Targeted Zoomlion to create a new "southwest pump" (with photos)
Zoomlion made a new "Southwest Pump" In view of the special natural conditions in southwest China, concrete pumpability is very poor and so on, Zoomlion concrete machinery company recently tailored for the user a concrete pump - Southwest Pump HBT50 · 13 · 90SX, this pump will become Southwest pumping mechanism sand concrete "weapon." Due to the lack of river sand in southwest China, many projects can only replace sand with machine-made sand when mixing concrete. However, the mechanism of sand is made by mechanical crushing, of which more sharp corners, needle-shaped and weak particles more clay content. The concrete prepared with such a mechanism sand has poor water retention and fluidity and poor pumpability. As the leader of the domestic concrete machinery manufacturing industry, Zoomlion has always insisted on the concept of independent innovation and customer supremacy. In response to the particularity of concrete in Southwest China and the needs of users, it successfully developed this brand new concrete pump. Southwest pump HBT50 · 13 · 90SX In addition to inherit the advantages of the original joint pump performance, but also has the following new features: First, the delivery of a large amount. Theoretical side of the volume reached 69m3 / h, 50 pumps to achieve the square of the pump 70, giving the customer a great deal of benefits. Second, the country's first electric double hydraulic reversing circuit, both the electronic control system is simple, but also has the characteristics of liquid control and reliable to ensure that the S tube switch in place, the main cylinder and then retreat back to the head, the real realization A step by step, greatly reducing the probability of blocking tube. Third, using the main pump in turn for the pump, the distribution of pressure oil, the motor 92% of the power for the main pumping system, with a smaller power to get a larger pumping capacity. Fourth, the distribution of pressure intelligent automatic adjustment. Distribution system pressure according to the actual pumping resistance intelligent automatic stepless adjustment, not only to ensure adequate swinging torque, but also effectively prevent the swing impact. Fifth, the mixing system uses dual motor drive and spiral blades, increasing the stirring torque, the stirring shaft force more uniform and reasonable, and to ensure uniform flow of concrete in the hopper, which greatly improves the absorbency. At the same time, the use of a new mixing seal, which greatly improves the life of the stirring seal. Sixth, the use of new hanging pumping mechanism, the successful avoidance of eccentric wear of concrete piston, the concrete piston life of more than 15% higher than the ordinary pump.
