قابض المروحة FAW J6P: تفكيك 10 الأجزاء الحاسمة للمنطق الحراري الذي لا تشوبه شائبة

مرحبا بكم في هذا التفكيك الخبير لل قابض المروحة FAW J6P حَشد, a critical component group for the FAW Jiefang CA3250P66K2L1T1E 6×4 diesel dump truck. This technical guide is engineered for service technicians, مديري الأسطول, ومتخصصين في قطع الغيار. We will deconstruct the entire 10-component “منطق” group, breaking it down from the primary ‘Fan clutch assy’ to its smallest serviceable fasteners, providing a complete picture for diagnostics and maintenance.

The thermal management of the CA3250P66K2L1T1E is defined by this “smart” عنصر. ال قابض المروحة FAW J6P هو “مخ” of the entire cooling fan system. Its sole logic is to intelligently engage the fan *only* when needed, saving fuel and horsepower, while ensuring the engine is perfectly protected under high-load, low-speed conditions.

جوهر 1: ال “Smart Engagement” منطق (The FAW J6P Fan Clutch)

This group represents the مخ of the entire cooling fan assembly. Its purpose is to intelligently and mechanically “decide” when to engage the fan, saving fuel, and when to lock it up for maximum cooling. This is the core logic of the قابض المروحة FAW J6P.

1. عنصر: ‘Fan clutch assy’ (1313010-65د)
هذا (شركات 8) is the ‘Fan Clutch Assembly’ نفسها, the most critical and complex component in this breakdown. For this heavy-duty application, it is a Viscous Clutch. This is a non-electric, thermomechanical device.

ال Thermostatic Logic is how it “thinks.” A bi-metallic thermostatic spring is mounted on the very front of the قابض المروحة FAW J6P. It sits directly in the air-path *after* the air has passed through the radiator. This allows it to read the true temperature of the cooling system.

As this air temperature rises (على سبيل المثال, above 85°C), the spring’s metals expand at different rates, causing it to coil or uncoil. This physical movement mechanically opens a small internal valve. هذا هو Viscous Logic.

Opening this valve allows a special, high-viscosity silicone fluid, stored in a reservoir, to flow into a working chamber. This chamber contains intricate, alternating plates and fins—one set connected to the input shaft (driven by the engine pulley) and the other to the output body (which holds the fan).

ال Fluid Shear Logic is what transfers power. ال “shear” of this thick fluid between the spinning plates is what transfers torque from the engine to the fan. The hotter the air, the more the valve opens, the more fluid enters the chamber, and the faster the fan spins. هذا هو Progressive Engagement, not a simple on/off switch. This variable-speed capability is the key feature of the قابض المروحة FAW J6P.

When the engine cools, the air from the radiator cools, the spring closes the valve, and an internal pump returns the fluid to the reservoir. This disengages the قابض المروحة FAW J6P, allowing the fan to freewheel, saving horsepower and significantly improving fuel economy.

جوهر 2: ال “Interface & يقود” منطق (The Flange)

This group contains the critical adapter that connects the قابض المروحة FAW J6P to the engine’s drive pulley. Its logic is to provide a secure, perfectly aligned mounting point and transfer 100% of the engine’s torque to the clutch.

1. عنصر: ‘Fan clutch transition flange’ (1313063-14ب)
هذا (شركات 10) is the ‘Fan Clutch Transition Flange.’ It is the essential “Interface” عنصر. ال قابض المروحة FAW J6P (شركات 8) is a specialized unit, but the engine’s pulley hub (often on the water pump) has its own standardized bolt pattern.

This ‘Transition Flange’ is the high-strength steel adapter that bridges this gap. It is precisely machined to bolt flat against the engine’s pulley hub (using the ‘Combination bolts’, شركات 9) و, بدوره, provide the exact mounting face and bolt pattern required by the قابض المروحة FAW J6P.

ال Concentricity Logic is its hidden, vital function. This flange must maintain perfect concentricity (zero “wobble” أو “runout”). Any misalignment would introduce destructive vibrations into the entire assembly, leading to premature failure of the قابض المروحة FAW J6P المحامل.

جوهر 3: ال “Driven Component” منطق (مجموعة المروحة)

This group represents the “حمولة” أن قابض المروحة FAW J6P is responsible for driving. Its logic is to convert the rotational energy it receives from the clutch into massive, high-velocity airflow.

1. عنصر: ‘Fan assy’ (1308010-14ب)
هذا (شركات 4) is the ‘Fan Assembly’ نفسها. While not technically part of the قابض المروحة FAW J6P, it is the component the clutch drives. It is a heavy-duty, multi-blade unit made from high-strength composite or steel.

ال Blade Pitch Logic أمر بالغ الأهمية: the specific angle and curvature of the blades are engineered to maximize airflow (CFM) while minimizing noise and the horsepower “drag” on the قابض المروحة FAW J6P.

ال Assembly Logic is a crucial service note: the ‘Fan assy’ is a single, factory-balanced component. It must be replaced as a whole if damaged. A bent blade will cause vibrations that will destroy the new قابض المروحة FAW J6P it is attached to.

جوهر 4: ال “Critical Fastener” منطق (All Hardware)

This final group is the most frequently overlooked. إنه منطق is to manage extreme vibration, عزم دوران عالي, and thermal cycling. Using generic hardware on a قابض المروحة FAW J6P assembly is a direct cause of catastrophic failure.

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

ال غسالة (شركات 3) is a ‘flat washer,’ providing a wide surface to prevent cracking the fan material. ال غسالة الربيع (شركات 2) is the most critical part, as it provides Anti-Vibration Pre-load, preventing the nuts from backing off under 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 for attaching the قابض المروحة FAW J6P (شركات 8) to the ‘Transition flange’ (شركات 10).

The ‘Stud bolts’ (شركات 5) are likely threaded permanently into the قابض المروحة FAW J6P نفسها. This allows a technician to easily ‘hang’ the heavy clutch assembly onto the studs, freeing their hands to install the washers and nuts.

3. ال “Flange-to-Engine” مجموعة (شركات 9)
This group includes: ‘Combination bolt’ (CQ1421040, الكمية 6). هذا هو Assembly Line Logic. A ‘combination bolt’ has a captive, free-spinning spring washer pre-installed. This feature makes installation faster and, والأهم من ذلك, makes it *impossible* to forget the critical spring washer. These bolts secure the ‘Transition flange’ (شركات 10) to the engine’s pulley hub, transferring all drive power to the قابض المروحة FAW J6P.
