The shell, also called a membrane pressure vessel, is a supporting product for reverse osmosis, sodium filtration, ultrafiltration and other devices. The shell is made of stainless steel tubes or wire-wound fiberglass, and the membrane shell is polished inside and outside.
Two main technical characteristics
Pressure resistance
Water inlet from both ends
Standard structure of spare parts, easy and quick disassembly
Durable sealing Pressure test
The structure of both ends is clamp type, card type and inner spring type.
It depends on the requirements of the designer. The arrangement of the membrane and the requirements of the sections are different. According to the different angles of the inlet and outlet, it is divided into three types: degree, degree, and degree. Simply speaking from the pressure resistance theory, side water inlet is better. Some, but increases the chance of water leakage from the pressure vessel.
The water flow rate and pressure of the membrane are much larger than those of the inch membrane. If two openings are opened on the membrane housing port, the pressure resistance of the end face will be reduced, and it will also add a lot of trouble to the installation
. The main problem is the flow rate of the concentrated water. Because the maximum water recovery rate of a single membrane element is designed to be The pressure drop is much larger, so the number of series connections cannot be too many. The specific number of series connections depends on the water quality and design parameters. Secondly, the selection of high-pressure pumps must also be considered.
