Abstract
The utility model relates to an air compression system with constant-pressure air supply. The air compression system is characterized by comprising a motor (1), an air compressor (3) and an air storage tank (4), wherein a frequency converter (2) is mounted on the motor (1); the motor (1) is connected with the air compressor (3); an air outlet of the air compressor (3) is communicated with an air inlet of the air storage tank (4); a pressure sensor (5) is arranged in the air storage tank (4); the pressure sensor (5) is connected with a PID (Proportion Integration Differentiation) controller (6); the PID controller (6) is connected with the frequency converter (2) and a visual alarm (7); a pressure gage (8) is also mounted on the air storage tank (4). According to the air compression system with constant-pressure air supply, the speed of the frequency converter is controlled by the PID controller, the rotating speed of the motor is adjusted, the pressure of air which is input to the air storage tank by the air compressor is controlled, the power requirements of all kinds of equipment can be met, and the air supply stability is ensured.
Description
Technical field
The utility model relates to a kind of air compression system of constant pressure air feeding.
Background technique
In procedure of fibre production, in stoste workshop, conventionally adopt air-pressure equipment to provide pressed gas to equipment such as automatic filtering machines, for it provides power.But air-pressure equipment in the past is not equipped with constant-voltage equipment, cause the pressure surge of institute's supplied gas larger, can not meet the demand of various kinds of equipment, therefore bring impact to production.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of air feed stable, can meet various kinds of equipment demand, has guaranteed to produce the air compression system of the constant pressure air feeding normally carrying out.
The purpose of this utility model is achieved in that
The air compression system of the utility model constant pressure air feeding, comprise motor, air compressor and gas holder, on described motor, frequency variator is housed, described motor is connected with air compressor, the air outlet of air compressor is connected with the suction port of gas holder, in described gas holder, is provided with pressure transducer, and described pressure transducer is connected with PID controller, PID controller is connected with frequency variator for controlling the rotating speed of frequency variator, and pressure gauge is also housed on described gas holder.
On described PID controller, be also connected with visual alarm.
Compared with prior art, the beneficial effect that the air compression system of this constant pressure air feeding has is:
The air compression system of this constant pressure air feeding is by putting pressure transducer at built in gas tank, signal is passed to PID controller by this pressure transducer, PID controller is controlled the speed of the frequency variator of motor according to setting pressure, thereby motor speed is adjusted, control air compressor and throw the gas pressure in gas holder into, and then meet the power demand of various kinds of equipment, guarantee the stability of air feed.
On gas holder, pressure gauge is housed simultaneously, sees that to workman whether the gas pressure in gas holder is up to standard for convenient, in PID controller, warning circuit is housed simultaneously, can make alarm to pressure anomaly situation.
Accompanying drawing explanation
