Module d'alimentation pour freins pneumatiques: Déconstruction 49 Pièces critiques pour une sécurité pneumatique sans faille

This is an in-depth technical guide to the Module d'alimentation pour freins pneumatiques Pour le FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. Cette déconstruction analyse 49 types de composants réparables, y compris les réservoirs d'air, air dryer, protection valves, and mounting hardware that form the core of the vehicle’s pneumatic system.

Le Module d'alimentation pour freins pneumatiques est le complet, integrated system responsible for generating, treating, stockage, and distributing the compressed air required for the entire braking system. On a heavy-duty dump truck, this is the most critical safety system. It is not just one part, but a network of components, including the ‘Air Dryer’ (to remove moisture), multiple ‘Air Tanks’ (for storage), and the ‘Four-Circuit Protection Valve’ (for redundancy). Tout cela Module d'alimentation pour freins pneumatiques must be free of leaks, mounted securely, and serviced regularly to ensure the vehicle has reliable stopping power under all load conditions. This analysis will deconstruct the core serviceable units of the Module d'alimentation pour freins pneumatiques, from generation to storage and distribution.

Cœur 1: Le “Generation & Treatment” Logique (The Air Dryer)

This group of components is the starting point of the Module d'alimentation pour freins pneumatiques. Il faut chaud, wet air from the engine’s compressor and “treats” il, making it clean and dry before sending it to the storage tanks.

1. Composant: ‘Air dryer assy’ (3511020-73UN) & ‘Air treatment unit’ (3515020-73UN)
Ces (Comp 21, 22) are the core of the treatment system. Le Air Treatment Logic is to remove moisture and oil from the compressed air. Wet, oily air will destroy the rubber seals in brake valves and can freeze in cold weather, leading to a catastrophic loss of brakes. This unit is a critical, serviceable part of the Module d'alimentation pour freins pneumatiques.

2. Composant: 'Support – air treatment unit’ (3515012-61B)
Ce (Comp 20) is the dedicated steel bracket that mounts the heavy air dryer assembly to the Cadre FAWJ6P. It is designed to withstand constant vibration.

3. Composant: 'Ensemble de tuyaux’ (3506235-73UN, 3506240-73UN) & ‘Silencer assy’ (3515025-55UN)
Ce (Comp 35, 36, 29) is the plumbing. The ‘Pipe assy’ (Comp 35, 36) are the multi-port manifolds that distribute the treated air. The ‘Silencer’ (Comp 29) is connected to the air dryer’s purge valve, muffling the loud “pssst” sound when the dryer purges its collected moisture. This is a key part of a properly functioning Module d'alimentation pour freins pneumatiques.

Cœur 2: Le “Stockage” Logique (The Air Tanks)

This group represents the various air reservoirs, ou “tanks,” that store the compressed air. Le Module d'alimentation pour freins pneumatiques uses multiple tanks for safety and redundancy.

1. Composant: ‘Reserve air tank assy’ (3513020-70B) & ‘Air tank assy’ (3513015-61B)
Ce (Comp 5, 7) is the main set of air tanks. These steel reservoirs hold the “primary” et “secondary” air for the service brake circuits, as divided by the protection valve.

2. Composant: ‘Dual-chamber air tank assy’ (3513215-54UN) & ‘Partition air tank’ (3513411-50UN)
Ce (Comp 30, 16) represents specialized tanks. Le Redundancy Logic is that a ‘Dual-chamber’ tank (Comp 30) is a single tank with two isolated compartments inside. This is often used for the park brake, ensuring it has its own dedicated air supply that cannot be depleted by a service brake leak. This is a core feature of the Module d'alimentation pour freins pneumatiques.

3. Composant: ‘Drain valve assy’ (3513100-240) – Quantité 6 (Total)
Ce (Comp 8, 9) is the most critical service item. Chaque Réservoir d'air de réserve FAW J6P (which is part of the Module d'alimentation pour freins pneumatiques) has a drain valve at the bottom. These must be opened daily to purge the condensed water, which is a byproduct of air compression. Failure to drain the tanks will lead to brake failure in cold weather.

Cœur 3: Le “Distribution & Protection” Logique (Vannes & Montures)

This group includes the “cerveau” de la Module d'alimentation pour freins pneumatiques and the hardware that physically secures the tanks to the truck frame.

1. Composant: ‘Four-circuit protection valve’ (3515014-8E) – Quantité 3 (Total)
Ce (Comp 12, 27) is the central safety device. It receives the main air supply and splits it into four protected circuits (frein avant, rear brake, park brake, accessory). Le Logique de protection ensures that a leak in one circuit (Par exemple, a burst accessory line) cannot drain the entire system. This allows the brakes to remain functional, a critical feature of the Module d'alimentation pour freins pneumatiques.

2. Composant: Tank Brackets & Sangles (3513075-75UN, 3513095-75UN, 3513090-50UN, etc.)
Ce (Comp 6, 7, 17, 18, 32) is the complete mounting system. Le Logique des vibrations is that air tanks are heavy and subject to constant vibration. This system of heavy-duty ‘Brackets’ (Comp 6, 31) and steel ‘Strap assy’ (Comp 7, 18, 32) holds the tanks securely to the Cadre FAWJ6P, preventing metal fatigue and stress cracks.

3. Composant: ‘Air tank & battery box bracket assy’ (3513800-Y494)
Ce (Comp 5) is a large, integrated component that serves a dual purpose: it holds both an air tank for the Module d'alimentation pour freins pneumatiques and the vehicle’s batteries. This multi-function bracket, complete with ‘Battery box pad’ (Comp 34), is an example of efficient chassis design.
