انسداد أرضية FAW: ال 7 وحدات MSU الأساسية للهدوء, سيارة أجرة خالية من الصدأ

مرحبًا بك في هذا الدليل الأساسي حول انسداد أرضية FAW حَشد. This is the complete 30-piece kit of engineered seals, الحلقات, and plugs for the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار. These components are not cosmetic; they are a critical first-line defense for the cab’s integrity. Their core “منطق” is to create a hermetic, “triple-threat” seal for the cab’s floor pan, protecting the driver and the vehicle from noise, ماء, والأبخرة.

ال انسداد أرضية FAW system is a foundational component of the cab’s Noise, اهتزاز, والقسوة (NVH) طَرد. ال “منطق” of this kit is to permanently seal the various access and drainage holes left in the sheet metal during the manufacturing (stamping, e-coating) process. Leaving these holes open would allow a direct path for engine noise, road spray, and dangerous exhaust gases to enter the cab.

This in-depth guide is a vital resource for body shop technicians, متخصصون في الاصطدام, ومديري قطع الغيار. سنقوم بتفكيك الكل انسداد أرضية FAW kit into its 7 الحد الأدنى المتميز للوحدة القابلة للخدمة (جامعة ولاية ميشيغان) أنواع. We will analyze the material science, the multi-functional sealing “منطق,” and the specific location logic for each of the 30 قِطَع.

ال “الختم الثلاثي” منطق: ضوضاء, ماء & Fume Barrier

ال انسداد أرضية FAW assembly is not about aesthetics; it is about “منطق الختم” A single missing plug can compromise the entire cab environment. This 30-piece kit provides three critical barrier functions.

1. Acoustic Sealing (منطق NVH):

الابتدائي “منطق” is to block noise. The cab sits directly over the engine, الانتقال, and road. A single un-plugged hole acts as a “sound leak,” allowing low-frequency engine drone and high-frequency tire/wind hiss to enter the cab. This noise dramatically increases driver fatigue.

هؤلاء انسداد أرضية FAW plugs are made from dense, heavy EPDM rubber. They function as “acoustic dampers,” a key part of the ‘Soundproofing Pad’ نظام (حَشد 623). They have the mass to block and reflect sound waves, ensuring the cab remains quiet.

2. ماء & Corrosion Sealing Logic:

هذا هو “منطق” of longevity. The front tires constantly spray water, الطين, and corrosive road salt against the underside of the cab. إذا كان المكونات مفقودة, this moisture is injected *under* the cab’s floor covering.

This trapped moisture saturates the sound deadening pads, which acts like a sponge against the bare metal floor. هذا هو #1 cause of cab floor rust-out, which rots the cab from the inside. واحد مفقود انسداد أرضية FAW plug can destroy a floor pan.

3. الدخان & Air Sealing Logic:

هذا هو الابتدائي “safety logic.” The plugs on the firewall (‘Front Panel’) and transmission tunnel are a gas-tight seal. They prevent deadly, odorless Carbon Monoxide (CO) fumes from a potential exhaust leak from entering the driver’s breathing space.

This seal also stops drafts, تراب, and hot/cold air. هذا “منطق” is key to HVAC efficiency. By sealing these leaks, ال انسداد أرضية FAW kit ensures the A/C and heater can maintain temperature without running constantly, توفير الوقود.

مادة & منطق التصميم: مطاط إي بي دي إم

ال انسداد أرضية FAW plugs are not made from simple plastic. They are high-tech MSUs made from a specific material: إبدم (إيثيلين بروبيلين ديين مونومر) ممحاة.

المنطق المادي: EPDM is the “منطق” choice for this hostile environment.

• مقاومة درجات الحرارة: It will not get brittle and crack at -40°C, and it will not melt or get soft at +120°C from exhaust heat.
• Chemical Resistance: It is highly resistant to water, ملح الطريق, زيت, وقود الديزل, and brake fluid.
• Ozone/UV Resistance: The plugs on the firewall are exposed to engine bay ozone and UV light. EPDM will not crack or dry-rot like natural rubber.

منطق التصميم: These MSUs are designed for a one-way, “push-in” تثبيت. Each plug features a deep “أخدود” around its circumference. ال “منطق” is that the plug is pushed through the sheet metal hole until the metal “snaps” في هذا الأخدود. This creates a 360-degree, “interference fit” that is both waterproof and vibration-proof, ensuring the plug *cannot* be shaken loose.

تفكيك 7 أنواع جامعة ولاية ميشيغان (ال “أطول” الوحدة النمطية)

ال انسداد أرضية FAW kit contains 7 distinct part numbers (وحدات التخزين المتنقلة), المجموع 30 قِطَع. هذا “منطق” of having so many types is for precision. Each plug is precision-molded to fit a *specific* hole’s shape and diameter.

جامعة ولاية ميشيغان 7: Firewall Plugs (الكمية 2)

The ‘Round plug C-front panel’ (5302808-أ01) is designed for the “اللوحة الأمامية” (جدار الحماية). These two plugs seal holes in the vertical wall separating the driver from the engine.

وحدات التخزين المتنقلة 1-6: Floor Pan Plugs (الكمية 28)

هؤلاء 28 plugs are the main components of the انسداد أرضية FAW عدة, and they seal the horizontal floor of the cab. They are grouped by shape.

Round Plugs (وحدات التخزين المتنقلة 1, 4, 5):

• ‘Hole plug B’ (5109566-A95) – الكمية 2
• ‘Round plug D-floor’ (5109614-أ01) – الكمية 2
• ‘Round plug B-floor’ (5109617-أ01) – الكمية 2

ال “منطق” من هؤلاء 6 round plugs is to seal circular holes, likely from manufacturing alignment pins or small drainage holes. ال “ب,” “ج,” و “د” designations refer to specific, non-interchangeable diameters.

Oblong Plugs (وحدات التخزين المتنقلة 2, 3, 6):

• ‘Oblong plug B-floor’ (5109612-أ01) – الكمية 12
• ‘Oblong plug D-floor’ (5109613-أ01) – الكمية 9
• ‘Oblong plug C-floor’ (5109619-أ01) – الكمية 1

ال “منطق” من هؤلاء 22 oblong plugs is to seal the non-circular holes. The cab floor is stamped with ribs for strength. ال “الوديان” of these ribs are a common place for oblong drainage and access holes, and these MSUs are molded to fit them perfectly.

Each of these 7 part numbers is a distinct MSU. When servicing a cab (على سبيل المثال, replacing the ‘Floor Insulation Underlay’), it is critical to inspect for any missing or damaged plugs. Each missing plug must be replaced with the *exact* part number to ensure a perfect “interference fit” ختم.
