What is a Cylinder and Why It Matters in Hydraulic Breakers

Hydraulic breakers are a crucial piece of equipment in demolition, mining, and construction. Yet, most operators ignore the factor that truly affects performance and durability: the cylinder, or the “heart” of the breaker. How it operates, what it is made of, and how it should be maintained will enable you to achieve maximum efficiency, minimize downtime, and keep your investment safe.

Understanding the Cylinder

The cylinder is the core component of the breaker. It is consisted of the main body, piston, piston rings, valve, and main seals. METDEEM‘s cylinders are made of 20CrMo alloy steel, and undergo heat treatment process providing exceptional stability, wear resistance, and long-term durability.

Why It’s the Heart of the Hydraulic Breaker

A high-precision cylinder can make the breaker working more efficiently, reliably, and durable. In essence, the cylinder makes the breaker perform like a well-designed engine.

Key Functions of the Cylinder

Power output

The piston translates hydraulic pressure into kinetic energy. Smooth, precise piston motion with low friction and minimal seal wear is provided by the cylinder. METDEEM pistons are ground and polished to fine tolerances for maximum energy transfer.

Pressure Bearing and Load Distribution

Under load, the cylinder resists very large internal pressure. Forging strengthens its molecular construction, and heat treatment creates a hardened surface layer (1-1.5mm thick), which is resistant to cracking and tough. This means that the cylinder can be repeatedly struck, and the load is evenly transferred to the internal components.

Sealing and Structural Support

The cylinder provides seal integrity at high pressure and avoids hydraulic leaks that have the potential to compromise safety or performance. Its design keeps the breaker aligned and stable regardless of extreme use.

METDEEM’s Engineering Excellence

Long Lasting Materials and Precision Design

We apply only good-quality material for the production of our breaker parts in METDEEM. The hammer’s cylinder is ground internally by a CNC grinder with a single clamping operation. It provides high internal control, concentricity, and surface finish, hence every product is a standard part. We produce our cylinders of 20CrMo alloy steel and heat-treat them for full hardness and wear resistance.

Manufacturing Standards of METDEEM

METDEEM hydraulic breakers are made with high-strength alloy steel with an advanced hydraulic system design to provide robust impact force, instant penetration, and good performance. Our stringent quality control procedures, from raw material testing to finished assembly, guarantee every unit meets international standards of dependability. We also feature models such as the DM05 Hydraulic breaker, which is suitable for 0.8 ton excavators with 35 mm chisels that incorporate our highly engineered cylinders.

Longevity and Resistance in Harsh Environments

Cylinders of this material show no microscopic deforming or cracking when put under load, which improves their life span. Such characteristics qualify our breakers for harsh environments like mining and demolition applications. Our products are specifically engineered to withstand more than 1,500 hours with regular maintenance.

Importance of Cylinder Quality

Effect of Performance on Hydraulic Breakers

An optimally designed cylinder impinges directly on the hydraulic breaker’s efficiency by limiting internal movement and providing maximum energy transfer efficiency. Under the same pressure and flow rate, our cylinders work faster and produce a higher impact force. This makes them more efficient, less wear and tear, and shorter work cycle, which means less operating cost.

Common Problems due to Low-Quality Cylinders

Poor-quality cylinders will crack with pressure, misalign when badly machined, or leak when badly sealed. Cylinders from this material are not subject to microscopic deformation or cracking under stress, unlike the less expensive types that quickly wear out.

Maintenance Tips to Extend Lifespan

To get them to last:

• Seals should be checked frequently for wear.
• Hydraulic fluid must be kept clean.
• Use recommended lubricants.
• Overloading or excessive recommended levels of pressure should be avoided.

Investment in a sturdy cylinder avoids such common malfunctions and conserves time and repair money.
