Large fluctuations in the drum liquid level
Thread Content
The liquid level in a double-chamber balanced drum fluctuates greatly, especially under the influence of pressure; when pressure decreases, the drum’s liquid level rises, while it drops when pressure increases. What is the reason for the basically stable liquid level control on site?
Although the pressure changes, the liquid level in the drum remains within normal ranges.
It is suspected that there are bubbles in the connection tube between the dual-chamber balancer and the transmitter; try to completely remove those bubbles.
The working principle of the boiler’s drum determines that pressure increases while the liquid level decreases, and that pressure decreases while the liquid level increases. Understanding the working principle of the drum will make it clear.
