1、在使用前對進(jin)出水(shui)管(guan)道、水(shui)池進(jin)行(xing)全面(mian)沖洗，清除塔(ta)(ta)(ta)內垃圾，以防管(guan)路堵塞。2、各(ge)部(bu)件(jian)連(lian)接(jie)螺栓，特(te)別是傳(chuan)動(dong)部(bu)件(jian)風(feng)(feng)機(ji)，電機(ji)，旋轉布水(shui)器(qi)，必須(xu)一(yi)一(yi)擰(ning)緊。3、檢(jian)(jian)查(cha)齒輪減速器(qi)油(you)位是否正常，皮(pi)帶減速器(qi)的(de)皮(pi)帶運行(xing)約60H后(hou)，須(xu)重新檢(jian)(jian)查(cha)皮(pi)帶拉力，確保正常，并加(jia)注(zhu)(zhu)黃(huang)油(you)一(yi)般每臺50克左右，三個月(yue)檢(jian)(jian)查(cha)加(jia)注(zhu)(zhu)一(yi)次。4、風(feng)(feng)葉轉動(dong)靈活，無磕碰上(shang)殼體。當風(feng)(feng)機(ji)工作(zuo)時(shi)，從塔(ta)(ta)(ta)頂往下看(kan)應(ying)(ying)為(wei)順時(shi)針，向上(shang)抽風(feng)(feng)。5、冷(leng)卻(que)(que)塔(ta)(ta)(ta)如有(you)異常聲(sheng)音(yin)應(ying)(ying)立即停機(ji)，全面(mian)檢(jian)(jian)查(cha)，直至排除故障。6、風(feng)(feng)機(ji)工作(zuo)后(hou)，打開水(shui)閥，同時(shi)水(shui)泵流量、進(jin)塔(ta)(ta)(ta)水(shui)壓、電流、電壓、振動(dong)、噪音(yin)值均應(ying)(ying)在規定范圍內，并做好有(you)關冷(leng)卻(que)(que)塔(ta)(ta)(ta)的(de)進(jin)出水(shui)溫度，流量，氣象參數(shu)的(de)記錄。7、發現布水(shui)器(qi)不轉或(huo)布水(shui)不均勻(yun)時(shi)，應(ying)(ying)停機(ji)檢(jian)(jian)修。8、循環水(shui)應(ying)(ying)為(wei)自來水(shui)或(huo)清潔水(shui)，不宜含油(you)污和雜質，渾濁度不大(da)于50mm1。9、冷(leng)卻(que)(que)塔(ta)(ta)(ta)作(zuo)為(wei)重要的(de)冷(leng)卻(que)(que)設備，應(ying)(ying)有(you)專人負責管(guan)理，北方天氣較冷(leng)要考慮結(jie)冰影響。
