To ensure the safety of coal mine production mine safety design is very important mine ventilation is one important ponent. The role of ventilation is to keep the various operating locations to the underground supply sufficient quantities of fresh air dilution and discharge of harmful toxic and radioactive gases and dust. Regulate air temperature and humidity underground so that it remains in the right state to the underground staff to create a good working environment for the continuous improvement of labor productivity. This design is base on the coal mine fluid machinery chooses type and design ,to plet three main task :coalmaster catchment equipment chosen design, ventilator bloser chosen design and 472 and G473 centrifugal fan vibration rdduction design. The last purpose is to improve the facility efficiency , reduce centrifugal fan vibration ,so we can carry out the biggest economic benefit. Annual production of 85 million tons this well borehole diameter of 4 meters air flow is 2362 m3/min gas concentration is low the initial negative pressure 1025Pa the late negative 1654Pa. After the air volume, the calculation of negative pressure drawing graphs select the fan to determine the fan operating conditions with different options than economic calculations and to determine the most suitable one of a group of programs verification of calculations. According to “Mine Safety Regulations ”and “Coal Industry Design Specification” under the relevant provisions of this design to safety economic supplement. Production in a safe environment how to do to minimize economic losses maximize energy use but also the design of this research. Key words: safety fan selection save energy 遼寧工程技術(shù)大學(xué)應(yīng)用技術(shù)學(xué)院畢業(yè)設(shè)計(jì)（論文）用紙 III 目錄 0前言 ................................................................................................. 1 1 離心式通風(fēng)機(jī) ................................................................................. 2 離心式通風(fēng)機(jī)的構(gòu)造和工作原理 ................................................. 2 離心式通風(fēng)機(jī)的性能參數(shù)及性能曲線 .......................................... 4 風(fēng)量 ........................................................................................... 4 風(fēng)壓 ........................................................................................... 5 功率 ........................................................................................... 6 效率 ........................................................................................... 6 轉(zhuǎn)速 ........................................................................................... 7 通風(fēng)機(jī)的性能曲線 ........................................................................ 9 離心風(fēng)機(jī)行業(yè)未來(lái)發(fā)展趨勢(shì) ......................................................... 9 本課題的研究目的和意義 ...........................................................10 2 礦山風(fēng)機(jī)設(shè)備的選型要求與原則 ...................................................12 礦山風(fēng)機(jī)設(shè)備的選型要求 ...........................................................12 礦山風(fēng)機(jī)設(shè)備的選型原則 ...........................................................12 選擇設(shè)計(jì)的任務(wù) ..........................................................................13 3 離心式通風(fēng)機(jī)的初步預(yù)算 ..............................................................15 設(shè)計(jì)參數(shù) ......................................................................................15 選擇風(fēng)機(jī)類型和型號(hào) ...................................................................15 估算通風(fēng)機(jī)必需產(chǎn)生的風(fēng)量 ....................................................15 估算通風(fēng)機(jī)的風(fēng)壓 ...................................................................15 對(duì)離心式通風(fēng)機(jī)類型的選擇 ....................................................16 4 472 型離心式 通風(fēng)機(jī)的選型計(jì)算 ...................................................17 離心式通風(fēng)機(jī)臺(tái)數(shù)的計(jì)算 ...........................................................17 確定通風(fēng)機(jī)工況點(diǎn) .......................................................................18 電動(dòng)機(jī)的選擇 ..............................................................................21 計(jì)算年電耗量 ..............................
