Embodiment
Describe the embodiment of the utility model below in detail, said embodiment's example is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Be exemplary through the embodiment who is described with reference to the drawings below, only be used to explain the utility model, and can not be interpreted as restriction the utility model.
In the description of the utility model; The orientation of indication such as term " top ", " bottom " " top ", " below " or position relation are for concerning based on orientation shown in the drawings or position; Only be for the ease of describing the utility model rather than requiring the utility model therefore can not be interpreted as restriction with specific azimuth configuration and operation to the utility model.
The compression system of the utility model embodiment's rock gas is described with reference to figure 1 below.
As shown in Figure 1, the compression system structural representation of the natural gas that provides for the utility model embodiment comprises the cylinder with suction port 11 and air outlet 12, and is positioned at the wherein piston 2 of cylinder 1, it is characterized in that, also comprises:
Hold the fuel reserve tank 31 of lubricant oil, be arranged on outside the cylinder 1;
At least one oil nozzle 33 and oil pump 32; Oil nozzle 33 is arranged in the groove on cylinder 1 inwall; The inlet port of oil pump 32 connects the oil outlet of fuel reserve tank 31, and oil outlet connects each oil nozzle 33 through pipeline road, and with certain pressure in piston 2 backhauls; Overcome the pressure of gas in the cylinder 1, the lubricant oil in the fuel reserve tank 31 is ejected on cylinder 1 inwall through oil nozzle 33.
Because the lubricant oil in oil nozzle 33 is flowing liquid; When the outside exhaust of cylinder 1, can receive the effect of cylinder 1 internal air pressure and reflux, therefore; Still, can on the pipeline road that connects oil nozzle 33, install the one-way valve 34 that is used to prevent the lubricant oil backflow additional referring to shown in Figure 1.
Wherein, one-way valve 34 can be arranged on the pipeline road, can allow lubricant oil to get into oil nozzle 33; But can not reflux; The benefit of this kind design is, can stop the lubricant oil of not ejection to be got back to once more in the fuel reserve tank 31, also can stop gas to get into fuel reserve tank 31 along pipeline road simultaneously.Certainly, as shown in Figure 7, one-way valve 341 also can be provided with in the oil nozzle 33, passes back into pipeline road to stop lubricant oil and gas.Perhaps in pipeline road and oil nozzle 33, all install one-way valve additional.
As shown in Figure 2, a kind of oil nozzle 33 distributed architecture schematic representation of the utility model embodiment, oil nozzle 33 can have a plurality of, for example two or more oil nozzles 33, at this moment, a plurality of oil nozzles 33 are evenly distributed on cylinder 1 inwall.
Concrete; The mode of the arrangement of two or more oil nozzles 33 can be laterally to arrange along cylinder 1 inner peripheral wall; Also can be vertically to arrange along piston 2 travel directions; Purpose is a plurality of oil nozzles 33 that on cylinder 1 inwall, distribute, and makes piston 2 can more touch the lubricant oil that is sprayed on cylinder 1 inwall.
As shown in Figure 4, for piston 2 peripheries can comprehensively contact the lubricant oil that is sprayed onto on cylinder 1 inwall, a plurality of of the utility model embodiment are distributed as at least one circle at oil nozzle 33 along cylinder 1 inner peripheral wall is equally spaced.
At this moment, a plurality of oil nozzles 33 can distribute a week in the peripheral equal intervals of cylinder 1 inwall, and when piston 2 ran to cylinder 1 inner wall section of being sprayed lubricant oil, the whole periphery of piston 2 can touch lubricant oil, the high lubricating effect that therefore plays.As shown in Figure 3, when oil nozzle 33 was distributed as two circles or the above structure of two circles, the spacing of the oil nozzle between each circle can equate that also in this kind design, the lubricant oil spray area on cylinder 1 inwall is bigger, and lubrication effect is better.
Like Fig. 8, shown in Figure 9; Oil nozzle 33 is mounted in the absolute construction in cylinder 1 inboard wall groove; Concrete oil nozzle 33 structures comprise two-part again: the pipe shape jetburner 331 and the pipe shape oil pipe 332 of connection; Belong on the plane at pipe shape jetburner 331 and pipe shape oil pipe 332 axis; Angle between the outer wall of tube-shaped sputtering mouth 331 and tubulose oil pipe 332 (333) is:
wherein L is angle, and n is a nozzle quantity.
Wherein, the axis of oil pipe 332 is on cylinder 1 inwall radius of a circle along the line, and this kind design can realize that each oil nozzle 33 can cover a circumferential scope of cylinder 1 inwall basically, makes piston 2 can play omnibearing lubrication effect through out-of-date.
Certainly, the also slightly angle skew along the line of the axis of oil pipe 332 and cylinder 1 inwall radius of a circle can as the case may be and specifically be set under the prerequisite that can realize lubricated purpose.
The quantity that oil nozzle 33 is distributed on the circumferential same circle of cylinder 1 inwall is different; The spray angle of jetburner 331 is also different with the angle 333 of oil pipe 332 outer walls; Oil nozzle 33 quantity that distribute are many more, and angle 333 is more little, so the injection coverage area of oil nozzle 33 is also just more little.Can realize the purpose of injection with littler oil pressure, reduce the power consumption of oil pump 32.Below describe to oil nozzle 33 quantity of two kinds of preferred versions.
As shown in Figure 5; The arrangement mode of a kind of oil nozzle 33 of the utility model embodiment; Can be that a circle is along equidistant five oil nozzles 33 that distribute of cylinder 1 inner peripheral wall; The axis of the oil pipe 332 of each oil nozzle 33 is on cylinder 1 inwall radius of a circle along the line, and each jetburner 331 sprays to cylinder 1 inner peripheral wall, and the outer wall angle 333 of the outer wall of jetburner 331 and oil pipe 332 is 126 °.
As shown in Figure 6; Also can be: a circle be along equidistant six oil nozzles 33 that distribute of cylinder 1 inner peripheral wall; The axis of the oil pipe 332 of each oil nozzle 33 is on cylinder 1 inwall radius of a circle along the line; Each jetburner 331 sprays to cylinder 1 inner peripheral wall, and the angle 333 of the outer wall of the outer wall of jetburner 331 and oil pipe 332 is 120 °.
The design of following mode further, can also be arranged the jetburner 331 of oil nozzle 33: each oil nozzle 33 can only comprise along cylinder 1 inner peripheral wall folk prescription to a jetburner 331 that sprays; In addition, as shown in Figure 7, can also be the jetburner that each oil nozzle 33 comprises two opposing settings, and 1 inner peripheral wall be sprayed to both sides from oil nozzle 33 along cylinder.The benefit of this kind design is that each oil nozzle 33 two-way injection has increased the area coverage to cylinder 1 inwall, can reduce the number that is provided with of oil nozzle 33 accordingly, and can well realize lubricating piston 2 equally.
In order to guarantee that further the gas makings of discharging in the cylinder 1 is pure, as shown in Figure 1, also comprise: be connected the deaerator 13 outside the said air outlet 12.Through to discharging the further cleaning of gas in the cylinder 1, can filter out a small amount of oil that exists in the gas, better improve the makings quality.
The compressor lubrication device that the utility model provides has changed the omnidistance pattern of spraying of piston in the past, has reduced fuel consumption; Also reduced simultaneously the gas oil content in the cylinder; Effectively play lubrication, also reduced wearing for piston simultaneously, increased working life.
Although illustrated and described the embodiment of the utility model; Those having ordinary skill in the art will appreciate that: under the situation of principle that does not break away from the utility model and aim; Can carry out multiple variation, modification, replacement and modification to these embodiments, the scope of the utility model is limited claim and equivalent thereof.
