In the following, the application of the cylinder for the fluid transfer device will be described.
1. The inlet opening of the device connects to the water well through pipes, the outlet opening connects to the water tower. The piston 2 in the receiving chamber 1 moves upward to create a negative pressure area in the receiving chamber 1, under the effect of the atmosphere, the air in the pipe connected with the inlet opening goes into the second passage 8 through io the input passage 4, then goes into the first passage 7 through the manifold chamber, finally the air is pressed into the receiving chamber 1. Due to the downward movement of the piston 2 in the receiving chamber 1, the air in the receiving chamber 1 is pressed into manifold chamber through the first passage 7, then into the output passage 5 through the second passage 8, 15 finally into the water tower along the pipe connected with the outlet opening.
After the air in the pipe connected with the inlet opening is totally pressed out, the piston 2 in the receiving chamber 1 moves upward to create a 20 negative pressure area in the receiving chamber 1, under the effect of the atmosphere, water in the well is compressed into the receiving chamber 1 through the second and first passages 7, 8.
The downward movement of the piston 2 within the receiving chamber 1 25 compresses water therein out of the output passage 5 opening through the first and second passages 7, 8, due to the near incompressibility of water, the output passage 5 can output water flow with equal pressure, the water
11/15 flow at the outlet opening can climb a certain height along the pipe with the help of the pressure into the water tower. So the device can transfer water in a well with a certain depth to a water tower with a certain height, even there is some air left in the pipe connected with the inlet opening, the 5 device can still draw and pump water.
2. The inlet opening of the device connects with the atmosphere, the outlet opening connects with a gas tank through pipes. The piston 2 moves upward to create a negative pressure area in the receiving chamber 1, air near the io inlet opening is compressed into the receiving chamber 1 through the second and first passages 8, 7 by the effect of the atmosphere. The downward movement of the piston 2 within the receiving chamber 1 compresses air therein out of the output passage 5 opening through the first and second passages 7, 8, due to the compressibility of air, the output is passage 5 can output air flow with a little pressure, which is collected in the gas tank little by little, such that air mass with a certain pressure is finally formed in the tank, so the device can be used as an air compressor.
3. The inlet opening of the device connects with a sealing container, while 20 the outlet opening connects with the atmosphere, the piston 2 moves upward to create a negative pressure area in the receiving chamber 1, the air in the sealing container is compressed into the receiving chamber 1 through the second and first passage 8, 7 by the current air pressure in the container. The downward movement of the piston 2 within the receiving 25 chamber 1 compresses air therein out of the output passage 5 opening through the first and second passages 7, 8, and then into the atmosphere, so the device can draw air out of the sealing container to reduce air
12/15 pressure in the container. So the device can be used as an air-extractor.
