Summary of the invention
The purpose of this utility model, be to provide a kind of can safety, long period, the low-cost water-spray cooling type hydrogen gas helical-lobe compressor of operation continuously.
The purpose of this utility model is to realize like this, a kind of water-spray cooling type hydrogen gas helical-lobe compressor, comprise cylinder block, be installed in the suction end base and the exhausting end base at cylinder block two ends, be characterized in, also comprise being arranged on positive screw rod and the female screw that its two end axles of cylinder block inner chamber is installed in suction end base and exhausting end base, order is installed in the labyrinth seal structure of positive screw rod and female screw two axial ends respectively, cushion gas sealing configuration and unit loading type double mechanical seal structure, be installed in air-breathing distolateral positive screw rod and female screw tail end synchromesh gear and be installed in water spraying mechanism on the cylinder block.
Above-mentioned water-spray cooling type hydrogen gas helical-lobe compressor, wherein, described synchromesh gear is thick, thin toothing, by adjusting the relative position of thick tooth and thin tooth, can adjust the back lash between the negative and positive screw rod, guarantees not contact mutually between the negative and positive screw rod.
Above-mentioned water-spray cooling type hydrogen gas helical-lobe compressor, wherein, described water spraying mechanism comprises a plurality of hydrojet boxes that are arranged on the cylinder body wall and a plurality of nozzles that are communicated with hydrojet box and cylinder inner cavity.
The utility model water-spray cooling type hydrogen gas helical-lobe compressor makes it compared with prior art owing to adopted above technological scheme, has following tangible advantage and characteristics:
1, owing to adopted the compressor of this positive displacement compressor of double-screw compressor as hydrogen, can overcome existing reciprocating type hydrogen gas compressor can not long period the deficiency of operation continuously, provide a kind of can long period the hydrogen gas compressor of operation continuously.
2, owing to adopted the water spray cooling mechanism, can reduce hydrogen is compressed the temperature that is raise on the one hand to spray into the interior cooling water of compression chamber, and Outlet Gas Temperature is controlled at about 70 ℃; On the other hand water spray into can be in screw clearance and the exhaust end face of screw rod form the liquid film face, play seal action, improved the tightness and the interior minimum cylinder volume efficient of compressor, make the single stage compression ratio can reach 10-18.
3, owing to adopted the sealing configuration of Double End integrated mechanical sealing, cushion gas sealing and labyrinth seal three seal combination, improved the sealability and the reliability of sealing system greatly.
4, owing to adopted the synchromesh gear of thick, thin toothing, by adjusting the relative position of thick tooth and thin tooth, can adjust the back lash between the negative and positive screw rod, guarantee always between the negative and positive screw rod to keep certain back lash and do not contact with each other, thereby not need to lubricate when making screw engages.
Description of drawings
By the description of following examples in conjunction with its accompanying drawing, can further understand the purpose of this utility model, concrete feature of the module and advantage, wherein, accompanying drawing is:
Fig. 1 is the structural representation of the utility model water-spray cooling type hydrogen gas helical-lobe compressor.
Embodiment
See also Fig. 1, the utility model water-spray cooling type hydrogen gas helical-lobe compressor comprises cylinder block 1, suction end base 2, exhausting end base 3, positive screw rod 4, female screw 5, labyrinth seal structure 6, cushion gas sealing configuration 7, unit loading type double mechanical seal structure 8, synchromesh gear 9, water spraying mechanism 10.Suction end base 2 and exhausting end base 3 are installed in the two ends of cylinder block 1 respectively.The two ends of sun screw rod 4 and female screw 5 are installed in respectively on suction end base 2 and the exhausting end base 3, and its rotor portion places the inner chamber of cylinder block 1, and positive screw rod 4 leans on an end of exhausting end base 3 to link to each other with dynamic power machine and imports power.Labyrinth seal structure 6, cushion gas sealing configuration 7, unit loading type double mechanical seal structure 8 are installed in the two ends of positive screw rod and female screw respectively outward in proper order from the cylinder inner cavity end face, two synchromesh gears 9 are installed in the top of the positive screw rod 4 and the female screw 5 of suction end respectively, synchromesh gear 9 is thick, thin toothing, by adjusting the relative position of thick tooth and thin tooth, can adjust the back lash between the negative and positive screw rod, guarantee not contact mutually between the negative and positive screw rod.Water spraying mechanism 10 is installed on the cylinder block.Water spraying mechanism 10 comprises a plurality of hydrojet boxes 101 that are arranged on the cylinder body wall and a plurality of nozzles (not shown) that are communicated with hydrojet box and cylinder inner cavity.
The utility model water-spray cooling type hydrogen gas helical-lobe compressor is when work, hydrogen is forced to be drawn in the open screw rod from suction end, synchromesh rotation along with positive screw rod and female screw, hydrogen is pushed to exhaust end equably in the closed chamber of screw rod and cylinder block formation, in the way of advancing of hydrogen, closed chamber is dwindled gradually, and hydrogen is gradually reduced, temperature raises, and density increases.At the same time, water spraying mechanism constantly sprays into cooling water, and cooling water atomizing back and hydrogen mix, and the heat that absorption hydrogen is produced in compression process also is controlled at the temperature of exit gas about 70 ℃.The water smoke that sprays into forms the liquid film face simultaneously in the screw rotor gap and on the exhaust end face of screw rotor, play seal action, has improved the tightness and the interior minimum cylinder volume efficient of compressor.
Be arranged on the synchromesh gear of positive screw rod and female screw suction end owing to adopted thick, thin toothing, by adjusting the relative position of thick tooth and thin tooth, can adjust the back lash between positive screw rod and the female screw, when counter-rotating, do not contact between positive screw rod and the female screw even if guarantee yet, thereby being in operation, the rotor that makes positive screw rod and female screw do not need to lubricate, only need cooling to get final product, also reduced the wearing and tearing of screw rotor simultaneously, the life-span of having improved screw rotor.
Be arranged on three seal combination at positive screw rod and female screw two ends, blocked hydrogen effectively outside body and the leakage of lubricant oil side, tightness and Security are higher, simultaneously, this seal combination can make hydrogen, water definitely separate with lubricant oil, and infiltration each other can not take place.
The utility model water-spray cooling type hydrogen gas helical-lobe compressor is in its lubricating oil system, also adopted airtight lubricating oil tank, be provided with on lubricating oil tank that high-order blow-down pipe leads to outdoor high-altitude and atmosphere communicates, like this, just in case the seal failure of compressor, cause hydrogen leak to lubricating oil system, the hydrogen that is leaked to lubricating oil system can not be trapped in yet and cause danger in the compressor house.
