Note the fan housing or motor housing ground must be reliable; prohibited in the opposite direction of rotation, constant current over-running ban prohibiting missing running; no maintenance fan in operation. Debugging fan allows full pressure start or step-down start, it should be noted, Foshan soil Wo Equipment fans, current at full voltage starting time of about 5 to 7 times the rated current, voltage starting torque with a current proportional to the square, when the grid insufficient capacity, should be used to step-down start. (When the power is greater than 11KW, should adopt the step-down start.) The fans at the test, you should carefully read the product manual, check the wiring method is consistent with the wiring diagram; should carefully check the operating voltage of the power supply fan meets the requirements, the power supply is missing phase or same phase, the electrical components with a capacity to meet the requirements. When the test at least two persons, one person control power, one observes fan operation, abnormal phenomenon immediately stop inspection; First check the direction of rotation is correct; after the fan begins to run should immediately check whether an operating current balance, current exceeds rated current; if there is a normal phenomenon, should stop to check. After running for five minutes, Soil Wo equipment, down to check whether the fan abnormal phenomenon, confirmed that no anomalies start running again. When the two-speed fan test, you should start low, and check the direction of rotation is correct; it must be stationary before starting the fan speed to the start time, to prevent the high-speed reverse rotation, causing the switch to trip and motor damage. The fan up to speed, the fan should be detected input current is normal, the fan operating current not exceed the rated current. If the operating current exceeds the rated current, the fan should check the supply voltage is normal. Fan motor power is required to refer certain conditions, for centrifugal fan and wind chassis, the required high power inlet fully open. If the inlet operated fully open, the motor may be damaged. When the test is best to fan the fan inlet or outlet piping of the valve is closed, the operation will gradually open the valve, until the desired working conditions, and pay attention to the fan operating current exceeds the rated current. Preparation before the fan out of the box should check the packaging is intact, the fan nameplate parameters to meet the requirements, each comes with complete accessories are complete. Carefully inspect the fan during transport without deformation or damage, fasteners are loose or fall off, whether there are collision phenomenon impeller, and inspect the various parts of the fan. If found abnormal, should be repaired before use. Insulation resistance 500V megger fan housing and motor windings, three water and soil Wo Equipment fan, its value should be greater than 0.5 megohms, or deal with the motor windings powerful horse for drying, when drying temperature must not exceed 120 ℃. Ready for all kinds of materials, tools and space fan installation. Soil Wo Equipment (FIG), Shunde soil Wo Equipment fan soil Wo Equipment provided by Goldman Equipment Co., Ltd. Foshan City.
