Polymer wear-resistant materials are mostly used for fan wear faults, mostly referring to polymer composite materials, which are mainly used for the repair of wear and tear of the transmission parts of the ventilator, because the material has stronger adhesion and compressive strength, it can be repaired without disassembly and machining, which has more advantages than traditional methods, and avoids the disadvantages of thermal stress of surfacing welding and high technical requirements for spraying. At the same time, due to the lack of metal concession of polymer composite materials, they can well absorb the impact vibration of the ventilator, avoid secondary wear, and become more and more mature in the application of solving the wear fault of the transmission part of the ventilator.

Ventilators are a very common household appliance whose operation and maintenance are important for both indoor air quality and home health. The following are the operation and maintenance methods of ventilators:1
The operation of the ventilator should start in the place where the indoor air is most polluted, such as the kitchen and bathroom. When turning on the ventilator, doors and windows should be closed to prevent outside air from entering the room.
Ventilators should be left running for at least 30 minutes a day to ensure that the indoor air is well circulated and fresh. 2.Maintenance:
The filter of the ventilator should be cleaned once a month to remove dust and dirt. If the ventilator's filter is dirty or damaged, it should be replaced with a new one. The motor and blades of the ventilator also need to be cleaned and maintained regularly to ensure the normal operation of the ventilator.
When using a ventilator, you should also pay attention to the following:1Do not allow the ventilator to run in the idle state to avoid damaging the differential dust opening motor.
2.Do not use excessive wind force to avoid affecting the balance and circulation of indoor air. 3.
Do not cover the ventilator during use, so as not to affect the ventilation effect. 4.Do not use a vacuum cleaner or detergent while the ventilator is running to avoid polluting the indoor air.
In conclusion, the operation and maintenance of ventilators is very important to help improve indoor air quality and protect the health of the home. If you are unsure how to properly use and maintain your ventilator, you can consult a professional or refer to the product manual.

Ventilators are widely used in various industrial sectors, generally speaking, centrifugal ventilators are suitable for small flow, high pressure places, while axial flow ventilators are often used for high flow and low pressure.
1. Ventilator for boiler.
Boiler ventilators can be selected centrifugal or axial flow according to the specifications of the boiler. According to its function, it is divided into boiler ventilator - conveying air to the boiler; Boiler induced draft fan – extracts the flue gas from the boiler.
2. Ventilators for ventilation.
This kind of ventilator is generally used for ventilation and heating and ventilation in factories and various buildings, and the pressure is not high, but the noise requirements are low, and centrifugal or axial flow ventilators can be used.
3. Ventilators for industrial furnaces (iron furnaces, forging furnaces, metallurgical furnaces, etc.).
This type of fan requires a higher pressure, generally 2940 14700N m2, that is, the range of high-pressure centrifugal fans. Due to the high pressure and large circumferential speed of the impeller, the impeller should have sufficient strength when designing.
4. Mine ventilators.
It has two kinds: one is the main fan (also known as the main fan), which is used to deliver fresh air to the downhole, and its flow rate is larger, and it is more suitable to use axial flow type, and there is also centrifugal type; The other is a local fan (also known as a local fan), which is used for the ventilation of the mine working face, and its flow and pressure are small, and explosion-proof axial flow fans are mostly used.
5. Pulverized coal ventilator.
Centrifugal fans are mostly used to transport pulverized coal in the combustion system of thermal power station boilers. Pulverized coal ventilators can be divided into two kinds according to different uses: one is the silo type pulverized coal ventilator, which blows the pulverized coal in the silo from its side to the furnace, and the pulverized coal does not pass directly through the fan, requiring the exhaust pressure of the ventilator to be high; The other is a direct-blown pulverized coal ventilator, which directly sends pulverized coal to the hearth.
Due to the serious wear of pulverized coal on the impeller and body shell, wear-resistant materials should be used.
Air-cooled mostly modular scroll machines, water-cooled water source heat pumps are screw, water source heat pumps have centrifugal is a new technology, only to come out, there are a few companies with such technical capabilities, Midea, Geri, Foton, etc. Energy efficiency air cooling is generally around, water sources are generally around 5, and centrifugation is currently known above the amount, which is quite energy-saving. There is not much difference in cost, and the more energy consumption is later, the more money is saved, but when the area is small, the module is selected, and the basic water source screw or centrifuge is selected when the area is large.
The problem of air quality cannot be solved by air conditioning, which only circulates indoor air. If you want air, you can only install an exhaust fan, and it is air convection. As for summer refrigeration, you can still get two one-to-two air conditioners, and it is best to use a ceiling machine. >>>More
