Fig. 2 is the pipeline connection diagram of another embodiment of Fig. 1 supply equipment.
Fig. 3 is the air pressure tank pipeline connection diagram that adopts the air supplying pump tonifying Qi.
The specific embodiment
Referring to Fig. 1, a kind of relay pressurizing type automatic water supply device of the present utility model is equipped with water pump assembly, air pressure tank 3, flap valve 2, connecting line and control instrument 11,12,13 and switch board 14.
Supporting three the same specification feed pumps 5,6,7 of water pump assembly, the water inlet manifold 1 of supply equipment joins through the water inlet of flap valve 2 with air pressure tank 3, the outlet pipeline 4 that connects on the delivery port of air pressure tank 3 is as the inlet pipeline of water pump assembly, joins with the inlet pipeline of three feed pumps 5,6,7 in the water pump assembly.
Also be connected an auxiliary water pump 8 and supporting inlet pipeline and outlet pipeline thereof between the water inlet manifold 1 of supply equipment and the outlet pipeline 4 of air pressure tank 3.The signal that switch board 14 is gathered according to control instrument 11,12,13 is implemented control to the operation of supply equipment.In order effectively to utilize the original pressure potential of municipal water sources, simultaneously also in order to adapt to significantly variable parameter operation of water pump, feed pump 5,6,7 all should adopt variable frequency regulating speed control.
Referring to Fig. 2, among another embodiment of this supply equipment, the water inlet of air pressure tank 3 also can be used as delivery port, and the intake-outlet of air pressure tank 3 is connected with the inlet pipeline 4 of water pump assembly on the one hand, joins through the water inlet manifold 1 of flap valve 2 with supply equipment on the other hand.
No matter shown in Fig. 1 or Fig. 2, the operation control method of this supply equipment is as follows:
The supply equipment of the normal operation of debugging; the hydraulic pressure that keeps user's pipe network 15 between down period by air pressure tank 3; when the air pressure tank energy storage is used consumption; make that supply equipment started operation automatically when user's pipe network 15 hydraulic pressure were reduced to the low pressure limit of setting, at first start auxilliary pump 8; this pump directly extracts municipal water sources; at original hydraulic pressure basis up-conversion speed governing operation, how much difference what replenishes to realize energy-saving run, satisfies constant pressure water supply demand in user's low discharge scope.If user's pipe network water supply volume increases; auxilliary pump 8 can not satisfy the demands; show as air pressure tank outlet pipeline 4 pressure and can not keep required constant voltage value; then start first feed pump 5 or 6 or 7 automatically; this is determined by program; auxilliary pump 8 is shut down, this feed pump frequency control operation, constant pressure water supply in the single-pump flow scope.If water supply volume continues to increase, a feed pump can not satisfy water requirements, then starts second feed pump 5 or 6 or 7 automatically, and this is determined by program, frequency control constant-pressure operation in parallel.If still can not satisfy water requirements, then start the 3rd feed pump 5 or 6 or 7 automatically, this is determined by program, frequency control constant-pressure operation in parallel.Because the operation of feed pump 5,6,7 is direct water source with air pressure tank 3, and has a certain amount of press water in the air pressure tank 3, therefore city planting ductwork there is certain cushioning effect.If user's pipe network 15 water supply volumes reduce, so that the feed pump running frequency is low excessively, then can subtract pump automatically, when reducing to last feed pump 5 or 6 or 7 (by the program decision), get back to again and keep varying speed and constant pressure feed water operation in the single-pump flow scope.If the less single feed pump running frequency that makes of flow is lower, at this moment can start auxilliary pump 8 automatically and give air pressure tank 3 water-filling superchargings, when air pressure tank 3 moisturizings are pressurized to the constant voltage desired value, automatically close last feed pump 5 or 6 or 7 (by the program decision), change and keep constant pressure water supply in the low discharge scope by auxilliary pump 8 frequency controls.At auxilliary pump 8 run durations; if user's pipe network 15 water supply volumes are reduced to very low or be 0 o'clock; supply equipment will enter stopping process automatically; that is: auxilliary pump 8 quickens operation until being pressurized to the upper pressure limit of setting for air pressure tank 3 water-fillings; auxilliary then pump 8 autostops; just supply equipment is shut down, and at this moment air pressure tank 3 plays the effect of shutting down pressurize.At feed pump 5,6,7 run durations, if during the minimum swabbing pressure that air pressure tank 3 outlet pressure allow smaller or equal to municipal water sources, supply equipment is forbidden operation with autostop, to avoid the excessive suction to municipal water sources.
Auxilliary pump 8 in this supply equipment can be governor impeller, and its flow should be less than feed pump, according to actual conditions can the feed pump metered flow 1/10～1/2 between select, its lift is then identical with feed pump, so more helps the energy-saving run of a complete set of equipment.
As shown in fig. 1, when air pressure tank 3 adopts automatic gas compensating type air pressure tank, auxilliary pump 8 also can doublely be done air supplying pump and use, at this moment auxilliary pump 8 is connected as shown in Figure 3 with the pipeline of air pressure tank 3, be serially connected with electric control valve 17 and flap valve 9 in the inlet pipeline of auxilliary pump 8, the water inlet of auxilliary pump 8 connects a branch line, and this branch line and tonifying Qi tube 16 join.
The operation control method of auxilliary pump 8 is as follows:
When low discharge moves, open electric control valve 17 automatically, as previously mentioned, auxilliary pump 8 is kept the low discharge running.When the needs tonifying Qi; close electric control valve 17, auxilliary pump 8 is the water source with tonifying Qi tube 16, and it is pumped into air pressure tank 3; in tonifying Qi tube 16, form negative pressure; outside air enters tonifying Qi tube 16 through cleaner 18, flap valve 19, and running time is controlled in time-delay, treats that tonifying Qi tube 16 advances sufficient air; auxilliary pump 8 is shut down; at this moment the press water refluence enters tonifying Qi tube 16 through auxilliary pump 8 in the air pressure tank 3, by the hydraulic equilibrium effect air in the tonifying Qi tube 16 is pressed into air pressure tank 3 through flap valve 20, so far finishes a tonifying Qi.
