Abstract
The invention discloses a lubricating oil system of an air compressor. The lubricating oil system comprises a heat exchanger, a temperature-sensing valve, a filter and the air compressor, wherein a pressure maintaining valve is arranged between the filter and the air compressor. The lubricating oil system of the air compressor provided by the invention has the advantages that the structure is simple, the less cost needs to be added, the load characteristic of the compressor is greatly optimized, and noises are lowered.
Description
Technical field
The present invention relates to a kind of air compressor device, particularly relate to a kind of air-compressor lubricating oil system.
Background technique
Along with industrial expansion, compressor is used to increasing.Air compressor is as a kind of universal machine, and is more extensive in China's commercial Application.Air compressor is used for general power gas source, and it is widely used in the industries such as machinery, medical treatment, weaving, food, electric power, automobile, iron and steel, oil, chemical industry, railway, building materials and military project, and one of helical-lobe compressor main device that to be this source of the gas provide.
In fuel injection helical lobe compressor, need in the screw host active chamber, spray into the lubricant oil with certain pressure, the oil that sprays into directly contacts with pressurized gas, absorb on the one hand the heat of compression of gas, spraying into of oil makes the characteristic of helical-lobe compressor that great changes occur on the other hand, improved adaptable pressure and pressure ratio, and design simplifies the structure, and make delivery temperature obtain effective control, also reduced noise.The oil that sprays in the compressor mainly contains cooling, sealing, lubricated and four functions of noise reduction.As shown in Figure 1, in the injection system of fuel injection helical lobe compressor, lubricant oil enters oil strainer 30 from cooler 10 through thermostat valve 20 under the effect of exhaust pressure, sprays into compressor 40 by oil pipe line again and participates in compression; Because the size of injection pressure depends on the variation of exhaust pressure fully, and a stable injection pressure can not be provided, and causes the increase of the power consumption of compressor.
Oil spout in the Normal squeezing machine is to realize by the pressure difference that forms between complete machine exhaust pressure and the jet; In actual use, owing to being subjected to the fluctuation of the performance impact of each accessory of oil-way system and user's actual working pressure, add the liquid of lubricant oil own and have compressibility, these factors often cause the unstable of compressor jet injection pressure, cause the operation of compressor complete machine the phenomenon that noise is unusual, power consumption increases can occur.Those skilled in the art is devoted to relate to a kind of novel lubricating oil system.
Summary of the invention
The technical problem to be solved in the present invention is in order to overcome in the prior art, and the lubricating oil system of air compressor sprays into the unsettled deficiency of lubricating oil pressure, provide a kind of can be to the stable system that sprays into lubricant oil of compressor.
The present invention solves above-mentioned technical problem by following technical proposals:
A kind of air-compressor lubricating oil system comprises heat exchanger, thermostat valve, filter and air compressor, and its characteristics are, a pressure maintaining valve is set between described filter and the air compressor.
Preferably, described pressure maintaining valve is the piston type pressure maintaining valve.
Preferably, described pressure maintaining valve is the diaphragm type pressure maintaining valve.
Preferably, described pressure maintaining valve is near the air compressor setting.
Preferably, described air compressor is helical-lobe compressor.
Among the present invention, but above-mentioned optimum condition combination in any on the basis that meets related domain general knowledge namely gets each preferred embodiment of the present invention.
Positive progressive effect of the present invention is: this air compressor lubrication system architecture is simple, does not need to increase too many cost, greatly optimizes the load characteristic of compressor, has reduced noise.
Description of drawings
Fig. 1 is the structural representation of compressor lubrication oil system in the prior art.
The structural representation of the air-compressor lubricating oil system under specific embodiment of Fig. 2 the present invention.
Embodiment
Embodiments of the invention describe with reference to the accompanying drawings.In Figure of description, the element with similar structure or function will represent with identical component symbol.Accompanying drawing is each embodiment of the present invention for convenience of explanation just, is not to carry out to the present invention the explanation of exhaustive, neither limit scope of the present invention.
Fig. 2 illustrates the structural representation of the air-compressor lubricating oil system under specific embodiment of the present invention.In this embodiment, lubricant oil enters filter 30 through after the heat exchange in cooler 10,20 pairs of oil temperatures of thermostat valve are monitored therebetween, and lubricant oil sprays into compressor 40 through pressure maintaining valve 50, gets back to cooler 10 via other pipeline (scheming not shown) subsequently and carries out heat exchange.
It will be appreciated by those skilled in the art that, pressure maintaining valve 50 is the comparatively ripe product of industry, can be diaphragm type, spring diaphragm type, piston type, Lever type or bellow type, can be all applicable to the valve that the jet pressure of lubricant oil is effectively regulated as long as be fit to.
Because the liquid compressibility of lubricant oil is larger, so lubricant oil mobile often build-up of pressure unsteady phenomena in long pipeline, therefore in a preferred embodiment, pressure maintaining valve 50 should arrange near compressor 40, like this, lubricant oil enters compressor as early as possible through behind the pressure maintaining valve, has avoided elastic liquid to enter the defective that the front jet pressure of air compressor changes.
The technician can calculate the switching pressure threshold value of pressure maintaining valve in the following manner:
1. according to power and the heat exchange amount of compressor, calculate best fuel injection quantity;

2. according to the diameter of oil pipe line, calculate best injection pressure according to best fuel injection quantity;
3. according to result of calculation, set the steady pressure of voltage stabilizing control valve, realize the stable of injection pressure.
Those skilled in the art will appreciate that this technology can not only be applied on the screw air compressor device, other needs the power plant of the lubricant oil of jetting stability all can use the technical program.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited by appended claims.Those skilled in the art can make various changes or modifications to these mode of executions under the prerequisite that does not deviate from principle of the present invention and essence, but these changes and modification all fall into protection scope of the present invention.
