Purificador FAW: Um guia definitivo para o sistema de 4 partes para visão crítica em todos os climas

Welcome to this critical safety breakdown of the Purificador FAW, or windscreen washer, conjunto (P/N: 5207010-D03-C00). This system is a primary active-safety feature on the FAW Jiefang CA4251P66K24T1A3E5 6×4 trator semirreboque diesel. Isso é “lógica” is to work in perfect synchronization with the ‘FAW Windscreen Wiper’ (Conjunto 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, lama, and insect impacts.

O Purificador FAW is not just a bottle; é um “montagem lógica” that comprises several key sub-systems: a fluid reservoir, a high-pressure electric pump, fluid lines (mangueiras), and spray nozzles. O “lógica” is to store and deliver cleaning fluid on demand, pressurized and atomized, to the ‘Windscreen’ (Conjunto 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, gestores de frota, e especialistas em peças. Vamos desconstruir todo Purificador FAW assembly as detailed in the parts diagram. We will analyze the main ‘Washer assy’ (Universidade Estadual de Moscou 2) as the primary “black box” componente, and just as importantly, o crítico “installation logic” of the three other MSUs: the anti-vibration ‘lock nuts’ (Universidade Estadual de Moscou 3), and the ‘straps’ (Universidades Estadunidenses 1 & 4) that secure the system’s vital arteries.

Universidade Estadual de Moscou 2: The Core “Lógica” – Deconstructing the ‘Washer Assy’ (5207010-D03-C00)

Este componente é o “mais longo” and most complex part of the Purificador FAW sistema. The ‘Washer assy’ (5207010-D03-C00) is the primary MSU, a “black box” unit that is replaced as a single part. Isso é “lógica” is to combine three critical functions into one pre-sealed, factory-tested assembly.

1. The Reservoir “Lógica” (Armazenar)

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

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

• Chemical Resistance: It is completely inert to the methanol, ethylene glycol (anticongelante), 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.

Projeto: The reservoir is molded into a complex, vehicle-specific shape to maximize fluid capacity (often 3-5 litros) 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 “Lógica” (Poder)

Integrated into the base of the reservoir is the electric washer pump. Este é o “músculo” do Purificador FAW. It is a 24V DC motor that drives a small centrifugal impeller.

Isso é “lógica” is to provide high pressure (PSI) to atomize the fluid at the nozzles. It is mounted at the *bottom* of the tank, a “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, qual (via a relay) sends power to this motor.

3. The Fluid Level Sensor “Lógica” (Aviso)

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

This signal is sent to the ‘Combination Instrumentation’ (Conjunto 589), illuminating the amber “Low Washer Fluid” luz de advertência. This gives the driver advanced notice to refill, garantindo o Purificador FAW 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’ Universidade Estadual de Moscou.

O “Delivery Logic”: Mangueiras & Bicos (Implicit MSUs)

While the ‘Washer assy’ is the heart, o Purificador FAW system relies on two other (implicit) sets of components to function: hoses and nozzles.

Mangueira “Lógica”: The system uses flexible EPDM rubber or nylon tubing to connect the pump’s output port to the nozzles. O “lógica” of this tubing is durability. It must be routed safely through the engine bay, secured by the ‘Harness clips’ (Universidade Estadual de Moscou 1) and ‘Plastic straps’ (Universidade Estadual de Moscou 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 “Lógica”: The fluid is expelled through two or three “nozzles” (ou “jets”) located on the cowl panel or on the wiper arms themselves. O “lógica” of a modern nozzle is “atomization.” They are not simple “squirters.” They are engineered to break the fluid into a fine, wide “fã” spray that covers the maximum glass area, allowing the ‘Windscreen Wiper’ (629) to clear the glass in a single pass.

Essencial 3: O “Installation & Protegendo” Lógica (Universidades Estadunidenses 1, 3, 4)

The remaining 3 MSUs in the Purificador FAW parts list form the complete installation and routing kit. Deles “lógica” is to ensure the system is mounted securely and its “arteries” (hoses and wires) are protected.

Universidade Estadual de Moscou 3: ‘Hexagon head flange lock nut’ (Q032606) – Quantidade 3

Este é o “antivibração” mounting logic. The ‘Washer assy’ (Universidade Estadual de Moscou 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. Eles são “flange lock nuts.”

• Flange: Acts as an integrated washer to distribute the clamping force over the plastic mounting ear, preventing it from cracking.
• Lock: É um “Nyloc” (nylon insert) noz. 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. Esta é uma crítica, single-use MSU.

Universidades Estadunidenses 1 & 4: ‘Harness clip’ (3724012-A01) & ‘Plastic strap’ (T67414646) – Quantidade 7 total

Este é o “routing logic” para o Purificador FAW sistema. This kit of 7 clips and straps is used to secure the pump’s electrical wire and the fluid hose. Deles “lógica” 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.
