Air Brake Compressor 4946291/5286964 for Cummins

Description

Cummins engine system Double-Cylinder Air Brake Compressor 4946291/5286964:

Cummins engine system air brake compressor 4946291/5286964 is an air compression equipment specially designed for heavy truck engine systems. It plays a crucial role in the heavy truck field. Its core consists of two cylinders. Compared with single-cylinder air compressors, the double-cylinder design can output a larger pumping volume. This feature enables it to fully meet the higher energy consumption requirements of heavy truck engine systems during operation. It provides compressed air for the braking system, clutch system, etc. of heavy trucks to ensure the matching of pressure, flow rate and engine power.

Working principle of the double-cylinder air brake compressor 4946291/5286964:

The coordinated cooperation between the cylinder and the piston, through three closely connected processes of suction, compression and exhaust, cycle repeatedly to achieve efficient compression of air.

During the suction stage, the piston moves downward, the space inside the cylinder increases, the air pressure drops, and the outside air enters the cylinder under the action of pressure difference; during the compression stage, the piston moves upward, the space inside the cylinder decreases, and the air is gradually compressed, with the pressure continuously rising; during the exhaust stage, when the pressure of the compressed air reaches the set value, the exhaust valve opens, and the compressed air is discharged into the air reservoir to provide stable air source power for the air supply systems of vehicle braking, suspension, etc.

Structural features of the double-cylinder air brake compressor 4946291/5286964:

The uniqueness of this double-cylinder air compressor lies in its dual-cylinder structure. Each cylinder operates independently, enabling simultaneous compression work to enhance compression efficiency and meet the urgent gas demand of vehicles. It can also work alternately, evenly distributing the load among the cylinders and effectively reducing the working intensity of a single cylinder. This innovative design not only significantly improves the overall compression efficiency but also significantly extends the service life of the air compressor, enhances the reliability and stability of equipment operation, reduces the downtime for vehicle maintenance due to equipment failures, and lowers the usage cost for users.

Application scenarios and vehicle models for the double-cylinder air brake compressor 4946291/5286964:

The portable air brake compressor 4946291/5286964 boasts outstanding performance and is widely used in heavy trucks, engineering vehicles, and construction machinery. In terms of vehicle model compatibility. In terms of engine system compatibility, it can be stably matched with mainstream engine brands such as FAWDE, Shangchai, Weichai, and SINOTRUK engine system, ensuring stable and reliable air compression output for vehicles under various complex working conditions. It is one of the very important accessories in the power system of heavy trucks.

Common faults and maintenance for air brake compressor 4946291/5286964:

1. Insufficient exhaust volume: Due to long-term use, the piston rings are worn out and the sealing performance of the intake valve is poor. Regularly check the sealing of the air storage tank to prevent aging and other problems.
2. Oil leakage or air leakage: The sealing ring is aged, or the interface at the intake or exhaust port is loose. This is the most common problem. Replacing the aged sealing ring can solve the problem.
3. Abnormal noise: Check if the connecting rod bearing is worn out, and if the clearance of the piston pin is normal.

It is recommended to inspect the piston rings, seals, etc. of the air compressor every 50,000 kilometers. Replace the air compressor lubricating oil with national standards.‌
