مجموعة خزان الهواء المساعد FAW: تحليل نقدي ل 10 المكونات الأساسية

مرحبًا بكم في هذا التحليل الفني النقدي لـ مجموعة خزان الهواء المساعد FAW (حَشد 543). هذا كامل, chassis-mounted, high-pressure air reservoir system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. This assembly serves as a vital “auxiliary” storage unit for the truck’s complex pneumatic brake and suspension systems.

ال مجموعة خزان الهواء المساعد FAW هو “منطق” system designed to provide redundant or specialized air capacity. While the main air brake module (حَشد 542) provides primary storage, this ‘Dual-chamber air storage tank assembly’ (3513075-91دبليو) offers dedicated air volume for systems like the trailer brakes, parking brakes, or the pneumatic-over-hydraulic clutch, ensuring system integrity.

يعد هذا الدليل المتعمق موردًا أساسيًا لفنيي الهياكل المحترفين والمتخصصين في قطع الغيار. سنقوم بتفكيك الكل مجموعة خزان الهواء المساعد FAW فيه 10 أنواع المكونات الصالحة للخدمة, including the dual-chamber tank, the ‘Drain valve assembly’, the ‘Tank strap assembly’, the chassis-mounted ‘Bracket assembly’, and all the critical high-pressure fittings and fasteners.

المكون الأساسي: ‘Dual-Chamber Air Storage Tank’ (3513075-91دبليو)

قلب ال مجموعة خزان الهواء المساعد FAW is the ‘Dual-chamber air storage tank assembly’ (3513075-91دبليو). هذا هو واجب ثقيل, steel-walled cylinder, but its “dual-chamber” nature is its key “منطق.” This is not just one open tank; it has an internal, welded baffle that divides it into two separate, airtight reservoirs.

هذا “dual-chamber” logic is a critical safety feature of the مجموعة خزان الهواء المساعد FAW. It allows this single component to serve two different, isolated brake circuits. على سبيل المثال, one chamber might be dedicated to the trailer’s service brakes, while the other chamber is dedicated to the truck’s spring (parking) brakes.

This ensures that a catastrophic failure in one circuit (like a severed trailer air line) cannot drain the air from the *other* circuit. This redundancy is the core “منطق” of a safe, modern air brake system. ال مجموعة خزان الهواء المساعد FAW is a key part of this redundant design. These tanks are designed to hold air at 120-130 PSI and must be free from external damage or internal rust, which could lead to a catastrophic rupture.

نظام التركيب: قوس (3513075-75أ) & الأشرطة (3513085-91دبليو)

A heavy, air-filled tank must be securely mounted to the chassis. ال مجموعة خزان الهواء المساعد FAW uses a robust, two-part system.

**1. ‘Bracket assembly-auxiliary air tank’ (3513075-75أ):** هذا هو الشيء الرئيسي “الرف” أو “cradle.” إنها مهمة ثقيلة, fabricated steel bracket that bolts directly to the truck’s main C-channel frame rail. This bracket provides the rigid, structural support for the tank. هذا المكون من مجموعة خزان الهواء المساعد FAW is secured to the chassis using ‘Hex flange bolts’ (Q1841440, Q1841475) و"صواميل قفل شفة سداسية الرأس".’ (CQ32614), ensuring a vibration-proof connection.

**2. ‘Tank strap assembly-auxiliary air tank’ (3513085-91دبليو):** قائمة الأجزاء تدعو إلى اثنين من هذه. These are high-tensile steel bands that “حزام” the cylindrical tank down into its cradle bracket. These straps are what prevent the tank from shifting or falling off. They are designed to be tensioned with bolts to provide a high-clamping force. This bracket-and-strap “منطق” is the standard for safely mounting cylindrical air tanks, and it is a key part of the مجموعة خزان الهواء المساعد FAW.

خدمة “منطق”: Drain Valve (3513100-1500) and Test Port (T833)

ال “منطق” التابع مجموعة خزان الهواء المساعد FAW is designed around regular maintenance. The ‘Drain valve assembly’ (3513100-1500) is the most important serviceable component. القائمة تدعو لاثنين (one for each chamber of the dual-chamber tank).

Air from the engine’s compressor is hot and contains moisture. As this air cools in the tank, the moisture condenses into liquid water. This water is corrosive and dangerous; it can rust the steel tank from the inside out, and in cold weather, it can freeze, blocking the air lines and causing complete brake failure.

ال “منطق” of these drain valves is to provide a simple, manual way (usually a pull-cable or a petcock) for the driver to “بالُوعَة” this accumulated water from the tanks at the end of every day. This daily purge is the single most important PM task for the مجموعة خزان الهواء المساعد FAW.

"موصل اختبار الاتصال السريع."’ (T833) هو التشخيص “منطق” ميناء. It is a one-way, spring-loaded valve that allows a technician to quickly connect a pressure gauge to the مجموعة خزان الهواء المساعد FAW to test the system pressure, without having to disconnect a main (and dangerous) high-pressure line.

Fittings and Plumbing: The Grommet System

ال مجموعة خزان الهواء المساعد FAW must connect to the rest of the truck’s air system. This is done with a series of high-pressure, “اضغط للاتصال” style fittings. هذه هي “الحلقات” and their associated seals.

This parts list includes:

• **M22 Fittings:** Four ‘Grommet (م22) مع حلقة الختم عاصي’ (3513410-1500). These are the large ports, likely for the main supply *in* and the main service brake supply *out*.
• **M16 Fittings:** One ‘Grommet (M16) مع حلقة الختم عاصي’ (3506410-1500). This is a smaller port, perhaps for a sensor or the parking brake line.
• **سدادة:** One ‘Plug chamber (M16) مع حلقة الختم عاصي’ (3506415-1500), used to seal an unused M16 port.

ال “منطق” of these fittings is that they are sealed by ‘Special-shaped sealing rings’ (3513403-1500 for M22, 3506403-1500 for M16) and physically locked in place by ‘Circlips’ (3513407-1500 for Φ12, 3506407-1500 for Φ10). A failure of one of these small o-rings or circlips will cause a persistent, hard-to-find air leak, which is a major fault in any مجموعة خزان الهواء المساعد FAW.
