In the channel concentric cylinder cooling chamber 13 (when the concentric cylinder 14 is cooled), finally, after the water in the concentric cylinder cooling chamber 13 is filled, it flows out through the drain line 22 into the cooling water tank 23, and finally in the cooling fan 34. Under the action, the heat in the cooling water tank 23 will be released into the air; The two sides of the shaft 7 are provided with a concentric piston 8 and a low pressure piston 10 through a crank connecting rod. A high pressure piston push rod 9 is disposed at a center position of the upper end surface of the concentric piston 8, and the gas is sucked into the low pressure cylinder 27 through the low pressure upper cover 25. Then, it is compressed into the high pressure cylinder 21 through the copper gas pipe 28, and then the high pressure cylinder 21 compresses the gas, and finally the high pressure gas is output from the small gas outlet male 19, and the pressure of the high pressure gas is in the range of 0-100 MPa.

[0041] The specific implementation of the present invention: the high pressure piston push rod 9 is provided with a composite piston ring on the outer wall. Compared with the conventional cylinder compression mode, there is no need to lubricate and refuel during the friction process, and the lubricating oil vaporizes into the compressed air when the gas is compressed. The compressed air bottle is polluted, causing safety hazard when the person uses it. Similarly, the outer wall of the concentric piston 8 is provided with a composite wear ring, which is then slidably disposed in the concentric cylinder 14, and the outer wall of the low pressure piston 10 is provided with a composite The wear ring of the material is slidably disposed in the low pressure cylinder 27, because the high pressure cylinder 21, the concentric cylinder 14 and the low pressure cylinder 27 are all in the corresponding cooling chambers, which can effectively cool down, on the one hand, the piston ring and the wear ring are improved.

The cumulative number of work shows that the number of times the maintenance needs to be maintained, the air pump will prompt for maintenance; beyond the limit of the number of times, the air pump will protect itself and prevent the customer from opening; this function is because the upper ultra-high pressure has certain uncontrollable factors, in order to protect The safety of the customer's life.

[0046] Referring to Fig. 8, the rocking piston 116 is fixed on the upper side of the low-pressure connecting rod 105; the rocking wear ring 117 is disposed on the outer wall of the rocking piston 116; the rocking piston 116 is slidably disposed in the low-pressure cylinder 7-1; The low-pressure cylinder 7-1 is fixed on the motor casing 2 through the low-pressure upper cover 7-2 at the upper end; the low- pressure cylinder 7-1 and the low-pressure upper cover 7-2 together constitute a low-pressure assembly 7; The upper end of the upper cover 7-2 is provided with a low pressure cylinder sluice valve cover 7-2-1 and a filter muffler 111, and the left end of the low pressure upper cover 7-2 is connected to the copper gas pipe 108; the filter muffler 111 is advanced A low-pressure intake valve piece 118 is disposed at the air hole, and the low-pressure intake valve piece 118 is disposed. In order to prevent the gas from being discharged from the intake hole of the filter muffler 111 when the swing piston 116 ascends the compressed gas, the gas pressure is lost. A low-pressure air outlet valve piece 119 is disposed between the low-pressure cylinder valve cover bonnet 7-2-1 and the copper gas pipe 108, and the low-pressure air outlet valve piece 119 is disposed to avoid gas from the copper when the rocking piston 116 is lowered and inhaled. The high pressure cylinder 6-5 on the left side of the gas pipe 108 is recirculated, causing a loss of gas pressure.

[0047] The working principle of the invention: the motor shaft 103 drives the low-pressure connecting rod 105 to move upward, the high-pressure connecting rod 104 moves downward, the low-pressure intake valve piece 118 is closed, the low- pressure outlet valve piece 119 is opened, and the gas is swung by the rocking piston 116 through the low-pressure cylinder 7 -1 is fed into the low pressure cylinder valve cover 7-2-1, then enters the upper cover intake hole 6-2-1 through the copper gas pipe 108, and then enters the lower cover intake hole 6-3-1, and then Enter the intake duct 6-6-1, then enter the upper cover intake hole 6-4-1, then enter the upper cover transverse perforation 6-4-7, the high pressure cylinder intake check valve 6-7 opens, the gas enters the high pressure In the cylinder 6-5, the high pressure piston push rod 114 is driven downward by the concentric piston 112. The above steps complete the intake of the high pressure cylinder 6-5, and the low pressure cylinder 7-1 exhausts, that is, the entire gas path absorbs the gas. Then, the low-pressure connecting rod 105 moves downward, the low-pressure intake valve piece 118 is opened, the low-pressure outlet valve piece 119 is closed, and the gas is sucked from the filter muffler 111 into the low-pressure cylinder 7-1, and the high-pressure connecting rod 104 at this time During the upper movement, the high pressure piston push rod 114 moves upward and compresses the gas in the high pressure cylinder 6-5, and the high pressure cylinder outlet check valve 6-8 opens, and the compressed gas enters. Cover the transverse perforation 6-4-8, then enter the upper cover air vent 6-4-2, then enter the air guiding duct 6-6-3, because the air guiding duct 6-6-3 and the outlet duct 6-6-2 are In the same way, the compressed gas is finally discharged from the small air outlet 109; in this reciprocating cycle, the circulating compressed air of the air pump can be realized, and the pressure of the output high pressure gas ranges from 0 to 100 MPa.

[0048] In operation, the device that needs to be inflated is connected to the air outlet small male head 109 through a connecting pipe, and the numerical value display of the pressure temperature sensor 6-6-4 is observed during the process of collecting the gas, after the inflation operation is completed and the screwing is completed. Open the hand venting screw 110 to depressurize the entire air pump; the air pump can be set on the air pump, and the pressure and temperature signals sensed by the pressure temperature sensor 6-6-4 can be displayed on the LCD screen. Then, the air pump can realize the free set pressure, reach the set pressure and stop automatically; display the working temperature, working pressure, over temperature protection, overload protection, exceed the set allowable temperature, the machine stops automatically; exceed the set working current, the machine Self stop; single working time display; cumulative work times display, the number of work required to maintain maintenance, the air pump will prompt maintenance; beyond the limit of the number of work, the air pump will protect itself, not let customers open; this function is because of the upper high pressure There are certain uncontrollable factors in order to protect the safety of customers' lives.
