Balance Tank Pre-Pressure Adjustment: Correct Settings and Example Calculation. Learn how to adjust the pre-pressure of the balance tank with proper pump pressure values, tank selection, and accurate air pressure calculations.
Pressure Pre-Adjustment of the Balance Tank
The pre-pressure of the balance tank should be set lower than the booster pump's startup pressure (Halt). This adjustment ensures the system operates smoothly and prevents pressure fluctuations, leading to a longer lifespan and more efficient performance of the pump.
Selected Tank Specifications:
- Pressure Resistance: The tank should be selected based on the pump's Hmmax (pressure at Q=0). According to the example above, since the pump's Hmmax is 110 mSS, the tank should be of PN16 class.
- Tank Pressure Adjustment: Air pressure should be set slightly lower than the lowest pressure setting of the last activated pump to avoid undesired pressure increases.
According to the example above, air pressure should be set at 5.4 bar, which is lower than the lowest pressure value of 6 bar (60 mSS). Proper adjustment ensures the efficient and balanced operation of the booster system.
Tank Appearance:
- Pre-Pressurized Tank Appearance: The pressure level when the tank is empty.
- Tank Appearance in Operating Conditions: The pressure level under full operating conditions.
