RB-81D-3 high-pressure exhaust fan with silencing device for air supplyworking principle

The impeller of a fan is composed of dozens of blades, similar to the impeller of a large gas turbine. The air in the middle of the impeller blades is subjected to centrifugal force and moves towards the edge of the impeller, where it enters the annular cavity of the pump body and circulates again in the same way from the starting point of the blades. The circulating airflow generated by the rotation of the impeller leaves the air pump with * energy for use. The fan adopts a motor, with a compact structure, small size, light weight, low noise, and no water or oil in the air source sent out.

Attention: Regardless of the brand of high-pressure fan, two aspects of protection are required: pressure and dust. The impeller adopts a multi blade single inlet centrifugal impeller made of galvanized or cold-rolled steel plate. The blades are designed based on aerodynamic principles. For pressure, a pressure relief valve is often used, which is an unloading valve. When the operating pressure of the high-pressure fan exceeds the set pressure of the pressure relief valve, except for the two bearings of the motor rotor, there is no direct contact friction in other parts of the vortex fan. The pressure relief valve will automatically open to release the excess pressure and protect the high-pressure fan. For dust, filters are often used.

In some special occasions, special protection is also necessary: for example, when using in a sealed environment, attention should be paid to ventilation and heat dissipation; When the ambient temperature (intake temperature is relatively high), it is more important to pay attention to ventilation and heat dissipation, or choose a high-pressure blower that allows for a higher intake temperature (currently, the domestic high-pressure allowable high intake temperature is 200 degrees);
For certain brands of high-pressure blowers, there may be their own usage recommendations. Before purchasing, it is important to have a detailed understanding.
1. The fan must be used and maintained by a dedicated person.

2. Fans are not allowed to operate with defects.
3. Regularly remove dust inside the fan, especially impurities such as dust and dirt on the impeller, to prevent rust and imbalance.
4. The maintenance of the fan must emphasize the importance of cutting off power and stopping the machine first.
5. Regularly check the sensitivity of thermometers and oil gauges.
6. In addition to replacing the lubricating oil after each disassembly and repair, the lubricating oil should be replaced every 3-6 months under normal circumstances.
