People who regularly use dipsticks should know that dipsticks are special tools used in oil metering to measure the depth and height of oil in containers. The dipstick has the advantages of convenient operation and small error, and it is suitable for measuring the depth (real height) of the oil in containers such as oil tankers and oil storage tanks or for measuring the depth of the water level at the bottom of the container. Xiao Bian today explained how to use the dipstick, its technical requirements and structure.
　　 How to use the dipstick (using the lion dipstick as an example)
The first step: the product is extracted from the box;
The second step: adjust the oil drop and ruler to a straight line and turn the handle over.
The third step: Hold the dipstick handle with your left hand and hold the handle with your right hand;
Part IV: Let the oil drop fall freely. Because the gravity of the oil fall can speed up the falling of the ruler, the hand holding the handle must relax properly;
Step 5: Use the crank to control the downward speed of the gravity of the oil drop. When the oil drop touches the bottom of the container, the left hand grips the handle net to extract and keep the ruler in the solution.
Step 6: Take out the measurement and use the handle to shake the ruler to the ruler;
Step 7: Observe the color change of the page and read the reading on the liquid surface. This can be used to measure the liquid depth.
Step 8: After reading a book, slowly roll the ruler into the frame, wipe the tape with a clean veil, and place it in the packing box after use.
　　 Dipstick technical requirements
(1) The surface of the dipstick must be clean and free of spots, rust, kinks, and other defects; the edges should be smooth and there must be no sharp edges or barbs.
(2) All ruled lines must be uniform, clear, and perpendicular to the edge of the strip.
(3) The reticle representing the decimeter and the meter must traverse the surface. The scribe lines representing centimeters, 0.5 centimeters, and millimeters should be longer than one.
(4) The dipstick to be used shall be regularly verified. The verification certificate shall be accompanied by a correction value per meter.
　　 Dipstick structure
Speaking of the structure of the dipstick, it is actually very simple: the dipstick is composed of a handle, a ruler, a crank, a ruler, a ruler, a lock, an oil wiper, a bracket, and a connector. The dipstick's scale direction Head towards the handle. The locker utilizes a lock switch, a pin, and a spring to position the lock cylinder of the measuring rod, and the oil wiper is hung on the fixed pulley on the scale frame. The oil dipstick passes through the felt of the oil wiper and will be attached during measurement. Scrape the oil. One-way ratchet clutch structure is used for the crank to make the dipstick fall automatically by the weight of the caliper. The bracket is a folding metal bracket with a card slot at the bottom to facilitate the support of the dipstick and electrostatic discharge.
The dipstick connects the ruler to the ruler with a hook. It has a cylindrical or prismatic shape with a circular platform at its lower end, and its bottom end is the zero point of the dipstick. Therefore, the ruler and the rotating rotary hook must be fixed and cannot be replaced or loosened. A drum and a shaft are mounted on the frame, and one end of the shaft is connected to the crank. The role of the handle is to roll the ruler on the drum, and the nominal length of the dipstick is engraved on the handle. The scale of the test ruler should be wiped clean, and the water and grease should be evenly applied to the tape. The position of the application can be estimated based on the water and oil level. After smearing the test water and ointment, according to the requirements of the measurement, the oil meter housing is put into the oil to be measured. After the oil dipstick to be tested is stable, the oil dipstick is proposed, and the position of the oil or oil surface can be observed. The place where the water or ointment is in contact with is red. After the oil dipstick is proposed, it cannot be tilted down before the water or oil level is observed, so as to prevent the oil from flowing on the dipstick band and affect the accuracy of the measurement.
The above is the entire content of the method, technical requirements and structure of the dipstick used by Xiaobian for everyone's explanation. Dipstick is a professional measuring instrument, usually made of black nickel and stainless steel feet to measure the depth of oil reserves, oil wells, tankers and so on. There are many kinds of dipsticks, such as the dipstick of crude oil, the dipstick of automobile, and many other dipsticks. However, the material is basically a carbon steel dipstick and a stainless steel dipstick.
