The pressure of the dust removal fan varies depending on the external resistance. When the load exceeds the motor, the motor will stop automatically. This is the thermal protection of the motor, because the load of the fan is exceeded and the large motor needs to be replaced.

The performance parameters of the fan mainly include flow, pressure, power, efficiency and speed. In addition, the magnitude of noise and vibration is also the main fan design index. Flow is also called air volume, which is expressed by the volume of gas flowing through the fan per unit time. Pressure is also called wind pressure, which refers to the increase in the pressure of gas in the fan, which is divided into static pressure, dynamic pressure and full pressure; The input power is the shaft power. The ratio of effective fan power to shaft power is called efficiency. The full pressure efficiency of the fan can reach 90%.

Conditions to ensure the safe operation of the blower When we use the product, we first need to check the tightening of each part and whether the positioning pin is loose. There is no oil leakage inside the blower body. There should be no scaling, rusting or peeling inside the blower body. Pay attention to whether the lubrication and heat dissipation are normal, pay attention to the quality of the lubricant, and often listen to the noise of the blower operation, pay attention to whether the unit is operating under non-compliant conditions, and pay regular butter. The overload of the blower is sometimes not displayed immediately, so pay attention to the increasing trend of intake and exhaust pressure, bearing temperature and motor current to determine whether the machine is operating normally.

The connection of blower temperature and service life The inlet temperature must not be higher than 40 ° C, usually through adjusting the inlet valve opening. 2, oil temperature, oil temperature is usually below 25 ℃, must not start; the temperature of the bearing should not exceed 65 ℃; if it exceeds 70 ℃, it should be stopped immediately, check the bearing surface for wear, and conduct research, usually requiring the bearing to contact / 2-3 percent on a square centimeter surface. The oil return temperature of the bearing is 50-60 ° C. If it exceeds 65 ° C, the temperature of the bearing shell can be overheated; when it is lower than 40 ° C, the bearing clearance is too large.

The cause of the high temperature of the blower: the running speed is too low and the belt slips.

After the blower base is installed and leveled, you can use a steel pipe tripod, chain block, or two wooden blocks temporarily erected on the installation site to hang the chain block, and then lift the blower to the base. Blower installation includes three processes: leveling, leveling and leveling.

Teach you how to distinguish between an axial fan and a centrifugal fan. If the air volume and pressure are the same, the power consumption of the centrifugal fan is higher than the axial fan, but the noise of the centrifugal fan is lower than the axial fan.

High pressure blower, also called high pressure blower, is different from general centrifugal high pressure blower. The high-pressure blower is small and easy to carry; except for the impeller, the high-pressure blower has no other moving parts, and the impeller is directly connected to the motor, without gears or drive belts, so it is highly reliable and almost maintenance-free.

The adjustment of the centrifugal fan is very important, because it can make the fan play its due role through adjustment, bring good economic benefits to the user, and carry out this work. The air inlet of the centrifugal fan has a large air outlet, so that the fan has the smallest resistance to the intake air, and the energy conversion is increased as much as possible to avoid losses. Therefore, this specific requirement will be met. Moreover, if the size of the air inlet and the air outlet are the same or smaller than the air outlet, it will affect the conversion of effective work and the static pressure of the fan will be reduced.
