          During the conveying process of the concrete pump, as the pumping pressure increases, the pumping impact force will force the pipe to move back and forth, which not only loses the pumping pressure, but also causes the connection between the pump pipes to be under impact and intermittent tension. The state of the pump can cause premature damage to the pipe clamp and rubber ring and overflow of the cement slurry. Therefore, the pump must be fixed.
