Abstract

The utility model discloses a kind of gas meter calibrating installation energy-saving dynamic system, it comprises many group giant groups and one group of small nozzle group, what often group giant group was connected in parallel by the giant of multiple different size is formed, small nozzle group is connected in parallel by the small nozzle of multiple different size and forms, giant group connects atmospheric surge tank by header, and atmospheric surge tank connects high-power water ring vacuum pump; Small nozzle group connects little gas surge tank, and little gas surge tank connects miniwatt water ring vacuum pump, and high-power water ring vacuum pump is connected in gas passage by pipeline with miniwatt water ring vacuum pump.After adopting above-mentioned structure, divide into groups by the parallel connection of small nozzle group and small nozzle group and often organize the setting of different size nozzle in giant group and small nozzle group, by various flow rate various combination, the nozzle of different bore can be made to reach critical conditions fast, saved the energy.

Description

Gas meter calibrating installation energy-saving dynamic system
Technical field
The utility model relates to a kind of power system of gas meter calibrating installation, and specifically a kind of gas meter calibrating installation energy-saving dynamic system, belongs to flow metering technical field.
Background technology
The surge tank of gas meter calibrating installation power system and pump component become two parts, traditionally, and hand line nozzle (1m 3/ h ~ 128m 3/ h) use minibuffer tank and pump machine, heavy caliber nozzle (256m 3/ h ~ 1250m 3/ h) use large surge tank and pump machine.When using hand line nozzle, under pump machine continuous firing, when hand line nozzle back pressure is than≤0.75, nozzle reaches critical conditions and remains unchanged, and so reaches the setting flow velocity of nozzle.When using heavy caliber nozzle, under pump machine continuous firing, back pressure can reach critical conditions than≤0.85, now reaches the setting flow velocity of nozzle.If the surge tank that hand line nozzle uses with heavy caliber nozzle is communicated with, when using hand line nozzle, pump machine needs to work long hours to reach≤and 0.75 make hand line nozzle reach critical conditions, cause energy dissipation.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of gas meter calibrating installation energy-saving dynamic system providing height back pressure ratio simultaneously, reduce energy consumption.
In order to solve the problems of the technologies described above, gas meter calibrating installation energy-saving dynamic system of the present utility model, comprise many group giant groups and one group of small nozzle group, what often group giant group was connected in parallel by the giant of multiple different size is formed, small nozzle group is connected in parallel by the small nozzle of multiple different size and forms, giant group connects atmospheric surge tank by header, and atmospheric surge tank connects high-power water ring vacuum pump; Small nozzle group connects little gas surge tank, and little gas surge tank connects miniwatt water ring vacuum pump, and high-power water ring vacuum pump is connected in gas passage by pipeline with miniwatt water ring vacuum pump.
What described often group giant group was connected in parallel by the giant of three different sizes is formed, and small nozzle group is connected in parallel by the small nozzle of five different sizes and forms.
After adopting above-mentioned structure, due to many groups giant group and one group of small nozzle group of setting, what often group giant group was connected in parallel by the giant of multiple different size is formed, small nozzle group is connected in parallel by the small nozzle of multiple different size and forms, divide into groups by the parallel connection of small nozzle group and small nozzle group and often organize the setting of different size nozzle in giant group and small nozzle group, by various flow rate various combination, the nozzle of different bore can be made to reach critical conditions fast, saved the energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model gas meter calibrating installation energy-saving dynamic system.
Embodiment
Below in conjunction with the drawings and specific embodiments, gas meter calibrating installation energy-saving dynamic system of the present utility model is described in further detail.
As shown in Figure 1, gas meter calibrating installation energy-saving dynamic system of the present utility model, comprise many group giant groups 1 and one group of small nozzle group 2, what often group giant group 1 was connected in parallel by the giant of multiple different size is formed, air-flow can enter in giant group from the giant group air intake opening 9 often organizing giant group 1, small nozzle group 2 is connected in parallel by the small nozzle of multiple different size and forms, air-flow can enter in small nozzle group from the small nozzle group air intake opening 10 of small nozzle group 2, giant group 1 connects atmospheric surge tank 4 by header 3, atmospheric surge tank 4 connects high-power water ring vacuum pump 5, small nozzle group 2 connects little gas surge tank 6, and little gas surge tank 6 connects miniwatt water ring vacuum pump 7, and high-power water ring vacuum pump 5 is connected in gas passage 8 by pipeline with miniwatt water ring vacuum pump 7.
Preferably, what often group giant group 1 was connected in parallel by the giant of three different sizes is formed, and small nozzle group 2 is connected in parallel by the small nozzle of five different sizes and forms.
