[0066] Experiment II, as shown in the following figure: Figure 3 ​​

[0067] Experiment II contains the following components: recovery box 6, 1.8kw portable high pressure cleaner 9, power switch 8, ammeter 4, 15kg pressure relief valve 5, wherein the same number of components are common parts in experiment I.

[0068] Experiment II is initially: the amount of water in the recovery box 6 is the amount of water discharged from the A tank in experiment I, and the ammeter 4 is reset to zero.

[0069] Experiment II begins: turn on the power switch 8, when the water in the recovery basin 6 is just pumped out, immediately turn off the power switch 8, and then record the power consumption of the ammeter 4.

[0070] As Figure 4 shown, according to the work curve of the compressor and the cleaner, we know that in experiment II, the cleaner is always working at 16kg pressure, while in experiment I, when the compressor is working, the air pressure in tank B helps to push the piston, reducing the work of the motor on the piston. Because the air in tank B is gradually discharged, the air pressure in tank B gradually decreases, and at the same time the work of the compressor also gradually increases, they are inversely proportional, so the work curve of the compressor is a straight line. It is equivalent to the air pressure in tank B helping the motor to reduce half of the work, and finally achieving the purpose of saving energy.

[0071] As Figure 5 shown, according to the statistical table, experiment I and experiment II do the same amount of work, but the power consumption is different, experiment I only uses 0.03 degrees of electricity, experiment II uses 0.06 degrees of electricity, which is equivalent to saving more than half of the energy. Therefore, the above experimental results can prove that the technical scheme of the present application is more energy-saving.

[0072] Experiment III, as Figure 6 shown:

[0073] Experiment III contains the following components: AB tank, cylinder 3 (3# workpiece is modified from SC32X350-S cylinder, that is, a valve plate is added at the bottom to facilitate manual simulation of the internal work of the compressor. Actually, experiment III and experiment I have the same working process, the difference is that experiment I uses electricity as power, while experiment III provides power manually.

[0074] Experiment III initially: A tank is filled with water, B tank is filled with 5kg of compressed air, the discharge pressure of the pressure relief valve 5 is adjusted to 5kg, and the recovery basin 6 is empty to receive all the water discharged from the A tank.

Assume that the total amount of water in the A tank is unit 1

[0075] Experiment III begins; the recovery basin 6 collects the water discharged from tank A and passing through the pressure relief valve 5, then switches 1 and 2 are turned on, and the cylinder handle is manually grasped to perform manual work on cylinder 3. When the water in tank A is just drained, the manual work is stopped.

[0076] Experiment IV, such as Figure 7 As shown:

[0077] Experiment IV includes the following components: cylinder 3 [Workpiece 3 is a modified SC32X350-S cylinder, with a valve plate added to the bottom to facilitate manual simulation of the internal workings of a cleaning machine. Experiment IV and Experiment II have the same workflow; the difference is that Experiment II uses electricity, while Experiment IV is manually powered], pressure relief valve 5, and recovery basin 6. Components with the same serial number are shared components from Experiment III.

[0078] The initial state of Experiment IV was that the water in the recovery basin 6 was the total amount of water discharged from tank A in Experiment III.

[0079] Experiment IV begins; a person manually grasps the handle of the cylinder and performs manual work on cylinder 3. When the water in the recovery basin 6 is just completely sucked up, the manual work is stopped.

[0080] The result of experiment IV is that, because the high-pressure gas in tank B assists the piston in the cylinder to do work in experiment III, experiment III requires less effort.

[0081] Through the above experiments, we can obtain the technical effect of this application: high-pressure gas can reduce the operating energy consumption of air compression devices, thereby achieving the effect of reducing energy consumption, which has the advantages of energy saving and environmental protection. Therefore, the technical solution of this application can solve the technical problem of reducing energy consumption.
