Abstract
The utility model relates to a double-acting crude oil transmission piston pump belonging to field of a reciprocating pump, which comprises a power end part and a hydraulic end part. The power end part comprises a small gear shaft and a camshaft. The characteristics of the double-acting crude oil transmission piston pump are as follows: the power end part is a dual-gear transmission structure; the small gear shaft is provided with two small gears of the same specification; the camshaft is provided with two large gears of the same specification which are meshed with the small gears; two connecting rod with the same direction are arranged on the camshaft and are connected with the hydraulic end part which are bi-directional intake/drain liquid valves. The double-acting crude oil transmission piston pump solves defects of large volume and low work efficiency existing in the piston pump in prior art, has advantages of simple and compact structure, small volume, convenient maintenance, large flow rate, high volumetric efficiency, smooth and reliable work, and can be widely applied to oilfield and other places needing high-pressure water injection so as to meet requirements of oil transmission in oilfield.
Description
Technical field
The utility model belongs to the reciprocating pump field, is specifically related to a kind of double-action Crude Oil Transportation reciprocating pump.
Background technique
In oil transportation field, oil field, be extensive use of reciprocating pump.But traditional reciprocating pump is because structural imperfection, exist big, the ineffective shortcoming of volume, its reason mainly is because traditional piston pump power end parts adopt single geared drive, its gear shaft unbalance stress, be head it off, can only cause overall volume big the gear shaft overstriking, the occupied ground area be bigger; Its fluid end parts adopt unidirectional feed liquor valve, and flow is little, inefficiency.
The model utility content
The purpose of this utility model is to solve the prior art reciprocating pump and exists big, the ineffective defective of volume, provide a kind of rational in infrastructure, volume is little, stressed double-action Crude Oil Transportation reciprocating pump even, easy to maintenance.
The utility model is achieved through the following technical solutions:
It is a kind of double-action Crude Oil Transportation reciprocating pump, comprise power end parts, fluid end parts, the power end parts comprise pinion shaft, camshaft, it is characterized in that the power end parts are bidentate wheel drive mechanism, pinion shaft is provided with the small gear of two same sizes, and camshaft is provided with the gearwheel with two same sizes of pinion, and camshaft is provided with two equidirectional connecting rods, two connecting rods all are connected with the fluid end parts, and described fluid end parts are two-way combination valve.
Two small gear symmetries on the pinion shaft are distributed in the two ends of pinion shaft.
Two groups of gears of the utility model power end parts are connected by the belt pulley of installing on belt and the pinion shaft.Simultaneously stressed because of the camshaft two ends in transmission process, improved the stressed of camshaft and pinion shaft, reduced the situation of camshaft and little camshaft unbalance stress.Under identical force-bearing situation, alleviating of camshaft weight reduces overall volume, saved the space, reduced energy consumption.
The fluid end parts have adopted two-way combination valve, and two-way combination valve is that the combination valve of two symmetries is formed, installation, easy maintenance, and flow is big, and efficient improves, and is convenient to transportation.
The utlity model has simple and compact for structure, volume is little, easy to maintenance, flow is big, volumetric efficiency is high, the reliable advantage of stable working, the utility model can be widely used in the place of need high pressure water injections such as oil field to satisfy the needs of oil field oil transportation.

Embodiment
With embodiment the utility model is described further in conjunction with the accompanying drawings.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, support 1 right-hand member is provided with motor 2, the rotating shaft of motor 2 is by belt 3, big belt pulley 4 is connected with power end parts 5, power end parts 5 comprise upper box 5-1, lower box 5-4, pinion shaft 5-2, camshaft 5-3, big belt pulley 4 is fixedly installed togather with pinion shaft 5-2, pinion shaft 5-2 is provided with the small gear 5-5 of the same size of two symmetry installations, the gearwheel 5-6 that camshaft 5-3 is provided with two same sizes and meshes with small gear 5-5, camshaft is provided with two connecting rods 6, power end parts 5 are connected with fluid end parts 8 by connecting rod 6, fluid end parts 8 are two-way combination valve, the combination valve of two symmetries of described two-way combination valve is formed, and is provided with separately piston assembly and check valve assembly.
When the utility model used, motor 2 rotated, and rotated by the synchronous drive of belt 3 drives big belt pulley 4, pinion shaft 5-2, again by two couples of pitch wheels drive camshaft 5-3 rotation, the to-and-fro motion of realization piston assembly 8-1.
