解析立柱间距的大小对于四柱液壓機的影响

四柱液壓機的立柱间距是一个关键参数，它决定了设备的整体刚性和稳定性。立柱间距的大小对于设备的性能和适用范围有着重要影响。

立柱间距较小时，四柱液壓機的剛性較強，能夠承受較大的壓力和變形量較小。這種情況下，設備適用于對成型精度要求較高的加工，如精密零件的壓制和成型。同時，較小的立柱間距也有利于提高設備的響應速度和減小能耗。

而立柱间距较大时，四柱液壓機的稳定性较好，能够适应较大的加工尺寸和重量。这种情况下，它适用于对成型尺寸要求较高的加工，如大型金属板材的折弯和成型。同时，较大的立柱间距有利于提高设备的行程范围，从而扩大其加工范围。

需要注意的是，立柱间距的选择还需要考虑其他参数的限制，如工作台尺寸、滑块行程等。在选择立柱间距时，需要综合考虑多种因素，以保障所选四柱液壓機既满足生产需求，又能发挥出良佳性能。

He turned slowly, as though considering whether to return and explain matters to the curate. "I must have frightened him," he whispered, almost audibly, "but I only wanted[Pg 104] to show him, and the parrot cage happened to be handy." "All right, darling," Hetty whispered. "Lie down and be quiet, and I will see what I can do for you. I shan't be long." She flew up the stairs headlong with that blind unreasoning terror upon her. A big clock suddenly striking two went off in her ears like a rifle shot. She caught a glimpse of her own face in a mirror. Was that white scared visage her own sunny, happy face? "Perhaps I have something to say to you," Hetty said between her teeth. "It must be done, surely, it must be done! That is her only chance of escape, and if she stops here she will be killed with the rest of us. Oh!... oh!..." The unhappy man asserted in a loud voice that183 he was innocent, but got the answer that he would have to prove that later on. But he never had a chance of doing that. Arriving at the market-place, he and three others were simply placed against the wall and shot. He could not even have spiritual assistance. Our two Princeton men had a beautiful time--at least they politely but I WON'T let myself think of anything but Latin Grammar. But he knew that she did not love him. She was grateful. It was sometimes an Apache trait. He realized that it was his curse and hers that he could not for an instant forget the strain. He read her character by it, half unconsciously. He saw it in her honesty, her sinewy grace, her features, her fearlessness, her kindness with children,—they were all Apache characteristics; and they were all repellent. From his youth on, he had associated the race with cruelty and every ghastly sight he had come upon, on the plains and in the mountains. It was a prejudice with more than the force of a heritage. He went on with his study of her, as she sat there. He was always studying her.[Pg 54] But he could not decide whether it was that she lacked sensitiveness and was really not greatly disturbed, or a savage sort of pride in concealing emotions. "Neither," answered Si. "It's only a common, straight, every-day march out into the country. You kin count upon one a day like this for the rest o' your natural lives—I mean your service. It's part o' what you enlisted for. And this's only a beginnin'. Some days you'll have to keep this up 15 or 18 hours at a stretch." That autumn Naomi entered on a time of black depression—an utter gloom and weariness of body and mind. It was no mere dull staggering under blows, merciful in its blindness and lack of acute feeling—it was a clear-eyed misery, in which every object was as distinct as it was dark, like one of those sudden clearings of a stormy landscape, when trees, hedges, meadows, loom under the frowning sky, outstanding and black in detail, more vivid than in sunshine. "Wished my farm wur in hell, dud he? He cursed my farm, dud he? The young whelp!" All was silence as the galleyman proceeded; labour had ceased, the evening repast was made, and many of the inhabitants of the village had already retired to rest. The evening was clear and cold, and the firmament was radiant with stars, the moon being only a few days old. By some strange impulse, the man who had so often gazed upon the far-spread beauty of an ocean sky, stood still for a moment here; and, by as strange a conceit, the silvery semicircle above, as it seemed, even in the crowd of lesser lights, brought to his mind the ever-smiling beauty of Lucy Hartwell. The wanderer lingered for a space—then hesitated—then turned suddenly—and, in less than five minutes, he had pushed open the hatch of old Hartwell's door and had entered boldly.
