How to do the high-pressure pump? Thank you very much. ﹏?

1. The manufacturing method of high-pressure air pump is as follows:

1 consists of three ordinary cylinders of different sizes. The gas is first compressed by the yellow piston and then enters the inner wall of the yellow piston tube, and then compressed by the white piston and then enters the inner wall of the white piston tube.

2. Then, it is compressed into the high-pressure air chamber at the bottom of the air pump by the smallest piston. There is a one-way valve in the high-pressure air chamber of the base, so the gas can't come out when it enters.

3. Then the high-pressure gas in the high-pressure air chamber enters the PCP cylinder through the air pipe. After the gas is exhausted, the exhaust valve of the air chamber should be unscrewed for decompression. The purpose of this is to close the valve of the quick connector on the car body first.

Second, the principle of high-pressure pump:

1. The same gas is compressed three times by three cylinders which decrease successively, thus producing high-pressure gas.

Extended data:

First, several types of pumps:

1, manual pumps are divided into two types:

(1), old-fashioned cowhide bowl pump with sliding inner tube (disadvantage: it is easy to stain clothes when pulled heavily).

(2) A new type of head pump with sliding outer tube (the advantage is that it is easy to pump and not easy to dirty clothes)

2. Pedal pumps are mainly divided into single tube and double tube.

3. The electric pump is driven by the power of the automobile cigarette lighter.

Second, the material of the pump: the strongest material is the inner and outer steel pipes connected without glue, followed by the aluminum alloy material connected with glue.

Third, the pump nozzle: There are mainly three kinds of nozzles on the market: 1 American special nozzle. The American mouth is connected with the English mouth. American, British and French type 3 general gas nozzles.

Four, pump base: mainly divided into three types, 1 is ordinary rubber, 2 is cast iron base, 3 is the latest glue-free base on the market, (the pump on the right is glue-free base).
