Abstract
The utility model relates to a conical screw pump which is a more perfect oil pump designed against the defects of various screw pumps in oil extraction. In order to improve the spiral lifting force, a positive helical groove is arranged outside a rotor and a negative helical groove is arranged in a stator. In order to adjust a gap conveniently, the rotor adopts a conical structure which is matched with an inner conical cavity of the stator. Simultaneously, a plurality of pumps are connected in series to adapt different requirements. Consequently, the purposes of the utility model can be realized. The utility model has the advantages of simple structure, wide application and long service life. The utility model not only reduces the manufacturing cost, but also reduces the operation cost. The development of the utility model can gain better economic benefit.
Description
The utility model belongs to the design and manufacturing technology field of pump.
The existing single, double screw pump that is used for petroleum production all has shortcoming separately: helical rotor pump, its spindle need to make of vulcanite, complex process, cost height, and material can not guarantee forever wear-resistingly, working life is short; Though two screw pump is made more easily of rigid metal and made, be only limited to the lower oil well of sand content and use.And after the wearing and tearing,, the gap scraps, if the reparation cost is higher because of increasing.
A kind of purpose of tapered screw pump is: at the shortcoming of above-mentioned each screw pump, provide a kind of new structure letter, use screw pump wide, that cost is low, the life-span is long.
The utility model realization above-mentioned purpose is taked following technological scheme: as shown in Figure 1: transmission shaft (1) connects the tapered rotor (3) that has the right-handed screw groove by driving key (2) in the pump housing, rotor (3) cooperates with the spindle that has reverse inner spiral groove (4), there are levelling nut (6) and fastening nut (7) in the rotor lower end, descend the series connection pump housing (8) again, the pump housing (8) lower end has oil-in (9), and pump housing upper end has oil export (5).
The utility model has following advantage: 1, each parts of the pump housing are the metal rigid body, and are simple in structure, be convenient to make; 2, have positive and negative spiral chute in outer, the spindle of rotor.Therefore, helical surface is synthesized bigger spiral lift in relatively rotating; 3, the helical surface turning radius from the bottom up, from large to small.Therefore, pressure changes from small to big; 4, according to the needs of different pressures output, can connect by a plurality of pump housings, therefore, improved application area; 5, the matching gap of rotor and spindle is convenient to adjust.Therefore, long service life.
Fig. 1 is a structure diagram of the present utility model.
(1) transmission shaft (2) driving key (3) rotor (4) spindle (5) oil export (6) is adjusted nut (7) fastening nut (8) the series connection pump housing (9) oil-in.
Working principle of the present utility model and process description are as follows:
Oil enters in the spiral chute of pump housing internal rotor (3) and spindle (4) through inlet (9).Transmission shaft (1) connects by driving key (2) gives rotor (3) with transmission of torque, rotor (3) with the relatively rotating of spindle (4) in spiral chute push oil to top with synthetic spiral lift, along the outlet outflow.Thereby finish the technological process of the lifting of oil.For adapting to different operating modes or rotor, the increase of spindle matching gap, can rotate adjustment nut (7) and adjust.Then, with fastening nut (8) locking, thus the normal operation of assurance pump.
According to above-mentioned the 4th, the 7th part explanation, can finish manufacturing, assembling, the debugging of component, implement requirement of the present utility model.
Claims (1)
- A kind of tapered screw pump, its structure comprise the tapered rotor that has the right-handed screw groove, have the spindle of reverse inner spiral groove and adjust nut.It is characterized in that adjust the nut top and join with tapered rotor, tapered rotor outer surface cooperates with spindle inner cone mold cavity surface.
