معدات تكييف الهواء فاو J6P: تفصيل 18 الأجزاء المهمة لتحقيق المناخ الأمثل للمقصورة

Welcome to this comprehensive deconstruction of the معدات تكييف الهواء فاو J6P لفاو جيفانغ CA3250P66K2L1T1E 6×4 تفريغ الشاحنة. This is not a single part, but a complex, multi-component system. هذا الدليل تفاصيل 18 critical parts that ensure optimal driver comfort and safety.

ال معدات تكييف الهواء فاو J6P is a fully automatic climate control system, not a simple A/C. It is designed to heat, cool, منقي, and dehumidify the air within the J6P cab, maintaining a set temperature regardless of the harsh exterior conditions of a quarry or construction site.

This teardown will analyze the entire system, from the main ‘Two-Box’ HVAC unit (the heater and evaporator) to the electronic control head, the air filtration system, the ducting, and the critical drain hoses. لفني, a complete understanding of this system is essential for diagnosing refrigerant leaks, electrical faults, or poor performance.

A properly functioning معدات تكييف الهواء فاو J6P is a key factor in reducing driver fatigue and ensuring regulatory compliance. We will examine the logic of each part, from the main assemblies down to the specific hardware that holds them in place, ensuring a rattle-free and effective service.

جوهر 1: ال “Climate Core” منطق (The HVAC Unit)

This is the heart of the معدات تكييف الهواء فاو J6P, the main assembly hidden behind the dashboard that actually heats, cools, and moves the air.

1. عنصر: ‘Two-Box Assy – Automatic A/C’ (8100015-B27-C00) – الكمية 1
هذا (علامة 1) is the main HVAC (التدفئة, تهوية, وتكييف الهواء) وحدة. The term “Two-Box” refers to the two main heat exchangers contained within its single, large polymer housing: the heater core and the evaporator core.

The Heater Core Logic: This is a small radiator inside the “Two-Box” حَشد. Hot engine coolant is piped to it, and the blower fan forces cab air through its fins to provide heat.

The Evaporator Core Logic: هذا هو “cold” المشعاع. High-pressure liquid refrigerant (R134A) flows into it and expands into a gas, causing it to become ice-cold. Air blown through it is rapidly cooled and dehumidified. هذا هو “conditioning” part of the s معدات تكييف الهواء فاو J6P.

ال “Automatic” منطق: This assembly also contains multiple electric servo motors that control “blend doors.” These doors automatically mix air from the hot and cold cores to achieve the precise temperature set on the control panel (جوهر 2), without the driver having to manually adjust from hot to cold.

The Blower Logic: The main electric blower motor (معجب) is also integrated into this housing, providing the high-volume airflow required to heat or cool the large J6P cab quickly.

منطق الخدمة: هذا عاصي’ هو “dashboard-out” job to replace. A failure here is a major service event, often due to a leaking heater core (smell of coolant in the cab, fog on the windshield) or a refrigerant leak from the evaporator core. It is mounted using hardware like the M6 bolts (علامة 2).

جوهر 2: ال “التحكم في النظام” منطق (The Head Unit)

هذه هي “العقول” and user-interface components of the معدات تكييف الهواء فاو J6P.

1. عنصر: ‘Automatic A/C Control Mechanism Assy’ (8112010-B27-C00) – الكمية 1
هذا (علامة 18) is the climate control “head unit” in the dashboard. This is the electronic module with the buttons, dials, and screen that the driver interacts with.

ال “Automatic” منطق: As an “Automatic” وحدة, it houses a microcomputer. The driver sets a target temperature (على سبيل المثال, 22درجة مئوية). The computer then takes inputs from in-cab and ambient temperature sensors and automatically controls the blend doors, سرعة المروحة, and A/C compressor to maintain that temperature perfectly.

منطق الواجهة: This unit controls all functions: درجة حرارة, سرعة المروحة, airflow mode (على سبيل المثال, defrost, face, foot), and A/C compressor on/off. A failure here (على سبيل المثال, dead screen, non-responsive buttons) can render the entire معدات تكييف الهواء فاو J6P useless.

2. عنصر: ‘A/C Usage & Maint. Warning Label (Chinese/English)’ (8100201AA01J) – الكمية 1
هذا (علامة 17) is a mandatory information label, typically placed in the engine bay or on the HVAC box.

منطق الخدمة: This label’s logic is to inform the technician. It provides the most critical information needed to service the معدات تكييف الهواء فاو J6P: the exact *type* of refrigerant (على سبيل المثال, R134A), the system’s *capacity* (على سبيل المثال, 850g), and the specific *type* of compressor oil to use (على سبيل المثال, PAG 46). Using the wrong information will destroy the system.

جوهر 3: ال “Air Filtration” منطق (The Cabin Filter)

This is one of the most important service items in the entire معدات تكييف الهواء فاو J6P, especially for a dump truck.

1. عنصر: ‘External Air Filter Assy’ (8101570-B27) – الكمية 1
هذا (علامة 4) is the cabin air filter assembly. It is the first line of defense for all air entering the cab.

The Filtration Logic: This assembly contains a replaceable, pleated filter element. Its job is to trap all airborne contaminants *before* they enter the HVAC unit. For a CA3250P66K2L1T1E operating in dusty quarries or construction sites, this means trapping massive amounts of silica dust, حبوب اللقاح, soot, and road grime.

The Health Logic: This filter directly protects the driver’s respiratory health, ensuring the air inside the cab is clean, even when the air outside is hazardous. Many versions are also “charcoal-activated” to filter out exhaust fumes and odors.

The System Protection Logic: This filter is also critical for the health of the معدات تكييف الهواء فاو J6P. It prevents the high-density fins of the evaporator core (جوهر 1) from becoming caked in a “blanket” of dust, which would block all airflow, cause the system to freeze over, and lead to total failure.

منطق الخدمة: A clogged filter is the #1 cause of “poor A/C performance” أو “low airflow.” This filter is a regular maintenance item and must be replaced often. It is held in place by its own housing, which is secured by nuts (علامة 6) وغسالات (علامة 5).

جوهر 4: ال “Air Distribution” منطق (Ducting)

This group of components forms the “delivery network,” channeling the conditioned air from the main HVAC unit (جوهر 1) to the driver and passenger.

1. عنصر: ‘Driver Foot Air Duct Assy’ (8101160-أ01) – الكمية 1
هذا (علامة 7) is the molded plastic duct that directs air specifically to the driver’s footwell.

2. عنصر: ‘Passenger Foot Air Duct Assy’ (8101185-B27-C00) – الكمية 1
هذا (علامة 8) is the corresponding duct for the passenger’s footwell.

ال “Air Delivery” منطق: ال معدات تكييف الهواء فاو J6P relies on these ducts to transport air efficiently. They are designed to fit within the extremely tight confines of the dashboard, routing around steering columns and electrical boxes.

ال “آسسي” منطق: They are ‘Assemblies’ because they are not just hollow tubes. They include foam-gasket seals at their connection points. These seals are critical. They prevent the conditioned air from leaking out behind the dash, ensuring maximum airflow and pressure reaches the vents.

منطق الخدمة: These ducts are held in place by tapping screws (علامة 9). A common fault is a “rattle” if a duct comes loose, أو “poor airflow” if a foam seal has degraded.

جوهر 5: ال “Water Management” منطق (The Drain System)

This is one of the most simple, yet most critical, sub-systems of the معدات تكييف الهواء فاو J6P. Failure here leads to major interior damage.

1. عنصر: ‘Drain Hose’ (8107066-أ01) – الكمية 1
هذا (علامة 10) is a flexible rubber hose. Its sole job is to drain the condensation (ماء) that the evaporator core (جوهر 1) pulls from the air.

2. عنصر: ‘Drain Hose Grommet’ (8107047-أ01) – الكمية 1
هذا (علامة 11) is the rubber grommet that provides a perfect seal as the drain hose passes through the cab’s firewall to the outside. This prevents fumes, ضوضاء, and engine heat from entering the cab.

3. عنصر: ‘Drain Hose Mounting Bracket’ (8100106-أ01) – الكمية 1
هذا (علامة 14) is a steel bracket that secures the hose.

4. عنصر: ‘Plastic Strap’ (ت67414646) – الكمية 1
هذا (علامة 16) is a plastic zip-tie, used with the bracket to clamp the hose in place.

ال “Routing” منطق: This system is critical. The bracket and strap ensure the hose has a constant downward slope and is routed safely, away from hot exhaust manifolds (which would melt it) or spinning shafts.

The Failure Logic: This is a top-tier diagnostic item for any معدات تكييف الهواء فاو J6P. If this hose becomes clogged (by spiders, الطين, or debris), the water *will* back up. The HVAC box will fill with water and overflow, pouring into the passenger footwell. This soaks the carpet, destroys electronic control modules, and causes a severe mold/mildew problem.

جوهر 6: ال “قفل & تصاعد” منطق (الأجهزة)

This diverse group of hardware is used to mount all the components of the معدات تكييف الهواء فاو J6P.

1. عنصر: ‘Hex Head Bolt’ (CQ1500620) – الكمية 3
2. عنصر: ‘Large Washer’ (Q40206) – الكمية 3
هذا (علامة 2 & 15) M6 bolt and large washer combination is likely used to secure the main ‘Two-Box Assy’ (جوهر 1) to the dashboard’s structural frame. The large washer distributes the load.

3. عنصر: ‘Hex Nut’ (CQ34008) – الكمية 4
4. عنصر: ‘Washer’ (Q40108) – الكمية 4
هذا (علامة 6 & 5) M8 nut and washer set is used to secure the ‘External Air Filter Assy’ (جوهر 3) to its mounting studs.

5. عنصر: 'برغي التنصت على رأس الوعاء المتقاطع’ (CQ2714219) – الكمية 4
6. عنصر: 'برغي التنصت على رأس الوعاء المتقاطع’ (CQ2714813) – الكمية 2
هؤلاء (علامة 3 & 9) are self-tapping screws. Their logic is to fasten plastic components, such as the air ducts (جوهر 4), directly to plastic mounting bosses. They are fast to install and vibration-resistant.

7. عنصر: "الترباس المختلط."’ (CQ1460820) – الكمية 2
8. عنصر: ‘Hex Flange Nut’ (CQ39606) – الكمية 2
هذا (علامة 13 & 12) M8 combination bolt and flange nut set is likely used to secure the ‘Drain Hose Mounting Bracket’ (جوهر 5) to the chassis. ال “combination” و “شفة” features are both designed to resist loosening from vibration.
