Overview of American Engineering Machine 3116 and 3126 Models

American engineering machine 3116 and 3126 models are widely used in construction, mining and transportation industries. These heavy machines operate for long periods of time in harsh environments and therefore require efficient and reliable lubrication systems to ensure their proper functioning. Efficient lubrication system can not only extend the life of equipment, but also reduce maintenance costs and improve work efficiency.

Types and specifications of high-performance oil pumps

For 3116 and 3126 models, there are four main oil pump models to choose from: 2W8092, 2W8091, 705403 and 4W223. These oil pumps use advanced manufacturing technology and high-quality materials to ensure excellent performance under harsh working conditions.

• 2W8092: Suitable for high load conditions, large flow and stable pressure.
• 2W8091: Suitable for medium load conditions, small size and easy installation.
• 705403: Suitable for long-term continuous operation, wear resistance and long life.
• 4W223: Suitable for low temperature start, fast preheating and reliable performance.

When selecting the appropriate oil pump model, it is necessary to comprehensively consider the specific working conditions, operating environment and personal needs of the equipment.

The working principle of the oil pump

The basic structure of the oil pump mainly includes three types: gears, blades and pistons. Among them, the gear pump is the most commonly used one. Through the rotation of a pair of meshing gears, the oil is sucked in from the oil inlet and then discharged from the oil outlet, thereby realizing the circulating flow of the oil. Vane pumps and piston pumps use the movement of vanes and pistons respectively to perform the same function.

The function of the oil pump is to transport the lubricating oil to all parts of the engine to form a protective film, reduce friction, take away heat, prevent wear, and ensure the normal operation of the equipment.

Installation procedure of oil pump

Before installing the oil pump, please make sure that all tools and accessories are ready, and follow the steps below:

1. Preparation: Turn off the engine, disconnect the power supply, and ensure safety.
2. Removing the old pump: Loosen the fixing bolts and carefully remove the old oil pump.
3. Install the new pump: Align the new oil pump with bolts, and be careful not to overtighten it.
4. Connect the oil pipe: Connect the oil inlet and outlet pipes to the oil pump to ensure that the interface is well sealed.
5. Commissioning and operation: Start the engine, observe whether the oil pump is working normally, and check for leaks.

Please pay attention to cleaning during installation to avoid dust and impurities entering the oil system and affecting the performance of the pump.

Maintenance of oil pump

In order to ensure the long-term stable operation of the oil pump, regular maintenance and maintenance are essential. Here are some common maintenance points:

• Clean the filter screen: Clean the filter screen of the oil pump regularly to prevent blockage.
• Change the oil: According to the requirements of the equipment manual, change the oil regularly to keep the oil clean.
• Check the seal: Check the seal of the oil pump regularly, and replace it in time if it is damaged.
• Check the wear: Check the internal parts of the oil pump regularly, and repair or replace it in time if abnormal wear is found.

Through the above measures, the service life of the oil pump can be effectively extended and the failure rate can be reduced.

Troubleshooting and Problem Resolution

Although the quality of the oil pump is reliable, some failures may still occur during use. The following are several common fault phenomena and solutions:

• Noise: It may be caused by bearing wear or lack of oil. Check and replace the bearing or add oil.
• Low pressure: It may be that the filter screen is blocked or there is air in the pump body. It is necessary to clean the filter screen or exhaust.
• Leakage: It may be that the seal is aging or improperly installed, and the seal needs to be replaced or reinstalled.

When encountering problems, timely diagnose and take corresponding measures to quickly restore the normal working state of the oil pump.
