The positive and negative poles of the filter pump are connected in reverse.

Aiya, if the positive and negative poles of the generator slip ring were connected in reverse, he couldn't just leave it alone. First of all, he had to quickly cut off the power supply. He couldn't let it continue to work in the case of a wrong connection. Otherwise, it might cause a lot of trouble, such as damaging the equipment. After that, he had to carefully re-connect the positive and negative poles. If he wasn't sure what to do, it would be best to find an experienced technician to deal with it. After all, they were professional and could guarantee that the matter would be resolved safely and correctly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

If the positive and negative poles of the motorcycle battery were connected in reverse, there could be many serious consequences. It was not as simple as the battery running out of power. First of all, it might blow the fuse and cause the entire car to lose power. Secondly, it could even burn the wires and other parts of the motorcycle. It could even cause the motorcycle to catch fire and the battery to be scrapped. In addition, when the positive and negative poles of the battery were reversed, there would be a continuous discharge, which was also a kind of damage to the battery itself. Therefore, when the positive and negative poles of the motorcycle battery were reversed, the battery was out of power. It was likely that the battery had been damaged and needed to be checked and repaired. If necessary, the battery should be replaced. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

If the positive and negative poles of the charger were reversed, the resistance of the charger and the electronic components of the power supply might be burned. When the charging connection was reversed, there would be a large current flowing through the battery and the charger. Because the current was too high, the battery would heat up violently, causing the plate to swell and be damaged. The active material would fall off, reducing the power storage and service life. The charger might have a situation such as burning the high-power resistance surface at the output end. For a battery charger with anti-reverse connection function, if the positive and negative poles were connected in reverse, there would be no voltage output. In this case, the charger itself might not burn the components, but it would not work normally. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Most types of membrane type measuring pump do not have clear requirements for steering. Some types of pump may cause adverse effects on gears, turbine, and worm when reversing. There will also be noise and vibration during operation. It is recommended to confirm with the manufacturer whether there is a clear steering requirement. If there is no clear regulation, there is no need to consider the steering problem. However, there were also measuring pump's motor that could only rotate in the forward direction. If it was rotated in the reverse direction for a long time, it would damage the transmission mechanism. From the rear end of the motor, the rotation direction of the motor was clockwise. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

When the positive and negative poles of the electric car charger were reversed, it would not explode, but it would burn the charger's rectify component and high-frequency transformer. Because the voltage of the battery and the charger were added during charging, the current would flow into the charger in the opposite direction and would not be controlled by the circuit, which might burn the charger. If the charger fuse is not broken, if the output part of the copper foil is blown after opening the charger (this situation is usually caused by the positive and negative poles), it may return to normal after connecting the broken copper foil and replacing the damaged components. There were also cases where the E-shaped circuit was burned, and it could be repaired by reconnecting it (this method was shared by non-professionals). In addition, a short period of negative and positive reverse connection may not have much effect on the battery, but it will burn the battery over time. The degree of battery damage is directly proportional to the length of reverse connection. If the battery is charged in reverse, it is equivalent to a short circuit, and the battery may burn or explode. When using, try to use the original charger or the same model to avoid the occurrence of the positive and negative pole connection. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Different brands of camera batteries had different positive and negative labels. For example, Lingye camera batteries had positive and negative labels; Canon original batteries did not have positive and negative labels; Green Giant Rechargeable camera batteries had positive and negative contacts in the slot and positive and negative labels beside them. In the case of a camera charger connected to a camera, the positive and negative poles were not on the side of the camera or charger alone. Nowadays, it was mostly a wire or plug type, usually with the positive pole inside and the negative pole outside. In addition, in the charging flashlight, the red power cord was connected to the positive battery, which could be used as a reference, but the connection of the camera battery needed to be determined according to the specific product. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The Elantra engine oil filter was a positive thread. When installing, rotate it clockwise according to the thread. When dismantling, use a wrench to loosen it in the counterclockwise direction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The negative and positive poles of the phone battery might cause the current to be abnormal, which would trigger the battery protection mechanism. The phone would automatically enter the white screen state for safety, but this did not mean that the screen was burnt. There were also opinions that modern mobile phones had reverse phase protection, so the battery would not burn the phone parts because of the positive and negative poles, but the phone might not be able to turn on. However, there was no clear indication that the battery's positive and negative poles would directly burn the screen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

If it was an ordinary light bulb, it usually did not need to be divided into positive and negative poles. As long as the circuit was connected in the opposite direction, it would still emit light. However, there might be situations such as open circuit and reverse breakdown, but there would not be a short circuit (usually with a current limiting resistance). Different situations needed to be analyzed in detail. If it is an LED lamp, when it works under the direct current power supply: if the direct current power supply is less than 5V, even if the positive and negative poles are connected in reverse, there will be no reverse breakdown; if the direct current power supply is between 5V -30V, the positive and negative poles are connected in reverse, the situation is complicated; if the direct current power supply is above 30V, the positive and negative poles will be broken down in reverse.(However, this situation is rare, because usually the LED power supply will not exceed 30V); If the LED is connected to an AC circuit above 30V (such as a 220V AC power supply LED indicator circuit), the LED will definitely be broken down in the negative half cycle of the AC power supply. If you find that the positive and negative poles of the lamp are reversed and do not light up or there is a problem, you should first cut off the power supply and then connect the positive and negative poles correctly. For bulbs or LED lights that may be damaged, it is necessary to check whether they can still work normally. For example, the LED lights may need to be checked whether they are broken. If they cannot work normally, they may need to be replaced. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
