Product Specification

OEM HB20G Hydraulic Breaker Parts Wedge Type Excavator Rock Breaker Chisel

Product Introduction

The diaphragm membrane is an essential part of hydraulic breakers, engineered to effectively separate hydraulic fluid from the air chamber inside the breaker. This crucial component helps absorb shocks, minimize vibrations, and safeguard internal parts from wear and damage. By ensuring stable operation and prolonging the life of hydraulic breakers, the diaphragm membrane enhances both performance and durability in demanding construction and demolition environments.

Parameter

Key Features

Material: Crafted from high-quality rubber compounds and enhanced with materials such as PU, TFP, FKM, and NBR, the diaphragm membrane offers superior durability, excellent oil resistance, and outstanding high-temperature performance.

Temperature and Pressure Range: Engineered to operate reliably in temperatures ranging from -35°C to 135°C, this diaphragm is suitable for high-pressure environments with ratings typically between 85-125 MPa.

Extended Service Life: Built for longevity, the diaphragm membrane can withstand over 1 million operational cycles, ensuring dependable performance and reducing the need for frequent maintenance.

Noise and Dust Reduction: Designed for optimal operation, the diaphragm effectively reduces noise levels and controls dust and debris, contributing to a cleaner and quieter work environment.

Applications 

• Construction Applications:
  Ideal for breaking concrete, asphalt, and rocks, hydraulic breakers are widely used in demolition and excavation projects to facilitate efficient material removal and site preparation.

  Mining Operations:
  Hydraulic breakers are essential tools in both underground and open-pit mining, delivering powerful performance for breaking hard rocks and other tough materials, improving productivity and safety in mining environments.

  Demolition Projects:
  Perfect for dismantling buildings and infrastructure, hydraulic breakers enable the efficient breakdown of large debris and structures, streamlining the demolition process and reducing project timelines.

PRODUCTION PROCESS

Through/Side/Bolt:
Manufactured from premium 42CrMo steel, these bolts are available in both 10.9 and 12.9 grade for superior strength. Each bolt undergoes a rigorous heat treatment process, including quenching and tempering, followed by surface treatments such as natural color or black coating. The result is enhanced durability and corrosion resistance, ensuring reliable performance in demanding applications.

Mounting Pin:
Crafted from robust 42CrMo material, the mounting pin is produced through a hardening and tempering process, followed by precision machining, mid-frequency induction hardening, and external diameter grinding. The quenching depth reaches 3mm, providing a hard surface and exceptional wear resistance for long-lasting durability in hydraulic breaker operations.

Precision-Checked Piston:
Engineered from high-quality 20CrMo steel, the piston undergoes comprehensive thermal treatments including overall carburizing and quenching. Advanced grinding technology ensures high surface precision and smoothness. This allows hydraulic oil to form a consistent oil film, delivering excellent lubrication, abrasion resistance, and extended piston lifespan while maintaining optimal impact force.

Inner Bush:
Made from either 42CrMo or 20CrMo, the inner bush is forged, precision machined, carburized, quenched, and finely ground. These processes result in high product accuracy and outstanding resistance to wear, ensuring stable operation in hydraulic breakers.

Front Cover:
Constructed from 42CrMo or 20CrMo steel, the front cover is forged, precision machined, and undergoes carburizing heat treatment followed by fine grinding of the assembly surface. This provides superior wear resistance and impact protection, enhancing the service life and reliability of the hydraulic breaker.
