Cleaning Concrete Pump Can Prolong the Service Life
After the pumping of concrete pump, it is necessary to clean the hopper and delivery pipeline system.Therefore, the pumping and cleaning of concrete pump is closely connected with the performance of concrete. The cleaning of concrete pump can be classified into cleaning with water and cleaning without water. The cleaning without water is composed of cleaning with compressed air and cleaning with ball plugged into hose. And the cleaning with water can be divided into cleaning with ball plugged into the outlet elbow, cleaning with ball plugged into concrete cylinder and cleaning without ball.
It is common to see that there is often some concrete remaining in the concrete cylinder. After pumping, if users don’t eliminate the remaining concrete timely, the solidification of concrete will inevitable.When the piston runs again, the sealing surface of piston will be direct under the impact of the solidified concrete inside the concrete cylinder and parts of piston sill be peeled off. This kind of damage is quite different from the normal abrasion of the piston seal. The sealing surface of piston can not compensate by itself under the pressure, which can lead to mortar leakage and suction phenomenon. As a result, the mini concrete pump will be unable to pump and the delivery pipeline will be blocked.
