By relevant parameters such as 1 set device operating pressures of frequency-conversion control cabinet before starting, when equipment is run, by pressure sensing
7 continuous acquisition water outlet ductwork pressure of device, and it is converted into the frequency-changing control system that electric signal is sent to frequency-conversion control cabinet 1,
The signal fed back is compared and operation by control system with the operating pressure of setting；
Add pump process: the water outlet ductwork pressure that system detection arrives is lower than setting pressure, then control system issues instruction and rises
High electric machine frequency, 1 Accelerating running of vertical multi-stage centrifugal pump, until vertical multi-stage centrifugal pump power frequency operation, system continues to examine at this time
Measuring pressure, if the pressure of system detection is still lower than setting pressure, which can be switched to work by control system
Frequency is run, and lower vertical multi-stage centrifugal pump 1 of variable frequency starting simultaneously, until water outlet ductwork pressure reaches setting pressure, this
When vertical multi-stage centrifugal pump be maintained at the frequency operation；

The vertical multi-stage centrifugal pump 1 started at first in vertical multi-stage centrifugal pump 1 is out of service, that is, reduces the fortune of vertical multi-stage centrifugal pump 1
Row number of units, until water outlet ductwork pressure is constant, main pump stops working, and auxiliary pump supplies water in setting pressure limit, supplies water
Mode is variable frequency water supply.
Using integrated Specialty Design, compact-sized, system is directly installed in water tank the utility model, can be subtracted in outdoor
The construction of few pump house, small investment is easy for installation, good appearance.Full-automatic intelligent can control, and have a variety of protections and control function,
All water materials of crossing of unattended boxization one pumping plant use 304 food-grade stainless steels, mating air pressure tank and water-stop material
Material meets sanitary standard, can avoid the various pollution of waterhead problems of conventional sinks.It is fastened inside water tank using net like lacing wire, resistance to compression
By force；It is stable, with small vibration, low noise (level of noise is lower than 60 decibels).Vertical multi-stage centrifugal pump is vertical using light-duty stainless steel
Centrifugal multistage pump multiple centrifugal pump, compared with the previous vertical multi-stage centrifugal pump noise, lower noise 20%~30%.Appearance beauty, if putting
In the rhetoric of outdoor slightly some this plants of Teng, one jiao of beautiful landscape can be increased to cell.Its internal control equipment uses
The frequency converter of state-of-the-art electrical ABB AB of group outlet the biggest in the world international at present.The system not only has outstanding transmission
Characteristic, and have powerful application software, combine with a programmable controller (PLC), so that it may reach a variable frequency pump with it is more
The constant pressure water supply of platform constant displacement pump, its control section can save ID adjuster compared with control equipment in the past and each group switching contacts
Device greatly improves system reliability, stability, special good using simple, performance.The constant of pressure of supply water is kept, can make to supply water
And with keeping balancing between water, i.e., supply water when more with water also more, it supplies water when few with water also few, to improve the quality of water supply.
Vertical multi-stage centrifugal pump uses aluminum-shell motor, and rapid heat dissipation will not burn out equipment because of motor overheating；And it is set in control
Faulty alarm system, failure automatic switchover system overheat overload protective device, leak leakage protection system, the automatic inspection of timing
Repair alarm system, the powers such as no water conservation system.Box and pump integrated to be adjusted using PID closed loop, constant pressure precision is high, hydraulic pressure wave
It moves small.It is equipment operation, reliable with the various automatic protection functions such as overload, short circuit, overcurrent, be easy to use and.Automatic water supply
Equipment also has the function of that vertical multi-stage centrifugal pump operating etc. is automatically switched in water shortage termination of pumping, timing.Unattended box integration
Pumping plant can automatically control acceleration and deceleration speed according to actual feedback pressure, keep the pressure of unit more stable.Solve conventional control
There is the problem of pressure toning and in vertical multi-stage centrifugal pump switching or in the case where water occur and change greatly in equipment, pressure
Fluctuate bigger problem.Box and pump integrated man-machine interface is clear, easy to operate, and pipe network constant pressure protector is before negative-pressure balancing
It puts and possesses dual mechanically-sealing apparatus, even if a mechanically-sealing apparatus breaks down, another is enabled immediately, guarantees to set
The case where standby normal operation is not in leak.
According to drag characteristic, when flow is bigger, resistance is bigger.Overcome to there are enough lifts in big water consumption
Resistance, existing similar product only presses big flow institute when setting pressure substantially using Isobarically Control technology in the market
The pressure needed is arranged, and when small flow water, pressure surplus causes energy dissipation.Self-compensating pressure technology can according to
The setting pressure of the variation automatic adjustment of water, operates in low pressure values in small flow water, with the increase of water consumption, presses
According to hydraulic characteristic(s), the use pressure being gradually increased saves electric energy to limits.The operating point of vertical multi-stage centrifugal pump determines
Fractional energy savings and service life, technical staff possess vertical multi-stage centrifugal pump abundant and design and debugging, not only examine
The single machine performance for having considered vertical multi-stage centrifugal pump has also fully considered the performance in parallel of vertical multi-stage centrifugal pump, makes more rationally.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
