The utility model discloses adjustable medical air compressor machine output pressure range to last the operation at arbitrary adjust pressure within range, make that medical air compressor machine volume is littleer, the noise is lower, the life -span is longer.
Description
Technical field
This utility model relates to medical compressor operation control field, and particularly a kind of output pressure is adjustable
And the Medical air press of continuous service.
Background technology
Existing Medical air press mainly has two kinds of operation control methods:
1) frequency conversion compressor pump is used to make Medical air press keep outlet pressure continuous service, substantially only
There is import brand Medical air press to take this operation control method, domestic there is no suitable frequency conversion compression
Pump production firm.During Medical air compressor operation, by the revolutions per minute of frequency conversion compressor pump is increased or decreased
Keep outlet pressure and be compressor pump continuous service.This operation control method is expensive, controls
Complexity, domestic without providing business together.
2) range formula pressure switch controls the start and stop of compressor pump, when Medical air press outlet pressure
When reaching the high-voltage value of pressure switch, pressure switch controls compressor pump and quits work, when Medical air press
When outlet pressure drops to the low voltage value of pressure switch, pressure switch controls compressor pump and restarts work.
Compressor pump can be impacted by this operation control method, affects the service life of compressor pump, in order to add
The start and stop interval time of big compressor pump, need to configure a jumbo air accumulator, make Medical air press
Volume increase, the start and stop of compressor pump also can cause influence of noise.
Utility model content
The purpose of this utility model is to provide a kind of output pressure adjustable and the medical pneumatics of continuous service
Machine, adjustable medical air compressor machine output pressure scope, and continuous service in arbitrarily regulation pressure limit,
Make that Medical air press volume is less, noise is lower, the life-span is longer.
For solving above-mentioned technical problem, this utility model includes: medical oil free compression pump, high-pressure
Switch, low pressure switch, relay and electromagnetic valve, wherein: high-pressure switch, low pressure
Switch gas outlet with medical oil free compression pump respectively is connected, and the receiving terminal of relay is opened with high-pressure
Close, low pressure switch is connected, and outfan is connected with electromagnetic valve, electromagnetic valve and medical oil free compression pump
Gas outlet be connected.
The high pressure of described high-pressure switch refers to: electromagnetism valve opening pressure, low pressure switch
Low pressure refers to: closed electromagnetic valve pressure.
Described high-pressure switch and low pressure switch by three way cock and medical oil free compression pump phase
Even.
Described relay uses electromagnetic form.
Described electromagnetic valve is the two-bit triplet electromagnetic valve of normally off.
Beneficial effect
This utility model compressor pump continuous firing in working pressure range, is not affected by start/stop impact,
Extend the service life of compressor pump；High pressure and low pressure are switched by high-pressure switch and low pressure respectively
It is separately monitored, and monitors pressure adjustable, applied widely；Medical oil free compression pump continuous service,
Without start/stop impact, it is not necessary to Large Copacity air accumulator, Medical air press volume can be reduced；Medical oil free compression
Pump continuous service, without start-stop, the most noise control, reduce noise.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model；
Fig. 2 is structure chart of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As depicted in figs. 1 and 2, the present embodiment includes: medical oil free compression pump 1, high-pressure switch
2, low pressure switch 3, relay 4 and electromagnetic valve 5, wherein: high-pressure switch 2, low pressure pressure
Power switch 3 gas outlet with medical oil free compression pump 1 respectively is connected, the receiving terminal of relay 4 and height
Pressure pressure switch 2, low pressure switch 3 are connected, and outfan is connected with electromagnetic valve 5, electromagnetic valve 5
It is connected with the gas outlet of medical oil free compression pump 1.
The high pressure of described high-pressure switch 2 refers to: pressure opened by electromagnetic valve 5, and low pressure is opened
The low pressure of pass 3 refers to: electromagnetic valve 5 closing presure.
Described high-pressure switch 2 and low pressure switch 3 are by three way cock and medical oil free compression
Pump 1 is connected.
Described relay 4 uses electromagnetic form.
Described electromagnetic valve 5 is two-bit triplet electromagnetic valve 5.
Described electromagnetic valve 5 is normally off.
During enforcement, medical oil free compression pump 1 brings into operation, because electromagnetic valve 5 is in normally off, this
Time air compressor machine gas outlet pressure persistently raise, when air compressor machine gas outlet, pressure reaches high-pressure switch 2
During monitoring pressure, high-pressure switch 2 outputs signal to relay 4, and relay 4 controls electromagnetic valve 5
Open, make air compressor machine gas outlet pressure reduce, when air compressor machine gas outlet pressure is down to low pressure switch 3
During monitoring pressure, low pressure switch 3 outputs signal to relay 4, and relay 4 controls electromagnetic valve 5
Closing, making air compressor machine gas outlet pressure raise until reaching high-pressure switch 2 to monitor pressure, so
Back and forth Medical air press gas outlet Stress control at the low pressure switch monitors pressure set and high pressure
Between pressure switch monitoring pressure.
Below the preferred embodiment created this utility model is illustrated, but this practicality is new
Type is created and is not limited to described embodiment, and those of ordinary skill in the art are new without prejudice to this practicality
Modification or the replacement of all equivalents, these equivalent modifications can also be made on the premise of type creative spirit
Or replacement is all contained in the application claim limited range.
