Now water purifiers have begun to be used frequently in various regions, and the use of drinking fountains is slowly being replaced by water purifiers, which can be seen in some public places and in every family. There are more and more domestic water purifier products, so here we briefly talk about what kind of water purifiers are good and how to use domestic water purifiers. 
What kind of water purifier home
1. A household water purifier is a treatment device that purifies water. Using it can effectively remove chlorine from the water. Activated carbon can remove some organic substances from the water. The approximate structure includes several types of coarse filter, activated carbon adsorption, ion exchange resin, hollow fiber and reverse osmosis membrane. Good water purifier-treated water is clean and free of bacteria, which can improve the taste. Nowadays people's demands for health are getting higher and higher, so household water purifiers are more widely used.
2, home water purifier in the brand, style, price, design, there are many differences, then this will be better to use is the multi-stage filter water purifier and reverse osmosis water machine. The treated water can be directly consumed without boiling, and there is also a gold filter water purifier that purifies the water while supplementing the body's trace elements. The higher cost-effective water purifiers on the market now require comfortable multi-stage filter water purifiers. They can be accepted by the working class and are used in more families. 
3. When we use household water purifiers, we may also have a situation where the tap water is stopped. After this period of water stoppage, we will use it again when we need to flush the sewage and then use the clean water. Device. Because the aging of the main pipeline to drink galvanized water will bring a lot of rust, sediment, will lead to very poor water quality.
How to use home water purifier
1. When the domestic water purifier is in use, if there are some failures, then the water inlet valve of the tap water must be closed immediately, and the water inlet channel of the water purifier is directly cut off. Then call the installer, the water purifier is a small filter device, the structure has a certain degree of complexity, non-professionals do not disassemble. 
2, there are some home water purifiers in line with national drinking water standards, it is possible to drink boiled water directly for a long time, but it is best not to drink cold water, because in the case of long-term drinking water. Suddenly drinking cold water can make the stomach not fit, which can lead to diarrhea. This is not because the water purifier is not up to standard. After the household water purifier is installed, the water valve should be closed for a long time without using it to prevent the tap water from generating water hammer under the condition of water passing. Instantaneous pressure will cause damage to the water purifier.
3. If we are installing a household water purifier in a cold northern region, we must not install it outdoors. If there is water accumulation in the water purifier due to the weather, it will freeze and then expand. Causes the water purifier filter to rupture, in severe cases, the shell may also be frozen and cracked. As a public drinking water facility, the installation place of the Connaught water vending machine is generally outdoor, so the automatic water vending machine is equipped with an insulation system and a temperature control system.

Thin wall ball bearings are simple in structure and easy to use. Mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of Angular Contact Ball Bearing and can bear combined radial and axial load.
When the speed is high and thrust ball bearings are not suitable, thin wall ball bearings can also be used to bear pure axial loads. Compared with other types of bearings of the same size, this type of bearing has a small friction coefficient and a high limit speed. But it is not impact resistant and not suitable for heavy loads.
Thin wall ball bearings have a bearing inner diameter and outer diameter ratio less than a specified value. The ratio of bearing outer diameter to bearing inner diameter is 1.25 or less. It is called thin wall ball bearings, which means that the outer diameter-inner diameter value of the bearing is very small and the bearing wall is very thin.
The precision required by thin wall ball bearings is very high, because the wall is very thin, so the weight it can carry is also very low, and the impact resistance is very poor, so this must be selected according to the use environment!
Characteristics
The specific use of thin wall ball bearings:
Model airplanes, remote control cars, machine tools, motors, water pumps, agricultural machinery, textile machinery, laser printers, instruments, measuring instruments, electronic accessories, motors, motors, etc.
