3.1.1 Intelligent control system

The first use of the industrial controller with self diagnosis and protection function make the machine more stable and reliable. Configuration of the touch screen, real-time monitoring of operating conditions, parameter settings, query historical data, view the fault records and maintenance skills. The cabinet switchs are configuraed all the features of the label, easy function expansion. The installation of stroke control and flexible reversing, the concrete cylinder stroke more in place, the suction is more strong, and the impact is less

3.1.2 Main technical highlights

Flexible reversing technique: Monitore the whole pumping conditions. Automaticly adjust the various mechanism to achieve smooth pumping of concrete without impact, improve the pumping efficiency, and extend the hydraulic parts’ and structural parts’ life.

Best time difference logic reversing technique: The main cylinder reversing and S valve change-over time is in the best state. The reversing impact is small, and the components’ life is longer.

Full stroke control technique: Ensure that the pumping cylinder piston stroke in place at the same time, to ensure that the concrete piston stroke in place, suction efficiency is higher; double signal control, higher reliability.

Engine start: According to the rotation speed and the starting time, the utility model can automatically close or cut off the starting circuit, and the operation is convenient. This can 4 / 14 effectively protect the starting motor of the diesel engine and prolong the service life of the diesel engine.

Adaptive variable power technology: Improve the pumping capacity. According to the concrete conditions and pumping conditions, so that the engine is always working at the best load rate, to ensure that it works in the economic fuel consumption area.

3.2 Pumping unit

3.2.1 Using the finite element analysis software, the strength and stiffness of the main components of the pumping unit under different working conditions are analyzed and calculated. At the same time, the fluid simulation of the concrete in the hopper and the concrete cylinder is carried out, and the pumping unit suction efficiency is higher than the industry average of 10%.

3.2.2The agitator mechanism adopts a new double lip sealing mode, which has the advantages of simple structure and long service life. The sealing shaft is provided with an alloy wear-resistant sleeve. The Zoomlion patent has a new agitator sealing structure and sealing agitator blade. The lower failure rate is now 0.3% from the original 7.6%, only 3.9% of the old structures; agitator blade appearance, low cost, long service life.

3.2.3 High technical performance: pumping system uses the large displacement pump oil. Not only improve the reliability of the equipment, but also better performance. Pumping curve is below:
