Description
Technical field
It the utility model is related to booster pump field, more particularly to a kind of Pneumatic booster pump.
Background technology
At present, booster pump is widely used in the professional hydraulic fittings such as valve, pipe fitting, pressure vessel, existing booster pump
Complicated, stability is poor, the situation of card valve easily occurs when work, work efficiency is low, in addition, a kind of existing band
There is an air-cylinder type booster pump of resetting spring, but the restoring force due to compound spring and unstable, the elastic force of spring can also be because of bullet
Property it is tired and reduce, so pressure that booster pump produces and unstable, while spring easily produces noise when promoting piston, close
Envelope property is poor, also difficult in terms of maintenance.
Utility model content
Goal of the invention：Original boosting pump structure to be solved in the utility model is complicated, and stability is poor, poor sealing and work
Make the low technical problem of efficiency, the utility model provides a kind of Pneumatic booster pump.

Lower end be connected with bottom end cover, be bolted to connection, be equipped with the cylinder barrel big living between the upper end cover and bottom end cover
Plug and small plunger, the big piston are fixedly connected with small plunger, and plunger cavity, pressing sleeve, oil inlet are equipped with the bottom end cover and is gone out
Hydraulic fluid port, the small plunger go deep into plunger cavity, the pressing sleeve be arranged on small plunger both sides, the oil inlet and oil outlet respectively with
Plunger cavity is connected, and the outside of the upper end cover is connected with air operated reversing valve, and air admission hole, institute are equipped with the air operated reversing valve
The muffler that is externally connected to of air operated reversing valve is stated, the outside of the bottom end cover is equipped with fixed block, is equipped with the fixed block logical
Stomata, is connected with tracheae between the air operated reversing valve and venthole, be equipped with the cylinder barrel and stretch out upper end cover and bottom end cover
Guide switch, the bottom end cover are equipped with mounting hole.
Further, whole junctions of the upper end cover and air operated reversing valve use O-ring sealing means.
The utility model has the advantages that a kind of Pneumatic booster pump is simple in structure, simple operation, passes through gas drive guide's switching valve
Control, using the area of piston and small plunger ratio, realizes that reciprocation cycle is moved, and pressure increase is relatively strong under pump housing sealing, reduces
The probability of gas leakage, stability is good, and work efficiency is high.
