[0021] Connection between raw water pipeline and concentrated water pipeline: When installing raw water inlet 15 and concentrated water inlet 14: keep them horizontal or vertical, align the positions of raw water inlet 15 and concentrated water inlet 14 with the positions of pipeline interfaces, connect the positions of raw water inlet 15 and concentrated water inlet 14 with the pipeline interfaces with flexible clamp joints, do not connect any pipeline to the shell rigidly, and the pipeline is an independent supporting structure. After confirming that the coaxiality deviation between raw water inlet 15 and concentrated water inlet 14 and between membrane shell 1 and pipeline is within the allowable tolerance range, tighten the binding bolts.

[0022] The side of the pressure plate 2 is abutted with three groups of blocks 4 that are equidistantly arranged in a circle around the central axis of the membrane shell 1. A group of hexagonal screws 7 is provided between the ends of two adjacent groups of blocks 4, which can effectively ensure the stability of component installation. The interior of the pressure head 3 is provided with two groups of first sealing rings 9 that abut against the surface of the end head 5, the interior of the pressure head 3 is provided with two groups of second sealing rings 10, and the outer ring of the pressure head 3 is provided with a third sealing ring 11 that abuts against the inner wall of the membrane shell 1 to ensure the sealing of the connection between the devices.

[0023] Install the end assembly: Before installing the end assembly, clean the inner surface of the membrane shell 1, the sealing ring groove of the end assembly and the sealing ring, and thoroughly remove the residue on the surface, install the third sealing ring 11 in the sealing groove of the pressure head 3, and evenly apply a small amount of glycerin to the third sealing ring 11, the corresponding sealing position of the membrane shell 1, the membrane sealing ring, and the surface of the central connecting pipe of the membrane. Hold the water purification port 16 and push it into the membrane shell 1 in the horizontal direction of the shell until the fixing groove of the block 4 is completely exposed. If it is difficult to push it forward by hand, it is recommended to use a wooden square or plastic stick to support the end cover, and use a rubber hammer to evenly knock on the outer surface of the end cover to reach the specified position. Install the block 4: Clean the fixing groove of the block 4, put the three-petal block 4 into the fixing groove in turn, and simultaneously screw the three hexagon socket screws 7 into the screw holes, and tighten the hexagon socket screws 7 by hand.

[0024] Connection of purified water outlet pipe: After the pipe is screwed into the purified water outlet 16, it is perpendicular to the purified water outlet 16. The force with which the pipe is screwed into the purified water outlet 16 is such that it cannot be twisted directly by hand. The pipe thread should match the thread of the purified water outlet 16 (for example, if the purified water outlet 16 is a 1 / 2 inch G external thread, the pipe thread should be a 1 / 2 inch G internal thread).

[0025] Open the membrane housing: turn off the pressure source and release the pressure completely. Before any maintenance and repair, please make sure that the entire system is completely closed and the pressure is completely released. Separate the water purification outlet 16 pipeline: carefully separate the pipeline connected to the membrane housing, use the hexagonal wrench to remove the hexagonal screw 7 that limits the stopper 4, use a screwdriver to pry the stopper 4 out of the stopper 4 fixing groove, and remove the end assembly.

[0026] The bottom of the membrane shell 1 is provided with multiple groups of saddles 12 for providing support therefor, and the top of the saddle 12 is connected with a hoop 13 for binding the membrane shell 1. The membrane shell 1 must be kept level when it is placed on the bracket, and the shell should not be bumped by the bracket, and must be in full contact with the saddle 12. The saddle 12 bears the entire weight of the shell, ensuring that the shell is in full contact with all saddles 12, and then the membrane shell 1 is bound with the hoop 13.

[0027] The membrane shell 1 is made of epoxy fiberglass, and the end components are composed of a pressure plate 2, a pressure head 3, a block 4, an end head 5, a plug 6, a retaining spring 8 and other components. The honeycomb pressure plate 3 is made of high-density aluminum alloy to ensure the safety of the membrane shell 1 under high-pressure operation inside the membrane shell 1. The pressure head 3 and the like are injection molded using high-strength engineering plastics, standardized production, stable dimensions, and suitable for industrial mass production. The sealing rings are made of environmentally friendly EPDM material to ensure the cleanliness of water and are suitable for sealing high-pressure containers. The external fixing hoop 13 firmly fixes the membrane shell 1 on the saddle 12 during transportation of the membrane shell 1, thereby ensuring the stability of the membrane shell 1 during transportation and preventing the membrane shell 1 from being damaged, which can greatly save time and labor intensity during installation and use.
