Description

Technical Field

[0001] The utility model belongs to the technical field of water supply equipment, and specifically relates to a constant pressure secondary water supply equipment. Background Art

[0002] Constant pressure secondary water supply equipment is a constant pressure water pump system based on variable frequency speed regulation technology. This system intelligently controls the running speed of the water pump to maintain a constant water pressure set in the system, thereby meeting different water consumption and pressure requirements.

[0003] At present, constant pressure secondary water supply equipment usually has an air pressure tank to stabilize water pressure fluctuations, reduce the frequency of water pump start-stop and the impact of water hammer on water supply equipment. However, when the air pressure tank is protecting the constant pressure secondary water supply equipment, it will be affected by water hammer and may shake slightly, which will cause the tightness of the connection between the air pressure tank and the water pipe. At the same time, the water hammer phenomenon generally occurs inside the pipeline, so the force generated by the water hammer will be transmitted to the equipment through the pipeline. When the air pressure tank is used to protect the equipment, it cannot effectively protect the water pipe. The water pipe may vibrate when it is subjected to the force of water hammer, which may cause damage to the connection between the water pipe and the external pipe, which may affect the water supply effect of the equipment.

[0004] In order to solve the above problems, this application proposes a constant pressure secondary water supply equipment. Utility Model Content
