The list:
Haining landmark high-rise 256 meters high, located next to the Cuckoo Lake, belongs to the super high-rise building. The construction height reaches 245, according to the requirements of a pump to the top, must choose high-power concrete. Xinrui Heavy Industry LP100.18.186D, this can meet a number of super high-rise projects, running well.
The main parameters are:
Concrete output: 100/55 m3/h concrete transport pressure: 9.7/18 MPa Distribution valve Form: S tube valve Concrete cylinder specifications (diameter × stroke) : Φ200×1800 Theoretical transport distance (vertical) : 320
Theoretical conveying distance (horizontal) : 1100 hopper size (capacity × loading height) : 600×1380 discharge port diameter DN150 Machine weight: 7360kg
Main features of concrete drag pump:
1) With high pressure small displacement, low pressure large displacement of two concrete conveying methods, the user can be based on the project to concrete conveying height (or distance) and displacement requirements reasonable choice.
2) The hydraulic system adopts imported famous brand original valve set to control the concrete pumping work, which greatly improves the reliability of the hydraulic system and greatly extends the life. Full hydraulic reversing, electrition-liquid proportional buffer system of open hydraulic circuit, reversing impact is small, less working oil link, (imported) valve group of good quality, small size, easy maintenance, the main oil pump using German Rextrox products, excellent performance, reliable work. In the working process, the main cylinder and the swing valve cylinder are reversed by the hydraulic system itself, so that the system is simpler and more reliable. The electro-hydraulic proportional buffer system is another innovation of Xinrui people's application of proportional control technology. The pressure sensor installed in the hydraulic system is used to monitor the reversing signal. When the controller receives the reversing signal monitored by the sensor, the whole hydraulic system is coordinated control immediately: First reduce the displacement of the main oil pump to low, and then the valve begins to reverse, and after the valve is finished, the displacement of the main oil pump is restored to large. In the whole reversing process, like the closed system, the displacement of the pump is from large to small to large, and the corresponding actuator also has the process of deceleration → stop → acceleration, and the reversing is also stable and impact-free like the closed system. It can be said that the hydraulic system of Xinrui's new series concrete conveying pump has the advantages of high hydraulic oil cleanliness, low temperature and long life of the open system, and the advantages of small reversing impact of the closed system. At the same time, the hydraulic components of the internationally renowned brands also provide a reliable guarantee for the high quality of the hydraulic system.
