[0002] Reverse osmosis equipment is a water treatment system that uses the principle of semi-permeable membranes. It is widely used in fields such as seawater desalination, wastewater treatment, and drinking water purification. Its working principle is to force water molecules through the semi-permeable membrane by applying pressure, preventing the passage of impurities, salts, and other pollutants, thereby obtaining high-purity water. Reverse osmosis equipment is characterized by high efficiency, energy saving, and environmental protection. It can effectively remove dissolved salts, heavy metals, and organic matter in water, ensuring water quality safety and sustainable use.

[0003] The high-pressure pump is an important component in reverse osmosis equipment. It provides sufficient pressure to overcome the osmotic resistance of the osmotic membrane and force the water molecules in the incoming water through the semi-permeable membrane. In this way, the high-pressure pump can effectively separate the dissolved salts and other pollutants in the water, thereby achieving water purification and desalination. The high-pressure pump is generally fixed to the equipment by bolts to ensure stability during operation.

[0004] However, since the high-pressure pump is fixed by bolts, it makes the maintenance and replacement of the pump more difficult. Multiple parts need to be disassembled for inspection and repair. The disassembly process is relatively cumbersome, and the bolts are prone to moisture and rust after long-term use, which makes it inconvenient to disassemble, increasing maintenance costs and time, resulting in reduced maintenance efficiency. For this reason, those skilled in the art have proposed a two-stage reverse osmosis device to solve the above problems. Utility Model Content
