Bucket Cylinder For Doosan Large Excavator DH290

Introduction

The bucket cylinder for Doosan large excavator DH290 is a specially designed hydraulic cylinder used to control the movement of the bucket in heavy machinery such as excavators, backhoe excavators, and front-end loaders. Its main function is to enable the bucket to lift, lower, and tilt, making it easier to handle various material handling tasks. In the hydraulic system, the bucket cylinder controls the precise movement of the bucket through changes in hydraulic oil pressure, allowing operators to efficiently handle heavy loads and adapt to complex work environments and diverse job requirements.

Features

• High Strength and Durability

  The bucket cylinder is usually made of high-strength steel or aluminum, which can withstand high pressure and heavy loads, adapt to harsh working environments, and is designed with wear resistance and corrosion resistance in mind to extend its service life.

• Efficient Hydraulic Operation

  The bucket cylinder uses hydraulic oil pressure to achieve smooth extension and contraction, responds quickly to control commands, provides powerful pushing and pulling force, and is suitable for handling heavy loads and complex job tasks.

• Various Types

  The bucket cylinder can be selected as a single-acting (hydraulic is used in only one direction) or double-acting (hydraulic is used in both directions) cylinder according to requirements, and some models are telescopic, allowing for greater extension without increasing external dimensions, suitable for applications with limited space.

• Perfect Replacement

  Our product can perfectly replace these hydraulic cylinders.

Applications

The bucket cylinder is widely used in various heavy machinery, including:

• Construction Equipment

  In excavators, they are vital for digging, loading, and moving soil or debris. In backhoe excavators, the bucket cylinder helps with digging and lifting. In front-end loaders, they facilitate lifting and tilting of goods effectively.

• Agricultural Machinery

  Used for front-end loaders, picking up, lifting, and transporting soil, hay, and other materials.

• Excavators

  The bucket cylinder enables the bucket to penetrate the soil to achieve digging action.

Design Considerations and Selection Criteria

The design of the bucket cylinder considers its load-bearing capacity, sealing, durability, safety, and maintainability. The following are the key design considerations:

• Load-Bearing Capacity

  The bucket cylinder is designed and manufactured to withstand the maximum force and weight required for its intended application.

• Sealing

  The bucket cylinder uses various sealing components, such as piston seals, rod seals, etc., with wear-resistant materials such as polyurethane and nitrile rubber, to ensure a good seal and prevent fluid leakage.

• Durability

  The cylinder body and threaded end surface are finely processed to increase wear resistance. The bucket cylinder is also designed with corrosion-resistant materials and coatings to extend its service life.

• Safety

  The bucket cylinder is equipped with safety devices such as relief valves and overload protection to prevent injury or damage to the cylinder or machinery.

• Maintainability

  The bucket cylinder requires regular inspection and preventive maintenance to ensure optimal performance. The hydraulic oil needs to be changed and refilled regularly, and the seal needs to be inspected and replaced if necessary.

Sealing and Lubrication

The bucket cylinder uses various sealing components, such as piston seals, rod seals, etc., with wear-resistant materials such as polyurethane and nitrile rubber, to ensure a good seal and prevent fluid leakage. The cylinder body and threaded end surface are finely processed to increase wear resistance. It needs to be regularly lubricated with the appropriate amount of hydraulic oil to maintain optimal performance.

Maintenance and Repair

The following are some common maintenance tasks for the bucket cylinder:

• Regular Inspection

  The bucket cylinder needs to be regularly inspected to ensure that it is working properly and to detect potential problems early.

• Lubrication

  The bucket cylinder needs to be lubricated with the appropriate amount of hydraulic oil to maintain optimal performance.

• Seal Replacement

  The seal needs to be inspected and replaced if necessary to maintain a good seal and prevent fluid leakage.

• Alignment Check

  During installation, the bucket cylinder needs to be aligned correctly to ensure that it is working properly.

Proper installation, lubrication, and adjustment are essential to ensure the longevity of the bucket cylinder. The use of appropriate installation brackets is recommended to secure the cylinder. We provide a recommended inspection, repair, and replacement procedure to extend the life of the bucket cylinder.

Safety Considerations and Environmental Factors

When using the bucket cylinder, it is essential to follow appropriate safety procedures to prevent injury or damage to the cylinder or machinery. Regular inspection, maintenance, and repair can help reduce potential environmental hazards.

Troubleshooting and Common Problems

The following are some common problems that may occur with the bucket cylinder:

• Leakage

  The cylinder may leak due to damaged seals, contaminated hydraulic oil, or loose connections.

• Slow Operation

  The cylinder may operate slowly due to insufficient hydraulic oil, worn seals, or damaged rods.

• Overheating

  The cylinder may overheat due to low oil levels, blocked oil passages, or damaged relief valves.

To solve these problems, it is necessary to identify the cause and take appropriate corrective action, such as replacing damaged seals, cleaning the hydraulic oil, or repairing or replacing damaged parts.
