Brief Introduction to Bks Diaphragm
The diaphragm of a breaker, also known as a crushing chamber diaphragm or simply a diaphragm, is a crucial component within the crusher that plays a vital role in the crushing process. It is typically located within the crushing chamber and serves as a barrier or separator between different areas of the chamber. The primary function of the diaphragm is to protect the internal components of the crusher from excessive wear and damage caused by the abrasive materials being crushed. The diaphragm is made from durable materials that can withstand the rigorous conditions within the crushing chamber.
Benefits of Bks Diaphragm
Durability and Resistance
Diaphragms made of materials like PU rubber are designed to withstand the harsh conditions and heavy loads encountered in breaking or crushing operations. They are resilient and can resist abrasion, chemicals, and temperature fluctuations, ensuring longer service life and reduced maintenance requirements.
Isolation and Sealing
The diaphragm acts as a barrier, effectively sealing the interior of the breaker from the exterior environment. This prevents dust, debris, or other contaminants from entering the mechanism, protecting the internal components and ensuring smooth operation.
Pressure Equalization
In some types of breakers, the diaphragm helps to equalize pressure between different chambers or compartments. This prevents excessive pressure build-up that could damage the equipment or affect its performance.
Shock Absorption
The diaphragm's flexibility allows it to absorb shocks and vibrations that occur during the breaking process. This reduces stress on the other components of the breaker, minimizing wear and tear and extending the overall lifespan of the equipment.
Efficient Energy Transfer
By effectively transmitting force and pressure, the diaphragm ensures that the breaking action is efficiently and uniformly applied to the material being crushed. This enhances the efficiency and productivity of the breaker.
Smooth Operation
The diaphragm's flexible nature allows it to adapt to changes in pressure and force during the breaking process. This ensures a smooth and consistent operation of the breaker, minimizing any jerky or irregular movements that could affect performance or safety.
The Common Applications of Bks Diaphragm
Energy Transfer and Conversion
The diaphragm, as a key component in the hydraulic system, can effectively transmit and convert hydraulic energy. When the pressure in the hydraulic system acts on the diaphragm, the diaphragm will deform and push crushing components such as breaker hammers or crushing blades to work, thereby crushing the material.
Cushioning and Shock Absorption
The diaphragm plays a buffering and shock-absorbing role in the hydraulic crusher. During the crushing process, the hydraulic crusher will produce vibration and impact due to the impact force of the breaker hammer and the reaction force of the material. The elasticity and damping properties of the diaphragm can effectively absorb and disperse these impact energies, reduce the impact of vibration on the crusher and surrounding equipment, and improve the stability and reliability of the equipment.


Control Crushing Force
The design and material selection of the diaphragm can affect the crushing force and control method of the hydraulic breaker. By adjusting the thickness, hardness and other parameters of the diaphragm, precise control of the crushing force can be achieved to adapt to different materials and crushing requirements. This helps protect the material from over-crushing and achieves ideal crushing results.
Sealing and Isolation
The diaphragm can also play the role of sealing and isolation in the hydraulic crusher. It can prevent oil leakage in the hydraulic system and maintain the normal operation of the hydraulic system. At the same time, the diaphragm can also isolate the crushing components and the hydraulic system, prevent materials from entering the hydraulic system, and protect the safe and stable operation of the hydraulic system.
How to Select Diaphragm?
Material Considerations
Durability and Resistance: Choose a diaphragm material that can withstand the abrasive, corrosive, and high-pressure conditions of the breaking process. Common materials include polyurethane (PU) rubber, which offers good abrasion resistance and flexibility.
Temperature Resistance: Consider the operating temperature range of the breaker and select a diaphragm material that can handle these temperatures without degrading or becoming brittle.
Size and Compatibility
Breaker Model and Size: Ensure that the diaphragm is compatible with the specific model and size of the breaker. Measure the dimensions of the breaker's chamber or mounting area to ensure a proper fit.
Mounting Configuration: Check the mounting configuration of the diaphragm, including the attachment points and fasteners. Ensure that the diaphragm can be securely mounted without any interference or clearance issues.
Performance Characteristics
Pressure Rating: Determine the maximum operating pressure of the breaker and select a diaphragm with a suitable pressure rating. The diaphragm should be able to handle the pressure without rupturing or deforming.
Shock Absorption: Look for diaphragms that offer good shock absorption capabilities to reduce vibrations and stress on the breaker's components.
Sealing Properties: Ensure that the diaphragm provides a tight seal to prevent dust, debris, or fluids from entering the breaker's interior.
Cost and Availability
Cost-Effectiveness: Compare prices of different diaphragms to find a cost-effective option that meets your performance requirements. Consider the long-term value and durability of the diaphragm in relation to its initial cost.
Availability and Supply Chain: Check the availability of the diaphragm and ensure a reliable supply chain to minimize downtime and operational disruptions.
