Description

Technical Field

[0001] The utility model belongs to the technical field of reverse osmosis membranes, in particular to a reverse osmosis membrane component. Background Art

[0002] Reverse osmosis membranes are artificial semipermeable membranes with specific properties, modeled after biological semipermeable membranes. They are the core component of reverse osmosis technology. The principle of reverse osmosis technology is to separate substances from water under the influence of a pressure higher than the osmotic pressure of the solution, based on the fact that other substances cannot pass through the semipermeable membrane. The reverse osmosis membrane has a very small pore size, so it can effectively remove dissolved salts, colloids, microorganisms, and organic matter from water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process, and easy operation.

However, the installation is relatively cumbersome by threading the cover end to the outer tube, and it needs to be twisted a certain number of times to complete the installation. Moreover, when the size of the end cover and the outer tube is large, the twisting process will be more time-consuming and labor-intensive, and it is very easy to have a matching deviation, which requires repeated comparison and installation, thereby reducing the installation efficiency of the staff.
