Description
Technical field
The utility model relates to manometer vacuum oil filling technical field, is a kind of S. A. vacuum oil filling machine specifically.
Background technology
Vacuum oil filling technology is an important manufacturing process technology in manometer industry, and it is widely used in barrier film junctor, long-tail diaphragm sensor and the long-tail barrier film pressure switch etc. of barrier film manometer, long-tail remote transmission instrument, hygiene-type junctor manometer, the high static pressure differential pressure gauge of two diaphragm, all types of materials.Existing vacuum oil filling technology relies on special oil-filled equipment---and vacuum oil filling machine is realized.Whether the structure of vacuum oil filling machine is reasonable, the quality that isolated chambers is oil-filled, and whether the degree of vacuum vacuumizing is higher, all directly affects the product design of instrument.
The structure of traditional vacuum oil filling machine as shown in Figure 1, is broadly divided into three parts: vacuum pump 1, oil-filled stand 2 and be provided with the oil-filled tank 3 of aie escape valve 6.Its oil-filled principle of work is as described below:
Open the lid of oil-filled tank 3, Medium Oil 4 is poured into oil-filled tank 3, then will treat that oil-filled instrument 5 puts into oil-filled tank 3, guarantee that Medium Oil 4 submergences treat oil-filled instrument 5, close the lid of oil-filled tank 3, close the aie escape valve 6 on oil-filled tank 3; Then open vacuum pump 1, oil-filled tank 3 is vacuumized to half an hour, treat that air in the inner chamber (inner chamber is isolated chambers) of oil-filled instrument 5 is drawn out of to enter into Medium Oil 4, final air is discharged from; Then close vacuum pump 1, open aie escape valve 6, air enters the interior compressing Medium Oil 4 of oil-filled tank 3 and enters in the isolated chambers for the treatment of oil-filled instrument 5, oil-filled complete; Then open the lid of oil-filled tank 3, from Medium Oil 4, take out oil-filled complete instrument, the oil-filled jackscrew in instrument is tightened, even if completed operation.
There is following defect in traditional vacuum oil filling machine:
1, Medium Oil 4 purity (purity refers to air residual in Medium Oil) are inadequate, and internal gas (air in Medium Oil) is not fully separated out, and easily affects oil-filled quality.
Vacuum oil filling machine is to treating filling medium oil vacuumizing phase in oil-filled instrument 5, in Medium Oil, air is residual in addition, in the time that the oily instrument of substituting the bad for the good is worked use afterwards, air can be separated out from Medium Oil, in isolated chambers, form bubble, because coefficient of thermal expansion and the pressurized shrinkage percentage of Medium Oil are very little, and the coefficient of thermal expansion of air and pressurized shrinkage percentage are very large, at the higher environment of temperature, in the larger situation of the environment that temperature is lower or pressurized, can make displacement and the very large error of linear appearance of instrument isolation diaphragm, thereby affect the pointing accuracy of instrument, in serious situation, instrument just can not have been used at all.
2, degree of automation is not high, pure manual operation, inefficiency.
Because traditional vacuum oil filling machine is pure manual operation, there is no degree of vacuum detecting devices, to only have the cover of oil-filled tank 3 to be provided with the vacuum indicator that resolution is very low and can look at vacuum pressure value roughly, the position of arriving of taking out for vacuum, has no way of finding out about it.Can only lean on to vacuumize a period of time more and ensure, so just greatly extend the production cycle, thereby reduced production efficiency, and degree of vacuum do not ensure, cause the unstable of product design.
3, labor intensity of operating staff is large, and it is difficult that environmental health keeps.
The inside of oil-filled tank is darker, and instrument is put into and taken out all needs very large muscle power, and take out be to take a lot of excess oil out of, virtually increased again the weight of instrument, personnel and external environment condition are also easily polluted.
