Do you know what are the vulnerable parts of water pumps?

Vulnerable parts are the fragile parts of water pumps that require special care during use, repair, and maintenance. So what are the vulnerable parts of a pump? What should I pay attention to?

No.1

Water pump casings are generally cast iron parts, which are prone to cracking under mechanical or thermal stress. When the water pump is affected by cavitation during operation or frozen due to not releasing the accumulated water in the pump casing during winter, it is also prone to rupture. If the damage is severe and cannot be repaired, the pump casing should be replaced with a new one.

No.2

The shaft of a water pump is usually made of carbon steel, but it is also prone to damage due to manufacturing quality, use, or installation reasons. The pump shaft may experience cracks, bending, journal wear, thread damage, etc., as well as fracture accidents. If the damage is severe and cannot be repaired, the shaft should be replaced with a new one.

No.3

The impeller is an important working component of a water pump, made of cast iron. Due to manufacturing quality and usage reasons, it is also prone to damage. Impellers may experience cracks, resulting in the formation of pits or perforations on the surface due to cavitation. Long term wear and tear can cause the blades to become thin or eccentric, and even be shattered by debris. Some defects can be repaired; Some defects cannot be repaired, so the impeller should be replaced with a new one.

No.4

The bearing shells of sliding bearings are made of copper tin alloy and have poor wear resistance. They are one of the easily worn and burnt out parts, and can generally be repaired or replaced with new parts. Rolling bearings generally have an average service life of 5000 hours, but they are easily worn or damaged due to improper installation, prolonged use, or poor maintenance. Rolling bearings, except for individual parts that can be replaced with new ones, generally require the replacement of the entire component.

No.5

The mouth ring, also known as a leak reducing or wear reducing ring, is one of the easily worn parts in water pumps. After wear and tear, it can be repaired or replaced with a new one. When replacing a new leakage reducing ring, its inner diameter should be configured according to the outer diameter of the impeller inlet. If the outer diameter of the impeller inlet is worn, it can be turned to eliminate grooves and ellipses, and then equipped with a reduced inner diameter leakage reducing ring. The outer diameter of the impeller inlet can generally be turned three times.

No.6

After prolonged use, the filler will become hard and lose its elasticity, causing air and water leakage in the water pump. Generally, a new filler should be replaced.

No.7

The water pump oil seal is a rubber product that is prone to wear and aging, and usually needs to be replaced with a new one.
