Detailed Description
Referring to fig. 1, the present embodiment includes a first booster pump 3 and a second booster pump 9 which are arranged in parallel, input ends of the first booster pump 3 and the second booster pump 9 are connected to a system air source 11, output ends of the first booster pump 3 and the second booster pump 9 are connected to a buffer air storage tank 5 and then output to an air inlet of a high-pressure air storage tank 8 through a three-way switching valve 4, an air outlet of the high-pressure air storage tank 8 is connected to a high-pressure using end 7, and a second one-way valve 6 is arranged between the high-pressure air storage tank 8 and the high-pressure using end 7. The first outlet 41 of the three-way switching valve 4 is connected to the inlet of the high-pressure gas tank 8, and the second outlet 42 of the three-way switching valve 4 is directly connected to the high-pressure use end 7. A branch pipeline 1 is connected between the system air source 11 and the high-pressure air storage tank 8, and a first one-way valve 2 is arranged on the branch pipeline 1. An electromagnetic valve 10 is arranged between a system air source 11 and a control port of the three-way switching valve 4.
A branch pipeline 1 is arranged between the system air source 11 and the high-pressure air storage tank 8 and can directly supply pressure to the high-pressure air storage tank 8, so that the initial pressure of the high-pressure air storage tank 8 when the first booster pump 3 and the second booster pump 9 do not work is the air supply pressure of the system air source 11 instead of atmospheric zero pressure. A first one-way valve 2 is installed on the branch pipeline 1, and when the pressure of the high-pressure air storage tank 8 is higher than the air supply pressure of the system air source 11, the air supply pipeline of the branch pipeline 1 is closed by the first one-way valve 2.
The pipeline from the buffer air storage tank 5 to the high-pressure air storage tank 8 is provided with the three-way switching valve 4, and a first outlet 41 and a second outlet 42 of the three-way switching valve 4 are respectively connected with an air inlet and a high-pressure using end 7 of the high-pressure air storage tank 8, so that the three-way switching valve 4 can be controlled to switch pressurized compressed air to the high-pressure air storage tank 8 or directly to the high-pressure using end 7.
The specific working process is as follows:
when the pressurization work starts, the system air source 11 directly supplies pressure to the high-pressure air storage tank 8 through the branch pipeline 1, and the initial pressure of the high-pressure air storage tank 8 is the air supply pressure of the system air source 11. The first booster pump 3 and the second booster pump 9 work to boost the air pressure of the system air source 11 to the high-pressure compressed air with the set pressure, and the boosted high-pressure compressed air is sent to the high-pressure air storage tank 8 through the first outlet 41 of the three-way switching valve 4. The high-pressure air storage tank 8 receives the pressurized high-pressure compressed air on the basis of the initial stress, the high-pressure air storage tank 8 stores the fully pressurized high-pressure compressed air after a period of time, and the first booster pump 3 and the second booster pump 9 stop working. After the high-pressure using end 7 starts to normally use the high-pressure compressed air, the pressure of the high-pressure air storage tank 8 decreases, the first booster pump 3 and the second booster pump 9 start to work again, and the pressurized high-pressure compressed air is sent to the high-pressure air storage tank 8 through the first outlet 41 of the three-way switching valve 4.
Sometimes, the service flow of the high-pressure service end 7 is an instantaneous super-large flow, the capacity of the high-pressure air storage tank 8 cannot meet the requirement of the instantaneous super-large flow at this time, the electromagnetic valve 10 is energized, the electromagnetic valve 10 is switched, so that the control port of the three-way switching valve 4 is ventilated, the three-way switching valve 4 is controlled to switch the pressurized high-pressure compressed air of the first booster pump 3 and the second booster pump 9 to be directly connected to the high-pressure service end 7, the process of inflating the high-pressure air storage tank 8 is avoided, at this time, the first booster pump 3 and the second booster pump 9 directly supply air to the high-pressure service end 7, and the second one-way valve 6 prevents the high-pressure compressed air of the high-pressure service end 7 higher than the pressure of the high-pressure air storage tank 8 from flowing back to the high-pressure air storage tank 8 at this time. After the instant ultra-large flow demand of the high-pressure using end 7 is finished, the electromagnetic valve 10 is powered off, the electromagnetic valve 10 returns to a normal state, so that the control port of the three-way switching valve 4 exhausts, the three-way switching valve 4 is controlled to switch the high-pressure compressed air after the first booster pump 3 and the second booster pump 9 are boosted again to the high-pressure air storage tank 8, the high-pressure air storage tank 8 is inflated, and the high-pressure compressed air is stored for the next working process.
In the working process, the buffer gas storage tank 5 plays a role in stabilizing the phenomenon of efficiency imbalance between the first booster pump 3 and the second booster pump 9.
