Description
Technical field
The utility model relates to a kind of draught fan impeller testing apparatus, particularly relates to the overall plastic draught fan impeller fatigue resistance of a kind of high pressure testing apparatus.
Background technique
Overall plastic corrosion protection ventilator has application widely at chemical industry and metallurgy industry.Along with the development of modern industrial technology, more and more higher to flow and the pressure requirement of antiseptic ventilator.The critical component of antiseptic ventilator is exactly draught fan impeller, and the corrosive resistant fan impeller material has glass fibre reinforced plastics, steel lining glue, stainless steel, plastic plate welding at present.The above-mentioned impeller material of overall merit, the impeller Corrosion Protection optimum of plastic plate welding, but its fatigue resistance is poor than steel lining glue and stainless steel impeller.In order to ensure the fatigue resistance of plastic plate welding impeller in the production application process, can move safely and effectively, thereby the antisepsis when bringing into play it and carrying Korrosionsmedium is necessary to develop a kind of plastic impeller fatigue resistance testing apparatus.Because plastic materials and metallic material are incomparable, plastic materials is more much lower than Strength of Metallic Materials, so in the plastic fan impeller test process, should guarantee the accuracy of testing, Security and reliability in the time of also will guaranteeing impeller operation simultaneously.
Summary of the invention
The purpose of this utility model is to provide the overall plastic draught fan impeller fatigue resistance of a kind of high pressure testing apparatus.This device adopts automatic frequency-conversion, the variable-speed isolated plant, and the various draught fan impellers different to size carry out technology for detection at same test machine, disposablely obtain needed correct numeral, have guaranteed Security and the reliability of impeller.
The purpose of this utility model is achieved through the following technical solutions:
The overall plastic draught fan impeller fatigue resistance of a kind of high pressure testing apparatus, described device comprise transmission group, coupling, frequency control motor, cabinet, vibration damper, safety protection case and debugging unit; The transmission shaft of transmission group connects frequency control motor by coupling, and is fixed on the cabinet, and rolling bearing is equipped with at the two ends of transmission shaft in the wheel hub of transmission group, and the transmission axle head connects draught fan impeller, and the cabinet bottom is equipped with vibration damper.
The overall plastic draught fan impeller fatigue resistance of described a kind of high pressure testing apparatus, described impeller is installed in the safety protection case, inlays Mild Steel Expanded Sheets around the safety protection case.
Advantage of the present utility model and effect are:
The overall plastic draught fan impeller fatigue resistance of a kind of high pressure of the utility model testing apparatus adopts automatic frequency-conversion, the variable-speed isolated plant, the various draught fan impellers different to size carry out technology for detection at same test machine, disposablely obtain needed correct numeral, guaranteed Security and the reliability of impeller, made test reach good effect.

Embodiment
Below in conjunction with embodiment the utility model is elaborated.
Part description shown in Figure 1: 1. safety protection case 2. draught fan impellers 3. transmission groups 4. transmission shafts 5. coupling 6. frequency control motors 7. cabinets 8. vibration dampers.
The utility model plastic fan safety reliability testing apparatus is made up of transmission group, transmission shaft, coupling, frequency control motor, cabinet, vibration damper, safety protection case and debugging unit.Testing apparatus is that 1 pair of draught fan impeller 2 of blower fan safety protection case runs up and shields, and transmission group 3 connects transmission shafts 4 and connects 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, the transmission axle head connects draught fan impeller 2, draught fan impeller is tested under high revolution, 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, control working time, parameters such as motor output power, the utility model 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 protection case 1, inlays Mild Steel Expanded Sheets around the guard box, and Mild Steel Expanded Sheets namely plays protective action and do not block sight line again, and the impeller test process can observe directly running and test case.
During test, decide the highest test revolution 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 carried out the transition to the maximum number of revolutions of setting gradually when beginning to test by slow speed, and under reporting, this moves 30 minutes, if impeller does not occur unusually, then impeller has Security 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.
