Detailed description of the invention
Below in conjunction with Figure of description, this utility model is further elaborated。
Such as Fig. 1, shown in 2, the air pump equipment of a kind of analytical tool of this utility model, there is air compressor machine 2 (oilless air compressor), gas pressure regulator 8 and air accumulator, wherein, air compressor machine 2 is two, gas pressure regulator 8 is two, by each self-configuring of air compressor machine 2, the air inlet place of two air compressor machines 2 is provided with a set of air filter jointly, the gas outlet of two air compressor machines 2 is connected with a condensing tube 4, the outlet of condensing tube 4 is connected to drain valve assembly 7, the air vent of drain valve assembly 7 is connected to air accumulator 5 through check valve 6, the pressure-detecting device of pressure controller 8 it is provided with in air accumulator 5, the control signal of pressure controller 8 delivers to the control loop of air compressor machine 2。
This utility model also includes two-stage pressure maintaining valve, the air pipe of air accumulator 5 gas outlet is connected to the source of the gas delivery outlet for big flow instrument through first order pressure maintaining valve, the air pipe of air accumulator 5 gas outlet is divided into two-way after first order pressure maintaining valve is then through second level pressure maintaining valve, one tunnel is the source of the gas delivery outlet used for low discharge instrument, and another road is front panel 11 Pressure gauge display pressure。
This utility model also has emptying solenoid valve 9, it is installed on the pipeline between condensing tube 4 to check valve 6, when in air accumulator 5, pressure reaches the upper pressure limit that gas pressure regulator 8 sets, gas pressure regulator 8 exports control signal, emptying solenoid valve 9 action to emptying solenoid valve 9。
During the low pressure limit that in air accumulator 5, pressure sets lower than gas pressure regulator 8, gas pressure regulator 8 exports control signal to air compressor machine 2, and air compressor machine 2 starts。
As it is shown in figure 1, work process of the present utility model is as follows: turn on the power switch 12, two air compressor machines 2 start simultaneously at work, are sucked from air inlet by air and start compression after filtering, discharge condensed pipe 4 from the gas outlet of air compressor machine 2 and water trap 7 filters moisture；Air after filtration enters in air accumulator 5 through check valve 6, and gas pressure regulator 8 detects pressure inside the tank；When in air accumulator 5, pressure reaches the upper pressure limit that gas pressure regulator 8 sets, air compressor machine 2 quits work, emptying solenoid valve 9 action simultaneously, is bled off by the gas in condensing tube 4 to check valve 6 pipeline。A startup when 5 pressure are lower than low pressure limit in air accumulator, in air compressor machine 2。
