?丹佛斯三聯(lián)變量柱塞泵工作原理：此泵由底閥、柱塞彈簧、泵蓋及旋轉(zhuǎn)活塞組成該泵主要用于汽車起動(dòng)時(shí)的增壓泵驅(qū)動(dòng)系統(tǒng) 1、底閥采用不銹鋼或鑄鋁材質(zhì) 閥體由一個(gè)圓環(huán)和若干個(gè)圓環(huán)構(gòu)成圓環(huán)上有若干個(gè)閥門按鈕閥門按鈕分別按在圓環(huán)上各個(gè)按鈕上。
轉(zhuǎn)動(dòng)時(shí)，按鈕分別按在相應(yīng)的開關(guān)上 2、當(dāng)汽車起動(dòng)時(shí)，在活塞桿的一端安裝了一只旋轉(zhuǎn)活塞，該旋轉(zhuǎn)活塞由活塞桿軸套固定在內(nèi)孔上 旋轉(zhuǎn)活塞的旋轉(zhuǎn)角度為15°旋轉(zhuǎn)活塞的工作方式是將內(nèi)孔裝入活塞套內(nèi)并垂直向上推入柱塞。
工作時(shí)，旋轉(zhuǎn)活塞沿柱塞和泵蓋向外運(yùn)動(dòng)，帶動(dòng)泵蓋下端面的泵壓通過柱塞和泵蓋上的止回閥傳遞到下端面的活塞套內(nèi)，從而實(shí)現(xiàn)對(duì)柱塞的密封旋轉(zhuǎn)活塞在工作時(shí)往復(fù)運(yùn)動(dòng)，使底閥保持開啟狀態(tài)使柱塞可以在柱塞和泵蓋之間旋轉(zhuǎn) 3、當(dāng)汽車啟動(dòng)時(shí)，活塞桿旋轉(zhuǎn)到該旋轉(zhuǎn)活塞運(yùn)動(dòng)位置。
此過程需要數(shù)秒時(shí)間旋轉(zhuǎn)活塞推動(dòng)泵蓋上的柱塞旋轉(zhuǎn)從而推動(dòng)汽車啟動(dòng)汽車起動(dòng)后，轉(zhuǎn)動(dòng)活塞，推動(dòng)汽車離開底閥，實(shí)現(xiàn)連續(xù)工作 4、當(dāng)汽車起停時(shí)，旋轉(zhuǎn)活塞自動(dòng)返回原位 將旋轉(zhuǎn)活塞頂出的離合器片和離合器盤間隙調(diào)整到最小。
當(dāng)發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)時(shí)，液壓油從旋轉(zhuǎn)活塞處流出，形成柱塞運(yùn)動(dòng)因此汽車發(fā)動(dòng)機(jī)起動(dòng)時(shí)需要較大動(dòng)力來驅(qū)動(dòng)旋轉(zhuǎn)活塞，從而增加了增壓泵驅(qū)動(dòng)系統(tǒng)中的能量消耗當(dāng)活塞移動(dòng)到旋轉(zhuǎn)活塞時(shí)，柱塞在活塞中間被擠壓，使其頂出，并通過底閥實(shí)現(xiàn)增壓泵驅(qū)動(dòng)系統(tǒng)中所需的壓力，從而降低了增壓泵所需的功率水平，改善了增壓泵驅(qū)動(dòng)系統(tǒng)的性能。
在機(jī)械設(shè)備領(lǐng)域有許多相關(guān)的技術(shù)和解決方案；在液壓領(lǐng)域有許多相關(guān)的技術(shù)和解決方案 5、當(dāng)汽車完成制動(dòng)動(dòng)作，旋轉(zhuǎn)活塞再次返回工作位置 在這一過程中，旋轉(zhuǎn)活塞將會(huì)連續(xù)工作當(dāng)汽車剎車時(shí)，旋轉(zhuǎn)活塞會(huì)在制動(dòng)行程中移動(dòng)數(shù)厘米。
當(dāng)旋轉(zhuǎn)活塞移動(dòng)到上一個(gè)行程時(shí)，汽車停止制動(dòng)旋轉(zhuǎn)活塞的移動(dòng)速度約為4米/秒這樣，旋轉(zhuǎn)活塞在汽車停止制動(dòng)前便可以完成制動(dòng)任務(wù) 90-L-100-DD-1-AB-60-R-4-S1-F-GB-GBA-35-35-24 90L100DD1AB60R4S1FGBGBA353524 90-L-100-DD-1-BC-80-L-4-F1-E-GB-GBA-42-42-24 90L100DD1BC80L4F1EGBGBA424224 90-L-100-DD-1-BC-80-R-3-C7-F-GJ-GBA-29-29-24 90L100DD1BC80R3C7FGJGBA292924 90-L-100-DD-1-BC-80-R-4-F1-E-G8-GBA-42-42-24 90L100DD1BC80R4F1EG8GBA424224 90-L-100-DD-1-BC-80-R-4-F1-E-GB-GBA-42-42-24 90L100DD1BC80R4F1EGBGBA424224 90-L-100-DD-1-CD-60-P-3-C7-E-GB-GBA-42-42-24 90L100DD1CD60P3C7EGBGBA424224 90-L-100-DD-1-CD-80-R-3-C7-F-G1-GBA-35-35-24 90L100DD1CD80R3C7FG1GBA353524 90-L-100-DD-1-CD-80-S-3-C7-E-GB-GBA-35-35-24 90L100DD1CD80S3C7EGBGBA353524 90-L-100-DD-1-NN-60-R-4-C7-F-GJ-GBA-32-32-24 90L100DD1NN60R4C7FGJGBA323224 90-L-100-DD-1-NN-80-L-4-F1-E-GB-GBA-42-42-24 90L100DD1NN80L4F1EGBGBA424224 90L100-DD-1-NN-80-P-4-F1-F-GB-GBA-35-35-24 90L100DD1NN80P4F1FGBGBA353524 90-L-100-DD-1-NN-80-P-4-F1-F-GB-GBA-35-35-24 90L100DD1NN80P4F1FGBGBA353524 90-L-100-DD-1-NN-80-R-3-S1-F-G1-GBA-35-35-24 90L100DD1NN80R3S1FG1GBA353524 90-L-100-DD-1-NN-80-R-4-F1-F-GB-GBA-14-14-24 90L100DD1NN80R4F1FGBGBA141424 90L100-DD-1-NN-80-R-4-F1-F-GB-GBA-14-14-24 90L100DD1NN80R4F1FGBGBA141424 90-L-100-DD-1-NN-80-S-3-C7-E-GB-GBA-29-29-24 90L100DD1NN80S3C7EGBGBA292924 90-L-100-DD-1-NN-81-L-3-F1-E-GB-GBA-42-42-24 90L100DD1NN81L3F1EGBGBA424224 90-L-100-DD-1-NN-81-L-4-F1-E-GB-GBA-42-42-24 90L100DD1NN81L4F1EGBGBA424224 90-L-100-DD-5-AB-60-P-4-S1-E-G8-GBA-35-35-24 90L100DD5AB60P4S1EG8GBA353524 90L100-DD-5-AB-60-S-3-C7-E-GF-GBA-42-42-24 90L100DD5AB60S3C7EGFGBA424224 90-L-100-DD-5-AB-60-S-3-C7-E-GF-GBA-42-42-24 90L100DD5AB60S3C7EGFGBA424224 90L100-DD-5-AB-80-S-3-C7-E-GB-GBA-42-42-24 90L100DD5AB80S3C7EGBGBA424224 90-L-100-DD-5-AB-80-S-3-C7-E-GB-GBA-42-42-24 90L100DD5AB80S3C7EGBGBA424224 90L100-DD-5-BB-80-S-4-C7-E-GB-GBA-42-42-24 90L100DD5BB80S4C7EGBGBA424224 90-L-100-DD-5-BB-80-S-4-C7-E-GB-GBA-42-42-24 90L100DD5BB80S4C7EGBGBA424224 90-L-100-DD-5-BC-80-R-4-F1-E-GB-GBA-23-38-24 90L100DD5BC80R4F1EGBGBA233824 90L100-DD-5-BC-80-S-4-C7-E-GB-GBA-38-38-24 90L100DD5BC80S4C7EGBGBA383824 90-L-100-DD-5-BC-80-S-4-C7-E-GB-GBA-38-38-24 90L100DD5BC80S4C7EGBGBA383824 90L100-DD-5-BC-80-S-4-S1-F-G1-GBA-42-42-20 90L100DD5BC80S4S1FG1GBA424220 90-L-100-DD-5-BC-80-S-4-S1-F-G1-GBA-42-42-20 90L100DD5BC80S4S1FG1GBA424220 90-L-100-DD-5-CD-60-P-4-T2-E-G8-GBA-35-35-24 90L100DD5CD60P4T2EG8GBA353524 90L100-DD-5-CD-60-S-3-C7-E-GB-GBA-35-35-30 90L100DD5CD60S3C7EGBGBA353530 90-L-100-DD-5-CD-60-S-3-C7-E-GB-GBA-35-35-30 90L100DD5CD60S3C7EGBGBA353530 90L100-DD-5-NN-60-P-4-S1-E-GB-GBA-30-30-24 90L100DD5NN60P4S1EGBGBA303024 90-L-100-DD-5-NN-60-P-4-S1-E-GB-GBA-30-30-24 90L100DD5NN60P4S1EGBGBA303024 90L100-DD-5-NN-80-P-4-C6-E-G1-GBA-30-30-24 90L100DD5NN80P4C6EG1GBA303024 90-L-100-DD-5-NN-80-P-4-C6-E-G1-GBA-30-30-24 90L100DD5NN80P4C6EG1GBA303024 。
