高周波熱合機是基于高频电场的介质极化原理，其优点是加热均匀、粘着可靠、不存在碳化现象，是包装行业中常用的包装设备。高周波焊接机是高周波的常用叫法，又称高频机或高频波机，在使用高周波熱合機时，会出现各种问题，导致机器不能正常工作，那么如何解决这些常见的问题，希望能对您有所帮助。

高周波熱合機

高周波熱合機能熱合的材質：

首先確定該材料是否適合于高周波焊接(必須包含10%以上的PVC)，高周輸出銅皮連接是否正確(確定正常的高周輸出)，焊接時間和壓力設置是否合理(根據材料類型和厚度設置)；模具設計是否合理(確保壓力可以很好地傳遞到熔合表面)，溫度設置是否合理。這戲都會是導致熱合不了，熱合強度不牢的原因。

高周波熱合機的原因及故障排除：

1.打开电源，可以听到高频焊接机电源变压器的低频"嗡嗡"声，触摸自动微动开关，电磁阀可以吸收和关闭，打开电箱面板，发现电子管灯丝略红，测量电压低于正常电压，从"嗡嗡"声判断可能负载可能断路，高压整流电路中有两个高压整流硅颗粒击穿，用两个电压20 kV的硅颗粒，更换后可以正常工作，即排除故障。

2.高周热合机电源接通，电磁阀可以正常开关，但不能加热，测量整流电路是否正常，滤波电感是否正常，电子管灯丝亮度是否正常，如以上都没有问题，故障部分集中在电阻和电容振荡电路上，断电测量栅极电阻正常，如两个高压振荡电容器的测量中出现漏电现象，表明振荡状态被破坏，电容无法产生高频。更换电容后，高周波熱合機能正常运行，即故障排除。以上是我们对高周波熱合機不能加热的两种故障现象的调查和简要描述。

3.震蕩桶內的電子管燈開機不亮，請換管。

4.開高周波經常打火，用萬用表檢查發熱管是否漏電。

BETTOS, OR GROOMS, IN FULL DRESS. BETTOS, OR GROOMS, IN FULL DRESS. "Not that I am asking for sheer curiosity," she said gaily. "You see I am also in a position to throw a little light in a dark place. Do you know that the rest of the missing notes have been in my possession?" Evidently René Lalage passed as leader of them. They greeted him with shouts of approval and many strange manifestations of pleasure. One by one they produced tobacco and cigarette papers until the room was dim with smoke. Being by Being set; immovable, A funeral came pushing past me in the silence of this sleeping district: the body, wrapped in red, hung from a bamboo that rested on the bearers' shoulders. No one followed him, and the group disappeared at once in the deep gloom of the narrow alley. In that he was beaten by only a hundred feet. “No! Why should I?” The queen closed the session on the 9th of July, assuring the Parliament that her chief concern was for the preservation of our holy religion and the liberty of the subject—this liberty having been most grievously invaded by her through the Schism Bill. But the dissolution of her Ministry was also fast approaching. The hostility of Oxford and Bolingbroke was becoming intolerable, and paralysed all the proceedings of Government. As for Oxford, he felt himself going, and had not the boldness and[20] resolution to do what would ruin his rival. He coquetted with the Whigs—Cowper, Halifax, and others; he wrote to Marlborough, and did all but throw himself into the arms of the Opposition. Had he had the spirit to do that he might have been saved; but it was not in his nature. He might then have uncovered to the day the whole monstrous treason of Bolingbroke; but he had himself so far and so often, though never heartily or boldly, tampered with treason, that he dreaded Bolingbroke's retaliation. Bothmar, the Hanoverian envoy, saw clearly that Oxford was lost. He wrote home that there were numbers who would have assisted him to bring down his rival, but that he could not be assisted, because, according to the English maxim, he did not choose to assist himself. Swift endeavoured, but in vain, to reconcile his two jarring friends; and Oxford finally utterly lost himself by offending the great favourite, Lady Masham. He had been imprudent enough to oppose her wishes, and refuse her some matter of interest. He now was treated by her with such marked indignity, that Dr. Arbuthnot declared that he would no more have suffered what he had done than he would have sold himself to the galleys. Still, with his singular insensibility to insult, he used to dine at the same table with her frequently, and also in company with Bolingbroke, too. In Italy the French had been as unfortunate as they had been fortunate in Flanders. In November of 1746 the Austrians and Sardinians, assisted by a British fleet, had entered Provence and bombarded Antibes. They were recalled, however, by the news that the Genoese had revolted, and thrown off the Austrian yoke. In their retreat they were harassed by Marshal de Belleisle, laid siege to Genoa in vain, and began to quarrel amongst themselves. The French, to complete their own[113] discomfiture, marched another army into Italy under the brother of Belleisle; but they were stopped in the Pass of Exilles, and defeated, with the loss of four thousand men and of their commander, the Chevalier de Belleisle. "Why," whimpered Pete, "me and Sandy crept forward to a rock where we thought we could see better, and then we thought we could see better from another, and we kept a-goin' until we got clear up to where the limbers was, afore we knowed it. Just then a couple o' them powder-monkeys, as you call 'em, come runnin' back for cartridges, but they was both hit, and was all bloody, and both of 'em fell down and couldn't go no further, when they got the cartridges, though they wanted to. Me and Sandy thought it was too bad that the men up there at the guns shouldn't have no cartridges, when they was fighting so hard, so we picked up the boys' bags and run up to the cannon with 'em. The men there was so glad to git 'em, and told us to lay down our guns and run back for some more. They kept us goin' till the rebels was knocked out, and we thought we was doin' right and helpin', and they told us we was, and now you slap me. Boo-hoo-hoo!" "Dodd," Albin said, in what was almost a worried tone, "what the hell are you talking about?" Overhead there was a flash and a dull roar. Dodd stared before him at a tangled, smoking mass of blackness. A second before, it had been a fringe of forest. Smoke coiled round toward him and he turned and ran for the side of Building Three. There were other sounds behind him, screams, shouts.... It was not long before he had overtures from Captain MacKinnon. The Captain had expected an easy triumph; never since it became a free borough had Rye sent a Tory to Parliament. Now he was surprised and a little alarmed to see signs of definite Tory enterprise, banded under one of the most important and successful farmers in the district. It is true that he had the Bardons on his side, but the Bardons were too gentlemanly to be useful. He would have given much to corrupt Reuben, but Flightshot, which held the only bribe that could have made him so much as turn his head, insisted on keeping pure. He tried to hold his own by appealing to the fishermen and sailors against the agriculturists—but as these in the past had made little fortunes by smuggling grain, they joined the farmers in demanding a wheat-tax. "Most likely." There was a momentary pause after the baron had ceased. Holgrave hesitated to reply;—he had denied the charge, and he knew not what else to say. But when every eye except Calverley's, from Roland de Boteler's to that of the lowest freeman present, was fixed on the accused, expecting his answer, a slight movement was observed among the people, and Edith Holgrave, supported by Hartwell, pressed forward, and stood on the step by the side of her son. The gaze was now in an instant turned from the son to the mother, and Edith, after pausing a moment to collect her faculties, said, in a loud voice— HoME 一级爱免费资源福利在线ENTER NUMBET 002www.xzduofu.cn
