The present invention contrasts prior art and has following advantage:
(1) with twin-screw dry type without oil machine comparison
1, simple in structure, efficiency is high
Only 6 bearings of water lubrication list screw rod oil-free air compressor, two groups of sealings, one-level compression; Twin-screw dry type oilless compressor, 14 bearings, eight groups of sealings, two-stage compression, efficiency is low.
2, long service life:
Water lubrication list screw rod oil-free air compressor main frame Maximum operating temperature is no more than 45 DEG C, and all parts are all worked at normal temperatures, long service life; Twin-screw dry type oil-free air compressor host work temperature is up to more than 200 DEG C, and distortion and pressure are larger, and component are shorter common working life.
3, energy consumption is low, and operation power charge is low.
Taking 55KW as example, by running and comparing, the power consumption per hour of single screw rod oil-free air compressor is than twin-screw dry type oil-free air compressor economize on electricity 8.8KW, and the electricity charge in 1 year can be saved 50,000 yuan of left and right.
3, maintaining expense is low
Water lubrication list screw rod uses consumptive material without oil machine, is mainly water filter filter core, air-filtering core; And twin-screw dry type needs charging-up lubricant oil without oil machine, change oil strainer, Sealing, air leaks clear device filter core, rotor coating etc.
4, nothing is oily, fire savety is good
Water lubrication list screw rod is without oil machine because having not a particle of lubricant oil in main frame, the air providing is pure, is perfectly safe, and whole unit is operated in below 45 DEG C, completely without fire prevention hidden danger; And twin-screw dry type without oil machine operating temperature up to 200 DEG C, must do fire-proof and explosion-proof processing.
(2) with the comparison of piston type without oil machine
1, noise is low
Water lubrication list screw rod oilless compressor noise is lower more than 20 decibels than piston type oilless compressor
2, energy-conserving and environment-protective
Water lubrication list screw rod oilless compressor energy consumption is more energy-conservation more than 15% than piston oilless compressor, the clean water environmentally safe of discharge
3, simple in structure, few easy workout part
Water lubrication list screw rod oilless compressor main frame does not have easily damaged parts substantially, and piston oil-free compressor is as air valve, piston ring, and it is more that piston such as pays at the easily damaged parts.
The present invention contrasts prior art and has following advantage: more energy-conservation more than 15% than piston oilless compressor, reducing noise is more than 20 decibels; It is than the energy-conservation 15-36% of similar twin-screw oilless compressor.The running temperature of dry type twin-screw oilless compressor is higher than 200 DEG C, greatly energy consumption heat energy on.And the running temperature of water lubrication oilless compressor only has 40 DEG C of left and right, due to water lubrication, environment friendly and pollution-free, 100% pure air can be provided, main consumption in service be water, cost is extremely low.
By technique scheme, the lubricated oil-free air compressor of single screw stem water of the present invention is a kind of energy saving environmental protection product, and the aspect of performances such as its reliability, noise, volumetric efficiency have obvious advantage than piston type and double-screw type.Due to without oily zero-emission, non-environmental-pollution, running at normal temperature, environmental protection and energy saving, maintenance cost is low, is the main selection type of air compressor development ultimate aim.
Above-described is only a kind of water lubrication list screw rod oil-free air compressor preferred implementation of the present invention; should be understood that; for the person of ordinary skill of the art; without departing from the concept of the premise of the invention; can also make some distortion and improvement, these all belong to protection scope of the present invention.
