The Roots pump temperature is very high
Thread Content
The company has two sets of Roots pumps; one set operates normally, while the temperature of the other set keeps rising, reaching over 100 degrees at its highest. The water pipe is not blocked, and there is a buffer tank in front of the air inlet. The manufacturer also tried to repair it, but it didn’t work. I would like to ask everyone how to lower the temperature.
First, check the intake air temperature, the evaporation rate of the vacuum device in use, and the condensation efficiency of the condenser. Check again the issues with the vacuum pump, the condition of the lubricating oil, the condition of the bearings, as well as the clearance of the rotor and the clearance with the end caps. Also, check whether the exhaust is unobstructed and free of resistance.
First, determine whether this issue has existed since installation; if it only appeared recently, check whether the condenser is clogged (if one is present). Also, examine the oil level, ensure that the right type of oil is being used and that the oil is clean, verify that the bearings are properly installed, check whether the rotor is rubbing against the wall plates, ensure that the bearing caps are not too tight, and determine whether the bearings are damaged
The information provided regarding the issue is incomplete; which location has a high temperature? Two sets of Roots pumps connected in parallel to the buffer tank? What is the difference in outlet pressure between the two groups of Roots pumps? Are the parameters of the two sets of Roots pumps the same? What is the layout like? Detailed information is needed for analysis.
For the Roots blower lion cooling system, check whether the inlet filter is clogged. Whether the oil has gone bad or is excessively high.

It mainly depends on the gaps between the rotors, as well as between the rotors and the casing. Also consider contacting the supplier.
