The pre-start inspection of the reverse osmosis unit involves many aspects to ensure that the equipment can operate normally and safely. Here are some of the main checking steps:
1. Equipment integrity inspection: First, check the shape of the reverse osmosis equipment to determine whether it is damaged or contaminated, so as not to affect its normal operation. If the equipment is damaged or contaminated, it should be repaired or cleaned in time.
2. Filter element inspection: check the filter element used by the equipment to determine whether its performance is normal and whether it can operate normally. The condition of the filter element has an important impact on the operation of the reverse osmosis equipment, and if the filter element is not performing well, it should be replaced in time.
3. Installation status check: check the installation status of the equipment to ensure that the equipment can work normally, and ensure that the wiring and grounding of the equipment are safe and reliable. If there is a problem with the installation status, it should be adjusted or repaired in time.
4. Valve inspection: check the valves of the reverse osmosis equipment to ensure that they can work normally and ensure that they are safe and reliable. In particular, whether the raw water pressure regulator and the concentrated water pressure regulator are fully open, and whether the electric slow opening valve can be automatically opened and closed according to the program. If there is a problem with the valve, it should be adjusted or repaired in time.
5. Pipeline inspection: Before connecting the reverse osmosis to the pipeline, the pipeline should be purged and flushed, including the reverse osmosis feed jellyfish pipe. Note: Do not flush with the membrane element system. At the same time, check the suitability of the pipes for pressure and pH, as well as whether the pipes are connected correctly.
6. Instrument inspection: check whether the pressure gauge, flow meter, conductivity meter and other instruments of reverse osmosis are installed correctly and calibrated to ensure their accuracy and reliability. At the same time, check whether the alarm and safety valve settings are correct.
7. Drug injection amount inspection: reconfirm whether the injection amount of various drugs in the reverse osmosis system is appropriate to meet the operation requirements of the equipment.
8. Water supply system inspection: Before running the reverse osmosis equipment, it is also necessary to check the water supply system to ensure that the water quality meets the requirements. If the water quality does not meet the requirements, it may cause damage to the reverse osmosis equipment and affect the normal operation of the equipment.
In short, the inspection before the start of operation of the reverse osmosis plant involves many aspects, and it is necessary to comprehensively and meticulously inspect all aspects of the equipment to ensure that the equipment can operate normally and safely. At the same time, it is also necessary to pay attention to the daily maintenance and maintenance of the equipment to prolong the service life of the equipment and improve the operation efficiency of the equipment.
