柱塞泵过度发热有两个缘由，一是机械冲突生热。因为运动外表处于干冲突或半干冲突状态，运动部件彼此冲突生热。二是液体冲突生热。高压油通过各种缝隙走漏到低压腔，很多的液压能损失转为热能。所以准确挑选运动部件之间的空隙、油箱容积和冷却器，能够杜绝泵的过度发热和油温过高的表象。另外，回油过滤器阻塞形成回油背压过高，也会引起油温过高和泵体过热。9510290358AZ-P-F-12-008-LPR12MB-S03549510290359AZ-P-F-12-014-LRR12KB9510290360AZ-P-F-12-004-RRR12KB9510290361AZ-P-F-12-005-RRR12KB9510290362AZ-P-F-12-008-RRR12KB9510290363AZ-P-F-12-011-RRR12KB9510290364AZ-P-F-12-014-RRR12KB9510290365AZPF-12-016RRR12PB-SO5569510290366AZ-P-F-12-019-RRR12KB9510290367AZ-P-F-12-004-LRR12KB9510290368AZ-P-F-12-005-LRR12KB9510290369AZ-P-F-12-008-LRR12KB9510290370AZ-P-F-12-011-LRR12KB9510290371AZ-P-F-12-019-LRR12KB9510290372AZ-P-F-12-022-LRR12KB9510290373AZ-P-FF-12-008/008-RRR12KB9510290386AZ-P-F-12-022-LRR12PB-S0012德国PGH齿轮泵rexroth齿轮泵力士乐***boschrexroth齿轮泵力士乐液压元件有限公司R900411430REXROTH力士乐叠加式溢流阀Z2DB10VC2-4X/315VR900411358Z2DB10VD2-4X/200V力士乐叠加式溢流阀)
