1 Correct installation (1) Power supply voltage: The voltage fluctuation should meet the national standard within 10%, otherwise some manufacturers' centrifuges will not operate normally. If the voltage fluctuates above this, it is recommended to use a voltage regulator to comply with this grid.
(2) The ground wire should be firmly: the wiring of the power supply of the room should meet the requirements. China is a three-phase four-wire system. The three-phase is the three-phase in industrial power. When three-phase electricity is used, the neutral line is separated from the ground line. More importantly, whether it is three-phase industrial power or not, the general single-phase power is good, and the ground line should be reliable to avoid leakage. The ground wire cannot be connected to the heating pipe or the water pipe.
(3) The ground should be flat and firm: for large centrifuges, the floor should be firm at the installation site to ensure the normal operation of the rotor of the centrifuge, without recessing, and the ground at the installation and fixing should be flat and firm.
(4) Find a good level: find a more accurate small level, open the lid of the centrifuge, find the level on the main shaft, and adjust the level of the adjusting bolts next to the four casters to find the level. Note that one of the feet cannot be lost.
2 When the design of the centrifuge is designed and manufactured, the imbalance of the machining error of the rotor has been remedy for the dynamic balance test. However, all centrifuges have their allowable unbalanced load. Centrifuge manufacturers compete with other manufacturers for the large unbalance limit allowed by the centrifuge, and try to give a larger value. At this larger value, the centrifuge can be operated, but the imbalance force generated at this time suddenly hits the bearing and the bracket at n times per minute, and the centrifuge is damaged. Therefore, users should try to find a good balance and centrifuge for those expensive centrifuges, which is good for the life of the centrifuge.
3 Clean the water in the centrifugal chamber. When the centrifuge is running, it uses refrigeration. Because of the moisture of the air, it is frosted in the centrifugal chamber. After the shutdown, it is frosted into water. Most foreign low-speed large-capacity centrifuges have no drainage holes, and the water in the centrifugal chamber is more and more accumulated. At this point, the user should remove the rotor and clean up the accumulated water. When reinstalling the rotor, be sure to install it to avoid accidents.
4 Aluminum alloy can not be corroded The rotor of the centrifuge is generally made of aluminum alloy. When it is corroded, the strength is reduced and it is easy to cause an accident. The aluminum alloy is susceptible to liquid corrosion. After cleaning, it is blown dry with a hair dryer, or inverted for a period of time to confirm that it can be used. Some blood stations imported centrifuges, and there should be 6 plastic trays in 6 aluminum cups. The plastic tray should be placed in a blood bag to avoid direct placement in the aluminum cup. Note the test tube for cracks. If the test tube (especially the test tube used repeatedly) has cracks, it must not be used. Otherwise, the test tube rupture will cause the rotor to lose its balance during rotation, which may cause a vicious accident such as broken shaft.
5 Broken shaft accident The rotor is not placed well, the sample is unbalanced, or the centrifuge is started when the amount is too large. Although modern imported centrifuges have unbalanced protection, that is, when the unbalance amount exceeds a certain limit, the power should be automatically cut off to stop the centrifuge. However, in the above case, it is already late, and a serious accident will occur. One of the malignant accidents is the broken shaft. Due to the sudden breaking of the shaft during high-speed rotation, the centrifugal rotor has no support, and the centrifugal machine is turned into a chaotic collision, which can make the centrifuge rotate the machine to a 270° angle. At this time, if there are people or equipment next to it, it will cause casualties and damage to the equipment.
Boysenberry Loquat Lycium Puree, the sweet and sour fruit and the slightly astringent taste of Lycium berry puree complement each other, care for your health, breathe freely, and bring you a fresh flavor.
The research and development personnel of Red Power went deep into the production area in the early stage, searched for several large loquat bases across the country, and finally selected China's "Hometown of Loquat" in Renshou County, Sichuan Province, which is also one of the National Geographical Indication products.
The unique climate and ecological advantages make Renshou loquat plump, delicate flesh, clear taste, and rich in cellulose, carotene, vitamins, organic acids, etc. However, due to the limitation of origin and picking time, the time to market for loquat is very short every year.
Loquat can not only be eaten directly, but more importantly, it can be used as a medicinal primer. "Compendium of Materia Medica" records: Loquat can "moisturize the five internal organs, nourish the heart and lungs." Especially for all kinds of coughs, or the common smokers' pharyngitis, it has a good relief effect. In addition, loquat is rich in vitamins, which can help improve the body's immunity, and then resist the invasion of foreign viruses, thus playing a role in preventing influenza. It is known as the "golden fruit" with the same medicine and food.
Boysenberry is a hybrid strawberry, belonging to the blackberry variety. It was chosen because it not only has a sweet and sour taste, but also has extremely high functionality. Boysenberry is called "super berry". It contains twice as much antioxidants as blueberries. It is a natural nutritional supplement that improves immunity. It is effective against lung damage caused by air quality problems, smoking or other external factors. Inflammation, has a good preventive and repairing effect, and gives natural support to troubled lungs. More importantly, Boysenberry has a positive effect on preventing lung tissue mutation and treating damaged lung tissue.
Plus Red Power`s main product: fresh goji berry puree.
The pursuit of good raw materials perfectly fits the concept of professional products, and also echoes the ingenuity flowing in the blood of Red Power.
Lycium barbarum puree helps improve immunity, loquat can reduce inflammation and oxidation in the respiratory system, boysenberry helps reduce the level of lung fibrosis, and the three synergistically bring you the most natural gift of this spring.
Boysenberry Loquat Lycium Puree is not only superior to the high-quality raw materials selected in the early stage, but also the production process is the inheritance and development of Red Power's non-concentrated reduction technology for many years.
Pure physical pressing, without any chemical additives in the whole process, to ensure product safety, hygiene, pollution-free, and natural nutrition is not destroyed.
Only when the juice content reaches 100% can it be called a juice, otherwise it can only be called a juice drink. Just because it is pure and natural, without adding any water, essence, preservatives, coloring, etc., it retains the original flavor to the greatest extent.
From the fresh fruit to the puree, every step is personally controlled, keeping the original taste and nutrients of the fresh fruit. Every step is interlocking, and every step cannot be missed. From this point of view, the entire production process is more like a science. Only by accurately mastering a "just right" measure can we make every product well.
The 28 processes are exquisite and exquisite step by step, finally creating the mellow but not astringent, sweet and sour, fresh and just right.
