As a common centrifugal compressor, Roots blower is widely used in industrial production of air transport, exhaust and pressurization and other fields. However, in the long-term operation, the root blower often has the problem of excessive temperature, which has a certain impact on the stable operation and service life of the equipment. Therefore, it is particularly important to understand the causes of high temperature of Roots blower and the corresponding treatment methods.

First of all, let's explore the reasons that may cause the root blower temperature to be too high:

1. Overload operation: If the Roots blower runs beyond the rated working load for a long time, the internal pressure of the equipment will be too high, which will cause the blower temperature to rise.

2. Poor lubrication: the inside of the Roots blower needs to use lubricants to reduce friction and wear and ensure the normal operation of the equipment. If the lubricant fails or the lubrication is insufficient, it will lead to increased friction, which will increase the temperature.

3. Loose belt: Roots blowers usually use belt drive, if the belt is not tight enough or loose, it will lead to a decrease in transmission efficiency, an increase in blower load, and an increase in temperature.

4. Air inlet blockage: If the air inlet of Roots blower is blocked, it will affect the normal air supply of the blower and cause the working temperature to rise.

Faced with these reasons, we need to take appropriate treatment methods to solve the problem of excessive temperature of Roots blower:

First of all, it is necessary to ensure that the Roots blower operates within the design load range. Reasonable planning of process parameters to ensure that Roots blower operation does not exceed the rated load. If you need to increase production, you can consider increasing the number of devices or supplementing them in other ways to avoid overload operation of a single device for a long time.

Secondly, it is necessary to regularly check and replace the lubricant of the blower. According to the equipment usage and manufacturer's recommendation, set the lubricant replacement cycle, and ensure that the lubricant is used in accordance with the specification. In addition, attention should also be paid to the operating state of the blower bearing, and lubricating oil should be added in time to reduce friction heat production and reduce temperature.

At the same time, it is necessary to check the belt tightness of the blower frequently to ensure that the belt tension is moderate. The tightness of the belt can be adjusted according to the operating load and working environment of the equipment to avoid the problem of temperature rise caused by loose belts.

In addition, the air intake of the blower should be cleaned and maintained frequently. Regularly remove debris and dust around the air intake to ensure the normal suction of the blower, and ensure that the air intake is smooth, thereby reducing the increase in temperature.

In addition to the above methods, the temperature can also be reduced by increasing the cooling device of the blower. For example, in the design stage, additional equipment such as radiators, air coolers or water coolers can be considered to effectively reduce the operating temperature of the blower.
