(Summary description)The main jacking pump station and the main jacking cylinder of the pipe jacking equipment are an indispensable part of the pipe jacking construction, which provides sufficient propulsion for the nose and the pipeline to advance. To realize the mutual integration work in the pipe jacking construction process, it is completely controlled by the operator of the pipe jacking machine in the pipe jacking machine console of the excavating pipe jacking machine. The console has a display screen to display the work progress of the drill bit. 1. The pumping station is controlled by a single pump to realize two different speeds of cylinder expansion and contraction. 2. In the construction of trenchless long-distance pipe jacking, the relay room assembly is placed at regular intervals to reduce the long-distance and large-tonnage jacking force in sections, and reduce the jacking force of the main jacking cylinder and the bearing force of the backrest of the working well. 3. The oil cylinder seals are sealed with high polyurethane, which has high pressure resistance, excellent wear resistance and good sealing performance. 4. The pumping station adopts the form of double pumps and double motors, with high pressure, large flow and convenient maintenance. 5. Multi-interface, and can realize linkage with the machine head.
