Description
[technical field]
The utility model belongs to water technical field on centrifugal pump, particularly a kind of centrifugal water pump without bottom valve water-supply apparatus.
[background technique]
Water pump a kind ofly carries fluid or increase the machinery of hydrodynamic pressure, is generally adopt centrifugation to improve fluid rotating speed, reaches the speed improved when fluid leaves impeller; Wherein, have a current chamber in the pump case of centrifugal water pump, impeller needs to rotate in the current chamber being full of liquid, and centrifugal water pump just can be made fast to liquid pressing.Therefore, at water pump before activation, must make to be full of water in the current chamber between pump case and rotor, then starting electrical machinery, makes pump shaft impeller and liquid do high speed rotary motion, liquid generation centrifugal motion, be thrown toward impeller outer edge, the outlet flow through volute pump case flows into the setting-out pipeline of water pump.
As shown in Figure 1, in prior art, centrifugal water pump has bottom valve water-supply apparatus planimetric map, Problems existing mainly:, there is water leakage phenomenon in bottom valve bad sealing, often keep in repair, impact produce normally.
[model utility content]
The purpose of this utility model is to provide a kind of centrifugal water pump without bottom valve water-supply apparatus, and can solve centrifugal water pump bottom valve and be not closed completely that start can not the problem of normal pumping, it is simple that this arranges structure, and efficiency of drawing water is high, easy to use.
The utility model is achieved through the following technical solutions:
A kind of centrifugal water pump without bottom valve water-supply apparatus, comprises intake pipe, motor, centrifugal water pump and Siphon pot; Described intake pipe one end is arranged in pond, and the other end is arranged in Siphon pot, and the intake pipe one end in Siphon pot exceeds bottom Siphon pot and arranges; Described Siphon pot is arranged in support platform, and be communicated with centrifugal water pump water intake bottom Siphon pot, top is provided with water filling hole; Described centrifugal water pump is driven by motor.
Described intake pipe one end height in Siphon pot is greater than 1/2 ~ 2/3 of Siphon pot height.
Described Siphon pot top is installed with for the first emptying ball valve of overflow, and bottom is installed with the second ball valve for unwatering in winter.
Also comprise and being flexible coupling, described centrifugal water pump is flexible coupling by Flange joint, is flexible coupling to connect Siphon pot by pipeline.
One end that described intake pipe is arranged in pond is provided with filter screen.
Described centrifugal water pump outlet pipe connects the 3rd ball valve of regulating water flow size, the 3rd ball valve connects power failure pressurize safety check, safety check, by the waterpipe of Flange joint, installs the pressure gauge of display hydraulic pressure size above pipeline.
Compared with prior art, the utility model has following useful technique effect:
The centrifugal pump without bottom valve water-supply apparatus that the utility model patent uses adopts siphon principle, according to different model centrifugal lift of pump bore, inhale journey bore, the supporting closed water storage tank of uninterrupted making, according to physics siphonage, water is sent into centrifugal pump blower inlet casing endlessly.Adopt that this equipment normally can run when without bottom valve, zero failure, overcome use bottom valve because water is dirty, phenomenon that the bad sealing, the often maintenance that cause containing reasons such as assorted, corrosion, impact are produced, thoroughly solve water problems on centrifugal water pump.Reduce amount of maintenance in process of production, meet continuous prodution, processing ease, easy.The normal operation of water pump can be guaranteed, do not occur phenomenon of cutting off the water supply.The potential safety hazard that the safe handling of equipment and stopping using etc. brings thoroughly is stopped, the leakage of inflammable liquid caused of cutting off the water suddenly can not be there is in running, environmentally safely play guaranteeing role.
Further, the utility model adopts the vibrations be flexible coupling when can reduce centrifugal water pump work.
Further, being provided with of filter screen helps filter impurities in water, ensure that the operating life of centrifugal water pump.
Further, Siphon pot bottom is installed with the second ball valve for unwatering in winter, effectively placed the situation of freezing water, the work of icing effect device winter.
[accompanying drawing explanation]
