Abstract
A medical air compressor having adjustable output pressure and operating continuously comprises a medical oil-free compression pump, a high-pressure switch, a low-pressure switch, a relay and an electromagnetic valve, wherein the high-pressure switch and the low-pressure switch are connected with an air outlet of the medical oil-free compression pump respectively; a receiving end of the relay is connected with the high-pressure switch and the low-pressure switch; an output end of the relay is connected with the electromagnetic valve; and the electromagnetic valve is connected with the air outlet of the medical oil-free compression pump. The medical air compressor can be adjusted in output pressure range and operate continuously in any adjustment pressure range, thereby having a smaller size, lower noise and a longer service life.
Description
Technical field
The present invention relates to the adjustable and Medical air press of continuous service of medical compressor operation control field, particularly a kind of delivery pressure.
Background technique
Existing Medical air press mainly contains two kinds of operation control methods:
1) use frequency conversion compressor pump to make Medical air press keep outlet pressure and continuous service, substantially only have import brand Medical air press to take this operation control method, domesticly there is no suitable frequency conversion compressor pump production firm.During Medical air compressor operation, keep outlet pressure by the revolutions per minute increasing or reduce frequency conversion compressor pump and be compressor pump continuous service.This operation control method is expensive, controls complicated, domestic without providing business together.
2) using scope formula pressure switch controls the start and stop of compressor pump, when Medical air press outlet pressure reaches the high-voltage value of pressure switch, pressure switch controls compressor pump and quits work, when Medical air press outlet pressure drops to the low voltage value of pressure switch, pressure switch controls compressor pump and restarts work.This operation control method can impact compressor pump; affecting the working life of compressor pump, in order to strengthen the start and stop interval time of compressor pump, needing configuration jumbo gas holder; the volume of Medical air press is increased, and the start and stop of compressor pump also can cause influence of noise.
Summary of the invention
The object of the present invention is to provide a kind of delivery pressure adjustable and the Medical air press of continuous service, adjustable medical air compressor delivery pressure scope, and arbitrarily regulating continuous service in pressure range, make that Medical air press volume is less, noise is lower, the life-span is longer.
For solving the problems of the technologies described above, the present invention includes: medical without oily compressor pump, high-pressure switch, low pressure switch, relay and solenoid valve, wherein: high-pressure switch, low pressure switch are connected with the medical air outlet without oily compressor pump respectively, the receiving terminal of relay is connected with high-pressure switch, low pressure switch, output terminal is connected with solenoid valve, and solenoid valve is connected with the medical air outlet without oily compressor pump.
The high pressure of described high-pressure switch refers to: solenoid valve cracking pressure, and the low pressure of low pressure switch refers to: closed electromagnetic valve pressure.
Described high-pressure switch is connected without oily compressor pump with medical by tee union with low pressure switch.
Described relay adopts electromagnetic form.
Described solenoid valve is the two-bit triplet solenoid valve of normally off.
Beneficial effect
Compressor pump of the present invention continuous firing in range of working pressure, does not affect by start/stop impact, extends the working life of compressor pump; High pressure and low pressure are monitored separately by high-pressure switch and low pressure switch respectively, and monitoring pressure is adjustable, applied widely; Medical without oily compressor pump continuous service, without start/stop impact, without the need to Large Copacity gas holder, Medical air press volume can be reduced; Medically without start-stop, be conducive to Noise measarement without oily compressor pump continuous service, reduce noise.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is structural drawing of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As depicted in figs. 1 and 2, the present embodiment comprises: medical without oily compressor pump 1, high-pressure switch 2, low pressure switch 3, relay 4 and solenoid valve 5, wherein: high-pressure switch 2, low pressure switch 3 are connected with the medical air outlet without oily compressor pump 1 respectively, the receiving terminal of relay 4 is connected with high-pressure switch 2, low pressure switch 3, output terminal is connected with solenoid valve 5, and solenoid valve 5 is connected with the medical air outlet without oily compressor pump 1.
The high pressure of described high-pressure switch 2 refers to: solenoid valve 5 cracking pressure, and the low pressure of low pressure switch 3 refers to: solenoid valve 5 closing pressure.
Described high-pressure switch 2 is connected without oily compressor pump 1 with medical by tee union with low pressure switch 3.
Described relay 4 adopts electromagnetic form.
Described solenoid valve 5 is two-bit triplet solenoid valve 5.
Described solenoid valve 5 is normally off.
During enforcement, medically to bring into operation without oily compressor pump 1, because solenoid valve 5 is in normally off, now air compressor air outlet pressure durations raises, when air compressor air outlet pressure reaches high-pressure switch 2 monitoring pressure, high-pressure switch 2 outputs signal to relay 4, relay 4 Controlling solenoid valve 5 is opened, air compressor air outlet pressure is reduced, when air compressor air outlet Pressure Drop is to low pressure switch 3 monitoring pressure, low pressure switch 3 outputs signal to relay 4, relay 4 Controlling solenoid valve 5 is closed, air compressor air outlet pressure is raised until reach high-pressure switch 2 monitoring pressure, and so forth Medical air press air outlet Stress control setting low pressure switch monitors pressure and high-pressure switch monitoring pressure between.
Below the preferred embodiment of the invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modifications or replacement are all included in the application's claim limited range.
