Technical Field

[0001] The utility model relates to the technical field of energy-saving water pumps, in particular to a water pipe flange sealing device for an energy-saving water pump. Background Technique

[0002] An energy-saving water pump is a water pump device that can effectively reduce energy consumption during operation. Usually, advanced hydraulic design and efficient motor technology are adopted. Its working principle is similar to that of a traditional water pump. The impeller is driven by a motor to rotate, converting mechanical energy into the kinetic energy and pressure energy of the liquid, thereby realizing the transportation of the liquid.

[0003] Currently, flanges are usually fixed by bolts. However, bolt fixing is not convenient for disassembly and assembly. When installing flanges, multiple bolts need to be tightened one by one. This process usually requires tools such as wrenches, and the operation is relatively cumbersome, consuming time and labor. Especially in large pipeline systems, the number of bolts is numerous, and the installation work is more arduous. And when it is necessary to repair or replace components of the pipeline system, removing bolts can also be a challenge. Bolts may rust, get stuck due to long-term use, or deform due to excessive force during tightening, making disassembly difficult. This may require the use of special tools or destructive methods to remove the bolts, increasing the maintenance cost and time. Content of the Utility Model
