Will the pressure difference of a dual chamber equilibrium container be easily affected?-Chemical Instrument Network

Dual chamber balanced containerWhen used in conjunction with a water level indicator or differential pressure transmitter, it can monitor the water level of the steam drum during boiler start-up, shutdown, and normal operation, and output pressure difference (AP) signals when the water level changes to ensure the safe operation of the boiler.

Structural characteristics:

Dual chamber balanced containerComposed of pipes (Φ 16 × 3), bent pipes (Φ 16 × 3), water cups, funnels, etc., due to the simultaneous heating of pipes and bent pipes by saturated steam, the weight of water in the positive pressure compensation pipe is approximately equal to the weight of saturated water at the corresponding steam drum pressure in any case. At the same time, due to the correct selection of the height of the positive pressure compensation tube, regardless of how the pressure inside the steam drum changes, the pressure change values of the positive pressure compensation tube and the negative pressure tube are equal.
Therefore,Dual chamber balanced containerThe pressure difference generated remains unchanged. The water level indicated by the low-end water level gauge remains unchanged. In addition, due to the equal temperature of water in a section of positive and negative pressure pipes introduced from the equilibrium container, although affected by the steam drum press and room temperature changes, their changes are equal.
