液壓馬達的主要參數

本文蘇州逐利跟大家來聊一聊液壓馬達的主要參數，一般有壓力、轉速、排量與流量、功率與效率等。

(1)壓力

①工作壓力p 液壓馬達實際工作時的輸入壓力稱為液壓馬達的工作壓力。液壓馬達的工作壓力取決于負載轉矩及排油壓力（背壓力）的大小。

②額定壓力pn 在正常工作條件下，按試驗標準規定能連續運轉的最高壓力，稱為液壓馬達的額定壓力，額定壓力又稱為公稱壓力。液壓馬達的額定壓力受馬達本身的結構強度、泄漏等因素的制約，超過此值就是過載。各類液壓馬達的額定壓力范圍。

③最高允許壓力pmax 按試驗標準規定，超過額定壓力允許短暫運行的最高壓力，稱為液壓馬達的最高允許壓力，簡稱最高壓力。 液壓泵及液壓馬達的主要參數及共性問題 。

④壓力差△p 馬達的進油口壓力與出油口壓力之差稱為液壓馬達的壓力差。當馬達的排油壓力近似為零時，可用馬達的進口工作壓力來代替△p。

⑤最低回油背壓為避免出現脫空現象，液壓馬達排油腔必須保持的最低壓力稱為最低回油背壓。 液壓馬達壓力的計量單位、壓力系列及壓力分級與液壓泵相同。

(2)轉速

①額定轉速n  在額定壓力下，能夠長時間正常運轉的最高轉速，稱為液壓馬達的額定轉速。

②最高轉速nmax  在額定壓力下，超過額定轉速允許短暫運行的轉速，稱為液壓馬達的最高轉速。

③最低轉速nmin  正常運轉所允許的最低轉速，稱為液壓馬達的最低轉速。轉速的計量單位與液壓泵相同，各類液壓馬達的轉速范圍可參考相關液壓馬達樣書。

(3)排量與流量

①排量V   液壓馬達軸每轉一轉（或一弧度），由其密封容腔幾何尺寸變化計算而得到的流入液體的體積，稱為液壓馬達的理論排量（簡稱排量），也即在無泄漏的情況下，馬達軸轉一轉所能進入的液體體積。排量的法定計量單位與液壓泵相同。液壓馬達的公稱排量系列可參考各類液壓馬達樣書。

②理論流量g  液壓馬達在單位時間內由其密封容腔幾何尺寸變化計算而得到的輸入的液體體積，也即在無泄漏的情況下單位時間內所能輸入的液體體積，稱為液壓馬達的理論流量，一般是指不計液壓馬達輸入的液體的脈動性的平均理論流量。 馬達流量的計量單位與液壓泵相同。 液壓馬達理論流量g與泵的排量V之間的關系式如下

③瞬時流量qi  馬達在每一瞬時的流量稱為液壓馬達的瞬時流量，一般指瞬時理論（幾何）流量，該流量具有一定的脈動性。

④平均流量g1  按平均時間計算出的流量稱為液壓馬達的平均流量。

⑤額定流量g2  液壓馬達在額定壓力和額定轉速下運轉時，按試驗標準規定，液壓馬達必須保證的輸入流量稱為額定流量。

⑥實際流量q液壓馬達工作時實際輸入的流量，稱為液壓馬達的實際流量。 由于液壓馬達工作時由于泄漏等要損失部分流量，故液壓馬達實際流量q大于馬達的理論流量qt 。

(4)功率及效率

液壓馬達用于驅動負載實現回轉運動，輸入的是液壓能，表現為液體的壓力和流量。
