the essential, high-strength steel adapter that bridges the gap. تم تصنيعه بدقة ليتم تثبيته بشكل مسطح على محور بكرة المحرك (using ‘Combination bolts’, شركات 9) and provide the exact mounting face required by the ‘Fan clutch assy’. It must transfer 100% of the drive torque and maintain perfect concentricity to prevent vibration in the مروحة فاو J6P حَشد.

جوهر 3: ال “تصاعد & قفل” منطق (Securing the FAW J6P Fan)

This final group contains all the serviceable hardware. It is the most frequently overlooked yet is absolutely critical for safety. إنه منطق is to manage three primary forces: high rotational torque, constant engine vibration, والدراجات الحرارية. Using generic, non-specified hardware for a مروحة فاو J6P يمكن أن يؤدي إلى فشل كارثي, where the fan assembly can detach while the engine is running.

1. ال “مروحة إلى القابض” مجموعة (شركات 1, 2, 3)
يتضمن هذا التجميع الفرعي: "الجوز السداسي."’ (CQ34008, الكمية 6), "غسالة الربيع."’ (س40308, الكمية 6), و "الغسالة".’ (Q40108, الكمية 6). هذا هو منطق ساندويتش تستخدم لتركيب "مروحة آسى".’ (شركات 4) onto the front of the ‘Fan clutch assy’ (شركات 8), a critical joint for the مروحة فاو J6P.

ال غسالة (شركات 3) هي "غسالة مسطحة".,’ توفير واسعة, flat surface area. Its logic is to distribute the clamping load of the nut and prevent it from pulling through the fan’s composite or steel mounting holes. ال غسالة الربيع (شركات 2) هو الجزء الأكثر أهمية. It is a high-tension lock washer providing تحميل مسبق مضاد للاهتزاز; it actively pushes against the nut, maintaining tension and preventing it from backing off under constant, اهتزاز عالي التردد.

2. ال “القابض إلى شفة” مجموعة (شركات 5, 6, 7)
تشمل هذه المجموعة: "مسمار الترباس."’ (CQ1201030, الكمية 4), "غسالة الربيع."’ (س40310, الكمية 4), و "الجوز السداسي."’ (CQ34010, الكمية 4). هذا هو منطق جبل صالح للخدمة. "مسامير التثبيت".’ (شركات 5) are likely threaded permanently into the ‘Fan clutch assy’ (شركات 8) نفسها.

This design is intentional. It allows a technician to easily ‘hang’ مجموعة القابض الثقيلة على الأزرار, which protrude through the ‘Transition flange’ (شركات 10). This holds the component in place, freeing the technician’s hands to easily install the ‘Spring washers’ (شركات 6) and ‘Hexagon nuts’ (شركات 7) without having to align bolt holes while supporting the component’s full weight. This design is crucial for field serviceability for the مروحة فاو J6P.

3. ال “شفة إلى المحرك” مجموعة (شركات 9)
تشمل هذه المجموعة: "الترباس المختلط."’ (CQ1421040, الكمية 6). هذا هو منطق خط التجميع. "الترباس المختلط".’ (or ‘combi-bolt’) is a specialized fastener that has a captive, free-spinning washer (in this case, a spring washer) pre-installed on the bolt.

This feature is crucial for both the factory and field service. It makes installation faster (one part, not two) and makes it *impossible* to forget or drop the all-important spring washer. These six bolts secure the ‘Transition flange’ (شركات 10) إلى محور بكرة المحرك, نقل 100% of the drive power from the belt to the entire مروحة فاو J6P نظام.
