Abstract
The utility model relates to an oil delivery pump, in particular to a three-screw oil delivery pump. The three-screw oil delivery pump comprises a driven screw, another driven screw, a driving screw, a pump body, an upper cover and a lower cover and is characterized in that an enclosed cavity is formed by the pump body and the upper cover and the lower cover; a servo motor is arranged at the top of the upper cover; the driving screw is directly connected with the servo motor and is arranged in the cavity; the two sides of the driving screw are respectively meshed with the driven screw and the other driven screw through spiral teeth to form a three-screw transmission device; and the upper and lower ends of the driving screw, the driven screw and the other driven screw are fixed in the cavity through a fixing seat. Compared with the prior art, the three-screw oil delivery pump not only has the advantages of simple structure and high pressure, is suitable for various occasions, but also has the characteristic of long delivery procedure.
Description
Technical field
The utility model relates to a kind of oil transfer pump, a kind of specifically three screw rod oil transfer pumps.
Background technique
Generally be used widely at present, but generally mostly be gear pump at industry oil transfer pumps such as oil, chemical industry, because in the zone that the structural feature of gear pump only is suitable for and the conveying flow process is less, and the flow of the fluid of gear pump can not change by pressure head.
Summary of the invention
The utility model provides a kind of three screw rod oil transfer pumps in order to overcome the deficiencies in the prior art.
To achieve these goals, the utility model has designed a kind of three screw rod oil transfer pumps, comprises driven screw rod, another driven screw rod, and the active screw rod, the pump housing, loam cake, lower cover is characterized in that: the pump housing and loam cake, lower cover are formed the chamber of a sealing; Last tops is provided with actuating motor, initiatively screw rod directly links to each other with actuating motor and places in the chamber, the both sides of active screw rod mesh driven screw rod by thread respectively and another driven screw rod is formed three screw actuators, and initiatively the two ends up and down of screw rod, driven screw rod and another driven screw rod are fixed in the chamber by fixed base.
The bottom of the both sides of the described pump housing and top are formed for import and the outlet that fluid sucks and discharges respectively.
The thread surface of described active screw rod, driven screw rod and another driven screw rod forms oil sucting cavity and oil-discharging cavity, and oil sucting cavity and oil-discharging cavity are same thread surface.
Joint between described active screw rod, driven screw rod, another driven screw rod and the fixed base is provided with and is used to prevent the metallic seal revealed.
The utility model is compared with prior art, and is not only simple in structure, pressure is high, be applicable to various occasions, and has the advantages that to carry long flow path.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1,1 is the pump housing; 2 is loam cake; 3 is lower cover; 4 is chamber; 5 is actuating motor; 6 is the active screw rod; 7 is driven screw rod; 8 is another driven screw rod; 9 is fixed base; 10 are import; 11 are outlet; 12 is oil sucting cavity; 13 is oil-discharging cavity; 14 are metallic seal.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As depicted in figs. 1 and 2, the utility model comprises driven screw rod 7, another driven screw rod 8, active screw rod 6, the pump housing 1, loam cake 2, lower cover 3.The bottom of the both sides of the pump housing 1 and top are formed for import 10 and the outlet 11 that fluid sucks and discharges respectively.The pump housing 1 and loam cake 2, lower cover 3 are formed the chamber 4 of a sealing; Loam cake 2 tops are provided with actuating motor 5, initiatively screw rod 6 directly links to each other with actuating motor 5 and places in the chamber 4, initiatively driven screw rod 7 and another driven screw rod 8 compositions three screw actuators are meshed by thread respectively in the both sides of screw rod 6, initiatively the two ends up and down of screw rod 6, driven screw rod 7 and another driven screw rod 8 are fixed in the chamber 4 by fixed base 9, the sealing surface place of fixed base 9 and every group of screw rod is provided with and is used to prevent the metallic seal 14 revealed, and the thread of every group of screw rod surface forms oil sucting cavity 12 and oil-discharging cavity 13, and oil sucting cavity 12 is same thread surface with oil-discharging cavity 13.
Concrete workflow is as follows: when screw pump is worked, actuating motor 5 drives driven screw rod 7 and another driven screw rod 8 and initiatively screw rod 6 bilateral symmetry engagement, pretend the radial force complete equilibrium that is used on the active screw rod 6, initiatively screw rod 6 does not bear bending load, driven screw rod 7 and another driven screw rod 8 suffered radial forces are supported by the pump housing 1 along its whole length, fluid enters in the chamber 4 by import 10, the work that sucks and discharge by the oil sucting cavity on the thread 12 and 13 pairs of fluid of oil-discharging cavity, thus reach the purpose of oil transportation.
