Pumpenwagen

The pump truck is developed on the basis of drawing on advanced domestic and foreign experience and using advanced modern computer simulation techniques to systematically analyze the effect of changes in various parameters like stress, displacement and natural frequency on the boom’s fatigue life. Meantime, we optimized the design of the hydraulic system, adopted the latest free fluid technique and greatly lessened the impact of pumping commutation on the distributing boom. In the boom structure optimization and the hydraulic system design. The yield strength of the plates exceeds 900Mpa, which ensures that the boom system has high strength and light weight. The boom system’s distributing pipe, landing legs, oil tank and so on have all received 100% stress-removing treatment after welding. Every welding seam has passed the 100% undamage and crack detection or X-ray radial check to avoid any tiny defects and to make the machine more enduring. Designed on the basis of accurate data from finite element analysis and dynamics simulation analysis, the boom system has a scientific structure and excellent performance. Besides, stress and strain tests are conducted by the national test center to verify the agreement between the calculation and analysis result of the boom structure and its actual working condition. The design of Pump Truck adopts an international purchase strategy, and all its key components are world-famous brands. ·Imported German STEIBEL transfer case and the German Rexroth pumps; ·Original imported slewing gear and the rotary motor; ·The proportion of imported German Harvey Multi-way valve; ·Imported Germany Rexroth and Italian oil companies control valve; ·All components of the electric control box imports, PLC and other control modules are Siemens products. Features of hydraulic system: Formed by the confluence of two-pump hydraulic drive system for the free flow of closed, high output power loss, no impact to the stable. No red tape in the middle of changing the control valve block, to reduce the impact of change to avoid the heating oil temperature too high.
