Abstract
The utility model discloses an oil suction pipe for a gear pump, and belongs to the field of the oil suction pipe. The oil suction pipe for the gear pump comprises a hose and further comprises a sleeve and a bulb, wherein the sleeve is sleeved on the hose; the bulb is located at one end close to the sleeve of the hose; a joint core is arranged between the bulb and the hose; the joint core and the hose are the same in size; the inner diameter of the hose is 15-20mm. The oil suction pipe for the gear pump provided by the utility model has the advantages of reasonable design, small oil suction resistance, suitable flow velocity, strong sealing property and long service life; the flow standard further can be met.
Description
Technical field
The utility model relates to a kind of fuel sucking pipe, relates in particular to a kind of for the fuel sucking pipe on gear pump.
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.
Summary of the invention
the problem that 1, will solve
Unreasonable for existing gear pump fuel sucking pipe design, be prone to flow and do not reach standard, the faults such as wheel pump generates heat, bursts, and the problem such as fuel sucking pipe working life is shorter, the utility model provides a kind of gear pump fuel sucking pipe, after its appropriate design, reduce oil suction resistance, flow velocity is suitable, also can meet flow standard, and increases the working life of fuel sucking pipe by zinc-plated and increase alloy sleeve.
2, technological scheme
For addressing the above problem, the utility model adopts following technological scheme.
A kind of gear pump fuel sucking pipe, comprises flexible pipe, also comprises sleeve, bulb, and described jacket casing is on flexible pipe; Described bulb is positioned at one end near sleeve on flexible pipe; Between described bulb and flexible pipe, be provided with joint core; The size of described joint core and flexible pipe consistent size; The internal diameter of described flexible pipe is 15 ~ 20mm.
Preferably, described joint wicking surface is also coated with zinc layer, and zinc coating thickness is 0.5 ~ 1.5mm.
Preferably, described sleeve is steel part, or alloy steel piece.
In the utility model, flexible pipe adopts bulb joint, can increase the sealing of flexible pipe; 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; Oil pipe surface cover has alloy sleeve, can increase the working life of oil pipe; Joint wicking surface is zinc-plated, can effectively prevent that flexible pipe from getting rusty, and increases the working life of flexible pipe equally.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model side sectional view;
Number in the figure explanation: 1, flexible pipe; 2, sleeve; 3, joint core; 4, bulb.
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.
A kind of gear pump fuel sucking pipe, comprises flexible pipe 1, also comprises sleeve 2, bulb 4, and described sleeve 2 is enclosed within on flexible pipe 1; Described bulb 4 is positioned at one end near sleeve 2 on flexible pipe 1; Between described bulb 4 and flexible pipe 1, be provided with joint core 3; The size of described joint core 3 and flexible pipe 1 consistent size; The internal diameter of described flexible pipe 1 is 18mm.
In addition, joint core 3 surfaces are also coated with zinc layer, and zinc coating thickness is 1mm.Sleeve 2 is alloy steel piece.
With embodiment 1, difference is that the internal diameter of flexible pipe is 15mm, and zinc coating thickness is 0.5mm.
