Roots pump failure analysis and solution

In recent years, the Roots pump has been developed very fast and has been widely used in many fields such as smelting, petroleum, electronics, chemical, electrician, agriculture and industry. Such products have the advantages of fast start-up, less power consumption and low maintenance cost, the use intensity of Roots pumps is increasing, the problems related to Roots pump failure analysis and troubleshooting, and other related issues have also been heatedly discussed by all walks of life. That Roots pump failure may be what? What are the solutions to these failures? Roots pump failure analysis and solutions Failure phenomenon One: the ultimate pressure failure Failure analysis: 1. Piping, the system leaks; 2. Pre-pump limit pressure drop; 3. Lubricants dirty or model is wrong; 4. Seal Wear and tear; Solution: 1. System Leakage; 2. Overhaul or replacement pump; 3. Exchange of lubricants; 4. Exchanging the seal; Failure phenomenon II: pumping speed failure Analysis: 1. Pipe ventilation capacity is not enough; Pre-pump pumping speed down; Solution: 1. Increase the ventilation capacity of the pipeline; 2. Overhaul or replacement of forepump; Fault phenomenon three: motor overload Failure Analysis: 1. Population pressure is too high; Single-sided contact; 3 front pump back to the Roots pump oil; solution: 1.Expand the front pump exhaust time to reach the inlet pressure; 2 adjust the rotor face clearance; 3 anti-oil return device; Of the three failures is the Roots pump more common phenomenon in the work process, I am fortunate in the work experience of workers, these fault solutions have been well implemented and preserved. However, Roots pump work, it may not only the failure of these problems, when encountered problems, or users need to be based on actual problems to be addressed.
