The low sender point of point, reference bit sender point, liquid level, the extremely low sender point of liquid level.
In addition, in order to limit the maximum pressure in pressure oil storage tank, it is ensured that the safety for using, in the gas of pressure oil storage tank
Side roof part outside is provided with safety valve 10, safety valve model A41Y-16C, DN25, PN16bar, and preset security pressure value is
8bar。
Fuel outlet valve 15 is additionally provided with the bottom of pressure oil storage tank, fuel outlet valve is hand-operated valve, can be by pressure when maintenance
Oil emptying in oil storage tank.
After oil lubricating system pump startup, lubricating pump starts outward for lubricating oil, and fuel inlet ball check valve is opened, and lubricating oil enters pressure
In power oil storage tank 11, the gas path on-off valve 4 and gas circuit vent valve at this moment calmed the anger on pipeline are closed, at oil circuit on-off valve
In open mode, the meeting low pressure sender of pressure switch 8, when liquid level is gradually increasing, the gas in pressure oil storage tank is compressed, pressure
Rise, when pressure rises to 8 low pressure not sender of pressure switch, liquid level rises can become very slow, if liquid level gauge 12 is not extremely
Reference bit sender, illustrates that the liquid level of pressure oil storage tank not yet reaches requirement, and at this moment gas circuit vent valve 9 is opened, pressure oil storage tank
Gas side pressure starts to reduce, and liquid level continues to raise, when liquid level is increased to 12 reference bit sender of liquid level gauge, gas circuit vent valve 9
Close, liquid level may proceed to rise, while gas pressure starts to increase in pressure oil storage tank, pressure switch 8 can be with tank internal pressure
Power gradually increases, its will not low pressure sender, when liquid level rises to a certain extent, pressure inside the tank starts balance, and liquid level will not
Continue to rise, system pressure stabilization starts normal work.
If liquid level continues to rise, when rising to the liquid level of liquid level gauge 12 sender high, gas path on-off valve 3 will be opened, and gas circuit is put
Air valve 9 is closed, pressurized cylinder start working, air pressure begins to ramp up in pressure oil storage tank, set pressurized cylinder by air pressure in tank increase to
More than pressure fuel pump, the meeting high pressure sender of pressure switch 8, liquid level begins to decline in pressure oil storage tank after a period of time, works as liquid level
Drop to liquid level gauge reference bit not sender when, gas path on-off valve 3 is closed, and stopping is supplied gas supercharging, and liquid level stops declining, and maintains to put down
Weighing apparatus, air pressure can drop to normal range (NR) in tank, the high pressure of pressure switch 8 not sender, system worked well.
If after system worked well, liquid level also slowly rises in tank, and is aided with the low pressure of pressure switch 8 and starts sender,
May be considered what the original paper bad seals gas leakage in gas circuit was caused, remind staff to be checked；If liquid level after
Continuous to rise at the high level of liquid level gauge 12, then gas path on-off valve 4 is opened, and pressurized cylinder is started working, and gas pressure starts to increase,
Liquid level is down to the reference bit of liquid level gauge 12 not after sender, and gas path on-off valve is closed, and stops being pressurized in pressure oil storage tank；If gas circuit
On-off valve 4 is opened, the situation that pressurized cylinder is started working, and liquid level also continues to rise, and rises to the high sender of liquid level of liquid level gauge 12, then
Illustrate that gas path on-off valve or pressurized cylinder are damaged, point out pressure oil storage tank gas path failure, overhaul at once, while offering controlled on main rolling line
Room processed, it is desirable to which the oil lubricating system is shut down, main rolling line stopped steel；If after system worked well, liquid level continuous decrease,
And be aided with the high pressure sender of pressure switch 8, then may determine that it is gas path on-off valve failure, valve can not be closed, and should point out work
Personnel placement is overhauled, and when liquid level drops to the low sender of the liquid level of liquid level gauge 12, then answers opening gas circuit vent valve 9, and liquid level is improved
To the reference bit sender of liquid level gauge 12, gas circuit vent valve 9 is closed, if liquid level is repeatedly in the reference bit of liquid level gauge 12 and liquid level low level
Between if migration, airline pressure should be pointed out too high, remind staff to adjust again gas pressure, if opening vent valve 9
Afterwards, liquid level continues to reduce, and is reduced to the extremely low sender of liquid level of liquid level gauge 12, then illustrate that catastrophe failure occurs in system, should offer
Control room on main rolling line, it is desirable to which the oil lubricating system is shut down, main rolling line stopped steel, and shutdown inspection reason.
When oil lubricating system orderly closedown (lubricating pump fuel cut-off), then should opening gas circuit on-off valve 4, closing gas
Road vent valve 9, opens oil circuit on-off valve 13, and pressurized cylinder is started working and uses tank inner fluid discharge supply arrangement, when liquid level drop
During sender low to the liquid level of liquid level gauge 12, gas path on-off valve 4 is closed, when liquid level drops to the extremely low sender of the liquid level of liquid level gauge 12, oil
Road on-off valve is closed.
When oil lubricating system is because of accidental shutdown, when the control of pressure oil storage tank is with orderly closedown as, but need notify
Main roll line control room, oil lubricating system is accidental shutdown, and notifies that staff is checked it.
High-speed rod thin oil lubricant pressure oil storage tank control device of the invention, simple structure, it is easy to maintenance, with tube capacity
Easily, the automaticity of pressure oil storage tank can be greatly improved, by Liquid level in tank in the reasonable scope, and stabilization pressure
Power, can really play a part of the equipment safety protection to needing lubrication.
Below high-speed rod thin oil lubricant pressure oil storage tank control device of the invention is only elaborated by way of example,
This few example is only used for explanation principle of the invention and embodiments thereof, rather than limitation of the present invention, is not departing from this hair
