Embodiment
The present invention is described in detail below in conjunction with embodiment.
Part description shown in Figure 1: 1. safety protective box 2. draught fan impellers 3. transmission groups 4. transmission shafts 5. coupling 6. frequency control motors 7. cabinets 8. vibration dampers.
The safe and reliable system safety testing device of plastic fan of the present invention is comprised of transmission group, transmission shaft, coupling, frequency control motor, cabinet, vibration damper, safety protective box and debugging unit.Testing apparatus is that 1 pair of draught fan impeller 2 of blower fan safety protective box runs up and shields, and transmission group 3 connection for transmission axles 4 connect frequency control motors 6 fixedly on the cabinet 7 by coupling 5, and the cabinet bottom is connected with vibration damper 8.
This device is connected to frequency control motor 6 and transmission group 3 on the cabinet 7, connect together by the output shaft of coupling 5 with the transmission shaft in the transmission group and frequency control motor again, there are two rolling bearings at transmission shaft two ends in the wheel hub of transmission group, driving transmission shaft 4 by frequency control motor rotates, transmission axle head connecting fan impeller 2, draught fan impeller is tested under high revolution, such as Fig. 2-voltmeter shown in Figure 5, ammeter, the tachometer circuit, the wattmeter circuit, the control loop circuit, converter circuit sets. given frequency, actual frequency, the motor actual current, motor is set rotating speed, the motor actual speed, accumulated running time, the controlling run time, the parameters such as output power of motor, the present invention is by the method for frequency control of motor speed, and draught fan impeller can obtain the test of different rotating speeds.On same test machine, can test the different draught fan impeller of size, can disposablely obtain needed correct numeral, reach good effect.For the vibrations that reduce cabinet are installed six vibration dampers 8 in the cabinet bottom.
For the safety that guarantees to test, impeller is installed in the safety protective box 1, inlays Mild Steel Expanded Sheets around the guard box, and Mild Steel Expanded Sheets namely plays protective action and do not block again sight line, and the impeller test process can observe directly running and test case.
During test, decide the highest test speed of test section strength coefficient and test usefulness according to payload when working, number of moving part and conveying Korrosionsmedium character etc.This maximum number of revolutions is input in the control panel, impeller is transitioned into the maximum number of revolutions of setting gradually when beginning to test by slow speed, and report lower operation 30 minutes at this, if impeller does not occur unusually, then impeller has safety and reliability, and voltmeter, ammeter, tachometer, wattmeter have recorded the data in the test simultaneously.If the impeller emerged in operation should in time shut down unusually, search reason according to unusual situation, targetedly impeller is improved.
