Réservoir d'air de réserve FAW J6P: Déconstruction 12 Pièces critiques pour des performances fiables des freins pneumatiques

This is an in-depth technical guide to the Réservoir d'air de réserve FAW J6P system for the FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau. Cette déconstruction analyse 12 primary serviceable components that form the critical air storage and distribution network, ensuring constant air pressure for the vehicle’s braking system.

Le Réservoir d'air de réserve FAW J6P is an essential component of the vehicle’s air brake system. These tanks store compressed air, which is vital for the proper operation of the service brakes, parking brakes, and various auxiliary air systems. Without a reliable supply of compressed air, the heavy-duty dump truck would be unable to stop safely. The system is designed with multiple tanks to ensure redundancy and dedicated air supplies for different circuits, enhancing overall safety. This deconstruction will analyze the key serviceable assemblies of the Réservoir d'air de réserve FAW J6P, including the main tank body, supports de montage, drain valves, and various sealing components. Maintaining a leak-free and properly functioning Réservoir d'air de réserve FAW J6P system is paramount for operational safety and regulatory compliance.

Cœur 1: Le “Storage” Logique (The Air Tank Body)

This group represents the core component of the Réservoir d'air de réserve FAW J6P système: the tank itself. It is designed to safely store compressed air under high pressure.

1. Composant: ‘Reserve air tank assy’ (3513020-70B) – Quantité 1
Ce (Comp 5) is the complete main air reservoir. These tanks are typically made of steel and are pressure-rated to safely hold compressed air for the braking system. Le Storage Logic ensures a constant supply of air pressure is available, even if the engine-driven compressor is not actively running. For the Réservoir d'air de réserve FAW J6P, multiple tanks are usually present, separating air supply for service brakes, parking brakes, and accessories.

2. Composant: ‘Plugs (M22)’ (3513421-50UN) – Quantité 2
Ces (Comp 9) are threaded plugs used to seal unused ports on the Réservoir d'air de réserve FAW J6P. These ports may be for auxiliary connections or maintenance access. Each plug must be properly torqued and sealed to prevent air leaks, which would compromise the efficiency and safety of the air brake system.

Cœur 2: Le “Montage & Sécurisation” Logique (Supports & Clamps)

This group ensures the Réservoir d'air de réserve FAW J6P is securely fastened to the vehicle’s frame, resisting vibrations and impacts during operation.

1. Composant: ‘Bracket assy – reserve air tank’ (3513075-75UN) – Quantité 2
Ces (Comp 6) are the heavy-duty brackets used to mount the Réservoir d'air de réserve FAW J6P securely to the chassis. They are typically made of strong steel to withstand the weight of the tank and the stresses of vehicle movement. Le Mounting Logic ensures that the tank does not move or detach, which would be extremely dangerous.

2. Composant: ‘Strap assy – reserve air tank’ (3513095-75UN) – Quantité 2
Ces (Comp 7) are metal straps that further secure the Réservoir d'air de réserve FAW J6P within its mounting brackets. They are designed to provide a tight fit, preventing any rattling or vibration that could lead to fatigue cracks in the tank or its connections over time. This dual approach of brackets and straps ensures maximum security.

3. Composant: « Boulon à bride à tête hexagonale’ (Q1841455, Q1841485) & ‘Hex head flange lock nut’ (CQ32614)
Ce (Comp 6 sub-parts) is the high-strength hardware used to fasten the brackets to the vehicle frame and secure the straps. These are typically self-locking nuts or have special washers to prevent them from loosening due to vibration, which is crucial for maintaining the integrity of the Réservoir d'air de réserve FAW J6P mounting.

Cœur 3: Le “Entretien & Scellage” Logique (Vannes & Joints)

This group includes the components necessary for maintaining the air tanks and ensuring a leak-proof system, which is paramount for the effectiveness of the Réservoir d'air de réserve FAW J6P.

1. Composant: ‘Drain valve assy’ (3513100-240) – Quantité 2
Ces (Comp 8) are critical maintenance items. Le Moisture Removal Logic is vital: compressed air contains water vapor, which condenses into liquid water inside the tanks. If not drained regularly, this water can freeze in cold weather, block air lines, and corrode the inside of the Réservoir d'air de réserve FAW J6P, leading to catastrophic failure. Regular draining of these valves is essential.

2. Composant: ‘Nuts (M22)’ (3513406-50UN) & ‘Clamps (Φ12)’ (3513407-50UN)
Ces (Comp 1 & 3) are various fastening components. The nuts are used for threaded connections, likely for air line fittings, while the clamps secure hoses. Precision is key; overtightening can damage components, while undertightening leads to leaks in the Réservoir d'air de réserve FAW J6P.

3. Composant: ‘Gaskets’ (3513408-50UN, 3513403-50UN, 3513028-73UN, CQ72316)
Ce (Comp 2, 4, 10, 12) is a range of sealing components. These include ‘Gasket (Φ18.5)’, ‘Shaped seal gasket (Φ15.6)’, and other ‘Sealing gaskets’. Each gasket is precisely sized and shaped to create an airtight seal between mating components, preventing any air loss from the Réservoir d'air de réserve FAW J6P. Their integrity directly impacts brake system performance.

4. Composant: ‘Four-circuit protection valve’ (3515014-8E) – Quantité 2
Ces (Comp 12) are crucial safety devices that often connect directly to the air tanks. Leur Redundancy Logic is that they isolate individual air circuits (Par exemple, front brakes, rear brakes, accessories) from each other. If a leak or failure occurs in one circuit connected to the Réservoir d'air de réserve FAW J6P, the valve will prevent pressure loss in the other, still-functional circuits, ensuring the truck can still brake safely.
