Abstract
The utility model relates to a pressurizing type pneumatic plunger pump. The utility model is characterized in that a pressurizing piston is arranged on an output link rod of an existing ordinary pneumatic plunger pump, and the other end of the pressurizing piston is connected with a plunger. When the utility model works, the pressurizing piston, the link rod and the plunger move repeatedly in a barrel body together, a pneumatic end and a pump end are connected into a whole through the barrel body, and the structure of the other parts of the pump is identical to the structure of the existing pneumatic plunger pumps. The output pressure of the utility model can be higher than the air supply pressures of a pneumatic mechanism of the pump, and the utility model enlarges use ranges of pneumatic pumps.
Description
The utility model relates to a kind of air piston pump, particularly a kind of supercharging type air piston pump.
At present, existing pneumatic pump as membrane pump with pneumatic drive, all belongs to direct acting type, and the delivery pressure of pump can only be equal to or less than the supply gas pressure of pneumatic mechanism.When needs increase the delivery pressure of pump, can only change the supply gas pressure of source of the gas, it is very inconvenient to use, and has limited the using scope of pump.
The purpose of this utility model is at the prior art above shortcomings, and a kind of supercharging type air piston pump is provided, and utilizes the utility model, does not need to change the pressure of source of the gas, can reach the purpose that increases delivery pressure, and is easy to use.
The purpose of this utility model is achieved in that a kind of supercharging type air piston pump: comprise piston cylinder, the reciprocating output link rod of pneumatic mechanism, plunger, the two ends that it is characterized in that this plunger pump output link rod are equipped with charged piston, the other end and the plunger of charged piston link, and above-mentioned charged piston is reciprocating with output link rod, plunger in piston cylinder.The structure of the remaining part of pneumatic mechanism of the present utility model and pump is identical with existing air piston pump.
Supercharging principle of the present utility model is such: the diameter of establishing charged piston is D, and the diameter of plunger is d, and supply gas pressure is P
0, the delivery pressure of pump is P, the pressure balance relation is:
When D=d, P=P
0, and as long as D>during d, P>P is arranged then
0, promptly select different diameters than D/d, just can reach the purpose that the delivery pressure that makes pneumatic pump is higher than supply gas pressure, very simple, convenient.
The same with existing air piston pump, the utility model can be single, also can be double-acting.
The utility model compared with prior art has the following advantages: 1. as long as select the diameter of suitable charged piston and the diameter of plunger, can reach the purpose that increases delivery pressure, and not need to change supply gas pressure; 2. because the utility model has just been installed charged piston on the output link rod, therefore simple in structure, easy to manufacture; 3. the utility model is easy to use, and pressurized effect is reliable, has enlarged the using scope of air piston pump.
Below in conjunction with accompanying drawing, the utility model is described in detail in detail with most preferred embodiment of the present utility model.
Fig. 1 is the structural representation of double-acting type supercharging type air piston pump.
As shown in Figure 1, reciprocal output link rod 1 at the air piston pump pneumatic mechanism is installed a charged piston 5, these charged piston 5 usefulness snap rings 4, pressing plate 3 usefulness screws 2 are fixed on the two ends of link rod 1, the other end of charged piston 5 links to each other with plunger 8 with screw 7, during work, charged piston 5 is reciprocating in cylinder body 6, and cylinder body 6 joins pneumatic end and pump end together, and the structure of the other parts of pneumatic end of the present utility model, pump end and pump is all identical with existing air piston pump.
Claims (2)
