The concrete steps of using aforementioned system to clean are divided into three phases, and the phase I is outside lube pipe to be thrown the oil string wash, and mainly is to remove attached to impurity such as the iron rust in the exterior line, scums; Second stage is that the main frame internal duct is thrown the oil string and washed, and exterior line and main frame pipeline is connected, but the lubricating point of each moving element of main frame is given shutoff, goes here and there when washing in each moving elements such as impurity being brought into bearing to prevent to throw oil; The 3rd team's section is each motive position lubricating point flushing of main frame, remains in the impurity in the moving element gap with removal.
Specific operation are following:
As shown in Figure 1; Throw in the oily process in the phase I; Earlier exterior line and diesel main engine 1 internal duct are broken off; Again first, second and third jumper pipe 7,8,9 is connected respectively, with oil cooler 3, three-way valve 4 and lubricating oil from secondary cleaner 5 bypass (otherwise impurity will get into main frame oil cooler 3, three-way valve and 4 lubricating oil from secondary cleaner 5, pollutes).Whether check system is complete, and simultaneously, suitable position is installed air pump and connected source of the gas on pipeline.
After all equipments are appropriate, can be to the lubricating oil of lubricating oil circulating tank 2 filling cleanings, during oil feed, we install a filter screen at filler, to prevent secondary pollution; After reaching certain oil level, can open oil pump 21 and carry out the clear work of exterior line throwing oil, throw in the oily process; The staff need often knock pipeline (general 2 hours once), and the impurity in the pipeline can be peeled off fully, checks inspection filter 10 filter paper simultaneously; Till not having macroscopic impurity in the filter paper; At this moment, we finish to think that the phase I throws oil work, change second stage over to and throw oil work.
As shown in Figure 2; Throw in the oily process in second stage, each jumper pipe is unloaded, simultaneously exterior line and diesel main engine 1 internal duct are connected; But the lubricating point to diesel main engine 1 each moving element is given shutoff; When washing impurity is brought in each moving element such as bearing to prevent to throw the oil string, accomplish install after, member outer surface such as clean internal frame, oil sump, connecting rod, bent axle protection oil.Continue logical lubricating oil the diesel main engine internal duct is cleaned, to house steward terminal inspection of inspection bag and cleaning, naked eyes can't be found impurity in the final inspection bag, think and throw the oil cleaning through repeatedly; By the throwing oil flushing work that can carry out the phase III after the final affirmation of host services merchant.
Through the work of the throwing in preceding two stages oil, the impurity in outside lube pipe and the main frame internal duct has been gone here and there wash clean basically, does not remove but locate also to have some residual impurity at bearing etc., therefore, need wash lubricant housings such as these bearings.
Before the flushing, will give the parts dismounting of shutoff, and make inner each hydraulic fluid port of main frame facing to each moving element to the lubricating point of diesel main engine 1 each moving element; Open main lubricating oil pump then, lubricating oil pump to main frame is inner, make lubricating oil pass through pipeline and arrive each moving element place; (flushing pressure is 0.3～0.4MPa) usually under certain pressure; The impurity that lubricant oil will remain on the moving element is taken away, and washes after 4～6 hours whole throwing oil flushing end-of-job.
Through the throwing oil process of above three phases, and control program, we think that main frame lube pipe inside has been in clean state; But for making the shipowner relieved; We draw the part oil sample and carry out the oil content detection behind the throwing oil end-of-job of phase III from lubricant oil, the detecting method of taking usually is to use oil content detector (See Figure); Usually, every milliliter of oil sample grain count reach≤19/15 (greater than 5 micron particles numbers should be less than 5000, should be greater than 15 micron particles numbers less than 320) for qualified.
Through the throwing oil work in above each stage, the inner impurity of main frame oil system is removed basically, and this prolongs the maintenance and the service cycle of main frame to reducing each moving element wearing and tearing such as main frame bearing, bearing shell, and reducing the main frame maintenance expenses all has practical significance.
