Air rifle pumps are made with different racks. Pushers in devices are installed in vertical and horizontal position. Filters are most often used with expanders. For safe use of the model there are sealing sleeves.
The pressure limit parameter depends on the quality of the valves. If we consider modifications with horizontal uprights, then they have an adapter with a spring. In order to more thoroughly understand this issue, you should consider the device of a standard pump.
Device and principle of operation
A typical model (drawings of a high-pressure pump for pneumatics shown below) includes a round stand, a handle and a rod. Also in the devices there is a plunger mechanism. The principle of operation of a high-pressure pump for pneumatics is based on increasing the pressure inside the chamber. This happens due to the movement of the pushers. They are located under the filter.
Adapters are used to stabilize the pressure in the chamber. There is a special rod in the pump rack. On some models, the plunger mechanism includes a landing pin. When the handle is lifted, it is lowered. When the pushers begin to move, the fitting goes down. Pressure limit is fixed by a manometer.
Homemade modification
How to make a high pressure pump for pneumatics? First of all, it is important to note that it is easier to make a model with a horizontal stand. To assemble a high-pressure pump for pneumatics with your own hands, first of all, a cylindrical body is taken. The handle under it should be selected a small width. Directly the bar is connected to the adapter. The upper valve of the pump is fixed above the fitting.
A jumper is used to connect the spring. The first sealing sleeve is installed at the top of the rack. Next, to assemble a high-pressure pump for pneumatics with your own hands, you will need a second valve. To fix it, you will have to use a blowtorch. In this case, the fitting is important to be well lubricated with machine oil. Lastly, foot rests are installed. The pressure gauge for a home-made high-pressure pump for pneumatics is most often fixed near the jumper.
Choosing a quality model
How to choose a high pressure pump for pneumatics? First of all, it is important to consider the maximum power parameter. The threshold overload indicator, as a rule, does not exceed 4 microns. The adapter must be made of aluminum. The diameter of the return spring is about 3.6 cm.
Good models use two sealing sleeves. The top valve must be fixed firmly. Separately, when buying a device, the foot stop is checked. In some cases, it is done with side pads. The handle should be held firmly in hands and not hang around. There is a quality model in our time about 16 thousand rubles.
Pump crosman
