Abstract
The invention discloses a variable frequency and constant pressure water supply device of a water tank. The device comprises a gas pressure water tank, a water pump set, a water storage tank, a pressure detecting system and a variable frequency electrical cabinet. The variable frequency and constant pressure water supply device of the water tank disclosed by the invention solves the problems that traditional water supply devices are big in size and large in occupied space, and are needed to be aerated after being used for a period; constant pressure and variable frequency water supply is realized, a net pipe pressure adjusting function is available, the pressure at any water consuming point can be constant, and the designing mechanism is reasonable.
Description
Technical field
The present invention relates to feedwater supply equipment, specifically belong to a kind of water tank constant pressure water supply device.
Background technology
Frequency control constant pressure water compensation apparatus, being grow up on the basis of traditional Constant pressure tank, is the combination of variable-frequency control technique and expansion tank technology.Its general principle is the water pressure change of the system according to sensor collection, adjusts supply frequency, smoothly infinitely adjust small pump rotating speed, namely regulate rate of water make-up, to reach the object realizing system constant pressure point pressure relative constancy by logical calculated.
Summary of the invention
The object of this invention is to provide a kind of water tank constant pressure water supply device, solve traditional water supply device, volume is large, take up an area large, often by the problem also must inflated after a period of time, achieve constant-pressure variable and supply water, and there is webmaster pressure adjusting function, can constant arbitrary water spot pressure, design organization is reasonable.
The technical solution used in the present invention is as follows:
A kind of water tank constant pressure water supply device, comprises water pump group, auto-pneumatic cylinder, water storage tank, pressure detecting system and frequency conversion Electric Appliance Cabinet.
Described water pump component is main pump group, auxiliary pump group and stand by pump group.
Described water pump group exit of pump is equipped with the electro connecting pressure gauge and pressure transmitter that can do overpressure protection, and the signal of described pressure transmitter feedback is to PLC.
The tank diameter of described auto-pneumatic cylinder is 600mm-1200mm.
Described water storage tank top is provided with breather, manhole, and the upper plate of water tank is provided with overfall, and bottom is provided with sewage draining exit.
Described frequency conversion Electric Appliance Cabinet adopts the PLC of Siemens 6RA40 series converter plant and Siemens S7300 and carries out data display by wincc touch-screen, Stress control error≤0.01Mpa, and touch-screen display precision is 0.01Mpa.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention feeds back to plc(programmable logic controller by detected pressures), plc by the signal transacting collected and export analog signals to frequency converter to regulate water pump group run to realize constant pressure.There is the function of disturbance rejection and saturation integral.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
See accompanying drawing, a kind of water tank constant pressure water supply device, comprises water pump group 5, auto-pneumatic cylinder 1, water storage tank 6, pressure detecting system 3 and frequency conversion Electric Appliance Cabinet 7.Described water pump group 5 is divided into main pump group, auxiliary pump group and stand by pump group.Described water pump group exit of pump is equipped with pressure transmitter 4 and feeds back signal to PLC.Described water pump group 5 exit of pump is equipped with the electro connecting pressure gauge 2 that can do overpressure protection.The tank diameter of described auto-pneumatic cylinder 1 is 600mm-1200mm.When user's water demand time, the pressure transmitter 4 of pump outlet tube feeds back signal to plc, regulates water pump to be pressurized to setting pressure constant pressure water supply or the constant-pressure variable water supply of user institute water requirement.When pump outlet pressure transmitter 4 breaks down, electro connecting pressure gauge 2 does overpressure protection action, guarantees that user's pipe network is not damaged.
