How much do you know the parameters of the radiator cooling fan test

The stand or fall of an automobile, to look at the host has the configuration of car, to determine the value of the car and good or bad. As part of the same to the quality of the radiator cooling fan is good or bad, it basically is to see the parameters of the thermal cooling fan, radiator cooling fan manufacturer of cooling fan test parameters, also determines the quality of their product, then the next by wen ling tong chi car air conditioning cooling cooling fan manufacturer of professional and technical personnel to introduce the parameter under our test standard: 1, rated voltage: refers to the cooling fan the best voltage {applicable to the normal working long hours Rated voltage error in 1. About 0 v} 2, rated current: refers to the cooling fan in the normal working current 3 under the rated voltage. Maximum current: refers to the cooling fan does not allow more than the TV university under rated voltage current { Less than or equal to 1. 15 * rated current} 4. The cooling fan pressure: refers to the division I test the cooling fan can withstand the highest voltage value { Less than or equal to 1. 15 * rated voltage} 5. Starting voltage refers to our test can start and to recognize the voltage value { Less than or equal to 1/2 or 1/3 * rated voltage} 6. Rated speed: refers to the cooling fan in the rated, room temperature conditions can withstand the heat dissipation fan speed { Rated speed error between 10% RPM} 7. Maximum air volume: refers to the cooling fan in zero static state test wind flow value of 8. Maximum voltage: refers to the cooling fan in the zero static state test of wind pressure value by 9. Noise: refers to the cooling fan in the absence of ring chamber { 18 dba} Environment, the cooling fan probe distance 1 m from the cooling fan noise test by size, 10. Different sound: refers to the cooling fan dry parts of 11 different sounds. Verticality and vibration: refers to the cooling fan rotor unbalance feel numbness caused by 12. Super box: refers to the cooling fan blades in no hyperplane plane countertops, wipe fan 13 of the bad situation. Dead center: dead and pseudo dead center points true: under the condition of rated voltage according to stop after the cooling fan to loosen, restart the power supply can't normal startup and operation. Pseudo dead point: under the condition of rated voltage according to the stop, the wind after loosening, restart the power supply cooling fan can normal startup and operation of 14. Current wave, the cooling fan according to { The cooling fan testing standard} Waveform standard test its size, symmetry, and other adverse conditions above is the knowledge of some standard radiator cooling fan parameters, wen ling chi car air conditioning cooling cooling fan manufacturers, professional provide radiator cooling fan, cooling fan, radiator dc cooling fan, blower and various specifications for industrial cooling dc cooling fan customization. 【 Ten years Taiwanese qualifications, two days out of the sample and price consultation: 13927478859] 13927478859
