Is it OK to apply cooking oil and then motor oil to an electric fan?

Edible oil can not be used as fan lubricating oil, edible salad oil is a vegetable oil that has been decolorized and refined, but its composition contains saturated fatty acids and unsaturated fatty acids, which are easy to rancidity and deterioration when placed in the air for a long time, especially under high temperature conditions, resulting in corrosion of bearings.

Lubricating oil is mostly processed from mineral oil, and according to different conditions of use, there are lubricating oil and grease. Lubricating oil can be roughly divided into high-speed and light-load, high-speed and heavy-duty, low-speed and light-load and low-speed heavy-duty according to the different use environment. The lubricating oil for fan motor bearings is a high-speed and light-load category, and the common sewing machine oil can generally be used as lubricating oil.

If you have gasoline, don't apply cooking oil. Cooking oil is not as pure as gasoline and has impurities. But there really is no engine oil to replace with some cooking oil, and I have done this.

It is added to a ring-shaped sponge inside the motor.

First of all, take out the fan blade and take out the motor. There is a ring-shaped sponge inside the motor, and then the sewing oil is dripped, and the drip is full. Finally, put the electromechanical into the fan holder and fix the motor. After installing the fan blades, attach the back cover and screw it.

1. First of all, take out the fan blade and take out the motor.

2. There is a ring-shaped sponge inside the motor, and then drip the clothes car oil on it and fill it up.

3. Finally, put the electromechanical into the fan frame and fix the motor.

4. After installing the fan blades, install the back cover and screw it.

Precautions; 1. Don't add too much oil in the vertical motor, otherwise it is easy to leak.

2. When disassembling the electric fan, be careful not to remove the screws.

The electric fan should be filled with lubricating oil before using it every year, so as to ensure the normal operation of the fan and the electric ear dryer.

Some of the places where the electric fan is filled with lubricating oil can be operated outside the machine: there is a fuel filler port on the top of the motor shell, and the oil filler is blocked with a plug, and when you open the plug, you can see that there is a small hole, which can be refueled with a sewing machine oil can.

Edible oil will become sticky after being in the air for a long time, which is not conducive to lubrication.

Regarding the problem of high electrical noise, there can be the following reasons and solutions:

1. The fan is short of oil. You can turn on the computer host, find out which fan is ringing, and then gently open part of the label in the middle of the fan, go out of the bearing inside, add a little lubricating oil to the bearing, and then seal the label tightly.

2.The fan is dusty. Find the fan that is ringing and clean the dust on the top of the fan and the middle bearing part.

3.The fan bearing is faulty, or the fan is not stable. The easiest way to do this is to replace it with a new fan, <>

4.The fan is fault-free. But what you set in your computer's BIOS is the CPU fan at full speed. In this case, the fan will not adjust the fan speed according to your usage, so the fan will rotate at full load when turned on, resulting in a lot of noise.

Remove the fan, and a self-adhesive garden piece will be pasted on the side of the fan against the heat sink. Lift the garden piece and you can see the fan shaft. If the inside is relatively clean, a drop of light lubricant can be added directly is sufficient.

If you find it dirty, you need to remove the rotor and clean it. You can find a baffle at the end of the shaft, and you can remove the baffle carefully to remove it and clean it. You can clean it with gasoline or anhydrous alcohol, wipe it clean, wait for it to dry thoroughly, and then refuel and reset the rotor.

Finally, paste the self-adhesive garden sheet, and you can install the heat sink on it.

Some fans can tear off the label on the fan to refuel, but some fans cannot, so they can only remove the blades and take out the bearings for refueling. with oils with liquids, such as sewing machine oil; There are others, such as butter and so on, sometimes you can mix and add them, and you can buy a little better oil to use if you have the conditions.

Use a straw to take a small amount of sewing machine oil (transformer oil) and drop it into the rotating part of the fan, which is the inside of the coil, and then manually select the fan, and it feels stable.

Lubricating oil for computer fans, engine oil and lubricating oil for automobiles can be used.

Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles, machinery and equipment to reduce friction and protect machinery and processed parts, mainly playing the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering (ROAB).

Lubricating oil is generally composed of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil, and additives can make up for and improve the shortcomings of base oil performance, give some new properties, and are an important part of lubricating oil.

Base oils. Lubricant base oils are mainly divided into three categories: mineral base oils, synthetic base oils and biological base oils.

Additive. Additives are the essence of modern high-grade lubricating oil, and the correct selection and reasonable addition can improve its physical and chemical properties, give new special properties to the lubricating oil, or strengthen its original certain properties, and meet higher requirements. According to the quality and performance of lubricating oil requirements, the additives are carefully selected, carefully balanced, and reasonably blended, which is the key to ensure the quality of lubricating oil.

Generally, commonly used additives are: viscosity index improver, pour point lowering agent, antioxidant, cleaning and dispersing agent, friction relieving agent, oily agent, extreme pressure additive, antifoam agent, metal passivating agent, emulsifier, anti-corrosion agent, anti-rust agent, demulsifier, antioxidant and anti-corrosion agent, etc.
