Belt drive of Roots blower
Belt drive is the common drive mode of Roots blower. It is an important component of Roots blower drive system, and plays an important role in momentum transfer between motor, roots blower and reducer. Whether the belt drive system can maintain reliable operation will directly affect the efficiency of Roots blower. With the extension of working time, the power transmission efficiency will continue to decrease, so improving the operation efficiency of belt drive system is an effective measure to reduce cost and improve efficiency. The friction between the pulley and the belt is the main driving force. The initial tension of the belt directly affects the power that can be transmitted and the life of the belt. Therefore, a new design method is proposed. The tension system is based on the experience of independent belt tension. The pressure adjustable spring is used to adjust the belt tension. After more than a year of use, the belt began to run. Smooth, so that the service life of the belt is greatly extended
1、 Transmission system composition
The belt driving system of Roots blower is mainly composed of fan pulley, load pulley, adjusting screw, tightening rod, tensioning screw and belt.
2、 Transmission application effect
The traditional way to adjust the belt of Roots blower is to adjust the tension of guide rail, which has the advantage of easy adjustment and maintenance. Any thing and system has advantages and disadvantages: the belt tension adjustment is not too tight or too loose, which will directly affect the life of Roots blower belt, at the same time, it will affect the use of Roots blower. In the most serious cases, the belt looseness or slipping will bring unnecessary faults to the fan, such as: the noise of the fan is increased or abnormal, and the speed and pressure of the fan are sudden Reduce a series of problems, all customers in the use of the process of each shift to check the belt tension, if there is loose must be adjusted.
3、 Description of the belt
The fan belt of Hongguang roots blower is imported triangle belt with big brands such as Dongyi of South Korea, gates of America and SamSung of Japan. However, the best V-belt has service life. The belt is a vulnerable part in the accessories of Roots blower. If it is normal fracture, please purchase and replace it. Practice shows that the service life of the belt with spring self tightening system is more than 12000 hours, which greatly prolongs the service life of the belt, saves the maintenance time and cost, improves the reliability of the system operation, and makes the service life of the belt double. economic performance.
4、 Belt installation
Usually, it has been assembled in the factory and we don't need to install it. However, some enterprises only replace the fan head or do not need our manufacturer's matching motor. Then you need to install the belt yourself. If the belt is damaged during use, it needs to be installed by yourself.
Conclusion: few customers choose the belt drive structure of Roots blower. This method is simple and flexible. If the air volume and speed of the fan are not enough, it can be adjusted slightly to achieve the effect of users. When replacing the belt, it is easy to replace and operate, as long as the front and rear pulley are in the same horizontal line.
