  • What are the forms of a centrifugal fan impeller?

    The front plate of the centrifugal fans is generally a straight front plate, a tapered front plate and the arc front plate. From the perspective of the gas flow trajectory, the impeller of the front plate of the tablet does not meet the gas flow trajectory. The leaves at the outer diameter of the impeller are much larger than the leaves in the inner diameter of the leaf wheel. Therefore, not only the speed of air flow in the circulation of the leaves, but also the airflow in the leaf flow in the...

  • How to improve the lubrication of centrifugal fans?

    Before we improve the lubrication effect of centrifugal fans, let's first understand the basic explanation of lubrication system. First of all, when we check the lubrication system, it is nothing more than improving the efficiency of the centrifugal fan, and everyone knows that the power of the lubrication system comes from the oil tank. Users often overlook the amount of oil stored inside. Eventually, when the oil reservoir is depleted, the parts wear out excessively. Therefore, we must pay att...

  • What is the basic principle of centrifugal fan?

    Centrifugal fans can be used for ventilation in general factories, warehouses, offices, residences, etc., and can also be used for air coolers (air coolers), evaporators, condensers, spray drops, etc. The anti-corrosion and explosion-proof axial flow fan adopts anti-corrosion materials and explosion-proof measures, and is matched with explosion-proof motors. It can be used to transport explosive, volatile and corrosive gases. It is required that the gas conveyed by the axial flow fan should be f...

  • What are the reasons for the vibration of the centrifugal fan?

    Centrifugal fans are used as auxiliary fan equipment for many production equipment. It is widely used in various production machines, but why does the centrifugal fan sometimes vibrate greatly? There are many reasons why centrifugal fans vibrate. Today, the editor will briefly understand with you in the following 5 aspects: 1. Reasons for the manufacture of centrifugal fans The fan manufacturer's quality requirements for the fan also affect the operation of the fan. If the parts are poorly proce...

  • What are the reasons for the imbalance of the centrifugal fan impeller?

    Centrifugal fan Negative pressure fan is a device that uses air convection and negative pressure ventilation to achieve forced cooling. It is mainly used in large places such as factories. However, in the process of using a negative pressure fan, various situations can occur, so let's talk about the reasons for the imbalance of the negative pressure fan impeller. Generally, the impeller of the negative pressure fan of the centrifugal fan can be divided into two reasons for unbalanced use: the we...

  • What are the categories of centrifugal fans?

    1. Ventilation fan can be divided into low pressure, medium pressure and high pressure centrifugal fans according to the working pressure. 2. According to the air intake mode, it can be divided into double intake fan and single intake fan. 3. According to the shape of the blade, it is divided into a forward-inclined centrifugal fan and a backward-inclined centrifugal fan. Second, the difference between the induced draft fan 1. The total pressure of the low-pressure fan is P≤1000Pa, the total pre...
