Question 2: What does the dynamic balance of automobile tires mean? As long as it is round, one position is light or the other position is heavy, it will be unstable to turn. . The dynamic balance of automobile tires is to adjust the weight of each position to the same. This will make the car drive more stably.
Question 3: How qualified is the dynamic balance of automobile tires? The standard is 00: 00 according to the size of your car tires and chassis, but some tires are difficult to meet this standard, so the size equal to 5G to 10G will not affect the normal use.
Question 4: How much does it cost to do a car tire dynamic balance? 4S stores basically have 20 wheels. Generally, just make the first two wheels. If you think this is better, do all four wheels.
Outside the tire shop, there is usually a wheel of 10 yuan.
One more thing, it is not the best to do dynamic balance alone. Four-wheel positioning should be done regularly, almost every 20,000 kilometers, and the price is around 300-400 yuan.
Question 5: What does the dynamic balance of automobile tires mean? Acid-base and daily chemical acid-base products cover a wide range. Many articles used in daily life, such as plastic products, rubber products, synthetic fiber products, soap, detergent, cosmetics, essence, stationery, etc., are all chemical acid-base products with a wide variety. Talcum powder talcum powder is mainly used to smooth skin and absorb sweat after bathing, and is a sanitary product suitable for men, women and children. The main component of talcum powder is talcum powder, and some calcium carbonate, magnesium carbonate, zinc oxide, kaolin, zinc stearate, magnesium stearate and a small amount of boric acid are used for sterilization and disinfection. In order to give people a cool feeling, a small amount of menthol should be added to the formula group. Bleach Bleach can remove dirt that can't be washed by ordinary methods. Chlorine-containing bleaching agents such as sodium hypochlorite have a strong bleaching effect, but because of its chlorine smell, it is easy to decompose during storage and can destroy fabrics and dyes, so sodium borate or sodium perborate without chlorine is generally used as bleaching agents. Sodium perborate is prepared by the reaction of borax, sodium hydroxide and hydrogen peroxide: na2b4o72nnaoh → 4nabo2h2o → nabo2h2o → nabo3? When the temperature exceeds 50℃, 4H2O sodium perborate will decompose and release hydrogen peroxide again, thus playing a role in bleaching. The disadvantage of sodium perborate is that it has enough solubility in aqueous solution above 50℃, but its solubility is very low at room temperature. Therefore, sodium perborate is only suitable for household detergent formula with hot water system, and is generally used in so-called warm washing areas such as Europe and America. In areas where cold water is used to wash clothes (cold washing area), such as China, Japan and Southeast Asia, sodium percarbonate is used as bleaching agent. It not only has good solubility at room temperature, but also releases hydrogen peroxide at a lower temperature. Its disadvantage is that its decomposition temperature is low, so its storage stability at room temperature is not good enough. Sodium percarbonate is prepared by the reaction of sodium carbonate with hydrogen peroxide. Sterilization and Disinfectant Disinfectants are drugs that prevent or kill microorganisms, while disinfectants are drugs that kill pathogenic bacteria or microorganisms. Usually it is toxic in itself, so it is usually used for external use. Among the commonly used fungicides, halogen, sodium hypochlorite, hydrogen peroxide and potassium permanganate are all oxidants, and their strong oxidation can destroy cells and of course harm human cells, so they are often used for disinfection and sterilization of inanimate objects. The earliest way to curl hair with perming agent is to heat and curl it, so it is called perm. With the development of cosmetics production technology, hair can be curled without heating and perming, that is, cold perming. Hair is composed of water-soluble keratin, which contains cystine. Cystine contains disulfide bonds to keep hair hard. Reducing chemicals (curling agents) can open this disulfide bond, and then the hair will become very soft and can be set at will. After styling, it will be oxidized by oxidizing chemical reagents (styling agents), the broken disulfide bonds will be connected, and the original rigidity, toughness and styling of the hair will be restored. Usually the curling agent used for heating is called perming agent, and another important ingredient is sulfite. In addition, a certain amount of alkali, such as potassium carbonate, borax, sodium carbonate or ammonia water, is added to maintain proper alkalinity. Cold perm agent, also called cold perm agent, is mainly composed of mercapto (C-SH) acetic acid and its derivatives, and other components are basically the same as those of perm agent. It should be noted that the pH value should be kept between 9.0 and 9.5 to achieve good results. After the treatment of curling agent, it is necessary to fix the hairstyle with styling agent, and also play a role in removing the residual curling agent. In the process of curling hair, the curling agent plays a reducing role and the styling agent plays an oxidizing role. The setting agent usually uses 3% hydrogen peroxide. Chemistry is a science that studies the nature, composition, structure, change and application of matter. Since the emergence of human beings, the exploration of chemistry has begun, because with human beings, there is a demand for chemistry. It is closely related to our life and is ubiquitous in our daily life. Yang Shixian, a famous skier in China, said: "Agriculture, light weight, eating, wearing and using are all inseparable from chemistry." Without the material civilization created by chemistry, there would be no modern life of mankind. ......
Question 6: How much does it cost to change a tire for dynamic balance? Hello, what brand of tires do you want to change? Different brands have different prices. The price of dynamic balance is different in different regions.
Question 7: Is the dynamic balance only for the first two tires or four tires? Generally, the front wheel only balances the first two tires. If you do all four rounds, you are doing four-wheel positioning, not balancing.
Question 8: Do I have to do dynamic balance every time I remove the tire? Because the weight on the hub is inconsistent, some places are light, some places are heavy, and so are the tires. When the tire is separated from the hub, the position of the newly installed hub and tire will change, that is, the original dynamic balance weight will also change. Therefore, it is necessary to rebalance and readjust the light parts of the wheel, that is, to give corresponding counterweights to the light parts. Rocks on bumpy wheels or tires can also affect the counterweight. Therefore, dynamic balance is recommended. I hope I can help you.
Question 9: What are the specific operation procedures of tire dynamic balance? What are the applications of intelligent wheel balancer in maintenance? When the steering wheel is shaking at high speed, or the wheels have some rhythmic abnormal noises, it may be that the wheels are going to be dynamically balanced. In addition, when the tire is replaced, the wheel hub is repaired, or the wheel is badly damaged and loses its balance weight due to bumps, the wheel must be dynamically balanced. Otherwise, it will cause abnormal tire wear and affect the stability of the vehicle. Wheel balancer is indispensable for wheel dynamic balance. The application of intelligent wheel balancer in maintenance greatly improves the maintenance efficiency. Advantages of intelligent wheel balancer Compared with ordinary wheel balancer, intelligent wheel balancer has some advantages. Can quickly find the imbalance point between the tire and the hub, and carry out position complementary correction; With intuitive screen display, it can better explain the existing problems to customers; It has an automatic inflation program, which can automatically measure the wheel diameter and the distance between the inner and outer edges. Some intelligent wheel balancers, such as Hunter GSP9700 tire vibration detection and control system, also have computerized tire measurement system that simulates road conditions. If a universal wheel balancer is used to balance the wheels, the wheels will still be unbalanced. However, if the simulated road condition measurement system of this equipment is used, the problems caused by non-dynamic balance can be solved. Some intelligent wheel balancing machines also have patented technologies such as automatic wheel locking device, automatic data measuring arm, foot data input key, automatic tire centering measurement, various lead block balancing methods, automatic balance point detection and stop. 2. Main structure of intelligent wheel balancer The main structure of intelligent wheel balancer includes driving device, rotating shaft and supporting device, intelligent display and control device, braking device, chassis and wheel guard. The driving device is generally composed of a motor and a transmission mechanism, which can drive the rotating shaft to rotate. The rotating shaft is supported by two rolling bearings, and each bearing has a sensor, which can convert power into electrical signals. The outer end of the rotating shaft fixes the wheel to be tested through a cone and a large pitch nut. The driving device, the rotating shaft and the supporting device are all installed in the chassis. The wheel cover can prevent the counterweight on the wheel or the inclusion in the pattern from flying out and hurting people when the wheel rotates. The braking device can stop the wheels. The display and control device of intelligent wheel balancer generally has an automatic diagnosis and adjustment system. The electrical signals collected by sensors are calculated, analyzed and judged by microcomputer, and then the unbalance value and phase are displayed. And it can automatically measure the rim diameter, rim width and the distance from the rim edge to the balancer housing (rim overhang size), which saves some preparation links. 3. The usage of the wheel balancer is as follows. (1) Remove dust, stones and old balance weights from the wheel to be tested. Check the tire pressure and inflate it to the specified value if necessary. (2) Select the cone according to the size of the center hole of the rim, carefully install the wheel and fasten it with a large pitch nut. (3) Turn on the power switch, and the equipment will start running. The system will automatically measure the rim width, rim diameter and the distance from the rim edge to the chassis. Press the start key, the wheel rotates, the balance test begins, and the control system automatically collects data. (4) When the wheel stops automatically or hears the "beep" sound, the system displays the unbalance amount and unbalance position inside and outside the wheel. According to the prompt, lift the wheel cover and turn the wheel slowly by hand. When two opposite arrows or related prompts appear in the indicating device, the rotation stops. Install the mass of the side balance weight displayed by the indicating device on the upper part of the inside or outside of the rim (the position of clock 12). Inside and outside should be carried out separately, and the counterweight should be clamped firmly. (5) There may be new imbalance after installing the counterweight, and the balance test should be carried out again until the balance reaches the specified value.
Question 10: How long does it usually take to change four tire wheels and do dynamic balance? About an hour. There is something wrong with the car, find the car master. 4S shop professional technician, 10 minutes to solve.
