Description

Novel liquid quantitative filling device

Technical Field

The invention relates to the field of fluid quantitative control, in particular to a novel liquid quantitative filling device.

Background

A fluid is a flowable substance, which is a body that deforms continuously under any slight shear force. Fluids are a generic term for liquids and gases. It has easy flowability, compressibility and viscosity. The fluid composed of a large number of molecules which do continuous thermal motion and do not have fixed equilibrium positions has certain compressibility, the compressibility of the liquid is small, the compressibility of the gas is large, and when the shape of the fluid is changed, certain motion resistance exists between each layer of the fluid.

When the viscosity and compressibility of the fluid are small, the fluid can be approximately regarded as an ideal fluid, which is an ideal model introduced for researching the motion and state of the fluid and is a medium for hydraulic transmission and pneumatic transmission.

Solids and fluids have the following different characteristics: the solid body can simultaneously bear shear stress and normal stress on an action surface in a static state. The fluid can have the effects of normal stress and tangential stress only in a motion state, and the acting surface of the fluid can only bear the normal stress in a static state, and the stress is compressive stress, namely static pressure. The solid body deforms under the action of force, and hooke's law is obeyed between deformation and action force within the elastic limit, namely the deformation amount of the solid body is in direct proportion to the magnitude of the action force. The fluid is related to angular deformation speed and shear stress, the relationship between laminar flow and turbulent flow is different, and Newton's internal friction law is obeyed between laminar flow and turbulent flow. When the force ceases, the solid can return to its original shape and the fluid can only cease to deform and not return to its original position. The solid has a certain shape, and the fluid can easily adapt its shape to the shape of the container because the shearing force required for deformation of the fluid is very small, and can be maintained under certain conditions.

The common filling device directly injects oil, and the added oil is not quantified, so that the oil is not filled accurately, and the equipment is easy to inject the oil due to misoperation; and the warning light of the device is easily damaged when being outside for a long time, thereby influencing the use.

In view of this, we propose a novel liquid quantitative filling device.
