Abstract
Description
Technical Field
[0001] The utility model relates to the field of air compression pumps, in particular to a low-vibration plateau type oil-free air compression pump. Background Art
[0002] The oxygen in the air in plateau areas is thin, and there is a great demand for oxygen concentrators. Compared with oxygen cylinders, the use of oxygen concentrators is sustainable, without the need to carry a large number of oxygen cylinders, and also reduces the pollution caused by discarding oxygen cylinders.
[0003] The oxygen concentrator cannot work without an air compressor. In order to avoid the pollution of the air by lubricating oil, most micro oxygen concentrators use oil-free air compressors, which compress the air by the piston movement in the oil-free air compressor. In order to reduce vibration, a leather cup can be installed on the piston, and the leather cup can be used to slide in contact with the inner wall of the cylinder sleeve. However, when the piston moves at high speed, the friction between the leather cup and the cylinder sleeve generates a lot of heat, which cannot be dissipated in time, resulting in an increase in the overall temperature, which reduces the service life of the leather cup and the cylinder sleeve, and needs to be improved.
