背景技术Background technique

离心泵是利用叶轮旋转而使水发生离心运动来工作的。水泵在启动前,必须使泵壳和吸水管内充满水,然后启动电机,使泵轴带动叶轮和水做高速旋转运动,水发生离心运动,被甩向叶轮外缘,经蜗形泵壳的流道流入水泵的压水管路。因此离心泵在间隙工作时,常需要人工将泵壳和吸水管注满水,或将其内的空气抽出来,该种方式存在工作效率低下,不方便等缺陷。Centrifugal pumps work by rotating the impeller to cause the water to move centrifugally. Before starting the pump, the pump casing and the suction pipe must be filled with water, and then the motor is started to drive the impeller and the water to rotate at a high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, and flows through the volute pump casing. The pressure water pipeline flowing into the water pump. Therefore, when the centrifugal pump works in the gap, it is often necessary to manually fill the pump casing and the suction pipe with water, or to extract the air in it, which has the disadvantages of low working efficiency and inconvenience.

具体实施方式detailed description

下面结合附图及具体的实施例对发明进行进一步介绍:Below in conjunction with accompanying drawing and specific embodiment the invention is further introduced:

参考图1,本发明一种用在离心泵上的真空装置,包括离心泵、吸水管2和出水管3,在吸水管2上设置有止回阀4,在离心泵和止回阀4的吸水管2上设置有与真空泵8连接的抽气管7,抽气管7上设置有阀门6。With reference to Fig. 1, a kind of vacuum device used on the centrifugal pump of the present invention comprises a centrifugal pump, a water suction pipe 2 and a water outlet pipe 3, a check valve 4 is arranged on the water suction pipe 2, and a check valve 4 is arranged between the centrifugal pump and the check valve 4 The suction pipe 2 is provided with an air extraction pipe 7 connected with a vacuum pump 8 , and the air extraction pipe 7 is provided with a valve 6 .

作为本实施例的进一步,在所述吸水管2或出水管3上安装有流量计5,该流量计5的数据端口与PLC控制器连接,PLC控制器又分别与离心泵、阀门6的控制端口和真空泵8的控制端口连接。这样PLC控制器从离心泵获取其实时的工作参数,PLC控制器从流量计5获取流量监测数据,此时当离心泵还在工作时,且流量计5处传来的流量数值小于预设值时,PLC控制器控制阀门6打开,使出真空泵8开始工作,将泵壳和吸水管2内的空气抽出以便离心泵正常工作时。As a further step of the present embodiment, a flow meter 5 is installed on the water suction pipe 2 or the water outlet pipe 3, and the data port of the flow meter 5 is connected with the PLC controller, and the PLC controller is connected with the control of the centrifugal pump and the valve 6 respectively.
