YAW-3000A computer controlled servo pressure testing machine

one . Function and Structure Description

⊙ YAW-3000A Computer controlled servo pressure testing machine is mainly used for compression test a variety of materials, such as: compressive strength test of cement, concrete and various building bricks, rubber, concrete structures, metal structures and the like.

⊙ The tester machine mainly by the host, servo oil source, control cabinet and computer printers and other components. Adopts hydraulic loading, oil pressure sensor measuring, electro-hydraulic servo control system to automatically control the test process, the computer screen displays the test data and curve , for data processing, storage and printing.

⊙ The oil cylinder mounted under the beam mobile host, mobile beam can be adjusted within a certain range test space. Host part of the main beams supported by two screws on the base by the beam, screw, table, car four parts., be constituted by a nut fastening the loading frame; fitted with spherical seat on the beam, the pressure plate mounted in a spherical seat, loading time can be automatically adjusted according to the direction of the shape of the specimen, so that the specimen even by force; adjust the motor mounted on the beam , driven by the motor worm, worm drives worm gear, driven by the worm wheel nut and then rotate nut drive beam moves up and down to adjust the test space; in the spring-loaded beams, support from the weight of the beam, eliminate threaded nut and screw Thread gap in the vertical direction, the test reliable, accurate data; cylinder and piston is the main part of the host, their contact surface after the precision machining, to maintain a certain fit clearance and proper film, when high-pressure oil pump sent After entering the cylinder, holding the piston together with the car, under rising pressure plate, etc., so that the load is gradually applied to the sample; lower platen mounted in a small car, the car can be moved back and forth on a track, handling specimens can push the car.

⊙ Load adaptive hydraulic schematic meter-governing system hydraulic oil tank through the motor-driven gear pump into the high pressure oil passage, through the check valve, high-precision high pressure filter, pressure valve, servo valve , into the cylinder. computer sends a control signal to the servo valve, control and direction of the opening of the servo valve to control the flow into the cylinder to achieve constant test force control, the relative displacement and the like.
