Problems solved by technology

[0004] The purpose of the present invention is to provide a method for improving the accuracy of measuring the oil height in the oil tank, so as to solve the problem that when the external temperature is low, the temperature of the oil in the ruler tube will be low and the density will increase, causing the liquid level in the gauge tube to be lower than that in the tank The phenomenon of the liquid level, so that the actual measured volume is smaller than the real volume of the oil in the tank, resulting in a certain error problem

Embodiment 1

[0035] Such as Figure 1-Figure 2 As shown, the present invention improves the method for measuring the accuracy of the oil height in the oil tank, comprising the steps of:

[0036] Step A verification: verify the dipstick, and correct the tape 3 according to the verification result;

[0037] Step B heating: start the energy supply device 8, so that the heating device 7 performs the heating operation;

[0038] Step C heat dissipation: start the driving device 6, make the blowing device 5 located in the air guide tube assembly start to work, pass the air around the heating device 7 through the blowing device 5 through the opening of the air guide tube assembly, and blow to the tape 3;

[0039] Step D Open the cover and measure: when the temperature of the tape 3 and the air around the oil measuring port of the oil tank is consistent with the temperature of the oil in the tank, open the cover of the oil measuring port, and hold the handle connected to the oil dipstick frame 1 ...

Embodiment 2

[0043] The present invention is based on embodiment 1, and the present invention is further described.

[0044] Such as Figure 1-Figure 2 As shown, the present invention improves the method for measuring the accuracy of the oil level in the oil tank. The air guide tube assembly includes the installation tube 9, the horizontal tube 10 and the guide tube 11 which are sequentially communicated in the inner cavity. One end of the installation tube 9 Vertically connected to the handle 2, the other end of the installation cylinder 9 is connected to the guide cylinder 11 through the horizontal cylinder 10, and the axis of the horizontal cylinder 10 is parallel to the axis of the handle 2, and the axis of the guide cylinder 11 is parallel to the axis of the installation cylinder 9, And the end of the guide cylinder 11 away from the horizontal cylinder 10 faces the tape 3;

[0045] Both the blowing device 5 and the driving device 6 are located at the end of the inner cavity of the in...

Embodiment 3

[0048] The present invention is based on embodiment 1, and the present invention is further described.

[0049] Such as Figure 1-Figure 2 As shown, the present invention improves the method for measuring the accuracy of the oil height in the oil tank, the blowing device 5 is a fan, and the driving device 6 is a clockwork device, and when the coiled steel bar of the clockwork device is unclamped, the fan's The fan blades rotate.

[0050] Open flames and the activation of ordinary electronic equipment are prohibited around the oil tank to avoid contact with air when the electronic equipment is activated, which may cause a fire. Setting the driving device 6 as a clockwork device avoids sparks when the motor is started and ensures the safety of the staff.

Abstract

The invention discloses a method for improving the measurement accuracy of the height of oil in an oil tank. The method includes the following steps: a step A, verifying an oil dipstick; a step B, starting an energy supply device, and allowing a heating device to give out heat; a step C, starting a driving device, allowing an air blowing device positioned in an air guide barrel assembly to start to work; and a step D, opening a cover of an oil measurement opening when the temperature of a stick band and the temperature of air around the oil measurement opening of an oil tank are consistent with the temperature of oil in the oil tank, and putting a stick lump in a verification tube so as to allow the stick band to fall down under the drive of the stick lump. The air around the oil measurement opening is heated, the temperature around the oil measurement opening is increased, the phenomenon that after the measurement opening is opened, overlarge temperature difference between an inner part and an outer part of an oil tank causes the low temperature and increased intensity of oil in a pipe, and a liquid level of a pipe is lower than a liquid level of the tank can be avoided, the actually measured volume is equal to the real volume of the oil in the tank, and the oil dipstick can avoid measurement errors of the height of the oil in the tank.

Description

technical field [0001] The invention relates to a method for measuring the height of oil in an oil tank, in particular to a method for improving the accuracy of measuring the height of oil in an oil tank. Background technique [0002] At present, in the trade measurement of domestic petroleum products, oil tanks are usually the main oil storage devices that need to be measured. The measurement of oil products is affected by many aspects, such as the accuracy of the measurement tool, the temperature of the oil, the volume of the oil, etc. During the custody transfer process of petroleum and its liquid products, the main gauges used must be periodically calibrated in accordance with regulations to give correct correction values. [0003] In the height measurement of the oil tank, the ruler is generally lowered in the ruler tube of the gauge hole, and the position of the gauge tube is generally set at 500-1000mm near the closure, which is greatly affected by the ambient temper...
