Self-Checking Low Water Деңгей реттегіші

Regarding the operation and the controlling of the өндірістік қазандар, rules and regulations are subject to change due to country’s Қолданылуы. Nevertheless, it is clearly shown in the regulations that өндірістік қазандар should be operated safely without the assistance of a person when there is high-safety concern

It can be extremely dangerous to operate өндірістік қазан without water. Due to the high pressure inside of the өндірістік қазан, water vapour will expand and apply forces on the өндірістік қазан’s walls. When the design limit is exceeded, the explosion might occur. If the water level drops to the pre-set low level, the Деңгей реттегіші will immediately shut-off and lock the Оттық of the өндірістік қазан. Even though, Оттық is fixed, it still needs to be reset manually

To prevent such extremely dangerous events and to lock Оттық of the өндірістік қазан safely, low level alarm limiter should be used. The limiter is used for monitoring a water minimum fill level in өндірістік бу қазандары. If the water level falls the below the minimum, the limiter should switch off the Оттық so that over heating can be prevented before injury to people or damage to installation. The Деңгей реттегіші is self checking 52 times every second. Thus, no need for testing button for the controller
