Abstract
The utility model discloses a kind of constant pressure water supply system, between two valves on water main, pressure pump and hydraulic pressure sensor are installed, described hydraulic pressure sensor sends hydraulic signal to PLC, hydraulic signal and setting value contrast by PLC, output signal controls the output of frequency converter, described frequency converter is connected with pressure pump, controls the rotating speed of pressure pump.This device frequency converter controls pressure pump, achieves the constant pressure water supply of water main, effectively reduces the power consumption of pressure pump further; When decreasing without water source simultaneously, the damage of pressure pump idle running to its parts.After tested, after using the utility model, the power consumption of pressure pump saves about 40% than original.
Description
Technical field
The utility model relates to water supply field, specifically a kind of constant pressure water supply system.
Background technology
At present, insufficient water often in development zone, situation low during height during hydraulic pressure, often causes workshop water to have some setbacks, for people often adopts the method and increase hydraulic pressure of installing pressure pump between on water main two valves, but because pressure pump is daily without special messenger's monitoring management constantly, when pressure of supply water is normal, pump also leaves as usual, and on-site hydraulic pressure can be caused too high and pipeline breaking, when pipeline is anhydrous, water pump also runs well, sealing ring can be caused to burn out, also result in electricity consumption waste simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of constant pressure water supply system, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of constant pressure water supply system, between two valves on water main, pressure pump and hydraulic pressure sensor are installed, described hydraulic pressure sensor sends hydraulic signal to PLC, hydraulic signal and setting value contrast by PLC, output signal controls the output of frequency converter, described frequency converter is connected with pressure pump, controls the rotating speed of pressure pump.
As further program of the utility model: described PLC is also connected with touch-screen.
Compared with prior art, the beneficial effects of the utility model are: this device frequency converter controls pressure pump, achieves the constant pressure water supply of water main, effectively reduces the power consumption of pressure pump further; When decreasing without water source simultaneously, the damage of pressure pump idle running to its parts.After tested, after using the utility model, the power consumption of pressure pump saves about 40% than original.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of constant pressure water supply system.
Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1, a kind of constant pressure water supply system, between two valves 2 on water main 1, pressure pump 3 and hydraulic pressure sensor 7 are installed, described hydraulic pressure sensor 7 sends hydraulic signal to PLC 5, hydraulic signal and setting value contrast by PLC 5, and output signal controls the output of frequency converter 4, and described frequency converter 4 is connected with pressure pump 3, the rotating speed of pressure pump 3 is controlled, and then reaches constant pressure water supply; In addition, PLC 5 also carries out timing by frequency converter 4 pairs of pressure pumps 3 and controls switching on and shutting down and anhydrous shutdown, and effectively reduce the power consumption of pressure pump 3 further, when decreasing without water source, pressure pump 3 dallies to the damage of its parts simultaneously.After tested, after using the utility model, the power consumption of pressure pump 3 saves about 40% than original.As further scheme, described PLC 5 is also connected with touch-screen 6, for programming to PLC 5.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
