Description
Technical field
The utility model relates to a kind of pneumatic pump structure, belongs to the pneumatic pump technical field.
Background technique
Existing is the pneumatic pump of power source with the compressed gas source, constitute by housing, cylinder, cylinder piston, control valve etc., and by elastic element, control valve, seal element, guiding valve are set in housing, cylinder piston and oil pump piston are set in cylinder, slide valve buckle is on control valve body, between guiding valve and control valve, seal element is housed, in control valve, be provided with air chamber and outlet valve, suction valve, suction valve is arranged on the outlet valve the inside, all is provided with pore at housing, control valve, guiding valve, cylinder piston.Though this pneumatic pump will be the cylinder of power source with the compressed gas source and be connected as a single entity by the reciprocating pump that cylinder piston drives pump piston work,, complex structure, the pore pipeline is many, easily causes gas path failure, influences the service behaviour of pneumatic pump.
The model utility content
The purpose of this utility model is exactly the deficiency that exists at existing pneumatic pump, provides a kind of simple in structure, the integrated type pneumatic pump that usability is good.
The purpose of this utility model is to realize like this, the integrated type pneumatic pump, comprise that cylinder that the cylinder piston that is provided with in the cylinder liner constitutes and piston rod are connected the reciprocating pump on the cylinder piston, the two ends of described cylinder liner 1 are respectively equipped with spring 2,3, the two ends of cylinder piston 4 are respectively equipped with commutation valve plate 5,6, the import of reciprocating pump is provided with two one-way valves 7,8, is provided with bearing support 11 between the cylinder and piston pump and connects.Described cylinder piston 4 is provided with axial pore 9,10.Be provided with conical surface seal between commutation valve plate 5 and the pore 9.Be provided with the flat rubber sealing between commutation valve plate 6 and the pore 10.Between commutation valve plate 5 and the commutation valve plate 6 is to be rigidly connected by screw rod 16.
The utility model simple compactness rational in infrastructure is manufactured easily, and cost is low, and cylinder piston to-and-fro motion control mode is reasonable, and the pore that is provided with on the cylinder piston is straight hole, and vent ability is good, improves the service behaviour of pump.
Description of drawings
Accompanying drawing is a structural representation of the present utility model, and cylinder liner 1 among the figure, spring 2,3, cylinder piston 4, commutation valve plate 5,6, one-way valve 7,8, axial pore 9,10, bearing support 11, piston rod 12, pump case 13, suction port 14, air outlet 15, screw rod 16.
Embodiment
Cylinder piston 4 is set in the cylinder liner 1, and the two ends of cylinder liner 1 make spring 2,3 respectively, and the two ends of cylinder piston 4 are provided with commutation valve plate 5,6 respectively.The import of reciprocating pump is provided with two one-way valves 7,8, connects with bearing support 11 between the cylinder and piston pump, and the piston rod 12 of reciprocating pump is connected with cylinder piston 4.Axial pore 9,10 is set on the cylinder piston 4.Adopt the conical surface to add seal with elastometic washer between commutation valve plate 5 and the pore 9.The flat rubber sealing is set between commutation valve plate 6 and the pore 10.After pressurized air enters the A chamber of cylinder by suction port 14, promote commutation valve plate 6 and block pore 10, advance commutation valve plate 5,6 and cylinder piston 4 to move to an end of cylinder liner simultaneously, 5 pairs of pores 9 of commutation valve plate of this moment open wide, and the indoor gas of B is discharged through pore 9, air outlet 15.When commutation valve plate 5 roof pressures on the cylinder piston 4 during to spring 2, under the effect of spring, commutation valve plate 5 is blocked pore 9, push the commutation valve plate 6 of blocking pore 10 simultaneously open, make the pressurized gas of A chamber enter the B chamber rapidly, promote commutation valve plate 5,6 and cylinder piston 4 and move to the other end of cylinder liner, when commutation valve plate 6 roof pressures on the cylinder piston 4 during to spring 3, under the effect of spring 3, commutation valve plate 6 is blocked pore 10, pushes the commutation valve plate 5 of blocking pore 9 simultaneously open.Repeat above process, the to-and-fro motion that cylinder piston is gone round and begun again in cylinder liner, the piston that drives reciprocating pump moves back and forth, and reaches the function of inspiration, discharge by the one-way valve of reciprocating pump.
