Auto Ac Conditioning Compressor For Nissan Livina OEM 926001JY7A 92600CJ73D 926003RJ0A Compressor Assembly

Compatible model: Specifically designed for the 2009 Nissan Livina, it can achieve a good match with the air conditioning system of this model, ensuring the stable operation of the system.
Working principle: The compression of the refrigerant is achieved based on the reciprocating motion of the piston within the cylinder. Its working process consists of four strokes: intake, compression, exhaust and power generation. During the intake stroke, the piston moves downward, the intake valve opens, and the refrigerant gas enters the cylinder. During the compression stroke, the piston moves upward, compresses the refrigerant gas, and the intake valve closes. During the exhaust stroke, the piston moves downward again, the exhaust valve opens, and the high-pressure refrigerant gas is discharged. During the power stroke, the piston moves upward to complete one working cycle.

Product characteristics

Refrigeration performance: It has a strong refrigeration capacity and can lower the temperature inside the vehicle in a short time. Through the efficient movement of the piston, the refrigerant can be rapidly compressed, enabling the air conditioning system to cool down quickly and creating a comfortable environment inside the vehicle. Even in hot weather, it can remain cool.
Stability: The structure is relatively simple, with fewer components. It has been carefully designed and manufactured, and operates stably and reliably. Under normal use and maintenance conditions, it can work stably for a long time and reduce the probability of faults occurring.
Durability: The key components are made of high-strength and wear-resistant materials, capable of withstanding significant pressure and friction, offering excellent durability and extending the service life of the compressor.
Noise and vibration: A series of measures have been taken during the design and manufacturing process to reduce noise and vibration. For instance, the movement trajectory and balance performance of the piston have been optimized, reducing the vibration and noise generated by the piston's movement and providing a quiet driving and riding environment inside the vehicle.

Common faults and causes

Poor cooling effect: It might be due to refrigerant leakage, resulting in insufficient refrigerant in the system and affecting the cooling effect. It could also be that the piston rings are severely worn, which deteriorates the sealing performance of the cylinder and reduces the compression efficiency. In addition, faults in the intake valve or exhaust valve, such as not closing tightly, can also lead to insufficient compression of the refrigerant and a decrease in the cooling capacity.
Abnormal noise from the compressor: If the gap between the piston and the cylinder wall is too large, it will produce knocking sounds during movement. Wear or loosening of the crankshaft connecting rod mechanism can also cause abnormal noise. In addition, damage to the bearings inside the compressor can also cause abnormal noise.
The compressor does not work: Electrical system faults, such as blown fuses, damaged relays, or open circuits, will prevent the compressor from obtaining power. The pressure switch malfunctioned and failed to correctly feedback the system pressure information, resulting in the compressor being unable to start normally. It could also be a mechanical fault inside the compressor, such as a jammed piston, etc.
