Advantages and Disadvantages of Water Filter Vacuum Cleaner? Precautions for Water Filter Vacuum Cleaner?
Water filter vacuum cleaners are very important for the whole room. Many owners are very cautious when selecting water filter vacuum cleaners, but because there are too many brands of water filter vacuum cleaners on the market, plus merchants' promotions. Constantly, this has led many homeowners to buy water filter vacuum cleaners or to feel that the water filter vacuum cleaner is not good after using for a period of time. In order to solve this problem, I will follow the advantages and disadvantages of water filter vacuum cleaner and water filtration. Vacuum cleaner precautions These two aspects are recommended to recommend water filter vacuum cleaners. What are the advantages and disadvantages of water filter vacuum cleaners? The water filter vacuum cleaner adopts water filtration technology. Now this technology has been fully recognized in the market. The water medium is used as the filter medium, so that the vacuum cleaner can absorb the wet garbage. And in response to various kinds of garbage, the water filter vacuum cleaner can be well cleaned, and the current water filter vacuum cleaner can absorb liquid objects such as paste objects such as rice slag sauce, water drinks, and slippery adhering objects such as broken eggs. Sharp objects such as broken glass nails. 2, water filter vacuum cleaner has a big advantage is that there is no dust flying when used, the traditional vacuum cleaner will use the dust, the dust will overflow with the high-speed filter channel, and in order to prevent dust from flying when it reaches the dust, It is very small, and the advantage of the water filter vacuum cleaner is that it can wet dust and garbage with water, dissolve and lock the dust, and avoid dust rising when it reaches the dust. 3, water filter vacuum cleaner is better than the traditional vacuum cleaner, and the water filtration technology is currently the most efficient and powerful filtration method. This type of vacuum cleaner will not cause secondary pollution of the air when it is used, and it will prevent the family from affecting the health of the respiratory tract due to dust. And with the medical grade HEPA and other effective filter materials, can be combined into a perfect purification filtration system, and the water filter cleaning is also very convenient, after the wet garbage everywhere, the simple cleaning of the water tank can be . Water filter vacuum cleaner precautions? 1, I have a large amount of belly, but drink less water: In addition to adding 250ml of water as a filter medium, I can also absorb 300ml of liquid, which can fully meet the needs of general household cleaning. But still remind the parents, don't let me drink too much water, otherwise the liquid will splash out, although it will not damage the machine, but it will affect the pro-cleaning task~ must pay attention to it~ 2, red and yellow have marked, pull the wire please note: In order to give the pro-protection machine, Delmar vacuum cleaner has made two red and yellow marks on the power line. Pull to the yellow mark to remind you to slow down the cable speed! A red mark appears, reminding you to stop pulling the wire, otherwise the excessive force may damage the vacuum cleaner's automatic shrink device. 3, the power can be adjusted, the small file is more economical: when doing ordinary housework cleaning, just turn the vacuum cleaner power to one or two files to get the cleaning task! It is easier, quieter and more economical~ 4, maintenance tips, hoses to be cleaned: after each cleaning, parents must remember to clean the hose (remove the hose to one of the head facing the faucet, directly rinse ~) because all vacuum cleaners vacuum After that, more or less residue remains in the hose, so the hose must be cleaned regularly. Pro, seeing the bacteria is not terrible, the invisible bacteria are terrible! Nowadays, there are many water filtration vacuum cleaners on the market. It is still necessary for consumers to judge which one to choose. However, I hope that everyone can consider the above mentioned brands when making purchasing judgments. Of course, I hope everyone can finally buy them. Self-satisfied laminate flooring.

Product Description
SPD Surge Protective Device,Lightning Surge Protector
Surge Protection Device (SPD)
It is a device used to limiting instant surge voltage and discharge surge current, it at least including a non-linear component.
Surge protective Device Model Selection
With the impact of international information flow, the rapid development of microelectronic science and technology, communication, computer and automatic control technology, make the building start to go for high quality, high functional area, formed a new building style-intelligent building. As inside the intelligent building there are lot of information system, <<Building lightning protection design norm>> GB50057-94(2002 vision)(hereafter brief as <<lightning protection norm>>) put forward the relative requirement to install the surge protective device, to ensure the information system safely and stable running.
SPD essentially is a equipotential connection material, its model selection is according to the different lightning protection area, different lightning electromagnetic pulse critical and different equipotential connection position, decide which kind of SPD used in the area, to achieve the equipotential connection with the common earth electrode. Our statement will based on SPD's maximum discharge current Imax, continuous operating voltage Uc, protection voltage Up, alarm mode etc.
As per << Lightning Protection Norm>> item 6.4.4 stipulation "SPD must can withstand the expected lightning current flow and should confirm to the additional two requirements: the maximum clamp voltage during surge across, capable to extinguish the power frequency follow-on current after lightning current across." That is the value of SPD's max. clamp voltage add its induction voltage of two ends should be same with the system's basic insulation level and the equipment allowed max. surge voltage.
SPD for Power Supply System Series Selection Guide
The installation of SPD at each lightning protection zone, according to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category, its insulation withstand impulse voltage level can determine the selection of SPD. According to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category as signal level, loading level, distribution and control level, power supply level. Its insulation withstand impulse voltage level are:1500V,2500V,4000V,6000V. As per to the protected equipment installation position different and the different lightning current of different lightning protection zone, to determine the installation position of SPD for power supply and the break-over capacity.
The installation distance between each level SPD should not more than 10m, the distance between SPD and protected equipment should as short as possible, not more than 10m. If due to limitation of installation position, can't guarantee the installation distance, then need to install decoupling component between each level SPD, make the after class SPD can be protected by the prior class SPD. In the low voltage power supply system, connecting an inductor can achieve the decoupling purpose.
SPD for power supply system specification selection principle
Max. continuous operating voltage: bigger than protected equipment, the system's max. continuous operating voltage.
TT System: Uc≥1.55Uo (Uo is low voltage system to null line voltage)
TN System: Uc≥1.15Uo
IT System: Uc≥1.15Uo(Uo is low voltage system to line voltage)
Voltage Protection Level: less than the insulation withstand impulse voltage of protected equipment
Rated discharge current: determined as per to the lightning situation of the position installed and lightning protection zone.
