Problems solved by technology
[0004] 1. The capacity of the cooling water tank is limited and can only hold a certain amount of water. The cooling effect is good at the initial stage of operation. As the water continues to absorb heat, the water temperature rises. When the water temperature is almost the same as the surface temperature of the pipeline, the water cannot function cooling effect
[0005] 2. The water-cooled pump is greatly affected by the ambient temperature. If the ambient temperature is lower than zero, the water will freeze; if the ambient temperature is too high, the water will not be able to cool down.
[0006] 3. Since the water tank is filled with water, water will overflow when the environment is shaken or tilted. The water-cooled pump must be installed stably and not tilted. It cannot be installed on a car or boat.

Embodiment Construction
[0013] Such as figure 1 , figure 2 As shown, the present invention uses a motor-driven fan as a cooling air source. The fan blade 3 is riveted on the impeller 4 with a rivet 5, and the impeller 4 is mounted on the motor shaft 18. The air pipe 2 is coiled into a helical shape, fixed by the support frame 18 and coiled around the fan blades. Radiating fin 1 is a thin metal sheet, and is processed into a helical shape and is enclosed within the air pipe 2, so that the cooling effect is better. Support frame 18 is to be fixed on the support 7 with set screw 6, and motor 14 is also fixed on the support 7 with screw 19. From figure 1 , figure 2 It can be seen from the figure that the motor 14 is not only used as the motor of the cooling air source, but also can transmit power to the pump body 11 as the driving motor of the pump body 11 through the pulley set. 9 is a belt, and 17 is that the motor belt pulley is contained on the motor shaft 8, and the large belt pulley 10 is c...

The invention belongs to the technical field of inflator pump, and concretely relates to air cooling equipment for a small-sized oxygen filling pump. The air cooling equipment adopts a fan driven by a motor as a cooling air source, and an air pipe is fixed and wound around blades of the fan. Thus, the motor can drive the blades of the fan to rotate and generate a large air flow, and then lowers the temperature of the air pipe wound around the blades of the fan and consequently lowers the temperature of air flowing in the air pipe. In order to achieve a better air cooling effect, spiral cooling blades can be wound on the pipe wound around the blades of the fan. The air cooling equipment has the advantages of simple structure and reasonable design. In addition, the oxygen filling pump provided with the cooling equipment can not be limited by the use environment and transportation condition, and has a wide application range and reliability during use.
Description
1. Technical field [0001] The invention belongs to the technical field of air pumps. It specifically relates to an air cooling device for a small oxygenation pump. 2. Background technology [0002] Small oxygen pumps are mainly used in mines, firefighting, troops, ships, aviation, medical and other departments. Use this device to fill small oxygen cylinders with high pressure oxygen, such as oxygen respirators, small oxygen infusers, etc. The equipment can also be used for filling nitrogen, helium, carbon dioxide, air and other gases. [0003] Since the temperature of the gas will increase during the process of being compressed and boosted, it is necessary for the oxygen pump to cool the gas during the filling process. The oxygen pump that uses at present adopts water-cooling mode to the cooling of gas, is that the gas pipeline is hovered in the cooling water tank that 8 liters of water are housed, relies on water to cool the gas in the gas pipeline. There are many defic...
