Direct connected roots blower
The new type of three leaf roots blower is divided into two types: belt drive and direct connection drive. We have made a rough introduction to the belt drive form before. Today, honghongguang editor will talk about it Direct connected roots blower.
Direct connected roots blower It is a direct connection between the motor and roots blower through the coupling, but it does not change the fan speed to control the flow. The fan speed must be synchronized with the motor speed. This connection avoids replacing the V-belt. And adjust to improve the mechanical efficiency, three leaf roots blower matching motor is 4-stage motor, 6-stage motor, 8-stage motor, the specific motor to be used depends on the pressure and air volume of Roots blower required by customers.
Belt drive of Roots blower and Direct connected roots blower The difference is as follows:
Advantages of belt drive: fan speed can be selected in a wide range, and the flow rate is closer to the actual application. Disadvantages: belt drive requires tension and additional lateral force is added to the fan shaft end. The advantages of direct drive: the fan shaft has no side force and high transmission power. Disadvantages: direct connection to the motor, low optional speed. In most cases, the volume of the fan is too large, and a bypass pipe needs to be installed to empty it, which consumes a lot of power. The speed of the main shaft of the fan can be adjusted freely according to the ratio of the motor and the belt pulley of the fan.
The manufacturer can make any combination, so the flow range and pressure range of the connected roots blower are widely available on the market, while Direct connected roots blower It can only be a fixed speed, and the speed of the fan spindle is equal to that of the motor. Speed, the same type of fan, the same level of motor flow can only be fixed, this is the difference in air volume! Secondly, due to different applications, ironmaking and other high-temperature working environment generally adopts direct connection mode, the belt is not resistant to high temperature, is not easy to slip, is not easy to break. If the belt is in high electrostatic condition, the ordinary belt cannot be used, and the belt can be used for direct joint of belt or bronze.
Summary: Direct connected roots blower There are also dozens of models and hundreds of size parameters for customers to choose from. Direct connection and belt have their own advantages and disadvantages. There are no special requirements. Generally, the belt is used, and the maintenance is simple. If there is any difficulty, you can choose to buy it according to the size, temperature and price of the base. Note: in the process of installation, the fan and motor must be balanced, and the mounting base must be flat.
