Abstract
The utility model relates to an oil pump, which is mainly used in slip sheet type oil transfer pump for conveying liquid medium in petroleum industry, chemical industry and brewing industry, and can also be used in mixed conveying of fluid medium such as oil, water and steam flow. The utility model comprises a pump body, wherein, the main shaft arranged inside the pump body is provided with a rotor; the circumference of the rotor is provided with radiate slide sheets; the inside of the pump body is provided with a set of rotor axis-rotor device which is symmetrical to the main shaft and is arranged at intervals relative to the main shaft; moreover, the main shaft is connected with the rotor axis through gear drive; the discharge port and the pumping port are arranged at the same level; in addition, the rear end of each slip sheet is provided with a spring. The utility model is characterized by low noise, smooth operation, high efficiency and big conveying capacity.
Description
Technical field
The utility model relates to a kind of oil pump, is mainly used in the vane fuel supply pump of oil, chemical industry, the conveying of brewing industry liquid medium, and the mixing that also can be used for oil, water, steam flow body medium is carried.
Background technique
In prior art, oil transfer pump comprises the rotor on the pump housing, the pump housing inner main axis, the stator in the pump housing, and its shortcoming is to have only a cover rotor arrangement in the pump housing, and pump delivery is lower, does not reach designing requirement.The row of the pump housing, suction inlet become an angle of 90 degrees design arrangement, make that dirt accumulates in the pump chamber easily in the medium of conveying, and resistance increases, and influences the flow velocity and the efficient of pump.It is flexible that slide plate (blade) only depends on centrifugal action to realize, turnover is affected, and contacts imprecision with stator, influences the efficient of pump.
The model utility content
The purpose of this utility model is to provide the oil transfer pump that a kind of discharge capacity is big, efficient is high at above-mentioned deficiency.
Technical solution of the present utility model is: oil transfer pump comprises the pump housing, on the pump housing inner main axis rotor is arranged, and rotor upper edge circumference is equipped with slide plate radially.In the pump housing with main shaft at interval, row is provided with a cover rotating shaft rotor arrangement, be connected by gear transmission between main shaft and the rotating shaft.The row of the pump housing, suction inlet are on same horizontal line.Each slide plate rear portion is provided with spring.Oil-return groove is located on the pump housing outer wall, is connected with suction port.
The utility model has the advantages that: 1, have the rotation of the cover of two on two axles of two gear drivens movement rotor, discharge capacity is big, can satisfy usage requirement.2, the design of row's suction inlet of pump makes the dirt in the fed sheet of a media be difficult for accumulating in the pump chamber on a horizontal line, and clear and coherent smooth, the non-resistance of the MEDIA FLOW of conveying does not reduce flow velocity.3, the slide plate rear portion has installed dual spring additional, make under slide plate acts in centrifugal force and dual spring, straight fore and aft motion tightly contacts stator inner wall, do not clash into the side plate plane, do not produce vibration, do not damage the smoothness of side plate, reduced machine members, prolonged the life cycle of equipment, simultaneously, do not leak, suction capacity is strong.4, changed the position (casting is on the outer wall of the pump housing) of oil-return groove, the oil of returning sucks pump chamber simultaneously by suction port, has alleviated the damage of blade and side plate.5, it is little to have a noise, operates steadily efficient height, the characteristics that quantity delivered is big.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model structure diagram;
Fig. 2 is the pump body structure sketch.
Embodiment
Referring to Fig. 1, on the oil transfer pump pump housing 1 inner main axis 2 rotor 3 is arranged, rotor 3 upper edge circumference are equipped with slide plate 4 radially.In the pump housing 1 with main shaft 2 at interval, row establishes, symmetry has another set of rotating shaft rotor arrangement, i.e. be connected by two gear 6 Synchronous Transmission between the rotating shaft 5, main shaft 2 and rotating shaft 5.This structure Design has guaranteed the big discharge capacity of pump.
Referring to Fig. 2, the row of the pump housing 1, suction inlet 7,8 are on same horizontal line.Each slide plate 4 rear portion is provided with spring, can be two springs side by side.(figure slightly).Oil-return groove 9 is located on the pump housing 1 outer wall, is connected with suction port 8.
