Abstract
The utility model discloses a high-pressure pump for a molecular sieve oxygen generator. The high-pressure pump for the molecular sieve oxygen generator comprises a high-pressure pump body, an air inlet pipeline, an air outlet pipeline, a high-pressure cavity and a compression device, wherein the air inlet pipeline and the air outlet pipeline are arranged on the high-pressure pump body, and the high-pressure cavity and the compression device are arranged in the high-pressure pump body. The high-pressure pump for the molecular sieve oxygen generator further comprises a decompression pipe, a decompression valve, a pressure sensor and a controller, wherein the decompression pipe is arranged on the high-pressure pump body, and is communicated with the compression device, the decompression valve is arranged in the decompression pipe, the pressure sensor is arranged in the high-pressure cavity, and the controller is arranged on the high-pressure pump body, and is connected with the pressure sensor. According to the high-pressure pump for the molecular sieve oxygen generator, due to the fact that the pressure sensor, the decompression pipe, the decompression valve and the controller are adopted, when the pressure sensor detects that the high-pressure pump body is in a high-pressure state for a long time, the decompression valve can be controlled by the controller to achieve the decompression function of the high-pressure pump, the potential safety hazard of the high-pressure pump is reduced, and the high-pressure pump cannot be easily damaged.
Description
Technical field
The utility model relates to a kind of pump, in particular, and particularly a kind of molecular-sieve oxygen generator high-pressure service pump.
Background technique
Along with the develop rapidly of medical science and technology, for increasing asthma patient and expiratory dyspnea symptom patient, the normal oxygenerator that adopts carries out assisted respiartion now.The working principle of common oxygenerator is: utilize molecular sieve physical absorption and desorption technique.In oxygenerator, load molecular sieve, and utilize it can be by airborne nitrogen adsorption in when pressurization, remaining unabsorbed oxygen be collected, and becomes highly purified oxygen after purified treatment.
For realizing the pressurization to oxygenerator, the high-pressure service pumps that adopt first compress air more now, again the air after compression is sent in the work gas circuit of oxygenerator and gone, but the shortcoming that existing high-pressure service pump exists is: high-pressure service pump is for a long time when high pressure conditions is worked, easily produce potential safety hazard and damage high-pressure service pump, therefore, need to improve for existing high-pressure service pump.
Model utility content
The purpose of this utility model is to have potential safety hazard and flimsy technical problem for high-pressure service pump of the prior art, and a kind of molecular-sieve oxygen generator high-pressure service pump is provided.
In order to solve problem set forth above, the technical solution adopted in the utility model is: molecular-sieve oxygen generator high-pressure service pump, comprise high-pressure service pump body, be located at admission line and outlet pipe on high-pressure service pump body, and be located at the intrinsic hyperbaric chamber of high-pressure service pump and compression set, also comprise and be located on high-pressure service pump body and the relief tube being communicated with compression set, be located at the Decompression valves in relief tube, be located at the pressure transducer in hyperbaric chamber, and the controller of being located at high-pressure service pump body and being connected with pressure transducer.
According to a preferred embodiment of the present utility model: also comprise and be located on high-pressure service pump body and the display unit being connected with pressure transducer.
According to a preferred embodiment of the present utility model: described controller is a MCU chip.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts pressure sensor, relief tube, Decompression valves and controller, when pressure transducer detects high-pressure service pump for a long time in a high pressure conditions, can control Decompression valves to realize the decompression function of high-pressure service pump by controller, reduced the potential safety hazard of high-pressure service pump, made high-pressure service pump not fragile.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but mode of execution of the present utility model is not limited to this.
Consult shown in Fig. 1, the utility model provides a kind of molecular-sieve oxygen generator high-pressure service pump, comprise high-pressure service pump body 20, be located at admission line 10 and outlet pipe 80 on high-pressure service pump body 20, and be located at hyperbaric chamber 30 and the compression set 90 in high-pressure service pump body 20, also comprise and be located on high-pressure service pump body 20 and the relief tube 40 being communicated with compression set 90, be located at the Decompression valves 50 in relief tube 40, be located at the pressure transducer 70 in hyperbaric chamber 30, and the controller (not shown) of being located at high-pressure service pump body 20 and being connected with pressure transducer 70.
The utility model is for the convenient monitoring function of realizing hyperbaric chamber 30 internal pressures, and it also can comprise is located on high-pressure service pump body 20 and the display unit 60 being connected with pressure transducer 70, and display unit 60 can show the pressure value of hyperbaric chamber 30 in real time.
Concrete, above-mentioned controller is a MCU chip.
Molecular-sieve oxygen generator of the present utility model by the working principle of high-pressure service pump is, the admission line 10 of high-pressure service pump is communicated with atmosphere, outlet pipe 80 is connected with the inlet end of molecular-sieve oxygen generator, during use, the compression set 90 of high-pressure service pump to high pressure (pressure value can be realized setting) state, and carries out oxygen by outlet pipe 80 output high-pressure gas by air compressing to the work gas circuit of molecular-sieve oxygen generator; And when high-pressure service pump is under a long working state, the air pressure of its generation likely surpasses prior setting value, now, pressure transducer 70 detects high pressure numerical value, can control the decompression function that Decompression valves 50 opens to realize high-pressure service pump by controller (not shown), reduced the potential safety hazard of high-pressure service pump, made high-pressure service pump not fragile.
