The use of centrifugal fans and the main components
Usually, centrifugal fan equipment is used for ventilation and air exchange. So, what are the main contents of its use conditions you know? Generally speaking, the application of centrifugal fan equipment is mainly used in general factories and large buildings, which can be used not only as input gas, but also for output gas in the process of ventilation and air exchange. The following together to see the details.
For the centrifugal fan, whether it is used to transport gas or input gas, the main types of gas applicable to: air and other non-spontaneous combustion, harmless to humans, non-corrosive to steel materials. And it is required that there must be no sticky substances within the gas, and the dust and hard particles contained therein must not exceed 150 mg per cubic meter. The temperature of the gas also needs to be controlled within eighty degrees.
Next, let's take a look at the main components of the centrifugal fan. In fact, the main structural components of the equipment are the impeller, the casing and the air inlet. Its impeller is generally made of steel plate, and in the process of making it will go through static and dynamic balance is more positive, so it can ensure its good air performance, high efficiency and smooth operation.
So, when making the casing of the centrifugal fan equipment, what issues need to be noted? Usually, the housing of the equipment can be divided into two different types. For example, it can be made into a whole and cannot be separated, or it can be made into a triple-open type and connected with bolts. In addition, the air inlet of the equipment is usually made into a convergent streamlined whole structure, which is bolted near the inlet of the equipment.
To introduce the transmission part of the centrifugal fan equipment, the transmission parts are an important part of the equipment, including the main shaft, bearing box, rolling bearings, pulleys or couplings and other components. Among them, the main shaft is made of high quality steel. And it is equipped with thermometer on the bearing housing and lubricated with bearing grease.
Fan as a common factory equipment, for friends working in the factory will not feel unfamiliar, in fact, the fan because of the frequent and continuous work, so it is easy to have some damage, usually for the fan must do a good job related to maintenance work to
Low noise centrifugal fan selection needs to pay attention to which points? As the fan get the wrong model specifications will jeopardize the normal application. The key performance parameters of the fan are output power, air volume and working pressure.
Before installation, all parts of the fan should be thoroughly checked. Whether the machine is complete, whether the direction of rotation of the impeller and the casing is consistent, whether the connection of each ministry is tight, whether there is damage to the impeller, spindle, bearings and other major parts, whether the transmission group is flexible and so on. If problems are found, they should be repaired and adjusted immediately.
