Variable-frequency non-negative-pressure secondary water supply equipment
The invention relates to the technical field of water supply equipment, and particularly discloses variable-frequency non-negative-pressure secondary water supply equipment. Comprising a base, a non-negative-pressure water tank, a control cabinet, a water inlet pipe, a water supply pipe and a variable-frequency water pump, the end of the water inlet pipe is connected with a water inlet filtering device, the water inlet filtering device comprises a box body, one side face of the box body is connected with a municipal water connecting pipe, and the end, extending into the box body, of the municipal water connecting pipe is connected with a telescopic pipe; a driving assembly for achieving left-right movement of the sleeve is arranged in the box body, a pipe inserting head moving up and down is attached to the interior of the sleeve, the lower end of the pipe inserting head is open, the upper end of the pipe inserting head is sealed, and a water inlet hole aligned with the telescopic pipe is formed in the side face of the pipe inserting head. According to the invention, long-term pollution of water quality caused by residual impurities in municipal water in the non-negative pressure water tank can be reduced, the process of automatically replacing the filter cartridge on line is realized, manual replacement by an operator is not needed, interruption of water supply to a user is not influenced, and the use effect is very excellent.
本发明涉及供水设备技术领域，具体公开了一种变频无负压的二次供水设备；包括底座、无负压水罐、控制柜、进水管、送水管和变频水泵，进水管的端部连接有进水过滤装置，进水过滤装置包括箱体，箱体的一侧面连接有市政水接管，市政水接管伸入箱体的端部连接有伸缩管，伸缩管的端部连接有套筒，箱体中设置有实现套筒左右移动的驱动组件，套筒中贴合有上下移动的插管头，插管头的下端开口、上端密封设置，且插管头的侧面开设有与伸缩管对齐设置的进水孔；本发明能够减少市政水中杂质残留在无负压水罐中对水质造成的长期污染，而且实现了自动在线更换过滤筒的过程，无需作业人员手动更换，不会影响造成对用户供水的中断，使用效果十分优异。
