Detailed Description
The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.
As shown in fig. 1, a vacuum water diversion device for a large-caliber water pump comprises a water pump 10, wherein a main outlet is arranged on the water pump 10, and the main outlet is a normal water outlet of the water pump. The inlet of the water pump 10 is connected with the liquid level of the water source through a water pipe, when the height difference between the water source and the water pump 10 is large, no water exists in the water pipe and the pump cavity of the water pump 10, the water pump 10 idles when rotating, and water cannot be pumped, so that the water pipe and the pump cavity are filled with water manually.
In order to avoid artificial irrigation before starting, an auxiliary outlet is also arranged at the top of the water pump 10 and is connected with a vacuum tank 15 through an electric valve 12; an outlet valve 11 is also provided at the main outlet. When the vacuum pump works, the outlet valve 11 is closed, the electric valve 12 is opened, the vacuum tank 15 is pumped out to form negative pressure, and water in a water source enters the auxiliary outlet through the water pipe and the pump cavity, so that the water pipe and the pump cavity are filled with water; then the electric valve 12 is closed, the outlet valve 11 is opened, the water pump 10 is started, the water pump 10 cannot idle, and normal water pumping is achieved.
In the scheme, the upper part of the vacuum tank 15 is also connected with the inlet of a vacuum pump 18 through a switch valve A, and the vacuum pump 18 is used for pumping the vacuum tank 15 to form negative pressure; the outlet of the vacuum pump 18 is also connected to the circulation water tank 17. That is, the vacuum pump 18 pumps air in the vacuum tank 15 out into the circulation tank 17, and the circulation tank 17 communicates with the outside through a corresponding air pipe.
Because when the vacuum tank 15 is separated to form negative pressure, part of water inevitably enters the vacuum tank 15, the bottom of the vacuum tank 15 is provided with a one-way valve 16, and the one-way valve 16 is also connected with a circulating water tank 17; a normally open solenoid valve 14 is further provided on the upper portion of the vacuum tank 15, and the normally open solenoid valve 14 is closed when a negative pressure is formed. When water is pumped normally, the normally open electromagnetic valve 14 is opened, the air pressure in the vacuum tank 15 becomes normal, the water in the vacuum tank flows into the circulating water tank 17 through the one-way valve 16, and the circulating water tank 17 is also communicated with the outside through a corresponding water pipe.
In the scheme, the electric control box 19 is further included, the electric control box 19 is electrically connected with the water suction pump 10, the vacuum pump 18, the outlet valve 11, the electric valve 12, the normally open electromagnetic valve 14, the one-way valve 16, the switch valve A and the switch valve B, and the opening and closing of the corresponding parts are controlled through the electric control box 19.
In order to stop the vacuum pump 18 in time and avoid electric energy waste, an electric contact vacuum meter 13 is arranged on the upper part of the vacuum tank 15, and the electric contact vacuum meter 13 is also electrically connected with a control electric box 19. When the water diversion heights are different, correspondingly adjusting the display needle limit contact of the electric contact vacuum meter 13 so as to control the vacuum pump 18 to stop; excessive negative pressure generated when the water diversion height is low is avoided, and electric energy waste is avoided; and the insufficient negative pressure generated when the water diversion height is high is also avoided, so that the control is accurate.
In the present embodiment, the vacuum tank 15, the circulation water tank 17, the vacuum pump 18, and the control electric box 19 are collectively disposed on the base plate for centralized installation and easy maintenance.
