Abstract
The utility model relates to an oil-gas recovery pump which has high working efficiency and prolongs the service life of a piston. The utility model has the technical scheme that the oil-gas recovery pump is provided with a cylinder sleeve, wherein a piston which can move up and down along the inner wall of the cylinder sleeve is arranged in the cylinder sleeve, and the piston is connected with a piston push rod. The utility model is characterized in that the end part of the piston push rod is connected with a power connector, an eccentric roller working chamber is arranged in the power connector, a motor-driven eccentric roller is arranged in the eccentric roller working chamber, and the eccentric roller can drive the piston push rod to linearly move up and down.
Description
Technical field
The utility model relates to a kind of oil gas and reclaims pump.
Background technique
At present, the piston push rod that existing oil gas reclaims pump is driven by eccentric wheel, and eccentric wheel is by motor driving, and piston can produce swing in cylinder sleeve, not only influence working efficiency, and the wearing and tearing at meeting accelerating piston edge, influences the working life of piston.
The model utility content
Goal of the invention of the present utility model is to provide a kind of oil gas to reclaim pump, high working efficiency, the working life of prolongation piston.
Realize the technological scheme of the present utility model purpose:
A kind of oil gas reclaims pump, has cylinder sleeve, be provided with the piston that can move up and down along inboard wall of cylinder liner in the cylinder sleeve, piston is connected to piston push rod, it is characterized in that: the end of piston push rod is connected to power sub, be provided with eccentric roller work chamber in the power sub, be provided with in the eccentric roller work chamber by motor-driven eccentric roller, eccentric roller can drive piston push rod and do straight line motion up and down.
Upper and lower two cylinder sleeves are set, corresponding have two piston push rods, and the two-piston push rod connects by a power sub.
The beneficial effect that the utlity model has:
The utility model rolls by the off-centre of eccentric roller in eccentric roller work chamber, driving the upper and lower linear type of piston push rod moves back and forth, thereby making piston moving up and down in cylinder sleeve is linear type, there is not swing, significantly reduce the edge abrasion of piston, prolonged the working life of piston, simultaneously, guarantee the even reliability of gas flow, improved working efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 reclaims the schematic representation of the working state one of pump for existing oil gas;
Fig. 3 reclaims the schematic representation of the working state two of pump for existing oil gas;
Fig. 4 is the schematic representation of the utility model working state one;
Fig. 5 is the schematic representation of the utility model working state two.
Embodiment
As shown in Figure 1, upper and lower two cylinder sleeves 1,8 that are provided with, be respectively equipped with the piston 2,7 that can move up and down along inboard wall of cylinder liner in the cylinder sleeve, corresponding have two piston push rods that are connected with piston 3,6, the end of piston push rod is connected to power sub 4, the shared power sub 4 of two-piston push rod links into an integrated entity by power sub.Be provided with eccentric roller work chamber in the power sub, be provided with in the eccentric roller work chamber by motor-driven eccentric roller 5.
As Fig. 4, shown in Figure 5, be example with a piston push rod, eccentric roller is under the drive of motor, the eccentric rolling in eccentric roller work chamber, thereby drive piston push rod and do upper and lower straight line motion, make piston in cylinder sleeve, do upper and lower to-and-fro motion, carry out oil gas and reclaim.
