The centrifugal machine comprises a drive motor driven by a three-phase power supply, a control circuit of the drive motor is connected with a controller, and the controller comprises a phase dislocation protective relay, an open-phase protective relay and an excess voltage protective relay. The phase dislocation protective relay is provided with a phase dislocation indicating lamp, the open-phase protective relay is provided with an open-phase indicating lamp, and the excess voltage protective relay is provided with an excess voltage indicating lamp. The centrifugal oil purification system has the advantages of avoiding potential safety hazard and device damage caused by disordered phase sequence, default phase or overhigh voltage, effectively improving the safety and the reliability of the centrifugal machine in work, simultaneously achieving a function of automatically adding sealing water of the centrifugal machine, and improving the automation degree.
Description
?
Technical field
This invention relates to a kind of centrifugal oil purification system, particularly a kind of centrifugal oil purification system of charged protective device.
Background technology
Centrifugal oil purification system is the moisture that utilizes in the centrifuge oil and water separation, and the driving of centrifuge is to be driven by three phase electric machine.But the drive motors of centrifuge can the entanglement of three characteristics of the middle term power phase cause the loosening generation casualty accident that flies out of rotary drum inner member when initial start, operation brings potential safety hazard to equipment; Three phase mains can cause drive motors to burn because of phase shortage and voltage overrate in the running, brings economic loss to the user.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide a kind of centrifugal oil purification system that can avoid the charged protective device of potential safety hazard that centrifugal motor causes because of phase sequence entanglement or phase shortage and burn-down of electric motor.
Technical scheme: a kind of centrifugal oil purification system of charged protective device, comprise the inlet valve, inlet filter, heater, centrifuge and the delivery valve that are serially connected in successively in the working connection, described centrifuge comprises the drive motors that is driven by three phase mains, the control circuit of described drive motors is connected with controller, and described controller comprises fault-phase protection relay, phase failure relay and overvoltage protection relay; Described fault-phase protection relay is provided with the misphase indicator lamp, and phase failure relay is provided with disconnected phase indicator lamp, and described overvoltage protection relay is provided with the overvoltage indicator lamp.When if centrifuge starts generation three-phase power supply phase sequence entanglement phenomenon; the fault-phase protection actuating of relay is cut off centrifuge drive motors power supply while misphase indicator lamp and is lighted; phase sequence entanglement when reminding operating personnel to start; operating personnel restart after adjusting correctly, have effectively avoided the loosening accident generation that flies out and hurt sb.'s feelings of element in the rotary drum.When occuring power phase shortage or voltage above the safety value scope in the centrifuge running; phase failure relay or the overvoltage protection actuating of relay are cut off the electricity supply; disconnected phase indicator lamp or overvoltage indicator lamp light simultaneously; corresponding problem has occured in alert, can restart centrifuge after the problem for the treatment of solves.
In order to improve the automatic control degree of this cleaning system, described centrifuge sealing water oil-in is connected with water tank, and described tank top is provided with water pump, and the control circuit of described water pump is connected with controller.The delivery port of described water pump is connected with centrifuge sealing water filler, and the remote activation time-delay adds water, and water pump absorbs water from water tank and is filled into centrifuge sealing water filler, and water pump stops automatically behind the sealing water of filling certain hour.
Beneficial effect: the present invention has avoided centrifugal motor because the potential safety hazard that phase sequence entanglement, phase shortage or overtension cause and the generation of device damage problem, effectively improved the safety and reliability of centrifuge work, realize simultaneously the function of centrifuge automatic filling sealing water, improved automaticity of the present invention.
