What is the maximum temperature of roots blower? Methods for cooling roots blower:

The general Roots blower does not require high manufacturing technology. High temperature roots blower has high requirements for manufacturing technology. Generally, the suction temperature of Roots blower is 40, and the discharge temperature varies with pressure, but it is usually below 140. If the outlet temperature is higher, it needs cooling treatment. Roots blower will produce certain temperature during operation, and certain technical measures shall be taken to prevent equipment parts from being damaged by high temperature.

Roots blower has sound insulation device, so please be sure to open the sound insulation cover in summer. The sound insulation cover forms a closed space, which increases the ambient temperature, the temperature of the suction air increases, and the outlet temperature is also very high. The inlet temperature of most Roots blowers equipped with acoustic enclosures will exceed 45 ℃ in summer. If the fan is set indoors. Air conditioners can be installed if conditions permit. Don't worry about air conditioning and electricity. When the temperature of the motor rises by 10 degrees, the expected life will be quite low.

Therefore, indoor air conditioning can extend the life of equipment and reduce the outlet temperature. Reducing the pressure at the inlet and outlet helps to reduce the temperature. In general, we should keep the equipment ventilation normal, especially in summer, we should properly open the soundproof setting door for Roots blower with soundproof equipment, set the air conditioning blower to reduce the surrounding temperature, reduce the inlet and outlet pressure, reduce the temperature, reduce pipe bending, etc., and reduce the pipeline pressure loss and other pressure losses

1. Auxiliary cooling measures

Generally, the cooling of Roots blower is divided into water cooling and air cooling. Air cooling can be used under the technical requirements. Water cooling is required when the temperature is high. In order to ensure the normal use of the main and auxiliary oil tanks, cooling treatment is also required to reduce the temperature of the lubricating oil. The temperature of general lubricating oil shall not exceed 65. Attention shall be paid in winter. When the water-cooled roots blower is not used for a long time in winter, the water in the cooling pipe shall be discharged to avoid freezing and cracking of the cooling pipe.

2. Impeller clearance design

During the design of Roots blower, the clearance between impellers will also affect the heat dissipation. Such as shell clearance, impeller clearance, wallboard clearance, etc. These are also the key points of design. The design of some small manufacturers is not in place, so the service life of the equipment will be shortened. The design of impeller clearance must meet certain standards, and must be checked during use. During the annual major inspection, the dust pollution on the impeller shall be treated to ensure that the clearance of the impeller is within the standard error, and the clearance is not too small.

3. Strengthen the protection of vulnerable parts

The lubricating oil is easy to be damaged by roots blower at high temperature, so the cooling treatment of lubricating oil needs various protections. Not only need water cooling, but also need to reduce the temperature from the inside of the chassis to the wall panel and lubricating oil for cooling treatment.

The above is about the temperature that the Roots blower can adapt to. I hope it can help you. If you have any questions, please feel free to consult the manufacturer of Roots blower at 0531-83663588
