The burning of large Roots vacuum pumps can be caused by several factors:
- Leakage: Roots vacuum pumps are immersed in water, so leaks can lead to combustion.
- Cable breakage and damage: Cable breakage and damage can cause electric shock accidents and also put the Roots vacuum pump unit in a two-phase working condition while running, making it neither waterlogged nor easy to damage the motor.
- Low power supply voltage or frequency.
- Rotor blockage: When the rotor is blocked, the stator winding produces a blocking current that is 5-7 times the normal full-load current. If not protected, the vacuum unit will burn up soon. Reasons for rotor jamming may include impeller jamming, debris from the mechanical seal stuck on the shaft, or dirt winding.
- Wear and corrosion: Wear greatly reduces the performance, flow, head, and efficiency of the vacuum unit. The impeller and pump cover may rust, causing the rotor to seize.
Extend the service life of Roots vacuum pump
To ensure a longer service life for the high-speed screw pump, the following measures can be taken:
- Maintain a reasonable operating speed: A speed regulator or deceleration mechanism can be employed to decrease the operating speed.
- Keep the product clean
- Regular maintenance
- Regular oil replacement:When operating a Roots vacuum pump, one should observe the changes in oil level, pay attention to replacing relevant parts, and replace the oil in a timely manner.
