أنابيب فاو J6P: تفكيك 46 الأجزاء المهمة للتحكم الحراري المانع للتسرب

This is a complete technical analysis of the أنابيب فاو J6P نظام (الفصل 37), ال “arterial network” for the thermal management system on the FAW Jiefang CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. This 46-component group is not just a set of hoses; it is an engineered “Fluid & Air Transport Logic” نظام. Its integrity is paramount for preventing coolant leaks, boost leaks, and catastrophic engine overheating.

ال أنابيب فاو J6P system must simultaneously manage three “منطق السوائل” دوائر. ال “Primary Coolant Logic” (the main radiator hoses) moves high-temperature engine coolant. ال “Charge Air Logic” (the intercooler hose) transports high-pressure, hot air from the turbo. ال “Degassing Logic” (a network of small pipes) scavenges and removes destructive air bubbles from the system.

This guide is an essential resource for chassis technicians, مدراء صيانة الأسطول, ومتخصصين في قطع الغيار. We will deconstruct every component of the أنابيب فاو J6P حَشد. سنقوم بتحليل “Primary Circulation Logic” (the main coolant hoses and clamps), ال “Charge Air Logic” (the boost hose), ال “Degassing Logic” (the air bleed network), و “منطق الختم” (the critical banjo clamps that ensure a leak-proof system).

جوهر 1: ال “Primary Circulation” Pipework (عناصر 3, 4, 5, 6)

This group represents the “main arteries” التابع أنابيب فاو J6P نظام, responsible for moving the bulk of the engine coolant. A failure here is catastrophic.

1. عنصر: ‘Radiator inlet hose’ (1303011-14ب)
هذا (شركات 4) هو “Hot Side Logic.” This high-temperature hose carries 90°C+ coolant *from* the engine’s thermostat housing *to* the ‘Radiator assy’ (شركات 1). It is engineered from reinforced EPDM rubber to withstand high heat, high pressure, and constant engine vibration.

2. عنصر: ‘Radiator outlet hose’ (1303021-14ب)
هذا (شركات 6) هو “Cold Side Logic.” It carries the now-cooled (على سبيل المثال, 80درجة مئوية) coolant *from* the bottom of the radiator *back to* the ‘Water Pump’ (الفصل 19) to re-enter the engine block. This hose is under “شفط” from the water pump, so its internal reinforcement must prevent it from “collapsing” inward.

3. عنصر: ‘Banjo-type hose clamp B model’ (CQ67670B, CQ67680B)
هؤلاء (شركات 3, 5) هي “Sealing Integrity Logic” and are the most critical “Smallest Serviceable Units” in the أنابيب فاو J6P نظام. These are not simple worm-gear clamps. أ “Banjo-type” (أو “T-Bolt”) clamp provides a 360-degree, عزم دوران عالي “Clamping Force Logic.” This ensures a perfect, leak-proof seal on the reinforced hoses, preventing coolant loss, which would lead to rapid engine overheating.

جوهر 2: ال “Charge Air” Pipework Logic (عناصر 28, 29)

هذا الجزء من أنابيب فاو J6P system handles “هواء,” not “coolant.” It manages the high-pressure “يعزز” from the turbocharger.

1. عنصر: ‘Intercooler connecting hose’ (1311034-50أ)
هذا (شركات 28) هو “Boost Logic” hose. The ‘Radiator assy’ (شركات 1) is a dual-core unit containing the “Charge Air Cooler” (المبرد). This hose’s “منطق” is to connect the “cold side” of the intercooler *to* the engine’s intake manifold.

هذا أنابيب فاو J6P component is engineered to handle 20-30+ PSI of boost pressure, oil mist (from the turbo), and high temperatures. It is likely made of multi-layer reinforced silicone to prevent it from “ballooning” or bursting under boost.

2. عنصر: ‘Banjo-type hose clamp B model’ (CQ67635B)
هذا (شركات 29) هو “Boost Sealing Logic.” أ “boost leak” is a common failure point that is catastrophic for performance. These high-torque clamps (الكمية 3) are essential to “lock” the ‘Intercooler connecting hose’ (شركات 28) onto the rigid pipes. أ “boost leak” from a failed clamp causes an immediate loss of power, excessive black smoke, and a “check engine” ضوء.

جوهر 3: ال “Degassing & Bypass” Pipework Logic

هذا هو “System Breathing Logic” network within the أنابيب فاو J6P. Its function is to remove trapped air, ال #1 enemy of a cooling system.

1. ال “Degassing Network” (عناصر 39, 40, 46, 17)
This includes the ‘Radiator rear degas pipe’ (1311069-76أ), ‘Radiator degas pipe’ (1311063-61ب), و ‘Engine degas pipe assy’ (1311025-138). هذا “Scavenging Logic” uses small-bore pipes to continuously “suck” air from the highest points of the system (the top of the radiator and the engine head).

هذا “Air-Free Logic” أمر بالغ الأهمية. Trapped air creates “steam pockets” that don’t transfer heat, تسبب “hot spots” that can warp a cylinder head. هذا أنابيب فاو J6P routes all scavenged air to the ‘Reservoir’ (1302052-01) (شركات 17), also known as the “خزان التوسع,” where the air is safely vented, and the coolant is returned to the system.

2. ال “Bypass Network” (عناصر 30, 31, 37, 41)
This group of أنابيب فاو J6P includes the ‘Return water pipe’ (1311062-14ب), ‘Connection steel pipe assy’ (1311035-61ب), ‘Front return water pipe’ (1311034-61ب), و ‘Connecting pipe assy’ (1311025-61ب). هذا هو “Bypass Logic” that allows hot coolant to flow to the “FAW J6P Cab Heater” (see Chapter 52), even when the engine’s main thermostat is closed.

جوهر 4: ال “المضادة للاهتزاز” منطق (The Context for the Pipework)

ال أنابيب فاو J6P (خراطيم) must be flexible for a specific reason: ال “محرك” و “المشعاع” do not move as one. This group explains the “Vibration Isolation Logic” that the pipework must compensate for.

1. ال “Isolated Mounting Logic” (عناصر 11, 12, 13)
The ‘Radiator assy’ (شركات 1) sits on a ‘Radiator bottom crossmember’ (1302030-61ب) and is held by “isolated” ‘Supports’ (1302027-70ش, 1302028-70ش). These mounts (see Chapter 38) use rubber to “damp” اهتزاز.

2. ال “Anti-Sway Logic” (عناصر 18, 19)
ال ‘Tie rod assy’ (1302050-01) و ‘Tie rod upper support’ (1302041-14ب) are diagonal stabilizers. They prevent the 30kg+ radiator from “swaying” و “shearing” when the truck’s chassis flexes.

هذا “Differential Movement Logic” is the final piece of the puzzle. ال أنابيب فاو J6P نظام, specifically the flexible hoses (شركات 4, 6, 28), هي “Flexible Coupling Logic” that “bridges the gap” between the vibrating engine and the “sway-damped” المشعاع. This prevents the “Anti-Vibration Logic” from “tearing” the rigid radiator ports off the engine.
