The principle of RO water purification is also known as the principle of RO reverse osmosis. RO reverse osmosis is a method of filtering raw water (physical method) without adding any compounds to produce pure water that can be directly consumed by humans through internationally popular reverse osmosis and other methods. Water equipment (also called terminal water purification equipment). The municipal tap water whose water quality complies with the "Sanitary Standards for Drinking Water Quality" (2001) of the Ministry of Health of China is used as raw water. Filter, and then apply pressure to the pre-filtered water to pass through an RO (Reverse Osmosis) membrane with a pore size of one ten-thousandth of a micron, and finally pass through the silver-loaded activated carbon (also known as coconut shell) made of fruit shell (coconut shell). Small T33) Adjust the pH of the water (make the pure water taste sweet and mellow) to produce pure water.
The purified water produced by the RO reverse osmosis water purification mechanism is fresher, more hygienic and safer than bottled water. It has a wide range of uses: it can be drunk raw or boiled. The most prominent feature in this regard is the kettle or Electric thermos will no longer scale; pure water is used for cooking, which is more hygienic and more delicious; bathing with pure water can remove impurities on the skin, moisturize the skin, and have a natural beauty effect; it can be provided to humidifiers, The water needed for small appliances such as steam irons and beauty instruments will never show annoying scale; when used in conjunction with the ice maker, the ice cubes made are crystal clear and without any peculiar smell

Second, test the engine. During the commissioning process, pay attention to observe the oil pressure gauge and the oil temperature gauge, and whether the water temperature gauge is stable within the specified range. Listen carefully to the sound of the engine running and observe whether there is abnormal noise. If there is abnormal sound, stop it in time and troubleshoot it. The engine test run time is generally: cold grinding for 6 hours, hot grinding in the low speed, medium speed, high speed sequence, followed by 15 minutes, 10 minutes and 5 minutes.
3. Remember to check the condition of each component after one round of test drive. Check for loose fasteners, bushings, bearings with signs of heat, belts and chains that are loose and worn, heat out the engine oil sump, gearbox, lubricant in the reduction gear and hydraulic tank Hydraulic oil and thoroughly clean the filter at each part. After all the inspections, once again in the Tanaka for the test run harvesting, do not rush to open all the horsepower, after running for a while and then full of skill, everything can be put into formal harvest.
Fourth, check the separation, cutting, threshing, unloading and other working institutions commissioning. The sequence of operations in sequence should be small throttle, medium throttle, large throttle, first partial, and then fully carried out. Be sure to pay more attention to whether the operation of each part is normal, whether there is noise, whether the hydraulic components and monitoring instruments are moving freely, stable and reliable. Once the problem is found, stop the test immediately and continue testing. The time is usually: 3 hours for small throttle, 2 hours for medium throttle, and 1 hour for big throttle.
Daily maintenance is essential to ensure trouble-free operation of the machine for a long time.
First, the normal boot test machine. After the engine is running normally, the test runs from 1st to 2nd, and 3rd and then reversed. Check the steering mechanism and turn to the left and right respectively. Brake, interlocking mechanism, whether the clutch is sensitive and reliable, whether the clutch is completely separated, whether the shifting is light or not, whether the meter is running normally, if there is any abnormality, stop immediately and eliminate the fault. The time for trial rotation is generally mastered: reverse gear 10 minutes, 3 gear 20 minutes, 1 gear 30 minutes, 2 gear 30 minutes.
