Description
Technical field
The utility model relates to steam turbine oil tank oil circuit flusher, specifically a kind ofly increases work efficiency, does not affect unit operation, cleans high flux flushing equipment thorough and applied widely.
Background technology
Steam turbine oil supply system is being undertaken the lubricated, cooling of unit and is being controlled the significant tasks such as governing system executing agency.Therefore, the clean quality of this internal system environment, directly affects the safe and reliable operation of unit.Show according to interrelated data, from 1994 to 1996, regulate security personnel and totally 169 of oil system accidents, account for 19.7% of the total accident of power plant, and oil system accident account for wherein 47.1%, that is oil system accident accounts for 9.3% of the total accident of power plant, this is a no small number.
Turbine oil system is installed or during unit high-speed cruising, because of being subject to the impact of many environmental factors, Installed System Memory has more mechanical admixture building, silt dust and because of turbine oil be to cut the grease that forms of body, greasy filth and local floating rust.In order to ensure the safe and reliable operation of unit, reduce oil system and governing system potential faults, the Oil System Flushing after installation and repairing is the last guarantee together before unit puts into operation.
The oil system cleaning of prior art generally has two kinds of methods:
(1), for the oil system connecting with flange, joint, whole oil system pipeline and auxiliary equipment are all pulled down, rinse one by one or pickling with steam;
(2), for the non-removable oil system of Welding Structure, can only utilize the auxiliary oil pump of self to carry out circulation flushing.This purging method time is longer, generally needs to use 15-20 days, affects availability and the economic benefit of unit.
China was all to adopt large flow sectional flushing to the oil system after existing installation in recent years, and the flow that high flux flushing device produces is greater than several times of normal discharges, has oil temperature heater, allows oil temperature fluctuate, and knocks weld bond when flushing.Pipeline, device also have coarse filtration and smart filter screen, the dirts such as the mechanical admixture producing in new unit removing manufacture installation process are had to certain effect, but clear up not thorough, still be there is to potential safety hazard in unit operation, and clear up in order to upper method, the grease that in long-time production run, absorption is deposited on system inwall is difficult to clean out.
In overall reasonability, also there are some shortcomings and deficiencies in the large flow apparatus for current existing use; as excessive in separate unit oil pump flow; in running, system and equipment of itself thereof are not protected; thereby there will be in use because the pump housing, motor break down, because maintenance affects the normal duration.Automatic backwash appears better than it is, extremely impracticable.And for example system is connected not only consumptive material but also takes a lot of work with the installation of device, incurs loss through delay the duration, loses more than gain.
In sum, the problem that the cleaning method of prior art on turbine oil system and equipment exist is: inefficiency, the availability that affect unit and cleaning are not thorough.
