The first generation of pumping technology: electronically controlled commutation technology, PLC control solenoid valve commutation of pumping, S pipe replacement to the assigned post.
Machine assembly is simple, low production costs, but the electrical control complex, high failure rate and maintenance cost, easy to delay the progress of the project is the biggest drawbacks.
The second generation pumping technology: Ready mix concrete plant technique relies entirely on the master cylinder, hydraulic cylinder distribution of small changes in the signal to achieve action commutation.
1, concrete pumping, S pipe distribution without electrical components in PLC, lower failure rate, control is more reliable, greatly improved product life.
2, the entire hydraulic pump control technology, there is no constant pressure pump, the control box is not PLC, batch mixing plant, the tank is not close to the switch point, the structure is simple, maintenance costs are significantly reduced.
