Though the graduation design,we should master the basic methods and steps of the of heating design and soon ,and improve the ability of settling problem ,going over information and planning the project on the national it bees the essentcal basic of design and practice in practical project after graduation. Graduation design is a general test of my theretical knowledge and practical learning during my fouryearcolledge study .through this plan ,it can shapen my understanding of all acquired knowledge and reinforce my ability that I settle the practical problems prehensively .therefore ,my subsequent job will rest on it ,a favourable basic. 5 摘要 本次畢業(yè)設(shè)計(jì)題目為 濰坊市 XX 花園 外網(wǎng)工程 設(shè)計(jì)。設(shè)計(jì)內(nèi)容包括熱網(wǎng)、給水、換熱站的設(shè)計(jì)負(fù)荷、流量計(jì)算、水力計(jì)算、管材及敷設(shè)方式的選擇，以及管道的保溫與防腐等。 根據(jù)中心城市供熱 區(qū) 間，小區(qū)周圍環(huán)境條件、小區(qū)內(nèi)部設(shè)施、投資情況定熱源位置。其次把所有采暖用戶分為兩個(gè)區(qū)，又已知的土建資料查閱手冊，計(jì)算每個(gè)區(qū)的負(fù)荷、流量，再采用經(jīng)濟(jì)比摩阻進(jìn)行水力計(jì)算，確定管徑。最后根據(jù)流量、揚(yáng)程選擇循環(huán)水泵和補(bǔ)給水泵，并繪制最不利環(huán)路水壓圖。 小區(qū)給水管道沿供熱管網(wǎng)敷設(shè)，并保證水質(zhì)、水量和 供 水時(shí)間的要求。 排水包括生活污水排水和雨 水排水兩部分。由于污水排水主要靠重力流，故沿原有地勢坡度敷設(shè)管線。雨水排水在保證不積水的情況下按地勢布置管線，但最遠(yuǎn)不應(yīng)大于 30 米設(shè)一個(gè)雨水 井。污水排水和雨水排水均在拐彎處設(shè)檢查井，以保證水流暢通。 關(guān)鍵詞： 熱網(wǎng)、給排水、換熱站 6 ABSTRACT This graduation project for WeiFang HONGJIHUAYUAN district. The title of the graduation design is the Thermal pipeline wateer supplying and drainage 、 water pump station 、 thermal exchange station of the district.
