Abstract
The utility model relates to a Roots blower controller. The Roots blower controller can be controlled to be started or shut down by pressing a starting button or a stopping button. The controller can be stopped emergently by pressing the stopping button when emergency circumstances occur. An intake pressure sensor and an exhaust pressure senor are used for measuring the air pressure values of the intake valve and the vent valve of the Roots blower and feed measured signals back to a singlechip, an outlet air temperature sensor and a bearing temperature sensor can measure the outlet air temperature of the vent valve of the Roots blower and the bearing temperature of a spindle, and feed measured signals back to the singlechip, and a pressure switch and a temperature switch both arranged on a fixed measuring point can measure the pressure value and the temperature value of the fixed measuring point and feed signals back to the singlechip. The singlechip feeds back all the measured values to a programmable logic controller (PLC) to calculate and process, and if deviation exists between the values and preset values, the singlechip controls an operation panel to sends sound-light alarm to remind a user that the Roots blower is abnormal.
Description
Technical field
The utility model relates to a kind of control system, is specifically related to a kind of roots blower controller.
Background technique
At present, roots blower has been widely used in the industries such as sewage treatment, it is the capital equipment of sewage treatment works, therefore its operation conditions is directly connected to the operation conditions of sewage treatment works, for it is monitored and generally takes a large amount of sensor installations, lays a large amount of signal cables to the method for robot control system(RCS) and realizes, not only cost is high, and reliability is also poor, therefore a large amount of roots blowers is not installed supervisory device, the equipment failure caused thus can be found everywhere.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides a kind of roots blower controller that can monitor in real time roots blower.
The utility model overcomes the technological scheme that its technical problem adopts:
This roots blower controller, comprise single-chip microcomputer, be connected in operation panel and the PLC of single-chip microcomputer, be installed on the air inlet pressure sensor of roots blower air inlet valve position, be installed on back pressure transducer and the leaving air temp sensor at roots blower gas outlet valve place, be installed on the bearing temperature sensor at roots blower main shaft bearing place, be arranged on pressure switch and thermal switch on fixed measuring point, start button, stop button, emergency stop button, described air inlet pressure sensor, back pressure transducer, bearing temperature sensor, the leaving air temp sensor, start button, stop button, emergency stop button all is connected in single-chip microcomputer.
In order to realize monitoring the current values of roots blower motor, also to comprise, be connected on the roots blower motor for the current transformer of induction machine electric current, described current transformer is connected in single-chip microcomputer.
For the cooling system of realizing roots blower can start automatically, also comprise water switch, the thermorelay A that is connected in the roots blower motor that controls the water cooling unit switch, the thermorelay B that is connected in cooling fan motor, described water switch, pressure switch, thermal switch, thermorelay A and thermorelay B all are connected in single-chip microcomputer.
The beneficial effects of the utility model are: can control and open or close this roots blower controller by pressing start button, stop button, can press emergency stop switch and make the controller emergent stopping when being in an emergency.The air pressure numerical value that air inlet pressure sensor and back pressure transducer go out for measuring roots blower suction valve and outlet valve, and by the signal feed back that records to single-chip microcomputer, leaving air temp sensor, bearing temperature sensor can be measured the air outlet temperature of roots blower outlet valve and the bearing temperature of main shaft, and by the signal feed back that records to single-chip microcomputer, the pressure switch and the thermal switch that are arranged on fixed measuring point can be measured pressure value and the Temperature numerical on fixed measuring point, and by signal feed back to single-chip microcomputer.Single-chip microcomputer feeds back to the PLC computing by all measurement numerical value, if numerical value and predefined value generation deviation, the Single-chip Controlling operation panel sends acoustooptic alarm, with reminding user roots blower abnormal now.
The accompanying drawing explanation
Fig. 1 is control system schematic diagram of the present utility model.
Embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be described further.
This roots blower controller, comprise single-chip microcomputer, be connected in operation panel and the PLC of single-chip microcomputer, the air inlet pressure sensor that is installed on the roots blower air inlet valve position, the back pressure transducer that is installed on roots blower gas outlet valve place and leaving air temp sensor, the bearing temperature sensor that is installed on roots blower main shaft bearing place, start button, stop button, emergency stop button, described air inlet pressure sensor, back pressure transducer, bearing temperature sensor, leaving air temp sensor, start button, stop button, emergency stop button all are connected in single-chip microcomputer.Can control and open or close this roots blower controller by pressing start button, stop button, can press emergency stop switch and make the controller emergent stopping when being in an emergency.The air pressure numerical value that air inlet pressure sensor and back pressure transducer go out for measuring roots blower suction valve and outlet valve, and by the signal feed back that records to single-chip microcomputer, leaving air temp sensor, bearing temperature sensor can be measured the air outlet temperature of roots blower outlet valve and the bearing temperature of main shaft, and by the signal feed back that records to single-chip microcomputer, the pressure switch and the thermal switch that are arranged on fixed measuring point can be measured pressure value and the Temperature numerical on fixed measuring point, and by signal feed back to single-chip microcomputer.Single-chip microcomputer feeds back to the PLC computing by all measurement numerical value, if numerical value and predefined value generation deviation, the Single-chip Controlling operation panel sends acoustooptic alarm, with reminding user roots blower abnormal now.
Also comprise and being connected on the roots blower motor for the current transformer of induction machine electric current, described current transformer is connected in single-chip microcomputer.Current transformer can be responded to the current values of roots blower motor when operation, and numerical value is fed back to single-chip microcomputer, single-chip microcomputer by the data feedback that gathers to the PLC computing, if the current values of induction surpasses the current value that circuit can carry, now the Single-chip Controlling operation panel sends acoustooptic alarm.
Also comprise water switch, the thermorelay A that is connected in the roots blower motor that controls the water cooling unit switch, the thermorelay B that is connected in cooling fan motor, described water switch, pressure switch, thermal switch, thermorelay A and thermorelay B all are connected in single-chip microcomputer.If collect the thermal switch that is arranged on fixed measuring point, be arranged on the leaving air temp sensor at roots blower gas outlet valve place and be arranged at Temperature numerical that the bearing temperature sensor at roots blower main shaft bearing place measures while surpassing Temperature numerical default in PLC through single-chip microcomputer, it is the roots blower cooling that thereby Single-chip Controlling water switch unlatching constituent is able to work, the cooling fan motor operation is controlled in thermorelay B adhesive, and then realizes air cooling effect.If the excess Temperature of measuring, thermorelay A can disconnect the electric current of roots blower motor, shuts down by force thereby control the roots blower motor, thereby further protects roots blower.
