Description
Technical Field
The invention belongs to the technical field of lubricating devices, and relates to a micro-lubricating device.
Background
The traditional electrostatic atomization device generally comprises an electrostatic generation device, a liquid supply device, a gas-liquid-electricity conveying pipe, a charging device, a nozzle and the like, wherein the traditional electrostatic atomization device is provided with a high-voltage electrode or a high-voltage electrostatic ring at the outlet of the nozzle according to different charging modes, the high-voltage electrode or the high-voltage electrostatic ring has certain potential danger or instability, liquid drops sprayed by the traditional electrostatic atomization device are negatively charged, a workpiece is connected with the anode, and the lubricating oil liquid drops can generate a good adsorption effect on the surface of the workpiece by electrostatic force.
Research shows that with the increase of the spraying distance in the traditional electrostatic atomization process, the droplets are continuously discharged in the movement process, the electrostatic repulsive force between the droplets is reduced, the collision and agglomeration probability is increased, and the large-particle-size distribution and the small-particle-size distribution of the traditional electrostatic atomization are increased.
Studies have also shown that charged droplet particles are affected by a number of factors, and that they may break up without reaching the Rayleigh limit. By accurately measuring the breaking limit of charged liquid drop particles, the foreign schlempton finds that the charged amount of the tiny liquid drops can be broken when the charged amount does not reach the Rayleigh limit, the charged amount is only 70% -80% of the Rayleigh limit, and when the flow of the gas-liquid path is adjusted to enable the gas-liquid ratio to be kept above 0.1, the charged amount of the liquid drop particles in an atomization area between the nozzle and the workpiece can be broken when the charged amount of the liquid drop particles only meets 55% of the Rayleigh limit, namely, when the electric field strength reaches a certain degree, the liquid drops can be broken. After the charged liquid drops in the atomization area of the traditional electrostatic atomization are crushed once, the charged quantity is lost, and the traditional electrostatic atomization drops cannot be crushed once again, so that the charged refining effect of the traditional electrostatic atomization drops is limited.
The charging modes of liquid drops in the traditional electrostatic atomization technology mainly comprise induction charging, contact charging and corona charging. Regarding induction charge and corona charge, as the electrode rings are exposed in the external environment, spark discharge is easy to occur, and when the operation time of the nozzle is too long or the humidity of the operation environment is large, the surface of the electrode ring can be discharged and broken down due to entrainment of condensed water drops, so that the system cannot stably operate; with respect to contact charging, the high voltage negative electrode is exposed to the outside, which presents a hazard to the operator.
Aiming at the problems, the invention designs a novel electrostatic atomization nozzle and a micro-lubrication system with stronger atomization capability, stronger lubrication capability, higher safety and stability by adopting a charge method of mixing ionized air and liquid mist.
