Detailed Description
Interpretation of terms:
① reference point, the point where the perpendicular drawn from the dipstick point intersects the can bottom metering platform, is also called zero point.
② Scale Point-the point at which the edge of the scale mouth is fixed to the lower scale.
③ altitude is the distance from the dipstick point to the liquid level in the tank.
④ ruler for direct measurement is the distance from the liquid level in the container to the reference point by using a dip rod, which is the most basic method for manual ruler measurement and the most daily used method for ruler measurement.
⑤ empty measuring rule, measuring the empty height from the point of the rule to the liquid level in the tank.
The present invention will be further explained with reference to fig. 1 to 3:
as shown in fig. 1, the oil position metering device comprises an oil dip rod 4 and an oil tank 1, wherein the oil dip rod 4 comprises a rod disc, a rod belt 41 and a rod hammer 44, scales are marked on the rod belt 41, one end of the rod belt 41 is connected with the rod hammer 44, one end of the rod belt 41 is wound on the rod disc, and the rod disc rotates to release or retract the rod belt 41; a dipstick mouth 3 is arranged on the top of the oil tank 1, the dipstick mouth 3 can observe the liquid level 2 of oil in the oil tank 1, a tape 41 and a tape hammer 44 of an oil dip rod 4 enter the oil tank 1 through the dipstick mouth 3, and a tape disc is fixed around the dipstick mouth 3 through a bracket. The blade mounts a handle which is swung to rotate the blade to release or retract the blade 41.
The measuring steps of the metering device for the oil product position are as follows:
1. after the dip rod is lowered, an operator pays attention to observe the liquid level condition in the oil tank 1 through the dip rod opening 3, slowly shakes the handle to ensure that the falling speed of the dip rod hammer is not more than 1m/s, sees the shaking of the oil product liquid level, stops the dip rod after confirming that the dip rod hammer contacts the oil level, retracts the crank, slightly lifts the dip rod belt up and down, estimates the depth of the dip rod hammer entering the liquid level, and reads the dip rod height of the dip rod 4 at the dip rod point. The liquid level fluctuation caused by slightly lifting and pulling the ruler belt can be leveled within 3-5 seconds generally, and the fluctuation image can be seen to be quickly restored to be calm by observing the shadow on the liquid level through the ruler hole, so the operation does not influence the integral metering precision.
2. The approximate height of the oil surface can now be calculated: hy = H-H1+ H2.
In the formula: hy-liquid level height;
h-reference height of oil container (base height);
h1-height of the oil dip rod below the scale point;
h2-height of the submerged portion of the dipstick tape or hammer by the liquid surface.
3. And continuously putting the ruler until the ruler hammer contacts the bottom of the tank, lifting the ruler as required, searching for the oil mark near the liquid level estimated on the ruler belt, wherein the range cannot exceed ten centimeters under general conditions, the ruler belt can be turned over to see the back side if the front side of the ruler belt is not clear, the back side is easy to find the position of the oil mark due to no scale, and reading and recording are carried out to complete the first ruler checking operation.
4. When the second scale checking operation is carried out, because the position of the oil mark is known, the step can be omitted, the scale is directly placed to the bottom of the tank, the time is saved, and the efficiency is improved.
In brief, when measuring the height of light oil, the height from the mouth of the gauge to the oil surface is recorded, and then the height is subtracted from the total height of the gauge to calculate the approximate height of the liquid level in the tank. And (4) continuously putting the ruler for measurement, lifting the ruler according to the specified requirement, searching for oil marks near the approximately calculated liquid level height in advance, and finishing reading and metering. The operation can effectively avoid the problem that oil marks can not be found when light oil products are measured, and the requirement of light oil operation guide rules is met without violently lifting the quick-pull oil measuring ruler.
In daily scale operation, the full scale and the empty scale are both used for measuring conveniently, and have no large limit, and the final purpose is that an operator can complete measurement safely, efficiently and accurately. The heavy oil detection empty ruler and the light oil detection actual ruler are generally used, but can be flexibly applied according to the working actual conditions of people. In practical production, for example, when a heavy oil tank water gauge is used, if the oil tank is not cleaned for a long time, impurities are carried at the bottom of the tank, and the gauge hammer is difficult to hit the bottom of the tank. When the ruler hammer is difficult to drop, the ruler tape is clamped for reading, and the height of the lower ruler is remembered. After the water gauge is measured, the difference between the height of the water gauge and the height of the lower ruler subtracted from the total height of the detection ruler is not forgotten, namely the actual height of the water gauge, and the actual height is changed by using the method of detecting the empty ruler. And impurities are at the bottom of the light oil tank, the ruler hammer can not hit the bottom of the tank, and the empty ruler can be detected.
The full scale and the empty scale are properly used, so that the actual metering problem in production can be solved, but the following points are also noted:
firstly, the total height of the measuring ruler must be known before the measuring ruler, and the full ruler can be compared with the height of the lower ruler to determine whether the ruler hammer really touches the tank bottom, so as to check whether the oil tank is deformed or not and whether sundries exist at the tank bottom or not. The method is more indispensable for detecting the empty ruler because the method is used for converting the actual oil height.
And secondly, when the ruler is drawn down, the ruler belt is required to be closely attached to the ruler checking point. This has three benefits, first, preventing the tape from wobbling in the jar. Second, the drop speed of the hammer can be controlled during the tape laying process. Third, effective electrostatic grounding can be achieved.
And thirdly, when the oil mark is searched, an included angle of 45 degrees can be formed between the ruler belt and the sight line, the ruler belt can be swung during reading, the position of the oil mark can be found by means of light refraction, two eyes need to be perpendicular to the ruler belt scale reading, the millimeter is read firstly, and then the numerical values of the centimeter, the decimeter and the meter are determined.
Fourth, regardless of the inspection method, it is important to note that the inspection methods for the same tank should be consistent during an inspection cycle. For a finished product oil tank, the process is measured by a measuring method of a full scale from the beginning of oil filling of an empty tank to the end of finished product payment, and the measuring method of the empty scale is not used, so that the system error of measurement is not increased.
As shown in fig. 2 and 3, in order to overcome the rapid volatilization of the oil mark on the dip stick, the specific position of the oil mark on the dip stick cannot be determined.
The tape 41 is a cylindrical body, an installation groove 42 is formed in the tape 41, a rubber strip 43 is arranged in the installation groove 42, and the rubber strip 43 is corroded when contacting oil. Through setting up the rubber strip 43 that is corroded by the oil easily for the rubber strip of chi area oil trace below can be corroded by the appearance of different degree, and easily by the naked eye observation, thereby accurate definite oil trace position, and need not worry about disappearing fast of oil trace, ensure the precision of measuring.
The mounting groove 42 is located along the inside of the tape 41 from the surface of the tape 41, and the height of the rubber strip 43 is greater than the depth of the mounting groove 42 so that a portion of the rubber strip 43 is located inside the mounting groove 42 and another portion is located outside the mounting groove 42. The rubber strip 43 and the mounting groove 42 are of a detachable structure. The rubber strips 43 are multiple, and the rubber strips 43 are connected end to end and arranged in a line to be installed in the installation groove 42.
In order to save the use of rubber strips, only the corroded rubber strips need to be replaced each time the measurement is carried out, and the rubber strips which are not corroded can be continuously used. Meanwhile, the rubber strip extends outside the tape, so that the corroded rubber strip can be detached by tearing, and replacement is convenient.
The present invention has been described in detail with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above embodiments, and various improvements of the method concept and the technical solution of the present invention can be made without modification, or the present invention can be directly applied to other occasions without modification, and is within the protection scope of the present invention.
