Tyre inflation should be standardized
1, inflate should pay attention to safety. Always check the air pressure with a barometer to avoid over-inflating and bursting the tires. Replacement of new contents for tire filling Nitrogen = comfort + fuel-saving to the owner of the trick: buy "low-carbon" tires 2. After stopping driving, wait for the tire to cool before re-inflating, as the temperature of the tire when the vehicle is moving will increase, affecting the pressure .
3, check the valve. If the valve stem and the valve core do not match with each other, there are protruding recesses and other defects, and it is inconvenient to inflate and measure the air pressure.
4, inflate should pay attention to clean. The filled air must not contain moisture and oil to prevent deterioration of the inner tube rubber.
5, when the inflation should not exceed the standard air pressure after the release of deflation, can not be too long after the out inflated and over inflated, if more than the standard will lead to excessive expansion of the cord, causing its strength to reduce impact The life of the tire.
6, before filling the valve should wipe the dust on the mouth, do not loosen the valve core, after the completion of the application of soap bubble water (or saliva) painted on the valve, check for leaks (if the leak will produce small bubbles) , And valve caps are tightly fitted to prevent sediment from entering the interior of the valve.
7. When the radial tire is inflated, due to structural reasons, the amount of sinking and grounding is large, and it is often mistaken for insufficient inflation and overinflation; or vice versa, because the amount of sinking and grounding area is larger. In the absence of air pressure, it is also mistaken for sufficient. Apply a standard barometer to measure. The radial pressure of the radial tires should be 0.5-1.5kg/cm2 higher than that of ordinary tires.
8. The barometer used in the car or the barometer used between the tires should be calibrated regularly to ensure accurate pressure check.
Near the Mid Autumn Festival, various moon cake iron boxes with exquisite patterns can be seen everywhere. The moon cake iron boxes on the market are getting better and better each year. Of course, a good Iron Box is not measured by its beautiful appearance, but by its good quality. Good quality. We can use it again after using it. Then, how to judge whether the quality of the iron box has reached the standard?
When we first see the iron box, we will have an objective judgment on the box. The first thing we see is the surface of the iron box. The information reflected on the box surface, such as patterns, printing, barcodes, models and specifications, is not randomly placed. It has certain rules. The randomly printed iron box is already unqualified on the surface. Again, check the box surface for scratches, and the printed surface shall not be greater than 0.3mm * 20mm. On the front side, the pattern of the product surface is placed directly in front of and below the sunlight. In addition to the main viewing surface of the box, you can also see the inner surface, side, bottom, etc.
The above are the tips that can manufacturers share with you on how to judge whether boxes are standard. Have you learned?
