Description
Technical field
The utility model relates to oil pump, particularly relates to the anti-self-locking oil pumping device of a kind of auto-manual.
Background technique
On some important big machinery vehicles, be configured with various oil pump and hydraulic oil container, the mutual close cooperation between them makes working efficiency greatly improve.Because different oil pump may need the hydraulic oil of different size.In maintenance, when needing to carry out manual servicing fluids force feed to it, because its oil pump is connected with other accessories, need to dismantle all the other component be attached thereto, cause work efficiency drop.Often needing frequent starting when keeping in repair, being closed in hydraulic equipment power source, the waste of a large amount of hydraulic oil and the energy of vehicle own can be caused; Or when hydraulic power system paralysis cannot provide dynamicliquid pressure, just more difficult to the maintenance of oil circuit, greatly delay engineering progress.
Therefore designing a kind of auto-manual anti-self-locking oil pumping device is a kind of good selection, and auto-manual anti-self-locking oil pumping device is on the basis of traditional oil pump, the simple modifications of carrying out.When frequent starting hydraulic power supply or hydraulic system power system are not paralysed, manual pump oil can be carried out, connect third party's power source after not needing and associate member dismounting overall to oil pump and power is provided, can overhaul oil circuit, avoid the waste of a large amount of hydraulic oil.When not needing manual pump oil, only need pull down ball handle, work can be carried out as common oil pump.This device has that structure is simple, convenient disassembly, provide that dynamic range is adjustable, hand self mode switches the good advantage of random, anti-self-locking property.
Summary of the invention
The purpose of this utility model is to solve the problem, and provides that a kind of structure is simple, the anti-self-locking oil pumping device of auto-manual of convenient disassembly.The technical scheme in the invention for solving the above technical problem is:
The anti-self-locking oil pumping device of a kind of auto-manual, comprise the pump housing, the pump housing is built with two gears; Described gear is spur gear; The two ends of described gears meshing have and have oil outlet and filler opening respectively; Described oil outlet one end is connected with flow-limiting valve; Described gear and handle sealing seat one share a transmission shaft; Described handle sealing seat has tapped hole; Described handle sealing seat is fixed with ball handle.
Described pump housing two ends have filler opening and oil outlet, and have identifier declaration, avoid coupled device connection error.
Axle and the pump housing endoporus of described two gears are Spielpassung, and good gear is spur gear.
Described seal ring is wear-resistant O RunddichtringO, left and right end cap press seal circle.
Described ball handle has 4, is in 90 degree, and decreased food is 20cm, and one end is provided with spherical rubber block.
The beneficial effects of the utility model are: (1), by the structural design to the anti-self-locking oil pumping device of auto-manual, makes whole apparatus structure simple; (2) by the structural design to the anti-self-locking oil pumping device of auto-manual, good self-locking property is made it have; (3) by the structural design to the anti-self-locking oil pumping device of auto-manual, make the dynamic range of output adjustable flexibly.

In figure: 1, gear one, 2, locating stud, 3, ball handle, 4, handle sealing seat, 5, seal ring, 6, right end cap, 7, gear two, 8, transmission shaft, 9, bolt, 10, left end cap; 11, the pump housing.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, the anti-self-locking oil pumping device of a kind of auto-manual described in the utility model, comprises gear 1, locating stud 2, ball handle 3, handle sealing seat 4, seal ring 5, right end cap 6, gear 27, transmission shaft 8, bolt 9, left end cap 10.The pump housing 11, built with gear 1 and gear 7, is spur gear; The two ends of gears meshing have and have oil outlet and filler opening respectively; Oil outlet one end is connected with flow-limiting valve; Ball handle 3 is fixed on handle sealing seat 4, and handle sealing seat 4 shares a transmission shaft 8 with gear one.
The described pump housing 11 two ends have filler opening and oil outlet, and have identifier declaration, positive hour hands and be rotated counterclockwise time corresponding oil outlet and filler opening inconsistent.
Axle and the pump housing endoporus of described gear 1 and gear 27 are Spielpassung, and two gears are spur gears, and when transmission shaft 8 sense of rotation changes, driving wheel and follower are changes.
Described ball handle 3 has 4, is in 90 degree, and decreased food is 20cm, and one end is provided with spherical rubber block.
Described handle sealing seat 4 has tapped hole, is used for dismantling ball handle 3.
Described seal ring 5 is wear-resistant O RunddichtringO, left and right end cap press seal circle.
Described ball handle 3 handle sealing seat 4, before being switched to automatic mode, must be removed, and prevents from damaging oil pump shaft and people.
During work, when hydraulic system pipeline normally works, oil hydraulic pump is automatic pump oil pattern, and filler opening and oil outlet normally work.When hydraulic circuit breaks down, not starting vehicle provides hydraulic power, after reducing maintenance range, just can be arranged on handle sealing seat 4 respectively by 4 ball handles 3; By the filler opening of the hydraulic oil container mouth of pipe for subsequent use for hydraulic pressure access pump and oil outlet, one end of oil outlet connects a flow-limiting valve, rises and prevents the excessive oil pump gear of oil pressure stuck; When staff rotates ball handle 3 by set sense of rotation, ball handle 3 drives transmission shaft 8, and gear 1 drives driven gear 7 as driving tooth, and oil pump just starts manual work.The pressure of pump oil is relevant with the speed speed of manual rotation.When needs from hydraulic circuit oil suction out time, only need adjustment ball handle 3 sense of rotation.In a manual mode, the frequent starting of hydraulic power unit and the waste causing a large amount of hydraulic oil can be avoided.After maintenance, the pipeline can pulling down filler opening and oil outlet takes back on original system, pulls down handle sealing seat 4 and ball handle 3 simultaneously, and start power plant rear gear pump and start automatic mode pump oil, transmission shaft 8 dallies.From the above mentioned, the automatic mode of gear pump and the random switching of manual mode can just be carried out.
More than show and describe basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
