Abstract
The utility model discloses an oxygen filling pump which comprises a box. A compressor and a motor are arranged inside the box. An air inlet nozzle and an inflation nozzle are arranged on an outer panel of the box. The air inlet nozzle is communicated with the compressor, and the inflation nozzle is communicated with the compressor through a gas cooling tank. The motor drives the compressor to work. An oil-free compressor technology is adopted in the oxygen filling pump, and filling pressure can be controlled automatically. Oxygen is extracted from an air source bottle, pressurized and filled into a filled bottle. The oxygen filling pump is mainly used in filling an oxygen breathing device and a compressed oxygen self-rescuer. The oxygen filling pump has the advantages of being reasonable in structural design, convenient to use and maintain, and the like.
Description
Technical field
The utility model relates to a kind of oxygen pump.
Background technique
Oxygen pump is mainly used in the gas boosting pump of filling oxygen resuscitation apparatus and compressed oxygen self-lifesaving device high-pressure gas cylinder.It is the oxygen in the large air cylinder or other non-ignitibility gas to be boosted be filled in another air cylinder, can automatically control stowing pressure, is widely used in the place that colliery, medical treatment, fire-fighting, aviation, petrochemical industry, metallurgy, boats and ships etc. use gases.Existing oxygen pump complex structure, use and maintenance is inconvenient.
Summary of the invention
For defective or the deficiency of prior art, the purpose of this utility model is to provide a kind of oxygen pump of simple in structure, easy maintenance.
For realizing above-mentioned technical assignment, the utility model is taked following technical solution:
A kind of oxygen pump comprises casing, it is characterized in that, compressor and motor are installed in the casing, are provided with air inlet nozzle and charging air inlet on the casing outer panels, described motor-driven compressor work, described air inlet nozzle communicates with compressor, and described charging air inlet communicates with compressor by the gas cooling case.

Described air inlet nozzle place is equipped with air-intaking adjusting valve.
Described charging air inlet place is equipped with the inflation by-pass cock.
Oxygen pump of the present utility model adopts the oilless compressor technology, can automatically control stowing pressure, oxygen is extracted out to be filled to after the supercharging from gas source bottle filled in the bottle.It is mainly used in filling oxygen resuscitation apparatus and compressed oxygen self-lifesaving device, has reasonable in design, and working service is characteristics easily.
Description of drawings
Fig. 1 is the front view of box inner structure of the present utility model;
Fig. 2 is the plan view of box inner structure of the present utility model.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
Embodiment
With reference to figure 1 and Fig. 2, according to the technical solution of the utility model, this embodiment's oxygen pump comprises casing 5, two stage compressor 1 and motor 2 are installed in the casing 5, be provided with one-level cylinder and secondary cylinder in the two stage compressor 1, compressed gas in the one-level cylinder enters secondary cylinder through gas cooling case 3, be provided with air inlet nozzle and charging air inlet 4 on casing 5 outer panels, the air inlet nozzle place is equipped with air-intaking adjusting valve, the charging air inlet place is equipped with the inflation by-pass cock, motor 2 drives two stage compressor 1 work, described air inlet nozzle communicates with the one-level cylinder, described charging air inlet 4 communicates with secondary cylinder by gas cooling case 3, is provided with the bleed pressure table on the outer panels of casing 5, one-level cylinder pressure gage and secondary cylinder pressure gauge.
The complete machine working principle is to finish the oxygen filling work for the treatment of gas filling bottle by constantly to-and-fro motion of the plunger on the two stage compressor 1, when the plunger in the one-level cylinder of two stage compressor 1 moves downward, gas in the one-level cylinder expands thereupon, pressure decreased, in the pressure in the one-level cylinder is lower than large oxygen cylinder during the pressure of gas, the one-level Aspirating valves is opened automatically, and gas is flowed in the one-level cylinder by gas source bottle; When the one-level plunger moved upward, gas was compressed in the cylinder, and pressure raises, when its pressure greater than secondary cylinder in during gas pressure, the outlet valve of one-level cylinder and the Aspirating valves of secondary cylinder are all opened, gas just flows in the secondary cylinder in the one-level cylinder; When the secondary cylinder inner plunger moves upward, gas in the secondary cylinder is compressed, pressure raises, when its pressure greater than being inflated in the bottle during gas pressure, flow into by the one-way valve on the moisture trap, gas-filled switching tube through secondary exhaust valve and to be inflated in the bottle, namely finish once inflation, all need to cool through gas cooling case 3 through the gas of one-level cylinder and secondary cylinder compression.
