The constant-pressure water replenishment vacuum degassing unit is a device used in heating and cooling systems. Its main working principles include: vacuum degassing: first, the air in the water-replenishing system is extracted to form a vacuum state to avoid the air from causing adverse effects such as air blockage and corrosion on the system; constant-pressure water replenishment: under the vacuum state, the water pump is started to add the pre-prepared water into the system through the water replenishment pipe. At this time, since the system is in a vacuum state, the water can quickly enter the system and all the air in the system can be discharged; automatic control: when the water level in the system reaches a certain height, the unit will automatically stop replenishing water to avoid The water level in the system is too high, causing a safety hazard. When the water level in the system drops, the unit will automatically detect and perform water replenishment operations; Filtration treatment: During the water replenishment process, the unit is also equipped with a filtering device to filter out impurities and particulate matter in the water to ensure the purity of the water replenished into the system to ensure the normal operation of the system, including a water replenishment pipe 101, a filter assembly is provided at the end of the water replenishment pipe 101, and the filter assembly includes a water inlet Y-tube 200, a sealed bearing 203 is fixedly installed on the inner side of the water inlet Y-tube 200, a filter seat 204 is rotatably installed on the sealed bearing 203, a filter screen 210 is installed on the inner side of the filter seat 204, and a filter seat 204 is provided with a surface having a filter. Filter outlet 205, the water flow entering the filter screen 210 is discharged through the filter outlet 205, one end of the filter seat 204 is fixedly installed with a driven bevel gear 207, one side of the water inlet Y-shaped tube 200 is provided with an integrated motor seat 202, a filter motor 201 is fixedly installed on the motor seat 202, one end of the filter motor 201 is located on the inner side of the water inlet Y-shaped tube 200 and is installed with a driving shaft 208, a driving bevel gear 209 is fixedly installed on the driving shaft 208, and the filter assembly is used to filter scale in the water flow passing through the filter screen 210. When the unit in the application is used for water replenishment operation, the water inlet pipe can be of the same Y-shaped structure, aligned with the water inlet Y-shaped tube 200 After connection, when water flows in, the filter motor 201 works to drive the active shaft 208 and the active bevel gear 209 to rotate.
