Description
One, technical field
The utility model relates to the purification plant of lubricant oil, particularly the purification plant of on-line operation.
Two, background technique
Large scale industries such as Turbo-generator Set, hydraulic generator unit equipment all has the special-purpose oil supply system of oneself, in order to lubricated each rotatable parts and adjusting kinetic energy etc.The oily medium that uses in its system is generally industrial lubricant, as: L-TSA46 lubricant oil, 32L-TSA lubricates wet goods.Normally operational relation is close for the quality of quality of lubrication oil and unit: the degenerate performance and the oil-film force that make lubricant oil of oil changes, and causes each lubricating component finely not lubricate, and the result damages the fusing of bearing shell coal; Also can make the regulating system parts be corroded, get rusty and bite, cause regulating system and protective gear action serious consequence such as malfunctioning.So must guarantee the quality of used lubricant oil in the unit oil supply system.
The lubrication oil supply system of existing Turbo-generator Set (hydraulic generator unit) mainly comprises main oil pump, main fuel tank, purification plant, oil tank, auxiliary oil transfer pump, oil cooler, oil purifier, high and low pressure excess pressure valve etc., is connected by connecting tube therebetween.During unit work, its lubrication system, regulating system need the lubrication oil circulation of a large amount of cleanings to supply with, and are about about 5000L/h as the purification plant of a 200MW unit and the fuel delivery of oil tank.These lubricant oil are transported to each lubricant housings of unit by other the auxiliary oil transfer pump on main oil pump and the main fuel tank, and circulation is flowed back in the main fuel tank again.In normal operation, all lubricant oil in the main fuel tank pass through auxiliary oil transfer pump and connect oil pipe to each working position for per hour average 5～12 times, return main fuel tank then.But because working position temperature, pressure effect and pipeline leakage and other influences, turbine oil can be contaminated, and oil quality reduces.Wherein purification plant and oil tank are special in quality and the quantity that guarantees oil product in the main fuel tank is provided with, and are the requisite devices of unit safety operation.
The special-purpose oil filter of the lubricant oil of existing steam turbine, water turbine industry wide selection, mainly form, connect by pipeline therebetween by coarse-grain filtering device, heater, gravity rotational flow separation chamber, chemisorption chamber, vacuum separation chamber, buffer, vacuum pump, safety cage, oil transfer pump, accurate filter, sensor, solenoid valve and electrical control cabinet etc.And between electrical control cabinet and sensor and the solenoid valve, connect by lead.The special-purpose oil filter of this lubricant oil removes thick mechanical admixture in the lubricant oil to be clean by coarse-grain filtering device earlier, after back heater via makes lubricant oil intensification viscosity reduction, again by the earlier thick dehydration in gravity rotational flow separation chamber, remove the large quantity of moisture in the oil after, aging component in the adsorbing and removing oil of chemisorption chamber again; And then deeply remove micro free water in the oil, dissolving water by the vacuum separation chamber, remove the combined purifying scheme of minute impurities etc. at last by accurate filter, moisture content in lubricating can be reduced to below the 100ppm, even (as: unit leaks few) can satisfy the requirement that a lot of big units require water ratio of lubricating oil≤50ppm under specific circumstances.So the special-purpose oil filter of the lubricant oil of band vacuum dewatering system obtains promotion and application widely.But the special-purpose oil filter of this lubricant oil is a kind of independent operating, movable machine equipment, can not be as vapour, hydraulic generator unit, and a kind of supplementary equipment on-line operation in the oil supply system, coordinated operation; Secondly, the oil transfer pump in the vacuum dewatering system, vacuum pump, sealing system are easy to generate fault, and its trouble signal can not be transferred to vapour, hydraulic generator unit Operational Control Room in time, exactly on the one hand when breaking down; On the other hand; this vacuum dewatering system lacks the overhaul reserve scheme; in case break down; must shut down maintenance; and short then a few hours of repair time; long then a couple of days,, have a strong impact on Oil gallery in service system oil if will influence the security of operation of main frame in service during the lubricant oil of no overhaul reserve special use oil filter on-line operation.
