Lubrication method of oiling device
Liquid lubrication of oiling devices can be further divided into liquid lubrication (see Lubricants and Liquid Lubricants). Lubrication is divided into fluid lubrication and boundary lubrication. The lubrication state between fluid lubrication and boundary lubrication is called mixed lubrication or partial elastic hydrodynamic lubrication.
Oiling device under the appropriate conditions, two friction surfaces can be separated by a certain thickness (1.5-2μm) of viscous fluid, and balance the external load by fluid pressure. Most of the molecules in the fluid layer move freely on the friction surface without the influence of ionic electric field, i.e. friction exists only in the lubricated state between fluid molecules.
The coefficient of friction of fluid lubrication of oiling devices is very low (less than 0.01). Fluid lubrication can be divided into dynamic pressure lubrication and static pressure lubrication according to the way of generating oil film pressure. In the traditional study of lubrication mechanics, the friction body and lubricant are considered as rigid body and viscous fluid (Newtonian fluid). The friction body is actually an elastomer, but sometimes it can be reduced to a rigid body.
Oiling device elastomeric lubrication is a hydrodynamic lubrication that needs to consider the effect of elastic deformation and pressure on viscosity. When the friction body is in a plastic state, the hydrodynamic lubrication with plastic effect is called plastic hydrodynamic lubrication. The traditional research method of fluid lubrication began in 1886 in England, O. Reynolds. traditional lubrication mechanics research results are called classical lubrication mechanics. In fluid lubrication, the viscosity of the fluid is usually measured by its viscosity.
The relationship between the shear stress of the oiling device and the velocity gradient (the rate of change of the fluid velocity u along the direction Y perpendicular to the laminar flow direction) is expressed by an equation, where n is the proportionality constant, i.e., viscosity, also known as dynamic viscosity. The above relationship is called the law of internal friction of fluid laminar flow, also known as Newton's law of internal friction. The fluid that conforms to this law is called Newtonian fluid. For grease plasticizers (called non-Newtonian fluids), the corresponding law of internal friction is t0 is the initial shear resistance of the grease.
Grease applicators should sometimes consider the time dependence of fluid flow. The Reynolds equation is the basic equation describing the pressure distribution of a hydrodynamic lubricating film. The conventional Reynolds equation is based on the equation of motion for viscous fluids, also known as the Navier-Stokes equation. It is obtained by combining the mass continuity equation with some assumptions. In general, the surface tension effect is small and negligible. The extrusion effect can also be neglected when the film thickness h is certain.
Therefore, in most cases, the wedging effect of the lubricant of the oiling device is the main factor to generate the oil film pressure. For gas dynamic pressure lubrication, a state equation should be added to the general Reynolds equation. If the lubricating gas is considered as a real gas and satisfies the multiparty relationship, CP and V are constant pressure specific heat capacity and constant specific heat capacity volume.
The isothermal flow is at n=1; the adiabatic flow is at n=1.401 (air). In solving the general Reynolds equation, it is necessary to use the Reynolds equation to solve the equation. Oiling device boundary lubrication when there is a thin film (boundary film) between two friction surfaces lubrication state. This phenomenon usually occurs when the machine is started or stopped.
Aluminum foil oiling can be divided into sheet aluminum foil according to its shape. Most of the raw materials for the deep processing of aluminum foil are supplied in roll form. Only a few manual packaging occasions use aluminum foil. Aluminum foil coating oil can be divided into hard foil and soft foil according to its status. Aluminum foil oiled hard foil: Rolled aluminum foil without softening treatment (annealing) and degreasing treatment has a residual surface.
Aluminum foil coated with oil is a stamping material made of aluminum rolled directly onto a thin sheet. The stamping effect of aluminum foil coated with oil is similar to that of pure silver foil, so it is also called fake silver foil. Due to its softness and ductility, aluminum has a silvery-white luster. Aluminum foil can also be printed if the rolled sheet is mounted on offset paper with sodium silicate and other materials.
Knife beam type electrostatic oiling equipment is oil pump directly on the knife beam, through the tiny gap of the knife beam to spray oil. Because the gap of the knife beam is very small, so the oil purity requirements are very high. In actual production, it is impossible to completely clean the annealed strip or the cleaned strip surface with more or less residual iron powder and dust, which will inevitably cause the knife beam (especially the lower knife beam) to be blocked during the continuous production process, resulting in uneven oiling or leakage on the strip surface. Nozzle type electrostatic oiling equipment uses air pressure to pump oil to the nozzle and then sprays the oil out, so even if there are some tiny impurities in the oil under the pressure of the pump and air, the nozzle will not be clogged. Even if there is slight clogging, the impurities can be blown out of the nozzle by directly increasing the air flow, thus ensuring the quality of oiling.
Today, with the flourishing of science and technology, the help of oiling equipment is indispensable for everything from hot water to security doors, to cars or buildings. It can be said that because of the existence of oiling equipment, it not only saves the time we don't need to waste in our daily life, but also reduces some unnecessary expenses and plays a significant role in the direction of our business. On the contrary, some delays in production or mistakes in details may bring adverse effects to ourselves, so it is still important to grasp this link.
The electrostatic oiling equipment consists of oiling chamber, high voltage electrostatic power supply, oil supply system, oil circuit heating and circulating system, electric control system and operating table. The upper and lower oiling knife beams/nozzles are horizontally installed in the oiling chamber, and the steel plate can pass through freely. The oil supply system quantifies the oil supplied to the oiling knife beam/nozzle to flow evenly from the knife gap of the knife beam and nozzle.
Electrostatic oiling equipment is a device that uses high voltage electrostatic to evenly spray antirust oil or other process media on the surface of the plate and strip. Composition: Electrostatic oiling equipment consists of oiling chamber, high voltage electrostatic power supply, oil supply system, electric control system and operating table.
