基于扬程的水泵运行失效PLC监控系统设计
摘要：机械水泵是一种能传送和加压液体的机器。也是这个社会普遍而又通用的耗电量较大的设备。水泵所
需要测试的性能数据主要是流量参数、吸力参数、扬程参数、轴功率参数、水功率参数和效率参数等。它主要运用在
了我国的农业和现代化工业建设中，这里我主要研究了地暖的循环泵，这样的泵通常是指循环液体泵的输送过程中
的反应、吸收和分离、释放和再生。它的大部分工作都是在一层使用单级离心泵。如果这个泵工作环境稳定的话，地
暖循环泵的流量大小中等，而且平均地面加热循环泵的流量相对较低。他的扬程也是又小又低的，因此可以实现循环
泵的压力降。而本设计报告主要就是要解决水泵冷热水的运输、扬程和运行失效的问题。该课题的控制器选用了西门
子系列的 PLC 进行控制；水泵冷热水的控制选用了温度传感器来进行控制；水泵扬程的控制选用了压力变送器进行
控制；最后选用了的昆仑通态触摸屏进行人机控制。本方案主打的是控制。
关键词：泵、PLC、变送器、传感器、触摸屏。
Design of pump operation failure monitoring system based on
head
A water pump is a machine that can carry and pressurize liquids. It is also a common and universal equipment with larg
e power consumption in today's society. Pump performance parameters are flow, suction, lift, shaft power, water power, effi
ciency and so on. It is mainly used in China's agricultural and modern industrial construction, here I mainly studied the floor
heating circulation pump, the circulation pump generally refers to the device in the transmission reaction, absorption, separ
ation, absorption and regeneration of circulating liquid pump. Most of its work is the use of singlestage centrifugal pump. Floor heating circulation pump flow of medium size, if it in stable working conditions, the pump flo
w is relatively small. Its head is also small and low, so the circulating pump pressure drop can be achieved. And this design re
port is mainly to solve the problem of cold and hot water pump transportation, lift and operation failure. The subject of the
controller selected Siemens series PLC for control; The water pump cold and hot water control USES the temperature sensor
to carry on the control; The pressure transmitter is used to control the pump head. Finally, kunlun tongtai touch screen is se
lected for man-machine control. This program focuses on control.
Key words: pump, PLC, transmitter, sensor, touch screen.
