摘 要
在當(dāng)今的船上,船舶制冷裝置是冷藏船、液化氣船、船舶伙食冷庫、冷藏集裝箱和船舶中央空調(diào)系統(tǒng)的核心設(shè)備。伴隨著海運業(yè)迅速發(fā)展和制冷、空調(diào)裝置的廣泛使用,在制冷裝置操作管理中正確分析、判斷并迅速排除故障已成為輪機管理人員的重要職責(zé)。制冷裝置各部件設(shè)計制造不妥,或操作管理不當(dāng)均可能造成相關(guān)運動部件和自控元件頻繁出現(xiàn)故障。故障一旦產(chǎn)生,船舶管理人員就應(yīng)及時分析故障誘發(fā)因素,并快速、準(zhǔn)確地找出故障源進而加以排除。因此,對船用制冷裝置的故障診斷與處理對輪機員來說是一項具有挑戰(zhàn)性的工作。此文分析了船舶制冷裝置的常見故障,并從設(shè)計和管理兩方面闡明了各種常見故障的診斷方法,并著重從船舶制冷操作管理角度提出了排除各種故障的相應(yīng)的對策。

ABSTRACT
In today's on board, ship cooling device is a refrigeration ships, liquefied gas vessels, ship food cold storage, refrigerated containers and ship the core of central air-conditioning system equipment. Along with the rapid development of the maritime industry and refrigeration, air-conditioning device widely used in refrigeration equipment in proper operation and management analysis, troubleshooting to determine and quickly has become an important engine management functions. Refrigeration equipment design and manufacture of various components is wrong, or the operation may be caused by mismanagement related to moving parts and frequent failure of self-control components. Fault once, ship managers should be timely analysis of fault-induced factors, and quickly and accurately identify the fault source to be excluded. Therefore, marine refrigeration equipment fault diagnosis and treatment of the engineer is a challenging task. This article analyzes the common ship refrigeration device failure, and from the design and management of two common failure to clarify a variety of diagnostic methods and focus on operations management from the perspective of the ship refrigeration has removed all kinds of faults corresponding countermeasures.
