Air respirator filling pump with cylinder body being provided with cooling device

Abstract

The invention relates to an air respirator filling pump with a cylinder body being provided with a cooling device, which comprises a compressor device, a driving motor and a stand, wherein the compressor device comprises a multilevel compressed air cylinder, wherein a cylinder body of the compressed air cylinder is provided with a hollow guide groove. The wall of the cylinder body of the compressed air cylinder of each level is provided with the guide groove, so when in use, coolant flows through the guide groove, and the compressor device can be effectively cooled. The coolant can radiate the heat through the circulating flow inside the guide groove via a pump, a water box and a cooling box, and the heat radiation also can be realized by utilizing external tap water or water source with a given pressure to flow inside the guide groove. The cylinder body is provided with the guide groove, so the cooling effect of the compressor device is greatly improved, the long-term continuous work can be realized, the running service life and the reliability can be greatly improved, and the temperature of the output gas can be reduced. The air respirator filling pump can be widely applicable to the fields such as military, chemical engineering, ships, petroleum, smelting, warehouse, high-voltage test, enterprise, mines and the like.

Description

technology field; [0001] The invention relates to an air respirator filling pump. Background technique; [0002] Due to the widespread application of high-pressure implementation, the original high-pressure filling equipment technology has been unable to meet people's needs. The air filling pump is a kind of gas collection and compression equipment, which is widely used in the fields of air breathing apparatus filling for firefighters, military, aerospace, shipbuilding, petroleum, chemical industry, pipeline inspection, pressurization test, etc., for example: there is no high-pressure filling pump All air respirators in the world will not be able to continue to be used effectively, and the pipeline pressure detection in China's West-East Gas Pipeline Project will also not be completed. The compressed gas for astronauts to breathe on Shenzhou 7 is also realized through high-pressure filling pumps. . Due to the particularity of this product, the performance requirements of i...

Problems solved by technology

[0004] However, such products produced and used at home and abroad cannot guarantee the requirements of continuous and uninterrupted work. Due to the design defects of the compression cylinder, this greatly increases the production cost and restricts the rapid development of this field.

If the existing technical equipment of this type needs to be continuously used in some special occasions, it will not be able to be completed. If the continuous use will cause the compression cylinder of the filling pump to be seriously damaged and scrapped due to the lack of effective and sufficient heat dissipation of the compression cylinder, it will be rejected. Serious suspension of work will endanger personal safety

Since the cooling methods are mainly fans, radiators and other devices, it is well known that the high-pressure filling pump uses mechanical principles to compress the volume of the gas to a certain proportion for use. The principle of friction generates a lot of heat, and the gas can quickly heat up after being compressed. Due to the principle of thermal expansion and cold contraction, the gas increases and the friction force increases, so that the equipment cannot play the best effect, because the accumulation of heat cannot be effectively and fully The release makes the machinery unable to work continuously and normally, causing the air respirator filling pump to fail to work normally, and the reliability is poor

In addition, due to the high heat of the cylinder, it will not be cooled immediately, which will cause the temperature of the compressed gas to be high, and it cannot be used immediately
