YAJ-5000 microcomputer controlled electro-hydraulic servo compression and shear testing machine

☆.Applications and Characteristic:

●this series of products are used to test the mechanical strength characteristics of plate form neoprene pad,benzvalene form neoprene pad used in highway and bridge, it is a ideal COTS for high and bridge constructor, bridge neoprene pad manufacturer, the quality inspection organization to inspect highway and bridge constructing quality.

●this series of products possess the advantage of attractive appearance,high rigidity,excellent structure stability,easy of operation,high reliability and safety.

●this series of products are fully in line with the standards of(JT/T4-2004),(JT391-1999),(GB/T17988-2000).

●this series of products adopt multichannel digitally electro-hydraulic servo loading and control system, rubber pressing sample is placed on press table car, it is pushed into compressing and shearing station using hydraulic cylinder piston, the working piston placed in pedestal automatically control the loading procedure according to predetermined load,loading rate,keeping load time; horizontal electro-hydraulic servo loading system exerts horizontal load according test standards, there are load sensor and displacement equipped at piston rod head, which can real-timely and precisely measure and control load and displacement, the height of shear plate can be easily adjusted by motor; the vertical servo loading system equipped at press plate front-end exerts load upwards, at the same time measure turning angle.

●this series of products consist of main frame, shearing force stander,turning angle loading mechanism,mobile press table car,fore and after rail,three hydraulic-servo cylinders,hydraulic-servo oil source,electric control system,electric motor control system,high-precision displacement/deformation measuring and control computer system and related control software and so on.

●the main frame of this series of products adopts four-post construction, microcomputer based control mode, which can continuously and stably load, keep load, collect data, save data, draw curve, automatically print testing report. This series of products can do anti-compressing elasticity modulus test, anti-shearing elasticity modulus test, anti-shearing welding performance test, anti-shearing aging test, friction coefficient test, corner turning test, compressive ultimate strength test of bridge neoprene pad.

●there are internally installed two testing programs for plate form neoprene pad’s anti-compressing elasticity modulus test and anti-shearing elasticity modulus test, the two test can be accomplished automatically, printing report also can be accomplished automatically.

●actuator adopts American MOOG servalve (DDV series),its response precision and speed is  top-ranking

●this series of products equip with high capacity of forced cooling hydraulic source and brand industrial control computer, which can ensure the machine’s long time work with great load machine without fault.
