技术领域
本发明一般地涉及润滑***。更加具体地，本发明涉及用于移动润滑***的泵马达的电子控制***。
背景技术
工业和建筑机械常常需要润滑以运行。这些机械的密封件、活塞和轴承可能需要大量的润滑脂、机油或者其它润滑剂，以保护免受磨损，防止腐蚀，和/或减少摩擦生热。移动机械常常被并入工业车辆中或者由工业车辆运送，工业车辆通常使用便携式本地润滑组件，其中，本地润滑剂泵、储存器和注射器被固定到车辆或装置以确保充分的润滑。本地储存器具有足够处理扩展的普通操作的有限容量，并且视需要，用来自更大源的润滑剂补充本地储存器。本地润滑剂组件常常将润滑剂供应到不同机械专用的多个润滑剂注射器。
发明内容
在第一实施例中，用于润滑剂泵马达的马达控制***包括泵***电能输入部、马达驱动器、电流传感器、润滑控制器和驱动器控制器。泵***电能输入部被构造成供应***电能。马达驱动器被构造成使用***电能驱动润滑剂泵马达。电流传感器被布置在泵***电能输入部和马达驱动器之间以感测***电能的输入电流。润滑控制器被构造成提供马达激励信号。驱动器控制器被布置成经由单独数字输入部接收马达激励信号，并且响应于激励信号根据感测到的输入电流和用户定义的电流设定点控制马达驱动器。
在第二实施例中，润滑***包括润滑剂储存器、被构造成从润滑剂储存器吸取流体的润滑剂泵、泵马达、***电能输入部、润滑控制器和马达控制器。泵马达被构造成驱动润滑剂泵，并且***电能输入部提供电输入电能，以驱动泵马达。润滑控制器被构造成向泵马达提供激励信号。马达控制器被布置成作为单独数字输入部接收激励信号，并且响应于激励信号、根据用户定义的电流设定点和电输入电能的感测到的电流使用驱动器控制器控制从***电能输入部输送到泵马达的电能。
附图说明
图1是润滑***的示意图。
图2是图1的润滑***的一部分的分解视图。
图3是用于图1的润滑***的电子泵马达控制***的示意性框图。
具体实施方式
本发明的润滑***包括电子泵马达控制器，该电子泵马达控制器作为单独数字输入部接收激励指令，并且响应于激励指令(激励指令是用户定义的电流设定点与感测到的输入电流的函数)使用运行控制回路的驱动器控制器来产生马达控制信号。
图1是接收、储存和供应润滑剂流体的润滑***10的示意图。润滑***10包括本地组件12，本地组件12具有润滑剂储存器14、马达16、泵18、流体管20、输入/输出歧管22、润滑剂工作管线24和润滑剂注射器26。来自补充源28的润滑剂流体能经由补充管线30、截流阀组件32和储存器入口管线34供应到润滑剂储存器14。补充泵36对来自补充源28的流体加压，并且***管线38能从补充管线30将过量的润滑剂排出到润滑剂***槽40中。

图2是本地组件12的一部分的分解视图，图示如上所述的润滑剂储存器14、马达16、泵18、流体管20、入口/输出歧管22、截流阀组件32和入口管线34。图2进一步描绘盖板44、密封环46、随动板48、储存器唇缘50、柔性隔膜52、填充板54、主入口56、主出口58、通风阀螺线管60、补充入口62、补充出口64和通气孔66。

在所描绘的实施例中，入口/输出歧管22配备有通风阀螺线管60，通风阀螺线管60是驱动一体化到入口/输出歧管22的通风阀的致动器螺线管。通风阀螺线管60根据来自润滑控制器42的输出信号Co中所包括的指令信号致动入口/输出歧管22中的阀门。以这种方式，入口/输出歧管22能够在泵送和通风模式之间切换。在泵送模式中，泵18能通过主出口58将流体从润滑剂储存器14驱动到润滑剂工作管线24，和/或润滑剂储存器14能通过主入口56接收从补充源28泵送的补充润滑剂。在通风模式下，润滑剂工作管线24中的加压流体被允许通过入口歧管22的入口通道循环回到作为压力释放机构的润滑剂储存器14中。
图3是电子控制***100的示意性框图，电子控制***100是用于马达16的泵马达控制***。电子控制***100支配马达16的电能供应和作为结果发生的泵18的操作。电子控制***100包括马达16、润滑控制器42、***电能输入部102、马达控制器104、驱动器控制器106、逻辑电能供应部108、单独数据输入部110、电流传感器112、用户输入装置114和马达驱动器116。
如关于图1和图2所述的，润滑控制器42是与马达16通信的并且在一些实施例中与润滑***10的其它部件通信的控制装置。***电能输入是到诸如电池、发电机或电网线的本地电源的电能连接。***电能输入部102能例如是到直流(DC)电源的电连接部。马达控制器104是专用于马达16的控制逻辑***。在一些实施例中，马达控制器104能被合并(例如在印刷配线板上)在马达16的外壳内。马达控制器104接收来自润滑控制器42的激励指令Ca和来自的***电源102的输入电能PI。激励指令Ca指定马达16何时应开动和关停。马达控制器104响应于激励指令Ca并根据输入电能PI的所感测到的电流和用户定义的电流设定点向马达16供应电能。
马达控制器104包括驱动器控制器106和马达驱动器116。驱动器控制器106控制从***电能输入102向马达驱动器116供应的电能。驱动器控制器106是基于微处理器的装置，其经由逻辑电能供应部108接收来自输入电能PI的电能，并且经由单独数字输入110接收来自润滑控制器42的致动指令Ca。单独数字输入110为仅数据连接，润滑控制器42通过其向马达16提供开动指令和关停指令。驱动器控制器106接收来自电流传感器112的所感测到的电流信号Cs，电流传感器112布置在***电能输入102与马达驱动器116之间。所感测到的电流信号Cs反映接收自***电能输入102的瞬时电流，其可以根据***操作、环境和电源的变化而随时间变化。驱动器控制器106进一步接收来自用户输入装置114的用户输入电流信号Cui，用户输入装置114例如可能是拨盘、旋钮或按键。用户输入电流信号Cui反映由人类用户所指定的用户定义的电流设定点。用户可以根据操作条件改变用户输入电流信号Cui。润滑***10的环境温度和/或湿度的变化例如能影响润滑剂粘度，从而必须对马达驱动器电能做出对应改变。
驱动器控制器106能例如是运行比例-积分-微分(PID)回路的基于微处理器的装置，所述PID回路根据所感测到的电流Cs和用户输入电流Cui生成脉冲宽度调制马达控制信号Cm。在替代实施例中，驱动器控制器106能运行另一种比例回路，诸如比例积分(PI)或比例微分(PD)回路。逻辑电能供应部108向驱动器控制器106提供连续电能，而不管润滑控制器42的控制状态。激励指令Ca独立于输入电能PI，并且支配马达控制信号Cm是否允许向马达16输送电能。
马达控制信号Cm调制来自***电能输入部102的输入电能PI，以获得与经由用户输入装置114设置的用户定义的电流设定点Cui大体相匹配的泵电流。以该方式，驱动器控制器106朝向用户指定的设定点连续地控制马达驱动器电能，无论何时润滑控制器42指定泵18应工作。
