جهاز غسيل فاو: دليل نهائي لنظام مكون من 4 أجزاء للرؤية الحرجة في جميع الأحوال الجوية

Welcome to this critical safety breakdown of the جهاز غسيل فاو, or windscreen washer, حَشد (ف / ن: 5207010-D03-C00). This system is a primary active-safety feature on the FAW Jiefang CA4251P66K24T1A3E5 6×4 جرار نصف مقطورة ديزل. إنه “منطق” is to work in perfect synchronization with the ‘FAW Windscreen Wiper’ (حَشد 629) to provide the driver with a clear, unobstructed field of vision. This is essential for safe operation in all weather, especially when dealing with road salt, الطين, and insect impacts.

ال جهاز غسيل فاو is not just a bottle; it is a “التجمع المنطقي” that comprises several key sub-systems: a fluid reservoir, a high-pressure electric pump, fluid lines (خراطيم), and spray nozzles. ال “منطق” is to store and deliver cleaning fluid on demand, pressurized and atomized, to the ‘Windscreen’ (حَشد 630). This system is designed for high-vibration, all-weather environments, from sub-zero winters to high-heat summer operation.

This in-depth guide is an essential resource for technicians, مديري الأسطول, ومتخصصين في قطع الغيار. سنقوم بتفكيك الكل جهاز غسيل فاو assembly as detailed in the parts diagram. We will analyze the main ‘Washer assy’ (جامعة ولاية ميشيغان 2) as the primary “الصندوق الأسود” عنصر, and just as importantly, the critical “منطق التثبيت” of the three other MSUs: the anti-vibration ‘lock nuts’ (جامعة ولاية ميشيغان 3), and the ‘straps’ (وحدات التخزين المتنقلة 1 & 4) that secure the system’s vital arteries.

جامعة ولاية ميشيغان 2: The Core “منطق” – Deconstructing the ‘Washer Assy’ (5207010-D03-C00)

This component is the “لفترة أطول” and most complex part of the جهاز غسيل فاو نظام. The ‘Washer assy’ (5207010-D03-C00) is the primary MSU, أ “الصندوق الأسود” unit that is replaced as a single part. إنه “منطق” is to combine three critical functions into one pre-sealed, factory-tested assembly.

1. The Reservoir “منطق” (تخزين)

The main body of the ‘Washer assy’ is the fluid reservoir (ال “bottle”). This is not a simple container. إنه “منطق” is based on material science and design.

مادة: It is blow-molded from High-Density Polyethylene (HDPE). This material is chosen for its specific “منطق”:

• Chemical Resistance: It is completely inert to the methanol, ethylene glycol (antifreeze), and detergents found in washer fluid.
• Temperature Resistance: It will not become brittle and crack in deep-freeze conditions, nor will it warp or soften from high engine-bay heat.
• Translucency: The plastic is semi-transparent, allowing a quick, visual check of the fluid level without opening the cap.

تصميم: The reservoir is molded into a complex, vehicle-specific shape to maximize fluid capacity (often 3-5 لتر) while fitting perfectly into the unused, irregular space in the engine bay. It includes a long, ergonomic filler neck and a “breather” cap.

2. The Electric Pump “منطق” (قوة)

Integrated into the base of the reservoir is the electric washer pump. هذا هو “عضلة” التابع جهاز غسيل فاو. It is a 24V DC motor that drives a small centrifugal impeller.

إنه “منطق” is to provide high pressure (رطل لكل بوصة مربعة) to atomize the fluid at the nozzles. It is mounted at the *bottom* of the tank, أ “gravity-fed” logic that ensures the pump is always primed and can use every last drop of fluid. The pump is activated by the ‘Combination Switch’ on the steering column, أيّ (via a relay) sends power to this motor.

3. The Fluid Level Sensor “منطق” (Warning)

Also integrated into the ‘Washer assy’ is a low-fluid-level sensor. This is a critical HMI “منطق” وظيفة. It is typically a “reed switch” with a “float.” When the fluid level drops, a magnetic float sinks, closing an electrical circuit.

This signal is sent to the ‘Combination Instrumentation’ (حَشد 589), illuminating the amber “Low Washer Fluid” warning light. This gives the driver advanced notice to refill, ضمان جهاز غسيل فاو is always ready.

Because all three of these components are integrated, any failure (a cracked tank, a dead pump, or a faulty sensor) requires the replacement of the single ‘Washer assy’ جامعة ولاية ميشيغان.

ال “Delivery Logic”: خراطيم & الفوهات (Implicit MSUs)

While the ‘Washer assy’ is the heart, ال جهاز غسيل فاو system relies on two other (implicit) sets of components to function: hoses and nozzles.

Hose “منطق”: The system uses flexible EPDM rubber or nylon tubing to connect the pump’s output port to the nozzles. ال “منطق” of this tubing is durability. It must be routed safely through the engine bay, secured by the ‘Harness clips’ (جامعة ولاية ميشيغان 1) and ‘Plastic straps’ (جامعة ولاية ميشيغان 4) to prevent it from kinking, chafing, or melting on a hot exhaust manifold. A hole in this hose is a common failure, resulting in a weak or non-existent spray.

Nozzle “منطق”: The fluid is expelled through two or three “nozzles” (أو “jets”) located on the cowl panel or on the wiper arms themselves. ال “منطق” of a modern nozzle is “atomization.” They are not simple “squirters.” They are engineered to break the fluid into a fine, wide “معجب” spray that covers the maximum glass area, allowing the ‘Windscreen Wiper’ (629) to clear the glass in a single pass.

جوهر 3: ال “تثبيت & تأمين” منطق (وحدات التخزين المتنقلة 1, 3, 4)

The remaining 3 MSUs in the جهاز غسيل فاو parts list form the complete installation and routing kit. هُم “منطق” is to ensure the system is mounted securely and its “arteries” (hoses and wires) are protected.

جامعة ولاية ميشيغان 3: ‘Hexagon head flange lock nut’ (Q032606) – الكمية 3

هذا هو “المضادة للاهتزاز” mounting logic. The ‘Washer assy’ (جامعة ولاية ميشيغان 2) has three molded-in mounting points that slide over fixed studs on the cab’s inner fender or firewall. These three nuts are what hold the entire 10-pound (when full) assembly in place.

They are not standard nuts. هم “flange lock nuts.”

• شفة: Acts as an integrated washer to distribute the clamping force over the plastic mounting ear, preventing it from cracking.
• Lock: إنه أ “نيلوك” (nylon insert) nut. This insert creates intense friction, making the nut *immune to vibration*. A standard nut would shake loose from engine harmonics, causing the reservoir to rattle and fail. هذا أمر بالغ الأهمية, single-use MSU.

وحدات التخزين المتنقلة 1 & 4: ‘Harness clip’ (3724012-أ01) & "حزام من البلاستيك."’ (ت67414646) – الكمية 7 total

هذا هو “routing logic” ل جهاز غسيل فاو نظام. This kit of 7 clips and straps is used to secure the pump’s electrical wire and the fluid hose. هُم “منطق” is to prevent chafing and heat damage. A technician uses these MSUs to fasten the hose/wire securely to the chassis, far away from the hot engine block, the exhaust manifold, and any moving parts (like the steering shaft or fan belts). A missing clip can lead to a melted hose or a shorted wire, disabling the entire system.
