Summary of the invention
The shortcomings that in order to overcome existing screw air compressor, the overlapping investment using unit to equipment is avoided, the present invention provides
A kind of screw pump, can for using unit simultaneously compressed air and vacuum requirement are provided, greatly reduce equipment investment and
Operating cost, while also achieving remotely monitoring and controlling by internet.
Technical solution provided by the invention: positive/negative-pressure one screw air compressor and intelligent controlling device, by negative-pressure cup, gas storage
Tank, screw pump and control device composition, wherein screw rod pump output terminal is connected to air accumulator by valve, and screw pump input terminal passes through
Valve is connected to vacuum tank.The valve that screw rod pump output terminal and air accumulator connect is triple valve, and import connects screw rod pump output terminal, one
Outlet connects air, and another outlet connects air accumulator.The valve that screw pump input terminal and vacuum tank connect is triple valve, and outlet connects spiral shell
Bar pumps input terminal, and an entrance connects air filter, and another entrance connects vacuum tank.Intelligent controlling device has main control unit by PLC micro-control list
Member and internet communication unit composition.Air accumulator has pressure sensor and main control unit electrical connection.Vacuum tank also has vacuum pressure
Sensor and main control unit electrical connection.Its control method is: when needing compressed air, main control unit is passed according to pressure at air accumulator
The work of signal the control screw pump and valve of sensor, when negative pressure has demand and positive pressure reaches peak, system passes through each biography
The data that sensor provides adjust the trend of gas, and equipment is allowed to work normally.
The beneficial effects of the present invention are: can greatly be dropped to provide compressed air and vacuum requirement simultaneously using unit
Low equipment investment and operating cost, while also achieving and remotely being monitored and controlled by internet.

Specific embodiment
In Fig. 1, positive/negative-pressure one screw air compressor and intelligent controlling device, by air accumulator (2), negative-pressure cup (3), screw pump
(15) it is formed with control device (18), wherein screw rod pump output terminal is connected to storage by valve, that is, screw rod pump output terminal triple valve (7)
Gas tank (2), screw pump input terminal are connected to vacuum tank (3) by valve, that is, screw pump input terminal triple valve (12).Screw pump output
The valve that end and air accumulator (2) connect is that triple valve i.e. screw rod pump output terminal triple valve (7), import connects screw rod pump output terminal,
One outlet connects air scoop (6), and another outlet connects air accumulator (2).The valve that screw pump input terminal and vacuum tank (3) connect is threeway
Valve, that is, screw pump input terminal triple valve (12), outlet connect screw pump input terminal, and an entrance connects air filter (13), and another entrance connects
Vacuum tank (3).Intelligent controlling device has main control unit by PLC micro control unit (18) and internet communication unit i.e. communication module
(17) it forms.Air accumulator has pressure sensor (5), main control unit (18) electrical connection.Vacuum tank (3) also has vacuum sensor
(11) it is electrically connected with main control unit (18).Its control method is: when needing compressed air, main control unit (18) is according to air accumulator
(2) work of signal control screw pump (15) and each valve of pressure sensor (5) at, when negative pressure has demand and positive pressure reaches most
When high level, system controls the work of each valve by data that each sensor provides, so as to adjust the trend of gas, allows equipment
It works normally.Wherein compressed air delivery outlet (1) provides compressed air, and negative pressure delivery outlet (4) provides negative pressure.Pass through communication module
(17) access area net or internet can also be realized with entire production control system interacts, and accomplishes intelligent control and feedback.It is real
Effective allotment of existing people, machine, material.
In this way, realizing on the same device is both vacuum equipment and air compressor, reduce than traditional equipment
The waste of resource, while the waste of the energy can also be reduced.Positive/negative-pressure Intelligent screw pump has outstanding in terms of energy conservation and environmental protection
Performance.
In practical applications, check valve can also be increased before air accumulator, vacuum tank, air filter etc., before oil strainer
Increase temperature-sensing element after or.Positive/negative-pressure Intelligent screw air compressor machine gives host supplying power first, and (plc control is single for starting control system
Member), parameters are set, system carries out equipment self-inspection program, and self-test is powered by starting later to drive motor, air compressor machine
It starts to work when air pressure reaches preset value, high pressure sensor, which signals to centralized control system, allows drive motor to stop working,
Equipment enters standby mode, when negative pressure has demand and positive pressure reaches peak, system by data that each sensor provides come
The trend for adjusting gas, allows equipment to continue to work normally, positive pressure is also such.In the equipment course of work if air themperature,
The excessively high control system of oil temperature can open radiator fan to cool down.The operating condition of system meeting real-time monitoring equipment, has any
System will emergency shutdown when sensor reaches alarming value.
