Generally bladder tank is a specialized container that is designed to store liquids while maintaining consistent and internal pressure. They operate based on a simple and yet effective mechanism that involves a flexible membrane and a surrounding air or gas chamber. In this blog we will be giving a detailed guide about how actually a bladder tank works, so let us get started!

Structure of a Bladder Tank

Primarily a bladder tank is made up of three major components:

• Outer shell which is a rigid or flexible steel, rubber or reinforced polymer is believed to give structural strength.
• Bladder that works to expand and shrink depending on the amount of liquid
• Air or Gas Chamber, which is the region around the bladder, is typically filled with air or gas which in turn pressurizes inside the tank

Working Mechanism of a Bladder Tank

Filling Process

• When liquid flows into the bladder tank, it enters it thus it expands.
• As the bladder expands, it pushes against the surrounding air or gas chamber that increases the internal pressure.
• This pressurizing force continues until the tank fills to full capacity or to the set pressure limit.

Maintaining Pressure

• The compressed air or gas provides a force against the liquid that helps in maintaining pressure inside the tank.
• This pressure keeps the liquid consistent with no changes, thus making it easily accessible for use.

Discharge Process

• When the outlet valve is opened, this pressurized air or gas exerts force on the bladder, thereby pushing the liquid out of the discharge line.
• The bladder contracts as the liquid exits, allowing the air or gas to expand and maintain consistent pressure until the bladder is empty.

Refilling and Pressure Adjustment

• Once the liquid level decreases, the air or gas pressure reduces automatically.
• Thebladder tank then can be refilled and this is how the cycle repeats which helps in maintaining a steady pressure throughout the operation.

Key Considerations to Look in a Bladder Tank

• Severe temperatures may impact the material of the bladder, leading to hardening, cracking or loss of flexibility. Keep an eye on temperature conditions to avoid premature wear.
• Make sure the bladder material is compatible with the particular liquid being stored to avoid chemical reactions, degradation, or contaminations.
• Fit a pressure-relief valve to overcome problems such as over pressurization, because if not regulated it could damage the bladder and make it unsafe.
• Undergo a routine inspection of the bladder and its outer shell so that any signs of leaks, wear or damage can be detected at the earliest.
