The oil submerged pump can realize pressurization and oil discharge. The crane tube of an oil submerged pump for a hydraulic discharging trough can effectively overcome an air lock phenomenon and a cavitation phenomenon which are generated in the process of discharging oil.
Description
The utility model relates to a kind of surging and unloads groove submersible pump oil filling riser, belongs to the fluid assembly and disassembly device.
It is many with the oil filling riser kind to unload tank car at present, but because great majority unload oil crane tube at high temperature, very easily produces vapour lock, cavitation phenomenons when groove is unloaded in the infrabar area; Make the various places oil depot have on unloading system, set up other device.Otherwise it is long to overcome the groove time of unloading that causes therefrom, and oil and gas loss is big, and numerous defectives such as potential safety hazard are arranged.
The purpose of the present utility model: aim to provide a kind of oil transportation oil filling riser of new construction, wish that it can not only effectively overcome vapour lock when unloading groove, cavitation phenomenons, and also safe and reliable, efficient.
Above goal of the invention is achieved through the following technical solutions.
This surging unloaded groove submersible pump oil filling riser and formed by unloading oil crane tube (10), submersible pump (4) and hydraulic actuator, it is characterized in that:
Described submersible pump (4) is located at the head of the oil suction pipe (11) of unloading oil crane tube (10); This submersible pump is by fluid power motor (3), and the branch type transport pipe (12) and the pump housing (13) three partly constitute; The described pump housing (13) is a threeway cavity type, and its left and right sides both wings are connected through two arms of fairlead with branch type transport pipe (12), and is responsible for through this branch type transport pipe (12) top and unloads oil crane tube (10) and communicate; Described fluid power motor (3) seat is on pump cover (16), and the housing of this fluid power motor (3) is provided with two hydraulic pressure conduction holes, and the housing inner chamber is provided with one around the shaft drive impeller; Described two hydraulic pressure conduction hole links to each other with malleation delivery line (2) and negative pressure delivery line (1) in the hydraulic actuator respectively, transmission impeller spindle in the fluid power motor housing then passes through pump cover (16) and inserts the pump housing (13) inner chamber, links to each other with another impeller (14) of being located at pump housing inner chamber.
Described hydraulic actuator comprises hydraulic pressure oil tank (8), fire proof motor (7), by pass valve (9), malleation delivery line (2), negative pressure delivery line compositions such as (1), its input end of wherein said malleation delivery line (2) be located in the hydraulic pressure oil tank and linked to each other by the blade-type pump (6) of fire proof motor (7) control, its mouth then links to each other with a hydraulic pressure entrance hole on the fluid power motor housing; Its input end of described negative pressure delivery line (1) directly links to each other with hydraulic pressure oil tank (8), and its mouth another hydraulic pressure entrance hole also direct and on the fluid power motor housing links to each other; Between two positive and negative pressure delivery lines, be provided with simultaneously a by pass valve (9).
Surge according to the such scheme design-calculated and to unload groove submersible pump oil filling riser, generally unload oil crane tube and compare with existing, advantage is: be not subjected to the influence of temperature and air pressure, can thoroughly solve the vapour lock that high temperature, infrabar area produce when unloading groove, cavitation phenomenons.Have efficient height, oil and gas loss little, unload short, safe and reliable, stable working of groove time, advantage such as operation is light, sealing is reliable; And install and use applicable to various dissimilar hair oil platforms.
Accompanying drawing 1 is the utility model structural representation; Accompanying drawing 2 is the submersible pump structural representation.
Each several part member title is as follows among the figure:
The negative pressure delivery line, 2. the malleation delivery line, 3. fluid power motor, 4. submersible pump, 5. filter, 6. blade-type pump, 7. fire proof motor, 8. the hydraulic pressure oil tank, 9. by pass valve, 10. unload oil crane tube, 11. oil suction pipes, 12. branch type transport pipe, 13. pump housings, 14. impellers, 15. containment members, 16. pump covers.
Further describe the utility model below in conjunction with accompanying drawing, and provide embodiment.
Shown in the drawings surging unloaded groove submersible pump oil filling riser and is made up of oil filling riser and submersible pump two large divisions.Its principle of work is to convert electric energy to hydraulic pressure can drive HM Hydraulic Motor, promptly by the pressure oil of blade-type pump output through by pass valve, hand valve, check valve drive impeller (14) rotation in the submersible pump (4).Because this submersible pump (4) is contained on the oil suction pipe (11) of unloading oil crane tube (10) head, makes it subduction and works under oil level.Just because of the pressurization of this submersible pump, use the oil pipe line can oil transportation under higher oil pressure, the air-resistance phenomenon in the time of effectively eliminating the oil filling riser emptying and the cavitation phenomenons of centrifugal oil pump.
Its concrete working process is: in a single day start fire proof motor (7) during work, the blade-type pump of being located in the hydraulic pressure oil tank (8) (6) is started working, high pressure oil stream by its generation flows along malleation delivery line (2), and flow into its cavity by the entrance hole of fluid power motor (3), and simultaneously flow into negative pressure delivery line (1) through another entrance hole of HM Hydraulic Motor (3) again, and finally make oil stream hydraulic return oil tank (8).Have under the effect of pressure reduction oil stream at this, make electric energy become the hydraulic pressure energy, impel the impeller twirl in the HM Hydraulic Motor.Because this impeller is same main shaft with the impeller of being located in the submersible pump (4), thereby the impeller (14) in the submersible pump pump housing (13) is rotated synchronously, thereby can give the oil stream that enters in oil filling riser pressurization, not only eliminate vapour lock but also can quicken oil flow.
Be provided with containment member (15) on main shaft in pump cover (16) and the impeller in the pump housing (14).
