Description
Technical Field
The invention relates to the technical field of chemical pressure vessels, in particular to a liquid level measurement process method of a deep-cold pressure vessel.
Background
Liquid level measurement can be generally divided into two methods, direct measurement and indirect measurement. Direct measurement is the simplest and intuitive measurement method, which uses the principle of a communicating vessel to introduce liquid in a container into an observation tube with a scale, and reads the liquid level through the scale. Indirect measurement is to convert the liquid level signal into other related signals for measurement, such as a pressure method, a buoyancy method, an electrical method, a thermal method and the like. The measuring device for the liquid level height comprises a differential pressure type liquid level meter, a glass tube liquid level meter, a floating ball liquid level meter, a rotary tube liquid level meter and the like.
The most widely used liquid level measuring devices in today's low temperature pressure vessels are: double corrugated pipe combined differential pressure type liquid level meter. The differential pressure type liquid level meter is provided with two pressure taking ports of gas phase and liquid phase. The gas phase pressure taking port is positioned in the gas phase space at the uppermost end of the container and receives gas phase pressure; the liquid phase pressure taking port is positioned at the bottommost end of the tank body, and the liquid phase pressure is under the action of the hydrostatic pressure of the liquid column besides the gas phase pressure, namely the hydrostatic pressure of the liquid column. In general, the density and the gravitational acceleration of the medium to be measured are known, and therefore, the pressure difference measured by the differential pressure gauge is proportional to the height H of the liquid, which changes the problem of measuring the height of the liquid into the problem of measuring the differential pressure. The unit of the measuring range of the combined differential pressure type liquid level meter is kPa or millimeter water column, the liquid level height of the medium in the inner container can be known through conversion according to the reading, and the volume, the mass and the like of the residual medium can be converted.
Because the liquid level difference H exists between the bottommost end of the inner container and the liquid phase end of the liquid level meter, if the liquid with a certain height exists in the liquid phase pipe of the liquid level meter, the situation that the pressure of the liquid phase end of the liquid level meter is smaller than the pressure of the bottommost end of the inner container can occur; if the liquid level in the liquid phase pipe of the liquid level meter is lower than the horizontal line at the bottom end of the inner container, the situation that the pressure of the liquid phase end of the liquid level meter is higher than the pressure of the bottom end of the inner container can occur.
The differential pressure liquid level meter is used for measuring differential pressure, and the diameter of the tank body of the cryogenic tank car is not more than 2500mm, so that the differential pressure is relatively small, and even if the pressure in the tank body fluctuates slightly, the differential pressure is large relative to the differential pressure. The liquid level meter can be read to be fluctuated during loading and unloading, and measurement is inaccurate.
The above deficiencies can cause errors in the measurement of the level gauge. Because the environment is variable, when the differential pressure type liquid level meter is used, if corresponding measures are not taken in design, the situation that the liquid level of the low-temperature liquid in the container is unchanged and the reading is inaccurate occurs. Therefore, the invention discloses a liquid level measurement process method of a deep-cold pressure container.
