Bem-vindo a esta desconstrução crítica do Tanque de armazenamento FAW J6P para o FAW Jiefang CA3250P66K2L1T1E 6×4 caminhão despejando. Este componente, also known as the Receiver Drier, is the A/C system’s primary filter and guardian. Este guia analisa o 2 key parts that form this essential assembly.
O Tanque de armazenamento FAW J6P (Receiver Drier) is a vital, non-negotiable component in the high-pressure liquid line of the air conditioning system. Its function is far more complex than a simple “tank.” It is a three-in-one device: it stores liquid refrigerant, it filters debris, e (o mais importante) it traps catastrophic moisture.
As shown in the parts diagram, o Tanque de armazenamento FAW J6P is not available as a separate part. It is integrated into the ‘Condenser with Receiver Drier Assy’ (8105010-70U). This modern, efficient design eliminates extra hoses and leak points. This teardown will analyze the logic of this integrated tank and its mounting system.
For a technician, o Tanque de armazenamento FAW J6P is a mandatory replacement item. Any time the A/C system is opened for service (Por exemplo, a hose or compressor replacement), this component *must* be replaced. We will explore why this is critical for the health of the compressor and the expansion valve.
This is the primary assembly that houses the Tanque de armazenamento FAW J6P. It is sold as one complete part, which is critical for service.
1. Componente: ‘Condenser with Receiver Drier Assy’ (8105010-70U) – Quantidade 1
Esse (Marca 1) is the complete assembly. The name (Condenser with Storage Tank Assembly) clearly states it is a Condenser *with* a Storage Tank. O Tanque de armazenamento FAW J6P (Receiver Drier) is the aluminum canister permanently attached to the side of the main condenser.
The Integration Logic: This modern design is for reliability. By manufacturing the Tanque de armazenamento FAW J6P as part of the condenser, the factory eliminates two high-pressure refrigerant hose connections. This reduces the number of potential leak points by half and simplifies the assembly process.
A lógica do serviço: This is the most important concept. A technician cannot buy the Tanque de armazenamento FAW J6P separately. If the tank’s desiccant is saturated or its internal filter is clogged, the *entire* 8105010-70U assembly must be replaced. This ensures a new, perfectly clean condenser is installed at the same time as the new filter/drier.
The first function of the Tanque de armazenamento FAW J6P is to act as a liquid “receiver.”
O “Receiver” Lógica: The tank is positioned in the “liquid line” of the A/C system (after the condenser). Its first job is to act as a buffer or reservoir for the liquid refrigerant.
O “Bubble-Free” Lógica: The A/C system’s expansion valve (TXV) is a precision device that can only function with a 100%, solid stream of liquid. If refrigerant *gas* (bubbles) hits the valve, it will “starve” o sistema. O Tanque de armazenamento FAW J6P ensures that there is always a reserve of solid liquid ready.
O “Pickup Tube” Lógica: To achieve this, o Tanque de armazenamento FAW J6P has an internal “pickup tube.” This tube extends from the *outlet* port down to the very *bottom* of the canister. This design ensures that it only ever draws refrigerant from the pool of liquid at the bottom.
This is the most critical function of the Tanque de armazenamento FAW J6P. Isto “dries” the refrigerant.
The Desiccant Logic: Inside the Tanque de armazenamento FAW J6P is a porous bag filled with a “desiccant.” This is a material with a high affinity for water (H2O), typically silica gel or zeolite. As refrigerant flows through the tank, it must pass through this desiccant bag.
O “Água” Lógica de falha: Moisture is the #1 killer of A/C systems. When moisture meets the TXV, it instantly freezes into an ice crystal, completely blocking the valve and stopping all cooling. This is the most common cause of “A/C stops cooling after 20 minutes.”
O “Acid” Lógica de falha: The second moisture-related failure is “hydrolysis.” When H2O mixes with R134a refrigerant and oil, it forms corrosive acids, which will eat the aluminum A/C components from the inside out. O Tanque de armazenamento FAW J6P prevents this.
O “Replacement” Lógica: The desiccant bag can only hold a fixed amount of water. It is *mandatory* to replace the Tanque de armazenamento FAW J6P (the entire 8105010-70U assembly) *any time* the system is opened for more than a few minutes. Failure to do so guarantees the new compressor or hose will fail prematurely.
The third and final function of the Tanque de armazenamento FAW J6P is to act as the system’s main debris filter.
O “Compressor Failure” Lógica: When an A/C compressor fails, it often “grenades,” sending thousands of tiny metal shavings (shrapnel) into the system. This debris is pushed into the condenser.
O “Filtro” Lógica: O Tanque de armazenamento FAW J6P contains one or more fine-mesh filter screens. Its job is to trap all of this circulating debris *before* it can travel to the next component: the Thermal Expansion Valve (TXV).
O “TXV” Lógica: The TXV is a precision valve with an opening (orifice) as small as a human hair. A single piece of compressor shrapnel will instantly and permanently clog this orifice, blocking all refrigerant flow. The filter in the Tanque de armazenamento FAW J6P is the last line of defense.
O “Black Death” Lógica: A clogged Tanque de armazenamento FAW J6P is a clear sign of “black death” (a compressor failure). In this scenario, the entire system is contaminated. A technician *must* replace the compressor, o Tanque de armazenamento FAW J6P conjunto (8105010-70U), and the TXV, and then flush all remaining hoses.
This hardware is all that holds the integrated condenser (which contains the Tanque de armazenamento FAW J6P) no lugar.
1. Componente: 'Parafuso Combinado’ (CQ1460820) – Quantidade 4
Esse (Marca 2) is a set of four identical M8 bolts. They are the structural fasteners for the 8105010-70U assembly.
O “Parafuso de combinação” Lógica: The name “Parafuso de combinação” means each bolt has a pre-installed, arruela cativa. This is a vibration-resistance and assembly-speed feature. A lavadora (likely a spring lock washer) prevents the bolt from backing out under the constant vibration of the diesel engine.
The Isolation Logic: These bolts are almost always used with (unlisted) rubber bushings or grommets. These rubber isolators absorb vibration, preventing it from fatiguing the condenser’s delicate aluminum tubes and the Tanque de armazenamento FAW J6P‘s welded joints.
A lógica do serviço: A loose condenser assembly will vibrate, which will quickly lead to a stress-fracture leak. A technician must ensure these four bolts are present and properly torqued.
