Effect of fan blade parameters on fan performance

As the main part of the cooling fan, the fan blades, the change of its parameters will affect the performance of the fan. The following content is provided by Suzhou Santian Precision Mould Co., Ltd.:

1. Blade curvature: within a certain range, the greater the blade curvature, the greater the air volume and pressure at the same speed, and at the same time, the greater the resistance of the blade.

2. Blade smoothness: the blade surface is not smooth and flat, it will generate turbulence during rotation, increase friction and noise, reduce fan efficiency, and damage fan performance.

3. Blade spacing: If the blade spacing is too small, it will cause airflow disturbance, increase the blade surface friction, and reduce the efficiency of the fan; if the blade spacing is too large, it will cause insufficient wind pressure and also reduce fan performance.

4. Blade inclination angle: the greater the inclination angle, the greater the pressure difference between the upper and lower surfaces of the blades, and the greater the wind pressure at the same speed; when the wind pressure is too large, it will produce a backflow phenomenon, reducing the performance of the fan, so the blade inclination angle adjustment It should also be controlled within a certain range.

5. Blade tip clearance: If the clearance is too small, the airflow will rub against the blades and the outer frame, increasing noise; if the clearance is too large, the fan efficiency will be reduced due to the flyback airflow.

The difference between aromatherapy essential oils and essential oils

I purchased aromatherapy essential oil. Maybe, can I apply aromatherapy essential oil to my skin to achieve the effect? This is a question for many customers who purchase aromatherapy essential oils. Can aromatherapy essential oils be used directly like essential oils? This article is provided by the professional essential oil staff of Jiangxi Baicao Pharmaceutical Co., Ltd.

First of all, we need to know clearly that aromatherapy essential oils and essential oils are different! Aromatherapy essential oils cannot be applied directly to the skin like essential oils. Instead, they need to be dripped into an aromatherapy machine to create gas, and then people sniff to achieve the effect of essential oils. The essential oil can be applied directly or blended into various skin care products to repair and maintain the skin.

Although some essential oils can also be used as aromatherapy essential oils, aromatherapy essential oils should never be used as essential oils, only for aromatherapy. This is because the solvents of essential oils and aromatherapy essential oils are different. Aromatherapy essential oils are usually made with hydrophilic dispersants such as ethanol and isopropanol, so that they can be well dissolved in water, but these dispersants may cause allergy or other damage to people’s skin.

Essential oils are extracts of natural plant extracts without additives, which have health care functions, but are difficult to dissolve in water. According to this characteristic, it is also possible to judge whether it is essential oil or aromatherapy essential oil by whether it is easily soluble in water.

The above is the difference between aromatherapy essential oils and essential oils. When we use these two essential oils, we must make a distinction to avoid unnecessary damage.

4 ways to use essential oils

Natural essential oils are extracts extracted from plants by medical scientists and are used for body care and skin beautification. Some essential oils also have certain medical value. But how do we use essential oils in our daily lives? Jiangxi Baicao Pharmaceutical Co., Ltd. provides you with 4 kinds of essential oil daily use methods.

1. Apply to the skin

The most common method of using essential oils is to apply the essential oils directly to the skin and then massage to promote the skin’s absorption of the essential oils. This method is suitable for essential oils with firming skin, whitening skin, and promoting blood circulation and removing blood stasis, but some essential oils cannot be directly applied to the skin and need to be diluted with base oil before use. Before using it, you need to test whether you are allergic to this essential oil.

2. Incense, smell

You can drop the essential oil in the incense, and then smell the incense to achieve the effect of the essential oil. You can also open the cap of the essential oil directly and sniff under the nose, but some of the essential oil smells more irritating and not suitable for direct sniffing, so it is best to sniff through incense.

3. Bathing, soaking

You can drop the essential oil in the bathtub, and then let the essential oil enter the skin by bathing, so as to achieve the effect. This method can also be used for local soaking, which has a good effect on the treatment of surface skin. Before using it, pay attention to whether you are allergic to essential oils.

4. Take

Drop essential oils into water or food, and swallow them. This method of use cannot be used blindly by individuals. It must be under the advice of a doctor. At the same time, the essential oils to be taken also need to be sold by the hospital, and cannot be purchased in the store by yourself.

Is the fan capacitor broken? Probably these two reasons

If your cooling fan fails to start, maybe the capacitor of the fan has failed. Why does the fan’s capacitance fail? Let us explore together with Suzhou Santian Precision Mould Co., Ltd.

The capacitor is the main part of the fan blade rotation. It can produce a phase difference in the electromagnetic field or a torque in a fixed direction. If there is no capacitor, the fan will not rotate by itself after being energized, but you can push the blade with external force to make it work normally.

1. The capacity of the capacitor is reduced or lost. At this time, the electric fan will not start and run by itself, and it needs to fiddle with the blades to start. Although it can be started after using external force, the speed will be lower than normal speed.

2. The capacitor is short-circuited. In this case, the fan cannot keep rotating. You need to disassemble and check the internal parts of the fan to check the short-circuited parts. After repairing, the fan can be started normally.

The non-rotation of the fan is not necessarily damage to the capacitor. It may also be that the motor or coil of the fan is damaged, which may also cause the fan to not continue to work normally. However, it is not recommended to replace the motor or coil of the fan, because the price of replacement and repair is enough for you to buy a new fan.
