北京華德液壓A2F28R4P4主油泵 通過調節(jié)斜盤的傾角可改變泵的排量。柱塞泵是往復泵的一種,屬于體積泵,其柱塞靠泵軸的偏心轉動驅動,往復運動,其吸入和排出閥都是單向閥。當柱塞外拉時,工作室內壓力降低,出口閥關閉,低于進口壓力時,進口閥打開,液體進入;柱塞內推時,工作室壓力升高,進口閥關閉,高于出口壓力時,出口閥打開,液體排出。當傳動軸帶動缸體旋轉時,斜盤將柱塞從缸體中拉出或推回,完成吸排油過程。柱塞與缸孔組成的工作容腔中的油液通過配油盤分別與泵的吸、排油腔相通。變量機構用來改變斜盤的傾角,通過調節(jié)斜盤的傾角可改變泵的排量。若回路負載持續(xù)上升,泵的壓力也持續(xù)上升,當屬正常。若負載一定,泵的壓力超過負載所需壓力值,則應檢查泵以外的液。 油箱容積和冷卻器,可以杜絕泵的過度發(fā)熱和油溫過高的現象,另外,回油過濾器堵塞造成回油背壓過高,也會引起油溫過高和泵體過熱,2.中位時排油量不為零6.液壓泵過熱(2)管道內液流產生的噪聲進油管道太細,進油濾油器通流能力過小或堵塞。VDR系列油泵具有以下幾個特點:壓力在14MPa穩(wěn)定地高效運行,高精密度的瞬時響應性, 高壓區(qū)域,低噪音的動作,降低動力損失,耐惡劣環(huán)境的堅實構造。
——產品說明 1:板式連接;管式連接;三中壓力調節(jié)裝置:手柄,帶保護罩的內六角螺栓,帶鎖手柄;五種調定壓力 2:DC型壓力控制閥是由閥體,直動式溢流閥和單向閥組合而成的平衡閥。它用來保護液壓的負載。油缸上升時壓力油可以自由地通過。而在下降時回油管內產生壓力,因而防止油缸因自重而下降
