Abstract
The utility model discloses a manual oil pump which can be used for the motive power of hydraulic elevating mechanisms, pressure test systems or other execution mechanical elements, comprising an oil pump body, a piston body, a check valve and a manual reversal valve. When a piston rod moves upward, oil is absorbed into a lower oil chamber, and oil liquor in an upper oil chamber is discharged from the oil pump; when the piston rod moves downward, a part of the oil liquor in the lower oil chamber enters the upper chamber and the other is discharge from the oil pump. Because of the reciprocation of motion, the continuity of oil pump feed is kept.
Description
The present invention proposes a device, can be used as the power of hydraulic pressure lift machinery, pressure testing system or other execution mechanical component.Belong to mechanical field.
Known hand oil pump.Flow is little, speed is slow, the fuel feeding direction is single, operating efficiency is low.At above-mentioned deficiency, the present invention propose one can be successively to the oil pump of both direction fuel feeding.Two the action request ， And and the fuel feeding that satisfy executive component are continuous, make to carry out that action is stable, speed is fast.Accompanying drawing is the structural drawing of oil pump.
Structural feature of the present invention is: oil header 1 and one-way valve 13 are housed on the lower end cap 12 of oil pump body 9, an one-way valve 10 of connecting upper oil cavitie 8 and lower oil cavitie 11 is equipped with in piston rod 7 underparts, one-way valve 5 is equipped with in oil outlet 4 inboards, and a hand-operated direction valve 3 from priority to the both direction fuel feeding that can control is equipped with in the outside.
Technical characteristics of the present invention is: stick up bar 6 and drive piston rod 7 motions, when piston rod 7 moves upward, oil through oil header 1 enter from fuel tank 2 one-way valve 13 suck lower oil cavities 11 simultaneously the fluid in the upper oil cavitie 8 from one-way valve 5 through oil outlet 4, enter hand-operated direction valve 3 and discharge oil pump, fluid when piston rod 7 moves downward in the lower oil cavitie 11 is through being contained in the one-way valve 10 of piston rod 7 underparts, a part enters upper oil cavitie 8, another part is the fluid of lower oil cavitie 11 and upper oil cavitie 8 difference in volume,, enter hand-operated direction valve 3 and discharge oil pump through oil outlet 4 from one-way valve 5.Piston rod has up and down reciprocatingly kept the continuity of oil pump feed.The hand-operated direction valve 3 of oil pump oil outlet 4 places dresses guaranteed oil pump can be successively with same form to the both direction fuel feeding.
Claims (1)
- A kind of hand oil pump that hydraulic oil is provided for actuator.Form by oil pump body piston rod, one-way valve, hand-operated direction valve, it is characterized in that:(1) one-way valve 13 is equipped with in piston rod 7 lower ends, can form upper and lower two oil pockets when making piston rod 7 motions in oil pump.(2) along with piston rod 7 upper and lower motions, oil pump feed is continuous.When moving downward, the oil of discharge is the fluid of the difference of upper and lower two oil pocket volumes; The oil of discharging when moving upward is the fluid of upper oil cavitie 8.
