Description

Technical Field

[0001] This utility model relates to the field of urban direct drinking water delivery technology, specifically to an urban direct drinking water deep purification pump device. Background Technology

[0002] The water pump unit uses a motor to drive an impeller to rotate at high speed, creating negative pressure within the pump chamber. This draws in pre-treated raw water, and the impeller's high-speed rotation then imparts strong kinetic energy to the water flow, propelling it at high velocity to subsequent deep purification equipment, such as reverse osmosis and ultrafiltration membrane systems. Throughout this process, the pump provides stable water pressure and flow rate, ensuring the raw water undergoes continuous and efficient deep purification. The urban drinking water deep purification pump provides power to the entire deep purification system, guaranteeing the continuity and efficiency of the purification process. It plays a crucial role in improving the quality of urban drinking water and ensuring residents have safe and convenient access to drinking water.

[0003] For example, a liquid conveying water pump with application number CN202321637283.1 includes a pump body and a cooperating motor. The pump body is provided with an inlet pipe and an outlet pipe, both with connecting flanges at their ends. A sealing gasket is provided on the outside of the connecting flange, and sealing sections are provided on both sides of the sealing gasket. A connecting section is provided on the inlet pipe, and a sampling tube is provided on the side wall of the connecting section. An opening and closing structure is provided on the connecting section in conjunction with the sampling tube. An anti-backflow part is provided on the outlet pipe, and an anti-backflow plug is provided inside the anti-backflow part in conjunction with the outlet pipe. The backflow prevention plug is equipped with an elastic compression structure, and there is a flow gap between the side of the backflow prevention plug and the inner wall of the backflow prevention part. This utility model facilitates sampling during liquid transportation and can prevent backflow during liquid transportation. At the same time, it has good sealing performance when connected to external pipelines to prevent leakage during transportation. However, the pump body of this water pump device is prone to corrosion, has high energy consumption, and is prone to aging of components due to overheating. It also has large vibration peaks during start-up and shutdown, is prone to loosening of the seal with the pipeline, has high energy consumption for stable operation, and is difficult to adapt to the frequent start-up and shutdown conditions of direct drinking water systems.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a deep purification pump device for urban direct drinking water. Utility Model Content
