Description of drawings
Fig. 1 is the schematic representation of the utility model to the control of blower fan, coupler rotating speed;
Fig. 2 is the schematic representation of the utility model to lubricating oil system control.
Embodiment
Control to the hydraulic speed-regulating coupler that is fit to 65 tons of steel-making dusting apparatus blower fans configurations is by the motor final controlling element, three part compositions of control of working oil system and lubricating oil system control.
As shown in Figure 1, to the control of blower fan, coupler rotating speed
Control gear comprises that control box 13, motor final controlling element 14, operator 12, INTELLIGENT TACHOMETER (not shown) and are connected computer 15 between control box and the operator, wherein: computer 15 carries out rotating speed control by 12 pairs of motor final controlling element of operator 14, and measures the output shaft rotating speed and be input to computer 15 and carry out feedback control by being installed in output axle head INTELLIGENT TACHOMETER.
The rotating speed of blower fan must carry out speed governing, the output shaft gang of blower fan and coupler with the process of steel-making.Therefore as long as the coupler output shaft is carried out speed governing, just can satisfy in the steelmaking process needs to load.A given rotating speed, computer 15 is controlled by 12 pairs of motor final controlling element 14 of operator, wait by the cam link mechanism on the machine, tooth sector and to control scoop tube radial position in rotation case, promptly controlled the level height of working oil in pump, the turbine shape chamber, also controlled the open degree of working oil control valve, thereby finished the function that turbine (output shaft) has been carried out speed governing, and measure the output shaft rotating speed by being installed in output axle head INTELLIGENT TACHOMETER, be input to and just formed a control procedure in the computer.Realized the automation of speed regulation process.
Test the speed operator and computer of the pressure and temperature of the currrent feedback of motor final controlling element, the pressure and temperature of working oil, lubricant oil, output shaft rotating speed joined together to form the ring of a sealing.Available manually and the CRT screen operation of computer, reach the control automation with the CRT screen operation of computer.
As shown in Figure 2, lubricating oil system control
To lubricating oil system control is that normal utilization to fluid coupling has played guaranteeing role.The gear pump 1 that lubricating oil system is driven by main motor, the pre-oil feed pump 2 that is driven by motor 3, one-way valve 4, lubricating oil pressure pressure regulator valve 5, oil cooler 6, two-way filter 7, thermocouple 8, pressure gauge 9, pressure transmitter 10 and fuel tank 11 are formed by connecting by pipeline.Monitoring elements such as oil temperature, oil pressure all are connected with control system.
At first start pre-oil feed pump, pre-oil feed pump pumps lubricant oil from fuel tank, flow to each lubricating point of system, (comprising motor and blower fan).When lubricant oil reaches 0.1Mpa, start main motor automatically, drive coupler, start the oil filling pump of coupler.Gear pump (1) pump oil when lubricating oil pressure reaches 0.2Mpa, cuts off pre-electric current for pump motor automatically.Pre-oil feed pump fuel cut-off.Coupler enters the normal operation stage, and the coupler output terminal is passed to blower fan by the gear shaft coupling with moment of torsion.When the temperature and pressure of lubricant oil surpasses a certain setting value, give the alarm, cut off the electric current of main motor simultaneously automatically, start pre-oil feed pump, continue to give each lubricating point that lubricant oil is provided, stop operating until main motor.Avoid special circumstances to take place and caused the interruption of lubricant oil, the damage of bearings of coupler, blower fan and motor has taken place, ensured the normal operation of whole each equipment of blower fan system.
