No matter what the machine is, there will be some parts that will be damaged after using it for a long time, so what are the parts that are easily damaged for Ace's rotary lobe pumps? Here Ace will tell you about them.
The parts of Ace's rotary lobe pumps that are susceptible to damage are as follows.
1. The pump casing is generally cast iron, which is prone to cracking under mechanical force or thermal stress. When the pump freezes during operation due to cavitation, or when the water accumulated in the pump casing is not released during winter, it is easy to rupture. If the damage is so severe that the pump casing cannot be repaired, it should be replaced with a new one.
2. Pump shafts are generally made of carbon steel, but they are easily damaged due to production quality, use or installation. Cracks, bends, worn journals, damaged threads, etc. may occur on the pump shaft, or fracture accidents may occur. If the damage is severe and beyond repair, replace the shaft with a new one.
3. The shaft tile of the plain bearing is made of copper-tin alloy, which has poor wear resistance and is one of the most easily worn and burnt out wearing parts. In general, the shaft tile can be repaired or replaced with a new one. Rolling bearings have an average service life of 5,000 hours, but are extremely susceptible to wear or damage due to improper installation, longer service life or poor maintenance. In addition to the individual parts of a rolling bearing that can be replaced with new parts, it is often necessary to replace the entire part.
4. The oil seal is a rubber product and is prone to wear and aging. Generally new ones have to be replaced.
Warm reminder: the above is the introduction of what is the easy to be damaged parts of the rotary lobe pump. We must pay attention to the easily damaged parts and replace them with new ones in time when they are damaged again.
