Does Roots blower need to heat the water cooling pipe in winter?

There are water-cooled roots blowers in roots blowers, most of which are double stage series fans. Single stage boosting cannot be achieved, so double stage boosting is required. The higher the pressure is, the higher the temperature of the whole machine will be, and the higher the temperature will have an impact on the equipment. Therefore, the gas needs to be cooled before the secondary boosting. There are two cooling modes for roots blower, one is water cooling and the other is air cooling. Single stage roots blower mostly adopts air cooling, and double stage series blower mostly adopts water cooling.

In winter, in northern China, especially in Northeast China, Inner Mongolia, Gansu and Xinjiang, if two-stage series Roots fans are used, do you need to heat the water cooling pipes before the Roots fans are used?

Xinqian Shun Fan Answer: In fact, heating is not necessary. The correct operation method is as follows: when using Roots blower in winter, drain the water in the water-cooling pipe after use, and fill the water before the next use. As long as the fan is working, the water-cooling pipe will not freeze.

As for submerged roots blower, it is generally not used in the north. This type of roots blower can place the blower in water, which has obvious advantages. First, it can reduce the temperature of the machine body, and second, it can effectively reduce the noise of the blower, but there are also obvious shortcomings. It cannot be used in winter in the north, and maintenance is inconvenient.

What should be paid attention to when using water-cooled Roots blower in winter? In the north, the temperature is low in winter. After the Roots blower is used, the water-cooled Roots blower must completely drain the water in the water-cooling pipe, or frost cracking will occur. The water cooling pipe is frozen and cracked, causing serious damage to the fan.

When using the water-cooled Roots blower, we also have the following suggestions. The water-cooled Roots blower is mainly for cooling the bearing and rotor of the fan. When using the Roots blower, we recommend you not to stop the cooling water circuit, which can reduce water consumption and save water. If you stop the water circuit, the following situations may occur:

1. No matter how low the outdoor temperature is, the heat dissipation of the key parts of the equipment cannot be guaranteed. Once the operation time is too long, the temperature will rise to very high, which will cause trouble if the bearing is damaged;

2. Most Roots blowers are made of cast iron. If you shut down the cooling water and the equipment will produce a little temperature rise, it is easy to rust the cooling pipes. Even if winter has passed, the cooling water will be blocked in summer, which may lead to poor heat dissipation and damage to the equipment.

The two-stage series Roots blower is still widely used. In the process of use, many customers have problems, most of which are caused by being unfamiliar with the equipment. After we purchase Roots blower, we must have a certain understanding of the use of Roots blower and operate it scientifically and reasonably.
