Abstract
The utility model relates to an oil suction pipe, and in particular relates to a gear pump oil suction pipe with sheaths. The oil suction pipe comprises a hose (1) as well as sleeves (2), a bulb (3), a screw cap (4) and a connector core (6), wherein two sleeves (2) are provided and are respectively sleeved at two ends of the hose (1); the bulb (3) and the screw cap (4) are respectively connected with two ends of the hose (1); the bulb (3) and the hose (1) are connected through the connector core (6); the surface of the middle part of the hose where no sleeves are arranged are further provided with sheaths (5); the inner diameter of the hose (1) is 18mm. As the sleeves and spring sheaths are additionally arranged on the surface of the hose to protect the hose, the oil suction pipe is long in service life; as the bulb is adopted for a connector, the sealing capability of the hose is improved.
Description
Technical field
The utility model relates to a kind of fuel sucking pipe, relates in particular to a kind of gear pump fuel sucking pipe with sheath.
Background technique
Gear pump is the mutual rolling engagement of the involute gear identical with structure by a pair of parameter, the low pressure oil in fuel tank is risen to the vitals of the high pressure oil that can do work, and is the power plant that the mechanical energy of motor converted to hydraulic energy.Gear pump often there will be flow not reach standard in running, and wheel pump such as generates heat, bursts at the fault, in order to eliminate these faults, need to adopt various measures, wherein particularly important for the design of fuel sucking pipe.
Existing fuel sucking pipe is generally the simple structure that a tube end is screwed on a flexible pipe, and is connected with gear pump inlet port by flange, and fuel sucking pipe is not provided with protective measure, thereby is prone to the phenomenon such as breakage, cracking, and working life is shorter; Employing flange connects, and the sealing of pipeline need to improve.
Chinese Patent Application No.: 201210196352.X, open day: on October 03rd, 2012, disclose the patent document that a name is called a kind of Oil pump electrical machinery fuel sucking pipe.This invention comprises the flange plate being connected with Oil pump electrical machinery, and steel pipe, hose coupling, is characterized in that, this flange plate is weldment, one end welding of its one end and steel pipe, the other end of steel pipe and the welding of hose coupling one end, the hose coupling the other end is made the screw mouth matching with flexible pipe; Described flange plate end face has a seam matching with Oil pump electrical machinery inlet port flange; The Oil pump electrical machinery fuel sucking pipe of this invention uses on Oil pump electrical machinery, comes compared with common fuel sucking pipe, obviously uses light, fast, and cost is low.But this invention is the simple combination of steel pipe and flexible pipe, and adopt flange to be connected with oil pump inlet port, working life is shorter, seals also poor.
Summary of the invention
the problem that 1, will solve
Design for existing gear pump fuel sucking pipe is only the simple combination of steel pipe and flexible pipe, is not provided with protective measure, is prone to the phenomenon such as breakage, cracking; Adopt flange to be connected with oil pump inlet port; the problem that sealing is lower; the utility model provides a kind of gear pump fuel sucking pipe with sheath; it is by protecting flexible pipe at hose surface increase sleeve and spring protecting sleeve; high life; and joint adopts bulb, can effectively increase the sealing of flexible pipe.
2, technological scheme
For addressing the above problem, the utility model adopts following technological scheme.
With a gear pump fuel sucking pipe for sheath, comprise flexible pipe, also comprise sleeve, bulb, nut and joint core, described sleeve has two, is enclosed within respectively the two ends of flexible pipe; Described bulb, the two ends that nut is connected to flexible pipe; Between described bulb and flexible pipe, be connected by joint core; The surface, intermediate portion that described flexible pipe is not established sleeve is also overlapped and is had sheath; The internal diameter of described flexible pipe is 15 ~ 20mm.
Preferably, the sheath on described surface, flexible pipe intermediate portion is nylon sheath wire.
Preferably, described joint wicking surface is all coated with zinc layer, and zinc coating thickness is 0.5 ~ 1.5mm.
Preferably, described sleeve is alloy steel piece.
3, beneficial effect
Than prior art, the beneficial effects of the utility model are:
(1) the utility model comprises sleeve, nylon sheath wire, jacket casing is at the two ends of flexible pipe, the intermediate portion that nylon sheath wire is enclosed within flexible pipe does not establish sleeve, the mode that adopts hose surface to increase sleeve and nylon sheath wire is protected flexible pipe, and sleeve is alloy steel piece, can effectively avoid flexible pipe to occur the phenomenons such as breakage, cracking, increase flexible pipe working life;
(2) the utility model also comprises bulb, adopts bulb as hose coupling, can effectively increase the sealing of flexible pipe;
(3) in the utility model, the internal diameter of flexible pipe is 15 ~ 20mm, and the internal diameter of flexible pipe is reasonable in design, there will not be oil pipe heating, flow meticulous and that cause not to reach the phenomenons such as standard;
(4) the utility model middle joint wicking surface is all coated with zinc layer, and zinc coating thickness is 0.5 ~ 1.5mm, can effectively prevent that flexible pipe from getting rusty, and increases the working life of flexible pipe equally;
(5) the utility model is simple in structure, easy to operate, is easy to manufacture.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model plan view.
Number in the figure explanation: 1, flexible pipe; 2, sleeve; 3, bulb; 4, nut; 5, sheath; 6, joint core.
Embodiment
For further understanding content of the present utility model, below in conjunction with Figure of description and specific embodiment, the utility model is described in detail.
With a gear pump fuel sucking pipe for sheath, comprise flexible pipe 1, also comprise sleeve 2, bulb 3, nut 4 and joint core 6, described sleeve 2 has two, is enclosed within respectively the two ends of flexible pipe 1; Described bulb 3, the two ends that nut 4 is connected to flexible pipe 1; Between described bulb 3 and flexible pipe 1, be connected by joint core 6; The surface, intermediate portion that described flexible pipe 1 is not established sleeve 2 is also overlapped and is had sheath 5; The internal diameter of described flexible pipe 1 is 18mm.
In addition, the sheath 5 on described flexible pipe 1 surface, intermediate portion is nylon sheath wire.Described joint core 6 surfaces are all coated with zinc layer, and zinc coating thickness is 1mm.Described sleeve 2 is alloy steel pieces.
When use, directly bulb 3 is connected with the inlet port of gear pump, can realizes the oil suction of fuel sucking pipe.Wherein bulb 3 joints can effectively guarantee the sealing that inlet port connects; Flexible pipe 1, under the protection of alloying steel sleeve 2 and nylon sheath wire 4, can effectively avoid flexible pipe to occur the phenomenons such as breakage, cracking, and flexible pipe improves working life greatly.
