廠家怎樣選擇卷揚啟閉機製動器
1、在每台啟閉機獨立的驅動機構中，必須分別設置製動器。在啟閉閘門時，製動器是用來調節閘門的下降速度、zhidonghezantingdezhidongzhuangzhi，zaiqibijigouzhong，zhidongqiyonglaixishouyundongzhongdeguanxing，shiqizaiyidingdezhidongjulineitingzhixingzou。qibijidezhidongqizhongleihenduo，yibangenjuzhidonglijujishiyongqingkuanglaixuanze，zhidonglijubudashi，kexuanyongduanchongchengjiaoliuzhidongqihuochangchongchengjiaoliuzhidongqi，zhidonglijudayongchangchongcheng（或雙短衝程）交流製動器。

3、應(ying)充(chong)分(fen)注(zhu)意(yi)製(zhi)動(dong)器(qi)的(de)任(ren)務(wu)。例(li)如(ru)支(zhi)持(chi)物(wu)品(pin)製(zhi)動(dong)器(qi)的(de)製(zhi)動(dong)轉(zhuan)矩(ju)必(bi)須(xu)有(you)足(zu)夠(gou)的(de)裕(yu)度(du)，即(ji)應(ying)保(bao)證(zheng)一(yi)定(ding)的(de)安(an)全(quan)係(xi)數(shu)。對(dui)於(yu)安(an)全(quan)性(xing)有(you)高(gao)度(du)要(yao)求(qiu)的(de)機(ji)構(gou)，需(xu)裝(zhuang)設(she)雙(shuang)重(zhong)製(zhi)動(dong)器(qi)，如(ru)運(yun)送(song)熔(rong)化(hua)金(jin)屬(shu)或(huo)易(yi)燃(ran)、爆bao炸zha物wu品pin的de起qi升sheng機ji構gou，規gui定ding必bi須xu裝zhuang設she兩liang個ge製zhi動dong器qi，其qi中zhong每mei一yi個ge製zhi動dong器qi都dou應ying能neng單dan獨du安an全quan地di支zhi持chi鐵tie水shui包bao等deng運yun送song物wu品pin，而er不bu致zhi墜zhui落luo。又you如ru礦kuang井jing提ti升sheng機ji，除chu在zai高gao速su軸zhou上shang設she蘭lan製zhi動dong器qi外wai，還hai在zai卷juan筒tong或huo繩sheng輪lun軸zhou上shang設she置zhi製zhi動dong器qi，對dui於yu重zhong物wu下xia降jiang製zhi動dong(即滑摩式製動)則應考慮散熱問題，必須有足夠的散熱麵積，使其能將製動時重物位能所產生的熱量散去，以免過熱使製動失效。
4、應考慮應用的場所。例如安裝製動器的地點有足夠的空問時，則可選用外抱式製動器，空間受限製處，則可采用內蹄式、帶式或盤式製動器。根據製動器在不同設備中的性能運用，來選擇合適的型號，使我們所必須了解的內容。
