[0002] The main purpose of reverse osmosis membrane detection sampling tube is to extend into the membrane for sampling, and the water sample is flowed into the sampling bottle, and then the handheld conductivity detector is used to detect the conductivity of the collected water in the sampling bottle. This tool is convenient and fast to operate, and by measuring the water conductivity of a single membrane, the performance and integrity of the reverse osmosis membrane can be evaluated.

[0003] The material, length, assembly structure and other parameters of the sampling tube are different, and need to be customized according to the actual needs on site to meet various special operation requirements. Generally, each 8-inch reverse osmosis membrane container installs 6-8 membranes, and the length is 6-8 meters. When sampling and detecting all membranes in the reverse osmosis membrane container, if the plant space is large, a 6-8 meter sampling tube can be directly used for detection. However, in order to save floor space, the distance between the reverse osmosis membrane water production side and the plant inner wall is generally 2-3 meters, and the operation method of using a 6-8 meter single sampling tube is difficult to implement. The main reason is that there is a certain pressure on the water production side, and when the flexibility of the sampling tube meets the requirements, the rigidity is not enough, and the sampling tube is easily washed out by the water flow; when the rigidity of the sampling tube meets the requirements, the flexibility is not enough, and the bending degree is limited, so the sampling tube is difficult to stretch into place. The traditional sampling tube is not convenient to operate in narrow space and different insertion lengths, and the flexibility and rigidity are difficult to balance, which increases the labor and reduces the work efficiency.
