The invention discloses an anti-suction device for an overhead pump, which can reduce air suction and equipment idling. An oil storage tank is added between the oil guide pipe for connecting the overhead pump and the oil suction pipe for connecting the oil tank. The oil suction pipe is extended in the oil storage tank, and the oil storage area is formed between the oil suction pipe and the oil storage tank in the oil storage tank so as to make the oil storage area overhead. When the pump stops working, the oil in the pump chamber flows back to the oil diversion pipe and storage area, and forms a sealed chamber. When the top pump starts again, it can directly absorb oil, reduce air suction, reduce equipment idling, reduce energy consumption and reduce failure. Before the first start-up of the top pump, it can also guide the oil pipe, pump chamber and oil storage area to inject oil, reduce the air inhalation of the first start-up of the top pump, and protect the equipment. The radial cross-section area of the suction pipe is less than 1/2 of the radial cross-section area of the oil storage tank, which ensures that the oil storage capacity of the oil storage tank meets the need of the start-up of the top pump, and the oil in the tank is quickly absorbed after the top pump runs. The overhead pump anti suction device of the invention has simple structure and reliable use.
【技术实现步骤摘要】
可减少空气吸入和设备空转的顶置泵防吸空装置
本专利技术涉及一种防吸空的方法及装置,具体是一种可减少空气吸入和设备空转的顶置泵防吸空装置。
技术介绍
液压站又称液压泵站,电机带动油泵旋转,油泵从油箱中吸油后打油,将机械能转化为油的压力能,推动各种液压机械做功。油泵工作时,内腔形成真空,靠大气压力将工作介质油从吸油管中输送到泵体。由于顶置式油泵(顶置泵)高于油箱液面以上,当顶置泵长时间不工作时,管道中的油将回流到油箱内,在顶置泵再次启动时泵腔无法形成真空,造成顶置泵需要排空大量空气,出现这种情况后不仅容易发生气蚀、增加噪声,使工作油液容易变质,浪费能耗,严重时导致泵轴和螺杆机械接触而咬死,损坏设备。现有的顶置泵防吸空主要是通过增加回油泵或是单向阀实现,结构复杂,且不够稳定。
技术实现思路
本专利技术的目的在于,提供一种结构简单、稳定可靠、减少设备空转的顶置泵防吸空方法及装置。本专利技术可减少顶置泵再次启动时吸入空气,提高顶置泵使用寿命,减少使用故障,降低维护成本。本专利技术的技术方案:一种顶置泵防吸空方法,在用于连接顶置泵的导油管和连接油箱的吸油管之间增加储油筒,延伸设置在储油筒内的吸油管和储油筒之间构成储油区,当顶置泵停止工作时,泵腔内的油回流到导油管和储油筒的储油区内,并进行存储,确保导油管内及储油筒下部充满油,且油箱和储油筒之间形成密封空间,顶置泵再次启动时可以直接吸油,减少了空气的吸入。顶置泵第一次启动前,还可以向储油区和导油管注入油,油存储在导油管、储油区和泵腔内,储油区内油的液面高度不低于所述导油管的上壁,减少顶置泵第一次启动时空气的吸入量。一种顶置泵 ...
