Блок логики FAW для трубопроводов кондиционирования и отопления: Декодирование 9 Основные компоненты комфорта

Welcome to this critical “comfort logic” analysis of the Блок логики FAW для трубопроводов кондиционирования и отопления (Сборка 716). Это полный, 9-тип компонента, “circulatory system” for the *heating* half of the HVAC system on the FAW Jiefang CA4251P66K24T1A3E5 6×4 трактор. Эта сборка является “логика” system that safely transports hot engine coolant (antifreeze) from the engine block to the in-cab ‘Heater Core’ (Сборка 709).

The “логика” принадлежащий Блок логики FAW для трубопроводов кондиционирования и отопления is to act as a durable, leak-proof, and heat-resistant “сантехника” network. It is designed to withstand 90-100°C temperatures, 15-20 PSI of pressure, and constant, high-frequency engine vibration. This system is the key to providing reliable cab heat for driver comfort and vital defrosting capabilities for the ‘Front Windscreen’ (Сборка 630).

This in-depth guide is essential for HVAC technicians and parts managers. Мы разберем всю Блок логики FAW для трубопроводов кондиционирования и отопления в свой 9 distinct serviceable component types. Мы проанализируем “multi-layer” logic of the main ‘Inlet/Outlet Hoses’, а “fume-seal” logic of the ‘Joints’, и критический “anti-chafe” logic of the 17-piece clamp, кронштейн, and fastener system.

Основной 1: The “Heat Transport” Логика (Компоненты 1 & 2) (The “дольше” Модуль)

The “arteries” принадлежащий Блок логики FAW для трубопроводов кондиционирования и отопления are its two main hoses. These are the primary serviceable components in this system.

1. Компонент 1: ‘Inlet hose’ (8116711-90ты)

Это “supply” линия. Его “логика” is to tap into the engine’s cooling system (НАПРИМЕР., at the cylinder head or water pump) and transport *hot* (90°C+) coolant *to* the ‘Heater Core’ (Сборка 709) inside the cab.

“Multi-Layer” Логика: This is not a simple rubber tube. Это “multi-layer” composite hose, typically made of an inner EPDM (Этилен-пропилен-диеновый мономер) резина, a central “rayon” или “aramid” fiber reinforcement braid, and a tough, abrasion-resistant outer EPDM cover. Этот “логика” is critical for:

• Pressure: The fiber braid allows the hose to withstand the 15-20 PSI of the cooling system without swelling or bursting.
• Химическая: The EPDM inner lining is chemically inert, preventing it from being degraded by the ethylene glycol (antifreeze) in the coolant.

2. Компонент 2: ‘Outlet hose’ (8116712-90ты)

Это “return” линия. After the coolant has “dumped” its heat into the ‘Heater Core’ (709), this hose’s “логика” is to transport the (now cooler) coolant *back* to the engine’s cooling system (НАПРИМЕР., to the radiator or water pump) to be re-heated.

3. The “Molded-Fit” Логика (Both Hoses):

The most critical “логика” of these hoses is their shape. They are not straight. Они есть “pre-molded” at the factory into a specific, 3D shape. Этот “логика” is essential for a safe, reliable installation. The pre-molded bends are designed to *perfectly* route the hose around the hot ‘Exhaust Manifold’ (Сборка 132), the moving steering column, and the vibrating engine block.

Удобство обслуживания: Hoses are the #1 failure point in a heating system. After 5-10 годы, the EPDM rubber hardens, becomes brittle, и “cold-leaks” at the ‘Clamps’ (Компонент 3), or develops “soft spots” and bulges, which can lead to a catastrophic burst. A burst heater hose will rapidly drain the engine of coolant, leading to overheating. This makes these hoses a critical, high-wear serviceable part.

Основной 2: The “Interface & Anchor” Логика (Компоненты 5, 7, 8)

This group of components is the “infrastructure” принадлежащий Блок логики FAW для трубопроводов кондиционирования и отопления.

Компоненты 5 & 7: ‘Water pipe joint’ (8116061-90ты & 8116703-590): Это “interface” логика. Это “firewall pass-throughs.”

Их “логика” is to provide a “bulkhead” связь, allowing the rubber ‘Inlet/Outlet Hoses’ to safely pass through the cab’s metal firewall (‘Welded Cab Assembly’ 617). They are made of corrosion-proof polymer or brass. Their most critical “логика” is the integrated “grommet,” which creates a 100% airtight seal. Этот “fume-seal” logic is a safety feature that prevents engine bay fumes (CO) from being “sucked” into the cab’s HVAC intake.

Компонент 8: ‘Heater water pipe fixed bracket’ (8116074-91Вт): Это “якорь” логика. A long, 1-meter hose, full of heavy water and vibrating with the engine, является “uncontrolled” компонент. This bracket’s “логика” is to be the “якорь,” securely fastening the hoses (via clamps) к шасси. Этот “anti-chafe” logic prevents the hoses from rubbing against the frame, which would eventually wear a hole.

Основной 3: The “Anti-Leak” & “Анти-раздражение” Логика (Компоненты 3, 4, 6, 9)

This final group of 11 components is the “fastening logic” для Блок логики FAW для трубопроводов кондиционирования и отопления.

Компоненты 3 & 6: ‘Worm-drive hose clamp’ (CQ67627B / CQ67635B) – Кол-во 4 общий: Это “high-pressure seal” логика. These are *not* simple spring clamps. А “worm-drive” (screw-type) clamp provides a 360-degree, высокий крутящий момент “clamping” сила. Этот “логика” is what seals the rubber ‘Hoses’ (1 & 2) onto the metal/plastic ‘Joints’ (5 & 7), ensuring a leak-proof fit under 15+ PSI of pressure.

Компонент 4: ‘Plastic retaining strap’ (T67427946) – Кол-во 6: Это “anti-chafe” логика. Эти 6 straps (zip-ties) are critical serviceable parts. Их “логика” is to bundle the “входное отверстие” и “выход” hoses together and/or secure them *away* from other components (like the steering shaft). A missing strap is a primary cause of a “rub-through” hose leak.

Компонент 9: «Комбинированный болт’ (CQ1460620) – Кол-во 1: Это “антивибрационный” логика. This single bolt is used to mount the ‘Fixed Bracket’ (Компонент 8) к шасси. The “Комбинация” (комбинация) logic is its *captive lock washer*, which prevents the bracket from vibrating loose.
