HOW DOES A HEYPAC "DOUBLE ACTING" PUMP WORK? (the technical stuff)
The Heypac pump works on a reciprocating differential area piston principle. This means that the pump uses a large area air drive piston connected to a smaller area hydraulic piston to convert compressed air power to hydraulic power. Great! What does that mean? The easiest way to explain it is with an example. The ratio between the air drive piston area and the hydraulic piston area is indicated by the pump model number.
GX40 means that this is a 40 : 1 pump so using this ratio, we can explain the principle of operation.
So, if you apply 4 BAR of air pressure to the air drive piston (60 times 15.6) you get 936 lbs. of force. Then you take the ratio, 40, times 4 BAR to the air drive, and that gives you 165 BAR. Now take the 165 BAR multiplied by the size of the hydraulic piston (0.39 sq. in.) and you get 936 lbs. of force. Therefore, the GX40 pump with an air drive pressure of 4 BAR will stall at 165 BAR because the forces equal out between the air drive piston and the hydraulic piston. Because of this method of operation the Heypac pump has the ability to stall at any predetermined pressure, and hold this pressure without consuming any power. The Heypac is run by compressed air, or other inert gas, so there is no danger of heat build up or fire from electrical sources, which means the Heypac can be used anywhere you can run an air line.
TECHNICAL DATA
| Maximum air consumption - | approx. 40 litres per sec. at 500 cycles per min. |
|
Maximum
air pressure - |
7 BAR |
|
Minimum
air pressure - |
1.4 BAR |
| Maximum cycle speed - | 500 cycles per min (intermittent duty). For continuous duty maximum cycle speed should be reduced to approx. 50 -60 cycles per minute. Applications involving continuous pumping should be referred to Heypac. |
