Abstract
The invention discloses a gas sensor for an oil mist lubrication system, which comprises a light source and a photosensitive element, wherein the light source and the a photosensitive element are arranged on the same side pipe wall of a pipeline, light rays emitted by the light source and the pipe wall form a certain inclined angle, and the light rays pass above the photosensitive element. The range of the inclined angle is set according to the wavelength of the light source and the density of oil mist in the pipeline. The gas sensor for the oil mist lubrication system utilizes the characteristic that the oil mist self is close to a colloid, ingeniously uses the Tyndall effect and allows the light source and the photosensitive element to be arranged on the same side in the pipeline for monitoring the oil mist density, thereby avoiding the phenomenon that oil mist particles are blocked due to over small clearances of the light source and the photosensitive element.
Description
Technical field
The utility model relates to a kind of gas sensor, relates in particular to a kind of gas sensor that is used for the group of pump oil-mist system, belongs to the oil spray lubrication technical field.
Background technology
Oil spray lubrication is a kind of dynamical lubricating system.Its principle of work is such: in oil fog generator, pressurized air mixes with fluid lubricant mutually with the form of torrent, forms small floating mist of oil particles mixture, i.e. mist of oil in airflow.The diameter of these mist of oil particles is generally all at 1～5 micron.By pipe system, mist of oil is transported on the bearing of plant equipment then.Bearing in the continuous lubricating utensil of mist of oil can obtain good and uniform lubricant effect.
Oil-mist system is widely used in a plurality of industries such as petrochemical industry, metallurgy, is applicable to gear, worm gear, slide plate, guide rail and various bearings lubricated of sealing.In the working practice of oil spray lubrication, be a crucial job to the monitoring of oil mist concentration in the pipe system.If oil mist concentration is low excessively, the bearing in the group of pump can not get effectively lubricating; If oil mist concentration is too high, then in pipe system, condense easily, do not have the effective lubricating effect equally.
At present, generally adopt the principle of similar smoke alarm at the monitoring of oil mist concentration in the pipe system.As shown in Figure 1, in this gas concentration detection apparatus, light-emitting component and infrared receiver is opposed or tilting, in the metal housing of packing into, infrared receiver is sensed the power of the infrared ray that is come by light-emitting component direct projection or reflection, produces the signal of expression gas concentration.
But, because the opposed or tilting mode of the general employing of light-emitting component of the prior art and infrared receiver, mist of oil must be by the gap between them, and this gap receives that the influence of light intensity is unsuitable excessive, therefore to the mist of oil particle normally by having caused adverse influence.
Summary of the invention
The purpose of this utility model provides a kind of gas sensor that is used for oil-mist system.This gas sensor can not influence normally passing through of mist of oil particle.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of gas sensor that is used for oil-mist system comprises:
Be arranged on light source and light activated element on the tube wall of pipeline the same side.
The light that described light source penetrates and the tube wall of described pipeline form certain included angle, and described light is through directly over the described light activated element.
The scope of described angle is set according to the wavelength of light source and the oil mist concentration in the pipeline.
Described light source is infrared light supply or far infrared light source.
Oil-mist system gas sensor described in the utility model utilizes mist of oil itself to approach the characteristic of colloid, creatively utilize Tyndall effect, the monitoring of oil mist concentration is carried out in the same side that light source and light activated element are placed in the pipeline, avoided light source and light activated element gap too small the obstruction of mist of oil particle by causing.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a kind of structural representation of typical gas concentration detection apparatus;
Fig. 2 is the structural representation of oil-mist system gas sensor provided by the utility model.
Embodiment
This oil-mist system gas sensor comprises the light source 1 and the light activated element 2 that are arranged in the gas pipeline 10 as shown in Figure 2.Light source 1 and light activated element 2 are arranged on the same side of pipeline 10.In Fig. 2, both all are positioned at the following tube wall of pipeline 10.Certainly, the both to be positioned at the upper tube wall of pipeline 10 also be feasible.
The light 3 that light source 1 penetrates forms angle with the tube wall of pipeline 10, and the preferable range of this angle is set according to the wavelength of light source 1 and the oil mist concentration in the pipeline 10.In practical operation, according to the Tyndall effect of hereinafter introducing, under the suitable situation of oil mist concentration, light 3 is directly scattering not, but forms a light beam that passes through light activated element 2 tops.For light activated element 2, this light beam is equivalent to the effect that " virtual light source " that is positioned at directly over the light activated element is shone.Oil mist concentration is big more, and the light intensity of being somebody's turn to do " virtual light source " is also big more, so the electric current of inducting on the light activated element 2 is also big more.The characteristic that size of current on this light activated element 2 changes in the same way along with oil mist concentration can be used for realizing the monitoring to oil mist concentration in the pipeline.
Above-mentioned light source 1 and light activated element 2 utilize the concentration of Tyndall effect detected gas.So-called Tyndall effect is such: in the communication process of light, when irradiate light arrives particle, if particle is doubly a lot of greater than lambda1-wavelength, reflection of light takes place then; If scattering of light less than lambda1-wavelength, then takes place in particle, at this moment observed be light wave around particulate to its panodic light, be called scattered light or opalescence.Tyndall effect is exactly scattering of light phenomenon or opalescence phenomenon.
In the utility model, when the oil mist concentration in the pipeline 10 was very low, the light 3 that penetrates from light source 1 entered the mist of oil in the pipeline 10, and Tyndall effect can not take place this moment.The light 3 that light activated element 2 is sensed is more weak, and the electric current of generation is less, and the concentration of expression mist of oil is very low.When oil mist concentration was in usable range, the light activated element 2 in the pipeline 10 was under the identical situation of light source, and along with the increase of oil mist concentration, the light intensity that receives also can correspondingly increase, thereby the electric current that produces also can increase.
Because the particle of mist of oil is bigger, in order to obtain good monitoring effect, light source 1 is preferably infrared light supply or far infrared light source, but also can be the light source of other wavelength.
Above this oil-mist system gas sensor is had been described in detail.For one of ordinary skill in the art, any conspicuous change of under the prerequisite that does not deviate from the utility model connotation it being done all will constitute to the utility model infringement of patent right, with corresponding legal responsibilities.
