纯水机故障检测（Water machine fault detection） First, the machine abnormal sound: Pure water machine using silent pump, abnormal sound is because the pump for a long time, there is wear (often in the abnormal replacement of pretreatment filter products, users), the solution is to change the pump head or change the pump. Two, leakage: Fastening or filter bottle can be 1. shell shell or flask Water Leakage position, after fastening effect to replace the O ring; 2., common joints leaking again, tape or replace the joint, nut can be; 3. quick joint leakage, cut a section of water pipe after re * * *, still can not solve the replacement of the corresponding joints; 4., the pump head leakage fastening pump head screw, can not solve the need to replace the pump pad or directly change the pump. Three, water quality failed: Check the main RO film and shell: check at the end of the membrane **RO membrane position is too loose or is simply not inserted into the membrane, membrane is too loose can in the film O ring position wrapped with raw material and then coated with Vaseline reload, inserted directly into the membrane membrane replacement. In addition to the above situation, water quality does not meet the need to directly replace the RO membrane Four, no water: divided into water system failure and circuit system failure of two kinds Water system failure 1. check check valve working condition is pure water reflux; 2. check whether the raw water pressure is above 0.1MPA; 3. check the RO membrane pure water outlet flow is normal; 4. check whether the pressure tank is out of pressure and whether there is water in the bucket; 5. check whether the inlet valve is in open condition; 6. check whether the outlet pressure of booster pump is above 0.5MPA; 7. check whether the activated carbon is normal. 8. check the pre three stage pretreatment filter for obstruction; 9., check whether the plug connector tube blocked. Circuit system fault 1) check the computer version cable whether there is
