Abstract
The invention discloses a constant flow control system of an aircraft air supply cart. The constant flow control system of the aircraft air supply cart comprises a balance type supply gas pressure control system, a compressor, an engine and a flow meter. The constant flow control system of the aircraft air supply cart comprises a supply gas pressure balance valve, an air adjusting solenoid valve and an air transmission ball valve. The supply gas pressure balance valve is provided with a pressure signal feedback tube. As the balance type supply gas pressure control system is adopted to control pressure, when the flow meter detects that compressed air flow is higher than or lower than set flow, an ECU of the engine will increase or decrease the rotation speed of the engine, the rotation speed of the compressor is controlled, and accordingly air supply flow can be constant. The constant flow control system of the aircraft air supply cart is simple in structure, high in accuracy of automatic control and high in sensitivity.
Description
Technical field
The present invention is a kind of gas Flowrate Control System, particularly can, according to airspeed, automatically regulate, and makes air demand reach the control system of constant flow rate.
Background technique
The Flow-rate adjustment of the air feed that aircraft air source truck uses is at present an artificial fixed value that regulates or set according to experience in the time that equipment is installed, and makes to reach constant into gas supply flow as far as possible.Can not be according to the change of environmental conditions in the time that air demand changes and automatic constant gas supply flow, as kept constant gas supply flow to need artificially debugging again to set.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the constant flux control system of aircraft air source truck.
The technological scheme solving the problems of the technologies described above is: a kind of constant flux control system of aircraft air source truck, comprise balanced type supply gas pressure control system, compressor, motor and tachometer, balanced type supply gas pressure control system comprises supply gas pressure equilibrium valve, air conditioning solenoid valve and air conveying ball valve; Described supply gas pressure equilibrium valve is provided with pressure signal feedback pipe.Described tachometer is electrically connected with described motor.
The present invention is owing to having adopted balanced type supply gas pressure control system pilot pressure, in the time that tachometer detects compressed air require higher or lower than setting flow, the ECU of motor will heighten or reduce the rotating speed of motor, the rotating speed of compressor is realized and being controlled, thereby realize the constant of gas supply flow.The present invention is simple in structure, and control accuracy is high, highly sensitive automatically.
Accompanying drawing explanation
Fig. 1 is the structural representation of the constant flux control system of aircraft air source truck.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
As shown in Figure 1, a kind of constant flux control system of aircraft air source truck, comprise balanced type supply gas pressure control system, compressor 1, motor 2 and tachometer 3, balanced type supply gas pressure control system comprises supply gas pressure equilibrium valve 4, air conditioning solenoid valve 5 and air conveying ball valve 6; Described supply gas pressure equilibrium valve 4 is provided with pressure signal feedback pipe 7.
The working principle of the constant flux control system of above-mentioned aircraft air source truck is: when compressor 1 is started working, the pressure that balanced type supply gas pressure control system control air is carried, in the time that tachometer 3 detects compressed air require higher or lower than setting flow, tachometer 3 can send to the data that detect the ECU of motor 2, the ECU of motor 2 will heighten or reduce the rotating speed of motor 2, the rotating speed of compressor 1 is realized and being controlled, thereby realize the constant of gas supply flow.
