Description
Technical field
The utility model relates to a kind of sampler, relates in particular to a kind of oil film water cut sampling detecting device to the backing roll of milling train that is applied in the hot rolling production run.
Background technology
At present; In the steel rolling production run of steel production industry; Because take the spray application of a large amount of chilled waters, can cause part water being mingled with certain brown iron oxide and washed away in the entering backing roll film lubrication chamber, and because the closed-loop system that this film lubrication system itself is self-loopa; Then the lubricating oil in the film lubrication chamber can flow back in the fuel tank through the return oil system pipeline, and the potpourri that had wherein before been washed away water, the brown iron oxide of entering is also accompanied together and flowed back to fuel tank; The result that this phenomenon causes is the liquid level of the fuel reserve tank of backing roll oil film system constantly rise (water cut is gathered and caused); Simultaneously; The strainer screen of the gear-type pump outlet of output system lubricating oil stops up because of foul gathers; So can cause the system oil delivery rate little, not have well and lubricate, lower the temperature, resist the load protective effect.
And in the actual maintenance process, the water cut that in backing roll film lubrication chamber, gets into hour can be through the regular floss hole draining of fuel tank, the switching of strainer screen, cleans the harm of resisting above-mentioned hidden danger; And in fact; If in case because of the wearing and tearing aggravation of backing roll oil film seal or install when not in place; Can cause the chilled water that is being mingled with brown iron oxide in a large number to wash away passively and get in the backing roll film lubrication chamber, thereby further be back in the fuel tank again, because water cut big (meaning that the brown iron oxide of sneaking into fuel tank synchronously is also more) in the system oil return; Can cause the strainer screen frequent jams of the gear-type pump outlet of output system lubricating oil, report to the police; When obstruction is serious, directly cause the system output stream amount too small, situation is serious, can cause the oil film sliding bearing because of flow of lubrication scaling loss, the accident of breaking-up to take place inadequately.
In addition, the gear-type pump of oil film system also can be because of a large amount of water, brown iron oxide and the oily stirring that mixes in continuous operation process, and causes pump bearing to peel off, damage because of the ball face takes place for continuous high temperature, overload, poor lubrication; Jump the pump accident.Above-mentionedly either way can cause being forced to stop production of production line, for a long time the machine halt trouble processing time, lose big seeing some from this.And usually in the steel rolling production run; If take place above-mentioned oil tank liquid level rise very fast (because of the unusual inflow of fuel tank more); During situation such as the frequent pressure reduction warning of pump discharge filtrator; Because lack necessity and water cut detection easily, sampler; Then can't judge fast is that measure comes emergency processing thereby can't further take targetedly, the too passive situation when having caused abnormal problem to occur because of the unusual more appearance that causes a hidden trouble of inflow in which backing roll film lubrication chamber; Even have to sometimes that backing roll is passive deals with processing through changing on a large scale, so all can bring big negative effect to the production schedule ground smooth execution of original layout, control, output and the benefit etc. of time cost.
So press for a kind of novel sampler at present; Can take a sample to the oil film water cut of hot-rolling mill backing roll, help the field device maintenance personnel accurately to judge as soon as possible to be the unusual inflow in which backing roll film lubrication chamber more, on this basis; The content of visual unusual inflow how much; Determine whether existing the backing roll of hidden danger to carry out resolute replacing fast, avoid the further extension of contingency question ground, and potential problem is thoroughly solved this.
The utility model content
For improving the problem that exists in the prior art; The utility model provides a kind of oil film water cut sampler of hot-rolling mill backing roll, and this device installation application is convenient, and the determination methods of potential problem is also quite easy; The principle of determination methods: through of the sampling of sample valve piece to backing roll oil film system oil return pipeline; With oil in the return line, aqueous mixtures together collects in the oil-feed cup, then according to the physical characteristics of oil, water, because of the density of oil littler than the density of water; When their potpourri is put a period of time in lubricating cup after; Lamination can occur, oil film oil can significantly float over the upper strata, and lower floor is exactly water (containing micro-brown iron oxide) near white stratified liquid; And will judge is that unusual inflow is more for a long time in which backing roll film lubrication chamber; Then can the lubricating cup of a plurality of equivalent samplings be put together; Wait then in the cup after the thorough layering of potpourri; But visualization is when wherein the lower floor's water cut liquid volume accounting in which lubricating cup is big, and just can judge fast is that unusual potential problem has appearred in which backing roll.The concrete structure of the utility model is described below:
