Technical field
The utility model belongs to a kind of hydraulic pressure installation, particularly a kind of servo vibrating hydraulic cylinder assembly of cylinder valve one.
Background technique
Servo vibrating hydraulic cylinder is made up of executive component (oil hydraulic cylinder), control unit (electrohydraulic control), Detecting element (displacement transducer and pressure transducer) usually.The control detection element by an intervening valve piece and executive component (oil hydraulic cylinder) indirect be connected one because many intervening valve pieces increase oil circuit, dynamic performance descends.The existence of intervening valve piece makes the leakage of oil point increase, and reliability reduces.Also increased simultaneously manufacture cost.
Summary of the invention
The purpose of this utility model provides a kind of servo vibrating hydraulic cylinder assembly of cylinder valve one, and it has good dynamic stability and response rapidity, and low cost of manufacture, reliability height.
For achieving the above object, the technical solution of the utility model is: the servo vibrating hydraulic cylinder assembly that designs a kind of cylinder valve one, which comprises at least electrohydraulic control 1, two pressure transducers 2 on electrohydraulic control 1 oil circuit are directly installed on the servo hydraulic cylinder 7, the two-piston of servo hydraulic cylinder 7 is back-to-back to be connected in the cylinder barrel of servo hydraulic cylinder 7, one on the two-piston bar of servo hydraulic cylinder 7 left, another to the right, displacement transducer 8 is connected on the interior right piston rod of servo-hydraulic cylinder body, left and right sides piston rod seals by sealing mechanism, it is characterized in that: servo hydraulic cylinder 7 two-piston chamber oilhole A, the output oil hole A of B and electrohydraulic control 1, B directly is communicated with by the oil hydraulic cylinder cylinder barrel; Pressure oil pipe interface P, return tube interface T and drain pipeline interface L are directly drawn by hydraulic cylinder 12, and and corresponding hydraulic pipe line be connected to form the oil hydraulic circuit of hydraulic servo proper functioning.
The left and right sides sealing mechanism of described servo hydraulic cylinder 7 comprises primary seal 6, secondary sealing 4, guide sleeve 5 and dust ring 3, and primary seal 6 and secondary sealing 4 are fixed on guide sleeve 5 both sides, and primary seal 6 is interior, secondary sealing 4 outside, dust ring 3 is fixed on secondary sealing 4 outsides.
The utility model has the advantages that: it is to make mechanical component according to given waveform signal, produces the hydraulic power unit of continuous shaking.Its control detection element (electrohydraulic control, displacement transducer and pressure transducer) directly is connected with executive component (servo hydraulic cylinder), has omitted the intervening valve piece, has shortened oil circuit length, has improved dynamic performance (stability of motion and rapidity).Adopt two-way ram bar structure.Displacement transducer and magnet ring are contained in the outside of oil hydraulic cylinder, the contact of discord fluid, and reliable performance, demolition and maintenance are (promptly do not take oil hydraulic cylinder apart, just can install and remove displacement transducer) easily.
Description of drawings
Below in conjunction with embodiment's accompanying drawing the utility model is described further.
Fig. 1 is the utility model example structure schematic representation;
Fig. 2 is the rear view of Fig. 1.
Among the figure: 1, electrohydraulic control; 2, pressure transducer; 3, dust ring; 4, secondary sealing; 5, guide sleeve; 6, primary seal; 7, servo hydraulic cylinder; 8, displacement transducer; 9, magnet ring; 10, piston rod; 11, flushing plate.
Embodiment
As depicted in figs. 1 and 2, two pressure transducers 2 on electrohydraulic control 1 and electrohydraulic control 1 oil circuit are directly installed on the servo hydraulic cylinder 7, the two-piston of servo hydraulic cylinder 7 is back-to-back in the cylinder barrel of servo hydraulic cylinder 7,10 1 on the two-piston bar of servo hydraulic cylinder 7 left, another to the right, left and right sides piston rod 10 seals by sealing mechanism, displacement transducer 8 and magnet ring 9 are contained on the interior right piston rod 10 of servo-hydraulic cylinder body, the contact of discord fluid, reliable performance, demolition and maintenance are (promptly do not take oil hydraulic cylinder apart, just can install and remove displacement transducer) easily.Overall structure is simply compact, has omitted the intervening valve piece, has reduced manufacture cost.This integrated structure has shortened the length of fluid passage simultaneously, helps improving the dynamic stiffness and the response rapidity of system.Adopt the structural type of double-action symmetrical hydraulic cylinder, helped increasing the dynamic stability of system.Output oil hole A, the B of servo hydraulic cylinder 7 two-piston chamber oilhole A, B and electrohydraulic control 1 directly are communicated with by the oil hydraulic cylinder cylinder barrel; Pressure oil pipe interface P, return tube interface T and drain pipeline interface L are directly drawn by hydraulic cylinder, and are connected with corresponding hydraulic pipe line, form the oil hydraulic circuit of Hydrauservo System proper functioning.
