The conveying speed of lubrication prescription and fresh water.
Antifreeze liquid case liquid level sensor 3 is connect with control system 58, if the anti-icing fluid liquid level in antifreeze liquid case 55 is reduced to
When low liquid level LS1, antifreeze liquid case liquid level sensor 3 issues signal to control system 58, and control system 58 is alarmed, and prompts work people
Member fills anti-icing fluid into antifreeze liquid case 55.If anti-icing fluid liquid level is reduced to low liquid level LS2 in antifreeze liquid case 55, level sensing
Device 3 issues signal to control system 58, and control system 58 stops centrifugal pump 12 and closes solenoid valve 15, stops to mixed liquid box 57
Interior conveying antifreezing fluid plays the role of the cavitation erosion of centrifugal pump 12.
Lubricant liquid case liquid level sensor 20 is connect with control system 58, if the anti-icing fluid liquid level in lubricant liquid case 56 drops
When down to low liquid level LS3, lubricant liquid case liquid level sensor 20 issues signal to control system 58, and control system 58 is alarmed, mentioned
Show that staff fills lubricant.If the lubricant level in lubricant liquid case 56 is reduced to low liquid level LS4, liquid level sensor
20 issue signal to control system 58, and control system 58 stops gear pump 28 and closes solenoid valve 32, stops to mixed liquid box 57
Interior conveyor lubricant plays the role of preventing gear pump 28 from cavitating.
If the mixed liquor liquid level in mixed liquid box 57 is increased to high liquid level LS5, mixed liquid box liquid level magnetic column 37 is issued
Signal to control system 58, control system 58 stops the operation of mixed liquor system.If the mixed liquor liquid level in mixed liquid box 57 drops
When down to high liquid level LS6, mixed liquid box liquid level magnetic column 37 issues signal to control system 58, and control system 58 controls mixed liquor
System starts automatically, and carries out mixed liquid according to the proportion set.
Mixed liquid box 57 is connect with remote power feeding system, and remote power feeding system can according to need using the mixing in mixed liquid box 57
Liquid, during mixed liquid, when mixed liquor liquid level is reduced to low liquid level LS7, control system starts to alarm；When mixed liquor liquid level
It is reduced to low liquid level LS8, stops remote power feeding system and uses mixed liquor.
In the present embodiment, low liquid level LS1, low liquid level LS2, low liquid level LS3, low liquid level LS4, high liquid level LS5, high liquid level
LS6, low liquid level LS7, low liquid level LS8 can according to the actual situation by adjusting control system and mixed liquid box liquid level magnetic column into
Row setting.Wherein, control system 58 can eliminate liquid level warning prompting manually.
In mixed liquid system starting of the invention, the centrifugal pump 44 of mixed liquor circulating filtration unit starts to start, mixed liquor
Shut-off valve 41, filter 42, centrifugal pump 44, check-valves 45, filter 46, high mesh number filter 47 are successively passed through by mixed liquid box 57, it is right
Mixed liquor is filtered, while being also functioned to and made the effect of mixed liquor more evenly.When differential pressure pickup 48 detects filter 46, high mesh
When the number big Mr. Yu's setting value of 47 front and back pressure difference of filter, differential pressure pickup 48 issues signal to control system 58, control system alarm,
The prompting and filtering system failure, and stop the operation of centrifugal pump 44.Mixed liquor circulating filtration unit match liquid after the completion of can be delayed after
Reforwarding row five minutes, MANUAL CONTROL mode can also be set according to actual needs.
In conclusion present invention high precision flow, switch time short solenoid valve realize that high-precision matches, and pass through
Liquid level sensor or magnetic column and control system realize the automatic control of the setting of any proportion, system alarm and mixed liquid system
System.The present invention mixes liquid distributing precision height, high degree of automation, high reliablity, and equipment is easy to use, convenient for installation and maintenance,
With good market value.
