Example one
As shown in fig. 1, the embodiment of the present invention provides a negative pressure water intake device, including: a water intake pipe 001, a drainage tank 002 and a water intake pump 003;
the water intake pipe 001 is in fluid communication with the top of the drainage tank 002;
the water intake pump 003 is in fluid communication with the bottom of the drainage tank 002.
Specifically, drainage jar 002 can store water to ensure that the hydroenergy of drainage jar 002 bottom can flow in the water intaking pump 003, and then water backward flow when avoiding the water intaking pump 003 to close, ensure from this that the water intaking pump 003 is started the in-process repeatedly all the time by the injected water, and then prevent that the water intaking pump 003 from damaging because of the idle running. When water is taken, the water taking pump 003 is started to suck the water at the bottom of the drainage tank 002 and discharge the water through the water taking pump 003, the internal air pressure of the drainage tank 002 is reduced, and the water enters the drainage tank 002 through the water taking pipe 001 under the action of the external atmospheric pressure; when the water intake pump 003 is turned off, water remains in the bottom of the drainage tank 002, and the water in the drainage tank 002 can be injected into the water intake pump 003, thereby avoiding idling when the water intake pump 003 is restarted.
Further, in the embodiment of the present invention, the water intake pipe 001 is communicated with the water source 010;
from the end of connecting water source 010 to the end of connecting drainage jar 002, intake pipe 001 communicates from bottom to top.
Specifically, negative pressure water intake device is particularly useful for getting water from bottom to top, and when water intake pump 003 was started, water in the water source 010 flowed and got into drainage jar 002 along water intaking pipe 001 from bottom to top, and the water that gets into in the drainage jar 002 can amass in drainage jar 002, and the water in the drainage jar 002 can discharge through water intake pump 003 under water intake pump 003's effect.
In the case of lack of the drainage tank 002, the water pump 003 needs to be used to pump water from bottom to top, and the water pump 003 is prevented from idling by injecting water into the pump body and the pipeline. The negative pressure water intaking device that this embodiment provided passes through the drainage jar 002 retaining to ensure that the inlet channel of water intaking pump 003 fills water all the time, and then can avoid water intaking pump 003 to produce idle running, and alleviated the technical problem who slows down water intaking efficiency because of sneaking into a large amount of bubbles in the inlet channel of water intaking pump 003.
In the negative pressure water intake device provided in this embodiment, the position of the water intake pump 003 is higher than the water surface of the water source 010. Through drainage jar 002 retaining, when the water intaking pump 003 stop work, the water in the drainage jar 002 can be poured into the water intaking pump 003 to avoid the water among the water intaking pump 003 to flow back to the water source 010.
Further, the water intake pump 003 is positioned lower than the water surface in the drainage tank 002.
When the water intaking pump 003 shuts down, the water in the drainage jar 002 is automatic under the action of gravity to be poured into the water intaking pump 003 into to ensure that the inlet channel of the water intaking pump 003 is full of water all the time, and then avoid the water intaking pump 003 to produce idle running when starting.
Further, the negative pressure water intake device further comprises a water injection pipe 004, and the water injection pipe 004 is in fluid communication with the top of the drainage tank 002.
During the water intaking, under water intaking pump 003 closed condition, can be earlier through water injection pipe 004 water injection to drainage jar 002, the rivers that get into in the drainage jar 002 go into the inlet tube of water intaking pump 003 to produce idle running when avoiding water intaking pump 003 to start.
In addition, the water injection pipe 004 is installed with the first valve 005. After injecting a certain amount of water into drainage tank 002 through water injection pipe 004, close first valve 005 to outside air gets into drainage tank 002 through water injection pipe 004 when avoiding getting water pump 003 to start.
Further, negative pressure water intaking device still includes blast pipe 006, blast pipe 006 and drainage jar 002's top fluid intercommunication.
Under water intaking pump 003 closed condition, through water injection pipe 004 water injection in to drainage jar 002, the air pressure increase in drainage jar 002 to the gas in the drainage jar 002 can be discharged through blast pipe 006.
Further, second valve 007 is installed to blast pipe 006, treats that when water injection is accomplished in drainage jar 002, first valve 005 and second valve 007 should all be closed, start water intaking pump 003 to can inhale water intaking pump 003 through drainage jar 002 with the water of water source 010 in.
Further, negative pressure water intaking device still includes overflow pipe 008, overflow pipe 008 and drainage jar 002 fluid intercommunication.
Specifically, the overflow pipe 008 is installed at a preset height position of the drainage tank 002, and when the drainage tank 002 stores water to a preset height, the water in the drainage tank 002 can be discharged through the overflow pipe 008.
It should be noted that the overflow pipe 008 is provided with the third valve 009, when water is discharged through the overflow pipe 008, the first valve 005, the second valve 007 and the third valve 009 are all closed, and at this time, the drainage tank 002 contains a sufficient amount of water, so as to ensure that the water inlet pipe of the water intake pump 003 is filled with water, and at this time, the water intake pump 003 is started to avoid the idle rotation problem.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
