Gas can be divided into pneumatic gas booster pump and pneumatic liquid booster pump booster pump, they have many similarities, but there are also some differences, such as one-way valve structure are not the same, the compressibility of gas and liquid, and gas booster cylinder piston liquid booster pump plunger used.
The gas booster pump only discusses the pneumatic gas booster pump. The theoretical supercharging ratio is the piston area of the driving cylinder S1: the piston area of the booster cylinder is S2, the actual supercharging ratio can reach 40:1, but 10:1 or less compression ratio is recommended in the industrial application.
Control valve V1 and V2, reversing valve V3. The right side of the V3 is connected to the underside of the V2. When the pressure at the right side of the V3 is 0, the V3 valve at the left end of the compressed air P drives down to the right end. At this time, the compressed air on the upper side of the driving cylinder is connected, and the lower side is connected with the atmosphere, and the large piston is forced downward.
Although the left and right sides of the V3 valve core are connected with compressed air, the V3 valve is sliding to the left end because the force area at the right end is greater than the force area at the left end. Because at this time the drive cylinder at the lower side of the compressed air, the upper side of the atmosphere connected, so the piston upward movement. Then, the large piston touches the control valve V1, the pipe 1 is deflated to 0, so that the right side of the V3 pressure is 0, so as to achieve a cycle of movement.
