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 ram air. 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 “Air Movement” منطق (The FAW J6P Fan)

This group represents the 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: ‘Fan assy’ (1308010-14ب)
هذا (شركات 4) is the ‘Fan Assembly’ 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 Blade Pitch Logic is its most critical design feature. 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 (measured in CFM), while simultaneously minimizing noise and the horsepower required to spin it (parasitic drag).

ال Assembly Logic 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) must be replaced.

جوهر 2: ال “Smart Engagement” منطق (The FAW J6P Fan Clutch)

This group represents the 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 “smart” جزء من مروحة فاو J6P.

1. عنصر: ‘Fan clutch assy’ (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, it is a Viscous Clutch, the heart of the مروحة فاو J6P‘s logic.

ال Viscous Logic 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.

As this air temperature rises (على سبيل المثال, above 85°C), the spring’s metals expand at different rates, causing it to coil. This physical movement mechanically opens a small internal valve. This valve releases a specialized, high-viscosity silicone fluid from a storage reservoir into a working chamber. This chamber contains intricate, alternating plates—one set connected to the input shaft and the other to the output body (which holds the مروحة فاو J6P).

ال fluid shear of this thick fluid between the spinning plates transfers torque. The hotter the air, the more the valve opens, the more fluid enters, and the faster the fan spins. 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, the spring closes the valve, the fluid is pumped back to the reservoir, and the fan disengages.

2. عنصر: ‘Fan clutch transition flange’ (1313063-14ب)
هذا (شركات 10) is the critical Interface Logic عنصر, or adapter flange. The ‘Fan clutch assy’ (شركات 8) is a specialized unit, but the engine’s pulley hub has its own standardized bolt pattern.

This ‘Transition Flange’ is the essential, high-strength steel adapter that bridges the gap. It is precisely machined to bolt flat against the engine’s pulley hub (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, and thermal cycling. Using generic, non-specified hardware for a مروحة فاو J6P can lead to catastrophic failure, where the fan assembly can detach while the engine is running.

1. ال “Fan-to-Clutch” مجموعة (شركات 1, 2, 3)
This sub-assembly includes: "الجوز السداسي."’ (CQ34008, الكمية 6), ‘Spring washer’ (س40308, الكمية 6), and ‘Washer’ (Q40108, الكمية 6). هذا هو Sandwich Logic used to mount the ‘Fan assy’ (شركات 4) onto the front of the ‘Fan clutch assy’ (شركات 8), a critical joint for the مروحة فاو J6P.

ال غسالة (شركات 3) is a ‘flat washer,’ providing a wide, 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) is the most critical part. It is a high-tension lock washer providing Anti-Vibration Pre-load; it actively pushes against the nut, maintaining tension and preventing it from backing off under constant, high-frequency vibration.

2. ال “Clutch-to-Flange” مجموعة (شركات 5, 6, 7)
This group includes: ‘Stud bolt’ (CQ1201030, الكمية 4), ‘Spring washer’ (س40310, الكمية 4), and ‘Hexagon nut’ (CQ34010, الكمية 4). هذا هو Serviceable Mount Logic. The ‘Stud bolts’ (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’ the heavy clutch assembly onto the studs, 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 “Flange-to-Engine” مجموعة (شركات 9)
This group includes: ‘Combination bolt’ (CQ1421040, الكمية 6). هذا هو Assembly Line Logic. A ‘combination bolt’ (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) to the engine’s pulley hub, transferring 100% of the drive power from the belt to the entire مروحة فاو J6P نظام.
