Detailed description of the invention
As shown in Figure 1, 2, complete degasification when the utility model normally works according to the following steps and fill with oil work:
The first step: pipeline connects.Diaphragm seal pressure Transmitter body 4 is placed on travelling car 2, by oil-feed isocon 3 respectively with oil inlet A and diaphragm seal pressure transmitter teletransmission film head 5 compact siro spinning technology, again the branch road a-f of diaphragm seal pressure transmitter body 4 other end is tightly connected to fuel-displaced collecting pipe 6, the so far connection of completion system conduit.
Second step: airtight test.In the connection guaranteeing bellows 15 and vacuum pump 16 and extraction pipe 13 closely, blind off a line vacuum valve 9 and external vacuum valve 10, press start button 8 and open vacuum pump and start to vacuumize system.Whether the indicating value of observing suction gage 11 is according to about first reducing to be stabilized in a certain numerical value afterwards, if consistent with above-mentioned phenomenon, then explanation vacuum pump normally works and the equipment connection at bellows and its two ends is tight.Otherwise carry out checking air tightness of pipelines.
3rd step: silicone oil stirring degassing.Open pipeline vacuum valve 9, open magnetic force heating stirrer 12, to the silicone oil in oil storage bottle 14 under keeping vacuum pump 16 to be in the normal state run, and whole system pipeline vacuumizes.Can think that after suction gage indicating value is stablized the gas in silicone oil and system pipeline is fully drained.
4th step: vacuum reservoir oil.Continue after completing steps three to keep vacuum pump normally to run, unclamp oil storage bottle geometrical clamp 17, the silicone oil after removing bubble is poured into chargine line 18 from oil storage bottle 14, because pipeline is also continuing to vacuumize, therefore not needing to apply any external pressure just can by Silicone oil injection in diaphragm seal pressure transmitter body and teletransmission film head thereof.Be transparent pipeline owing to connecting the oil outlet a-f of transmitter and the pipeline of oil return collecting pipe 6, therefore, when pipeline has silicone oil to flow back in this section, then can think the teletransmission film head that this branch road connects and the oil-filled end of pressure transformer body.
5th step: recover pipeline to atmospheric pressure state.Press stop button 7, make vacuum pump out of service.Opening external vacuum valve 10 makes whole pipeline system be connected with air, guarantees to make diaphragm seal pressure transmitter body and capillary tub and teletransmission film head thereof evenly, fully be filled with silicone oil under atmospheric pressure.The connection of opening pressure transmitter teletransmission film head 5 and oil-feed isocon 3, the simultaneously connection of a-f in fragmentary 1.So far the filling oil to diaphragm seal pressure transmitter is completed.
