1. Pump pipe: a set of good quality wear-resistant pipe, the service life is generally about 30,000 cubic meters of concrete, that is to say, it must be replaced after 30,000 cubic meters of concrete is hit. Therefore, according to the annual pumping of 100,000 cubic meters of concrete machinery, at least 3 sets of pump pipes must be replaced a year.
The cost of replacing a complete set of original pump pipes for a 52-meter pump truck
is about USD4700. Therefore, the annual replacement cost of the pump pipes is USD14000, which is close to USD14700.
2. Spectacle panels and cutting rings: The service life of the original spectacle panels and cutting rings is about 30,000 cubic meters of concrete, so three sets need to be replaced a year. The price of a set of original spectacle plates and cutting rings is around USD700, so the annual cost is USD2000.
3. Piston: The service life of the piston is the shortest, and a set of piston needs to be replaced for about 15,000 square meters. The price of a set of original pistons is around USD180, so 7 sets need to be replaced a year, and the annual cost is USD1300.
4. Stirring system: The mixing system contains a lot of wearing parts, such as stirring half shaft, wear-resistant sleeve, bearing, seal, etc. The price of a set of wearing parts of the original mixing system is about USD200. If the lubrication is done well, the service life is about 20,000 cubic meters of concrete, and the annual cost is USD1100.
