Description
Technical field
The present invention relates to a kind of impingement type hydraulic generator speed control device, particularly a kind of oil cylinder.
Background technique
Traditional impingement type hydraulic generator speed governing relies on closing gate size and water level difference of height to control substantially, complex operation, and in addition, hydraulic loss is large, and water resource waste is serious, and efficiency is low.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provides a kind of simple to operate, regulates accurately and the oil cylinder of water saving.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of oil cylinder, comprise the outer cylinder body and inner cylinder body that are connected by least one landing nipple, described inner cylinder body comprises cylinder barrel, front capping and rear seal-cover, the described outer cylinder body side corresponding with front capping is provided with the opening of taper, this open outer side is fixedly connected with jet pipe, described front capping extenal fixation is connected with coaxial conical head, and this conical head can pass from the opening of outer cylinder body and energy shutoff jet pipe; Be provided with coaxial piston and piston rod in described inner cylinder body, and be sleeved on the spring outside piston rod, one end of piston rod passes from piston, passes and be connected with conical head in the other end the past capping of piston rod.
One end arranged outside that described piston rod is connected with piston has magnet ring, central axis place is provided with endoporus, described rear seal-cover is provided with displacement transducer, this displacement transducer one end is connected with the guide rod of built-in electric wire, the other end of this guide rod through magnet ring and endoporus, and can move forward and backward in endoporus.
Be set with balance set outside piston rod between described front capping and spring, between described spring and balance set, be provided with spring seat.
After the present invention adopts said structure, press water is filled with between above-mentioned outer cylinder body and inner cylinder body, when needs reduce water speed, only need to oil-filled pressurization in the cavity of inner cylinder body piston-rodless, promotion piston rod moves forward by piston, piston rod moving belt moves conical head and moves forward shutoff jet pipe, thus reduces the flow velocity of water; When needs increase water speed, release of draining the oil in the cavity of inner cylinder body piston-rodless, conical head, under the drive of spring, slowly will leave jet pipe, thus increases water speed.Upper displacement sensors can the shift value of accurate measurements piston rod, thus regulates the flow velocity of water more accurately.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of oil cylinder of the present invention.
Wherein have: 1. outer cylinder body; 2. inner cylinder body; 3. landing nipple; 4. jet pipe; 5. capping before; 6. cylinder barrel; 7. rear seal-cover; 8. piston; 9. piston rod; 10. spring; 11. conical heads; 12. magnet rings; 13. displacement transducers; 14. guide rods; 15. endoporus; 16. balance sets.
Embodiment
Below in conjunction with accompanying drawing and concrete better embodiment, the present invention is further detailed explanation.
As shown in Figure 1, a kind of oil cylinder, comprise the outer cylinder body 1 and inner cylinder body 2 that are connected by least one landing nipple 3, described inner cylinder body 2 comprises cylinder barrel 6, front capping 5 and rear seal-cover 7, described outer cylinder body 1 side corresponding with front capping 5 is provided with the opening of taper, this open outer side is fixedly connected with jet pipe 4, and described front capping 5 extenal fixation is connected with coaxial conical head 11, and this conical head 11 can pass from the opening of outer cylinder body 1 and energy shutoff jet pipe 4; Coaxial piston 8 and piston rod 9 is provided with in described inner cylinder body 2, and the spring 10 be sleeved on outside piston rod 9, the two ends of this spring 10 are provided with spring seat, one end of piston rod 9 passes from piston 8, pass in the other end the past capping 5 of piston rod 9 and be connected with conical head 11, preferably removably connecting, according to the internal diameter size of jet pipe 4, change conical head 11 corresponding thereto, thus make oil cylinder of the present invention can adapt to the jet pipe 4 of different inner diameters size.
One end arranged outside that described piston rod 9 is connected with piston 8 has magnet ring 12, central axis place is provided with endoporus 15, described rear seal-cover 7 is provided with displacement transducer 13, this displacement transducer 13 one end is connected with the guide rod 14 of built-in electric wire, the other end of this guide rod 14 through magnet ring 12 and endoporus 15, and can move forward and backward in endoporus 15.
Upper displacement sensors 13 monitors the movable shift value of piston rod 9 by the misalignment of reaction magnetic ring 12, can regulate current size as required, set corresponding shift value, can control the speed of current exactly.
Piston rod 9 between the spring seat of capping 5 before described vicinity and front capping 5 is also set with balance set 16.This balance base 16 can prevent moving radially of piston rod 9 or shake, and makes this cylinder efficient more stable and reliable.
During use, press water is full of between above-mentioned outer cylinder body 1 and inner cylinder body 2, when needs reduce water speed, flow velocity as required, set the shift value of piston rod 9, in the cavity of backward inner cylinder body 2 piston-rodless 9, oil-filled pressurization (does not mark oil filler pipe in figure, for prior art), promotion piston rod 9 moves forward by piston 8, and spring 10 compresses, and drive conical head 11 moves forward and slow shutoff jet pipe 4 by the movement of piston rod 9, when piston rod 9 displacement reaches setting value, by feedback signal, stop oil-filled pressurization, thus reduce and keep the flow velocity of water; When needs increase water speed, flow velocity equally as required, set the shift value of piston rod 9, release of draining the oil in the cavity of inner cylinder body 2 piston-rodless 9, spring 10 slowly resets, conical head 11 is under the drive of spring 10, to slowly leave jet pipe 4, when reaching setting shift value, by feedback signal, stop draining the oil release, thus increase and keep water speed.Aforesaid operations is simple, and accurately, the utilization ratio of water is high, avoids the waste of water.
