Abstract

The utility model relates to a hydraulic vertical double-cylinder single-action pump, which is characterized in that the utility model is composed of two pumps, wherein, working cylinder sleeves of the two pumps are respectively installed on each pump head vertically, and the working cylinder sleeves are locked tightly by a pressing device. Both ends of each pump head are respectively communicated with valves which control liquid in and out. The valves are respectively connected with a water inlet pipe and a water outlet pipe. Oil cylinder pistons of the two pumps and each cylinder sleeve piston are respectively share one piston rod. A support which is supported right above the cylinder sleeves connects oil cylinders and pump heads into integration, and the support is coaxial with the cylinder sleeves. The utility model has the advantages that the hydraulic vertical double-cylinder single-action pump has simple structure, and the utility model can sufficiently meet the desired petroleum drilling and extracting requirements of long stroke, low stroke frequency, ultra-high pressure, variable flow, high power and low noise.

Description

Hydraulic standing twin-tub single-acting pump

The utility model belongs to a kind of pump, particularly a kind ofly directly drives the vertical twin-tub single-acting pump of drain with hydraulic jack.

It is very difficult that three cylinders that the existing mechanical driving is vertical or horizontal or duplex plunger pump want to satisfy the required long stroke of oil field drilling, low jig frequency, ultrahigh pressure, unsteady flow amount, powerful requirement.

The purpose of this utility model provides the required hydraulic standing twin-tub single-acting pumps of occasion such as a kind of drilling well, well cementation, water filling, pressure break and desalination of sea water, water treatment of suitable petroleum drilling and mining with regard to being to overcome above-mentioned the deficiencies in the prior art.

As above design, the technical solution of the utility model is:

A kind of hydraulic standing twin-tub single-acting pump is characterized in that: be made up of two pumps, wherein the work cylinder sleeve of two pumps is vertically mounted on respectively on separately the pump head, and the locking of compacted device; The two ends of each pump head communicate with the valve of controlling liquid turnover respectively; Valve respectively and be connected in inlet tube and outlet tube; The oil cylinder piston of two pumps respectively with the shared piston rod of piston of cylinder sleeve separately; The support that is supported on directly over the cylinder sleeve fuses oil cylinder and pump head, and this support is coaxial with cylinder sleeve;

The utility model has the advantages that: 1, in light weight, take up an area of less, cost is low,, easily carrying.2, can fully satisfy the required long stroke of petroleum drilling and mining, low jig frequency, ultrahigh pressure, unsteady flow amount, high-power, low noise requirement.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is a section of structure of the present utility model

Fig. 2 is the sectional view at the A-A place of Fig. 1

As shown in the figure, two oil cylinders (4) are arranged vertically directly over the same axis of upright cylinder sleeve (1), oil cylinder piston (6) and the shared piston rod of cylinder sleeve piston (7) (8); The compacted device of cylinder sleeve (9) is fixed on the pump head (2); The pump head two ends communicate with the valve (3) of controlling liquid turnover; Under the effect of the hydraulic coupling of oil cylinder, long stroke low jig frequency ground drives the cylinder sleeve piston liquid is discharged; Two oil cylinders are done continuously at the uniform velocity straight line intersection to-and-fro motion under the control system effect, make the synthetic flat curve of flow time graph of two cylinder sleeve discharge opeings, have saved traditional air tank and have reduced noise; Support (5) links into an integrated entity oil cylinder and pump head, and the support reaction during oil cylinder work acts on the pump head by support, constitutes seal force system, and the weight of externally removing pump does not show the effect of power, has saved common pump case and Infrastructure.The hold down gag (9) that open, locking guarantees sealing, cylinder sleeve and piston that can rapid complete replacing different-diameter obtain needed high pressure or become discharge capacity output.With the twin cylinder pump is the unit, and it is in parallel that intake pipe (10) and outlet pipe (11) are arranged to the turnover water pipe that is easy to another unit, and the total output of pump can be doubled, and very easily forms tandem product, satisfies different needs, and maintenance easily.

Claims

1, a kind of hydraulic standing twin-tub single-acting pump is characterized in that: be made up of two pumps, wherein the work cylinder sleeve of two pumps is vertically mounted on respectively on separately the pump head, and the locking of compacted device; Each pump head two ends communicates with the valve of controlling liquid turnover respectively; Valve respectively and be connected in inlet tube and outlet tube; The oil cylinder piston of two pumps respectively with the shared piston rod of piston of cylinder sleeve separately; The support that is supported on directly over the cylinder sleeve fuses oil cylinder and pump head, and this support is coaxial with cylinder sleeve.
