柱塞泵特點(diǎn):∵圓形構(gòu)件配合，加工方便，精度高，密封性好 ∴有如下特點(diǎn) （1）工作壓力高，效率高 （2）易于變量 （3）流量范圍大柱塞泵分類 軸向柱塞泵特征：柱塞軸線平行或傾斜于缸體的軸線 軸向柱塞泵的組成：配油盤、柱塞、缸體、傾斜盤等 V密形成—柱塞和缸體配合而成 V密變化，缸體逆轉(zhuǎn),右半周，V密增大，吸油(左半周，V密減小，壓油) 吸壓油口隔開—配油盤上的封油區(qū)及缸體底部的通油孔 軸向柱塞泵變量原理 γ=0q=0γ(大小變化，流量大小變化;方向變化，輸油方向變化) 當(dāng)缸體轉(zhuǎn)動(dòng)時(shí)，泵的排量為：V=Zhπd2/4=πd2ZD(tanγ)/4 軸向柱塞泵流量 理論流量：qT=Vn=D(tanγ)·zπd2/4 實(shí)際流量：q=qTηpv=D(tanγ)·zηpvπd2/4 結(jié)論 1)qT=f(幾何參數(shù)、n、γ) 2）n=c，γ=0，q=0,γ(大小變化，流量大小變化;方向變化，輸油方向變化),所以軸向柱塞泵可作雙向變量泵 軸向柱塞泵主體:中心彈簧機(jī)構(gòu) A滑靴和斜盤 B柱塞和缸體 中心彈簧:使泵具有自吸性能,提高容積效率 缸體端面間隙的自動(dòng)補(bǔ)償:中心彈簧,缸體底部通油孔p 缸體端面間隙的自動(dòng)補(bǔ)償：柱塞孔底部的液壓除中央彈簧外，還使缸體靠近配流盤，補(bǔ)償端面間隙，提高體積效率。
柱塞頭部結(jié)構(gòu)：球形頭部-與斜盤接觸，接觸應(yīng)大，易磨損滑靴結(jié)構(gòu)-與斜盤接觸面接觸，大大減少了磨損 變量機(jī)構(gòu):手動(dòng):—轉(zhuǎn)動(dòng)手輪控制斜盤，改變傾角即可;自動(dòng) 液壓馬達(dá)功能：將液體的壓力能轉(zhuǎn)化為旋轉(zhuǎn)機(jī)械能，并對負(fù)荷工作。
液壓馬達(dá)分類： 按照排量能否調(diào)節(jié)：定量和變量 可根據(jù)輸油方向改變：單向和雙向： 按照輸出轉(zhuǎn)矩是否連續(xù)：旋轉(zhuǎn)式和擺動(dòng)式 液壓電機(jī)的工作原理：當(dāng)壓力油進(jìn)入電機(jī)時(shí)，柱塞在油壓下壓力傾斜板，而傾斜板對柱塞產(chǎn)生反作用力，由于傾斜力可分解為兩個(gè)力(軸向力Fx=πd2p//4；徑向分力Fy=γ=π/4·d2ptanγ），F(xiàn)x與液壓平衡，F(xiàn)y在缸體中心產(chǎn)生扭矩，使缸體驅(qū)動(dòng)電機(jī)軸旋轉(zhuǎn)。
液壓馬達(dá)主要參數(shù) p.V.q等與泵相似，其原則差別:泵—輸出,馬達(dá)—輸入 液壓電機(jī)轉(zhuǎn)矩及機(jī)械效率：Tt=ΔpV/2π，T=Ttηm=ΔpVηm/2π 液壓馬達(dá)轉(zhuǎn)速和容積效率:nt=q/v n=qηv/V ∵T∝Vn∝1/V ∴V↑、T↑、n↓,故馬達(dá)又可分為高速小轉(zhuǎn)矩和低速大轉(zhuǎn)矩 各類液壓泵的共同點(diǎn)和不同處 流量的形成：依靠密封容積的變化吸、壓油，從而形成連續(xù)不斷的供油。
流量調(diào)節(jié)：齒輪泵、葉片泵、螺桿泵均為定量泵、可變?nèi)~片泵、徑向柱塞泵、偏心距離、軸向柱塞泵、斜盤(或斜軸)傾角 困油現(xiàn)象：除螺桿泵外皆有，齒輪泵最嚴(yán)重，其他泵設(shè)計(jì)合理可減小或消除 流量脈動(dòng)： 齒輪泵：取決于齒數(shù)、嚙合角 葉片泵：取決于葉片數(shù)和過渡曲線類型 柱塞泵：取決于柱塞數(shù)和配流盤參數(shù) 液壓泵選用原則： 可靠—工作情況、要求 合理—能量使用 實(shí)用—使用情況 經(jīng)濟(jì)—價(jià)廉 90L075-DC-1-AB-60-S-3-C7-D-GB-GBA-42-42-24 90L075DC1AB60S3C7DGBGBA424224 90-L-075-DC-1-AB-60-S-3-C7-D-GB-GBA-42-42-24 90L075DC1AB60S3C7DGBGBA424224 90-L-075-DC-1-AB-80-R-4-S1-E-GB-GBA-42-42-24 90L075DC1AB80R4S1EGBGBA424224 90-L-075-DC-1-BB-80-S-4-S1-D-G8-GBA-42-42-24 90L075DC1BB80S4S1DG8GBA424224 90-L-075-DC-1-BC-60-P-4-C6-D-GB-GBA-35-35-24 90L075DC1BC60P4C6DGBGBA353524 90-L-075-DC-1-BC-60-P-4-S1-D-GB-GBA-35-35-24 90L075DC1BC60P4S1DGBGBA353524 90-L-075-DC-1-BC-80-S-4-S1-D-GB-GBA-35-35-24 90L075DC1BC80S4S1DGBGBA353524 90-L-075-DC-1-CD-60-R-3-C7-C-GB-GBA-38-38-24 90L075DC1CD60R3C7CGBGBA383824 90-L-075-DC-1-CD-60-R-3-S1-D-GB-GBA-42-42-24 90L075DC1CD60R3S1DGBGBA424224 90-L-075-DC-1-CD-80-R-3-C7-C-GB-GBA-38-38-24 90L075DC1CD80R3C7CGBGBA383824 90-L-075-DC-1-CD-80-R-4-S1-D-GB-GBA-35-35-24 90L075DC1CD80R4S1DGBGBA353524 90-L-075-DC-1-CD-80-R-4-S1-D-GB-GBA-35-35-24-F053 90L075DC1CD80R4S1DGBGBA353524F053 90-L-075-DC-1-CD-80-S-3-S1-D-G8-GBA-35-35-24 90L075DC1CD80S3S1DG8GBA353524 90-L-075-DC-1-CD-80-S-3-S1-E-GB-GBA-42-42-24 90L075DC1CD80S3S1EGBGBA424224 90-L-075-DC-1-CD-80-S-4-S1-D-G8-GBA-35-35-24 90L075DC1CD80S4S1DG8GBA353524 90-L-075-DC-1-CD-80-S-4-S1-D-G8-GBA-42-42-24 90L075DC1CD80S4S1DG8GBA424224 90-L-075-DC-1-NN-60-R-4-T1-D-GB-GBA-29-29-24 90L075DC1NN60R4T1DGBGBA292924 90L075-DC-1-NN-60-S-3-S1-D-GB-GBA-32-32-24 90L075DC1NN60S3S1DGBGBA323224 90-L-075-DC-1-NN-60-S-3-S1-D-GB-GBA-32-32-24 90L075DC1NN60S3S1DGBGBA323224 90-L-075-DC-1-NN-80-L-3-S1-D-GB-GBA-35-35-24 90L075DC1NN80L3S1DGBGBA353524 90-L-075-DC-1-NN-80-P-4-S1-C-GB-GBA-38-38-24 90L075DC1NN80P4S1CGBGBA383824 90-L-075-DC-1-NN-80-P-4-S1-D-GB-GBA-38-38-24 90L075DC1NN80P4S1DGBGBA383824 90-L-075-DC-1-NN-80-P-4-S1-D-GB-GBA-42-42-24 90L075DC1NN80P4S1DGBGBA424224 90-L-075-DC-1-NN-80-R-3-S1-D-GB-GBA-35-35-20 90L075DC1NN80R3S1DGBGBA353520 90-L-075-DC-1-NN-80-R-4-S1-C-G8-GBA-20-32-20 90L075DC1NN80R4S1CG8GBA203220 90-L-075-DC-1-NN-80-S-3-C7-D-GB-GBA-35-35-24 90L075DC1NN80S3C7DGBGBA353524 90-L-075-DC-1-NN-80-S-3-S1-D-GB-GBA-35-35-24 90L075DC1NN80S3S1DGBGBA353524 90-L-075-DC-1-NN-80-S-4-S1-D-GB-GBA-35-35-24 90L075DC1NN80S4S1DGBGBA353524 90L075-DC-5-AB-80-P-4-S1-D-GB-GBA-20-20-20 90L075DC5AB80P4S1DGBGBA202020 90-L-075-DC-5-AB-80-P-4-S1-D-GB-GBA-20-20-20 90L075DC5AB80P4S1DGBGBA202020 90L075-DC-5-AB-80-R-4-C6-D-GB-GBA-42-42-24 90L075DC5AB80R4C6DGBGBA424224 90-L-075-DC-5-AB-80-R-4-C6-D-GB-GBA-42-42-24 90L075DC5AB80R4C6DGBGBA424224 90L075-DC-5-AB-80-S-3-S1-E-GB-GBA-35-35-24 90L075DC5AB80S3S1EGBGBA353524 90-L-075-DC-5-AB-80-S-3-S1-E-GB-GBA-35-35-24 90L075DC5AB80S3S1EGBGBA353524 90L075-DC-5-AB-80-S-4-C7-E-GB-GBA-42-42-24 90L075DC5AB80S4C7EGBGBA424224 90-L-075-DC-5-AB-80-S-4-C7-E-GB-GBA-42-42-24 90L075DC5AB80S4C7EGBGBA424224 90L075-DC-5-AB-80-S-4-S1-E-GB-GBA-35-35-24 90L075DC5AB80S4S1EGBGBA353524 90-L-075-DC-5-AB-80-S-4-S1-E-GB-GBA-35-35-24 90L075DC5AB80S4S1EGBGBA353524 90L075-DC-5-BC-60-S-3-S1-D-GB-GBA-35-35-24 90L075DC5BC60S3S1DGBGBA353524 90-L-075-DC-5-BC-60-S-3-S1-D-GB-GBA-35-35-24 90L075DC5BC60S3S1DGBGBA353524 90-L-075-DC-5-BC-80-R-3-S1-E-G8-GBA-38-38-24 90L075DC5BC80R3S1EG8GBA383824 90-L-075-DC-5-BC-80-S-3-S1-E-G8-GBA-38-38-24 90L075DC5BC80S3S1EG8GBA383824 90L075-DC-5-CD-60-S-3-S1-D-GB-GBA-35-35-24 90L075DC5CD60S3S1DGBGBA353524 90-L-075-DC-5-CD-60-S-3-S1-D-GB-GBA-35-35-24 90L075DC5CD60S3S1DGBGBA353524 90-L-075-DC-5-CD-80-R-3-C6-E-G8-GBA-38-38-24 90L075DC5CD80R3C6EG8GBA383824 90-L-075-DC-5-CD-80-S-3-C6-E-G8-GBA-38-38-24 90L075DC5CD80S3C6EG8GBA383824 90L075-DC-5-NN-60-S-3-C7-D-GB-GBA-42-42-24 90L075DC5NN60S3C7DGBGBA424224 90-L-075-DC-5-NN-60-S-3-C7-D-GB-GBA-42-42-24 90L075DC5NN60S3C7DGBGBA424224 90L075-DC-5-NN-60-S-4-S1-D-GF-GBA-40-40-24 90L075DC5NN60S4S1DGFGBA404024 90-L-075-DC-5-NN-60-S-4-S1-D-GF-GBA-40-40-24 90L075DC5NN60S4S1DGFGBA404024 90L075-DC-5-NN-80-L-4-S1-D-GB-GBA-42-42-24 90L075DC5NN80L4S1DGBGBA424224 90-L-075-DC-5-NN-80-L-4-S1-D-GB-GBA-42-42-24 90L075DC5NN80L4S1DGBGBA424224 90L075-DC-5-NN-80-S-4-S1-E-GB-GBA-35-35-24 90L075DC5NN80S4S1EGBGBA353524 90-L-075-DC-5-NN-80-S-4-S1-E-GB-GBA-35-35-24 90L075DC5NN80S4S1EGBGBA353524 90L075-DC-5-NN-80-S-4-S1-E-GB-GBA-40-40-28 90L075DC5NN80S4S1EGBGBA404028 90-L-075-DC-5-NN-80-S-4-S1-E-GB-GBA-40-40-28 90L075DC5NN80S4S1EGBGBA404028。
