Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of Self-pressurizing agri constant-voltage equipment, comprises servomotor 1, reductor 2, ball screw assembly, 6, the oil cylinder 10 of exerting pressure, pressurized oil cylinder 14, pressure transducer 12.Adopting servomotor 1 is power source, and servomotor is fixing by screw and reductor 2, and the output shaft of reductor is connected with the screw mandrel 601 of ball screw assembly, 6, and reductor is bolted on top board 3 simultaneously; Top board 3 is fixed by the axis of guide 5 and nut with base plate 11.The oil cylinder 10 of exerting pressure is placed on base plate 11, and the piston end of the oil cylinder 10 of exerting pressure is connected by contiguous block 8 with the nut 602 of ball screw assembly, 6; Contiguous block 8 is fixed by screws on portable plate 7 with the nut 602 of ball screw assembly, 6; The oil cylinder 10 of exerting pressure is connected by connecting pipe 13 with pressurized oil cylinder 14, and the oil-out place of the oil cylinder 10 of exerting pressure is connected to pressure transducer 12; Pressurized oil cylinder 14 is placed on base plate, and push-down head 15 is connected with the piston end of pressurized oil cylinder 14 by screw, and seaming chuck 17 is connected with top board by screw, and sample chamber 16 is placed on the pallet 18 between seaming chuck and push-down head.
When the utility model work, servomotor 1 amplifies torque by reductor 2, drives the nut 602 of ball screw assembly, 6 to move up and down, and drives the piston movement of the oil cylinder 10 of exerting pressure, and makes oil in the to-and-fro movement between oil cylinder 10 and pressurized oil cylinder 14 of exerting pressure.In the time that oil flows to pressurized oil cylinder 14 from the oil cylinder 10 of exerting pressure by connecting pipe 13, the piston of pressurized oil cylinder upwards promotes push-down head 15, push-down head contacts with sample chamber, promoting sample chamber moves up and departs from pallet 18 again, contact with seaming chuck 17, seaming chuck and push-down head all extend in sample chamber, for sample is exerted pressure.In the time that oil is exerted pressure oil cylinder 10 from pressurized oil cylinder 14 by connecting pipe 13 flow directions, the piston of pressurized oil cylinder promotes downwards, push-down head and sample chamber move down gradually, until sample chamber falls back on pallet 18, push-down head and sample chamber disengage gradually, the pressure that now puts on sample chamber reduces gradually, for sample reduces pressure.The pressure of sample chamber and the pressure in oil cylinder 10 exits of exerting pressure have certain associated, can monitor pressure the feedback to the computer in oil cylinder 10 exits of exerting pressure by pressure transducer 12, and computer passes to servomotor 1 by signal and forms totally enclosed control pressurer system.Realize pressurization, the decompression of sample chamber or keep constant pressure.
