Description
Technical field
The invention belongs to oil cooler in metallurgy, power industry main equipment petrol station and leak detection thereof, craft leakage mending method, particularly a kind of Large-scale machine set lubricating oil station oil cooler and leak detection thereof, craft leakage mending method.
Background technique
Be the key ensureing that large equipment runs well at the lubricating oil station of metallurgy industry and power industry large-sized unit, do not have the equipment lubricated to run.The effect of lubricant oil is anti-attrition, heat of taking, and the effect of petrol station and oil cooler is fuel feeding, recovered oil and cooling recovered oil.The cooling liquid of oil cooler is generally softened water.Softened water usually supplies after oil cooler takes away heat and dispels the heat to cooling tower after pump pressurization, such circular flow reaches the object reducing oil temperature, usual water cooling tower directly dispels the heat to sky, the sand and dust in air are caused to be mixed in softened water, so long-term cycle operation causes the local of the copper pipe in oil cooler to grind leakage, oil leak is in cooling water, the few person 20 of copper pipe end face in oil cooler, many 50-60 roots, be difficult to determine leakage position, it is shut down process that row leaks ordinary circumstance, oil cooler integral replacing, have a strong impact on production, blast furnace blower generally shuts down 12 hours, Turbo-generator Set shuts down 16 hours, process once affects benefit 600,000 yuan, time-consuming.There is copper pipe mill thoroughly, as hydraulic pressure also can run lower than during oil pressure, waste lubricant oil, but timing repairing; Once generation hydraulic pressure higher than oil pressure, lubricant oil is mixed into water, and viscosity declines, unit bearing shell will all burn out, and large-sized unit breakdown loss is more heavy.Few person is up to a million, many ten million yuan.It is a great problem of metallurgy and power industry to the leak detection of oil cooler copper pipe and mending-leakage.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of Large-scale machine set lubricating oil station oil cooler and leak detection thereof, craft leakage mending method.It is convenient, fast, time saving and energy saving.
The present invention solves the technological scheme that its technical problem takes: the fixing oil inlet pipe of sealing and oil outlet tube on oil cooler shell body wall, oil cooler housing internal fixtion has cooling water copper pipe group, the two ends of cooling water copper pipe group seal fixing left and right sealing plate respectively, left and right sealing plate, copper pipe endoporus all for cooling water copper pipe group and copper pipe external series gap to be separated, copper pipe external series gap communicates with described oil inlet pipe and oil outlet tube, becomes oil duct; The two ends of oil cooler housing seal fixing left and right flanges respectively, and left and right flanges, the fixing cooling water outlet tube of upper sealing respectively and cooling water inlet pipe, cooling water outlet tube and cooling water inlet pipe seal with described all copper pipe endoporus and communicate, and become water channel.
The leak detection of Large-scale machine set lubricating oil station oil cooler, a craft leakage mending method, comprise the following steps: 1), oil cooler leak hunting method: first the water of oil cooler water outlet is sampled respectively and detects by an unaided eye, the proof oil cooler copper pipe leakage of oil that water sample oil bloom are many; 2), copper pipe group leak hunting method: the oil cooler water inlet road closing leakage of oil, whether oil circuit keeps unimpeded, and dismounting left and right flanges, exposes two ends copper pipe, then observe in two ends copper pipes and have oil to flow out, and the copper pipe having oil to flow out proves that oil divulged by mill, makes marks; 3), craft leakage mending method: cone blocking is inserted markd copper pipe two ends, rivet, guarantee firmly oil-proof again, install left and right flanges, water flowing.
The present invention is convenient, fast, time saving and energy saving, annual saving idleness expense more than 2,000 ten thousand yuan.
