Zoomlion HBT80.16.174RSU bomba de hormigón estacionaria

ZOOMLION HBT80.16.174RSU 2018 【ACHIEVE】TOP CONDITION!!! Stationary concrete pump
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 3 / 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: Pumping output-pressure curve Low pressure pumping High pressure pumping Pumping pressure bar 4 / 14 Pumping output m /h ³
3.2.4 High reliability: Hydraulic components and electrical components are internationally famous brand products, coupled with excellent system design, so that the reliability of the pumping system is high, and the use of low cost.
3.3 Hydraulic system
3.3.1 Dual pump dual circuit hydraulic system The pump hydraulic system adopts the large displacement open or closed plunger pump and the main oil cylinder to form an independent pumping circuit. The distribution hydraulic system is composed of a high performance constant pressure pump and a distributing cylinder. The pumping oil circuit and the distribution oil circuit cooperate with each other and do not interfere with each other. The special flexible commutation technology makes the hydraulic impact smaller, and the system component has a longer service life. The double circuit design is easy to realize the logic control, the performance is reliable, and it is easy to update the update control function.
3.3.2 Fluid simulation design of hydraulic system Use fluid simulation software to simulate the hydraulic system. The various components of the hydraulic system reach the most reasonable match with the simulation, and optimizate the hydraulic system. 5 / 14
3.4 Electric control system
Outstanding feature of the electric control system is advanced in technology, simple operation, high reliability.
3.4.1 The IMF, German industrial controller, with the CAN or the Emerson, America brand programmable controller, as the control core, high reliability and powerful function; reduce the fault point, and improve the reliability of the electronic control system.
3.4.2 Electrical components using France Schneider, Panasonic and other imported components, to ensure the high reliability.
3.4.3 Wired remote control mode, and operate more convenient. 3.4.4 The electric control display screen monitors the real-time working condition, the fault alarm. The equipment operation monitoring, the maintenance and the maintenance operation is more convenient.
3.5 Cooling system The system circuit adopts a forced cooling device, and the working oil temperature is 70 degrees, to ensure the normal work. Water cooling system can be selected according to user requirements.
3.6 Power system
Assembly of Deutz (Dalian) BF6M1013 series engine, the electronic unit pump and external 6 / 14
exhaust gas recirculation technology, exhaust emission limits conform to the three phase of the national emission standards requirements. The real-time CAN line monitoring engine condition. the engine control unit (ECU) according to different conditions, can provide the best air-fuel ratio and the optimal ignition time to the engine, the engine power, economy and emission of the best. Intelligent diagnosis and emergency function to ensure timely troubleshooting and effective protection of the engine.
