The utility model not only has the advantages of simple structure, compact structure and easy installation, but also has the advantages of simple adjustment and convenient reparation.
Description
The utility model belongs to F01C class technology, particularly relates to a kind of screw expander that carries out energy adjustment.
In the known recovery, the employed a kind of screw expander of small oil field rock gas, Chinese patent 93221440.1 disclosed " screw expander " for example, though it has overcome that general employing turbo-expander or axial flow decompressor exist can produce surge and can not move and be not easy to keep in repair with liquid when underfed deficiency, be to deal with the gas that causes because of tolerance and variation in pressure and expand not exclusively and the overexpansion problem but still also have deficiency.This is because in real-world operation, is lower than multi-purpose station pipeline pressure when parectasis can cause the outlet pressure of decompressor, produces difficulty of transportation, not exclusively can cause the gas temperature drop to reduce when expanding, thereby cold reduces, and influences the recovery rate of device, also influences the efficient of decompressor simultaneously.
The purpose of this utility model is to overcome the deficiency in the known technology and provides a kind of gas that causes because of tolerance and variation in pressure that can solve to expand not exclusively and the screw expander of overexpansion problem.
The purpose of this utility model is achieved in that
Intermeshing the moon is housed in intermediate of the present utility model, the male rotor top is equipped with guiding valve, be shaped on keyway on the guiding valve, feather key is installed in keyway, in the hole of feather key, be fitted with stop pin by locating stud and screw, after in guiding valve, installing and fixing nut body and spiral cover the adjusting leading screw that its front end has the retaining mother is installed also, on intermediate, install the rear end element that has seal ring by regulating leading screw, on rear end element, be fixed with rear end cover, seal ring is housed on its described rear end cover and sealing cover also is housed by screw, regulate leading screw and pass rear end cover, spacer and bearing are installed on the adjusting leading screw of rear end cover front end, installation shaft pressure cap on the adjusting leading screw of rear end cover rear end, bearing gland is installed in rear end cover by screw, on the follower head of the adjusting leading screw that passes bearing gland, crank and tightening nut are housed, regulate to connect between leading screw and the crank key is housed, end at crank also is equipped with handle, is fixed with to cover in outer cover in it with regulating the rear end of leading screw and crank and handle on rear end cover.
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
See figures.1.and.2, on guiding valve 9, be shaped on keyway 29, feather key 7 is housed in it, above-mentioned guiding valve is installed to intermeshing female rotor 27 in the intermediate of the present utility model 3, on the male rotor 28, then stop pin 5 is inserted in the hole of feather key, in order that preventing guiding valve rotates when regulating, stop pin is with locating stud 6 and screw 4 location and fixing, refill adjusted leading screw 10 after being encased in the guiding valve to set screw nut body 8 and spiral cover 26, the front end of this adjusting leading screw also is equipped with retaining female 25, the rear end element 12 that will have seal ring 11 is contained on the intermediate, regulate leading screw and pass rear end element, rear end cover 13 also is housed on rear end element, seal ring 24 and sealing cover 23 are housed on this rear end cover, its sealing cover and rear end cover install with screw 30.Connect above-mentioned adjusting leading screw and pass rear end cover, spacer 14 and bearing 15 are installed on the adjusting leading screw of rear end cover front end; Installation shaft pressure cap 21 on the adjusting leading screw of rear end cover rear end, bearing gland and rear end cover also install with screw 22.Crank 20 and tightening nut 19 successively are installed on the follower head of the adjusting leading screw that passes bearing gland, between adjusting leading screw and crank, also connect key 16 is housed, end at crank is equipped with handle 18, for preventing that natural gas from leaking outer cover 17 is housed also on rear end cover, the rear end of the adjusting leading screw that will expose, crank, handle etc. cover in it.
Operating principle of the present utility model is: according to real-world operation situation rotatable handles 18, by regulate leading screw 10 make guiding valve 9 can be between the yin, yang rotor move left and right, change the element volume of yin, yang rotor and intermediate 3, also change simultaneously the volume of the air aspiration cavity 2 in the front end body 1, reach the purpose of adjusting.When tolerance or pressure increase, shake handle, guiding valve is moved right, increase air inflow, when tolerance or pressure minimizing, shake handle, guiding valve is moved to the left, reduce air inflow this moment.Guarantee the expansion ratio of intakeport of the present utility model and relief opening, make it in optimum condition work.
Advantage and the good effect that the utlity model has are that it utilizes the move left and right of guiding valve, changes Become the element volume of yin, yang rotor and intermediate, also can move different Operation Conditions simultaneously Attitude is adjusted, and has therefore effectively solved because tolerance and pressure change the gas expansion that causes not exclusively to reach The problem of excessive expansion. In addition, the utility model not only have simple in structure, compact, be easy to the system Make installation, regulate simply and overhaul easily advantage but also have.
