Two, background technology
At present, accurately the method for the general employing in position of water-oil interface is to measure total fluid pressure in the jar with pressure transducer at the bottom of the jar in the measurement jar, and then to the height of tank deck with dipping measurement pasta, the density according to oil, water calculates the height of water-oil interface with the method for dividing potential drop at last.And be directly on jar, to estimate interfacial level with dipping under a lot of situations.Another kind of common method is according to the difference of oil, water resistance rate, manually directly measures pot liquid resistance variations situation at the roof opening place with multimeter, thus estimation water-oil interface height.These methods exist following shortcoming or deficiency: 1. have observational error, measuring accuracy is low, and need manually repeatedly climb up tank deck and finish this work, and labour intensity is big; 2. have hidden danger, especially have certain danger winter, the jar that has has a large amount of profits to come in and go out every day, and the workman also must pay close attention to and excessive jar possibility occur.
Three, summary of the invention
The purpose of this utility model provides a kind of water-oil interface measuring instrument, adopts photoelectric code disk counting and Computer signal to handle, and can directly show the water-oil interface height, and the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art improve measuring accuracy.
Water-oil interface measuring instrument described in the utility model, comprise slurry tank, ball float, sealing-plug, leading block, steel band, constant force spring, steel band folding and unfolding wheel mechanism, support, bearing housing, photoelectric code disk, cable, the signal Processing show case, described leading block is installed on the slurry tank top, ball float is arranged at the water-oil interface place in the slurry tank, described steel band folding and unfolding wheel mechanism is installed on the outer ground of slurry tank, comprise the folding and unfolding wheel that is installed on the folding and unfolding wheel shaft, the support of installing on this folding and unfolding wheel end mounted bearing case and the bearing housing, described constant force spring one end is fixed on the folding and unfolding wheel, the other end twines the back and links to each other with steel band on the folding and unfolding wheel, the other end of steel band links to each other with the sealing-plug of ball float through leading block, described photoelectric code disk is installed on the folding and unfolding wheel shaft, and its output terminal links to each other with the signal Processing show case by cable.
Described ball float is positioned at slurry tank water-oil interface place, which is provided with a hole that communicates with inner chamber, and the sealing-plug that this Kong Youyu steel band is connected seals mutually, and the liquid or the grains of sand that make ball be in the water-oil interface place are housed in the ball.
The utility model has following advantage compared with prior art:
1, measuring accuracy height by the photoelectric code disk change in count that the ball float change in location causes, can accurately calculate the water-oil interface height.
2, intelligent degree is higher, adapts to the needs of oil-gas gathering and transportation automatic management.
3, measure conveniently intuitively, labor intensity of operating staff is low.
4, safety coefficient height, no potential safety hazard.
Four, description of drawings
Fig. 1 is a kind of structural representation of the present utility model,
Fig. 2 is for pressing steel band folding and unfolding wheel construction synoptic diagram shown in Figure 1.
Five, embodiment
Consult Fig. 1-Fig. 2, a kind of water-oil interface measuring instrument, comprise slurry tank, ball float, sealing-plug, leading block, steel band, constant force spring, steel band folding and unfolding wheel mechanism, support, bearing housing, photoelectric code disk, cable, the signal Processing show case, leading block 3 is installed on slurry tank 13 tops, ball float 1 is arranged at the water-oil interface place in the slurry tank, steel band folding and unfolding wheel mechanism is installed on the outer ground of slurry tank, comprise the folding and unfolding wheel 5 that is installed on the folding and unfolding wheel shaft 12, the support of installing on this folding and unfolding wheel end mounted bearing case 7 and the bearing housing 6, constant force spring 11 1 ends are fixed on the folding and unfolding wheel, the other end twines the back and links to each other with steel band 4 on the folding and unfolding wheel, the other end of steel band 4 links to each other with the sealing-plug 2 of ball float 1 through leading block 3, photoelectric code disk 8 is installed on the folding and unfolding wheel shaft 12, and its output terminal links to each other with signal Processing show case 10 by cable 9.
Ball float 1 is positioned at slurry tank 13 water-oil interface places, which is provided with a hole that communicates with inner chamber, and the sealing-plug 2 that this Kong Youyu steel band is connected seals mutually, is equipped with in the ball to make ball be in oily 14 water 15 liquid or the grains of sand at the interface.
Owing to will measure the water-oil interface height, therefore must make ball float 1 float over bigger waterborne of density, be immersed under the smaller oil of density, promptly be positioned at the water-oil interface place.Because therefore oil, water-mass density substantially constant in jar can calculate the buoyancy that ball float 1 is subjected in You Heshui.In order to make ball float 1 be applicable to different oil, water-mass density, should make its weight can be by the counterweight adjustment.In ball float 1, add an amount of liquid or sand by circular hole, make the ball float 1 that adds liquid or sand be centered close to oil water surface place in the slurry tank, with sealing-plug 2 ball float 1 is sealed again.
During use, at first photoelectric code disk 8 is carried out scale, determine its resolution ratio, i.e. the height change of each pulse correspondence.According to the length of steel band 4, determine initial liquid-level interface height then.When water-oil interface rose, ball float 1 rose thereupon, and steel band 4 is loose, and constant force spring 11 tightens, and steel band folding and unfolding wheel 5 is moved in the direction of the clock, and photoelectric code disk 8 rotates by same direction; When water-oil interface descended, ball float 1 descended, steel band 4 tensions, and constant force spring 11 extends, and makes steel band folding and unfolding wheel 5 by counterclockwise rotating, and photoelectric code disk 8 rotates by same direction.Change in location along with ball float 1, a series of pulse signals of photoelectric code disk 8 outputs are given signal Processing show case 10 through cable 9, signal Processing show case 10 at first carries out shaping to these signals, paired pulses is counted then, obtain the height change of ball float 1 again according to the resolution ratio of photoelectric code disk 8, in conjunction with the initial interface height, calculate and demonstrate the pot liquid interface location again.
