Abstract
The utility model relates to a straight-line pneumatic pump providing oil hydraulic power, which is mainly characterized in that on the tunnel wall of a cylinder, a gas passage is arranged between a ring groove and a discharge valve rod on a piston; a plurality of exhaust vents are arranged on a backseat, through which the gas in the gas plug is directly guided in, and a passage arranged on the backseat is connected with the corresponding amount of exhaust vents on the cylinder lid. The utility model has the following advantages: the design of the air intake and discharge return circuit makes the overall inner structure simple and practical and shortens the trip period of the pump body and the air inlet and discharge velocity is high.
Description
Technical field:
The utility model relates to a kind of pneumatic pump device that is used to provide oily power, and the improvement structure that refers in particular to its gas flow loop device is to provide oil pressure power fast.
Background technique:
At present, be used for the pneumatic slurry global design complex structure that oily jack oil presses power, intake and exhaust speed is slower.
Summary of the invention:
The purpose of this utility model is to overcome above deficiency and a kind of simple in structure and intake and exhaust pneumatic pump at a high speed is provided.
The utility model is achieved by the following technical solution: this direct-exhausting type pneumatic pump, comprise cylinder head, venting valve rod, back seat, piston, cylinder barrel, piston rod, O RunddichtringO, envelope vent plug and cylinder spring etc., its major technique feature is to be provided with gas channel between the valve rod at the annular groove place of piston with exitting on the described cylinder barrel; Described back seat is provided with several exhaust ports, directly imports the gas of the envelope vent plug of opening, and communicates at the exhaust port that is provided with respective numbers on passage and the cylinder head on the back seat.
The utlity model has following advantage: by the design of intake and exhaust body loop, make whole interior simple and practical, shorten the pump housing stroke cycle, intake and exhaust speed is fast.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2, Fig. 3, Fig. 4 are respectively the working principle sectional view of each action of cylinder.
Embodiment:
As shown in Figure 1 and Figure 2, pressurized gas enter cylinder body by the inlet hole on the back seat 3, because the pressure of pressurized gas, piston 4 and the part that connected thereof are pushed open, and pressurized gas enter compression chamber.This is action one.
As shown in Figure 3, when piston element moves to the special annular air bleed slot that cylinder barrel is provided with, because the effect of " O " RunddichtringO imports venting valve rod path 10 on several cylinder barrel 5 walls and the back seat with pressurized gas, enter the space at venting valve rod 2 and back seat, cylinder head place, push venting valve rod by pressurized gas this moment, and the envelope vent plug 8 of bleed valve club head breaks away from sealing station.For exhaust creates conditions.
As shown in Figure 4, when envelope gas portion plug 8 broke away from sealing station, high-pressure air directly entered several exhaust ports that design on the back seat by the envelope vent plug of opening, and discharged cylinder body through passage 11 and by the exhaust port of the respective numbers on the cylinder head.Because this kind exhaust mode is for directly by the back seat exhaust, cavity without cylinder spring place, and this design all air-flows in exhaust process are unified the flow direction, and the effect because of spring when piston element recovers the home position makes cylinder originally produce air pressure as the gas of getting rid of in the compression chamber, help to produce certain exhaust pressure, thereby assist cylinder to accelerate exhaust.
So far, the complete complete working stroke of our model utility reaches moving back and forth to other structure provides of core 6 of gas slurry with this and continuously has the required oil pressure power of work.Above structure is the direct exhaust of high-pressure air, to reach the purpose of quick work, has improved working efficiency.
Claims (2)
