At the recent Bauma trade show, that was held in Munich, Germany, the hydrodemolition equipment manufacturer Conjet released a numbe rof novelties. Here is a summary.
Conjet Releases CWS620 Water Separation System
In many areas of the world, wastewater generated by hydrodemolition operations cannot be recycled into the sewage systems, due to high content of solid particles as well as too high pH-value. Conjet’s CWS620 takes care of this problem. Using two cyclones and injecting CO2 gas, the water is relieved of 97% of the solid particles while the pH-value is reduced from 12-13 to a set value of 7-10 (depending on local regulations and requirements). The CWS620 is equipped with a monitoring and control system that logs the pH-value over time and regulates the supply of CO2 gas. It also shuts off the sludge pump when water level is below a minimum set point. The monitoring system logs data which can be exported onto a removable media (USB) for later analysis. The treated water can be used to flush the demolished surface or recycled into the sewage system.
New Graphical User Interface for Conjet 7-Series Robots
Conjet AB releases a new Graphical User interface for all 7-series robots. The new interface is developed for work at a safe distance. Users operate the robot through the interface on the machine or on the remote-control box, as they are identical. The interface consists of two separate parts, one focused on operation and the other focused on service. The settings are easy to reach with just a push of a button. The interface also gives the operator instant feed back on the set parameter.
The display, located on the robot, is a 7-in (178-mm) Color Screen with a resolution of 800 x 480 px. One of the most important updates is that you maneuver between controls and options using a rotary encoder. The color display will be available on all Conjet 7-series robots. The Conjet Color Display remote control box is equipped with a 4.3-in (109-mm) LCD - 480 x 272 px color display with .08-in (2-mm) thick, protective Gorilla glass. It utilizes the surrounding light to give a sharp and clear image in more difficult environments (i.e. bright sunlight). The technology is developed to be power-saving.
“We have focused on simplicity as well as a steep learning curve during all phases of development. We want anybody to be able to understand how the robot works and how to use it, without compromising safety”, says Conny Tångring, Service Manager at Conjet. “A built-in guide shows the user how the robot is controlled and set up so that even inexperienced users can work safely.”
With the Conjet Color Display the user is able to steer and control every aspect of hydrodemolition at a safe distance. The operator doesn’t need to be close to the robot during operation. Should a fault arise, a comprehensive trouble shooting guide is presented to the operator. All existing robots in the 7-series can be equipped with the new interface.
Conjet AB Releases New High-Pressure Lance
Conjet AB releases a high-pressure lance and a wear resistant nozzle nut. Rated at 43,511 psi (3,000 bar) the lance can be used in single pump mode or in tandem mode connecting two pumps directly to the lance. It suits all robots in the 7-series as well as all earlier robots. The lance handles up to 37 gallons/min (140 litres/min) and can be fitted with ceramic nozzles. It can also be extended to suit different applications. The reinforced nozzle nut works with an exit hole of .2 in (5 mm). A carbon steel plate has been added to the nozzle nut tip to increase the operating life significantly.
Conjet Releases PTS (Parallel-to-Surface) Cutting Head
Conjet’s new parallel-to-surface (PTS) cutting head contains a variety of innovations to further improve reliability and the result from the hydrodemolition process. The PTS cutting head has been developed to house several improvements of the movement and control of the water jet. With the PTS, the nozzle is moved parallel to the surface when changing work direction. Absolute sensors, which eliminate the need for calibration, are now in place on both axes of the lance movement. A rugged mechanical design ensures smooth movement of the lance while maintaining total control of the lance.
With an angle of 45 degrees in both directions (left and right), cleaning behind rebars is easy. In combination with Variable Oscillation System (VOS) cutting concrete has never been easier. Rather than the old, time-consuming process of adjusting oscillation width, operators can make changes from the control panel, or as a set parameter for the cut. That means that uses can do a set number of overpasses with one width, and a different number passes with another width. As a result, the robot can expose rebars and cut much more accurately within a set parameter range. In addition, the PTS cutting head is equipped with quick couplings for hydraulic lines as well as a heavy-duty connector for the electric signals. This solution makes it very easy to extend or replace the hose package if needed.
