What are the principles, performances and uses of the commonly used construction machinery equipment?
- 1.: concrete pump principle: concrete pump driven by motor pump system, the conveying capacity of constant power control of hydraulic system of concrete pump automatic control, manual control can also be used to select the concrete delivery volume. Performance: 1. using the hydraulic system of double pump double open circuit, the main pump valve swing circuit and S circuit are separate for fault diagnosis and removal; 2. pumping hydraulic circuit adopts the main valve pilot pressure control; 3. hydraulic system has safe relief protection, while the main pumping system overpressure, oil pump automatic pressure cutting off; 4. switching circuit with constant voltage supply with the energy storage device, so as to guarantee reliable swayingforce large and have the advantages of energy saving effect; 5. pumps and valves are used continuously, the world famous brand is more reasonable and more reliable and easily realized commodity concrete transport quantity adjustment; 6. hydraulic pipeline with cone seal pipe joint sealing material; 7. pumping circuit adopts a valve block mode of high and low voltage switch, convenient, no leakage; 8. with oil and oil filter technology, foreign body into the hydraulic system. Further improve the hydraulic system reliability and component life; 9. hydraulic hose hose. Use: widely used in commercial concrete demand for large, high grade and strict quality requirements, long conveying distance of high-rise buildings, municipal construction, electric power, energy, transportation and other civil and industrial buildings, especially the construction of the narrow space more show its true colour of a hero.s
