Bucket Cylinder for Doosan Middle Excavator DH200-5-7

Introduction

A bucket cylinder is a specially designed hydraulic cylinder that is primarily used to control the movement of the bucket in heavy machinery such as excavators, backhoe loaders, 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 handle heavy loads efficiently and adapt to complex work environments and diverse job requirements.

Features

• High Strength and Durability

  The bucket cylinders are typically made of high-strength steel or aluminum, which can withstand high pressure and heavy loads, adapting to harsh working conditions. The design considers wear resistance and corrosion resistance, extending the service life.

• Efficient Hydraulic Operation

  The hydraulic pressure is used to achieve smooth extension and contraction actions, allowing for quick response to control commands, providing powerful push-pull forces, and suitable for handling heavy loads and complex job tasks.

• Various Types

  The bucket cylinders can be single-acting (using hydraulics in only one direction) or double-acting (using hydraulics in both directions) depending on the operation requirements. Some models are telescopic, allowing for greater extension without increasing the external dimensions, making them suitable for limited space applications.

• Perfect Substitute

  Our products can perfectly replace these hydraulic cylinders.

Applications

The bucket cylinders are widely used in various machinery, such as:

• Construction Equipment

  In excavators, they are essential for digging, loading, and moving soil or debris. In backhoe loaders, the bucket cylinder helps with both digging and lifting.

• Agricultural Machinery

  Used in front-end loaders for scooping, lifting, and transporting soil, hay, and other materials.

• Excavators

  The bucket cylinder allows for penetration of the soil to achieve excavation.

• Loaders

  In front-end loaders, they help with lifting and dumping goods effectively.

Design Considerations and Selection Criteria

• Bearing Capacity

  The cylinder must have sufficient bearing capacity to ensure safe operation and prevent overloading.

• Sealing

  The piston seal, rod seal, and other seals must be made of wear-resistant materials such as polyurethane and nitrile rubber to prolong the service life.

• Durability

  The cylinder body and thread end surface must undergo fine processing to improve wear resistance.

• Safety

  The cylinder must be equipped with safety devices to prevent accidents caused by sudden pressure drops or excessive loads.

• Maintainability

  The cylinder must be easy to disassemble and assemble, replace damaged parts, and maintain.

Sealing and Lubrication

Various sealing components such as piston seals and rod seals are used to prevent oil leakage and ensure the lubrication of moving components. The seals are made of wear-resistant materials such as polyurethane and nitrile rubber, and the cylinder body and thread end surface are finely processed to improve wear resistance. The cylinder also needs to be regularly filled with a suitable amount of hydraulic oil for lubrication.

Inspection and Preventive Maintenance Measures

Regular inspections, appropriate lubrication, seal replacement, and calibration checks are common maintenance tasks. Proper installation, lubrication, and adjustment are essential, and correct alignment of the cylinder should be provided during installation. It is recommended to use appropriate installation brackets to secure the cylinder. The recommended inspection, repair, and replacement procedures are provided, along with tips for extending the service life of the cylinder.

Safety Considerations and Environmental Factors

Safety measures are crucial when using the cylinder. It is necessary to ensure that the cylinder is installed and used correctly to prevent accidents. Environmental factors such as temperature, pressure, and humidity must also be considered to prevent potential safety hazards.

Common Fault Diagnosis and Solutions

Common faults such as oil leakage, insufficient pressure, and unstable operation may occur during the use of the cylinder. The cylinder’s manual provides troubleshooting tips and solutions to help readers diagnose and solve problems effectively, and preventive measures to reduce potential issues.
