产品聚焦 - 优势

机油泵将来自油箱的机油通过机油滤清器和冷油器输送至发动机润滑点。

发动机润滑系统的任务是向发动机部件提供足够的润滑油。
该系统是个封闭系统,机油必须在其中承担多项任务。

  • 所有滑行部件的润滑
  • 发动机部件的冷却 – 防止过热
  • 清除沉积物、燃烧残留物和磨损
  • 腐蚀防护
  • 降低噪音和振动
  • 精密密封(例如活塞环)
  • 力传递

若要实现充足的冷却和润滑,机油泵必须通过电机泵动整个油量每分钟 4 - 6 次。 此外,设计时必须使得润滑部位在冷启动后尽可能快地得到新鲜机油的供给。即便在低转速情况下,供给量也是充足的。

无论是气门控制机构还是铝制轻金属发动机缸体,现代化的发动机向机油和润滑剂提出越来越多的挑战。 必须同时径向抑制泵的能源消耗量,以便将 CO2 的排放保持尽可能的低。

若要完成部分为全新的机油液压任务,如液压气门间隙平衡和凸轮轴平衡、活塞冷却等等,现代化的发动机在低转速范围内需要超常的大机油流量。 对于传统、非调节的泵,若直接耦合到处于较高转速范围的发动机,则会造成明显的功率损失。 机械或电气控制的机油泵可以根据需求而独立于转速状况供给机油,因此效率更高。

高寿命和高效率是我们机油泵所树立的标杆。

  • 机油泵通常整套更换,无法进行单独的机油泵维修。
  • 机油泵使用寿命长,但是可能由于维修不当、油品差、油稀释、污垢或发动机损伤而缩短使用寿命。这些也可能导致提前更换机油泵。

规格

结构型式和泵的规格

  • 商用车发动机的油泵通常采用齿轮或链条传动式设计。此类泵由曲轴传动机构间接驱动。
  • 得益于其结构型式,采用齿轮或插装式驱动装置的油泵较链条传动式油泵更容易更换。
  • 转子泵基于其结构原理,可以提供高输送功率和高压力。
  • 内啮合齿轮油泵的优点在于输送功率较高,特别是在低转速的情况下。
  • 机油泵的驱动可通过用于曲轴直接驱动和辅助驱动的外齿轮、内齿轮来完成。
  • 现代乘用车和商用车使用可调式油泵,它可以按需满输送油量、节约燃油。
