Bladder
A rubber bladder is an important industrial component that acts as a pressure storage tank. In this system, an incompressible liquid or fluid is pressurized by an external source.
Application of the bladder
The rubber bladder is actually designed to separate gas from liquid and is used in many industries. This part reacts to pressure fluctuations and prevents liquid from entering parts such as the compressor. Its installation location is usually in the suction line, between the operator and near the compressor.
Bladder function
The function of this part is that its inside is mainly saturated with nitrogen gas and its outer space is filled with oil. When the pressure decreases, the bladder fills the oil chambers and controls the pressure of the device by adjusting the amount of nitrogen gas. This feature improves the performance of hydraulic systems and prevents sudden pressure fluctuations.
The rubber bladder is sometimes mistakenly identified with the accumulator, while the accumulator is actually its protective metal chamber. In large industrial systems, the bladder plays a key role in regulating oil pressure.
Rubber bladder and its features in industry
✅ Filling the internal space of the chambers – This part is used to prevent fluid leakage and balance internal pressure.
✅ Easy installation on industrial equipment – The flexible design of the bladder makes it easy to install on various industrial bodies.
✅ Lightweight and portable – The low weight of this part makes it easy to move and install it in various devices.
✅ Resistant to corrosion and leakage – The materials used in the construction of the bladder are highly durable against decay and corrosive materials.
🔹 NBR – Resistant to industrial oils and high temperatures.
🔹 HNBR – Resistant to hydrogen gas and hot oils.
🔹 VITON – Resistant to chemicals, abrasion, solvents and high temperatures.
Depending on the type of application, choosing the right material for a rubber bladder is very important, as it improves the durability and performance of the devices.
The most important factors for evaluating the quality of rubber bladders
🔹 Raw material: Use of high-quality rubber for greater durability.
🔹 Thickness and strength: High resistance to pressure and impact.
🔹 Abrasion resistance: Reduces wear and increases lifespan.
🔹 Thermal stability: Maintains performance at high and low temperatures.
🔹 Chemical resistance: Not affected by oils, fuels, and corrosive substances.
Examining these factors helps in choosing a suitable and durable bladder.
