Abstract
The utility model provides an oil-water power converting hydraulic cylinder which is applied to transfer the hydraulic power for a long distance and is characterized in that two ends of an oil pressure power cylinder body are provided with a power fluid outlet A and a power fluid outlet B; the oil pressure power cylinder is fixed on a support frame; a water medium cylinder is fixed on the support frame, a cylinder rod of the oil pressure power cylinder is connected with a plunger piston of the water medium cylinder; the cylinder wall of the water medium cylinder is fixed with a water inlet and a water outlet, and a pipeline of the water outlet is connected with a non return valve. The oil-water power converting hydraulic cylinder has the advantages that two sets of hydraulic cylinders are adopted to transfer the hydraulic power to separate oil from water in power fluid; a hydraulic power station provides power for the oil pressure power cylinder; a piston of the oil pressure power cylinder reciprocates to drive the piston of the water medium cylinder to reciprocate; and the water medium cylinder can provide reciprocating power for an executing mechanism. Because the water medium cylinder is connected with the water inlet with a one-way valve, the water medium cylinder can provide the reciprocating power for the executing mechanism and compensates working medium loss in the working process of the executing mechanism.
Description
Technical field
The utility model relates to the liquid technical field, and particularly a kind of pressure transmits match equipment, be a kind of be the hydraulic element that medium is converted to aqueous medium with hydraulic oil.Be mainly used in remote delivery hydraulic pressure power,, hydraulic oil power be converted to hydrodynamic force, be transferred to the underground hydraulic pressure pump, drive oil hydraulic pump and recover the oil on ground as the hydraulic oil producing technical field.
Background technique
At present, many oil wells adopt hydraulic oil producing.Hydraulic oil producing have pump hang dark, lift height, advantage such as discharge capacity is big, and is applied widely.The hydraulic oil producing system is divided into two kinds of open-cycle system and closed circulation systems.Open-cycle system is that weary power fluid mixed with stratum production fluid (crude oil), gives rise to ground by the annular space between sleeve pipe and the oil pipe after high voltage power liquid arrived the work of down-hole driving oil well pump.Closed circulation system has independently reflux pipeline, does not mix with the stratum production fluid when the weary power fluid of backflow returns ground, and independently Returning pipe is arranged.
The Chinese patent publication number is CN1450247, and a kind of Rodless hydraulic oil pumping system is provided, and combines the advantage of two kinds of hydraulic oil producing systems.Do not mix when promptly the weary power fluid of Hui Liuing returns ground, reduced the reflux pipeline of a closed circulation system again with the stratum production fluid.In this invention, adopt the profit isolator, hydraulic oil power is converted to hydrodynamic force is transported to the underground hydraulic pressure oil well pump.
In remote hydraulic power transmission course, frequent dynamic liquid leakage needs to replenish hydraulic oil, causes the cost of material economic loss.
The model utility content
The purpose of this utility model is: a kind of profit power-converting oil hydraulic cylinder is provided, and just hydraulic oil power is converted to hydrodynamic force, and oil, hydrodynamic force liquid are kept apart.Can in time replenish the working medium of missing in actuator's working procedure.
The technical solution adopted in the utility model is: profit power-converting oil hydraulic cylinder mainly is made up of oil pressure ram, plunger, aqueous medium cylinder and one-way valve.The dynamic liquid import in the two ends A of oil pressure ram cylinder body and outlet B.It is characterized in that: the oil pressure ram is fixed on the supporting frame; The aqueous medium cylinder is fixed on the supporting frame, and the piston rod of oil pressure ram is connected with the plunger of aqueous medium cylinder.On the casing wall of aqueous medium cylinder, be fixed with water intake and water outlet, on the pipeline of water intake, be connected with one-way valve.
In order to improve the maintenance of aqueous medium cylinder, the piston rod of oil pressure ram is connected by positioning block with the plunger of aqueous medium cylinder and connects.When maintain and replace aqueous medium cylinder Sealing, positioning block can be pulled down, plunger and seal just can take out from supporting frame.
For improving the sealing of aqueous medium cylinder, between aqueous medium cylinder and plunger, Sealing is arranged.
In order to control aqueous medium cylinder water outlet flow, on control aqueous medium cylinder water outlet pipeline, be connected with ball valve.
The beneficial effects of the utility model: the utility model profit power-converting oil hydraulic cylinder, adopt between the two cover cylinder devices and transmit hydraulic power, oil, hydrodynamic force liquid are kept apart.Provide power by hydraulic power erect-position oil pressure ram; The reciprocating motion of the pistons of oil pressure ram drives the plunger to-and-fro motion of aqueous medium cylinder; The aqueous medium cylinder can provide reciprocating power for actuator.Because the water intake of aqueous medium cylinder connecting band one-way valve when aqueous medium can provide reciprocating power for actuator, in time replenishes the water of missing in actuator's working procedure.By profit power-converting oil hydraulic cylinder, make the energy of hydraulic oil offer WATER AS FLOW MEDIUM like this, aqueous medium drives just oil pump of down-hole.Even aqueous medium has leakage, the supplementing water medium can not cause economic loss.
