Трубопровод FAW J6P: Деконструкция 46 Критические детали для герметичного термоконтроля

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

The Трубопровод FAW J6P system must simultaneously manage three “Fluid Logic” схемы. The “Primary Coolant Logic” (the main radiator hoses) moves high-temperature engine coolant. The “Charge Air Logic” (the intercooler hose) transports high-pressure, hot air from the turbo. The “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, менеджеры по техническому обслуживанию автопарка, и специалисты по запчастям. We will deconstruct every component of the Трубопровод FAW J6P сборка. Мы проанализируем “Primary Circulation Logic” (the main coolant hoses and clamps), а “Charge Air Logic” (the boost hose), а “Degassing Logic” (the air bleed network), и “Логика уплотнения” (the critical banjo clamps that ensure a leak-proof system).

Основной 1: The “Primary Circulation” Pipework (Компоненты 3, 4, 5, 6)

Эта группа представляет “main arteries” принадлежащий Трубопровод FAW J6P система, responsible for moving the bulk of the engine coolant. A failure here is catastrophic.

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

2. Компонент: ‘Radiator outlet hose’ (1303021-14Б)
Этот (Комп 6) это “Cold Side Logic.” It carries the now-cooled (НАПРИМЕР., 80° C.) coolant *from* the bottom of the radiator *back to* the ‘Water Pump’ (Глава 19) to re-enter the engine block. This hose is under “всасывание” from the water pump, so its internal reinforcement must prevent it from “collapsing” inward.

3. Компонент: ‘Banjo-type hose clamp B model’ (CQ67670B, CQ67680B)
Эти (Комп 3, 5) являются “Sealing Integrity Logic” and are the most critical “Smallest Serviceable Units” in the Трубопровод FAW J6P система. These are not simple worm-gear clamps. А “Banjo-type” (или “T-Bolt”) clamp provides a 360-degree, высокий крутящий момент “Clamping Force Logic.” This ensures a perfect, leak-proof seal on the reinforced hoses, preventing coolant loss, which would lead to rapid engine overheating.

Основной 2: The “Charge Air” Pipework Logic (Компоненты 28, 29)

This part of the Трубопровод FAW J6P system handles “воздух,” not “coolant.” It manages the high-pressure “способствовать росту” from the turbocharger.

1. Компонент: ‘Intercooler connecting hose’ (1311034-50А)
Этот (Комп 28) это “Boost Logic” hose. The ‘Radiator assy’ (Комп 1) is a dual-core unit containing the “Charge Air Cooler” (Промежуточный охладитель). This hose’s “логика” is to connect the “cold side” of the intercooler *to* the engine’s intake manifold.

Этот Трубопровод FAW 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. Компонент: ‘Banjo-type hose clamp B model’ (CQ67635B)
Этот (Комп 29) это “Boost Sealing Logic.” А “boost leak” is a common failure point that is catastrophic for performance. These high-torque clamps (Кол-во 3) are essential to “замок” the ‘Intercooler connecting hose’ (Комп 28) onto the rigid pipes. А “boost leak” from a failed clamp causes an immediate loss of power, excessive black smoke, и “check engine” light.

Основной 3: The “Degassing & Bypass” Pipework Logic

Это “System Breathing Logic” network within the Трубопровод FAW J6P. Its function is to remove trapped air, а #1 enemy of a cooling system.

1. The “Degassing Network” (Компоненты 39, 40, 46, 17)
This includes the ‘Radiator rear degas pipe’ (1311069-76А), ‘Radiator degas pipe’ (1311063-61Б), и ‘Engine degas pipe assy’ (1311025-138). Этот “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).

Этот “Air-Free Logic” имеет решающее значение. Trapped air creates “steam pockets” that don’t transfer heat, causing “hot spots” that can warp a cylinder head. Этот Трубопровод FAW J6P routes all scavenged air to the ‘Reservoir’ (1302052-01) (Комп 17), также известный как “Расширение танка,” where the air is safely vented, and the coolant is returned to the system.

2. The “Bypass Network” (Компоненты 30, 31, 37, 41)
This group of Трубопровод FAW J6P includes the ‘Return water pipe’ (1311062-14Б), ‘Connection steel pipe assy’ (1311035-61Б), ‘Front return water pipe’ (1311034-61Б), и ‘Connecting pipe assy’ (1311025-61Б). Это “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.

Основной 4: The “Антивибрационный” Логика (The Context for the Pipework)

The Трубопровод FAW J6P (шланги) must be flexible for a specific reason: а “двигатель” и “радиатор” do not move as one. This group explains the “Vibration Isolation Logic” that the pipework must compensate for.

1. The “Isolated Mounting Logic” (Компоненты 11, 12, 13)
The ‘Radiator assy’ (Комп 1) sits on a ‘Radiator bottom crossmember’ (1302030-61Б) and is held by “изолированный” ‘Supports’ (1302027-70ты, 1302028-70ты). These mounts (see Chapter 38) use rubber to “damp” вибрация.

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

Этот “Differential Movement Logic” is the final piece of the puzzle. The Трубопровод FAW J6P система, specifically the flexible hoses (Комп 4, 6, 28), являются “Flexible Coupling Logic” that “bridges the gap” between the vibrating engine and the “sway-damped” радиатор. This prevents the “Anti-Vibration Logic” from “tearing” the rigid radiator ports off the engine.
