The operation principle and the process of native system are as follows
As shown in Figure 2, ROLLING OIL filter process:
Dirty oil after rolling flows into oil sump tank 27 by the 5th petroleum pipeline 26, pump into dirty fuel tank 3 with scavenge oil pump 29 by oil return pipe 28, many dirty oil pumps 17 enter dirty oil respectively in the main filtering tank 1 through dirty oil pipe 16 from dirty fuel tank 3, main filtering tank 1 can be arranged side by side a plurality of, generally at least 3, after filter 11 in main filtering tank 1 in it filters, by filter pump 9 absolute oil after filtering is pumped to absolute oil case 2 through absolute oil pipe 7 again, absolute oil arrives the milling train nozzle by spray pump 45, heat exchanger 40, fuel feed pump 24 again, is sprayed onto on the lubricating system and stainless sheet steel of milling train.
As shown in Figure 3, the backwash process of main filtering tank internal filter:
After the surfaces externally and internally pressure differential of the filter 11 work regular hour after-filters 11 in the main filtering tank 1 surpasses setting, need carry out backwash to filter 11 outer surfaces with compressed air, its objective is the impurity that is attached on the filter outer surface is swept away, guarantee the normal filtration ability of filter 11.When carrying out backwash, at first oil scavenge pump 23 is drawn onto the oil of main filtering tank 1 in the dirty fuel tank 3 by fuel sucking pipe 21, air accumulator 4 compressed airs enter in the main filtering tank 1 by compressed air hose 19, absolute oil pipe 7 then, filter 11 inner surfaces are carried out repeatedly blowback, when blowback, scavenging pump 15 work, absolute oil washes by the outer surface of 14 pairs of filters 11 of scavenge pipe in the absolute oil case 2.The sump oil that washes is extracted into the fractional precipitation fuel tank by residue oil pipe 35, dredge pump 37 with it.A plurality of main filtering tank 1 backwashes not at the same time between recoil in the section, should take turns recoil respectively, automatically control by programming by electric control system and carry out.
As shown in Figure 4, main filtering tank self-loopa process:
After backwash is finished, leave certain impurity in absolute oil pipe 7 pipelines and in the oil duct of filter 11, the function of self-loopa is that these impurity are washed, and does not allow it directly get back in the absolute oil case 2 and goes.Its working cycles system is: after backwash finishes, dirty oil pump 17 with dirty oil from dirty fuel tank 3 by in the dirty oil pipe 16 suction master filtering tanks 1, when liquid level exceeded filtration in the maximum layer filter 11 and pulls in main filtering tank 1, dirty oil pump 17 cut out.Filter pump 9 startings, second valve 10 and the 5th valve 20 are closed, and first valve 8 and the 3rd valve 13 are opened, and the oil in the main filtering tank 1 circulates by filter 11, first valve 8, absolute oil pipe 7 and the 3rd valve 13.
As shown in Figure 5, sump oil processing procedure:
From the sump oil that main filtering tank 1 backwash is got off, need just can re-use after treatment.Sump oil treatment system major function is that sump oil is divided into clean ROLLING OIL and mud, and clean ROLLING OIL is returned dirty fuel tank 3, and mud discharging goes out outside the system.Its working cycles system is: sump oil pumps into a settling tank in the fractional precipitation fuel tank 6 internal classification filters 61 by residue oil pipe 35 by dredge pump 37 in the main filtering tank 1, and the oil spill that precipitated is gone into No. two fuel tanks and precipitated and overflow into fuel tank again No. three.Oil in No. three fuel tanks is extracted in the secondary filter jar 5 by secondary filter pump 39, filters through the filters in the secondary filter jar 5 51, turns back to dirty fuel tank 3 by secondary filter jar 5 internal filters 51, realizes that sump oil re-uses.
As shown in Figure 6, secondary filter jar backwash process:
The backwash of secondary filter jar is closed the 7th valve 30, the 9th valve 34 after finishing, and opens the 8th valve 32 that leads to dirty fuel tank 3, carries out new secondary filter again.
As shown in Figure 7, fuel feeding process:
During the paramount liquid level of absolute oil case 2, can open spray pump 45, oil is sprayed onto on the milling train by fuel feed pump 24 according to the milling train oil require.The warm adjusting of oil can be cooled off by the heating of the heater in the absolute oil case 2 or by heat exchanger 40, is controlled automatically by temperature control valve, guarantees to be sprayed onto the suitable oil temperature of milling train nozzle.
The electrical control process:
Electric control system adopts Programmable Logic Controller to carry out centralized Control, signals such as temperature, pressure, liquid level and flow in the Programmable Logic Controller acquisition filter system, according to the technological parameter that is provided with, in conjunction with control program able to programme, the output control signal is carried out the signal conversion to electrical control cabinet, controls the switch of executive components such as oil pump, valve class by electrical control cabinet.The anti-again malen of the switching signal of executive component carries out dynamic process to Programmable Logic Controller.
This filtration system for rolled lubricating oil has telotism and the filtering accuracy characteristic is good; Therefore, it is applicable to the secondary filter of the lubricating oil of the corrosion resistant plate milling train, copper coin milling train or the accurate plate mill that require rolling accuracy very high.
