For many households, air conditioning and electrical fan products are generally purchased, but in the actual use of air conditioning at a later stage it appears that, because of the relative high cost of air conditioning, most users, especially when the weather is not very hot, choose to use electrical fan products. It was therefore important to have common failure maintenance treatment of fans. So the message for you today is about the maintenance and handling of the fans。
I. How can you fix a fan
No buzz. First, check if the heat protection smelt is burned (a small, white one tied to a circuit) and can be connected directly。
2. If the wind leaves do not move and the electricity is buzzed, the bearings are dry, and the two-end bearings are accompanied by a few drops of dense oil (which will soon volatilize), then the power is forced to move until flexible。
Three, the light buzzes, and it doesn't turn up: replace it with a 1~1. 2uf good capacitor; it doesn't turn up, it starts the circuit break, it burns。
If it is proved that the circuits were burned, the purchase of a good fan generator would be about $20, and the cost of bypassing one would be more than that。
Ii. Common failures of electrical fans and solutions
Many families now have air conditioners and there are many air conditioners, so many families are willing to use electric fans when the weather is not hot. Sometimes electric fans are not used for a year, and it is not easy to get them out, and sometimes they can solve problems themselves. Here's to share with you the common failure of electric fans and their solutions。
1. Maintenance of non-rotation of fans
The main reasons for the non-turning of the electric power are the break-up of the circuit, the lack of oil for the axle, the abnormality of the electrical capacity, etc. The latter two types of failure are most evident in the maintenance practice of electric fans. For the non-turning fans, my steps of repair are to detect plugs, switchers, volume, reprocessing。
The first step is to measure the operation of the electrical fans and the velocity around groups. First, turn the fan the timer, and when you hear the sound, make it normal. If no sound, indicate that the timer is damaged. If there's no resistance value, it's probably the electric circuits burning off the road. Thermal breakers may open circuits for electrical units with a chain of heat breakers, and should also be detached to see if the short-link heat breakers return to normal. The slot switch is all damaged, but not likely。
The second step is to check if the axle is carried, to remove the fan shield, to rotate the axle by hand and, if not, to indicate the gravity of the axle. Dismantling the power plant, removing the oil stains and rusts from the front, front and back axle and then putting foot on the back, back and back axle, sewing machines, oil, most of the electric fans were able to debug。
The third step is to measure the start-up capacitor, which is measured if the axle rotates flexibly. First of all, the electrons are measured at the end of the capacitor and the electrical resistance values of the entire fan circuit, i. E., black and yellow wires, are operated, activated and retrofitted, using a single table rx100 series。
The maintenance of electric fans
I'm in place one step at a time for an electric fan. As noted above, maintenance is carried out on a systematic basis. If the user says so, the fans turn slowly and then gradually fast. Based on experience, it is usually a light hold of an electric engine. This was due to the initial absence of oil for electrical fans. Directly unplugging the fans and adding foot-sewing oil to the back and back axle。
Remote control, fan. The power goes off, it goes off
The remote fan control execution element is now basically a controlled silicon. It is understood from the principle that the controlled silicon substance is equivalent to the powered silicon piercing of the switch is equivalent to the connection of the switch. Of course the power fans turned。
For example, when a remote remote-controlled fan is used, remote-controlled functions are generally normal, but when it closes, it does not remove the power hand-held fan with a clear vibrating sense, and it hums, and it is particularly visible at night that the fan leaves are moving slowly. Because the controls are basically normal, the cmu is normal, and it's clear from the principle that the controlled silicon is malfunctioning
An electric fan power plant is a component that plays an important role in an electrical fan product, and its presence can provide some assurance that the user is well served and that the desired effect can be achieved as far as possible. It can cause some trouble if the electric fan power is damaged or malfunctioned. The information presented for you today is then based on the contents of these plates, which are described above as knowledge of the maintenance processing steps and the usual operating methods of the fans。
