Description

喷洒器过热保护
技术领域
本申请要求于2004年元月2日提出申请的申请系列号为60/534,180的美国专利的权利。
背景技术
电动无空气喷漆器很普遍得应用在将建筑涂料施加至不同结构上。此类喷洒器典型地使用开/关(静区)或者变速控制，以保持设定压力。典型地，在此类喷洒器上提供过热保护，当马达的温度超过预定程度时所述过热保护关闭所述喷洒器。
发明内容
从而本发明的目标是提供一种为喷漆器提供增强性能的过热保护系统。提供保护以允许使用更小和/或更轻的马达同时保持可接受的性能级别也是本发明的目标。
为达到该目标，在所述喷洒器中电动马达的刷座上放置一个100千欧的NTC热敏电阻器，以监测所述喷洒器的温度。控制板上的处理器监测所述热敏电阻器输出。在温度充分低于所述马达的极限时，所述喷洒器以完全的选定压力变速运行以获得最优性能。
在所述温度接近允许的极限时，能采用几种性能削减以防止过热。优选的方式是逐步降低控制压力。如果所述温度持续升高，所述控制器转换至开/关或静区控制。这种模式使用小喷嘴尖冷却得更好，这是因为风扇转速更高且有相当长的关闭时间。如果温度不受这些措施的影响而继续升高，所述控制器关闭所述单元。
对所述系统额外增强的是，控制逻辑的控制需要依照所述马达运行时产生的不同的断路温度。例如，如果开/关操作的断路点为140℃，所述控制则仅会在超过该温度达到马达运行一分钟时间后改变到开/关模式。这有助于补偿在所述马达停止后所述热敏电阻器监测到的马达温度继续升高一些的事实。
通过以下结合附图所做的说明，可更充分体现本发明的这些及其它目标与优势，其中几个视图中相同的参考符号指代相同或相似零件。
附图说明
图1为表示当前发明的示意图。
具体实施方式
如图1所示，100千欧NTC热敏电阻器10放置在喷洒器16中电动马达14的刷座12中，以监测喷洒器16的温度。控制板20上的处理器18监测热敏电阻器10的输出。在温度充分低于马达14的极限时，喷洒器16以完全的选定压力变速运行以获得最优性能。
在所述温度接近允许的极限时，能采用几种性能削减以防止过热。优选的方式是逐步降低控制压力。如果所述温度持续升高，控制器20转换至开/关或静区控制。这种模式使用小喷嘴尖冷却得更好，这是因为风扇转速(马达内)更高且有相当长的关闭时间。如果温度不受这些措施影响而继续升高，控制器20关闭所述单元。
对所述系统额外增强的是，控制逻辑的控制需要依照马达14运行时发生的不同的断路温度。例如，如果开/关操作的断路点为140℃，控制器20则仅会在超过该温度达到马达运行时间一分钟后改变到开/关模式。这有助于补偿在所述马达停止后所述热敏电阻器监测到的马达温度将继续升高一些的事实。
在不偏离由权利要求所确定的本发明的精神和范围的情况下，可对本发明的过热保护系统进行各种的修改和变化。
