[0002] The main purpose of the reverse osmosis membrane detection sampling pipe is to extend into the membrane to take samples, 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. The tool is convenient and fast to operate, and the performance and integrity of the reverse osmosis membrane can be evaluated by measuring the water conductivity of a single membrane.
[0003] The material, length, assembly structure and other parameters of the sampling pipe are different, and need to be customized according to the actual needs on site to meet various special operation requirements. Generally, the number of membranes installed in each 8-inch reverse osmosis membrane container is 6-8, and the length is 6-8 meters. When sampling and detecting all the membranes in the reverse osmosis membrane container, if the plant space is large, a 6-8 meter sampling pipe can be directly used for detection. However, in order to save the floor area, 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 pipe is difficult to implement. The main reason is that there is a certain pressure on the water production side, when the flexibility of the sampling pipe meets the requirements, the rigidity is not enough, and the sampling pipe is easy to be washed out by the water flow; when the rigidity of the sampling pipe meets the requirements, the flexibility is not enough, and the bending degree is limited, so the sampling pipe is difficult to stretch into place.
