Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, vertical single-stage single-suction centrifugal, it comprises: the pump housing 1, it has a S shape intake tunnel and the impeller for installing impeller installs cavity, the left side that described impeller installs cavity is provided with water flowing out structure, the outlet end wall of described water flowing out structure and intake tunnel are provided with plug 5, and 18; Be installed on the impeller 4 that impeller installs cavity, it is connected by flat key structure 17 with the pump shaft driven by motor 9, described motor is by bolt 10, nut 11, spring pad 12 and be arranged on above the pump housing, be provided with O shape between the described pump housing and pump cover and enclose 14, described impeller has nut 2, the spring pad 3 itself and pump shaft fixed, described impeller is installed cavity top and is provided with pump cover 15, this pump cover is by stud 6, spring pad 7, nut 8 and be installed on the pump housing, the pump shaft being positioned at pump cover place is provided with mechanical seal 16, and described pump cover place is provided with outlet valve 13.
Described pump body is provided with pressure transducer, it is connected to singlechip controller, and this singlechip controller is connected to outlet valve, and this outlet valve can select the outlet valve of Non-follow control, also can adopt the outlet valve of electrical control, the outlet valve such as controlled by singlechip controller then selects solenoid valve class.
After centrifugal pump starts, the impeller of High Rotation Speed drives interlobate liquid to rotate together.Under the influence of centrifugal force, liquid outwards moves from impeller along interlobate runner, is thrown out of from the end of impeller, and enter in spiral pump case, now flow velocity is higher, can reach 15 ~ 25m/s, increase kinetic energy; Meanwhile, due to the centrifugal force of liquid self, the static energy of liquid is also improved.After liquid enters pump case, because the Flow area in volute shaped pump casing expands gradually, the flow velocity of liquid reduces gradually, by part kinetic transformation be rest energy to pump discharge place, improving further of liquid, finally discharges from discharge tube.Meanwhile, because the liquid of impeller central is thrown out of, and define low pressure area, cause the pressure difference of barometric pressure (or suction eye) in pond on liquid level and impeller central place parital vacuum.Under the effect of this pressure difference, liquid just successively enters impeller along suction line, to supplement the liquid be discharged.Impeller ceaselessly rotates, and liquid just continuously sucks and discharges.
In sum, the working principle of single stage single suction volute pump is, is full of impeller High Rotation Speed in pump case of liquid, makes liquid be subject to the effect of centrifugal force, and power is changed into kinetic energy and static energy passes to liquid, thus is sucked by liquid and discharge.HYL (W) pump is installed in pump house, linked by distance-transmission pressure gauge (or pressure gauge with electric contact, pressure transmitter etc.) and special control cabinet, distance-transmission pressure gauge (or pressure gauge with electric contact, pressure transmitter etc.) detects pressure in custom system and obtains height, when system pressure is lower than setting pressure, to be provided to professional control cabinet by Detecting element and open pump signal, special control cabinet starts water pump to system water supply supercharging; When pressure is higher than setting pressure, water pump quits work; Can realize when pump quantity >=2 automatically alternately, clock alternately, the function such as fault standby self-closing, automatically plus-minus pump; Automatically run by frequency-changing control system constant voltage, do not need special messenger's unmanned.
The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned mode of execution, and every technological scheme belonging to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, the some improvement carried out under the prerequisite not departing from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
