Knowledge Base

Q

‌&nbsp; Constant pressure water replenishment vacuum degassing unit; The main functions of the unit include the following aspects:<&order>voltage stabilization and water replenishment: The unit can accurately control the system pressure, ensuring that the system operates within the designed working pressure range. When the system pressure is lower than the set value, the unit will automatically activate the water replenishment function, injecting water into the system through the replenishment pump to restore the system pressure.

Q

This article systematically introduces the working principle and selection points of the vacuum degassing constant pressure water replenishment unit, analyzes the causes of common problems such as water hammer and pipe burst during operation, and provides practical suggestions for equipment installation, commissioning, and daily maintenance to help users optimize the performance of HVAC systems.

Q

The constant pressure water replenishment vacuum degassing unit is a mechanical equipment that integrates the functions of constant pressure, water replenishment, expansion, and vacuum degassing. It is mainly used in closed circulating water systems (such as central heating, central air conditioning, industrial cooling, etc.). Through the pressure stabilization of the pressure tank, vacuum pump degassing, water pump replenishment, and intelligent control, the system pressure is stabilized, the water volume is automatically compensated, and the gas is efficiently discharged, ensuring
