阿托斯ATOS變量葉片泵/意大利阿托斯變量葉片泵
ATOS變量葉片泵推動高粘流體進入吸入口
一側的兩齒空間是非常重要的，如果這一空間沒有填充滿，則泵就不能排出準確的流量，所以PV值(壓力×流速)也是另外一個限制因素，而且是一個工藝變量。由于這些限制，齒輪泵制造商將提供一系列產品，即不同的規格及排量(每轉一周所排出的量)。
這些泵將與具體的應用工藝相配合，以使系統能力及價格達到優。
ATOS阿托斯油缸在電液脈沖伺服油缸是由步進電機、三位四通伺服閥、機械反饋裝置(絲扛副)和油杠組成。
當步進電機得到一個脈沖信號時其輸出軸旋轉1.5或3度角度，伺服閥閥芯帶動絲扛同時旋轉，閥芯移動并開口換向油缸輸出壓力油，活塞移動并帶動絲杠反向旋轉使閥芯退回原位，伺服閥復中位停止輸出壓力油。

變量葉片泵的定子內表面是一個圓形，轉子與定子間有偏心距，在配油盤上只開有一個吸油窗口和一個壓油窗口。當轉子在電動機驅動下按圖示箭頭方向旋轉時，葉片經定子下半部時，在離心力的作用下，從葉片槽中伸出，兩葉片間的密封容積增大，實現吸油；葉片經定子上半部時，被定子內表面逐漸壓入葉片槽內，密封容積減少，實現壓油。泵的轉子每轉一轉，每個密封容積吸、壓油各一次。改變定子和轉子間的偏心量，便可改變泵的排量，故稱為變量葉片泵。
阿托斯變量葉片泵PVT-322授權經銷使用要點
1.為了使葉片泵可靠地吸油，其轉速必須在500～1500r/min的范圍，轉速太低時，葉片不能緊壓定子的內表面和吸油；轉速太高則造成泵的“吸空”現象，泵的工作不正常。油的粘度要選用適當，粘度太大，吸油阻力增大；油液過稀，間隙影響，真空度不夠，會對吸油造成不良影響。
2.葉片泵對油中的污物很敏感，工作可靠性較差，油液不清會使葉片卡死，因此必須注意油液良好過濾和環境清潔。
3.因泵的葉片有安裝傾角，故轉子只允許單向旋轉，不應反向使用，否則會使葉片折斷。
特性
1.可在壓力設定下具有自動高速流量及補償功能，比定量葉片泵功率損耗少，發熱低，是一種節省能源的高效率葉片泵，為系統設計工程師在高效率的回路中佳選擇。
2.運轉平衡安靜，特別適合機床和室內的要求。
3.內含壓力調整機構，系統可以不要調壓閥并且適用直接式電動機，裝配容易。
4.備有多種不同壓力及流量范圍，可供任意選擇。
區別
1.在變量葉片泵中,當葉片處于壓油區時,葉片底部通壓力油,當葉片處于吸油區時,葉片底部通吸油腔,這樣,葉片的頂部和底部的液壓力基本平衡,這就避免了定量葉片泵在吸油區定子內表面嚴重磨損的問題.如果在吸油腔葉片底部仍通壓力油,葉片頂部就會給定子內表面以較大的摩擦力,以致減弱了壓力反饋的作用。
2.葉片也有傾角,但傾斜方向正好與定量葉片泵相反,這是因為變量葉片泵的葉片上下壓力是平衡的,葉片在吸油區向外運動主要依靠其旋轉時的離心慣性作用.根據力學分析,這樣的傾斜方向更有利于葉片在離心慣性作用下向外伸出。
3.變量葉片泵結構復雜,輪廓尺寸大,相對運動的機件多,泄漏較大,軸上承受不平衡的徑向液壓力,噪聲較大,容積效率和機械效率都沒有定量葉片泵高;但是,它能按負載壓力自動調節流量,在功率使用上較為合理,可減少油液發熱。
變量葉片泵與定量葉片泵的區分是甚么？
在轉速恒定的條件下，壓力不變輸出流量可調動的的為變量葉片泵，壓力不變而流量也不可調為定量葉片泵。他們大的不同就是變量葉片泵的軸是便心安裝。簡單來講定量葉片泵的轉速選定后，他的流量和壓力就肯定了，就不能調理。變量葉片泵的輸出流量可以根據液壓系統的壓力變化（外負載的大小），自動地調理流量，就是壓力高時輸出流量小，壓力低時輸出流量大，這樣他可以節省液壓元件的數量，從而簡化了油路系統，而且可以減少油發熱。缺點是流量脈動嚴重，液壓系統壓力不安穩，泵的壽命短，泵的軸承容易壞，由于他是便心安裝，而且泵的嘈音大。 葉片泵通過調理偏心距、柱塞泵通過調理滑板角度可以實現變量。定量葉片泵的工作原理：定子、轉子配流盤所構成的密封容積被葉片分割為若干，轉子每轉1周，每一個密封空間完成兩次吸油和壓油，所以被稱為定量葉片泵。變量葉片泵的工作原理：變量葉片泵可以通過改變轉子和定子的偏心距e來調理泵的流量，使液壓系統在工作進給時能量利用公道，效力高，油的溫升小。
