Height requirements for ventilation axial fans in the fuel pump room

For this height requirement, normally, look at the area of your pump room, and then according to this location, it is not lower than 60, and there is no problem with the rest.

Axial fans are widely used in various industrial occasions and are very widely used in fans. The shape of the axial fan is a bit like an electric fan, with a central shaft, and the four fan blades will follow this central shaft to form an axial running fan. Because of the fluidity of this fan gas, it is suitable for use in places with relatively low pressure, so let's take a closer look.

Ordinary axial fans can be used for ventilation in general factories, warehouses, offices, residences and other places, and can also be used for air coolers (air coolers), evaporators, condensers, spray drops, etc., there are also mining axial fans, anti-corrosion, explosion-proof axial fans use anti-corrosion materials and explosion-proof measures, and match explosion-proof motors, which can be used to transport explosive, volatile, corrosive gases, and require that the gas transported by axial fans should have no significant dust, no viscous and fibrous substances; The temperature of the direct connection type of the motor does not exceed 40, and the temperature of the belt drive type does not exceed 60.

The amount of dust of the conveyed gas shall not exceed 150mg m3, and the axial fan is mainly composed of impeller, casing, motor and other parts, and the bracket is connected with the casing duct by section steel. Among them, the impeller and casing of the anti-corrosion axial fan are made of fiberglass, and other types of axial fans are generally made of steel plates.

When the impeller rotates, the gas enters the impeller axially from the air inlet, and is pushed by the blades on the impeller to increase the energy of the gas, and then flows into the guide vane. The guide vanes deflect the gas flow into axial flow, while the gas is directed into the diffuser tube, which further converts the kinetic energy of the gas into pressure energy and finally into the working line. Axial wind turbine blades work in a similar way to the wings of an aircraft.

However, the latter is to act lift upwards on the wings and support the weight of the aircraft, while axial fans fix the position and move the air. The cross-section of an axial fan is generally a wing profile.

The height requirements of the axial fan in the fuel pump room are required to change the air flow between the gas pressure regulating room for 3 times and for 8 h accident ventilation during mechanical ventilation; 10 hours of mechanical ventilation in the fuel pump room; Fuel tank depot 6 times h mechanical ventilation.

The height of the ventilation axial fan in the fuel pump room requires that the axial fan can be close to the ground and upward.
