Abstract

一种混凝土喷射机速凝剂泵无介质运转保护装置,主要是于速凝剂泵入口管路上设有流量开关,且该流量开关与混凝土喷射机的PLC控制器相连接。由于流量开关的增设,在混凝土喷射机速凝剂泵工作时,可将速凝剂泵入口管路中有无介质(速凝剂)的信号发送给PLC控制器而进行相应动作,防止速凝剂泵空转。

Description

混凝土喷射机速凝剂泵无介质运转保护装置
技术领域
本实用新型涉及混凝土喷射机,尤其是涉及一种可防止混凝土喷射机速凝剂泵空转运行的保护装置。
背景技术
目前,混凝土喷射机速凝剂泵工作时无流量介质(速凝剂)检测,所以在速凝剂泵入口管路中无速凝剂的情况下会造成速凝剂泵空转。从而导致速凝剂泵的损坏或缩短使用寿命。
发明内容
本实用新型所要解决的技术问题是,针对上述现有技术不足,提供一种混凝土喷射机速凝剂泵无介质运转保护装置,可对速凝剂泵入口管路中有无速凝剂进行检测,以防速凝剂泵空转。
为解决上述技术问题,本实用新型所采用的技术方案是:一种混凝土喷射机速凝剂泵无介质运转保护装置,该装置包括与电液比例阀相连接的PLC控制器,其特点是,还包括流量开关,该流量开关设于所述速凝剂泵的入口管路上,且该流量开关与该PLC控制器相连接。
与现有技术相比,本实用新型的有益效果是:由于速凝剂泵的入口管路上设有流量开关,在混凝土喷射机速凝剂泵工作时,可将速凝剂泵入口管路中有无介质(速凝剂)的信号发送给PLC控制器而进行相应动作,从而,可对速凝剂泵入口管路中有无介质及时进行检测,以防止速凝剂泵空转。
附图说明
    图1是本实用新型的结构框图。
具体实施方式
参见图1,本实用新型为一种混凝土喷射机速凝剂泵无介质运转保护装置,其包括流量开关1,该流量开关1设于该速凝剂泵的入口管路(图中未示)上,且该流量开关1与该混凝土喷射机的PLC控制器2相连接,该PLC控制器2与电液比例阀3相连接。
加装流量开关1后,可利用流量开关1做为信号源,检测速凝剂泵入口管路中有无介质(速凝剂)。当无介质流动时,流量开关1则发出信号给PLC控制器2,PLC控制器2关闭模拟量(0-10VDC)的输出,电液比例阀3断电,从而使得液压马达驱动的速凝剂泵停止运转,达到防止速凝剂泵空转的目的。

Claims (1)

1.一种混凝土喷射机速凝剂泵无介质运转保护装置,该装置包括与电液比例阀(3)相连接的PLC控制器(2),其特征在于,还包括流量开关(1),该流量开关(1)设于所述速凝剂泵的入口管路上,且该流量开关(1)与该PLC控制器(2)相连接。
