[fan] refers to FRP FRP (FRP) fan material, its appearance, size and steel fan are exactly the same, just the shell and impeller for glass fiber materials, the characteristics of corrosion resistance, acid and alkali, belongs to a kind of anti-corrosion fan, widely used in glass fiber production process, refining of rare earth chemical, pharmaceutical, deodorization, papermaking, wastewater anaerobic acid recycling, electronic plating, plating, oxidation, power plant, laboratory, circuit board, environmental protection equipment containing corrosive gas. Then, FRP fan in the installation of how to debug it, for a long time, glass fiber reinforced steel for you briefly introduced:
1, glass steel fan allows full voltage starting or step-down start, it should be noted that the current rated current full voltage starting time is about 5-7 times, starting torque and voltage is proportional to the square, when the grid capacity is insufficient, should adopt the starting. When the power is greater than 11kW, the step-down start is adopted. )
2, glass steel fan in the test, should carefully read the instructions, check the wiring method is consistent with the wiring diagram; the working voltage should carefully check the fan power supply is not in accordance with the requirements, whether the power phase or the same phase, the electrical components of the capacity to meet the requirements.
3, the test of more than two people, a control power supply, a human observer fan operation, abnormal phenomena immediately stop check; check the rotation direction is correct; fan started running, should immediately check the operation current of the balance, if the current exceeds the rated current; if there is not a normal phenomenon that should be down to check. After five minutes running, stop to check whether the fan is abnormal, confirm no abnormal phenomenon, then turn on the machine.
4. When the fan reaches the normal speed, it should measure whether the fan input current is normal or not, and the running current of the fan can not exceed its rated current. If the operating current exceeds its rated current, check whether the supplied voltage is normal or not.
