Protection de ventilateur FAW J6P: Déconstruction 46 Pièces critiques pour un contrôle parfait du flux d’air

This is an expert technical deconstruction of the Protection de ventilateur FAW J6P (also known as the ‘Fan shroud’, Comp 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 tombereau. This component is not a simple “garde”; it is an “Aerodynamic Logic” outil.

Le Protection de ventilateur FAW J6P creates a “vacuum tunnel,” forcing the engine fan (see Chapter 20) to pull 100% of its air *through* the ‘Radiator assy’ (Comp 1). Without this shroud, a fan is extremely inefficient, pulling air from the “path of least resistance” (the sides) et “stalling.” Ce “Airflow Funnel Logic” is the difference between peak cooling and catastrophic overheating.

This guide is essential for fleet technicians and parts specialists. Le Protection de ventilateur FAW J6P is made of a composite polymer, et son #1 enemy is vibration, which causes fatigue cracks. We will deconstruct the entire 46-part system, focusing on the “Airflow Logic” (the guard itself), le “Heat Exchange Context” (the radiator it serves), et le “Anti-Vibration Logic” (the complex web of brackets, tie-rods, and fasteners that protect it).

Cœur 1: Le “Airflow Funnel” Logique (Composant 2)

Ce composant est le “hero” of this assembly. All other 45 parts are in service to this component’s function.

1. Composant: ‘Fan shroud’ (1309010-14B)
Ce (Comp 2) *is* the Protection de ventilateur FAW J6P. C'est “Aerodynamic Logic” is more complex than it appears. It is not a simple “boîte” ou “guard.” It is an engineered “shroud” ou “tunnel” designed to optimize airflow.

Le “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” de la Protection de ventilateur FAW J6P. If this gap is too large, air “recirculates” from the high-pressure side back to the low-pressure side, “stabulation” the fan and destroying its efficiency.

Ce “Vacuum Logic” est tout son but. Le Protection de ventilateur FAW J6P creates a “sealed” environment, forcing the fan to pull a “vacuum” *across the entire surface area* of the ‘Radiator assy’ (Comp 1) fins. This ensures even cooling and prevents “hot spots.”

“Material Logic” is also key. This part is made from a “glass-reinforced polymer” (a composite). It must be lightweight, but also rigid enough to not “flex” ou “warp” from the 100°C+ heat radiating off the engine. It must also absorb constant, high-frequency vibration.

Le “Failure Mode Logic” est “fatigue cracking.” A heavy-duty truck chassis flexes constantly. This vibration is the #1 enemy of the Protection de ventilateur FAW J6P. A small crack, starting from a mounting bolt, volonté “araignée” across the shroud, breaking the “vacuum seal” and causing an immediate, drastic loss in cooling performance.

Cœur 2: Le “Heat Exchange” Contexte (Composant 1)

Le Protection de ventilateur FAW J6P is useless without the component it is designed to “serve”: the ‘Radiator assy’.

1. Composant: ‘Radiator assy’ (1301010-14B)
Ce (Comp 1) est le “Heat Exchange Logic.” C'est un grand, passif “heat sink” for both the engine coolant and the turbocharger’s “charge air” (via the intercooler). En tant que “passif” device, it relies 100% on *airflow* to dissipate heat.

Le “Symbiotic Logic” is that the Protection de ventilateur FAW J6P (Comp 2) is *mounted directly* to the frame of the ‘Radiator assy’ (Comp 1). Its design “scellés” it against the radiator’s edges. Ce “Matched Set Logic” ensures that any air pulled by the fan *must* first pass *through* the radiator’s fins.

The survival of the Protection de ventilateur FAW J6P is therefore directly “tied” to the survival of the radiator. The radiator provides the “mounting-face” et “structural support” for the fan shroud.

Cœur 3: Le “Anti-vibrations” Mounting Logic (The Guard’s Life Support)

This group represents the complex “Vibration Isolation Logic.” Since the Protection de ventilateur FAW J6P est (brittle) composite and the chassis/engine (vibrant) is steel, this system is what prevents the Protection de ventilateur FAW J6P depuis “tremblement” itself to pieces.

1. Le “Isolation Logic” (Composants 11, 12, 13)
The entire ‘Radiator assy’ (which holds the fan guard) sits on a ‘Radiator bottom crossmember assy’ (1302030-61B). Ce “shelf” is held by the ‘Radiator left support’ (1302027-70U) et ‘Radiator right support’ (1302028-70U). Ces “prend en charge” use large rubber “isolator” bagues (see Chapter 38) à “damp” the raw vibration from the frame.

2. Le “Anti-Sway Logic” (Composants 18, 19)
C'est le “Shearing Force Logic” protection. Le ‘Tie rod assy’ (1302050-01) et ‘Tie rod upper support’ (1302041-14B) are diagonal stabilizers. When the truck hits a pothole, the chassis “flexes.” These tie rods prevent the radiator and the attached Protection de ventilateur FAW J6P from being “twisted” ou “swayed,” which would cause an instant “fatigue crack.”

3. Le “Frame Logic” (Composants 8, 22, 26, 33, 35)
Ce “web” of steel (‘Radiator connecting plate’ (1301020-61B), ‘Radiator support plate’ (1302040-14B), etc.) est le “Structural Logic.” It creates a “rigid cage” around the “isolated” radiateur, providing the secure mounting points for the Protection de ventilateur FAW J6P.

Cœur 4: Le “System Integration” Logique (SSU & Plumbing)

This final group includes all “Smallest Serviceable Units” (SSU) et le “Plumbing” that must co-exist with the Protection de ventilateur FAW J6P.

1. Le “Logique de fixation” (Boulons, Noix, Rondelles)
This includes all “Hardware Logic,” tel que « Boulon à bride hexagonale’ (Q1840816, Q1841230, etc.), ‘Combination bolt’ (CQ1460820), et ‘Hexagon nuts’ (CQ34010, CQ34008, etc.). Ce sont les “Vibration-Proof Logic” attaches.

A single loose bolt (Par exemple, Comp 7, which holds the Protection de ventilateur FAW J6P‘s support plate) will create a “vibration hot spot” et “hammer” the composite shroud until it cracks. This is why high-tensile, “flanged” (self-locking) hardware is essential.

2. Le “Plumbing Logic” (Tuyaux & Pinces)
This group includes all the hoses (‘Radiator inlet hose’ (1303011-14B), ‘Radiator outlet hose’ (1303021-14B), etc.) and their high-torque ‘Banjo-type hose clamps’ (CQ67670B, etc.).

Le “Routing Logic” of this plumbing is designed *around* the Protection de ventilateur FAW J6P. The hoses must be “flexible” to absorb the vibration between the “moteur” et le “radiateur” assemblée. They are routed to clear the shroud and, more importantly, le “spinning” ventilateur (Chapitre 20) *inside* the shroud.
