冰淇淋展示櫃不制冷的主要原因

來源:發布時間：2014/7/14 15:36:37

冰淇淋展示櫃和其他的冷藏展示櫃的制冷原理相同，冰淇淋展示櫃里都有温度控制器，对用户来说，简单地设定温度就可以了，不需要了解过多内部原理。冰淇淋展示櫃设定温度越低制冷时间就越长。冰淇淋展示櫃的制冷效果，和周围环境，柜体的密封性，开关冰淇淋展示櫃频率，壓縮機等因素有关。当冰淇淋展示櫃出现故障时，可能需要从以下几个方面来排查原因。
一、冰淇淋展示櫃壓縮機故障
　　壓縮機是制冷系统的核心部件，在冰淇淋展示櫃高强度长时间连续使用过程中，难免会出现问题。冰淇淋展示櫃不制冷有可能是壓縮機的过热保护器坏掉，但机组没有问题。更多可能是壓縮機被烧毁了。遇到这种情况，最好请专业人员仔细地检查壓縮機，针对问题解决壓縮機故障，该加制冷劑就要加制冷劑，该换就要换了。

二、制冷系統管道堵塞
　　如果抽真空时空气没有抽干净，或含有水分、造成冰堵。特别是有维修过的冰淇淋展示櫃，很容易出现管道堵塞。如果制冷系统内原始的清洁工作搞得不彻底，经过一段时间的运转，污垢在过滤器的铜网或毛细中，就会造成冰淇淋展示櫃管道堵塞。用耳朵贴近蒸发器也听不到任何气流声响，对出口处加温也不管用，这表明系统发生堵塞，应由专业技术人员排除。

三、管道泄漏
　　如果制冷管道穿孔泄漏，一定会造成冰淇淋展示櫃冷冻性能逐渐下降。先对制冷管道进行查漏．采用洗洁精查漏既经济又方便．将洗洁精涂抹在管道接口处以及壓縮機封口相接线性根部。对于管道泄漏，通常可能是腐蚀、焊接不良、碰坏管道几种原因。这些故障检测和修改都不难，但是需要由专业人员来处理。

　　冰淇淋柜不制冷常见的不制冷或制冷效果不好的原因是缺少制冷劑，通常加制冷劑就能解说。其他的比如控制电路问题，壓縮機热保护不运转，壓縮機坏，外机风扇不转，外机冷凝器太脏，管路堵塞等原因都可造成冰淇淋展示櫃不制冷，发现问题需要找专业人员来维修解决，没有制冷知识的非专业人员不能拆除维修。

Japanese children are well supplied with dolls and other playthings, and there are certain festivals in which the whole family devotes itself to the preparation or purchase of dolls to amuse the little ones. The greatest of these festivals is known as the "Hina Matsuri," or Feast of Dolls, hina meaning doll, and matsuri being applicable to any kind of feast. It occurs on the third day of the third month, and for several days before the appointed time the shops are filled with dolls just as they are filled among us at Christmas. In fact, the whole business in this line is transacted at this period, and at other times it is next to impossible to procure the things that are so abundant at the Matsuri. Every family that can afford the outlay buys a quantity of images made of wood or enamelled clay, and dressed to represent various imperial, noble, or mythological characters, either of the present time or of some former period in Japanese history. In this way the children are taught a good deal of history, and their delight at the receipt of their presents is quite equal to that of children in Christian lands. Not only dolls, but a great variety of other things, are given to the girls; for the Hina Matsuri is more particularly a festival for girls rather than for boys. The presents are arranged on tables, and there is general rejoicing in the household. Miniature tea and toilet sets, miniature bureaus and wardrobes, and miniature houses are among the things that fall to the lot of a Japanese girl at the time of the Hina Matsuri. This little island was in reality a prison, as its inhabitants were not allowed to go outside for any purpose, except once in three years, when a delegation of them made a journey to Yeddo to make presents to the Tycoon. They were compelled to travel the most of the way in closed norimons,[Pg 309] and thus their journey did not afford them many glimpses of the country. There is a tradition that they were required to go through the ceremony of trampling on the cross in the presence of the Tycoon, and also to intoxicate themselves, as a warning to the Japanese to shun the wicked ways of the foreigners. Whether either account be true I am unable to say; the assertion is very positively made and as positively denied, and therefore I will leave every reader, who has paid his money for the book, to make choice of the side of the story which suits him best. At noon they had gone twenty-five miles through a country which abounded in villages and gardens, and had a great many fields of wheat, millet, cotton, and other products of China; the fields were not unlike those they had seen on their voyage up the Yang-tse; and as for the villages, they were exactly alike, especially in the items of dirt and general repulsiveness. The modes of performing field labor were more interesting than the villages; the most of the fields were watered artificially, and the process of pumping water attracted the attention of the boys. An endless chain, with floats on it, was propelled through an inclined box by a couple of men who kept up a steady walk on a sort of treadmill. There were spokes in a horizontal shaft, and on the ends of the spokes there were little pieces of board, with just sufficient space for a man's foot to rest. The men walked on these spokes, and steadied themselves on a horizontal pole which was held between a couple of upright posts. Labor is so cheap in China that there is no occasion for employing steam or wind machinery; it was said that a pump coolie was able to earn from[Pg 359] five to ten cents a day in the season when the fields needed irrigation, and he had nothing to do at other times. "We'll stop now and say good-bye. We have seen China and Japan, and had a splendid time. We think we have learned a great deal about the two countries, and hope that what we have written about them has been interesting to those for whom it was intended. We have tried to see things, and think of them without partiality or prejudice. We believe that the people of the East have the same claims to respect that ours have, and that it is only a narrow mind that sneers at the ways of others because[Pg 421] they are not like its own. We know that there are many things in which we are superior to the Orientals, but we also know that we have our weak points, and might be profitably instructed by those whom some of us affect to despise. And the more we know these patient and industrious people, the more we shall be likely to respect them. We are soon to leave China, perhaps never to see it again; but both China and Japan will always be pleasant recollections to both "That was what the makers did for man," resumed the other. "Life had become impossible, and it was the only practical way out of the difficulty. You see, the makers were very clever, and very mild and gentle. They were quite different to ordinary human beings. To begin with, they were real." "'I saw how two to three hundred German soldiers, part of them slightly wounded, who were well able to walk, partly soldiers of the Landen garrison, who crowded about the open doors of one of the last wagons, raging and jeering against three seriously wounded British soldiers, about whom their French fellow-passengers told me that they had had nothing to eat for five days. The wounded were called "swine," were spit at, and some rifles were aimed at them. When I told a sergeant that it was a disgusting scene, he answered: "These British swine, they get paid for their filthy work." He alluded to the pay which the British volunteers receive because they enlist as mercenaries, Britain having no compulsory general military service. Before I witnessed this awful thing at Landen, Germans in the train had already told me that they simply killed any British whom they made prisoners. Others said that such a thing did not happen in their division, but one man contended that by his company already twenty-six had been killed. I did not believe them, and thought that they were better than they pretended to be. Plotinus is not only the greatest and most celebrated of the Neo-Platonists, he is also the first respecting whose opinions we have any authentic information, and therefore the one who for all practical purposes must be regarded as the founder of the school. What we know about his life is derived from a biography written by his disciple Porphyry. This is a rather foolish performance; but it possesses considerable interest, both on account of the information which it was intended to supply, and also as affording indirect evidence of the height to which superstition had risen during the third century of our era. Plotinus gave his friends to understand that he was born in Egypt about 205 A.D.; but so reluctant was he to mention any circumstance connected with his physical existence, that his race and parentage always remained a mystery. He showed somewhat more communicativeness in speaking of his274 mental history, and used to relate in after-life that at the age of twenty-eight he had felt strongly attracted to the study of philosophy, but remained utterly dissatisfied with what the most famous teachers of Alexandria had to tell him on the subject. At last he found in Ammonius Saccas the ideal sage for whom he had been seeking, and continued to attend his lectures for eleven years. At the end of that period, he joined an eastern expedition under the Emperor Gordian, for the purpose of making himself acquainted with the wisdom of the Persians and Indians, concerning which his curiosity seems to have been excited by Ammonius. But his hopes of further enlightenment in that quarter were not fulfilled. The campaign terminated disastrously; the emperor himself fell at the head of his troops in Mesopotamia, and Plotinus had great difficulty in escaping with his life to Antioch. Soon afterwards he settled in Rome, and remained there until near the end of his life, when ill-health obliged him to retire to a country seat in Campania, the property of a deceased friend, Zêthus. Here the philosopher died, in the sixty-sixth year of his age. “If the boat isn’t there when they bring up the seaplane, I’ll think you’ve hit the nail on the head,” Larry conceded. "It smells horribly," she exclaimed, dropping it on the floor, "it smells of hospitals—disinfectants." But she stooped and picked it up again. John Gay, a contemporary of Pope, Swift, and Arbuthnot, is now best known by his "Fables" and his "Beggar's Opera." His "Fables" have been extremely popular, and still make him a general name; but, in his own time, his "Beggar's Opera" was his great success. Its wit, its charming music, its popular characters, gave it a universal favour; and it is the only English opera that even to this time has become permanent. Gay's "Trivia; or, the Art of Walking the Streets of London," is still amusing, and some of his ballads have a lightness and buoyancy about them which justify the esteem in which he was held. "I belong to the 200th Ind." "Well, then," the old woman asked, "has anyone except myself understood them?" The head turned, the eyes raked the table. "Dr. Willis hasn't, or he wouldn't be sounding so hopeful. The rest of you haven't, or you wouldn't be talking about time. Rogier, you haven't, or you'd quit trying to pry and begin trying to prepare." He kicked Robert, and called up Richard to drive the cart over to Rye. "Wot else am I to do?" he exclaimed wretchedly; "'t?un't even as if I cud go on seeing you here. Oh, Bessie! I can't even t?ake you to the Fair on Thursday!" That evening he and his son had their first conflict. Pete announced that he had made arrangements with Ades for Albert's funeral, and Reuben announced with equal conviction that he was hemmed if Ades had any truck in it wotsumdever. Albert should be buried according to the rites and ceremonies of the Church of England, he wasn't going to have any salvation sung over his grave. Pete, on the other hand, stuck to his point, and alarmed Reuben with more religious phraseology. HoME 在线免费看成人人兽杂交aⅴENTER NUMBET 008www.shanghaiyjx.com.cn
