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 and 2, the integrated vacuum water diversion device and backwashing structure for a large-caliber water pump comprises a water pump 10, wherein a main outlet is arranged on the water pump 10, the main outlet is a normal water outlet of the water pump, and an outlet valve 11 is arranged at the main outlet. 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 the scheme, a vacuum water diversion route and a back flush route are arranged at the auxiliary outlet of the water suction pump 10.
Specifically, an auxiliary outlet of the water pump 10 is sequentially connected with the filtering mechanism, the electric valve 12, the vacuum tank 15, an inlet of the vacuum pump 18, an outlet of the vacuum pump 18 and the circulating water tank 17 to form a vacuum water diversion route. When the vacuum pump works, the vacuum pump 18 generates pumping separation on the real pump tank 15 to form negative pressure; meanwhile, high-pressure air is formed in the circulating water tank 17 to store energy.
The circulating water tank 17 is directly connected with the inlet of the vacuum pump 18 through a branch pipe, and a switch valve C20 is arranged on the branch pipe; the circulating water tank 17, the switch valve C20, the inlet of the vacuum pump 18, the vacuum tank 15, the electric valve 12 and the filter mechanism form a back flushing route. During back flushing, high-pressure air in the circulating water tank 17 directly enters the branch pipe and flows out from the inlet of the vacuum pump 18, and back flushing is performed on the filtering mechanism after passing through the vacuum tank 15 and the electric valve 12, so that impurities are prevented from being generated.
In the circulation tank 17, a lower water chamber and an upper air chamber are included. The air cavity is connected with the inlet of the vacuum pump 18 through a branch pipe and a switch valve C20; meanwhile, the air cavity is communicated with the outside through an air pipe, and a switch valve D is arranged on the air pipe. The water cavity is communicated with the outside through a water pipe.
In the scheme, a pipeline connecting the vacuum tank 15 and the inlet of the vacuum pump 18 is provided with a switch valve A, and a pipeline connecting the outlet of the vacuum pump 18 and the circulating water tank 17 is provided with a switch valve B.
When the vacuum water diversion work is carried out, the outlet valve 11 is closed, the electric valve 12 is opened, the switch valve A is opened, the switch valve B is opened, the switch valve C20 is closed, and the hanging valve D is closed, the vacuum tank 15 is pumped out to form negative pressure, water in a water source enters the auxiliary outlet through the water pipe and the pump cavity, and therefore 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.
When the backwashing work is carried out, the switch valve B is closed, the switch valve C20 is opened, the switch valve A is opened, the electric valve 12 is opened, the high-pressure air in the air cavity is used for backwashing the filtering mechanism, and the blockage is avoided.
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.
