Abstract
The present invention provided a purifying system for regulating and lubricating oil of steam turbogenerator set under 200 MW. The output pipe (high pressure pipe line) of the high pressure starting pump is divided into two branches, one branch is regulating oil circuit, the other is the lubricating oil circuit. Said invention features that on two ends of main valve of high pressure pipe line, the high pressure integrated oil purifier is connected parallelly. It can filtrate both on-line and off-line and filtrate the regulating oil and lubricating oil simultaneously, it can heighten efficiency, lower cost and easy operate.
Description
The present invention relates to the cleaning system of adjusting of 200MW and following Turbo-generator Set thereof and lubrication oil.
The turbidity test of electric power system 200MW and following steam turbine generator adjusting oil and lubricant oil play crucial effects to the normal operation of unit.Wherein regulating oil is high pressure oil, and lubricant oil is low pressure oil.At present following two kinds of methods are mainly adopted in the filtration of fluid: the one, filtrating equipment is installed in the bypass of lubricating oil pipeline (referring to Fig. 1), only lubricant oil is filtered (because the rated pressure of this filtrating equipment itself is 0.8Mpa), can not filter with oil the regulating system of high-pressure high-flow simultaneously.The 2nd, after overhaul, the fluid that utilizes external backwash dress to rotate filters.This method can not realize on-line filtration, and trouble is installed, and cost height, filtering effect are also bad.Because this Rinsing unit outlet pressure is lower.
The purpose of this invention is to provide a kind of 200MW and following Turbo-generator Set oil cleaning system thereof.
The object of the present invention is achieved like this; 200MW and following Turbo-generator Set oil cleaning system thereof are: high voltage startup scavenge delivery---pressure duct, be divided into two, one the tunnel is lubricating oil path, one the tunnel for regulating oil circuit, feature of the present invention is: the two ends of the main valve on the high pressure oil pipeline, and the purification plant of the integrated oil of connection high pressure, the purification plant of the integrated oil of this high pressure is made up of mud chamber, inlet space and filter chamber etc. from bottom to top, and filter chamber's lining is filter screen and permanent magnet.During filtration, main valve is closed, high pressure oil enters the inlet space of the purification plant of the integrated oil of high pressure, and the impurity that particle is bigger in the oil is fallen into the mud chamber under action of gravity, and high pressure oil enters the filter chamber again, the magnetic conductivity impurity absorption is to magnet in the oil, the non-magnetic impurity absorption is to filter screen, and the oil after the filtration flows out from the filter chamber, enters high-pressure oil pipe again, one the tunnel advances lubricating oil path, and another road enters the adjusting oil circuit.The Chinese patent CN95232649.3 document that sees the applicant's application for details about the structure and the working principle thereof of the purification plant of the integrated oil of high pressure.
The present invention compared with prior art has following characteristics:
1, the integrated reconditioner of this high pressure belongs to the high-pressure high-flow purification plant, P 〉=1.5Mpa, Q 〉=4000l/min, can be parallel in the high pressure oil pipeline behind the high voltage startup oil pump, thereby realize that lubricant oil filters with oil simultaneously with regulating, reach the purpose of dual-use, improved manufacturing efficiency, and reduced cost.
2, the application of new system; (during unit operation) filtered in the time of both can be online, can filter (in the past in the unit running process, under the situation that regulating system exceeds standard with the oil pollution grade by off-line (during compressor emergency shutdown) again; have only to shut down and carry out the off-line filtration), reduced economic loss.
3, install simply, easy to operate, volume is little.
4, the integrated reconditioner of high pressure, this device have adopted slightly, smart, magnetic hybrid filtering and the mode that the mud chamber with special construction combines owing to having adopted, and have improved filtering effect, have reduced cleaning time.
Further specify the present invention below in conjunction with accompanying drawing.
Fig. 1 is existing Turbo-generator Set oil purification system block diagram.
Fig. 2 is the present invention---the following Turbo-generator Set cleaning system of 200MW block diagram.
Fig. 3 is two purification plants block diagrams in parallel.
Fig. 4 is the skeleton diagram that four filtrating equipments connect.
High voltage startup oil pump 1 output tube---pressure duct, be divided into two, one the tunnel is lubricating oil path, one the tunnel for regulating oil circuit, feature of the present invention is: the two ends of the main valve 2 on the high pressure oil pipeline, and the purification plant 3 of the integrated oil of connection high pressure, the purification plant of the integrated oil of this high pressure is made up of mud chamber, inlet space and filter chamber etc. from bottom to top, and filter chamber's lining is filter screen and permanent magnet.During filtration, main valve is closed, high pressure oil enters the inlet space of the purification plant of the integrated oil of high pressure, and the impurity that particle is bigger in the oil is fallen into the mud chamber under action of gravity, and high pressure oil enters the filter chamber again, the magnetic conductivity impurity absorption is to magnet in the oil, the non-magnetic impurity absorption is to filter screen, and the oil after the filtration flows out from the filter chamber, enters high-pressure oil pipe again, one the tunnel advances lubricating oil path, and another road enters the adjusting oil circuit.The Chinese patent CN95232649.3 document that sees the applicant's application for details about the structure and the working principle thereof of the purification plant of the integrated oil of high pressure.
In order to improve purification efficiency, can be with two purification plants, 3 in parallel uses, the oil inlet pipe that is about to two purification plants 3 connects together, and oil outlet tube connects together.Fig. 3 is exactly this usage mode.
In order to improve purification efficiency, and improve and purify grade, use can also combine four purification plants, referring to Fig. 4, being about to two identical purification plants of filtration grade is together in parallel as one group, and then two groups be together in series, one group that filtration grade is low as the first order, another group that filtration grade is high is as the second level, filtration grade is directly proportional with the magnetic intensity of magnet and the precision of filter screen, oil at first carries out coarse filtration through first group of filtrating equipment, carefully filters through second group of filtrating equipment then.
