Abstract
The utility model discloses an oil gas pump spiral bushing gap adjusting device in order to overcome the long assembly period, low adjusting accuracy and easy wear defects of the existing oil gas pump in which the engaging gap of a drive and a driven screws is adjusted by an adjusting pad. An adjusting bushing (5) is fixedly arranged between the left spiral bushing (3) and the right spiral bushing (6) of a driven shaft (2). One end surface of the adjusting bushing (5) comes into contact with the end surface of the right spiral bushing (6)/the left spiral bushing (3), and a gap is arranged between the other end surface and the left spiral bushing (3)/ the right spiral bushing (6). An adjusting nut (4) is arranged at the gap end of the adjusting bushing (5) with the spiral bushing, and the outer end surface of the adjusting nut (4) comes into contact with the end surface of the left spiral bushing (3)/ the right spiral bushing (6). The utility model has the benefits of reasonable structure, high adjusting accuracy, convenient assembly and adjusting operation and cost reduction.
Description
Affiliated technical field
The utility model relates to a kind of oil-gas mixed delivery pump of oil and gas development, especially oil-gas mixed delivery pump screw-casing lash adjusting device.
Background technique
Oil-gas mixed delivery pump is the capital equipment that the oil gas mixed solution is carried in the oil field, reaches the purpose of conveying oil gas mixing material and increase hydraulic pressure by the engagement of screw-casing on the driving and driven screw rod in the pump housing.Back lash size between screw-casing has determined the ability to work and the working life of oil-gas mixed delivery pump, when the back lash of driving and driven screw rod is 0.1～0.15mm, oil-gas mixed delivery pump is in the ideal operation state, and excesssive gap or too smallly all can produce bigger influence to the real work performance of mixing defeated pump.Mainly by the size that changes spacer the gap between screw-casing is adjusted at present, be subjected to the restriction of spacer size, make that assembly period is long, it is low to adjust precision, and spacer is easy to wear, causes the gap between the screw-casing to change, operating life is short.
The model utility content
Adjust long, the adjustment precision deficiency low, easy to wear assembly period of the back lash existence of driving and driven screw rod by spacer in order to overcome existing oil-gas mixed delivery pump, the utility model provides a kind of oil-gas mixed delivery pump screw-casing lash adjusting device.
The technological scheme that its technical problem that solves the utility model adopts is: oil-gas mixed delivery pump screw-casing lash adjusting device comprises driving shaft, driven shaft, be installed with left hand screw cover and right-hand screw cover on the driving shaft, be installed with right-hand screw cover and left hand screw cover on the driven shaft, screw-casing on the driving shaft and the screw-casing on the driven shaft are meshing with each other.Between the left hand screw of driven shaft cover and right-hand screw cover, be installed with and adjust cover; Adjust cover one end end face and contact with right-hand screw cover/left hand screw cover end face, gapped between the other end end face and left hand screw cover/right-hand screw cover; Adjust cover and the adjustment nut is installed, adjust the nut exterior edge face and contact with left hand screw cover/right-hand screw cover end face with the gapped end of screw-casing; Adjust between nut exterior edge face and left hand screw cover/right-hand screw cover packing ring is installed.
The beneficial effects of the utility model are that rational in infrastructure, adjustment precision height is convenient to assembling and is adjusted operation, reduces cost.

Among the figure: 1. driving shaft, 2. driven shaft, 3. the left hand screw cover is 4. adjusted nut, 5. adjusts cover, 6. right-hand screw cover, 7. Cock screw, 8. Cock screw, 9. packing ring.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
The utility model oil-gas mixed delivery pump screw-casing lash adjusting device, comprise driving shaft 1, driven shaft 2, be installed with left hand screw cover and right-hand screw cover on the driving shaft 1, be installed with right-hand screw cover 6 and left hand screw cover 3 on the driven shaft 2,2 screw-casing is meshing with each other on screw-casing on the driving shaft 1 and the driven shaft.Between the left hand screw of driven shaft 2 cover 3 and right-hand screw cover 6, be installed with and adjust cover 5; The end face of adjusting cover 5 one ends and right-hand screw overlap 6/ left hand screw and overlap 3 end faces and contact, and it is gapped between overlapping 6 that the other end end face and left hand screw overlap 3/ right-hand screw; Adjust cover 5 and be equipped with the gapped end of screw-casing and adjust nut 4, adjust nut 4 exterior edge faces and left hand screw and overlap 3/ right-hand screw and overlap 6 end faces and contact.
For the ease of adjusting, can also overlap installation packing ring 9 between the 3/ right-hand screw cover 6 in adjustment nut 4 exterior edge faces and left hand screw.
Adjust between cover 5 and the driven shaft 2 key 10 is installed; The Cock screw of radially installing on the adjustment cover 58 will be adjusted cover 5 and fix with driven shaft 2.Adjust nut 4 and adjust between the cover 5 radially Cock screw 7 is installed.
Use the utility model oil-gas mixed delivery pump screw-casing lash adjusting device: at first, with driving shaft 1 location; Then, use to adjust cover 5 and adjust 4 pairs of driven shafts of nut and carry out axially locating, the precession by adjusting nut 4 or screw out the screw-casing of adjusting on the driven shaft and the back lash between the screw-casing on the driving lever, realization is to the location of driven shaft.After the gap adjustment finishes, will adjust nut 4 and adjust cover 5 fixing by Cock screw 7 and Cock screw 8.
