關於液壓係統的原理分析及主要設計要點

 

    液壓起重係統的穩定型設計

 

    在zai液ye壓ya係xi統tong的de啟qi動dong升sheng起qi的de過guo程cheng中zhong一yi般ban情qing況kuang下xia是shi通tong過guo采cai取qu調tiao節jie液ye壓ya泵beng和he換huan向xiang按an鈕niu來lai實shi現xian調tiao速su的de這zhe樣yang既ji能neng保bao證zheng液ye壓ya機ji的de正zheng常chang工gong作zuo又you不bu會hui出chu現xian意yi外wai狀zhuang況kuang。此ci種zhong調tiao速su法fa既ji簡jian單dan又you可ke靠kao，調tiao速su範fan圍wei較jiao大da，調tiao速su平ping穩wen無wu極ji，也ye可ke實shi現xian起qi升sheng機ji構gou工gong作zuo速su度du的de微wei調tiao。

 

    為wei了le在zai實shi際ji操cao作zuo中zhong穩wen定ding液ye壓ya係xi統tong的de性xing能neng
，合he理li的de進jin行xing工gong作zuo，往wang往wang在zai傳chuan送song過guo程cheng中zhong對dui液ye壓ya機ji器qi的de馬ma達da供gong油you係xi統tong進jin行xing適shi應ying的de調tiao節jie。當dang起qi重zhong係xi統tong的de升sheng起qi幅fu度du比bi較jiao大da時shi就jiu要yao運yun用yong到dao馬ma達da減jian速su功gong能neng來lai進jin行xing適shi當dang的de調tiao節jie
，一yi般ban來lai說shuo實shi際ji的de操cao作zuo過guo程cheng中zhong還hai會hui運yun用yong到dao重zhong力li下xia降jiang裝zhuang置zhi，也ye就jiu是shi說shuo在zai即ji在zai起qi升sheng卷juan筒tong與yu傳chuan動dong軸zhou間jian裝zhuang有you離li合he器qi，有you液ye壓ya係xi統tong保bao證zheng空kong鉤gou和he載zai荷he的de重zhong力li下xia降jiang時shi

，打da開kai離li合he器qi及ji製zhi動dong器qi使shi起qi升sheng卷juan筒tong與yu液ye壓ya馬ma達da脫tuo開kai自zi由you轉zhuan動dong，則ze空kong鉤gou或huo重zhong物wu在zai重zhong力li作zuo用yong下xia
，以yi較jiao高gao的de速su度du下xia降jiang。

 

    液ye壓ya傳chuan動dong由you起qi升sheng機ji構gou
，回hui轉zhuan機ji構gou
，變bian幅fu機ji構gou，伸shen縮suo機ji構gou和he支zhi腿tui部bu分fen等deng組zu成cheng。在zai液ye壓ya傳chuan動dong係xi統tong中zhong的de執zhi行xing機ji構gou，是shi通tong過guo閥fa門men來lai進jin行xing控kong製zhi的de
，但dan是shi而er換huan向xiang閥fa的de閥fa芯xin和he閥fa體ti之zhi間jian會hui存cun在zai這zhe一yi些xie縫feng隙xi，這zhe就jiu會hui導dao致zhi換huan向xiang閥fa門men內nei部bu出chu現xian泄xie漏lou，僅jin僅jin依yi靠kao換huan向xiang閥fa門men是shi不bu可ke能neng讓rang執zhi行xing機ji構gou在zai處chu於yu不bu工gong作zuo情qing況kuang之zhi下xia而er不bu受shou外wai界jie影ying響xiang的de，因yin此ci就jiu要yao利li用yong單dan向xiang閥fa來lai控kong製zhi液ye壓ya油you的de流liu動dong
，從cong而er可ke靠kao地di使shi控kong製zhi執zhi行xing元yuan件jian能neng停ting在zai某mou處chu而er不bu受shou外wai界jie影ying響xiang。
