　　 （1）液壓系統(tǒng)設(shè)計(jì)時(shí)為提高系統(tǒng)穩(wěn)定性,，減少負(fù)載變化對(duì)速度的影響，要么犧牲部分我們想實(shí)現(xiàn)的功能,，要么增加額外的液壓元件，如調(diào)速閥、壓力控制閥等，通過(guò)增加阻尼,，提高系統(tǒng)速度剛度來(lái)提高系統(tǒng)的穩(wěn)定性。但是這樣元件的增加又會(huì)降低效率,，浪費(fèi)能源；還會(huì)使得整個(gè)系統(tǒng)的可靠性降低,、增加成本,。 D41FSE02C1NLW0

　　 （2）由于換向結(jié)構(gòu)的特殊性，使得用戶(hù)在實(shí)現(xiàn)某一功能時(shí)必須購(gòu)買(mǎi)相應(yīng)的液壓元件,，再加上工程機(jī)械廠家會(huì)根據(jù)不同*終用戶(hù)要求設(shè)計(jì)出相應(yīng)的功能,，這樣會(huì)造成生產(chǎn)廠家采購(gòu)?fù)?lèi)、多規(guī)格的液壓控制元件來(lái)滿(mǎn)足不同功能要求的需要,，不利于產(chǎn)品通用化及產(chǎn)品管理,，同時(shí)會(huì)大大提高產(chǎn)品成本。 4WE10H20B/AW220-50NZ5LB10
