可選接線方式：DIN43650插頭式、接線盒式；緩閉止回閥2GG9P14緩閉止回閥
緩閉止回閥2GG9P143.液壓缸的基座必須有足夠的剛度，否則加壓時缸筒成弓形向上翹，使活塞桿彎曲。50T:50T-07,50T-12,50T-14,50T-17,50T-20,50T-23,50T-26L,50T-30,50T-36,50T-39.50T-07-F-R,50T-12-F-R,50T-14-F-R,50T-17-F-R,50T-20-F-R,50T-23-F-R,50T-26-F-R,50T-30-F-R,50T-36-F-R,50T-39-F-R.50T-07-L-R,50T-12-L-R,50T-14-L-R,50T-17-L-R,50T-20-L-R,50T-23-L-R,50T-26-L-R,50T-30-L-R,50T-36-L-R,50T-39-L-R.
VP-20-20 VP30-30雙聯變量葉片油泵如泵軸和電機軸不同心或頂死，旋轉軸的軸承、聯軸節(jié)損傷，彈性墊破損和裝配螺栓松動均會產生噪聲。對于高速運轉或傳輸大能量的泵，要定期檢查，記錄各部件的振幅、頻率和噪聲。如泵的轉動頻率與壓力閥的固有頻率相同時，將會引起共振，可改變泵的轉速以消除共振。緩閉止回閥2GG9P14
