Boiler ventilation and combustion assisting medium pressure blower

Boiler ventilation and combustion assisting medium pressure blowerAttention to use and maintenance:

1. The high-pressure vortex fan should be placed in a relatively stable place, and the surrounding environment should be clean, dry, and ventilated.

2. The rotation direction of the impeller must be in the direction indicated by the arrow on the fan casing.

3. During operation, the working pressure should not exceed 8kPa to avoid excessive heat generated by the air pump and damage to the air pump caused by motor overcurrent.

4. Except for the two bearings of the motor rotor, there is no direct contact friction in other parts. The installation method of bearings for this air pump is mainly divided into two categories. *The bearing at the end of the class air pump is installed in the pump body between the motor base and the impeller, and this type of air pump does not need to be lubricated normally. The bearings on the second type of air pump end are installed in the middle of the pump cover, and the bearings on this type of air pump end should be regularly lubricated with grease (7018 high-speed grease). Once a month, for air pumps that work continuously in three shifts, the refueling frequency should be increased. The maintenance and upkeep of the bearings on the motor and fan end of this type of air pump shall be in accordance with the * type of air pump.

5. The filter screens and noise reduction devices at both ends of the inlet and outlet should be cleaned in a timely manner according to the situation to avoid blockage and affect use.

6. The external connection of the inlet and outlet must be made using flexible hoses (such as rubber hoses or plastic spring hoses).

7. Bearing replacement: Bearing replacement must be carried out by personnel familiar with repair work. First loosen the screws on the pump cover, and then disassemble the parts one by one according to the order shown in the diagram. The disassembled parts should be cleaned, and then assembled in reverse order. When disassembling, do not forcefully pry the impeller, use a roller to remove it, and do not miss the adjusting gasket to avoid affecting the clearance that has been adjusted before leaving the factory.

8. It is strictly prohibited for solids, liquids, and corrosive gases to enter the pump body.

Regardless of the brand of vortex blower, two aspects of protection are required during use: pressure and dust.

For pressure, a relief valve is often used, which is an unloading valve. When the operating pressure of the high-pressure blower exceeds the set pressure of the relief valve, the relief valve will automatically open to release the excess pressure and protect the vortex blower.

For dust, filters are often used. It often uses filter cartridges with different filtration accuracies according to different usage scenarios. Different filter cartridges have different maintenance methods and service lives, which need to be clarified when ordering.

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 vortex blower that allows for a higher intake temperature.
