Abstract
The invention relates to a device for controlling a water well water pump of a tap water supply system through a central PLC. The device is composed of a PLC programmable controller 1 and a frequency converter 2. The device has the advantages that the soft start, movement and soft stop of the water pump are achieved, and the water pump is protected.
Description
Technical field
The present invention relates to the control appliance of the well water pump of the tap water supply system that a kind of central PLC controls.
Background technology
Along with the development of small towns, county's economic construction, the further expansion of city size, the existing well of part water factory and high-level reservoir can not meet the growing demand of people's lives, need expand water supply capacity, newly-increased water head site, needs to carry out centralized Control to water head site and reservoir simultaneously.
Summary of the invention
The control appliance of the well water pump of the tap water supply system that the object of the present invention is to provide a kind of central PLC to control, what purport realized water pump softly only starts shipment dynamic, soft stop, plays the protective effect to water pump.For achieving the above object, the technical solution used in the present invention is
:the present invention relates to the control appliance of the well water pump of the control appliance of the well water pump of the tap water supply system that a kind of central PLC controls
,be made up of PLC 1, frequency converter 2, it is characterized in that the frequency converter 2 of the control appliance of the well water pump of the control appliance of the well water pump of the tap water supply system that described a kind of central PLC controls obtains the control signal of PLC by communication mode, drag well water pump according to the requirement of PLC, supply water to reservoir.
advantage of the present invention:
What realize water pump softly only starts shipment dynamic, soft stop, plays the protective effect to water pump.
detailed description of the invention explanation
fig. 1 is system composition schematic diagram:
1-PLC 2-frequency converter.
tell about below in conjunction with Fig. 1the control appliance of the well water pump of the tap water supply system that a kind of central PLC controls
operating principle:
The present invention relates to the control appliance of the well water pump of the control appliance of the well water pump of the tap water supply system that a kind of central PLC controls
,be made up of PLC 1, frequency converter 2, it is characterized in that the frequency converter 2 of the control appliance of the well water pump of the control appliance of the well water pump of the tap water supply system that described a kind of central PLC controls obtains the control signal of PLC by communication mode, drag well water pump according to the requirement of PLC, supply water to reservoir.The information such as output voltage, electric current, rotating speed, fault of frequency converter 2 is sent to PLC by communication mode, and what frequency converter can realize water pump softly only starts shipment dynamic, soft stop, plays the protective effect to water pump.
