Disclosure of Invention
The invention aims to provide a method for blocking oil leakage on a joint surface of an oil cylinder, which can solve the problem of oil leakage on the upper and lower joint surfaces of the oil cylinder in a short time without large equipment transformation.
In order to solve the technical problems, the invention adopts the following technical scheme:
the invention relates to a method for blocking oil leakage on a joint surface of an oil cylinder, which comprises the following steps:
1) filling a gap between the cylinder surface end difference by lead wires with phi being 0.7mm according to the measurement data with the cylinder surface end difference being 0.3 mm;
2) in order to prevent the lead wire from shifting, high-temperature-resistant sealant is coated on the surface of the cylinder to fix the lead wire, so that the lead wire is prevented from being filled in a wrong position;
3) temporarily hoisting the upper cylinder body, and temporarily fixing according to the returned specification and size, wherein the purpose is to extrude the lead wire and simultaneously measure whether the lead wire can completely fill the gap;
4) and hoisting the upper cylinder body, taking down the lead wire to measure the size of the end difference position of the filling gap, if the size is larger than 0.3mm, proving that the end difference gap can be completely filled, and if the size is smaller than 0.3mm, selecting a lead wire with the size of one size larger than the lead wire, and continuously repeating the process to fill the end difference gap until the size of the end difference position of the filling gap is measured and is larger than 0.3 mm.
Further, the cylinder body reinstalled in the step 3) is fixed by bolts.
Compared with the prior art, the invention has the beneficial technical effects that:
according to the method for improving and blocking the oil leakage, the soft material filler is used for blocking the place with the uneven joint surface and the end difference, the material cost is simple, the equipment improvement place is few, a new sealing device is not needed, or the equipment is turned, drilled and the like, but the accurate measurement is needed, and the end difference point of the joint surface is accurately found out so as to be convenient for accurate sealing.
The invention is applied to the joint surface sections of the upper cylinder and the lower cylinder of the bearing bush oil chamber of the air compressor of the gas turbine unit, and the maintenance period of the air compressor is shortened through the improvement, the original scheme is to dismantle and adjust the joint surface end difference of the upper cylinder and the lower cylinder of the bearing bush oil chamber again, the construction period is probably 10 days, and through the improvement, the construction period is shortened to 1 day. And in the debugging stage after the unit is overhauled in 1 month, the oil leakage at the position is not found by checking during oil flushing and turning, the oil leakage point is rechecked again when the unit is eliminated in 3 months, and the oil leakage phenomenon is not found, so that the problem of oil leakage at the position is solved.
