FAW J6P واقي المروحة: تفكيك 46 الأجزاء المهمة للتحكم في تدفق الهواء بشكل لا تشوبه شائبة

This is an expert technical deconstruction of the FAW J6P واقي المروحة (also known as the ‘Fan shroud’, شركات 2) and its 45-part mounting assembly from Chapter 37. This system is critical to the thermal management of the FAW Jiefang CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. This component is not a simple “يحمي”; it is an “المنطق الديناميكي الهوائي” أداة.

ال FAW J6P واقي المروحة يخلق أ “vacuum tunnel,” forcing the engine fan (see Chapter 20) to pull 100% of its air *through* the ‘Radiator assy’ (شركات 1). بدون هذا الكفن, a fan is extremely inefficient, pulling air from the “path of least resistance” (the sides) و “stalling.” هذا “Airflow Funnel Logic” is the difference between peak cooling and catastrophic overheating.

This guide is essential for fleet technicians and parts specialists. ال FAW J6P واقي المروحة is made of a composite polymer, ولها #1 enemy is vibration, which causes fatigue cracks. We will deconstruct the entire 46-part system, focusing on the “منطق تدفق الهواء” (the guard itself), ال “Heat Exchange Context” (the radiator it serves), و “المنطق المضاد للاهتزاز” (the complex web of brackets, tie-rods, and fasteners that protect it).

جوهر 1: ال “Airflow Funnel” منطق (عنصر 2)

هذا المكون هو “hero” of this assembly. All other 45 parts are in service to this component’s function.

1. عنصر: ‘Fan shroud’ (1309010-14ب)
هذا (شركات 2) *is* the FAW J6P واقي المروحة. إنه “المنطق الديناميكي الهوائي” is more complex than it appears. It is not a simple “صندوق” أو “guard.” It is an engineered “shroud” أو “tunnel” designed to optimize airflow.

ال “Tip Clearance Logic” is the most critical design element. This refers to the *tiny, precise gap* between the ends of the fan blades and the inner “tunnel” التابع FAW J6P واقي المروحة. If this gap is too large, هواء “recirculates” from the high-pressure side back to the low-pressure side, “المماطلة” the fan and destroying its efficiency.

هذا “Vacuum Logic” هو غرضه كله. ال FAW J6P واقي المروحة يخلق أ “مختوم” بيئة, forcing the fan to pull a “فارغ” *across the entire surface area* of the ‘Radiator assy’ (شركات 1) زعانف. This ensures even cooling and prevents “hot spots.”

“المنطق المادي” هو أيضا المفتاح. This part is made from a “البوليمر المقوى بالزجاج” (a composite). It must be lightweight, but also rigid enough to not “flex” أو “warp” from the 100°C+ heat radiating off the engine. It must also absorb constant, اهتزاز عالي التردد.

ال “Failure Mode Logic” يكون “fatigue cracking.” A heavy-duty truck chassis flexes constantly. This vibration is the #1 enemy of the FAW J6P واقي المروحة. A small crack, starting from a mounting bolt, سوف “العنكبوت” across the shroud, breaking the “vacuum seal” and causing an immediate, drastic loss in cooling performance.

جوهر 2: ال “التبادل الحراري” سياق (عنصر 1)

ال FAW J6P واقي المروحة is useless without the component it is designed to “serve”: the ‘Radiator assy’.

1. عنصر: "المشعاع عاصي."’ (1301010-14ب)
هذا (شركات 1) هو “Heat Exchange Logic.” إنها كبيرة, سلبي “تقليل الحرارة” for both the engine coolant and the turbocharger’s “شحن الهواء” (via the intercooler). ك “سلبي” جهاز, it relies 100% on *airflow* to dissipate heat.

ال “Symbiotic Logic” is that the FAW J6P واقي المروحة (شركات 2) is *mounted directly* to the frame of the ‘Radiator assy’ (شركات 1). Its design “الأختام” it against the radiator’s edges. هذا “Matched Set Logic” ensures that any air pulled by the fan *must* first pass *through* the radiator’s fins.

The survival of the FAW J6P واقي المروحة is therefore directly “tied” to the survival of the radiator. The radiator provides the “mounting-face” و “structural support” for the fan shroud.

جوهر 3: ال “المضادة للاهتزاز” منطق التركيب (The Guard’s Life Support)

This group represents the complex “Vibration Isolation Logic.” منذ FAW J6P واقي المروحة يكون (هش) composite and the chassis/engine (تهتز) is steel, this system is what prevents the FAW J6P واقي المروحة من “اهتزاز” itself to pieces.

1. ال “منطق العزلة” (عناصر 11, 12, 13)
The entire ‘Radiator assy’ (which holds the fan guard) sits on a ‘Radiator bottom crossmember assy’ (1302030-61ب). هذا “الرف” is held by the ‘Radiator left support’ (1302027-70ش) و ‘Radiator right support’ (1302028-70ش). هؤلاء “يدعم” use large rubber “isolator” البطانات (see Chapter 38) ل “damp” the raw vibration from the frame.

2. ال “Anti-Sway Logic” (عناصر 18, 19)
هذا هو “Shearing Force Logic” حماية. ال ‘Tie rod assy’ (1302050-01) و ‘Tie rod upper support’ (1302041-14ب) are diagonal stabilizers. When the truck hits a pothole, the chassis “flexes.” These tie rods prevent the radiator and the attached FAW J6P واقي المروحة من الوجود “twisted” أو “swayed,” which would cause an instant “fatigue crack.”

3. ال “Frame Logic” (عناصر 8, 22, 26, 33, 35)
هذا “web” of steel (‘Radiator connecting plate’ (1301020-61ب), ‘Radiator support plate’ (1302040-14ب), إلخ.) هو “Structural Logic.” It creates a “rigid cage” around the “isolated” المشعاع, providing the secure mounting points for the FAW J6P واقي المروحة.

جوهر 4: ال “System Integration” منطق (SSU & السباكة)

This final group includes all “أصغر الوحدات القابلة للخدمة” (SSU) و “السباكة” that must co-exist with the FAW J6P واقي المروحة.

1. ال “المنطق السحابي” (البراغي, المكسرات, غسالات)
This includes all “Hardware Logic,” مثل "مسمار شفة مسدس."’ (س1840816, Q1841230, إلخ.), "الترباس المختلط."’ (CQ1460820), و ‘Hexagon nuts’ (CQ34010, CQ34008, إلخ.). هذه هي “Vibration-Proof Logic” السحابات.

A single loose bolt (على سبيل المثال, شركات 7, which holds the FAW J6P واقي المروحة‘s support plate) سيتم إنشاء “vibration hot spot” و “hammer” the composite shroud until it cracks. This is why high-tensile, “ذات حواف” (القفل الذاتي) hardware is essential.

2. ال “Plumbing Logic” (خراطيم & المشابك)
This group includes all the hoses ("خرطوم مدخل الرادياتير."’ (1303011-14ب), "خرطوم مخرج الرادياتير."’ (1303021-14ب), إلخ.) and their high-torque ‘Banjo-type hose clamps’ (CQ67670B, إلخ.).

ال “منطق التوجيه” of this plumbing is designed *around* the FAW J6P واقي المروحة. The hoses must be “مرن” to absorb the vibration between the “محرك” و “المشعاع” حَشد. They are routed to clear the shroud and, والأهم من ذلك, ال “spinning” معجب (الفصل 20) *inside* the shroud.
