You Know What? What Are The Wearing Parts Of The Pump? What Should I Pay Attention To?
No.1
The pump shell is generally cast iron, which is prone to cracks due to mechanical force or thermal stress. When the pump in the work due to the impact of cavitation or in the winter did not release the water in the pump shell and frozen, it is also easy to break, such as heavy damage can not be repaired when the new pump shell should be replaced.
No.2
The pump shaft is generally carbon steel, but it is also easily damaged due to manufacturing quality, use or installation. The pump shaft may have cracks, bending, journal wear, thread damage, etc., and fracture accidents may also occur. If the damage is serious and cannot be repaired, a new shaft should be replaced.
No.3
The impeller is an important working part of the pump, which is made of cast iron (it can also be made of corresponding anti-corrosion material according to the working condition). It is also easy to damage due to manufacturing quality and use. The impeller may have cracks, holes or perforations formed on the surface due to cavitation, and the blade will be thinned or worn off for a long time, or even broken by debris. Some defects can be fixed; Some defects cannot be repaired, that is, a new impeller should be replaced.
No.4
The bearing bush of the plain bearing is cast of copper tin alloy, poor wear resistance, is one of the most easy to wear and burn out of the wearing parts, the bearing can generally be repaired, can also be replaced with new parts. Rolling bearings generally have an average service life of 5000 hours, but improper installation, long service time or poor maintenance, and easy to wear or destroy. In addition to the individual parts of the rolling bearings can be replaced with new ones, the overall parts are generally replaced.
No.5
The mouth ring is also known as the leakage or wear reduction ring, which is one of the most easily worn parts in the pump. It can be repaired or replaced after wear. When replacing the new leak reducing ring, its inner diameter should be configured according to the outer diameter of the impeller entrance. If the outer diameter of the impeller inlet is worn, it can be turned to eliminate grooves and ovals, and then configured with a leak-reducing ring with a reduced inner diameter. The outer diameter of the impeller inlet can generally be turned three times.
No.6
The filler will harden and lose elasticity after a long time, which will make the pump leak and leak, and generally replace the new filler.
No.7
The pump oil seal is a rubber product, easy to wear and aging, generally replaced with new parts.
