Adjust the motor, hydraulic coupling, when the coupling between the roof axial fans, using the following two methods are inappropriate alignment: 1, by coupling halves are not in contact with a dial indicator fixed on a stationary coupling halves, the roof axial fans allow probe to measure the other rotary coupling halves radial and axial runout. 2, to help assist with a feeler flat block radial and axial runout. 3, the roof to adjust the axial flow fan with horn dimensions, the horn is applied between the base plate and the horn, and when to tighten each bolt to ensure that the bolt force is substantially uniform. 4, the roof axial fans use pump lubrication, running bearings are generally not lose oil, so when the slinger damage dwt series roof fans, too lazy to fill due to the inconvenience of installation and equipment. 5, fan slinger role in that encounter unexpected roof axial flow gas station outages or short fault and not the normal supply, the oil ring from the bearing housing oil pool will lift oil to supply certain bearing The oil, to ensure its continued rotation without damage, so must not be missing. The roof is a common axial fan, ventilation fan installed on the roof of the axial fan category inside a special glass blower steel roof fan manufacturers, the same principle and axial fans roof fan, widely petroleum, chemical, textile, metallurgy, power plants, machinery factories, laboratories, warehouses, pharmaceutical, food processing and other industrial enterprises as the main air supply and exhaust equipment. The main discharge roof fan heat, smoke exhaust ventilators common, such as the role of ventilation. Applies to: No motor oil turbine roof fans, chemical, textile, metallurgy, power plants, machinery factories, rubber, offices, laboratories, warehouses, pharmaceutical, food processing and other industrial enterprises and senior civil air supply and exhaust ventilation.
