Abstract
The utility model discloses water supplying equipment without low-frequency frequency conversion. The water supplying equipment without low-frequency frequency conversion comprises a water inlet tube (1), a check valve (4), a power cord (5), a water outlet tube (6), a frequency changer, a controlling box (7) and a water pump set. The water supplying equipment without low-frequency frequency conversion is characterized in that the water pump set comprises water pumps with different flow (8), a pressure probe (2) is arranged on the water outlet tube, the pressure probe is connected with the frequency changer inside the controlling box through a signal line (3), and the water pumps are connected with the controlling box through the power cord. According to the change of water voltage and water volume of the water outlet pipe, and through the controlling box and the frequency changer, the water supplying equipment without low-frequency frequency conversion automatically combines the water pumps with corresponding flows to supply water, the water pumps run at the best operating point in the frequency conversion state or the power frequency state, and the working efficiency and use ratio of the water pumps are close to 100 percent.
Description
Technical field
The utility model relates to a kind of supply equipment, especially a kind of be practically applicable to the highrise building secondary water-supply without the low frequency frequency-changing water supply device.
Background technology
Along with urbanization process is fast-developing, the cities and towns highrise building is on the increase, improving (water level) hydraulic pressure by water pump is one of necessary means that solves high-rise secondary water-supply, because the living water use index variation is large, water pressure fluctuations is large, for overcoming the changes in flow rate of water use peak and water low ebb, secondary water-supply all drags the water pump water supply of one group of same traffic with frequency converter at present, when the output of water supply volume greater than a water pump, just start second water pump, solve second output that water pump is unnecessary, just change the rotating speed of water pump with frequency converter, realize changing output; If the output of First water pump is only owed a small amount of some, changed so second water pump of rotating speed, operating efficiency is just very low, because the efficient of centrifugal water pump is by certain rotating speed, and certain lift, certain flow design, obtained the flow change although change pump rotary speed, supplying water does not highly become, and variation has just occured the operating point of water pump, especially water use peak one mistake, the variable frequency pump most time is in low discharge and supplies water, and operating efficiency is extremely low, often claims the low frequency running.
For guaranteeing to change the water supply height of water pump behind the rotating speed, all join the lift of water pump group very high.Ubiquity high-lift pump when water pump turns round in power frequency, the situation of low lift operation (not in the optimal working point operation), the problem of large flow overburden operation will appear in water pump.At the outlet pipe of water pump a gate valve is installed for addressing this problem all, is used for regulating the water flow of water pump, in order to overcome the extra-heavy problem of large flow, so not only waste electric energy but also waste equipment.Therefore develop a kind of pump lift of joining highly identical with water supply, and the frequency-changing water supply device that turns round without low frequency is necessary.
The utility model content
The purpose of this utility model is to overcome the prior art deficiency, provide a kind of and can prevent the running of water pump low frequency, can guarantee again stable water pressure without the low frequency frequency-changing water supply device, the purpose of this utility model realizes by following technical proposals: the utility model comprises water inlet pipe, one way valve, power line, outlet pipe, frequency converter, control cabinet, water pump group, it is characterized in that the water pump group is that the different water pump of flow forms, outlet pipe is provided with pressure probe, pressure probe links to each other with frequency converter in the control cabinet by holding wire, water pump with control case and link to each other by power line.
Described hydraulic pressure probe for electro connecting pressure gauge, distance-transmission pressure gauge, pressure transmitter or hydraulic pressure switch any one.
Water pump group of the present utility model is one group of water pump that the lift same traffic is different, and according to the variation of the outlet pipe water yield and hydraulic pressure, by control cabinet and frequency converter, the water pump of Automatic Combined corresponding discharge supplies water, namely water supply volume little, start little pump; Water supply volume is large, start large pump; And the water pump of Automatic Combined corresponding discharge supplies water to satisfy water demand.A small amount of changes in flow rate is finished constant pressure by frequency converter, that is: the frequency of large pump drops to the water pump optimum efficiency when on the low side, and frequency converter automatically switches to a less water pump and supplies water; When the output of little water pump can not satisfy water demand, frequency converter automatically switched to a larger water pump and supplies water; When many pumps combinatory water supply, the variation of water supply volume is the variation of water pump combination, and rotating speed does not have large variation, so not only solved the operation of high-lift pump low lift, and water pump all is that the operating efficiency utilization rate of water pump is near 100% in the optimal working point operation at frequency conversion state or power frequency state.From above-mentioned situation as can be known, the purpose of this utility model can realize.

Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the present invention includes one way valve 4, power line 5, outlet pipe 6, frequency converter, control cabinet 7, water pump group that water inlet pipe 1, two ends link to each other with outlet pipe with water pump respectively, it is characterized in that the water pump group is that the different water pump of uninterrupted 8 forms, concrete flow is decided according to the water situation.Outlet pipe is provided with pressure probe 2, described hydraulic pressure probe for electro connecting pressure gauge, distance-transmission pressure gauge, pressure transmitter or hydraulic pressure switch any one, the present embodiment is selected distance-transmission pressure gauge.Pressure probe links to each other with frequency converter in the control cabinet by holding wire 3, water pump with control case and link to each other by power line.
Claims (2)
1. one kind without the low frequency frequency-changing water supply device, comprise water inlet pipe (1), one way valve (4), power line (5), outlet pipe (6), frequency converter, control cabinet (7), water pump group, it is characterized in that: the water pump group is that the different water pump of flow (8) forms, outlet pipe is provided with pressure probe (2), pressure probe links to each other with frequency converter in the control cabinet by holding wire (3), water pump with control case and link to each other by power line.
