1、工(gong)作人員必須掌握啟(qi)閉機(ji)的結構、性能與方(fang)法，并有一定的機(ji)械(xie)知(zhi)識，以確保(bao)機(ji)器的正(zheng)常(chang)運轉。

2、工作(zuo)前，對啟(qi)閉(bi)機進行(xing)檢查(cha)，每個部位潤(run)滑情況是否良好，螺(luo)栓有無松(song)動。電(dian)動啟(qi)閉(bi)時(shi)檢查(cha)電(dian)源線路是否接(jie)通，開關是否正常。

3、電動運轉時，工(gong)作人員不(bu)得(de)離開現場，發現問題(ti)立(li)即停機(ji)。

4、啟閉機維修時，必須除去(qu)載荷。

5、在使(shi)用(yong)時，需隨時由注(zhu)油(you)孔注(zhu)入潤滑油(you)，要(yao)經常保持(chi)足夠(gou)的潤滑油(you)，螺桿(gan)要(yao)定期清理油(you)垢(gou)，涂護新油(you)，以防銹蝕。

攔污柵(zha)，設在進水口前，用于攔阻水流挾帶的水草(cao)、漂木(mu)等(deng)雜(za)物(wu)（一般稱污物(wu)）的框柵(zha)式(shi)結(jie)構。 攔污柵(zha)由(you)(you)邊框、橫隔板和(he)柵(zha)條構(gou)成，支承在混凝土墩墻上，一般用(yong)(yong)鋼材制造。柵(zha)條間距(ju)視污物(wu)大(da)小、多(duo)少和(he)運用(yong)(yong)要求而定。水(shui)電(dian)站用(yong)(yong)的柵(zha)條間距(ju)取決于水(shui)輪(lun)機型號及尺(chi)寸，以保證通過(guo)攔污柵(zha)的污物(wu)不會卡在水(shui)輪(lun)機過(guo)流部件中為準。泄(xie)水(shui)隧洞和(he)泄(xie)水(shui)孔(kong)一般不設攔污柵(zha)，如洞徑或孔(kong)徑不大(da)，而沉木(mu)較(jiao)多(duo)需要設置時，柵(zha)條間距(ju)宜大(da)。攔污柵(zha)所受荷(he)載(zai)，除自重外，主要是污物(wu)堵塞后，在柵(zha)前后由(you)(you)于水(shui)位(wei)差形成的水(shui)荷(he)載(zai)，一般按(an) 2～4m水頭考慮。攔污柵(zha)的柵(zha)面尺寸決(jue)定于(yu)過柵(zha)流(liu)量和(he)允許過柵(zha)流(liu)速(su)。為減少水頭損(sun)失和(he)便于(yu)清(qing)污，一般要求過柵(zha)流(liu)速(su)不大于(yu)1.0m/s左(zuo)右(you)。攔污柵可以做成固定的(de)(de)或能夠起吊的(de)(de)。

攔污(wu)柵在平面(mian)上(shang)可以布置成直(zhi)線形(xing)或呈半(ban)圓(yuan)的(de)折(zhe)線形(xing)，在立面(mian)上(shang)可以是直(zhi)立的(de)或傾斜的(de)，依水(shui)流挾(xie)帶污(wu)物(wu)的(de)性質、多少、運用(yong)(yong)(yong)要(yao)求和清污(wu)方式(shi)決定。水(shui)頭較高的(de)壩(ba)后(hou)式(shi)水(shui)電站的(de)進水(shui)口常用(yong)(yong)(yong)直(zhi)立半(ban)圓(yuan)形(xing)；進水(shui)閘(zha)、水(shui)工(gong)隧洞、輸水(shui)管道多用(yong)(yong)(yong)直(zhi)線形(xing)。

深式(shi)進水口(kou)的(de)(de)攔污(wu)(wu)柵高度與水庫水位和清(qing)污(wu)(wu)方式(shi)有(you)關。對于不需要(yao)經常清(qing)污(wu)(wu)的(de)(de)，其(qi)頂部高程(cheng)可略高于防洪限制水位；需要(yao)經常清(qing)污(wu)(wu)的(de)(de)，則(ze)應(ying)高于需要(yao)清(qing)污(wu)(wu)的(de)(de)水位。高度較大(da)的(de)(de)攔污(wu)(wu)柵，可做成(cheng)幾節(jie)，每節(jie)的(de)(de)尺寸(cun)可根據起吊能力(li)確定。

污(wu)(wu)物清(qing)理可用(yong)人工或清(qing)污(wu)(wu)機。人工清(qing)污(wu)(wu)適用(yong)深度(du)較(jiao)淺(qian)，一般不超過(guo)5m。當攔污(wu)柵位于水下較深時，多用(yong)清(qing)污(wu)機清(qing)污(wu);必要時(shi)也可設置兩道攔污柵，需要清污時(shi),先將備用攔(lan)污(wu)(wu)柵(zha)(zha)放入檢修門(men)槽(cao)內，而后將工作攔(lan)污(wu)(wu)柵(zha)(zha)吊出進行清理。
