Compresseur d'air FAW J6P: Déconstruction 7 Pièces critiques pour une puissance aérienne parfaite

Bienvenue dans cette déconstruction experte du Compresseur d'air FAW J6P (Assemblage principal P/N 3509010-382). C'est le “compressed air generator” for the engine on the FAW Jiefang CA3250P66K2L1T1E 6×4 tombereau.

Ce n'est pas un accessoire optionnel; it is a safety-critical “Assemblage logique” de 7 types de composants. C'est “logique” is to convert engine rotational power into high-pressure (120-150 psi) compressed air, which is the lifeblood of the truck’s most critical systems: les freins à air, the clutch assist, the air suspension, and the horn.

Le “Logique de durabilité” is the most important feature of this Compresseur d'air FAW J6P. Unlike a belt-driven compressor, this unit is “gear-driven” (see Comp 1, ‘Driven gear’). Ce “Gear-Drive Logic” means it is directly integrated with the engine’s internal timing train. C'est un “durée de vie du moteur” solution, as there is no belt to slip, casser, or wear out—a critical design choice for a vehicle where a loss of air pressure means a total loss of braking. Ce Compresseur d'air FAW J6P is a piston-style pump, which requires its own lubrication and cooling.

This technical guide is an essential resource for engine technicians, spécialistes du châssis, et gestionnaires de pièces. We will deconstruct the entire 7-component-type group. Nous analyserons le “Air Generation Logic” (the compressor assembly itself), le “Gear-Drive Logic” (the drive gear), le “Critical Lubrication Logic” (the oil inlet pipe and seals), et le “Scellage & Logique de fixation” (the hollow bolts and gaskets) that define this Compresseur d'air FAW J6P.

Cœur 1: Le “Air Generation” Logique (Composant 3)

This component is the main assembly, le “pompe” lui-même. Its logic is to convert the engine’s rotational power into high-pressure compressed air.

1. Composant: ‘Air compressor w/ pipe joint assy’ (3509010-382)
Ce (Comp 3) est le noyau Compresseur d'air FAW J6P assemblée. C'est un “piston pump” conception, essentially a miniature, single-cylinder (or twin-cylinder) engine that works in reverse. It is driven by the ‘Driven gear’ (Comp 1), which turns an internal crankshaft and drives a piston up and down.

Le “Valve Logic” est interne. On the “down-stroke,” the piston creates a vacuum, pulling in fresh, filtered air from the engine’s air intake via an “inlet reed valve.” On the “up-stroke,” it compresses this air to 120-150 psi. This high-pressure air forces open an “outlet reed valve” and is pushed into the ‘pipe joint assy’ (the outlet), heading to the truck’s air tanks.

Le “Logique thermique” est critique. Compressing air creates an immense amount of heat. Ce Compresseur d'air FAW J6P est “liquid-cooled.” It features an internal “veste d'eau” (passages de liquide de refroidissement) in its own cylinder head. Engine coolant is routed *through* the compressor body, where it absorbs this heat and carries it back to the main radiator. This is the only way the compressor can run continuously (un “100% duty cycle”) without seizing. Le “pipe joint assy” specifies that this is the version of the Compresseur d'air FAW J6P that includes the critical outlet fittings.

Cœur 2: Le “Engine-Drive” Logique (Composant 1)

Ce composant “logique” is to provide a reliable, “no-slip” power source for the Compresseur d'air FAW J6P.

1. Composant: ‘Driven gear – compresseur d'air’ (1006047-29D)
Ce (Comp 1) est le “Power Input Logic.” C'est un véhicule robuste, hardened steel gear. C'est “logique” is to mesh *directly* with a gear on the engine’s “Train à engrenages de distribution” (often the camshaft gear or an idler gear). Ce “Gear-Drive” design is the “Reliability Logic” for this safety-critical system. It *cannot* be driven by a belt, because a slipping or broken belt would mean an instant loss of brakes. This gear-on-gear connection ensures the Compresseur d'air FAW J6P is *always* spinning when the engine is running.

Le “Helical Logic” of the gear teeth is also important. The teeth are “hélicoïdal” (cut at an angle), not “éperon” (straight). This design “logique” allows the teeth to engage gradually and quietly. This reduces the “gémissement” (Nvh) of the gear train and, plus important encore, reduces the “shock load” on the teeth as they mesh. This is essential for the long-term durability of the Compresseur d'air FAW J6P‘s drive system.

Cœur 3: Le “Lubrification critique” Logique (Composant 7)

Ce groupe représente le “life-support” system for the Compresseur d'air FAW J6P. A piston pump cannot run dry.

1. Composant: ‘Engine oil inlet pipe assy – compresseur d'air’ (3509050-29D)
Ce (Comp 7) est le “Pressure Feed Logic.” C'est “logique” is to be a high-pressure, rigid steel pipe that “robinets” faire le ménage, pressurized oil directly from the engine’s main “oil gallery” (likely on the side of the engine block). This pipe’s “logique” is to provide a constant, pressurized stream of oil *into* the Compresseur d'air FAW J6P‘s internal crankcase.

This oil performs two critical functions:

• Lubrification: It lubricates the compressor’s own internal crankshaft, roulements, and piston cylinder wall.
• Refroidissement: Il fournit “splash cooling” to the underside of the compressor’s piston, drawing heat away and transferring it back to the engine’s main oil supply.

Un échec dans ce domaine “Lubrication Logic”—a clogged pipe, a loose “hollow bolt” (Comp 5), or a failed “copper gasket” (Comp 6)—will starve the Compresseur d'air FAW J6P of oil. This will cause it to overheat and seize in a matter of minutes, disabling the truck’s entire air system.

Cœur 4: Le “Scellage & Attache” Logique (Tous les autres)

Ce dernier groupe “logique” est de fournir une sécurité, résistant aux vibrations, and *leak-proof* mounting for the Compresseur d'air FAW J6P and its fluid lines.

1. Le “Structural Fastener” Logique (Composant 4)
The ‘Hexagon flange bolt’ (Q1841035), of which there are three (3), est le “Mounting Logic.” These are the high-tensile bolts that hold the entire Compresseur d'air FAW J6P assemblée (Comp 3) to its ‘support’ on the engine block. Le “Logique de bride” (built-in washer) is critical for resisting the “rocking” vibration of the piston pump, ensuring the bolts do not “marcher” lâche.

2. Le “Fluid Transfer” Logique (Composants 5, 6)
C'est le “Plumbing Hardware Logic” for the ‘Oil inlet pipe’ (Comp 7).

• ‘Hollow bolt’ (3509053-29D): La liste en appelle à deux (2) de ceux-ci “banjo bolts.” Leur “logique” is to allow fluid (huile) to flow *through* them, connecting the oil pipe to the engine block and to the Compresseur d'air FAW J6P entrée.
• ‘Copper gasket 10×16’ (Q/WC3403-1994): La liste en appelle à quatre (4) de ceux-ci. Ce “Crush Washer Logic” est critique. Deux (2) gaskets are used *per* hollow bolt (one on each side of the banjo fitting). The soft copper “écrase” une fois serré, creating a perfect, à haute pression, high-heat seal for the engine oil.

3. Le “Joint principal” Logique (Composant 2)
The ‘O-ring’ (Q734B1400265) est le “Mounting Gasket Logic.” Ce (Comp 2) is the large, high-temperature O-ring that seals the entire mounting flange of the Compresseur d'air FAW J6P au bloc moteur. C'est “logique” is to seal two things: 1) It seals the “pignon d'entraînement” (Comp 1) inside the timing case, preventing a massive oil leak. 2) It seals the “oil drain” chemin, allowing hot oil from the compressor’s crankcase to drain *back* into the engine’s main crankcase. A failure of this one O-ring will result in a major oil leak.
