Description
Technical field
The present invention relates to oil for electric power process and medicament adding technique, particularly to defoamer pretreatment adding set and method in a kind of oil.
Background technology
Foam characteristic is an important indicator of oil, forms the tendency of foam for evaluating oil and forms the stability of foam.In oil, foam exceeds standard the foam excess accumulation that can make in fuel tank, may work the mischief unit: containing bubble in oil, can accelerate the oxidative degradation of oil；Bubbles burst may cause governing system to vibrate, and causes noise and cavitation vibration；It is likely to result in oil pump cavitation；False liquid level may be caused, cause for shortage of oil, in some instances it may even be possible to foam overflow, cause oil leak accident；Foam is too much, and it is unstable that oil throttling is likely to result in oil pressure, makes electrichydraulic control signal misalignment.In the oil such as steam turbine oil, fire resistant oil, various subsidiary engine oil, foam characteristic exceeds standard, and hides some dangers for the safe operation of system and unit, possibly even cause stopping accident time serious, and the social influence caused and loss are difficult to estimate.Therefore, when in oil, foam characteristic exceeds standard, should take measures in time to process, adding defoamer be the preferred version of foam in the elimination oil generally acknowledged at present.
In defoamer adding procedure, if defoamer adds very few, then cannot play the requirement eliminating foam, if adding too much, oil quality may be impacted again, additionally, defoamer uniformly can not mix with oil after adding, it is also possible to makes the granule angle value of oil increase, affects the detection of oil product index.The most common defoamer addition manner mainly has two kinds: (1) traditional approach is manually to add, and is i.e. manually added a certain amount of defoamer when foam produces by manual type, and addition is difficult to control to；(2) use liquid feeding equipment or graduated equipment to be quantitatively adding, but due in oil product the addition of defoamer less, a small amount of additive is difficult to mix homogeneously with oil product, can not give full play to froth breaking effect, it is also possible to cause oil product granule detecting result higher.Therefore, the most accurately, uniform interpolation is that defoamer adds successfully key.
There is presently no and a set of be exclusively used in the apparatus and method that defoamer in oil adds, can realize accurately interpolation, mixed uniformly purpose, therefore, need badly and develop defoamer pretreatment and adding set and the method above-mentioned difficult problem of solution in a set of oil.
