Description

Technical Field

[0001] The utility model specifically relates to the technical field of water pressure detection, in particular to a water pressure detection device for a reverse osmosis membrane. Background Art

[0002] Reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane. It is the core component of reverse osmosis technology. The principle of reverse osmosis technology is to separate these substances and water under the action of higher osmotic pressure than the solution, based on the fact that other substances cannot pass through the semipermeable membrane. The pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation.

[0003] When the reverse osmosis membrane is in use, it is necessary to detect and compare the water pressure entering the reverse osmosis membrane and flowing out of the reverse osmosis membrane. When the outflowing water pressure is less than the entering water pressure, the reverse osmosis membrane is damaged. The traditional detection method is to cut the water pipes at both ends of the reverse osmosis membrane and install a water pressure gauge for detection. When the length of the reverse osmosis membrane is different, it is more troublesome to use and install. For this reason, we provide a water pressure detection device for the reverse osmosis membrane. The sliding rod moves on the guide plate to adjust the position of the water pressure detection components on both sides, which is convenient for connecting reverse osmosis membranes of different lengths and performing water pressure detection. It is more convenient to use and effectively compensates for the above problems. Utility Model Content
