Abstract
The present invention relates to a kind of plateau DC frequency-changing oil-free gas compressor, including：Motor, bent axle, connecting rod, piston, air valve, sealing ring, DC frequency-changing module；Device energy conservation environmental protection, overlong service life, oil-free is wear-resistant, can adapt to the various environment such as plateau.
Description
Technical field
The present invention relates to a kind of bleed pressure supply oxygen manufacture field, and in particular to a kind of plateau DC frequency-changing oil-free gas compressor.
Background technology
Currently, there are various Domestic oxygen erators on the market, because the principle of oxygen processed is different, the handling characteristics of each Domestic oxygen erator are also just different.Domestic oxygen erator oxygen principle has：1st, molecular sieve principle；2nd, Polymeric Oxygen Enrichment Membranes principle；3rd, electrolysis water principle；4th, chemically react oxygen principle processed.And molecular-sieve oxygen generator is currently the only ripe, the oxygenerator with international standard and national standard.
Molecular-sieve oxygen generator, by physical principle, with huge discharge oilless (oil free) compressor as power, separates the nitrogen in air with oxygen using the absorption property of molecular sieve, finally gives the oxygen of high concentration.Such oxygenerator produces oxygen rapidly, and oxygen concentration is high, it is adaptable to which various crowd's oxygen therapies and oxygen health care, power consumption are low, low cost.
Become particularly important as the effect of the oilless (oil free) compressor of molecular-sieve oxygen generator power source, it is current domestic it is general be have oil lubrication without oil machine, so in compression process more or less, oil can be contained in air, there is greatly adverse effect to molecular sieve adsorption, and resin material lubrication is used, being lost in because the lubricating grease for sealing is easy causes bearing to be dry grinded and damages, and quality is nor very satisfactory.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of plateau DC frequency-changing oil-free gas compressor, and the device energy conservation is environmentally friendly, and overlong service life, oil-free is wear-resistant, can adapt to the various environment such as plateau.
In order to solve the above-mentioned technical problem, a kind of plateau DC frequency-changing oil-free gas compressor that the present invention is provided, including：Motor, bent axle, connecting rod, piston, air valve, sealing ring, DC frequency-changing module；The motor, is the power source of the present apparatus, converts electrical energy into kinetic energy, produces driving torque, drives bent axle to be operated；Bent axle is whole power that the present apparatus transmits compressor, and its Main Function is the linear reciprocating motion that the rotary motion of motor is changed into piston by connecting rod.Bent axle bears the alternation composite load for drawing, press, shear, bending and reversing in motion, and condition of work is severe, therefore the present apparatus is cast using spheroidal graphite cast-iron QT50-1.5；The connecting rod is the connector of bent axle and piston space, the gyration of bent axle is converted into the reciprocating motion of piston for it, and power is passed to piston to gas acting, is easily born to draw due to connecting rod, is pressed alternate load, therefore typically cast with spheroidal graphite cast-iron QT40-10, I-shaped cross-section is used shaft more；The piston does reciprocating linear motion under connecting rod drive in cylinder, and so as to collectively constitute a variable swept volume with cylinder etc., to realize the processes such as air-breathing, compression, exhaust, because piston is easy to wear, therefore the present apparatus is using solid lubrication anti-abrasive material；The steam valve includes inlet valve and air bleeding valve, and piston often pumps once, and suction, air bleeding valve are respectively opened and closed once, so as to control compressor and it is completed four courses of work such as air-breathing, compression, exhaust；The sealing ring prevents refrigerant vapour from being leaked out along bent axle external part, or when crankcase pressure subatmospheric, prevent outside air from leaking into, so good sealing and security reliability should be had, present apparatus sealing ring uses solid lubrication anti-abrasive material, and solid lubrication is made with native graphite, the problems such as solving lubricating oil and be mixed into air, and working life is extended, job costs are reduced；The fixed mains frequency of 50Hz is changed to 30-130 by the DC frequency-changing module by realizing automatically adjusting for motor rotation velocity of variation to the conversion of frequency of supply
The change frequency of Hz.Meanwhile, supply voltage accommodation is reached 142-270V, solve the problems, such as that influence equipment works due to the unstable of line voltage.
The present invention has the advantages that：
The present invention is simple and reasonable, and simple operation, noise is low, low in energy consumption, energy-conserving and environment-protective, and overlong service life is wear-resistant, is suitable for the adverse circumstances such as plateau, high temperature, high humidity, high and cold.
Specific embodiment：
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is schematic diagram of the invention.
After electric motor starting, motor single-shaft drives compressor crank shaft rotation, by the transmission of connecting rod, the piston with self-lubricating without any lubricant just moves reciprocatingly, and the swept volume being made up of cylinder inner wall, cylinder head and piston-top surface then can generating period change.From at cylinder head during setting in motion, the swept volume in cylinder gradually increases the piston of piston compressor, and at this moment, gas is, along air inlet pipe, to push intake valve open and enter cylinder, and untill when swept volume changes to maximum, intake valve is closed；When the piston reverses direction of piston compressor is moved, swept volume is reduced in cylinder, and gas pressure is raised, and when inner pressure of air cylinder reaches and is slightly above pressure at expulsion, air bleeding valve is opened, gas discharge cylinder, until piston movement is to extreme position, exhaust valve closure.When the piston counter motion again of piston compressor, said process repeats.I.e.：The bent axle of piston compressor rotates a circle, and piston reciprocating once, realizes air inlet, compression, exhaust in succession in cylinder.
