Description
Technical field
The present invention relates to middle-high pressure air compressor, particularly relate to a kind of screw piston composite middle-high pressure air compressor.
Background technique
Air compressor is the main body in compressed air source unit, and it is the device mechanical energy of prime mover being converted to gas pressure energy, is compressed-air actuated pressure generator.Conventional air compressor has piston type air compressor, screw air compressor, centrifugal compressor, sliding-vane air compressor, scroll type air compressor, and screw air compressor is divided into again double-screw type air compressor and single screw air compressor.
Existing air compressor is the compressor of single working principle type, in an air compressor, namely only comprises piston type air compressor or only comprise screw-rod air compressor.The structure of piston type air compressor is simple, long service life, and easily realizes Large Copacity and High voltage output, but shortcoming is obvious, and vibration is large, and noise is large, and because exhaust is for intermittently to carry out, exports and have pulse, need gas tank.The screw-rod air compressor life-span is long, and noise is low, more energy-conservation, high efficiency, high-performance, maintenance cost are low, be easy to realize intelligent control, but exhaust pressure is high less than piston type air compressor.The noise of air compressor is the very large disadvantage existed in air compressor, and how to avoid strong noise to produce pressurized gas is a difficult problem simultaneously always.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of screw piston composite middle-high pressure air compressor is provided.
Screw piston composite middle-high pressure air compressor comprises screw air compressor motor, screw air compressor, oil gas filter, the first timing drainage valve, tube of pressure-stabilizing, the second timing drainage valve, the first pressure transducer, Piston Air Compressor, the second pressure transducer, safety valve, radiator be fixed on base, screw air compressor, oil gas filter, tube of pressure-stabilizing, second timing drainage valve, first pressure transducer, Piston Air Compressor motor, second pressure transducer, safety valve is connected in turn, screw air compressor motor is connected with screw air compressor by driving belt, oil gas filter is provided with the first timing drainage valve, tube of pressure-stabilizing is provided with the second timing drainage valve, Piston Air Compressor motor is connected with Piston Air Compressor by driving belt, Piston Air Compressor motor is connected with driving radiator, air compressor is controlled by control system, control system comprises master control system, first class control system and second control system, master control system joint control first class control system and second control system.
Described first class control system is VFC, controls screw air compressor and screw air compressor motor, oil gas filter, the first timing drainage valve, tube of pressure-stabilizing, the second timing drainage valve and the first pressure transducer.
Described second control system is VFC, control piston air compressor and Piston Air Compressor motor, the second sensor, safety valve and radiator.
Described master control system joint control first class control system and second control system.
Use the present invention, structure is simple, and hardware configuration is without particular/special requirement, and cost of production is low, easy and simple to handle.By appropriate design with mate front and back pressure and tolerance, played the advantage of two kinds of different operating principle compressors, mesohigh gas can have been produced when low noise, low vibration, low energy consumption, applied widely.Control system adopts VFC, and Stress control is accurately high, and Systematical control is reliable, safety, can reduce motor noise and extend electrical machinery life, reduces hardware cost.Entire system is divided into first class control system and second control system, carries out coordinated regulation by master control system, and modular Systematical control can improve the control accuracy of subtense angle, simultaneously the Security of elevator system.
