　　 （1）液壓系統(tǒng)設計時為提高系統(tǒng)穩(wěn)定性，減少負載變化對速度的影響，要么犧牲部分我們想實現(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，通過增加阻尼，提高系統(tǒng)速度剛度來提高系統(tǒng)的穩(wěn)定性。但是這樣元件的增加又會降低效率，浪費能源；還會使得整個系統(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，使得用戶在實現(xiàn)某一功能時必須購買相應的液壓元件，再加上工程機械廠家會根據(jù)不同*終用戶要求設計出相應的功能，這樣會造成生產(chǎn)廠家采購同類、多規(guī)格的液壓控制元件來滿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，同時會大大提高產(chǎn)品成本。 4WE10H20B/AW220-50NZ5LB10
