Embodiment
Below in conjunction with drawings and Examples, the adjustable oil fog generating apparatus of a kind of precision of the present utility model is further described.
As shown in Figure 1, the oil fog generating apparatus specific works process that a kind of precision of the present utility model is adjustable is as follows: pressurized air (dry air after filtration, heating and voltage stabilizing) enters after the separate space of generating means body 19 and Venturi tube 12 by suction port 14, inlet hole along nozzle 20 enters nozzle chamber, and enters spray chamber 10.Due to the Venturi effect that high velocity air produces, the interior generation negative pressure of vacuum chamber 1, the lubricant oil in fuel tank 22 is removed impurity through oil purifier 8, then enters vacuum chamber 1 through oil pipe suction inlet 9, oil dripping tube 3.Oil droplet splashes into Venturi tube 12 top positions, and lubricant oil, through the center hole of Venturi tube 12, flows at a slow speed spray chamber 10.In spray chamber, oil droplet is ground into countless trickle elaioleucites by high velocity air, becomes ultra micro mist of oil.In these mist of oil particles, the larger elaioleucite of small part particle diameter, under self gravitation effect, falls back to fuel tank 22, and particle diameter is little, from the elaioleucite of heavy and light from mist of oil outlet 17 outputs, and be transported to each lubricating point.
The adjustable oil fog generating apparatus of a kind of precision of the present utility model has following features:
(1) oil pipe suction inlet 9, can pass through adjusting bolt 4, regulate oil inlet quantity, can make oil mass be accurate to Yi Diwei unit.The end of adjusting bolt 4 is designed to taper mouth, is inserted in oil pipe suction inlet, by rotation adjusting bolt, can control the degree of depth that bolt inserts oil pipe suction inlet, thereby realizes the precise fine-adjustment to oil inlet quantity.In adjusting bolt 4, be designed with dual O type circle 7, for realizing the sealing with device body 19 inwalls, prevent the leakage of lubricant oil in adjustment process;
(2) in order to confirm the number of lubricant oil oil inlet quantity, at generator top, visual clear glass window 2 is installed, can observes herein the oil dripping amount of oil dripping tube 3.And regulate lubricant oil oil inlet quantity according to actual conditions; Clear glass window 2 is fixed and is sealed by fixing bolt 6 and seal ring 13;
(3) Venturi tube is designed with a plurality of equally distributed nozzles of air supply 20, Venturi tube center is with oil dripping hole 16, for improving the atomizing effect of oil droplet, the bottom design of oil dripping hole 16 is become to expand bore, the oil droplet flowing down along oil dripping hole inside is through expanding after bore, by the pressurized air of high velocity jet, be ground into trickle elaioleucite, become ultra micro mist of oil, the particle diameter of most oil droplets is all below 2 μ m;
(4) consider that mist of oil is all to produce at spray chamber 10, be that the place that carbonization is gathered the most easily occurs herein.Therefore,, by Venturi nozzle 20 outlet upper areas, be designed to circular-arc chamfering 18.This be due to, the relative acute angle chamfering of circular arc chamfering, can effectively hinder the generation that carbonization is gathered, and reduces the blocking probability of oil fog generating apparatus;
Obstruction and the maintenance clean of considering Venturi tube 12, Venturi tube top design has dismounting tapped hole 11, during dismounting, as long as screw is screwed into tapped hole, upwards once drawing, Venturi tube can be extracted, very convenient; Venturi tube 12 seals with device body by upper seal ring 15 and lower seal 21 up and down.
The adjustable oil fog generating apparatus of a kind of precision of the present utility model; can guarantee that oil-feed is adjustable and fuel feeding is normal, reduce generator blocking probability, and can produce the ultra-fine mist of oil below particle diameter 2 μ m; guarantee that each end lubricating point is used normal, reduce Stop-Time of Device Failure.
