Description of drawings
Fig. 1 is the block diagram of the utility model air compressor.
Embodiment
The utility model air compressor, include the motor 2 and the air-strainer 1 that are connected with air compressor 3 as shown in Figure 1, and air filter 1 is dried paper filter, and filter opening diameter 15 μ m should take off the dust of removing the surface usually in every 500 hours.Air compressor 3 is connected with air-strainer 1 by butterfly valve 11, air compressor 3 is connected two circuits at place and is connected with deaerator 7 with solenoid valve through atmospheric valve 5, the input end of described two circuits is connected on the different port of butterfly valve 11, also is connected with electric control box 6 between atmospheric valve 5 and deaerator 7.Deaerator 7 is connected with pressure chamber 8, and pressure chamber 8 is provided with feather valve 12, and the output port of pressure chamber 8 forms the loop by pressure controller 10 and electric control box 6, and the input end of pressure controller 10 also is connected with timer 9.
The working principle of whole compressor is that atmosphere is by after air-strainer 1 elimination dust, enter air compressor 3 compressions via butterfly valve 11, and mix with lubricant oil, the pressurized air that mixes with oil enters deaerator 7 by one-way valve, again through a plurality of links of centre, in pressure chamber 8, the use system is sent in output at last.
Air compressor 3 is single screw compressor, and is good because of its equilibrium of forces, bearing load is little, and spider piece does not contact under the effect of lubricant oil with screw rod, so it is atomic to wear and tear, the life-span is very long, and air displacement is 30～40m
3In/min scope, the aspects such as its effect and noise level all are better than the similar parameter of other rotary compressors.Simultaneously due to 6 spiral chutes being arranged on screw rod, 2 star gear body assemblies of corresponding configuration, each screw slot is divided into two spaces, up and down, realize separately air-breathing, compression, exhaust process, so screw compressor is equivalent to a double-acting reciprocating type double-pressing machine of six cylinders, screw rod often rotates a circle and produces 12 compression cycle, and exhaust per minute reaches 36000 times.It provides stablizes pulseless pressurized air, has fully demonstrated rationality and advance that single screw compressor structurally has.
That deaerator 7 mainly contains is simplified, runic, olein separate the compositions such as filter core, oil return pipe component.The air-fuel mixture gas of air compressor 3 outputs tangentially enters simplified, flows along the cylinder inwall, under centrifugal action, has to drip to be aggregated on inwall, then returns on fuel-air mixture, and the sedimentation of dripping is arranged.Utilize like this cyclonic separation method and on return separation method the overwhelming majority separated, and be deposited to simplified bottom (being oil pipe).When the gas that contains a small amount of mist of oil further flowed into the separator filter core, filter core carried out last interception and polymerization to the mist of oil of gas, carried out essence and separated, and sank to the filter core bottom under the oil droplet of formation, through return tube and flow regulator pieces, turned back to the air compressor air intake low-pressure section.And be pure high-quality pressurized air by the gas that minimum pressure valve is discharged.
The effect of pressure controller 10 be time segment to the delivery pressure Automatic Detection and Control of pressure chamber 8, motor 2 and air compressor 3 are in shutdown during few or gas point useless with gas point tolerance used, and pressure chamber 8 is not in unloaded state.Motor 2 and air compressor 3 start automatically when useful gas point uses (reaching breakout pressure).When pressure chamber 8 reaches unloading pressure, pressure controller 10 normally-closed contacts are opened, solenoid valve 4 dead electricity, and atmospheric valve 5 is opened emptying, and normal-closed electromagnetic valve is closed.By feather valve 12, that the gas in pressure chamber 8 is emptying to atmosphere, feather valve 12 cuts out voluntarily the effect of piston spring is little, pressure drop before filter core then, and minimum pressure valve is closed.When air compressor 3 was in the unloaded state operation, motor 2 and air compressor 3 were in and stop.Simultaneously, air compressor 3 is by the effect of unloading aperture, and the pressure in deaerator 7 is to maintain 0.5～0.25MPa, guarantees the minimum requirements of oil circulation.By the unloading number of times that reduces pressure chamber and the dead time that increases motor and air compressor, reach and save the electric energy purpose.
When pressure chamber 8 unloading, if when exhaust pressure had dropped to the lower limit load of pressure controller 10 in the delay time that timer 9 is set, pressure controller 10 got an electric shock and resets, and connects the power supply of each solenoid valve, motor 2 and air compressor 3 will again arrive and start running state.Avoided because the hypotony of pressure chamber 8 causes product quality problem and other fault.
Compare with traditional air compressor, test 11:40 to 13:00 at noon is 80 minute period altogether:
Within this period, the conventional air compressor is each loads 7 minutes, and totally 5 times, the load time is 0.75 hour (80-35=45 divides) of 35 minutes (0.58 hour) unloading altogether.Therefore loading 5 times uses electric energy 0.58 * 30kW=17.4 degree altogether, and electric energy 0.75 * 15kW=11.25 degree is used in unloading, and total electricity consumption is 28.65 degree approximately.
16 minutes (0.27 hour) was closed in the each loading of air compressor of the present utility model in 4 minutes totally for 4 times, used electric energy 0.27 * 30kw=8.1 degree, and 1.07 hours * 15kW=16.05 degree during shutdown is saved: the 26.85-8.1=18.75 degree.
26 Working days per month within this period, save per month 26 * 18.75=487.5 degree, annual 12 months, can get thus annual 12 * 487.5=5850 degree electricity of saving, reduced greatly the consumption of the energy, significantly reduced operating cost.
