Embodiment
With reference to embodiment and accompanying drawing, the utility model is described in further detail, but reality of the present utility model
The mode of applying is not limited only to this.
The utility model aims to provide a kind of flow measuring systems, as shown in Figure 1, it is characterised in that and it includes motor 1,
The motor 1 is connected to air compressor 2, and the air compressor 2 is connected to surge tank 4, the air compressor 2 and buffering
The first connection valve 3 is provided between tank 4, the surge tank 4 is connected to the first air accumulator 6, the air accumulator 6 of surge tank 4 and first
Between be provided with magnetic valve 5, first air accumulator 6 is connected to the second air accumulator 8, the surge tank 4, the first air accumulator 6 and
The lower end of two air accumulators 8 is equipped with blowoff valve 10, and the surge tank 4, the first air accumulator 6 and the upper end of the second air accumulator 8 are equipped with
Safety valve 9, when any one internal pressure is too high in the surge tank 4, the first air accumulator 6 and the second air accumulator 8, safety valve 9
Voluntarily being opened by setting boundary value prevents the too high damage tank body of air pressure, is set between the air accumulator 8 of the first air accumulator 6 and second
There is the second connection valve 7, second air accumulator 8 is connected to noise-decreasing device 13 by the first drain valve 11, and the surge tank 4 is also logical
Cross the second drain valve 12 and be connected to noise-decreasing device 13, noise-decreasing device 13 is used to reduce noise during system overall operation, improves life
Produce the quality of environment；
Wherein, the air compressor 2, surge tank 4, the first air accumulator 6 and the second air accumulator 8 are equipped with pressure sensor
14 and temperature sensor 15, small volume, the degree of accuracy are high, substantially reduce the volume and system complexity of flow system.
When it is implemented, rotational speed determinator can be added on the unit of motor 1 and air compressor 2, motor 1 is obtained in real time
Rotating speed.
Embodiment
When it is implemented, by the first connection valve 3, the second connection valve 7, magnetic valve 5, the first drain valve 11 and the second drain valve
12 is fully open, and the sewage in the first air accumulator 6 and the second air accumulator 8 is all emptied, magnetic valve 5 is then first closed, is closing
The blowoff valve 10 of discharge tank base is closed, normal to start air compressor 2, surge tank 4 starts receiving and comes from air compression
