oil dipstick

[Mengjuan Zhu]

The measuring rod part of the oil gauge generally has three structures: steel wire, steel belt (Bian Chi), and many winding wires. Among them, spring steel wire is commonly used in steel wire structure, and the material is hard, which is suitable for the relatively slow bending ruler tube. The multi strand wire is easy to insert and plugged in the bending scale tube, but the price is higher. The material of flat ruler generally chooses 0.8mm~1.2mm stainless steel strip, and the price is relatively low. As the core part of the ruler, the head of a ruler is the most important part of the ruler. In the drawing, it is easy to rub with the ruler tube that matches with it. The particles produced by the friction will fall into the lubricating oil. The unclean lubricating oil will cause great wear to the bearings of the engine. In the indicator part of the scale, the head can be designed as a roller structure, which is not only effective. The scale has reduced the tube pulling force of the ruler and reduced the scraping of the ruler head and the ruler tube.

For the oil gauge with steel strip structure, in order to make the gauge clearly indicate the position of the liquid level, it is easier for users to read the oil gauge. Generally, the head of the flat ruler is treated with sand blasting or press mesh, and some rhombic pits can be set on the head of the plastic. These pits are disconnected from each other, so that the oil can climb up the trough under the siphon effect, which affects the accurate reading of the scale.
