1íóHost machine is with double column type, which make the conformation compact and arrangement reasonable. 2íóAdopt precise electro-hydraulic servo proportional valve. The speed is fast and the controlling accuracy is high. 3íóMechanic limit pistons protection assures the safety of testing. 4íóSetup overload protection which acn stop automatically,when the load exceeds the maximum by 2-5%. ó=íóControlling system This machine is with digital and multi-channel loop of measuring and controlling system. It adopts force closed loop control technique and has the function of constant stress loading and load keeping. Loading speed can be arbitrarily set and the testing curves can be real time displayed. Characteristics of softwareú¦ 1íóThe software integrate bending resistant test and compression resistant test procedure , such as bricks, cement, concrete and mortar. 2íóThe software divide testing procedure as follows: tile compression resistant executive program(GB13544í¬2000), cement compression resistant testing program (GB17671í¬1999), concrete specimen testing program(GB/T5001í¬2002)and mortar testing program(GB170í¬90). 3íóThere is no subsection in all process. (Or classify according to the requirements of customers.) 4íóComplete test in batch automatically and adjust breaking of specimen. 5íóWindows Style can be controlled by human or computer.It is easy to manage and control,collect and calculate. 6íóRecord and save testing datas automatically.
