Abstract
The invention belongs to screw machine compressor set used in Gas Industry into sledge field, specifically device in Gas power industry, a kind of used mode of unit seamless switching.It is characterized in that：Increase the storage tank of big volume on Screw chiller, and increase the pressure at expulsion of screw machine, increase the pressure in storage tank, the gas in storage tank is persistently supplied within the time that unit switches to device in Gas generator, reach unit and switch non-stop-machine purpose.The present invention takes full advantage of the compressibility of gas; gas is stored using storage tank; the generating set of rear end is switched compressor set under not stopped status, the stability and reliability of gas electricity unit can be greatly improved, be allowed to the continual normal power generation power supply of generating set.
Description
Technical field
The invention belongs to screw machine compressor set used in Gas Industry into sledge field, specifically device in Gas, which generates electricity, goes
Industry, a kind of used mode of unit seamless switching.
Background technology
There is guest machine at traditional gas station scene, when the unit of normal operation is shut down suddenly, it is necessary to which the regular hour enables
Standby unit, within this period that guest machine is opened, situation about dying occurs in rear end, and so the production in well site can be made
Into certain influence.
The content of the invention
The present invention be exactly in order to solve above-mentioned technical problem, and a kind of a kind of unit safe and reliable to operation invented without
The mode that seaming and cutting are changed.
In order to reach the effect above, the invention adopts the following technical scheme that：
A kind of mode of unit seamless switching, it is characterized in that：Increase the storage tank of big volume on Screw chiller, and increase spiral shell
The pressure at expulsion of bar machine, increase storage tank in pressure, allow the gas in storage tank within the time that unit switch persistently to watt
This gas generator supplies, and reaches unit and switches non-stop-machine purpose.
A kind of mode of unit seamless switching of the present invention, it is characterized in that：Device in Gas generator requirement gas pressure be
0.5MPaG, the pressure in storage tank is 0.8MPaG, increases pressure regulator valve before storage tank and gas electricity machine, the pressure before pressure regulator valve
Power is 0.5-0.8MPaG, and pressure maintains 0.5MPaG always after pressure regulation.
A kind of mode of unit seamless switching is invented, when a unit cancel closedown, the pressure in storage tank is by 0.8MPaG
Time required for being reduced to 0.5MPaG is 5 minutes, can start another compressor group completely within this time, reach
Switch the purpose of Screw chiller under to the non-stop-machine state of generator.
This technical scheme can carry out different configurations according to the air consumption at scene to storage tank and pressure
Compared with prior art, beneficial effects of the present invention are as follows：The present invention takes full advantage of the compressibility of gas,
Gas is stored using storage tank, the generating set of rear end is switched compressor set under not stopped status, gas can be greatly improved
The stability of generating set, reduce the influence that unit failure is brought to production.
Brief description of the drawings
Fig. 1 is the fundamental diagram of the present invention.
Marked in figure：V-101 and V-201 is pressure vessel
Embodiment
Pressure after screw machine compression of the present invention is 0.8MPaG, and gas is introduced into storage tank after compression, then through toning
The pressure regulation of pressure valve, enter the use of gas electricity unit.
When unit A cancel closedowns, the running status of B of Unit automatic detection main motor, when A main frames do not work, immediately
Start B units, reached full load condition within 5 minutes, reach normal operating condition, can prevent the gas of screw machine rear end from sending out
Group of motors is shut down, and the stability and reliability of production is effectively ensured.
In summary, the present invention takes full advantage of the compressibility of gas, stores gas using storage tank, makes the generating of rear end
Unit switches compressor set under not stopped status, can greatly improve the stability and reliability of gas electricity unit, be allowed to
The continual normal power generation power supply of generating set.
