DEVICE AND METHOD FOR CONTROLLING A TWO-CYLINDER THICK MATTER PUMP |
摘要 |
A liquid concrete pump has two cylinders and pistons alternately operated by a hydraulic reversing pump (6). For each pressure stroke the cylinders (50, 50') are connected to a delivery pipe (58) via a junction (56). The pump (6) and pipe junction (56) reverse direction at the end of each pressure stroke by a computer using information from a memory storage device and monitoring the time taken by each piston stroke. |
